Interference competition between wolves and coyotes during variable prey abundance

Tyler R. Petroelje et al.

Summary: The study found significant overlap between wolves and coyotes in terms of activity, diet, and space use, indicating interference competition during different periods related to white-tailed deer fawns availability. Coyotes showed preference for smaller prey and greater population-level variation in resource use compared to wolves.

Spatial heterogeneity facilitates carnivore coexistence

Andrew B. Davies et al.

Summary: Contrary to previous studies suggesting strong spatial avoidance of lions by wild dogs, the primary lion-avoidance strategy of wild dogs was found to be selecting landscape features that aid in avoiding lion detection in this new study. This habitat selection by wild dogs was commonly used, especially in areas and during times of high lion-encounter risk, indicating a proactive response to lion risk. The findings suggest that spatial landscape heterogeneity could provide an alternative mechanism for carnivore coexistence, especially as shrinking carnivore ranges lead to increased contact between inferior competitors and dominant species.

Variable strategies to solve risk-reward tradeoffs in carnivore communities

Joel Ruprecht et al.

Summary: The Mesopredator release theory suggests that dominant predators suppress subordinate carnivores, but the study found that resource provisioning from competitively dominant cougars to coyotes through scavenging played a crucial role in shaping coyote behavior and space use. The interactions among carnivores were found to be multifaceted, with coyotes being both attracted to cougar kill sites but also frequently killed by cougars. The study also revealed that bobcats and black bears had different responses to cougar presence, with bobcats showing no influence and black bears avoiding them.
