Morphometric and abiotic characterization of Physalaemus cuvieri foam nests. A) Foam nest measurements: depth (D), area of ground covered by the nest (AS), nest volume (V); B) Measurements of relative air humidity 2 meters above the nests (RH2) and 2 cm around the nests (RH0); C) temperature measurements taken 2 m above the nests (T2), 2 cm around the nests (T0), on the foams surface (TS), within the central part of the foam (TC), and on the ground of the foam nest (TG).Horizontal bars indicate mean and the whiskers indicate SEM. Different letters indicate significantly differences between values.
