  • Record of occurrence of Nasua nasua (Linnaeus, 1766) (Carnivora,
           Procyonidae) in a densely urbanized area of the city of Canoas, southern
           Brazil

    • Abstract: Neotropical Biology and Conservation 17(2): 111-116
      DOI : 10.3897/neotropical.17.e81824
      Authors : Diego Floriano da Rocha, Thaís Brauner do Rosario, Ana Carolina Pontes Maciel, Duana Suelem Alves, Cristina Vargas Cademartori : The South American coati is a carnivore with a wide distribution in South America. Despite this, it is considered a threatened species in Rio Grande do Sul, as Vulnerable, primarily because of the loss of forest habitats. We recorded a Nasua nasua individual at the Canoas airbase, one of the last remaining green spaces in a densely urbanized area in southern Brazil. This confirms the capability of this species to use environments that have been changed by anthropic activity. It also highlights the relevance of green spaces in urban areas for wildlife conservation. HTML XML PDF

  • Recent observations of Dermochelys coriacea (Vandelli, 1761), in the
           waters of Pacific Panama

    • Abstract: Neotropical Biology and Conservation 17(1): 103-110
      DOI : 10.3897/neotropical.17.e81465
      Authors : Eric E. Flores : The situation of the Eastern Tropical Pacific subpopulation of the leatherback sea turtle (Dermochelys coriacea) is critical due to the drastic declines of nesting females. Evidence of the presence of leatherback sea turtles along the Pacific coast of Panama is anecdotal and is based on the local knowledge of local residents. I present here an uncommon observation of a subadult and an adult D. coriacea in the waters off the coast of Azuero Peninsula in central Panama. These observations indicate the need for intensive surveys along this coast that in part may rely on key local informants to urgently implement conservation efforts for this species. HTML XML PDF

  • The importance of pollination and dispersal syndromes for the
           conservation of Cerrado Rupestre fragments on ironstone outcrops immersed
           in an agricultural landscape

    • Abstract: Neotropical Biology and Conservation 17(1): 87-102
      DOI : 10.3897/neotropical.17.e79247
      Authors : Cássio Cardoso Pereira, Daniel Meira Arruda, Fernanda de Fátima Santos Soares, Rúbia Santos Fonseca : Studies on pollination and seed dispersal are essential for the conservation of plant diversity. In this study, we aimed to evaluate the pollination and dispersal syndromes of five fragments of the Cerrado Rupestre immersed in an agricultural landscape to answer the following questions: (i) What is the frequency of pollination and dispersal syndromes among species and individuals'; (ii) Which are the predominant pollination and seed dispersal syndromes in this environment'. A total of 66 species, belonging to 44 genera and 29 botanical families, were evaluated. Melittophily was the most common type of pollination syndrome, observed in 54.55% of the species, followed by phalenophily (9.09%), cantharophily, ornithophily, quiropterophilly and sphingophily (all 3.03%), and psychophilly (1.51%). Generalist pollination represented 22.73% of the records. Of the 1246 individuals identified, 59.23% were melitophilous, 25.20% generalists, 5.86% phalenophilous, 3.37% quiropterophilous, 2.49% cantharophilous, 2.25% ornithophilous, 1.44% sphingophilous and 0.16% psychophilous. Regarding dispersion syndromes, zoochory was the most common type of dispersion, observed in 68.18% of the species, followed by anemochory (28.79%) and autochory (3.03%). On the other hand, the frequency among individuals differed from the values found for frequency among species. Of the 1246 individuals identified, 55.38% were anemochoric, 43.10% zoochoric, and 1.52% autochoric. Our results demonstrate the predominance of biotic syndromes in the community, especially melittophily and zoochory, contributing to a better understanding of the functionality and availability of resources in the community, as well as indispensable information for the conservation, management, and restoration of natural environments.

  • Non-native freshwater fishes in Guatemala, northern Central America:
           introduction sources, distribution, history, and conservation consequences
           

    • Abstract: Neotropical Biology and Conservation 17(1): 59-85
      DOI : 10.3897/neotropical.17.e80062
      Authors : Diego J. Elías, César E. Fuentes-Montejo, Yasmín Quintana, Christian A. Barrientos : Non-native freshwater fishes have been introduced to Guatemalan freshwater ecosystems since the beginning of the last century without prior risk assessment or subsequent evaluation of their impacts. We synthesized historical records, and distributional data from a literature review, online databases and museum records of non-native freshwater fishes in Guatemala. We found records for 22 non-native freshwater fishes with the oldest records dating back to 1926. Non-native freshwater fishes were recorded in 64% of the river sub-basins in Guatemala and we identified that at least 12 species have established populations. The Jaguar guapote (Parachromis managuensis) and Tilapias (Oreochromis spp.) are the most widespread non-native fishes. The species of non-native freshwater fishes introduced indicates that they are human selected (e.g., for farming purposes). Our work shows that aquaculture has been the major driver of introductions in the country, but aquarium release has become an important source in the last 20 years. Given the potential impact of non-native freshwater fishes on native fauna and ecosystems, we highlight an urgent need to assess their ecological effects, as well as to establish a fish fauna monitoring program in Guatemala to detect new introductions. Government and non-governmental agencies should promote the use of native species to supply fish demands in alignment with environmental policies and the objectives of the fishing agency in Guatemala.

  • Taxonomic and functional diversity of birds in a rural landscape of
           high Andean forest, Colombia

    • Abstract: Neotropical Biology and Conservation 17(1): 39-57
      DOI : 10.3897/neotropical.17.e66096
      Authors : Lina P. Sarmiento-Garavito, Juan S. García-Monroy, Juan E. Carvajal-Cogollo : We evaluated the taxonomic and functional diversity of birds in a rural landscape in the north-eastern Andes of Colombia. We carried out seven field trips and used transects of 300 m, separated from each other by 500 m in the dominant plant cover of the rural landscape. We measured alpha (α) and beta (β) diversity at both the taxonomic and functional levels. We registered 10 orders, 21 families, 56 genera and 63 species of birds. In wooded pasture, we recorded 55 species and a relative abundance of 66% and 44 and 34% for an Andean forest fragment. The species that contributed the most to the dissimilarity between the covers were Zonotrichia capensis, Turdus fuscater, Mecocerculus leucophrys, Atlapetes latinuchus and Crotophaga ani. We identified nine functional types, where G1 was made up of small species with anissodactyl and pamprodactyl legs that were insectivorous, frugivorous and nectarivorous as the best represented. The FEve and FDiv were 0.51 and 0.74, respectively in the Andean forest fragment plant cover and, for the wooded pasture, the FEve was 0.45 and the FDiv was 0.81. Both cover types contributed to the diversity of the rural landscape and the dynamics that existed between them formed a complementary factor that favoured the taxonomic and functional richness of the characterised rural landscape.

  • Abundance of the Resplendent Quetzal Pharomachrus mocinno
           (Trogoniformes, Trogonidae) in the tourist sector of a cloud forest
           reserve

    • Abstract: Neotropical Biology and Conservation 17(1): 29-38
      DOI : 10.3897/neotropical.17.e72273
      Authors : Javier Adolfo García Reynaud, Miriam Elizabeth Sorto Sabillón, Allan Francisco Padilla Barahona : The Resplendent Quetzal (Pharomachrus mocinno) exhibits characteristics that are common to species prone to extinction, such as occurring at low densities, presenting strict ecological requirements, and inhabiting locations with high rates of degradation. The lack of data on the abundance of threatened species makes it difficult to make management decisions and does not allow to know trends over time, which is essential for conservation in their distribution areas. The abundance and density of the Resplendent Quetzal was estimated from audio/visual detections analyzed with distance sampling techniques. Data was collected in the public use sector of La Tigra National Park, a reserve of virgin and secondary growth cloud forest in Honduras, Central America. A population N = 136 was found with a density of 40 quetzals per km2. There are no systematic studies on the population size and density of the species for this site since 1979, in which a population of 145 quetzals was reported. The estimation of the Resplendent Quetzal population for the total area of the park is a main research priority, which will make it possible to evaluate the viability of the species and the establishment of a new baseline for conservation policies and environmental education efforts in the area of influence.

