Seasonal patterns of breeding activity of Atlantic Rainforest anurans at Boracéia, Southeastern Brazil

Abstract

Annual patterns of breeding activity of 28 anuran species were studied at Boracéia, an Atlantic Rainforest locality in the coastal mountains of Southeastern Brazil. Five patterns were evident: (1) species that call year-round; (2) opportunistic calling activity associated with rainfall; (3) explosive breeding; (4) winter activity; and (5) summer species with variable breeding seasons. The number of species with calling males was positively correlated with mean monthly temperature.
