LIFE HISTORY SWITCH POINT PLASTICY IN RESPONSE TO POND DRYING ALYERS METAMORPH ALLOMETRY AND JUMPING PERFORMANCE
… to pond drying, we studied the túngara frog, Physalaemus pustulosus, a tropical anuran that breeds in highly ephemeral habitats. We conducted a field study with three different water depth treatments in 60 L mesocosms and measured time and size at metamorphosis, hind limb length and jumping …

Hormonal mechanisms for variation in female mate choice
… choice was examined in female túngara frogs (Physalaemus pustulosus), a Neotropical species in which mate choice has been well studied. Acoustic based phonotaxis tests were used to assay mate choice behaviors such as receptivity, permissiveness and discrimination. These behaviors are …
