Abstract Infanticide is widespread across the animal kingdom, but the physiological drivers of infanticide versus care or neglect are relatively unexplored. Here, we identified salient environmental and physiological antecedents of infanticide in the mimic poison frog (Ranitomeya imitator), a biparental amphibian in which female parents feed their tadpoles unfertilized eggs.

Abstract Aim: Climate can have profound effects on reproductive behavior and physiology, especially in ectothermic animals. Breeding periods in amphibians have received little attention despite amphibian reliance on climate and water due to their reproductive biology and ecological diversity. The aim of this study is to determine how global climate impacts breeding periods in ectothermic animals through physiology, body size, and microhabitat. Location: All continents, except Antarctica.
