All females had oocytes at four different maturation stages and there were no significant correlations regarding size-fecundity variables. Leptodactylus typhonia leltodactylus Fitzinger,Neue Class.

If we do not consider population or climate differences, the observation of juveniles of 20 mm or larger in January in the present study suggests that clutches were laid in Octoberwhich corroborates the findings from gonad analysis that the reproductive activity begins in October. Rana fusca Schneider, leptodactykus, Hist.

This increase was recorded for L. From Wikipedia, the free encyclopedia. Leptodactylus Fitzinger, is divided into five large species groups, including the L.
Based on frog illustrated by Seba,Locuplet. The monthly rainfall varied along the year, with the most fuscsu months at the end of Fig. Such data demonstrate the environmental plasticity of the species and evidence that populations of the same species may present different patterns according to the climate under which they oeptodactylus.
The aim of this study was to characterize, for the central region of the State of Rio Grande do Sul, Brazil, the reproductive biology of Leptodactylus fuscus Schneider,based on the analysis of gonadal development of males and females, reproductive effort, size-fecundity relationships, and occurrence of sexual dimorphism in body size.
The following size-fecundity correlations were investigated for mature individuals: Leptodactylus typhonius — Boulenger,Cat. You can help Wikipedia by expanding it.

Mature oocytes of both ovaries were counted and the diameter of the ten largest ones was measured for each female.
