Abstract

A four-day herpetofauna survey was undertaken monthly from October 2018 to September 2019 at the Estação Biologia Marinha Augusto Ruschi (EBMAR) nature reserve, a coastal forest remnant in south-eastern Brazil. Each survey involved active visual and auditory searching at night, pitfall traps and incidental observations. This study revealed 31 species of anurans and 28 reptiles. Swamp forest was the most used habitat by these species. Marginal vegetation was the most used microhabitat, followed by leaf litter and bromeliads. Regarding temporal occurrence, 27 (47%) species were occasional, 20 (34%) semi-constant and 11 (19%) constant. Three species are listed as Data Deficient (Chelonoidis carbonarius, Physalaemus signifer and Sphaenorhynchus pauloalvini) and two (3%) as Endangered (Ameivula nativo and Arcovomer passarellii). Thirty-seven (63%) species were recorded during the active survey whereas 11 (17%) were recorded in pitfall traps. The herpetofauna of EBMAR is spatially isolated because the surrounding landscape has been converted to agriculture and human settlement.

巴西东南部大西洋森林的沿海森林遗迹 Estação Biologia Marinha Augusto Ruschi 的爬行动物群

从 2018 年 10 月到 2019 年 9 月，在巴西东南部的沿海森林遗迹 Estação Biologia Marinha Augusto Ruschi（EBMAR）自然保护区每月进行一次为期四天的爬行动物调查。每次调查都包括夜间主动视觉和听觉搜索、陷阱捕捉和偶然观察。这项研究发现了 31 种无尾类动物和 28 种爬行类动物。沼泽森林是这些物种最常用的栖息地。边缘植被是最常用的微生境，其次是落叶层和凤梨。在时间出现方面，27 个物种（47%）偶尔出现，20 个物种（34%）半常出现，11 个物种（19%）常出现。三个物种被列为数据不足物种（Chelonoidis carbonarius、Physalaemus signifer 和 Sphaenorhynchus pauloalvini），两个物种（3%）被列为濒危物种（Ameivula nativo 和 Arcovomer passarellii）。在主动调查中记录到 37 个物种（63%），而在坑式陷阱中记录到 11 个物种（17%）。EBMAR 的爬行动物群在空间上是孤立的，因为周围的景观已被农业和人类居住区所取代。
