Competition and response to predation risk: effects on morphological and behavioural defences in anuran larvae

What is it about?

If there are many of us, we are not afraid. When the number of individuals increases, the perception of predation risk decreases. Many theories propose that organisms, like tadpoles, respond to both actual and perceived predation risks. Few individuals sense elevated risk in the presence of predators, prompting adaptive measures such as morphological or behavioral changes. Such responses are absent at higher individual counts, signifying a reduced perception of predation risk when population density increases.
