Enhanced conspicuousness of prey in warmer water mitigates the constraint of turbidity for predators.

ABSTRACT: Changes in environmental conditions impact predator-prey interactions by altering behavior through sensory and non-sensory (eg metabolic or cognitive) pathways. Elevated water temperature and turbidity are known to alter activity levels and anti-predator responses in prey fish, and are increasing globally as a result of anthropogenic activities. Less is known about how temperature and turbidity impact predators' ability to detect prey directly, or indirectly via changes to prey behavior. We quantified the detectability of Trinidadian guppies (Poecilia reticulata) free-swimming in a large arena from the perspective of a stationary visual predator (simulated as an underwater camera). We used a fully factorial experimental design testing the independent and combined effects of increase
