Conservation Science and PracticeLarge 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

Individual variation within parasite communities of endangered African lions [PDF]
Royal Society Open SciencePrey depletion and human–wildlife conflict threaten the critically endangered West African populations of lion (Panthera leo leo), which occupy less than 1.1% of their historic range in West Africa.

Crowding effects and depletion mechanisms for population regulation in prey-predator intraspecific competition model [PDF]
Computational Ecology and Software, 2019 The current investigation centres on the consequences of intra-specific rivalry involving predators in the predator-prey equation. A careful account of the investigation is offered mathematically of the model to offer insights into important outcomes ...

Density dependence, prey accessibility and prey depletion by fisheries drive Peruvian seabird population dynamics [PDF]
Ecography, 2018 In marine ecosystems top predator populations are shaped by environmental factors affecting their prey abundance. Coupling top predators’ population studies with independent records of prey abundance suggests that prey fluctuations affect fecundity parameters and abundance of their predators.

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

Incorporating nonlinearity with generalized functional responses to simulate multiple predator effects [PDF]
PeerJ, 2022 Predicting the combined effects of predators on shared prey has long been a focus of community ecology, yet quantitative predictions often fail. Failure to account for nonlinearity is one reason for this.

Ashmole's halo : direct evidence for prey depletion by a seabird
Marine Ecology Progress Series, 1987 Fish population densities were measured at various instances from 2 large colonies of double-crested cormorants Phalacrocorax auritus to test the hypothesis that seabirds deplete prey close to their colonies. Fish densities were significantly lower in bays used by cormorants for feeding than in those outside their foraging range.

Stochastic modelling of prey depletion processes. [PDF]
Journal 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.