  • Confirmation of the current occurrence of Nasua narica (Procyonidae) in
           the Caribbean region of Colombia

    • Abstract: Neotropical Biology and Conservation 17(1): 21-28
      DOI : 10.3897/neotropical.17.e70352
      Authors : Gerson A. Salcedo-Rivera, Alberto Mario Rodríguez, Dairo Carrascal-Prasca, Ramón Granados-Peña, José F. González-Maya : The White-nosed Coati, Nasua narica is a small carnivore distributed from the United States to Ecuador, and whose occurrence in Colombia had only been confirmed from the biogeographic Chocó. Although it was previously erroneously considered widespread in the country, a recent revision identified inconsistencies with some supporting records there. Here we present a new distribution record for the species, which confirms previously alleged information about the presence of this procyonid in the Department of Magdalena, also confirming its current occurrence for the Caribbean region, and solving a long-due geographical distribution uncertainty in the country.

  • The distribution and conservation status of Tapirus terrestris in the
           South American Atlantic Forest

    • Abstract: Neotropical Biology and Conservation 17(1): 1-19
      DOI : 10.3897/neotropical.17.e71867
      Authors : Kevin M. Flesher, Emília Patrícia Medici : Tapirus terrestris is the largest South American land mammal, with an extensive historical distribution and capable of occupying diverse habitats, and yet its populations have declined across its range. In order to provide baseline data on the conservation status of tapirs in the Atlantic Forest, we conducted a long-term study in one landscape, visited 93 forests, and received 217 expert reports over the 15-year study. We estimate that 2,665–15,992 tapirs remain in 48 confirmed populations, occupying 26,654 km2 of forest or 1.78% of its original range in the biome. Historically, hunting and deforestation were the main causes of decline, but today population isolation is the principal long-term threat. Vortex models indicate that 31.3–68.8% and 70.8–93.8% of the populations are demographically and genetically non-viable over the next 100 years, respectively, and that only 3–14 populations are viable when considering both variables. Habitat use data indicate that tapirs are adaptable to disturbed and secondary forests and will use diverse tree plantations and agricultural lands but hunting and highways keep populations isolated. Reserve staff report tapirs as common/abundant at 62.2% of the sites, and populations as stable and growing in 60% and 36% of the sites, respectively, and there is ample habitat in the biome for a population expansion, but overcoming the causes of isolation will be necessary for this to occur. Lack of adequate funding for protecting reserves is a chronic threat throughout the biome, especially in federal and state/provincial reserves, and increased funding will be necessary to implement effective conservation plans.

  • Human-wildlife conflicts and drought in the greater Calakmul Region,
           Mexico: implications for tapir conservation

    • Abstract: Neotropical Biology and Conservation 16(4): 539-563
      DOI : 10.3897/neotropical.16.e71032
      Authors : Jonathan Pérez-Flores, Sofía Mardero, Antonio López-Cen, Fernando M. Contreras-Moreno : Wildlife conservation efforts in the Mesoamerican Biological Corridor have focused on reducing negative interactions between humans and charismatic species. In recent years, droughts have increased in frequency and intensity in southeastern Mexico exacerbating conflicts with wildlife as they compete with humans for limited water. In the Yucatan Peninsula, Greater Calakmul Region of southeastern Mexico, Baird’s tapirs (Tapirus bairdii) are increasingly encroaching into local villages (ejidos) in search of water. This behavior could increase tapir mortality from hunting by Calakmul ejidos residents. We evaluated the trends between annual precipitation and tapir sightings near or within Calakmul ejidos from 2008 to 2019 to determine if the frequency of reported conflicts increased relative to decreased precipitation. In addition, with community participation, from 2016 to 2018 we monitored one of the ejidos where human-tapir conflicts were reported to be increasing to better describe the nature of conflicts. We did not find any relationship between the number of tapir sightings reported and annual precipitation. However, more tapirs were documented near ejidos in 2019, which is one of the years with the lowest rainfall (626.6 mm) in the last decade. Tapirs were reported as the most common wildlife species observed at waterholes (35.4%) and apiaries (32.1%). Our findings suggested that water scarcity has increased tapirs’ incursions into human-populated areas and subsequently the potential for human-tapir conflicts. We recommend that managers consider developing alternative water sources that could mitigate human-tapir conflicts and contribute to the long-term viability of other wildlife species that inhabit the Greater Calakmul Region of southeastern Mexico.

  • Strandings of sea turtles on beaches around the oil capital in
           Brazil

    • Abstract: Neotropical Biology and Conservation 16(4): 521-538
      DOI : 10.3897/neotropical.16.e68662
      Authors : Raísa da Silva Costa Rêgo, Eric Azevedo Cazetta, Caio Henrique Gonçalves Cutrim, Amanda Soares Miranda, Ana Paula Albano Araújo, Vinícius Albano Araújo : The south-western region of the Atlantic Ocean has feeding and nesting areas for the five species of sea turtles registered in Brazil, which are in different degrees of extinction threat, mainly due to anthropogenic factors. Fishing and the ingestion of solid waste, were identified as causing stranding and the mortality of sea turtles. In this work, data from the monitoring of beaches in the Municipalities of Macaé and Rio das Ostras, important oil zone in Brazil, in the north-central region of the State of Rio de Janeiro, were used in order to analyse the effects of seasonality on the sea turtle stranding. The monitoring was carried out daily from September 2017 to June 2019, in a study area covering 23.8 km long beach. Stranding data were obtained from active (n = 126) and passive (n = 66) monitoring of beaches and included the records of Chelonia mydas (n = 151), Caretta caretta (n = 23), Lepidochelys olivacea (n = 14), Dermochelys coriacea (n = 2) and Eretmochelys imbricata (n = 1). The largest stranding record occurred in the summer (n = 61) and spring (n = 60), a period compatible with the reproductive season of the species. The results obtained in this study emphasise the importance of the analysis of strandings of sea turtles, which provide relevant data on the biology of the group, the intra and interspecific dynamics and the state of conservation of these animals.

  • Behavior, ecology and territory of the chestnut-bellied hummingbird,
           Saucerottia castaneiventris, in the xerophytic vegetation of the
           Chicamocha canyon of Colombia

    • Abstract: Neotropical Biology and Conservation 16(4): 501-520
      DOI : 10.3897/neotropical.16.e66094
      Authors : Gerson Marcel Peñuela Díaz, Ludy Archila-Durán, Jorge Parra, Juan E. Carvajal‑Cogollo : The Chestnut-bellied Hummingbird Saucerottia castaneiventris is an endemic hummingbird of Colombia, currently categorized as Near Threatened (NT) globally and as Vulnerable (VU) in Colombia. We characterize the territorial defense and foraging behaviors of S. castaneiventris hummingbird during different seasons of the year, and we determined the size of the S. castaneiventris territory and its relationship with floral abundance at different times of the year. We made four field trips between 2008 and 2009 and registered 19 individuals from S. castaneiventris. Of these, 10 were in the rainy periods, distributed in five territories (one male and one female for each). Eight were in the dry period (July), distributed in four territories. And one individual was in the dry period of February, which did not settle in any of the identified territories. Territorial defense occupied a large part of species’ time. The nectar drinking, and insect hunting were the most frequent activities. The most common floral resources were Opuntia dillenii, Tillandsia sp. and Aloe vera. The hummingbirds Chlorostilbon gibsoni and Doryfera ludoviciae shared habitats with S. castaneiventris and there were fluctuations in encounter rates between the seasons (C. gibsoni ER: 20–7.5 and D. ludoviciae and ER: 0.0–2.5). Territories ranged between 1800 and 3800 m2 for the dry season and between 1500 and 6500 m2 for the rainy season. Our results provided primary information on the ecology of S. castaneiventris and form the basis for the formulation of conservation strategies for the species and for its habitats.. HTML XML PDF

      Authors : Teresa López-Romero, O. Eric Ramírez-Bravo, E. Evangelina Camargo-Rivera, Daniel Jiménez-García, Héctor Bernal-Mendoza, Roberta Marques : We describe a case of mucormycosis in a Lesser Long-nosed Bat (Leptonycteris yerbabuenae) caused by Apophysomyces elegans in Puebla, Central Mexico. The diagnosis was supported by laboratory analysis and necropsy. We present the first report of the fungus in a wild host; therefore, we indicate that further studies are necessary to understand its infection cycle since this pathogen may indicate a risk of zoonotic, and anthropozoonotic diseases.

