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 ...

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.

Direct evidence of a prey depletion “halo” surrounding a pelagic predator colony [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 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. Here, we present direct evidence of a phenomenon known as “Ashmole’s halo”: a zone of prey depletion that is hypothesized to form ...

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 ...

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

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 ...

The impact on tigers of poaching versus prey depletion [PDF]

open access: yesJournal of Applied Ecology, 2008
Summary There exists a continuing dilemma in prioritizing conservation actions for large carnivores. Habitat loss, poaching, and prey depletion have often been cited as the three primary threats, but there is debate over the relative importance of each.

Stochastic modelling of prey depletion processes [PDF]

open access: yesJournal of Theoretical Biology, 2009
The modelling of prey-predator interactions is of major importance for the understanding of population dynamics. Classically, these interactions are modelled using ordinary differential equations, but this approach has the drawbacks of assuming continuous population variables and of being deterministic.

Fitness consequences of prey depletion for the common goby Pomatoschistus microps [PDF]

open access: yesMarine Ecology - Progress Series, 2002
Pomatoschistus microps (Pisces: Gobiidae), a predatory, benthic feeder, occurs in high densities in variable, shallow, muddy coastal waters where prey availability can be unpredictable. Here, we investigate the effect and consequences of prey depletion on the body condition and nest building of adult male fish using manipulative mesocosm experiments in

Changes in African lion demography and population growth with increased protection in a large, prey‐depleted ecosystem

open access: yesConservation Science and Practice
Large carnivores such as the lion are declining across Africa, in part because their large herbivore prey is declining. There is consensus that increased protection from prey depletion will be necessary to reverse the decline of lion populations, but few
