Organisms are exposed to various predators in nature, aryl they need to respond to the presence of predators to maintain fitness. Antipredatory responses can be costly by reducing performance in Other important traits. This pr*t investigates the behavioural responses to chemical cues of predators and their potential on Other fitness-related trats in an aquatic grazer.
Study system and approach
A freshwater snail, Lymnaea stagnalis. Experimental research:
(a) exposure of snails to predator cues (fish and dragonfly larvae),
(b) behavioural assays to assess snail antipredatory resinnses, and
(c) quantification of the fitness effects of predator avoidance
