- We analyzed the reproductive pattern in males of Physalaemus riograndensis (n = 276). To identify the potential breeder males (n = 100), the presence of secondary sexual characters were recorded. These males were found mainly from September to April, and two peaks of abundance were observed. Breeding activity was positively correlated with temperature, but did not correlate with rainfall. As occurs with females of P. riograndensis , the fat bodies increased synchronously with the gametogenic activity, coinciding with the period of highest reproductive activity for the species (October to April). Therefore, these structures could be used as reserves of energy for reproduction in males.
