The Atlantic Forest is one of the largest and richest tropical rainforests on the planet, being one of the 25 world priorities for conservation. The Atlantic Forest portion located north of the São Francisco River corresponds to the Pernambuco Endemism Center (PEC). We describe the snake composition of the PEC, providing information about the diversity, natural history and geographical distribution of the species, based on records from five scientific collections and additional information from the literature. A total of 78 species of snakes distributed in eight families was registered in the Pernambuco Endemism Center. The Caatinga is the Brazilian biome that most shares species with the PEC, followed by Cerrado. On the other hand, seven species are considered endemic of this region. Most of the snake species in the PEC have been registered in forest (94.8%), followed by “Brejos Nordestinos” (46.1%), Tabuleiros (43.5%), Restingas (14.1%) and Mangroves (5.1%). The PEC snake fauna includes mainly terrestrial species (60.2%) and cryptozoic and/or fossorial species (21.7%), but also presents a high richness of semi-arboreal and arboreal species (29.5%). Vertebrates are the main food item consumed by the species (78% of species), among the main prey are mammals, lizards, and amphibians. Most species show a strictly nocturnal activity period (50%), followed by strictly diurnal (38%). The PEC is the most degraded and least known region of the Atlantic Forest, yet it has revealed a high richness of snake species, including seven endemic species. It is emphasized that regional conservation efforts need to be intensified, because few forests in the region are formally protected, and the majority consist of small and poorly protected fragments, which means that many species in the region may be in risk of extinction.

巴西伯南布哥地方病中心的蛇：多样性，自然历史和自然保护

大西洋森林是地球上最大，最丰富的热带雨林之一，是世界25大环境保护重点之一。位于圣弗朗西斯科河以北的大西洋森林部分对应于伯南布哥地方病中心（PEC）。我们根据五个科学馆藏的记录以及文献中的其他信息，描述了PEC的蛇的组成，提供了有关该物种的多样性，自然历史和地理分布的信息。伯南布哥地方病中心登记了分布在八个家庭中的总共78​​种蛇。Caatinga是巴西的生物群落，大多数与PEC共享物种，其次是Cerrado。另一方面，该地区有七种特有物种。PEC中的大多数蛇种都在森林中登记（94.8％），其次是“ Brejos Nordestinos”（46.1％），Tabuleiros（43.5％），Restingas（14.1％）和Mangroves（5.1％）。PEC蛇类动物主要包括陆生物种（60.2％）和隐生和/或s窝物种（21.7％），但也呈现出高度丰富的半树栖和树栖物种（29.5％）。脊椎动物是该物种消耗的主要食物（占物种的78％），其中主要的猎物是哺乳动物，蜥蜴和两栖动物。大多数物种表现出严格的夜间活动期（50％），其次是严格的昼间活动（38％）。PEC是大西洋森林中退化最严重，鲜为人知的地区，但它显示出蛇种的丰富性，其中包括7种特有种。需要强调的是，需要加强区域保护工作，
