“…To investigate the relationship of the Brejos with the Caatinga and the northeastern coastal Atlantic Forest, we examined nine snake assemblages located in Caatinga: RPPN Fazenda Almas, São João do Cariri, Imaculada, Pedra da Bola, Olho D'Água Branco (PereiraFilho et al 2017), Exu (Vitt and Vangilder 1983), Catimbau (Pedrosa et al 2014), Juazeiro (Freitas et al 2016), and Serra de Santa Catarina (Abrantes et al 2018), as well as seven located in the northeastern coastal Atlantic Forest: Sema II, Mata do Buraquinho, RPPN Gargau, Mata da Usina São João, Sema III (PereiraFilho et al 2017), Parque Dois Irmãos (Melo et al 2018), and Serra do Urubu (Roberto et al 2017). In both analyses, we utilized a matrix of presence and absence for 266 species.…”
