Breeding biology of the rapids frog Limnomedusa macroglossa (Anura: Cycloramphidae) in Southern Brazil
Limnomedusa is a monotypic genus that occurs in association with rocky outcrops and stream beds. Based on observational and mark-recapture fieldwork from 2005 to 2008, we report the breeding biology of Limnomedusa macroglossa in southern Brazil. The reproductive season lasted from late August to ear...
