Austral Ecology, Volume 49, Issue 1, January 2024.We performed a systematic review on the available literature on in situ studies of neotropical tadpole diets focusing on diet composition and its sources of variation. Such studies approached in just a few instances the effects of seasonality, developmental stage and food selectivity on diet composition, but the available data indicate none of these ...
