  • Grassland degradation and restoration: a conceptual framework of stages

      Land degradation is a complex concept that integrates different aspects, including changes in soil conditions, biodiversity, productivity and socio-economic implications, compared to a reference state. We propose a new conceptual framework to analyze degradation stages and restoration thresholds in species-rich natural grasslands. The framework integrates different degradation stages with their respective thresholds and describes key processes of land-use change that lead to certain stages and thresholds. Specifically, we discuss two scenarios of grassland degradation, i.e. unsuitable grassland management and complete change of land use, sometimes followed by spontaneous recovery. We illustrate the framework with the case of south Brazilian grasslands, which are rich in biodiversity, but suffer from a series of degradation processes and are poorly considered from a conservation perspective. The conceptual framework can be applied by studies on degradation and restorability of tropical and subtropical grasslands after changes in management or transition to other land use; it will facilitate decisions on alternative management and conservation.

  • The ecosystem service approach and its application as a tool for
           integrated coastal management

      Ecosystem services are the benefits that natural environments supply to human beings. Due to the immense diversity of ecosystems and objectives for which their services are being assessed, there are no standard methodologies for this type of evaluation. The high biodiversity and geodiversity of the coastal zone allow a wide range of services. However, deleterious impacts to the environment threaten the delivery of these services and, consequently, the human well-being they lead to. The coastal zone, with its multiple users and impacts, is a case in which an ecosystem-based approach would bring many benefits within the scope of an integrated coastal management strategy. By considering the ecosystem services supplied by the coastal zone, it is possible to make well-informed decisions. The objective of the present study was to carry out a revision on ecosystem services and their application within the context of coastal management.

  • Functional diversity: an overview of its history and applicability

      Ecological investigations are increasingly using functional diversity in order to understand different patterns, such as species occurrence, species competitive abilities, and the influence of biological communities on ecosystem functioning. Here we provide an overview of the history and applicability of functional diversity in ecological studies. We found that the idea of functional diversity emerged many times and in distinct fields over the years. Functional diversity was conceived as an alternative classification to measure the ecological importance of species in a community, as well as a way to understand how biodiversity affects specific ecosystem functions. Gradually, new questions regarding functional traits emerged. Some examples include understanding species competitive abilities, patterns of species co-occurrence, community assembly, and the role of different traits on ecosystem functioning. The increasing use of functional-based approaches fueled the search for new metrics aiming at accurately estimating functional diversity and, consequently, categorical-based classifications of functional traits have been gradually replaced by continuous multi-trait approaches. More recently, the role of functional diversity was recognized as a key factor to maintain important functions and services of ecosystems. We present empirical evidence supporting this statement.

  • Another blown in the wind: bats and the licensing of wind farms in Brazil

    • Authors: Rebeca Beltrão Valença; Enrico Bernard

      Brazil is the third largest market for new investments in wind power in the world and thousands of turbines will become operational in the coming years. Wind power is necessary but, as any other source of energy, it has environmental impacts, especially on bats. Due to such rapid expansion and the volume of investiments on course, an analysis of the current environmental licensing of wind farms in Brazil is necessary. Here we compared normatives from Brazil with similar ones from Portugal, the United States and Canada. By using 21 driving questions, we detected that there is no an international standard in the licensing of wind farms, ranging from simplified to rigorous approaches, from mandatory to voluntary normatives. Despite having specific and mandatory legislation dated from 2014, Brazil's federal and state normatives have a vague and relaxed approach regarding the possible impacts of wind farms on bats. Larger wind parks can be fractioned in smaller units, licensed based on simplified and less rigorous studies, but with no explanation on how or when such fractionating may occur, neither details on when adopt it. Only Brazilian legislations do not clearly specify the procedures and the minimum necessary effort for pre and post-installation, and which should be the mitigation measures adopted for the impacts of wind farms. The Brazilian federal and state normatives must be revised and until that, the current EIA procedures should be seen as insufficient to accurately determine the real impact of wind farms on the Brazilian bat fauna.

