Coping with change in predation risk across space and time through complementary behavioral responses.

Area of Science:

• Behavioral ecology
• Predator-prey dynamics
• Wildlife management

Background:

• Understanding prey behavioral responses to predation risk is fragmented.
• Few studies jointly analyze complementary behaviors like habitat use and vigilance.
• A simplified system with European rabbits and feral cats was used to study risk perception.

Purpose of the Study:

• To investigate how changes in predation risk influence prey decisions on habitat use, timing, and activity.
• To assess the interplay between habitat selection and fine-scale behaviors in response to risk.
• To map the 'landscape of fear' for prey species.

Main Methods:

• Monitoring rabbit presence and behavior in open and closed foraging patches.
• Recording cat activity patterns, noting individual recognition.
• Correlating environmental conditions (e.g., wind) with prey and predator behavior.

Main Results:

• Feral cats were more active in closed patches at night, indicating higher hunting success.
• Rabbits avoided closed patches at night and increased vigilance when present.
• Rabbits utilized closed patches more in windy conditions, likely for thermoregulation.

Conclusions:

• Prey habitat use and vigilance are complementary strategies for managing predation risk.
• Analyzing only one behavior can lead to inaccurate conclusions about risk management.
• Future research should explore individual variations in behavioral responses to perceived risk.
