ABSTRACT
Thirty of the 65 Neotropical species of Campylopus Brid. (Bryophyta, Leucobryaceae) occur widely distributed in Brazil. Therefore, identifying the environmental factors that affect the distribution of these species is essential to predict the future pattern of distribution and assess their conservation status of the genus. Using the DIVA-GIS software, distribution maps for species were elaborated from 118 occurrence points. The data were applied in a predictive modeling analysis of areas with the best climatic conditions for the establishment of the endemic Brazilian species of Campylopus (C. dichrostis, C. fragilis, C. gatro-alaris, C. gemmatus, C. julicaulis, C. subcuspidatus, C. thwaitesii, C. uleanus and C. widgrenii). The climatic variables were obtained from Worldclim (resolution 2.5 min.). As a result, the current predictive modeling indicated the preference for the Cerrado and the Atlantic Rainforest. Considering a future scenario of global warming, the modeling suggests a decrease in the areas favorable for the occurrence of species of Campylopus.
