Abstract:Infanticide is widespread across the animal kingdom. However, the physiological mechanisms underlying infanticide versus care or neglect are relatively unexplored. Here, we identified salient environmental and physiological antecedents of care and infanticide in the mimic poison frog (Ranitomeya imitator), a biparental and monogamous amphibian in which female parents feed their tadpoles with unfertilized eggs. Specifically, we explored potential environmental cues by evaluating changes in the frequency of food… Show more
