Abstract
Species distribution modeling (SDM) predicts the species distribution by the association among climatic variables and known occurrence records of a given species. This methodology either represents a promising alternative to generating species distribution in poorly sampled regions or for those taxonomic groups lacking specialists. Although Brazil is considered the richest country in relation to amphibians, most species remain poorly studied regarding their natural history, ecology, or even geographic distribution. To address this knowledge gap regarding the geographic distribution of amphibians in the Brazilian biomes Cerrado and Atlantic Forest, the general purpose of this project is to generate a continuously updated point occurrence database and determine the potential distribution for all possible species in these biomes. This database will make possible the development of the following three specific purposes: a) to determine the potential distribution of poorly studied, recently described, and/or threatened species, taking into account specific methodologies for species with few points of occurrence or implementing non-climatic variables in the modeling process; b) to determine the species' potential distribution under a climate change scenario, in order to identify areas with potential increased or decreased species richness in the future; and c) to use the species' potential distribution to determining priority areas for amphibian conservation in the mentioned biomes, considering different biological metrics (species richness, beta diversity, endemism, and presence of threatened species).
