Detecting Prey Preferences and Prey Switching
2021AbstractIn this chapter I consider the question of whether predators switch their preference for different types of prey as those prey change in abundance. There are numerous experiments in the literature focusing on this, but generally they have focused on a simplified analysis that ignores the functional response.

ON A PREY–PREDATOR–PATHOGEN MODEL WITH PREY PREFERENCE: A THEORETICAL STUDY
Journal of Biological Systems, 2011In the present paper, we study a prey–predator–pathogen model where the prey population suffer from an SI epidemic. The predator is assumed to exercise preferential predation. The prey preference mechanism ranges from predation only on the susceptible or only on the infective to proportional predation on both the prey types.

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.

Hellbender Prey Preference Is Superseded by Native and Nonnative Prey Behavior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.

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.

Rattlesnake Preference for Envenomated Prey: Species Specificity
Journal of Herpetology, 2008Abstract Ten Prairie Rattlesnakes (Crotalus viridis viridis) and 10 Western Diamondback Rattlesnakes (Crotalus atrox) were offered choices between envenomated (E) and nonenvenomated (NE) mice. Both species preferred E over NE mice when envenomation was accomplished by a conspecific but not when envenomation was accomplished by the other species ...

Forelimb indicators of prey‐size preference in the Felidae
Journal of Morphology, 2009AbstractThe forelimbs, along with the crania, are an essential part of the prey‐killing apparatus in cats. Linear morphometrics of the forelimbs were used to determine the morphological differences between felids that specialize on large prey, small prey, or mixed prey.

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 ...

Testing Predictions of the Prey of Lion Derived From Modeled Prey Preferences
The Journal of Wildlife Management, 2007Abstract: Apex predators are often threatened with extinction, and reintroduction is one method conservation managers are using to secure their persistence. Yet the ability to predict what these predators will eat upon reintroduction is lacking. Here we test predictions of the diet of the lion (
