| Summary: | Data and analysis script for: Norin et al (in prep) Predator presence affects activity patterns but not food consumption or growth of juvenile corkwing wrasse (Symphodus melops) Please see readme file. Abstract: Indirect effects of predators can manifest themselves as changes in prey behaviour and physiology. Reduced prey activity is a common behavioural response to predation risk, generally resulting in reduced foraging and growth. Given that digestion requires energy, it has been suggested that prey will choose to eat smaller meals under predation risk to reserve a larger portion of the aerobic metabolic scope they have available for energetically demanding tasks more critical than digestion, such asescape. To test this prediction, we quantified food consumption and growth of juvenile corkwing wrasses (Symphodus melops) over 11 days in the presence or absence of a predator (Atlantic cod, Gadus morhua). We then quantified behaviour and food consumption of the same wrasses in behavioural arenas with a ... |