  • Can guava monocultures (Psidium guajava L.) function as refuge for bird
           conservation'

    • Abstract: Neotropical Biology and Conservation 16(4): 475-491
      DOI : 10.3897/neotropical.16.e70296
      Authors : Cleverton da Silva, Juan Ruiz-Esparza, Fabiana Oliveira da Silva, Cristiano Schetini de Azevedo, Adauto de Souza Ribeiro : Agricultural intensification negatively affects bird communities, and the response of birds to these changes varies from those that survive and increase their populations (disturb-tolerant species) to those that cannot adapt to new conditions and are regionally extinct (disturb-sensitive species). Thus, the present study sought to investigate the bird community in 39 guava orchards in the semiarid region of the state of Sergipe, northeast Brazil. Field observations were made between July and October 2017, through a one-hour visit to each orchard. Samplings were conducted using the MacKinnon’s List method. In addition to bird sampling, walks were carried out in the orchards to observe nesting. Seventy-six species of birds belonging to 30 families were recorded using the guava orchards. The most frequent species were Vanellus chilensis, Columbina talpacoti, Columbina picui, Crotophaga ani, Pitangus sulphuratus and Sporophila albogularis. Of the 186 nests recorded in the orchards, the majority (n = 144 nests; 77.4%) belonged to Columbina picui, Columbina talpacoti and Columbina minuta. The results demonstrate that the bird community in the guava orchards is formed only by disturb-tolerant species, showing that the studied guava orchards are not favorable to the conservation of disturb-sensitive birds of the Caatinga domain.

  • Dog predation by jaguars in a tourist town on the Mexican Caribbean

    • Abstract: Neotropical Biology and Conservation 16(4): 461-474
      DOI : 10.3897/neotropical.16.e68973
      Authors : Mónica Carral-García, Irene Buenrostro, Holger Weissenberger, Víctor Rosales, Jonathan Pérez-Flores : Invasion of humans and dogs into the jaguars’ habitat opens the way for future negative events. Dog predation by jaguars has only been recorded anecdotally, despite the high risk of pathogen transmission and the potential conflict due to pet predation. In this study, we document jaguar attacks on dogs in Mahahual, Quintana Roo, Mexico, a tourist town in the Mexican Caribbean. In addition, we describe an initiative designed to prevent jaguar persecution by constructing night houses for dogs at the most recent attack sites. A total of 20 attacks were recorded in the last nine years, most of them fatal (60%) on medium-sized dogs (70%), at night (95%) and during the dry season (65%). Half of the attacks occurred in the north of Mahahual´s coastline and the other half in the south. Attacks in the south were concentrated between 0 to 10 km away from the village, while in the north they were dispersed over distances between 0 and > 30 km. Thirty-eight night houses were constructed covering almost 45 km of the 135 km of Mahahual’s coastline. Further research is required to understand the importance of dogs in the jaguar diet and the impact of dog predation on the health and disease ecology of jaguar populations. HTML XML PDF

  • New records on the distribution and habitat of the northern naked-tailed
           armadillo, Cabassous centralis (Mammalia, Cingulata, Chlamyphoridae) in
           Costa Rica

    • Abstract: Neotropical Biology and Conservation 16(3): 451-460
      DOI : 10.3897/neotropical.16.e67969
      Authors : Pablo Marín, José Manuel Mora, Lucia I. López, José Alberto Pérez Arrieta, Miguel A. Rodríguez, Alison Vega Cambronero, Ignacio Arias : The northern naked-tailed armadillo, Cabassous centralis, is a rare and elusive species. It ranges from southern Mexico to northern South America. It has been detected in several types of habitats, but appears to prefer Tropical and Subtropical broadleaf forests. In Costa Rica, this species is difficult to observe and there are only eight records reported in the scientific literature. To search records of this armadillo, we used camera traps in north-western Costa Rica and visited several additional localities in the centre and the Caribbean lowlands of the country. We also examined and assessed records of this species from the Global Biodiversity Information Facility (GBIF) database. We added four new locality records for C. centralis in Costa Rica, based on photos from camera traps and field observations. We found only three localities (five records) in GBIF additional to the eight reported in literature. Habitat in these new Costa Rican localities reported here varied from mature dense forest (one site) to semi-urban areas (two sites). Additionally, two individuals were detected in secondary forest patches, one of them adjacent to mature riparian forest. Given the species’ scarcity, much additional information still is required to ground protection actions in a scientific framework. HTML XML PDF

  • Amphibians of the Sinos River Basin, southern Brazil

    • Abstract: Neotropical Biology and Conservation 16(3): 435-449
      DOI : 10.3897/neotropical.16.e65843
      Authors : Camila F. Moser, Renata K. Farina, Márcio Borges-Martins, Iberê F. Machado, Patrick Colombo, Alexandro M. Tozetti : The Sinos River encompasses a wide area of natural habitats and, at the same time, supports one of the highest population densities of southern Brazil. Consequently, natural habitats along the Basin present a high degree of habitat disturbance. Despite of the existence of threatened species, information about diversity of amphibians in that area is scarce. Thus, we aimed to catalogue the amphibian species of the Sinos River Basin from records in scientific collections and compilation of published articles. We recorded 52 species, all with geographic coordinates validated at the collection point, indicating that the Sinos River Basin harbours about 50% of the amphibian species of the State of Rio Grande do Sul. Three anuran species were classified as having some degree of threat: Melanophryniscus cambaraensis, Melanophryniscus dorsalis and Thoropa saxatilis. We also expected other 18 species with a high probability of occurrence in the Basin. This work shows that, despite the intense human impact, the Sinos River Basin has a relevant role for the maintenance of a considerable fraction of the amphibian biodiversity in southern Brazil.

  • First Locality Record of Melanistic Oncilla (Leopardus tigrinus) in
           Monteverde, Costa Rica

    • Abstract: Neotropical Biology and Conservation 16(3): 427-434
      DOI : 10.3897/neotropical.16.e65464
      Authors : Jordan E. Rogan : The persistence of the coat color polymorphism melanism has been reported for several tropical felids, but its evolutionary advantages remain an active area of research. Few publications have explored melanism in the elusive species, oncilla (Leopardus tigrinus) within the Neotropical part of their range in Costa Rica. Herein, I present the first record of a melanistic oncilla within the montane cloud forest of Monteverde, Costa Rica. Recent studies have found support for theories (e.g. Temporal Segregation Hypothesis and Gloger’s Rule) explaining the ecological advantages driving melanism in oncilla and tropical felid populations. However, it is unclear what is driving melanism in this Monteverde oncilla population due to the singular observation. Further research investigating whether melanism is occurring at a higher frequency in other individuals in the region is critical to better understanding the occurrence of melanism in local populations of this cryptic species. The montane cloud forest in Monteverde provides critical habitat to this vulnerable species within the small Neotropical part of their range. Melanistic individuals may be particularly threatened by land-use change and increasing human pressure if theories for the evolutionary advantages and ecological conditions motivating melanism are supported.

