Abstract In specialized predators, a variety of adaptations have evolved to such a level of specificity that they allow very effective exploitation of focal prey. Venom is an essential adaptive trait of predatory venomous species, such as spiders, yet our knowledge of spider venom is incomplete.

Hellbender Prey Preference Is Superseded by Native and Nonnative Prey Behavior
Journal of Herpetology, 2018Abstract Long-term interactions often shape predator–prey relationships in the form of a co-evolutionary “arms race.” The arrival of nonnative species may disrupt these relationships by introducing novel behaviors that shift interactions in favor of one of the participants.

Prey size preference in the tokay gecko
2023In this experiment we presented male and female, adult tokay geckos with a choice between two crickets from they size categories: small, medium and large. Geckos were allowed to choose one prey and their choice, as well as their attack latency were recorded.

The Science of Nature, 2015
Prey-specialised spiders often do not have brood care and may not deposit eggs in the proximity of the preferred prey. Thus, naïve spiderlings are left to their own to find their focal prey. Our aim was to reveal whether the choice of a specific prey is innate and whether familiarisation with a certain prey will condition prey choice.

Earwig preying on ambrosia beetle: Evaluating predatory process and prey preference
Journal of Applied Entomology, 2020AbstractEarwigs (Dermaptera), such as Forficula auricularia L., are important euryphagous predators for a wide variety of prey and can markedly influence the populations of orchard pests. Most previous studies on earwig feeding behaviour have not used adult beetles of the prey species; few researchers have focused on prey preference in earwigs.

Planktivore Preference by Prey Size
Ecology, 1982The reactive field volume model of prey encounter was shown to give a close approximation to the apparent size model of prey encounter rate for prey size distributions consisting of many prey types. The two models of prey encounter give almost identical predictions for the Lake Washington zooplankton community.

Prey preference and prey switching in Anthocoris minki Dohrn (Hemiptera: Anthocoridae)
Journal of Asia-Pacific Entomology, 2018Abstract The understanding of host specificity of predacious insects is one of the most important problems in the investigation of biological control. Prey preference and the potential for prey switching in Anthocoris minki Dohrn (Hem.: Anthocoridae) was assessed in two- choice experiments under environmentally controlled conditions.

Prey preference by Metaseiulus occidentalis (Acari: Phytoseiidae) and the role of prey aggregation
Biological Control, 1991Abstract The phytoseiid predator Metaseiulus occidentalis is an important biological control agent for the Pacific spider mite (PSM) Tetranychus pacificus and the Willamette spider mite (WSM) Eotetranychus willamettei, two economically important spider mite species in California vineyards. Field observations indicated that M.

Predators and microorganisms of prey: goshawks prefer prey with small uropygial glands
Functional Ecology, 2010Summary 1. The uropygial gland of birds produces chemical substances with antimicrobial properties that have been shown to reduce the abundance of feather degrading bacteria and other microorganisms. These microorganisms would affect the flight capabilities of birds and, consequently, a relationship between size of uropygial glands and probability of ...

Hunger, partial consumption of prey and prey size preference in a carabid beetle
Ecological Entomology, 1988ABSTRACT. Partial consumption of prey and prey size preference were studied in females of the carabid Notiophilus biguttatus F., using different size‐classes of the springtail
