  • Dung Beetle Diversity and Community Composition Along a Land Use Gradient
           in a Savannah Ecosystem of North Western Tanzania

    • Authors: Roisin Stanbrook, John Norrey, Alex Wilbard Kisingo, Martin Jones
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      Habitat loss and degradation are the most widely cited drivers of changes in species abundance and diversity. We explored changes in dung beetle species diversity and composition across different land uses in the north west Tanzanian savannah. We expected a negative response gradient in the diversity and composition of the dung beetle community, from land uses that preserve vegetation and hold native mammal diversity to livestock intensive and heavily grazed areas. Dung beetles were sampled in a protected area and two anthropogenically influenced land use types. Species richness and composition of each land use type, including differences in diversity and functional groups were analyzed and indicator species for each land use gradient were identified. As expected, diversity and community composition varied between areas with less environmental change compared to those impacted anthropogenically. We conclude that conservation of protected areas within African savannahs can provide a functionally rich dung beetle community and subsequently rich ecological functions. The dung beetle species identified by this study as eco-indicators can be used as a benchmark for future studies that use rapid monitoring to assess disturbance in African savannas.

  • The Role of Media During COVID-19 Global Outbreak: A Conservation
           Perspective

    • Authors: Gugulethu Tarakini, Tongayi Mwedzi, Tatenda Manyuchi, Tawanda Tarakini
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      The COVID-19 pandemic is fast driving the ways of life and economies. In this study, we used Zimbabwe as a case study to assess how different forms of media are being utilised to access information of the COVID-19 disease (across age, educational level, and employment status). We investigated people’s perceptions of the origins of COVID-19, its implication on the continued consumption of meat from wildlife species by humans, and management strategies of wildlife species that harbour the coronavirus. We gathered 139 responses using an online structured questionnaire survey. Social media platforms were used to acquire information on the COVID-19 pandemic when compared to traditional sources (television, radio, and newspapers). Most respondents thought that the COVID-19 virus was created by humans (n = 55, mostly the young and middle-aged) while others believed that it originated from animals (n = 54, mostly middle-aged with postgraduate qualifications). The majority (73%) of respondents who cited COVID-19 origin as animals also supported a ban on consumption of meat from the species. The middle-aged respondents (in comparison to the young and older respondents) and those who were employed (compared to the unemployed) were more likely to support the ban in wildlife trade. The likelihood of visiting wildlife centres given the consequences of COVID-19 was significantly lower in the old-aged respondents when compared to the young and the middle-aged respondents. Our results emphasize the need for science to penetrate social media circles to provide appropriate information. The observed perceptions about visiting wildlife centres could negatively impact conservation funding.

  • Desiccation of Wetlands and Their Influence on the Regional Climate. Case
           Study: Ciénaga de Aguablanca, Cali, Colombia

    • Authors: Camilo Ocampo-Marulanda, Yesid Carvajal-Escobar, Aceneth Perafán-Cabrera, Lina María Restrepo-Jiménez
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      The desiccation of wetlands is a process associated with the dynamics of urban growth and expansion of the agricultural frontier. This article aims to evaluate the influence of the desiccation of the Ciénaga de Aguablanca on regional climate. The periodization of the desiccation and urban growth of Cali was reconstructed under the theoretical contributions of environmental history. As complementary sources, maps, aerial photographs, and diagrams of the city were obtained from 1944 to 2020, with which the hydromorphological changes in the Ciénaga de Aguablanca were represented. Data from six hydroclimatological stations were statistically analyzed with Pettitt’s test, trend analysis, and Rclimdex. The results indicate a reduction of 99% in the area of the wetlands, from 19.2 km2 in 1944 to 0.2 km2 by 2020. Additionally, a break point was observed in 1970, preceded by the process of wetland desiccation and waterproofing of the eastern part of Cali, along with significant differences between temperature series inside and outside the urban perimeter. Another break point was detected in 1985 in the flow series, associated with the construction of the La Salvajina dam. Monthly rainfall showed a tendency to increase, but its temporal distribution was uneven, given that rainfall volume showed a tendency to increase over short times. Regional climate changes can occur at a much faster rate than global variations due to the anthropogenic actions of wetland intervention.