  • Increasing reality of species distribution models of consumers by
           including its food resources

    • Abstract: Neotropical Biology and Conservation 16(3): 411-425
      DOI : 10.3897/neotropical.16.e64892
      Authors : Gabriel Preuss, André Andrian Padial : Species distribution models are not usually calibrated with biotic predictors. Our study question is: does the use of biotic predictors matter in predicting species distribution' We aim to assess the importance of biotic predictors in the output of distribution models of the Brazilian squirrel (Sciurus aestuans) throughout South America based on fruits of Syagrus romanzoffiana – the most consumed food resource. We hypothesized that the distribution model of S. aestuans using its main food resource as a biotic predictor will be more accurate in comparison with the output of the model without the biotic predictor. We built three different distribution models: (i) distribution of S. romanzoffiana; (ii) distribution of S. aestuans without biotic predictor; and (iii) distribution of S. aestuans with biotic predictor. We evaluated performance scores, number of presence pixels and concordance between suitability maps. We found that performance scores may not vary between models with different predictors, but the output map changed significantly. We also found that models with biotic predictors seem to vary less in presence pixels. Furthermore, the main variable in the distribution model was the biotic variable. We conclude that the knowledge of a species’ biology and ecology can make better predictions of species distribution models mainly by avoiding commission errors. HTML XML PDF

  • New morphological data on the rare sigmodontine Mindomys hammondi
           (Rodentia, Cricetidae), an arboreal oryzomyine from north-western Andean
           montane forests

    • Abstract: Neotropical Biology and Conservation 16(3): 397-410
      DOI : 10.3897/neotropical.16.e65875
      Authors : Jorge Brito, Nicolás Tinoco, Jenny Curay, Ulyses F. J. Pardiñas : The monotypic rodent Mindomys Weksler, Percequillo & Voss, 2006 (Cricetidae, Sigmodontinae) is one of the rarest members of the speciose tribe Oryzomyini. As this species is restricted to the Chocó forests of the western Andean slope in northern Ecuador, our knowledge is based on a few specimens collected decades ago. Here we add the first data on some aspects of external anatomy (cheiridia examined in fresh, ears, rhinarium), genital anatomy (penis), soft anatomy (palate, stomach, caecum) and postcranial skeleton retrieved from a full adult male, recently trapped in Reserva Drácula, Carchi, Ecuador. Several features of this specimen, paradoxically the first to be added to Ecuadorian mammal collections, reinforce the view that Mindomys is an arboreal sigmodontine. HTML XML PDF

  • Phylogeography of the Central american red brocket deer, Mazama temama
           (Artiodactyla, Cervidae) in southeastern Mexico

    • Abstract: Neotropical Biology and Conservation 16(2): 369-382
      DOI : 10.3897/neotropical.16.e58110
      Authors : Ricardo Serna-Lagunes, Dayana Kristel Romero-Ramos, Christian Alejandro Delfín-Alfonso, Juan Salazar-Ortiz : Anthropogenic threats have increasingly isolated the populations of Mazama temama (Erxleben, 1777) and limited the gene flow in this species. Knowledge of the phylogeographic structure of this species is therefore essential for its conservation. Thus, in this study, we describe the phylogeographic structure of two M. temama populations of Veracruz and Oaxaca, Mexico. We sequenced the D-Loop region of the mitochondrial DNA of 16 individuals, in order to estimate the diversity and genetic differentiation (FST), Tajima’s D index, "Mismatch distribution" test; a phylogram and a haplotype network was constructed and we performed multidimensional scaling analysis to test the hypothesis of association between geographic distance and genetic diversity. The haplotypic and nucleotide diversity was high, indicating divergent populations (FST = 0.223), while the Tajima’s D index (-1,03300; P> 0.10) determined disequilibrium in the D-Loop region, derived from a population expansion that was evidenced in the "Mismatch distribution" test and confirmed with the haplotype network in the form of a star. Four lineages were identified in the phylogram (Veracruz n = 3, Oaxaca n = 1), evidencing geographic and reproductive isolation between the two populations. This was confirmed by the multidimensional scaling analysis, which evidenced recent evolutionary divergence between the populations analyzed, which are considered evolutionary units of conservation.

  • Medium and large-sized mammals in Private Natural Heritage Reserves in the
           Quadrilátero Ferrífero of Minas Gerais, Brazil

    • Abstract: Neotropical Biology and Conservation 16(2): 383-396
      DOI : 10.3897/neotropical.16.e62189
      Authors : Thales Claussem Vicente Corrêa, Lara Modesto Mendes, Kleiber José Vaz de Melo Barbosa, Fabiano Rodrigues de Melo : Habitat fragmentation has been shown to be constantly growing and increasingly affecting the conservation of species that require large areas for their populations to subsist, as is the case for most large animals. In Minas Gerais, there are 45 species threatened with extinction in the Brazilian Red List and for most mammal species there is not yet sufficient data on their populations and distributions, which makes it difficult to understand their conservation status. To understand the composition of medium and large mammals in two Private Natural Heritage Reserves (RPPNs) in the Quadrilátero Ferrífero of Minas Gerais (Cata Branca and Córrego Seco), in a transition zone between the Atlantic Forest and the Cerrado, a camera trapping survey of mastofauna was carried out between November 2019 and May 2020. The combined RPPNs have a rich diversity with 20 species of medium and large mammals and provide a fundamental service for the protection of animals threatened with extinction, in addition to harbouring important species for the maintenance of local ecosystems. However, they are areas with a strong anthropic impact and have a lower richness than some other reserves also located in the Quadrilátero Ferrífero, especially Cata Branca, which had a lower richness than Córrego Seco.

  • Success in conserving the bird diversity in tropical forests through
           private protected areas in Western Ecuador

    • Abstract: Neotropical Biology and Conservation 16(2): 351-367
      DOI : 10.3897/neotropical.16.e63414
      Authors : José Guerrero-Casado, José Manuel Seoane, Nikolay Aguirre, Jeronimo Torres-Porras : Private protected areas have recently attained more importance at a worldwide level as regards nature conservation. Particularly, the specific region of Western Ecuador receives hardly any protection from the State, and private reserves could, therefore, be a suitable tool to ensure the preservation of its forests and their associated wildlife biodiversity. In this work, we compare the bird species richness between private reserves and public protected areas (managed by the State) located in this region. We also show a checklist of bird species found in the Buenaventura Reserve, a private reserve located in south-western Ecuador. Our comparison shows that smaller private reserves may harbour a similar number of bird species than larger protected areas managed by the state, and they have a higher number of bird species per area. In particular, a total of 233 different bird species were registered in Buenaventura, which were distributed in 16 orders and 42 families. Three species were classified as endangered at an international level: El Oro Parakeet (Pyrrhura orcesi), El Oro Tapaculo (Scytalopus robbinsi), and the Grey-backed Hawk (Pseudastur occidentalis), and another three at a national level: the Long-wattled Umbrellabird (Cephalopterus penduliger), the Slaty-winged Foliage-gleaner (Philydor fuscipenne), and the White-vented Plumeleteer (Chalybura buffonii). Therefore, private reserves can be appreciated as a suitable conservation tool for bird conservation, and they should not be undervalued because of their smaller size. Buenaventura Reserve is a good example of how private reserves are extremely important in fragmented landscapes, as is the case with tropical forests in Western Ecuador. HTML XML PDF

  • Seasonal dynamics of waterbirds from a relict wetland in the central Monte
           Desert, Argentina

    • Abstract: Neotropical Biology and Conservation 16(2): 333-349
      DOI : 10.3897/neotropical.16.e61672
      Authors : Ever Tallei, Analía Benavidez, Alejandro Schaaf, Pablo Isola, Marcelo Zanotti : Wetlands currently have high rates of degradation, with more than 70% lost globally. In the central Monte Desert, Argentina, they are a scarce and limited resource for the biodiversity which depends on them. Waterbirds have been used as biological indicators of wetlands because they respond to fluctuations in food resources and to environmental changes in the short term. Here we analyse the seasonal variations in the structure of the waterbird assemblage from a relict wetland in this region. We carried out censuses of waterbirds in a 6-year period (between 2009 and 2019) during the southern summer and winter. We recorded 1875 individuals of 33 species of waterbirds during the summer and 677 individuals of 29 species during the winter. The grouping patterns of the waterbird assemblages differed between seasons (R = 0.35; p < 0.01). Taxonomic diversity profiles showed greater diversity for all indexes (qD) during the summer. The guild of invertivorous and omnivorous waders had a greater abundance of individuals during the summer (p < 0.05) and, together with the surface-feeding herbivores, contributed to the 87% of the dissimilarity of the assemblages between seasons. Phoenicopterus chilensis was the only species registered as threatened with national and international extinction. Relict wetlands, such as Laguna del Viborón, still have attributes of community diversity and represent the last refuges for waterbirds of the central Monte Desert. The information gathered in this study will contribute to the guidelines for integrated management plans and monitoring programmes for the conservation of the wetland and its biodiversity.

