    Comparison of climate envelope models developed using expert-selected variables versus statistical selection

    Ecological Modelling 345 10-20.

    Climate envelope models are widely used to describe potential future distribution of species under different climate change scenarios. It is broadly recognized that there are both strengths and limitations to using climate envelope models and that outcomes are sensitive to initial assumptions, inputs, and modeling methods Selection of predictor variables, a central step in modeling, is one of the areas where different techniques can yield varying results. Selection of climate variables to use as predictors is often done using statistical approaches that develop correlations between...

    Anthropogenic impact on habitat connectivity: A multidimensional human footprint index evaluated in a highly biodiverse landscape of Mexico

    Ecological Indicators 72 895-909.

    Evaluating the cumulative effects of the human footprint on landscape connectivity is crucial for implementing policies for the appropriate management and conservation of landscapes. We present an adjusted multidimensional spatial human footprint index (SHFI) to analyze the effects of landscape transformation on the remnant habitat connectivity for 40 terrestrial mammal species representative of the Trans-Mexican Volcanic System in Michoacán (TMVSMich), in western central Mexico. We adjusted the SHFI by adding fragmentation and habitat loss to its original three components: land use intensity...

    The mammalian faunas endemic to the Cerrado and the Caatinga

    ZooKeys 644 105-157.

    We undertook a comprehensive, critical review of literature concerning the distribution, conservation status, and taxonomy of species of mammals endemic to the Cerrado and the Caatinga, the two largest biomes of the South American Dry-Diagonal. We present species accounts and lists of species, which we built with criteria that, in our opinion, yielded results with increased scientific rigor relative to previously published lists – e.g., excluding nominal taxa whose statuses as species have been claimed only on the basis of unpublished data, incomplete taxonomic work, or weak evidence. For...

    A United States national prioritization framework for tree species vulnerability to climate change

    New Forests 1-26.

    Climate change is one of several threats that will increase the likelihood that forest tree species could experience population-level extirpation or species-level extinction. Scientists and managers from throughout the United States Forest Service have cooperated to develop a framework for conservation priority-setting assessments of forest tree species. This framework uses trait data and predictions of expected climate change pressure to categorize and prioritize 339 native tree species for conservation, monitoring, management and restoration across all forested lands in the contiguous...

    The importance of herbivore density and management as determinants of the distribution of rare plant species

    Biological Conservation 205 77-84.

    Herbivores are often drivers of ecosystem states and dynamics and in many situations are managed either as livestock or through controlled or exploitative hunting of wild populations. Changes in herbivore density can affect the composition of plant communities. Management of herbivore densities could therefore be regulated to benefit plant species of conservation concern. In this study we use a unique spatial dataset of large herbivores in Norway to test whether herbivore density affects the distribution of rare red-listed plant species in tundra ecosystems, and to identify regions where...

    Modeling the Geographic Distribution of Prosopis africana (G. and Perr.) Taub. in Niger

    Environment and Natural Resources Research 6(2) 136.

    Prosopis africana is a species of great socio-economic importance, threatened with extinction from its natural habitat in Niger due to overexploitation. The main objective of this study is to determine the potential geographic distribution of P. africana in Niger. Climatic and botanical data has been collected and used to model the distribution, on the basis of principle of maximum entropy (MAXENT) using MAXENT 3.3.3k, DIVA-GIS 7.5, and ArcGIS 10.0. programs. Rainfall and temperature are the most significant variables in the distribution of P. africana in Niger. Thus the southern band of the...

    Should I stay or should I go? Climate change effects on the future of Neotropical savannah bats

    Global Ecology and Conservation 5 22-33.

    Most extant species are survivors of the last climate change event 20,000 years ago. While past events took place over thousands of years, current climate change is occurring much faster, over a few decades. We modelled the potential distribution area of bat species in the Brazilian Cerrado, a Neotropical savannah, and assessed the potential impacts of climate change up to 2050 in two scenarios. First we evaluated what the impact on the distributions of bat species would be if they were unable to move to areas where climate conditions might be similar to current ones. The novelty of our paper...

    Species Diversity, Distribution, and Conservation Status in a Mesoamerican Region: Amphibians of the Uxpanapa-Chimalapas Region, Mexico

    Tropical Conservation Science 9(4) 1940082916670003.

    The Uxpanapa-Chimalapas region, with one of the most extensive and best preserved tropical forest areas in Mexico, is undergoing major anthropogenic changes, and only some portions of the territory are under the protection of local communities. Although the biodiversity of the region is known to be high, no study has yet analyzed the diversity of amphibian species in the region or contributed to valuing the region in a context of amphibian conservation. Based on a review of databases and the existing scientific literature, as well as our own fieldwork, in this study, we analyze the amphibian...

    Global patterns in threats to vertebrates by biological invasions

    Proceedings of the Royal Society B: Biological Sciences 283(1823) 20152454.

    Biological invasions as drivers of biodiversity loss have recently been challenged. Fundamentally, we must know where species that are threatened by invasive alien species (IAS) live, and the degree to which they are threatened. We report the first study linking 1372 vertebrates threatened by more than 200 IAS from the completely revised Global Invasive Species Database. New maps of the vulnerability of threatened vertebrates to IAS permit assessments of whether IAS have a major influence on biodiversity, and if so, which taxonomic groups are threatened and where they are threatened. We found...