      In Brazil, the introduction of non-native fish is commonplace, and the only existing measure to address this problem is the normative approach (i.e., laws and inspections). However, this approach has failed to control or prevent introductions because enforcing laws in a country the size of a continent, where inspections and monitoring are minimal or non-existent, is difficult. In addition, society is generally unaware of this issue. More effective actions or complementary preventive measures are urgently needed, and the most promising approach is to change human behavior via educational opportunities. In this short essay, we propose that exposing society to high quality information is a powerful alternative because well-informed people naturally make more rational and balanced decisions. For example, informed stakeholders may be more cautious when handling non-native species, may adopt appropriate management practices and may cease deliberate releases. Moreover, a well-informed society will naturally avoid or prevent harmful activities that may lead to the introduction of alien species. From this perspective, this short essay explores opportunities to implement educational practices for containing new introductions. First, we present the primary activities that are responsible for the introduction of non-native fish in Brazil (i.e., aquaculture, fishkeeping and sport fishing) and then suggest simple educational pathways that are specific to each activity. In addition, we advocate for the inclusion of invasion biology in formal education to educate society as a whole. If the topic receives the necessary attention in the educational curriculum, then education will play a central role in creating new behavioral standards, awareness and responsibility at different societal levels, with the primary goal of reducing the rate of new fish introductions.

      Different causal mechanisms have been suggested to explain species decline in fragmented landscapes, mainly those related with the amount and configuration of habitat for species (habitat availability), and those related with the habitat patch quality. Here we quantify the effects of habitat availability and quality on the abundance of three small mammals in a landscape at the Brazilian Atlantic Forest. We compared species with different habitat preferences and dispersal abilities (Nectomys squamipes, Marmosa paraguayana and Didelphis aurita). The most sensitivity species to fragmentation (N. squamipes) was affected by habitat quality variables only, while the least sensitive species (D. aurita) did not suffer any effect of habitat quality and availability. M. paraguayana, a species with an intermediate degree of sensitivity, responded to both habitat quality and availability. We recommend combining information on both habitat availability and quality to unravel species persistence in fragmented landscapes.

      Species response to land-use changes are usually assessed by investigating factors affecting distribution, with a single snapshot in time. However, several processes can lead to a same pattern. Focusing on observed, short-term patterns limits our ability to make inferences about ecological processes and responses to environmental change over time. In this study, we assessed changes in occupancy of two primate species in southeastern Brazil, following a major habitat loss due to implementation of a hydroelectric dam. Occupancy was assessed before dam construction and 11 years after, while explicitly accounting for imperfect detection. We assessed the effect of forest patch size and isolation on occupancy and rates of extinction and colonization, driven by landscape modification. Then we calculated occupancy under metapopulation equilibrium and expected time-lags resulting from non-equilibrium. We compared two primate species inhabiting forest patches, the black penciled marmoset Callithrix penicilatta and the black-fronted titi monkey Callicebus nigrifrons, with markedly different ecological characteristics. Those differences may explain why occupancy dynamics were driven by distinct elements. A fast response to habitat changes was observed only for marmoset, an opportunistic species. However, non-equilibrium states and the possibility of time-lag effects were observed for titi monkey, a species dependent on forest habitat. Our analyses support the need to establish long term monitoring and assess system vital rates over time. A single snapshot in time may lead to erroneous interpretations of a species response to habitat alteration.

      The protected areas are essential for the conservation of native biota. However, only the protected area establishment does not guarantee the persistence of threatened species. Here, we assessed the efficiency of the Cerrado protected areas in maintaining viable populations of giant anteater and analyzed the impact of roadkills. We used the software VORTEX to model the viability of giant anteater populations in 18 Cerrado protected areas. We evaluated the impact of roadkills through three mortality scenarios (2.5%, 5% and 10% of the initial population). Our results show that in the pessimistic scenario, only three protected areas are able to maintain viable populations of the giant anteater. In the optimistic scenario, 11 protected areas out of the 18 protected areas are capable of maintaining viable giant anteater populations in the next 100 years. Three protected areas are not able to maintain viable populations in any scenario. The roadkills have had a major negative impact on the long-term persistence of giant anteater populations. We suggest that management actions to counteract the negative effects of roadkills are necessary to maintain populations of giant anteater in protected areas affected by this threat.

