Age-specific Foraging Strategies Among Pumas, And Its Implications For Aiding Ungulate Populations Through Carnivore Control

Humans have been controlling carnivore numbers for centuries. Predator hunting, however, may indirectly influence predator-prey dynamics unintentionally by influencing the age- and sex-structure of predator populations that exhibit intraspecific (IS) variation in prey selection. We tested for IS in a … read more

Weak Spatiotemporal Response of Prey to Predation Risk in a Freely Interacting System

The extent to which prey space use actively minimizes predation risk continues to ignite controversy. Methodological reasons that have hindered consensus include inconsistent measurements of predation risk, biased spatiotemporal scales at which responses are measured and lack of robust null … read more

Effects on White-Tailed Deer Following Eastern Coyote Colonization

The expansion or recovery of predators can affect local prey populations. Since the 1940s, coyotes (Canis latrans) have expanded into eastern North America where they are now the largest predator and prey on white-tailed deer (Odocoileus virginianus). However, their effect … read more

Predation Shapes the Evolutionary Traits of Cervid Weapons

Sexually selected weapons evolved to maximize the individual reproductive success of males in many polygynous breeding species. Many weapons are also retained outside of reproductive periods for secondary reasons, but the importance of these secondary functions is poorly understood. Here … read more

Do Wolves Ambush Beaver

Over the past decade, there has been much debating about whether wolves possess high-order cognitive abilities that facilitate deliberate or cooperative hunting strategies such as ambush to capture prey. Beavers can be important alternate or primary prey for wolves in … read more

The Forgotten Prey Of An Iconic Predator: A Review Of Interactions Between Grey Wolves Canis Lupus And Beavers Castor spp.

Predator–prey relationships can have wide-ranging ecological and landscapelevel effects. Knowledge of these relationships is therefore crucial to understanding how these systems function and how changes in predator–prey communities affect these systems. Grey wolves Canis lupus can be significant predators of … read more
