| The Pumpkin toadlet, Brachycephalus ephippium (Spix, 1824), is an orangish daily anuran, which inhabits the litter of the Atlantic Forest of Southeastem Brazil. During a survey of this species' natural history in the vicinities of Campinas (22º52'S, 46º49'W), São Paulo State, field observations were made on the oviposition behavior, in which after the male left the oviposition site, the female covered the surface of ali eggs with soil particles. She pressed and rolled each egg against the ground using her hindfeet, until the eggs were indistinguishable from the litter background. A clutch was obtained in laboratory and two others were found in the field. After 25 days of development the embryo possess a big yolk sac, differentiated mouth and a small tail... |

| It was sampled the litter frogs at altitudinal sites of a semideciduous mesophytic forest located at Sena do Japi (Jundiaí, São Paulo, 23º17'S, 47º00'W, 800-1300m altitude, 1500mm rain/year). Forty two plots of 8x8m were sampled in the dry/cold season of 1995: 21 at a Higher Site (HS) (1000m) and 21 at a Lower Site (LS) (850m). The plots were evenly located near, mid-distance, and far from the stream-bed. It was found a total of five species, three at each site. Eleutherodactylus guentheri comprised 83% of the individuals at HS and E. juipoca 67% at LS. The density of individuals was higher at HS and near the stream. The greater density at HS may be due to greater humidity there, provided by mist. The frogs may aggregate in wetter places (stream edges) in... |
