The Allometry of Prey Preferences

PLoS ONE, 2011
The distribution of weak and strong non-linear feeding interactions (i.e., functional responses) across the links of complex food webs is critically important for their stability. While empirical advances have unravelled constraints on single-prey functional responses, their validity in the context of complex food webs where most predators have ...

Prey morphology and predator sociality drive predator prey preferences [PDF]

Journal of Mammalogy, 2016
Predator prey preferences shape the dynamics of predator–prey assemblages. Understanding the determinants of a predator’s prey preferences is therefore important. Trends in prey preferences of the large African predators have been described at a species scale, limiting our ability to assess the influence of prey morphology (size and horns) and predator

Predicting carrying capacity of a large carnivore from prey densities: a new approach [PDF]

PeerJ, 2023
Background Large carnivores play a crucial role in maintaining the balance of the ecosystem. Successful conservation initiatives have often led to a huge increase in predators which has often led to negative interactions with humans.

Prey selection by the Barn Owl Tyto alba (Scopoli, 1769) in captivity

Journal of Threatened Taxa, 2009
We investigated prey selection of the Barn Owl Tyto alba under captive conditions where birds were allowed to choose among individuals of varying size from four field rodent species: Bandicota bengalensis, Millardia meltada, Tatera indica and Mus booduga.

Spatial variability in the abundance and prey selection of the corallivorous snail Drupella spp. in the southeastern Hainan Island, China

Frontiers in Marine Science, 2022
Global climate change has caused extensive loss of biodiversity and ecosystem function globally, particularly in coral reefs in shallow tropical waters.

Food preference of Amblyseius swirskii (Acari: Phytoseiidae) on different stages of Tetranychus urticae (Acari: Tetranychidae) and Bemisia tabaci (Hemiptera: Aleyrodidae) 

Persian Journal of Acarology, 2016
The prey preference of polyphagous predators plays an important role in suppressing different species of herbivorous mites and insects. Prey stages preference of the predatory mite, Amblyseius swirskii Athias-Henriot was investigated among egg ...

Preference for envenomated rodent prey by rattlesnakes [PDF]

Bulletin of the Psychonomic Society, 1978
Adult specimens of several rattlesnake species which struck and envenomated a mouse or which did not have an opportunity to strike were allowed to choose between an envenomated mouse and one manually killed by the experimenter. Only rattlesnakes that struck a mouse made a choice, and the envenomated mouse was selected most frequently.

Prey and nesting preferences of the alien wasp Isodontia mexicana (Hymenoptera, Sphecidae) in southern Germany [PDF]

Journal of Hymenoptera Research
Isodontia mexicana (Sphecidae) is a neozoic wasp in Europe. Since its first recording in France in the 1960s, it has spread throughout Europe and is now considered established. It preys on grasshoppers for its larvae but so far, there is little empirical

Prey preference pattern of Gaeolaelaps aculeifer (Acari: Laelapidae) on fungus gnats, Lycoriella auripila (Diptera: Sciaridae); a step toward efficient release

Persian Journal of Acarology, 2016
Lycoriella auripila Winnertz (Diptera: Sciaridae) is one of the most serious pests of mushroom cultures, Agaricus bisporus (Lange) Imbach. Damage of this pest can result in substantial yield losses directly and indirectly.
