Low apex carnivore density does not release a subordinate competitor when driven by prey depletion
Biological Conservation, 2021Abstract Conservation of competitively subordinate carnivores presents a difficult challenge because they are limited by dominant competitors. Prey depletion is one of the leading causes of large carnivore decline worldwide, but little is known about the net effect of prey depletion on subordinate carnivores when their dominant competitors are also ...

Abstract We suggest a theoretical framework for predicting the distribution of predators when interference between predators is insignificant but depletion of the prey population is important. The pattern of density-dependent mortality of the prey can then be predicted.

The nature and impact of fishing on predators that share a fished resource is an important consideration in ecosystem‐based fisheries management. Krill (Euphausia superba) is a keystone species in the Antarctic, serving as a fundamental forage source for predators and simultaneously being subject to fishing.

Prey depletion and foraging strategy in the Oystercatcher Haematopus ostralegus
Oecologia, 1977The responses of a population of Oystercatchers to their own depletion of their prey, the edible cockle Cerastoderma edule, have been examined in Strangford Lough, Northern Ireland., Cockle stocks were severely depleted each winter as a result of predation by Oystercatchers and about half the birds present in October in the main study area had left by ...

Prey size and prey density affect meal patterns of rats in depleting and nondepleting patches
Animal Behaviour, 1999We examined meal-ending decisions by rats feeding in depleting patches (where the rate of return decreased during a meal) and nondepleting patches (where the rate of return was constant) in a closed-economy, laboratory setting that allowed the precise measurement of feeding rates and meal patterns.

Timing of Shorebird Migration in Relation to Prey Depletion
The Auk, 1981Abstract The southward departure of migratory shorebirds (Charadrii) before the collapse of food supplies on the breeding grounds would seem to disprove the hypothesis that migratory timing is a trait actively maintained by selective pressures created by seasonal production of food supplies. In this study we looked at seasonal changes in

The effects of prey depletion on dietary niches of sympatric apex predators in Southeast Asia
Integrative Zoology, 2020AbstractResource depletion exerts opposing pressures on co‐occurring consumers to expand diets while limiting overlap with competitors. Using foraging theory as a framework, we tested the effects of prey availability on diet specialization and overlap among competing Asian predators: dhole, leopard, and tiger.

Prey depletion inside and outside the territories of redshank, Tringa totanus
Animal Behaviour, 1984Observations realisees pres de l'estuaire du Taw, Devon, ou T.t. se nourrit principalement sur l'amphipode Corophium volutator. Il ne semble pas que la diminution des ressources alimentaires en hiver soit moindre a l'interieur du territoire qu'a l'exterieur ce qui semblerait prouver que T.t.