    • Abstract: Neotropical Biology and Conservation 16(2): 317-331
      DOI : 10.3897/neotropical.16.e57872
      Authors : Todd R. Lewis, Rowland K. Griffin, Irune Maguregui Martin, Alex Figueroa, Julie M. Ray, Josh Feltham, Paul B. C. Grant : Ecological and morphological data on Ungaliophis panamensis is extremely limited as this species is rarely encountered. These knowledge gaps have been advanced in this study where data was analysed from a small sample of snakes collected in two tropical forested environments in Costa Rica and Panama. Standardised major axis testing and a Bayesian latent variable ordination revealed that the species is sexually dimorphic, closely associated with tree trunks in natural forested areas, and occasionally discovered in rural buildings. Although further investigation into its natural history is warranted, this study shows that even with just a few individuals it is possible to elucidate ecological information that is relevant to the conservation of snake species.

  • Gauchergasilus euripedesi (Copepoda, Ergasilidae) parasitizing different
           species of fish from two environments in southern Brazil

    • Abstract: Neotropical Biology and Conservation 16(2): 289-298
      DOI : 10.3897/neotropical.16.e64668
      Authors : Moisés Gallas, Laura R. P. Utz : The parasitic copepod Gauchergasilus euripedesi (Montú, 1980) Montú & Boxshall, 2002 was described from plankton samples and specimens found in four fish species from the estuarine area of Patos Lagoon, state of Rio Grande do Sul (RS), Brazil. Later, one different fish species was reported parasitized with G. euripedesi in the same locality. Species of Astyanax Baird & Girard, 1854 (Astyanax henseli Melo & Buckup, 2006 and Astyanax lacustris (Lütken, 1875)) and Psalidodon Eigenmann, 1911 (Psalidodon eigenmanniorum (Cope, 1894) and Psalidodon aff. fasciatus (Cuvier, 1819)) were collected in two environments (Pintada Island, municipality of Porto Alegre and Itapeva Lagoon, municipality of Terra de Areia, RS) to investigate their parasites. The copepods found in the gill arches were counted, processed, mounted in permanent slides, and photographed using light microscopy, or processed for observation in scanning electron microscopy. Specimens of P. eigenmanniorum from Pintada Island, A. lacustris and P. aff. fasciatus from Itapeva Lagoon, were parasitized by G. euripedesi, with prevalences of 29.03% (A. lacustris), 10.34% (P. eigenmanniorum), and 9.68% (P. aff. fasciatus). Measurements obtained for specimens of G. euripedesi were similar to those found in the literature, except for egg sacs which were larger in the specimens examined in the present study. In addition to being the first report of G. euripedesi parasitizing species of fish (A. lacustris, P. eigenmanniorum, and P. aff. fasciatus), the results presented here also extend the known geographic distribution of the copepod species.

  • Nest site selection and nesting behavior of the mud turtle Kinosternon
           scorpiodes (Testudines, Kinosternidae) in Palo Verde National Park, Costa
           Rica: implications for management

    • Abstract: Neotropical Biology and Conservation 16(2): 273-287
      DOI : 10.3897/neotropical.16.e60754
      Authors : José M. Mora, Franklin E. Castañeda : Habitat selection is the process whereby individuals preferentially use, or occupy, a non-random set of available habitats. At the same time, nest site selection is defined as the placement of eggs by females at sites differing from random sites within a delimited area. We located 59 nests of the mud turtle Kinosternon scorpioides in Palo Verde National Park (PVNP) in Northwestern Costa Rica. We compared eight microhabitat variables at nest sites against those at random sites. Females significantly placed their eggs at sites with more understory, leaf litter cover, and greater leaf litter depth than in random sites. Additionally, females selected sites with lower air and soil temperature and lower air humidity. Palo Verde NP is subject to active management actions designed to control invasive plant species in the wetland, namely cattail (Thypha domingensis Pers.). The main actions have been cattle grazing, controlled fires, and mechanical crushing of vegetation. We found that habitat quality in nesting areas is being threatened by at least one of these actions: cattle grazing. This is detrimental for three microhabitat traits that turtles select for nesting sites: understory cover, leaf litter cover, and leaf litter depth. The continued degradation of microhabitats at nesting areas of K. scorpioides at PVNP could be affecting recruitment due to embryo survivorship. HTML XML PDF

  • Temporal edge effects structure the assemblages of Drosophilidae (Diptera)
           in a Restinga forest fragment in Southern Brazil

    • Abstract: Neotropical Biology and Conservation 16(2): 299-315
      DOI : 10.3897/neotropical.16.e61481
      Authors : Mayara Ferreira Mendes, Monica Laner Blauth, Luana Amaral Dos Santos, Vera Lúcia da Silva Valente Gaiesky, Marco Silva Gottschalk : Anthropogenic habitat fragmentation directly affects ecological processes, leading to negative biodiversity impacts for insects and other biota. Increased edge effects are one consequence of fragmentation, and may alter the composition or abundance of species in the remaining habitat fragments. Understanding the ways in which edge effects impact upon the biota is essential for conservation decision-making in fragmented landscapes. Therefore, the aim of this study was to analyze the seasonal patterns of abundance, richness, and composition of Drosophilidae in a Restinga forest fragment in the extreme south of Brazil, as a function of the distance from the edge to the interior of the fragment. The data were analyzed using SIMPER analyses, which showed that the edge and the forest interior were most dissimilar during winter, followed by spring, autumn and summer. An NMDS and the SIMPER analyses showed that the lower dissimilarity between the edge and interior in spring, autumn and summer, compared to winter, is driven by immigration of individuals from outside of the forest fragment. Furthermore, some species were asymmetrically distributed in the fragment, with some species restricted to the edge of the fragment and others to the interior. This information aids in the understanding of the functioning and dynamics of fragmentation, which is fundamental for the maintenance and integrity of environments and their fauna. HTML XML PDF

  • Structure of aquatic macroinvertebrate communities in streams of a
           sub-basin in the Pampa Biome, Southern Brazil

    • Abstract: Neotropical Biology and Conservation 16(2): 249-271
      DOI : 10.3897/neotropical.16.e60579
      Authors : Sirlei Maria Hentges, Tieli Cláudia Menzel, Cristiane Maria Loebens, Samuel Elias Siveris, David Augusto Reynalte-Tataje, Milton Norberto Strieder : The Piratinim River is located in the northwest of Rio Grande do Sul, and represents an important effluent from the Uruguay River, with streams located far from urbanized areas, in conditions similar to those of environmental integrity, but under the influence of agricultural activities. In this study, we aim at investigating the structure of the aquatic macroinvertebrate community in streams of the Piratinim river basin by observing both spatial and local scales. The sampling was carried out in six streams distributed in three regions (upper, middle and lower) of the basin, thus exploring its upstream, intermediate and downstream stretches, during spring and autumn. Macroinvertebrates were collected using aquatic dipnets and were identified at the family level; trophic-functional categories were established according to the classification adapted to the state of Paraná. The spatial and temporal variations of the groups and of the biotic attributes (density, richness, diversity and equitability) were subjected to Kruskal-Wallis non-parametric tests and a posteriori Dunn’s tests. The abiotic variables were obtained to verify possible influence on the composition of the macroinvertebrate community, evaluated through a Canonical Correspondence Analysis. We sampled 11,564 macroinvertebrate individuals from 72 taxa, and found a predominance of the collector-filter trophic group. Abundance and richness were different between streams; the highest densities were found in the streams located in the upper region of the watershed (Chuní and Itú). The highest taxon richness was found in the lower region of the watershed (Guaracapa stream), and the lowest richness was found in the two streams for the intermediate region (Santana and Ximbocu). Diversity and equitability did not vary; temporal variations were not found. Canonical correspondence analysis explained 31.7% of the data variability. The main environmental variables that influenced macroinvertebrates distribution were temperature, electrical conductivity, dissolved oxygen, altitude and extension of the riparian forest. Seasonality and the longitudinal gradient along the basin represented determining factors for the structure and distribution of the macroinvertebrate community in the tributary streams of the Piratinim River.