  • The Importance of Forest-Nonforest Transition Zones for Avian Conservation
           in a Vegetation Disturbance Gradient in the Northern Neotropics

    • Authors: Dallas R. Levey, Alejandro Estrada, Paula L. Enríquez, Adolfo G. Navarro-Sigüenza
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      Tropical landscape connectivity and matrix quality near large stands of primary forest are important factors that dictate biodiversity trends in communities. Suitable matrix management surrounding primary forest may help conserve biodiversity, but areas with poor matrix management need attention to determine their long-term viability to support native levels of biodiversity. We examined variations in species and functional diversity and community composition using point-count surveys placed in preserved (PRES), transition (TRA), and disturbed (DIS) areas according to percent land cover of forest and cattle pasture along a human disturbance gradient in the northern Neotropics during an 8 month period from 2019–2020. We expected the gradient of human disturbance to drive species diversity loss of forest specialists from PRES to DIS, resulting in changes to functional diversity and community composition. We detected 228 species overall, with 163 in PRES (40 unique species), 159 in TRA (9 unique species), and 152 in DIS (20 unique species). TRA supported an avian community with shared aspects of PRES and DIS, leading to the highest functional, Shannon (85.8 estimated species), and Simpson (57.9 estimated species) diversity. Higher diversity of open-area specialists in TRA and DIS has led to shifts in functional traits and different species and functional community compositions relative to PRES. Land management in Neotropical human-modified landscapes must focus on increasing habitat quality in remnant forest fragments in the vicinity of large stands of primary forest to prevent species and ecosystem service loss from preserved areas and the distancing of local community compositions.

  • Evaluation on the Meteorological Service for Mitigating the Severe Impacts
           of Typhoon Rammasun

    • Authors: Yingjie Liu, Bingwei Cui, William D. Batchelor, Chengyi Zhang
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      This study takes the meteorological service of super typhoon Rammasun as an example, and proposes a multi-dimensional quantitative assessment method for meteorological service. Rammasun was the strongest typhoon that landed in China from 1949 to 2019. It hit the coastal areas of China three times, with a rare landing intensity in history. Guangdong, Guangxi, Hainan, Yunnan and other provinces have suffered disasters of varying degrees, with a total affected population of 12.084 million and a direct economic loss of 44.89 billion CNY. During this period, the total investment in meteorological services was approximately 1.213 billion CNY, and the economic benefits of disaster prevention and mitigation in the four disaster-stricken provinces were worth 16.1 billion CNY. According to the cost-benefit analysis of economics, the input-output ratio for disaster prevention and mitigation in Typhoon Rammasun was 1:13.

  • Relationship Between Genetic Variation and Diversity of Tree Species in
           Tropical Forests in the El Ocote Biosphere Reserve, Chiapas, Mexico

    • Authors: Bárbara Cruz-Salazar, Lorena Ruiz-Montoya, Neptalí Ramírez-Marcial, Maricela García-Bautista
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      Knowledge of the genetic diversity of species in a biological community is useful for assessing the ecological and evolutionary processes that define the structure and dynamics of that community. We investigated the potential relationship between the trans-specific genetic diversity (or genetic diversity across tree species) and the diversity of tree species in a tropical subdeciduous forest. The nucleotide variation of the concatenated regions ITS 1 and ITS 3 (ITS1-3) was used to determine the trans-specific genetic diversity of 19 species of trees in five local communities at El Ocote Biosphere Reserve (REBISO), Chiapas, Mexico. Tree diversity was obtained by counting individual trees within 0.1 ha circular plots in each locality. The relationship between trans-specific genetic diversity and species diversity was established through simple linear regressions between genetic diversity parameters and community diversity. A correlation matrix was built with genetic distances (Kimura’s two-parameter model) and differences in species diversity between communities. A significant relationship was observed between nucleotide diversity (π) and species richness (Sp), and a negative association between haplotype diversity and gamma diversity (γ). Our results show species-rich and genetically diverse tree communities and a weak association between trans-specific genetic variation and species diversity in tree communities at REBISO. This research suggests a possible ecological and genetic relationship within each community. Genetic diversity values may provide an important degree of variation upon which environmental selection pressures could operate, which may be helpful to face the current environmental modifications associated with climatic change.

  • The Use and Prescription of Pangolin in Traditional Vietnamese Medicine

    • Authors: Rebecca Sexton, Trang Nguyen, David L. Roberts
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      It is now acknowledged that demand stemming from traditional medicine stimulates a continued market for illegal wildlife trade globally. Increasing demand for pangolin fuels widespread unsustainable extraction and an illicit international trade that is threatening pangolin populations worldwide. Vietnam is an important transit country in this trafficking network and a significant consumer country, particularly due to their longstanding tradition of consuming wildlife products as traditional medicine. We conducted 51 semi-structured, questionnaire-based interviews with traditional Vietnamese medicine practitioners in Hanoi, Vietnam to explore the factors influencing their prescription of pangolin. The results show that traditional Vietnamese medicine practitioners are important drivers of pangolin use and that prescription continues despite prohibitive legislation. The main influencing factors were money, illegality (as a deterrent) and supply. Wealthier patients were more likely to use pangolin as medicine and patients generally trusted a doctor’s prescription. Awareness of regulations related to pangolin use in traditional medicine was low and pangolin use continued without fear of the law. Lactation, abscesses and circulation were the most prescribed uses for pangolin scales. All respondents believed that pangolin can be substituted, however, a belief remained that substitutes are inferior to pangolin. This study provides a unique perspective of pangolin use in one of the main pangolin consumption countries in the world. The results suggest that the law is not being implemented effectively and that increased enforcement efforts are necessary. Furthermore, these insights serve to inform future demand-reduction campaigns whereby the most common uses and substitutes for pangolin scales may be targeted.

