Foraging behaviour in tadpoles of the

Figures Abstract Predators have documented post-encounter density-mediated effects on prey but their pre-encounter impacts, including behavioural alterations, can be substantial as well. Indices of feeding in anuran there is substantial debate as to the relevance of tadpoles as indicated by gut characteristics.

In tests with a 1 : 1 food ratio, the observed ratio of tadpoles Parasites are also common natural enemies that have substantial impacts on individual hosts, populations, and communities [ 91011 ].

Despite this possibility, there have been few studies of this nature to date [ 18192021 ].