Remaining individuals inhabit mainly legally protected areas. Here we report the first records outside of conservation areas in the state of Santa Catarina, over the last 30 years. These records were found during a mammal monitoring program, developed between May 2018 and July 2020. The records provide new evidence of the distribution of the species in Santa Catarina and reinforce the relevance of connectivity between protected areas of the Serra do Mar Ecological Corridor.

      Authors : Erika Pereira Cordeiro de Melo, Juliana Simião-Ferreira, Herson Pereira Cordeiro de Melo, Bruno Spacek Godoy, Rodrigo Damasco Daud, Rogério Pereira Bastos, Daniel Paiva Silva : The increasing destruction of natural environments worldwide favored more and more alien species’ dispersal, distancing people from nature and consequently from native species. We investigated undergrad students’ perception about alien and native Brazilian species evaluating classes of the first (freshmen) and last semesters (seniors) of four courses in environmental sciences in three institutions and assessed these students’ knowledge level in different aspects related to native and alien species. The 509 interviewees were able to identify Brazilian native species better than alien species. They also produced better identifications among taxonomic groups of mammals (either alien or native), native birds, and exotic fish compared to invertebrate species. Most students did not consider themselves well informed about the topic. We found an association between the courses/semesters attended and the level of knowledge of the students. Thus, we concluded that, on the one hand, the students demonstrated relevant knowledge about the native species but, on the other, presented deficiencies in invasive alien species’ knowledge. Therefore, we suggest the revision/restructuring of how the biological invasions theme is covered in the academic curricula of undergraduate courses in the environmental area. HTML XML PDF

      Authors : Analía Benavídez, Ever Tallei, Echevarría Ada Lilian, Luis Rivera : Although there are studies on certain aspects of the feeding ecology of several species of Neotropical parrots, there is scarce ecological information about Pyrrhura molinae – a Psittacidae species which is widely distributed in South America and abundant in the Yungas of Argentina. For two years (May 2014 to June 2016), the composition and seasonal variation in the Green-cheeked Parakeet diet in the Yungas Piedmont forest in Jujuy, Argentina were examined. Furthermore, fruiting phenology transects were established to evaluate food resource availability and the patterns of food resource used by the Green-cheeked Parakeet. In 214 food plant trees, it was found that flower and dry fruit availability was highest in the dry season, and fleshy fruit production peaked in the wet season, but these phenology patterns for aged plant species suggest that there were no significant differences in food availability. The consumption of 18 plant species was recorded, being Celtis iguanaea (30.73%) and Trema micrantha (22.01%) the most consumed species. In terms of food items, fruits were the most consumed items, followed by seeds and flowers and, to a lesser extent, nectar and leaves. Levins’ niche breadth showed varying levels of diet specialisation amongst seasons, which was narrower (B = 0.28) in the wet season, indicating specialisation in diet during this season. There was a medium overlap in parakeet diet between seasons (Morisita Index = 0.59). We did not find a statistically significant relationship between resource availability and food use, but expansion and contraction in Levins Index and variation in food items consumed throughout the year and season demonstrate high flexibility in the diet. Like other congeners, the Green-cheeked Parakeet has a flexible diet that could be adjusted to the seasonal availability of food resources. These data may contribute to the design of conservation plans for the species and its habitat. HTML XML PDF

  • An annotated list of the reptiles of the highland grassland of Tandilia
           Mountains, Argentina

    • Abstract: Neotropical Biology and Conservation 16(1): 185-204
      DOI : 10.3897/neotropical.16.e60629
      Authors : David Gustavo Vera, Diego Omar Di Pietro, Germán Tettamanti, Manuel Eirin, Clara Trofino Falasco, María Florencia Aranguren, Jorge Daniel Williams, Federico Pablo Kacoliris, Igor Berkunsky : The study of biodiversity is a fundamental step to develop conservation strategies. Reptile populations are immersed in a global crisis, due to anthropic disturbances. Almost the entire Pampa ecoregion in Argentina was modified for agricultural and livestock activities, the only remnants of mountain native grasslands in Buenos Aires province being the Tandilia and Ventania mountain systems. Ventania reptiles have been exhaustively researched in last years, while Tandilia counts with fewer studies. We presented an actualized reptiles list of the Tandilia Mountain System. We used five data sources to collect presence records: literature, fieldwork, museum collection, citizen science, and a online database. The composition of reptiles from the Tandilia Mountain range includes 26 species in 12 families. Due to the presence of several endemic reptiles, and the representativeness of more than half of the reptiles of Pampa Ecoregion, Tandilia would be useful to determine conservation priority areas to conserve the native grassland and their reptile fauna.

  • Natural regeneration in a mixed ombrophilous forest remnant in southern
           Brazil

    • Abstract: Neotropical Biology and Conservation 16(1): 167-183
      DOI : 10.3897/neotropical.16.e58188
      Authors : Manuela Gazzoni dos Passos, Geisa Percio do Prado, Claudia Fontana, Edilvane Ines Zonta, Edmilson Bianchini : The study of forest regeneration allows the diagnosis of conservation status of fragments and estimating population parameters that are essential for management projects. This study evaluated the structure, diversity and dynamics of the tree regenerating component of a remnant of mixed ombrophilous forest, aiming to support management actions for this forest type. The study was developed at the Parque Estadual das Araucárias (PEAR), located in the western region of the state of Santa Catarina, southern Brazil. A total of 100 plots of 25 m2 (0.25 ha) were allocated, all individuals with height ≥ 1.0 m and DBH < 5 cm were sampled. Shannon’s diversity index (H’), Pielou’s equability index (J) and total natural regeneration rate (TNR) were estimated. We sampled 1,425 individuals from 99 species and 39 families, with an estimated total density of 5,700 individuals by hectare. The richest families were Fabaceae (13), Myrtaceae (10) and Lauraceae (7). The H’ was 3.76 and the J was 0.80. The TNR rate ranged from 0.05 to 8.12%, highlighting Trichilia elegans, with the highest rate and Araucaria angustifolia with low potential for natural regeneration. The analysis of the results indicated a high diversity in the regenerating component of the PEAR compared to other studies, probably because the area presents itself as a successional mosaic due to past disturbances.

  • Species richness, geographical affinities and activity patterns of mammals
           in premontane Andean forests of the Magdalena River basin of Colombia

    • Abstract: Neotropical Biology and Conservation 16(1): 145-166
      DOI : 10.3897/neotropical.16.e57109
      Authors : Diego A. Torres, Abel Eduardo Rojas : More than half of the population of Colombia is settled in the Magdalena River basin, resulting in high deforestation rates due to productive activities and urbanisation. Within this scenario of forest loss and ecosystem degradation, it is imperative to record and monitor the biodiversity in order to decrease and mitigate the negative consequences of human activities on species and ecosystems. For six years, we assessed the mammal species richness, abundance and activity patterns in premontane forests of the Magdalena River basin in the Department of Caldas, Colombia. We also presented additional information on the geographical affinities of this fauna. We recorded 101 species, seven of them endemic to Colombia, with Chiroptera being the richest order, followed by Rodentia. Most of the species are common and not listed in threatened categories and only four are vulnerable and two endangered, according to the Red List of the IUCN and the Ministerio de Medio Ambiente y Desarrollo Sostenible of Colombia. The mammalian fauna of the study area is similar to that of other lowland localities in the Neotropics and different to the fauna in highland localities, including the nearby ones. Specifically, this fauna was most similar to that in lowland Tolima and the Caribbean Region of Colombia, Venezuela and Costa Rica; however, when we accounted only for bat fauna, it was more similar to the fauna in Caribbean and Pacific Regions of Colombia. To secure the long-term persistence of these species, we recommend maintenance of the current corridors, such as riparian forests and living fences and an increase in the forested area. HTML XML PDF