      The third largest biodiversity hotspot of the world, Mesoamerican forests are declining due to human pressures. Based on species distribution models calibrated for 1224 native tree species in Mesoamerica, we identified high-value forest conservation areas (FCA) at the resolution of a 10km×10km cells using the Zonation Reserve Selection software, and investigated whether these FCAs cells are well represented by the World Database on Protected Areas (WDPA) network. We had three key findings. First, dry forest is the least protected biome in Mesoamerica (4.5% protected), indicating that further action to safeguard this biome is warranted. Secondly, the poor overlap between protected areas (PAs) and FCAs found herein may provide evidence that the establishment of PAs may not be fully accounting for tree priority rank map. Third, high percentages of forest cover and FCA still need to be represented by the PA network. Because deforestation rates are still increasing in this region, Mesoamerica needs funding and coordinated action by policy makers, national and local governmental and non-governmental organizations, conservationists and other stakeholders.

      Climate change is an important factor affecting species dispersal and distribution through time and the accelerated global warming has currently concerned decision makers and conservationists. Because protected areas are spatially static, species extinction risk is generally expected to increase under climate change scenarios as a consequence of range shift and decrease. This study aims to understand the current conservation status of Actinote quadra, a neotropical threatened butterfly species, as well as predict how it will be in the future. By coupling ecological niche modeling and climatic simulations, we predicted the species distribution in different future global warming scenarios (2050 and 2070) and estimated the proportion of species range overlapping protected areas through time. Our findings showed a generalized decrease of the potential distribution of A. quadra in the end of 21st century, with the most prominent range loss predicted to occur out of protected areas. Although climate change will potentially drive A. quadra into reserves, the predicted range collapse would be enough to increase its extinction risk from vulnerable, like currently categorized, to the status of critically endangered in accordance to IUCN red list criteria. Taking into account the fragmented and discontinuous landscapes across the Atlantic Forest's hotspot, we propose a conservation strategy for A. quadra based on potential ecological corridors linking climatically suitable areas and discuss the need for amplifying and connecting the current protected areas to maintain this threatened species at longer time under a global warming scenario.

      The relevant scales over which specific communities vary must be identified to address fundamental ecological questions and to advance the conservation of biological diversity. In this study, the variation among drosophilid assemblages associated with forests was quantified at a large temporal–spatial scale. Our results are based on data collected in four conservation units (CUs) in the Brazilian savanna across four seasons and two years. The primary component of variation occurred at the temporal scale: it was three times greater than that of the spatial scale. Significant variability was also found in the interaction between seasons and CUs. Measuring the temporal and spatial variability of drosophilid diversity in forests contributed to the improvement of the methodological framework supporting such assemblages as bioindicators and provided important insights into the mechanisms behind the dynamic patterns in time and space that ultimately can improve our understanding of Cerrado biodiversity.

      Miscanthus sinensis-dominated semi-natural grassland is one component of a typical Satoyama landscape. M. sinensis most notably forms ring patches as a result of human management, which includes the removal of aboveground stems by burning. In this study, I hypothesized that M. sinensis aids the coexistence of several plant species under managed conditions because of its notable ring patches. To test this hypothesis I monitored the richness of plant species inside and outside M. sinensis ring patches for 5 years, which included one non-managed year, and compared richness between managed and non-managed years. Results showed that species richness was higher inside than outside patches in all cases, but that this effect was more prominent in managed years than in the non-managed year. Consequently, human management is promoting the coexistence of plant species in M. sinensis-dominated semi-natural grassland. Human management will likely play an important role in conserving plant species diversity in semi-natural grasslands by changing relationships among plants.

      Because of changes in riparian zones and water properties, human disturbances in terrestrial ecosystems can affect the decomposition of organic matter and invertebrate assemblages in forest streams. The aim of this study was to evaluate how changes in the riparian zones influenced leaf breakdown rates and colonization by invertebrate shredders. Leaves of Miconia chartacea were incubated in four streams of the same watershed that presented different conservation levels in the riparian zones. Leaf breakdown rates were higher in the presence of shredders and in the most preserved stream. In terms of abundance and biomass, shredders differed among streams, and the importance of these organisms on leaf decomposition decreased in altered streams. These results suggest the conservation level in the riparian zones influenced leaf decomposition mediated by shredders, and the observed decrease in breakdown rates was probably due to the high sensitivity of shredders to changes in the availability of food resources and habitat.

