Levantamento da anurofauna do Parque Nacional de Sete Cidades - PI, nordeste do Brasil

Abstract

The Sete Cidades National Park is located in the municipalities of Piracuruca and Brasileira, State of Piauí, in a transition zone between the Caatinga and Cerrado biomes. Studies on its herpetofauna are limited to amphibian distribution notes and an inventory of snakes. Therefore, here is an unprecedented list of anuran species from the Sete Cidades National Park, Piauí State, Northeastern Brazil. The specimens were collected in the rainy season of 2019 and one of the greatest species richness among all conservation units of the state was recorded, in addition to increasing the geographical distribution of a species to the state. Most of the observed species are common in both caatinga and cerrado biomes or have wide distribution in Brazil. The composition of anurans of the Sete Cidades National Park is more similar to that recorded in the Environmental Protection Area of the Parnaíba Delta, states of Ceará, Piauí and Maranhão and Conservation Units in the states of Piauí, Ceará and Maranhão. These results increase knowledge about the diversity of anurans in Northeastern Brazil, providing subsidies for management and conservation actions of an important National Park in Brazil.
