Wasp and Ant Nests: Who Really Protects Whom? New Insights From Amazonian Forests

open access: yesAustral Ecology, Volume 51, Issue 5, May 2026.
ABSTRACT Studies of animal behaviour are often biased towards species that are large‐bodied or have broad geographic ranges, as these are easier to observe in nature. Consequently, our understanding of behavioural ecology is shaped by such biases, even though these studies have provided important insights.
