Spatial Risk Effects From Lions Compound Impacts of Prey Depletion on African Wild Dogs [PDF]

open access: yesEcology and Evolution
Prey depletion threatens many carnivore species across the world and can especially threaten low‐density subordinate competitors, particularly if subordinates are limited to low densities by their dominant competitors.

Effects of human‐induced prey depletion on large carnivores in protected areas: Lessons from modeling tiger populations in stylized spatial scenarios [PDF]

open access: yesEcology and Evolution, 2019
Prey depletion is a major threat to the conservation of large carnivore species globally. However, at the policy‐relevant scale of protected areas, we know little about how the spatial distribution of prey depletion affects carnivore space use and ...

Long‐term data reveal fitness costs of anthropogenic prey depletion for a subordinate competitor, the African wild dog (Lycaon pictus) [PDF]

open access: yesEcology and Evolution
Within carnivore guilds, dominant competitors (e.g., lions, Panthera leo) are limited primarily by the density of prey, while subordinate competitors (e.g., African wild dogs, Lycaon pictus) have been limited by the density of dominant competitors ...

Prey depletion as a threat to the world's large carnivores [PDF]

open access: yesRoyal Society Open Science, 2016
Large terrestrial carnivores are an ecologically important, charismatic and highly endangered group of species. Here, we assess the importance of prey depletion as a driver of large carnivore endangerment globally using lists of prey species for each ...

Direct evidence of a prey depletion "halo" surrounding a pelagic predator colony. [PDF]

open access: yesProc Natl Acad Sci U S A, 2021
Significance Elucidating the mechanisms that regulate animal populations is a fundamental goal in ecology and is increasingly important at a time of unprecedented anthropogenic disturbance to ecosystems.

Prey depletion, interspecific competition, and the energetics of hunting in endangered African wild dogs, <i>Lycaon pictus</i>. [PDF]

open access: yesProc Natl Acad Sci U S A
Significance Declines of endangered species are often correlated with simultaneous changes in several environmental conditions. Biomonitoring technologies can help to identify which correlations are causal, by testing the mechanism hypothesized to link a

Mechanisms of density dependence in juvenile salmonids: prey depletion, interference competition, or energy expenditure?

open access: yesEcosphere, 2021
Density dependence is a strong regulator of animal populations, operating primarily through intraspecific competition for a limiting resource. Because food is generally limited in natural environments, it is typically assumed that increasing animal ...

Central place foragers, prey depletion halos, and how behavioral niche partitioning promotes consumer coexistence. [PDF]

open access: yesProc Natl Acad Sci U S A
Many seabirds congregate in large colonies for breeding, a time when they are central place foragers. An influential idea in seabird ecology posits that competition during breeding results in an area of reduced prey availability around colonies, a ...

Inter- and intra-annual differences in foraging ecology of the chick-rearing Brünnich’s guillemots (Uria lomvia) breeding in the High Arctic [PDF]

open access: yesRoyal Society Open Science
The foraging ecology of seabirds depends on both external and internal factors. Seabirds can modify their feeding strategy depending on current food availability to maintain optimal energy levels provisioned to the offspring. Here, we investigated inter-