      Illegal hunting and fishing activities are of great relevance to conservation policies. Few studies with regional focus of the impacts of these activities in Brazil are available. The aim of this study was to characterize illegal hunting and fishing on a national level by collecting data from the environmental police. We analyzed reports prepared by 16 states, all of them which contained a variety of information about seized species, and showed a lack of standardization of data collection and presentation. Illegal fish seizures were predominantly of Amazonian species. Illegal hunting seizures showed the most uniform territorial distribution. Armadillos (Dasypodidae family), pacas (Cuniculus paca), and capybaras (Hydrochoerus hydrochaeris) were the most frequently seized species, and numerous seizures of Brazilian guinea pig (Cavia aperea) were reported in northeastern Brazil. The reports provided by environmental military police have great informative power for conservation policies, but they must be standardized among states to improve the quality of data provided and analysis.

      The unrestrained ongoing construction of dams in rivers of high-priority for conservation represents a common threat to environment and surrounding societies. In Brazil, despite several known negative impacts assigned to poorly planned construction of dams, Federal and State Governments maintain the policy of expansion of the hydroelectric matrix. The outcome includes impoundments of remaining rivers that are extremely important for biodiversity conservation. Here, we suggest strategies to prevent dams in remaining rivers proven to be of high priority for conservation or with potential to social disruption. Besides, we report a successful case study in areas of two important remaining tributaries of the Paraná River (the most dammed river in the Neotropics), Brazil, where the enactment of municipal laws protecting areas of the basins, initiatives to indicate features of the rivers as heritages and the creation of protected areas are among the effective measures to prevent new dams. Distinctive features in this effort have been the exchange of information among different stakeholders and the consequent empowerment of local actors. The strategies presented here are indicated to halt projects of new dams and are applicable and encouraged to be adopted throughout Brazil, provided that some aspects found in Paraná State may occur elsewhere.

      Ramos and Anjos (2014) worked with birds in two riparian “forests” from the northwest of the state of Paraná, southern Brazil, to evaluate how the width and biotic integrity of the “forests” affected the communities. One of their conclusions was that riparian forest should be expanded to a minimum of 50m of width on each side of a stream. I believe that Ramos and Anjos (2014) compared different environments with different sampling areas: one sampled area was covered by secondary vegetation, which has so far not reached the forest stage, and showed approximately 30% less arboreal vegetation than the second sampled area. This undermines some of the claims made by Ramos and Anjos (2014), for example that the riparian vegetation should be expanded to a minimum of 50m. The minimum width of the riparian forests must be better evaluated comparing samples of vegetation at similar regeneration stages.

      Unlike species with widespread distributions, few predictive models have been constructed for species with restricted or unknown distributions. One example of such a poorly studied species is Aristolochia gigantea, for which very conflicting information has been reported regarding its distribution. In this study, we present A. gigantea's distribution and range, the environmental factors responsible for its distribution and comments about the information available in the existing literature. The model of A. gigantea's distribution identified new areas that can be surveyed to potentially find new populations, and our results reinforce the importance of predictive models for studying the distributions of species, suggesting that ecological niche modeling can provide important contributions to the analysis of biogeographic patterns in little-studied plant species.

      We present a synthesis of the first 10 years of Long Term Ecological Research project in Amazonian Forest. We elucidate the natural dynamics of forest ecosystem processes and associated biota, and its changes caused by distinct pressures of selective timber extraction and forest fragmentation. We found that, for both plants and animals, densities of individuals and distribution of species assemblages are spatially heterogeneous in the mesoscale, even in relatively undisturbed forests, and that associations with topo-edaphic variables allow prediction of a considerable part of this variation. For biological groups whose dynamics were studied in the short-term, levels of change in species composition and densities were relatively high, and these changes were generally in tune with spatial environmental variation. The impact of selective logging on assemblages and ecosystem processes was normally moderate, and around 19 years were needed for recovering forest biomass and tree size distribution. Continued studies are needed to determine the time required for recuperation of timber stocks and pre-logging floristic composition. Selective logging appears to be compatible with the biodiversity conservation, but reduction and better planning of roads access may be more important than planned logging intensities. Habitat loss’ impact on organisms and ecosystem processes is large and long-lasting, once it induces the privation of many taxonomic groups’ species, higher tree mortality and accelerated forest dynamics. There was a negative synergy between the impacts of habitat loss and climatic changes, and a better understanding of these processes can only be obtained through long-term research.