  • Bird composition of different valley habitats after land-use changes in
           Northern Honduras

    • Abstract: Neotropical Biology and Conservation 16(1): 129-144
      DOI : 10.3897/neotropical.16.e57624
      Authors : Stefan Hohnwald : The northern coast of Honduras is potentially covered with tropical rainforests, reaching from the Caribbean Sea up to the cloud forests of the Pico Bonito summits. Therefore, it was blessed with the mega-diverse avifauna of the Central American humid neotropics. Although local bird species have been generally well documented, there are hardly any updates on the biodiversity of northern Honduras. Thus, this study contributes to our knowledge of the natural shift of bird life, following up the Cangrejal River with its different slight land use intensification in the region. Standardized bird records along the valley are analyzed, reaching from the beaches of La Ceiba up to the managed rainforests of El Toncontíns in the lower montane rainforests. Nine points were checked over the course of at least 6 days, taking point counts between 16 March and 20 June 2005. A NMDS of the joined nine point-lists elucidates four main groups, namely the beach/city ecosystems, open habitats along the river banks, slightly cleared forests (park landscape), and a mature rainforest. In total, 115 bird species, from 102 genera and 44 families, were found in 2005. As methods are limited, results can represent merely a prodromus of bird composition of neotropical valleys of the Central American isthmus. However, avi-diversity is affected by forest degradation and increasing land-use changes. Since deforestation is still soaring in the region, bird species composition should be monitored, as it will be as dynamic as land use changes in the region. HTML XML PDF

  • An update of the amazon prawn (Macrobrachium amazonicum) distribution in
           the low course of the São Francisco river (northeast Brazil)

    • Abstract: Neotropical Biology and Conservation 16(1): 105-114
      DOI : 10.3897/neotropical.16.e58895
      Authors : Lucia Vanessa Rocha Santos, Petrônio Alves Coelho Filho : The prawn Macrobrachium amazonicum has been considered a successful colonizing species of freshwater environments beyond its native range; however, information on the distribution of the species in rivers in northeastern Brazil is doubtful or incomplete. This study updates the presence of the Amazon River prawn Macrobrachium amazonicum in the São Francisco River (northeast Brazil) where eight areas were sampled downstream from the Xingó Hydroelectric Plant (Alagoas/Sergipe) up to the mouth of the river, between April 2014 and February 2016. The specimens were sampled using manual trawls and artisanal traps. Hydrological data were obtained using a multi-parameter probe. Only 258 specimens were found in Piranhas, Pão de Açúcar, and Belo Monte, which are regions far from the mouth of the river. They were found in shallow (3.96 ± 1.01 m), warm (26.15 ± 1.18 °C), and oxygenated fresh waters (5.70 ± 1.14 mg L-1) with low turbidity (71.33 ± 6.43 mg L-1) and slight alkalinity (7.26 ± 0.53), always associated with the aquatic vegetation. The presence of M. amazonicum has not yet been evaluated in relation to possible impacts on local native diversity. Therefore, studies addressing the interaction of this species with native species are necessary to understand whether or not it poses a risk to endemic species. HTML XML PDF

  • New records and conservation of Passiflora L. (Passifloraceae s.s.) in Rio
           de Janeiro, Brazil

    • Abstract: Neotropical Biology and Conservation 16(1): 115-128
      DOI : 10.3897/neotropical.16.e62045
      Authors : Michaele Alvim Milward-de-Azevedo, Natália Brandão Gonçalves Fernandes : Passiflora L. belongs to the family Passifloraceae sensu stricto, and comprises 700–750 species. There are approximately 161 known species of the family in Brazil, of which 153 belong to Passiflora, 89 are endemic, 83 occur in the region of the Atlantic Domain; 40 occur in Rio de Janeiro State (RJ). Using field samplings techniques and scientific collection analyses, we present here new geographic records for Passiflora deidamioides Harms, P. imbeana Sacco, P. junqueirae Imig & Cervi, and P. truncata Regel for RJ, principally in the Serra dos Órgãos National Park (PARNASO). Geographic distribution data was used to calculate the Extension of Occurrence (EOO) and Area of Occupancy (AOO) of the species. Passiflora junqueirae, previously considered endemic to Espírito Santo State, now has new records for RJ. Passiflora imbeana and P. truncata are extended into RJ, being recorded there for the first time in the municipality of Teresópolis. The four species are cited for the first time in PARNASO, occurring between 1,000 and 1,700 m.a.s.l. in Montane and Upper Montane Atlantic Rainforest. We provide taxonomic information, distribution maps, and the conservation status of the species. HTML XML PDF

  • Invasive alien plants in Sergipe, north-eastern Brazil

    • Abstract: Neotropical Biology and Conservation 16(1): 89-104
      DOI : 10.3897/neotropical.16.e56427
      Authors : Juliano Ricardo Fabricante, Kelianne Carolina Targino de Araújo, Thieres Santos Almeida, João Paulo Bispo Santos, Daniel Oliveira Reis : Biological invasions are considered one of the greatest threats to global biodiversity. In addition, they cause substantial economic impacts. However, studies about the subject in Brazil are still scarce. The aim of the present study was to prepare an inventory of non-native flora with invasive potential from Sergipe, Brazil. The inventory was carried out along the entire length of the sites. The species with potential invaders were grouped according to the biome/ecosystem and classified according to their habit and origin. Eighty-five species with invasive potential were sampled, 43 in the Caatinga, 75 in the Atlantic Forest, 36 in Sandbank and 22 in Mangrove. From these species, 17 were inventoried in all the biomes/ecosystems and 36 were observed in only one of them, six in the Caatinga, 27 in the Atlantic Forest and three in Sandbank. The number of potentially-invasive species sampled in Sergipe is alarming. The present study showed nearly twice the species listed by other authors for the entire northeast Brazil. This high number of taxa may be a consequence of facilitating the transfer of these species and the conservation conditions of the ecosystems studied in Sergipe. Another very worrying factor is that many of the species sampled are extremely aggressive and cause a series of impacts. HTML XML PDF

  • Current knowledge on biology, fishing and conservation of the blue shark
           (Prionace glauca)

    • Abstract: Neotropical Biology and Conservation 16(1): 71-88
      DOI : 10.3897/neotropical.16.e58691
      Authors : Thaísy Emmanuelle Florentino da Silva, Rosangela Lessa, Francisco Marcante Santana : The blue shark (Prionace glauca) is a large predator in marine ecosystems, figuring as the most common and abundant species in oceanic fisheries. For this reason, many studies on this species were conducted throughout its entire distribution range. However, no comparison has been made regarding the variability of the aspects addressed herein. Thus, the present study aims at analyzing the available information on P. glauca. This species constitutes between 85 and 90% of the total elasmobranchs caught by oceanic fisheries with pelagic longlines. Growth parameters reveal that individuals in the Atlantic Ocean show the highest asymptotic lengths when compared to those found in other oceans. Females present an average uterine fecundity of 30 embryos. Although it shows a diverse diet, it is mainly composed of teleost fish and cephalopods. Currently, the main threat to the species is commercial fishing, being listed in Brazil and worldwide, according to IUCN as Near Threatened. Regardless, information on crucial aspects, such as its population dynamics, are still scarce or unreliable for many areas. Despite the number of studies regarding its distribution, abundance, and biology, data for new stock assessments of P. glauca are still needed to improve the species’ management. HTML XML PDF

  • Influence of environmental and morphological parameters on the microfauna
           community present in phytotelmata of a bromeliad in a fragment of Atlantic
           Forest, southern Brazil

    • Abstract: Neotropical Biology and Conservation 16(1): 59-70
      DOI : 10.3897/neotropical.16.e56186
      Authors : Débora Alessandra Antonetti, Eduardo Malfatti, Laura Roberta Pinto Utz : Bromeliads are important epiphytes due to their abundance in the Neotropical region and morphological complexity. Their compact and imbricated leaf bases form water storage cisterns that promote important resources for colonization by several prokaryotic and eukaryotic microorganisms. Due to the lack of knowledge about these environments, the objective of the study was to investigate which physical-chemical and ecological parameters exert effects on the biological richness present in the cisterns of Vriesea platynema. The study was carried out in the Center for Research and Nature Conservation (CPCN – Pró-Mata), in the Serra Geral plateau, northeastern Rio Grande do Sul, Brazil. Active searches were performed for 10 trees with bromeliads fixed at two heights (< 1.5 m and > 2.5 m). For each bromeliad individual, the height in relation to the ground, the diameter and depth of the central cistern, water temperature, number of lateral cisterns and number of adjacent bromeliads, were measured. A total of 23 taxa were identified in the phytotelmata of V. platynema, with Philodina, Lambornella, Paramecium, Tetrahymena and Diptera larvae being the most representative groups. The richness of organisms in the phytotelmata presented a positive correlation with water temperature (p = 0.01), and the number of adjacent bromeliads (p = 0.05), indicating that physicochemical and ecological factors could influence the richness of bromeliad biota.