  • Tree Species Diversity, Composition and Aboveground Biomass Across Dry
           Forest Land-Cover Types in Coastal Ecuador

    • Authors: Xavier Haro-Carrión, Bette Loiselle, Francis E. Putz
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      Tropical dry forests (TDF) are highly threatened ecosystems that are often fragmented due to land-cover change. Using plot inventories, we analyzed tree species diversity, community composition and aboveground biomass patterns across mature (MF) and secondary forests of about 25 years since cattle ranching ceased (SF), 10–20-year-old plantations (PL), and pastures in a TDF landscape in Ecuador. Tree diversity was highest in MF followed by SF, pastures and PL, but many endemic and endangered species occurred in both MF and SF, which demonstrates the importance of SF for species conservation. Stem density was higher in PL, followed by SF, MF and pastures. Community composition differed between MF and SF due to the presence of different specialist species. Some SF specialists also occurred in pastures, and all species found in pastures were also recorded in SF indicating a resemblance between these two land-cover types even after 25 years of succession. Aboveground biomass was highest in MF, but SF and Tectona grandis PL exhibited similar numbers followed by Schizolobium parahyba PL, Ochroma pyramidale PL and pastures. These findings indicate that although species-poor, some PL equal or surpass SF in aboveground biomass, which highlights the critical importance of incorporating biodiversity, among other ecosystem services, to carbon sequestration initiatives. This research contributes to understanding biodiversity conservation across a mosaic of land-cover types in a TDF landscape.

  • Malignant Snare Traps Threaten an Irreplaceable Megafauna Community

    • Authors: Joe J. Figel, Muhammad Hambal, Ivan Krisna, Rudi Putra, Dedi Yansyah
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      Tropical forests are under severe threat from over-hunting. Subsistence harvests and poaching have decimated wildlife populations to the extent that nearly 50% of Earth’s tropical forests are partially or fully devoid of large mammals. Declines are particularly acute in Southeast Asia where ongoing defaunation, largely attributable to indiscriminate snare trapping, is widespread. Using the extensively forested Aceh province in northern Sumatra as a case study, we document rampant snaring, which threatens Earth’s last sympatric population of tigers, rhinoceros, elephants, and orangutans. To prevent catastrophic hunting-induced impacts already experienced in mainland Southeast Asia, we call for more comprehensive conservation planning assessments that strengthen wildlife law enforcement, promote collaborative anti-poaching, and research species-specific snaring impacts, particularly in the context of human-wildlife conflict. We conclude with a discussion of the important linkages between poaching, wildlife trade, and zoonotic disease risk.

  • Effects of In Situ Burial and Sub-Optimal Storage on Seed Longevity and
           Reserve Resources in Sub-Tropical Mountain Cloud Forest Tree Species of
           Mexico

    • Authors: Candelaria Garcias-Morales, Alma Orozco-Segovia, Diana Soriano, Susana Zuloaga-Aguilar
      Abstract: Tropical Conservation Science, Volume 14, Issue , January-December 2021.
      To design conservation and management strategies for sub-tropical moist forests, it is important to know how storage affects the longevity and germination of desiccation-sensitive seeds. These variables are controlled by a physiological process that is mainly associated with the seeds’ moisture content and reserve content, which can be significantly affected by environmental conditions. The objectives of this study were: (i) to evaluate the relationship between longevity and reserve content of sensitive and non-sensitive desiccation seeds (ii), and to describe how the in situ burial and sub-optimal storage (inside growth chambers) can affect seed longevity. In seeds of six mountain cloud forest tree species, germination and seed reserve content were quantified in seeds collected recently (control) and at five different times, along with storage for 31 or 35 days in situ and under suboptimal conditions. Freshly harvested seeds with higher soluble carbohydrate and lipid content and the presence of thermo-stable proteins had the longest-expected ecological longevity and mean germination time. In contrast to in situ burial, germination was negatively affected by storage time. Burial time significantly affected the rate and mean germination time in most of the species. For two species, a greater soluble carbohydrate or a lower starch and lipid content in seeds was found to be related to the high germination rate in storage. Our results show that the sub-optimal storage reduces the lifespan in most of the study species and increases seed damages through dehydration.
