Anurans in a forest remnant in the transition zone between cerrado and atlantic rain forest domains in southeastern Brazil

This study presents the species richness, temporal distribution and reproductive activity of anurans from the Uaimií State Forest (Floresta Estadual do Uaimií – FLOE Uaimií), situated in the Quadrilátero Ferrífero region, municipality of Ouro Preto, Minas Gerais state, Brazil. Field activities were performed monthly from September 2009 to August 2010. We recorded 36 anurans species, distributed in 10 families. The greatest richness of the sampled sites corresponds to a permanent rivulet in a secondary forest. The majority of anuran species presented seasonal vocalization activity pattern, mainly in the rainy season. The anuran species composition of FLOE Uaimií is similar to others studied areas from the Quadrilátero Ferrífero region.

本研究针对位于巴西米纳斯吉拉斯州欧鲁普雷图市铁四角矿区（Quadrilátero Ferrífero）内的乌阿伊米州立森林（Floresta Estadual do Uaimií——FLOE Uaimií）的无尾两栖类（anurans），分析其物种丰富度、时间分布格局与繁殖活动特征。本研究于2009年9月至2010年8月期间每月开展野外调查工作，共记录到无尾两栖类36种，隶属于10个科。其中物种丰富度最高的样点为次生林内的永久性溪流；多数无尾两栖类物种呈现季节性鸣唱活动模式，且鸣唱活动主要集中于雨季。乌阿伊米州立森林（FLOE Uaimií）的无尾两栖类物种组成，与铁四角矿区（Quadrilátero Ferrífero）内其他已开展研究的区域相似。
