The effects of prey depletion on dietary niches of sympatric apex predators in Southeast Asia.

Integrative Zoology, 2020
Resource 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 ...

Prey depletion and foraging strategy in the Oystercatcher Haematopus ostralegus

Oecologia, 1977
The 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 ...

Diet responses of two apex carnivores (lions and leopards) to wild prey depletion and livestock availability

open access: yesBiological Conservation
Prey-depletion is a significant threat facing carnivores globally, resulting in reduced population numbers, diet alterations, and increased livestock consumption, which increases human-carnivore conflict. We compared the diets of lions (Panthera leo) and leopards (P.

PREY DEPLETION BY ODONATE LARVAE: COMBINING EVIDENCE FROM MULTIPLE FIELD EXPERIMENTS'

Ecology, 1987
In this paper we re—analyze previously published data regarding the response of several prey populations to manipulation of predaceous larval dragonfly (Insecta: Odonata) densities in four separate field enclosure experiments. Using a computer—intensive "rerandomization" approach to testing hypotheses, we show that the individual experiments were not ...

Effect of Localized Prey Depletion on Prey Selectivity by Fish

Transactions of the American Fisheries Society, 1988
Abstract I compared the prey consumption by bluegills Lepomis macrochirus feeding on two size-classes of Daphnia magna with the diets predicted by the apparent-size model of foraging. The diets of fish that were acclimated to the laboratory for only 1 or 2 weeks contained significantly more small prey than predicted, but the diets of fish acclimated to
