Seasonal and habitat structure of an anuran assemblage in a semideciduous forest area in Southeast Brazil

Abstract

In this study, we evaluated the reproductive activity and the temporal and spatial distributions of anuran assemblages in three environments within a semideciduous forest in Southeast Brazil, located at Municipality of Barão de Monte Alto, State of Minas Gerais, Brazil. The fi eld activities were carried out during three consecutive days, monthly throughout the rainy seasons of 2013-2014 and 2014-2015. We recorded 28 anurans species, distributed in eight families. We observed the spatial-temporal distribution of some species, and their associated reproductive behaviors through exploration of vocalizations at different sites. The spatial and temporal distribution of the species seems to adapt to abiotic and biotic factors of their environment.

Distribuição geográfica de Scinax crospedospilus (Anura, Hylidae), incluindo novos registros na Mata Atlântica de Minas Gerais (Brasil)

“…Em Minas Gerais, Lutz (1973) mencionou a ocorrência da espécie na parte mineira do Parque Nacional de Itatiaia, em Bocaina de Minas, e também em Rio Pomba ("agricultural station of Pomba"). Em seguida, S. crospedospilus foi registrado em Fervedouro (Moura et al, 2012;Silva et al, 2018), Viçosa (Lacerda et al, 2014;Pires & Feio, 2017;Silva et al, 2011), Itamonte (Conte et al, 2016), Juiz de Fora (Neves et al, 2017a;Pacheco et al, 2016;Silva et al, 2018), Barão do Monte Alto (Pereira et al, 2016;Pereira et al, 2020), Muriaé (Souza et al, 2016), Passa Quatro (Silva et al, 2016), Santa Rita de Jacutinga (Silva et al, 2016), Cataguazes (Assis & Feio, 2017;Silva et al, 2018), Chiador (Bang et al, 2017), Rio Preto (Neves et al, 2017b), Santa Bárbara do Monte Verde (Neves et al, 2017b), Araponga, Astolfo Dutra, Caratinga, Coronel Pacheco, Divino, Eugenópolis, Itanhandu, Muriaé, Piedade de Caratinga, Santa Bárbara do Leste, Santa Margarida, Santana do Deserto, Santos Dumont e São Francisco do Glória (Silva et al, 2018). Mais recentemente, S. crospedospilus foi reportado para algumas localidades em Mariana (Silveira et al, 2019) e na adjacência da Serra Azul em Brumadinho (Leite et al, 2019), na região do Quadrilátero Ferrífero.…”
