Low apex carnivore density does not release a subordinate competitor when driven by prey depletion
Biological Conservation, 2021 Abstract 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 ...

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

Environment and Natural Resources Journal, 2022 Tigers (Panthera tigris) have disappeared from over 90% of their historical range, and extant populations face habitat loss, direct poaching, and prey depletion in otherwise suitable habitats.

A healthy but depleted herd: Predators decrease prey disease and density
Ecology, 2023 AbstractThe healthy herds hypothesis proposes that predators can reduce parasite prevalence and thereby increase the density of their prey. However, evidence for such predator‐driven reductions in the prevalence of prey remains mixed. Furthermore, even less evidence supports increases in prey density during epidemics.

African Swine Fever threatens Southeast Asia's 11 endemic wild pig species
Conservation Letters, 2021 The spread of the most recent African Swine Fever (ASF) outbreak in Asia since late 2018 poses a significant threat to endemic pig species and socioeconomic security. Within domestic pigs and free‐living Eurasian wild boars (both Sus scrofa) in Asia, ASF

Movement Ecology, 2022 Background Prey depletion is a threat to the world’s large carnivores, and is likely to affect subordinate competitors within the large carnivore guild disproportionately.

Frontiers in Microbiology, 2021 Many species of the ciliate genus Strombidium can acquire functional chloroplasts from a wide range of algal prey and are thus classified as generalist non-constitutive mixotrophs.

Journal of Avian Biology, 2008 Predation may reduce prey numbers in such extent that prey may be depleted, which has negative effects on predator populations. Prey depletion would be more likely when the number of predators increase and/or concentrate their activity in a certain area, as is the case of colonial birds.

Scientific Reports, 2022 Studies on resource utilisation by carnivores are essential as they aid in assessing their role in a community, by unravelling predator–prey relationships.
