Direct competition for resources is especially fierce among predators, leading to disproportionately strong effects on fitness and functional roles. These competitive are exacerbated in complex predator guilds with dominance hierarchies that have clear winners losers. The direct costs of losing these competitions well understood, but the drivers such interactions, their indirect prey, not. We evaluate interference cougars, how affects cougar-prey dynamics, by leveraging 23 years cougar...
Mesocarnivores must balance the negative (competition) and positive (carrion provisioning) effects of dominant apex carnivores to coexist in shared landscapes. How mesocarnivores navigate such top-down have typically been examined through a risk-reward lens. However, risks accrued by might not be even across all apex-mesocarnivore pairings multi-carnivore systems, instead can mediated species-specific interactions. Using remote-camera surveys from 2021-2023, we estimated (wolf, cougar)...
Gray Wolves (Canis lupus) are territorial, group living carnivores that live in packs typically consisting of a dominant breeding pair and their offspring. Breeding tenures relatively short competitive, with vacancies usually occurring following breeder’s death, often filled by unrelated immigrants or relatives the previous breeder. The frequency conditions active breeder displacements poorly understood. Position changes dominance hierarchy common yet rarely documented detail. We describe...
