Ecological aspects of Scinax argyreornatus (Anura, Hylidae) from a cacao plantation in Espírito Santo state, southeastern Brazil
We examined the gonads and stomach contents of 110 specimens of the hylid frog Scinax argyreornatus (snout-vent length range: 14.4-23.0 mm) from a cacao plantation in the municipality of Linhares, Espírito Santo state, southeastern Brazil. Females were significantly larger than males. The number of mature oocytes found in females varied from 94 to 197 (N = 15), and was positively related to female size. Isopods were the dominant prey in the diet of S. argyreornatus, which is somewhat unexpected considering this frog's scansorial habits and the fact that isopods are not usual items in the diets of most anurans.
