Levantamento de lagartos (Reptilia: Squamata) do município de Pedro II/PI, região nordeste do Brasil

Abstract

We present an inventory of lizard species from the municipality of Pedro II, a Cerrado/Caatinga ecotone region, located in the Serra da Ibiapaba Environmental Protection Area, in the State of Piauí, Northeast Brazil. Local wealth was sampled through active searches, occasional encounters and pitfall traps. We recorded a total of 20 species. One of the greatest riches among the areas sampled in the northern region of the state. The accumulation curve and wealth estimators indicated a possible increase in this number. As a result, the estimated wealth for the municipality may exceed the sampled wealth. Most of the species observed are common in both the Caatinga and Cerrado biomes. The composition of lizards in the municipality of Pedro II is more similar to that recorded in the municipality of Batalha, state of Piauí, which may be related to the geographic proximity between these areas. These results increase knowledge about the diversity of lizards in the state of Piauí and the northeast region, providing support for management and conservation actions in this region.
