Abstract: Phyllomedusa tarsius is an arboreal frog species that suspends its eggs on leaves above water in order to achieve the high relative humidity necessary for embryo development. I compared the hatching success of P. tarsius in ponds located in pasture, Vismia spp. regrowth, Cecropia spp. regrowth, forest fragments and continuous forest at a site in central Amazônia. Reproductive success of P. tarsius is measured as percentage of clutches producing at least one tadpole and number of tadpoles produced per clutch. Reproductive success was higher in Cecropia regrowth, forest fragments and continuous forest, compared to pasture and Vismia regrowth. Desiccation and flooding were the main causes of clutch loss in pasture and Vismia regrowth, while predation was more frequent in forest and Cecropia regrowth. The levels of successful of P. tarsius clutches observed across all habitat types suggests that a landscape mosaic including pasture, secondary growth and forest fragments may allow for recolonization and genetic exchange to occur in isolated forest patches. © 2003 Elsevier Ltd.
