Anfíbios da Esta？？o Ecológica Serra Geral do Tocantins, regi？o do Jalap？o, Estados do Tocantins e Bahia

the northern part of cerrado is one of the biologically poorest known areas in the domain. recent studies revealed richness values that are as high as those from other sites in the domain. the esta？？o ecológica serra geral do tocantins is located in a region known as jalap？o, in northeastern cerrado, and it is included in the largest set of protected areas in the domain. we describe amphibian richness and species composition in eesgt, and discuss it in a biogeographic context. we also describe breeding sites focusing on phytophysiognomy and types of water bodies. we sampled amphibians through active search and pitfall traps, during the peak of breeding season for most of the anuran species in cerrado. we registered 36 species, which coupled with former studies results in a regional richness of 39 species known for jalap？o. after applying jackknife estimator, we suggest a potential richness of 42 species for the eesgt. most registered species are endemic or strongly associated to cerrado, followed by species widespread in brazil or south america, and those associated with caatinga. most species breed in temporary ponds located in open areas, although there are some forest specialists, and stream-breeding species.
