چکیده

Models exploring the relationships between species’ occurrences and sets of predictor variables produce two kinds of useful outputs. The first are estimates of the probability that species might occur at given unrecorded locations. The second are estimates of an area’s suitability for species. The use of empirical models of occurrence in conservation planning has Unidade de Macroecologia e Conservação, Universidade de Évora, Estrada dos Leões Évora, Portugal and Centre d’Ecologie Fonctionnelle et Evolutive, CNRS 1919 Route Mende 34293 Montpellier Cedex 5, France

Modeling Current and Future Potential Distributions of Caspian Pond Turtle (Mauremys caspica) under Climate Change Scenarios

Although turtles are the most threatened taxonomic group within the reptile class, we have a very limited understanding of how turtles respond to climate change. Here, we evaluated the effects of climate changes on the geographical distribution of Caspian pond turtle (Mauremys caspica). We used an ensemble approach by combining six species distribution models including artificial neural network...