  • Arinosaster patriciae (Porifera, Demospongiae): new genus and species and
           the second record of a cave freshwater sponge from Brazil

    • Abstract: Neotropical Biology and Conservation 16(1): 45-57
      DOI : 10.3897/neotropical.16.e50156
      Authors : Cecília Volkmer-Ribeiro, Maria da Conceição Tavares-Frigo, Alexandre Cunha Ribeiro, Maria Elina Bichuette : Arinosaster patriciae gen. nov. et sp. nov. is the second continental sponge registered for a subterranean environment (cave habitat) in Brazil and the Neotropical Region. The sponges were recorded and collected in a 5m depth technical dive in a sinkhole of Rio Claro, tributary of Rio Arinos, Tapajós system, Amazon Basin (-13.8170386, -56.6914225) at the locality of Sumidouro do Rio Claro, Municipality of Diamantino, state of Mato Grosso, central western Brazil. The cave is placed in sandstone rocks of the Parecis Group (Upper Cretaceous). “In situ” photographs of colonies, of living specimens, SEM illustrations of dissociated spicules as well as of the skeletal structure, are presented. The occurrence of euaster microscleres of the type spherasters are for the first time reported for continental sponges but, also new, is the occurrence of spongin fibers, composing with fibers of silicious spicules in the skeletal arrangement. The absence of gemmules in the studied material and the fact that new specimens remain undetected call for the proposition of a new monospecific genus to be retained as Incertae Sedis until new and gemmuliferous colonies are found.

  • Movement distances for four small mammals in two Atlantic forests
           fragments, Southern Brazil

    • Abstract: Neotropical Biology and Conservation 16(1): 11-18
      DOI : 10.3897/neotropical.16.e59669
      Authors : Daniela Oliveira de Lima, Luana Gabriele Arenhart Braun, Fabrício Luiz Skupien, Daniele Pereira Rodrigues, Jady de Oliveira Sausen : Animal movement has an important role in individual performance, species reproduction, population demography, and conservation, especially in fragmented landscapes. The distance moved by an individual may vary depending on individual needs, such as the search for food resources and sexual partners. Here we investigated which factors affect the distances between successive captures (hereafter DSC) for Akodon montensis, Oligoryzomys nigripes, Sooretamys angouya, and Didelphis albiventris. This study was conducted from April 2015 to October 2016 in two fragments in the south of Atlantic Forest biome through capture, mark and recapture technique. DSC was analyzed using Generalized Linear Models with Poisson distribution where the independent variables were sex, whether the animal was active or not in terms of reproduction, body weight, and climatic season. The mean DSC was greater for D. albiventris (44.6 ± 28.8 m), followed by S. angouya (31.9 ± 25.7 m), O. nigripes (25.8 ± 22.5 m) and A. montensis (18.9 ± 22.0 m). Males of all species moved larger DSC than females. Considering the rodents, reproductive animals also moved larger DSC than non-reproductive animals. Sex may have masked the effect of body weight, as males tend to be larger than females. Climatic effects were tested for A. montensis and O. nigripes, however, with diverse effects. HTML XML PDF

  • New records of mammals of the Coffee Region, Central Andes of Colombia
           using citizen science

    • Abstract: Neotropical Biology and Conservation 16(1): 27-43
      DOI : 10.3897/neotropical.16.e57932
      Authors : Sofía Terán-Sánchez, Alejandra Díaz-Arango, Héctor Fabio Arias-Monsalve, Héctor E. Ramírez-Chaves : The Coffee Region of Colombia is one of the most representative areas of the country due to its cultural appeal. 200 of the 528 mammal species in the country occur in this region. Pre-existing knowledge about the group in this region has been obtained through indirect and direct sampling methods. We present new records of mammals of the “Reserva Forestal Protectora Bosques de la Central Hidroeléctrica de Caldas (CHEC)”, located in the Coffee Region, based on vouchered citizen science records. To accomplish this, we held training workshops on the relevance of information provided by non-invasive vouchers for mammal collections that include bone remains, hairs, skin and other signs that can be found incidentally in the field by park rangers and other staff of the Reserve. In addition, we included photographic and video records of mammals taken by park rangers before and after the training workshops. We added vouchers obtained by the park rangers to the biological collection of the Natural History Museum of the Universidad de Caldas (MHN-UCa). Using this method, we obtained records of 34 mammalian species belonging to 20 families and 11 orders. We highlight the obtention of museum preserved vouchers of the Northern Naked-tailed Armadillo, Cabassous centralis (Miller 1899), and the Cauca Slender Opossum, Marmosops caucae (Thomas 1900), that had limited samples in national collections or had not been previously collected in the study area. With this work, a contribution network with the CHEC reserve staff was established, promoting the inclusion of these agents in the development of scientific research, and showing the relevance of collaborative science in assisting with filling information gaps about medium and large mammals.

  • What’s on the menu' A presumed attack of Andean bear on a Mountain
           tapir at the Puracé National Natural Park, Colombia

    • Abstract: Neotropical Biology and Conservation 16(1): 19-25
      DOI : 10.3897/neotropical.16.e57140
      Authors : Gustavo Adolfo Pisso-Florez, Ignacio Gómez-Lora, I. Mauricio Vela-Vargas, Héctor Pizo, Isaac Bedoya Dorado, Héctor E. Ramírez-Chaves : Two iconic and charismatic species that inhabit the northern Andes of South America are the Andean bear (Tremarctos ornatus) and the Mountain tapir (Tapirus pinchaque). Both species can be found sympatrically in several areas of Colombia, Ecuador, and northern Peru. Despite their overlap in distribution, little is known about interactions between both species, with few reported cases of Andean bear attacks on the Mountain tapir. Here, we report a possible attack by an Andean bear on a Mountain tapir in the northern part of Puracé National Natural Park, Colombia based on strong wounds and marks on a tapir’s back and rump. The wounds match typical attack patterns generated by Andean bears and corroborates previous camera traps records of bears attacking tapirs in this locality. HTML XML PDF

  • Bird activity patterns in the understorey of an evergreen forest in
           Oaxaca, Mexico

    • Abstract: Neotropical Biology and Conservation 16(1): 1-10
      DOI : 10.3897/neotropical.16.e59360
      Authors : Gabriela Pérez-Irineo, Antonio Santos-Moreno : Activity patterns of species are related to their physiology, their behaviour and the environment and can change in response to different factors, such as interactions between species. Bird species, typical of the understorey, show morphological and ecological similarities and must thus have some mechanism of ecological separation, such as temporal niche partitioning. The objective of this study was to provide information about activity patterns and activity overlap of bird species typical of the understorey. We expected temporal niche partitioning between ecologically-similar species. We placed camera traps in 29 sampling points in a high evergreen forest in the southeast of Mexico between 2011 and 2013. All species were mainly diurnal and, contrary to what we expected, there was temporal partitioning between tinamids, but not in galliforms and columbiforms. The degree of activity overlap might reflect a solitary or group lifestyle of the three sets of species, as well as shared behavioural preferences and similar adaptations. These results contribute to our knowledge of the basic biology and behavioural ecology of birds of the understorey. HTML XML PDF
