          Abstract

          Este estudo avaliou a composição da anurofauna, bem como a distribuição espacial e temporal das espécies em quatro poças permanentes em uma região montanhosa do Espírito Santo, sudeste do Brasil. Duas dessas poças são conectadas a fragmentos florestais por corredores florestais e as outras duas poças são circundadas por plantação de eucalipto e habitação humana. Foram registradas 22 espécies, incluídas em cinco famílias, entre dezembro de 2003 a novembro de 2004. Hylidae foi a mais rica e abundante, apresentando elevada sobreposição espacial. Nove espécies foram coletadas em vegetação abaixo de 0,60 m, sendo o sítio de vocalização mais utilizado. Riqueza de espécies e abundância foram maiores em meses chuvosos. Poças com corredores abrigaram maior riqueza de espécies. Adicionalmente quatorze espécies foram exclusivamente encontradas nessas poças. A estrutura da comunidade de anuros em poças permanentes nessa paisagem fragmentada é aparentemente determinada pela presença ou ausência de corredores florestais conectando fragmentos em topos de morro às poças d'água ocorrentes ao longo dos vales.

          Translated abstract

          This study evaluated the composition of anuran assemblages, and also the spatial and temporal distribution of those species in four permanent ponds. Two of these ponds are connected to Atlantic rainforest fragments by forest corridor and the other two are surrounded by Eucalyptus plantation and human settlement. Twenty-two species from five families were recorded from December 2003 to November 2004. Most species and individuals collected belong to Hylidae, which presented pronounced spatial overlap. Vegetation under 0.60 m was the most used calling site. Although not statistically supported, species richness and abundance were higher in rainy than dry months. Ponds with corridors had higher species richness and fourteen species were exclusively found on these ponds. The community structure of anurans in permanent ponds at this fragmented landscape is apparently dictated by the presence or absence of forest corridors connecting ponds to forest fragments.
