Resumo: | The herpetofauna of the Caatinga is still underestimated. A lack of knowledge of this group led the region to be perceived as having low species richness and endemism. This study aims to determine the species composition of the herpetofauna of the municipality of Nordestina. Data were collected using different techniques, such as pitfall traps and active searching. We used a bootstrap method to estimate the species richness of the local herpetofauna. We also calculated dominance and evenness indices. We recorded 3,969 specimens of 49 species. Snakes had the highest species richness, while lizards were more abundant. Anurans comprised 14 ± 0.8 species, with high evenness (J’ = 65.8%) and low dominance (D = 23.3%). The number of squamate species was the same as the amount observed (n = 36), and also had high evenness (J’ = 55.7%) and low dominance (D = 23.9%). In general, the studied area showed a pattern of evenness with low dominance, in addition to environmental stability, which is a characteristic of most conserved environments and leads us to stress the importance of this region to the maintenance of the biodiversity of the Caatinga biome. |

A falta de conhecimento levou essa região a ser considerada de baixa riqueza e endemismo. Este estudo tem como objetivo determinar a composição e riqueza de espécies da herpetofauna no município de Nordestina. Os dados foram coletados utilizando diferentes técnicas amostrais, como armadilha de interceptação e queda e procura ativa. A riqueza da herpetofauna foi estimada utilizando o estimador Bootstrap. Além disso, foram calculados também a dominância e equitabilidade por grupo taxonômico. No total, foram registrados 3.969 espécimes distribuídos em 49 espécies. As serpentes apresentaram maior riqueza, enquanto os lagartos foram mais abundantes. Para os anuros, estimou-se, aproximadamente, 14 ± 0,8 espécies, com alta uniformidade (índice de Pielou J’ = 65,8%) e baixa dominância (D = 23,3%), enquanto que, para os répteis, o valor de riqueza estimado foi o mesmo observado, também com alta uniformidade (J’ = 55,7%) e baixa dominância (D = 23,9%). No geral, a área apresenta um padrão de equitabilidade e baixa dominância, o que é uma característica dos ambientes mais conservados e nos leva a destacar a importância desta região para a manutenção da biodiversidade do bioma Caatinga.Universidade Federal de Santa Catarina2019-12-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n4p6310.5007/2175-7925.2019v32n4p63Biotemas; v. 32 n. 4 (2019); 63-782175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n4p63/42052Copyright (c) 2019 André Kaufer Leiteinfo:eu-repo/semantics/openAccessLeite, André KauferOliveira, Magno Lima Travassos deDias, Marcelo AlvesTinôco, Moacir Santos2019-12-12T07:56:23Zoai:periodicos.ufsc.br:article/65376Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2019-12-12T07:56:23Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
