ALTERNATIVE PREY AND THE DYNAMICS OF INTRAGUILD PREDATION: THEORETICAL PERSPECTIVES

Ecology, 2007
A rich body of theoretical literature now exists focused on the three-species module of intraguild predation (IGP), in which a top predator both attacks and competes with an intermediate predator. Simple models of intraguild predation are often unstable, either because one consumer is excluded, or because sustained oscillations emerge from long ...

An Investigation Into the Chemical Composition of Alternative Invertebrate Prey

Zoo Biology, 2011
The aim of this study was to determine the chemical composition of eight invertebrate species and evaluate their suitability as alternative prey. The species selected were rusty red cockroaches (Blatta lateralis), six‐spotted cockroaches (Eublaberus distanti), Madagascar hissing cockroaches (Gromphadorhina portentosa), fruit flies (Drosophila ...

A modified Leslie–Gower predator–prey model with alternative food and selective predation of noninfected prey

Mathematical Methods in the Applied Sciences, 2020
Infectious diseases affect prey populations, and predators choosing susceptible prey may lead to the extinction of the prey population. We propose a mathematical model of prey–predator interaction with the prey population divided into two classes: susceptible and infected.

Alternative extraguild prey modifies focal extraguild prey consumption and parasitism but not intraguild predation intensity

, 2021
Intraguild predation (IGP) refers to the predation of species that use similar resources and are, therefore, potential competitors. The consuming predator is known as the intraguild predator (IG-predator) and the predator or parasitoid being consumed as ...

Re-adaptation from alternative prey to target prey increased predation of predator on target mite

Systematic and Applied Acarology, 2019
Neoseiulus bicaudus (Wainstein) is a natural enemy of spider mite and thrip and also a potential biocontrol agent for Tetranychus turkestani (Tetranychidae). Tyrophagus putrescentiae (Schrank) is an important alternative prey of N.

Bifurcation Analysis of a Predator–Prey Model with Alternative Prey and Prey Refuges

International Journal of Bifurcation and Chaos
In this paper, we study the codimensions of Hopf bifurcation and Bogdanov–Takens bifurcation of a predator–prey model with alternative prey and prey refuges, which was proposed by Chen et al. [ 2023 ]. The results show that the predator–prey model can undergo a supercritical Hopf bifurcation or a Bogdanov–Takens bifurcation of codimension two under ...

Extirpation of alternative prey during a small rodent crash

Oecologia, 1992
We document two episodes, in different years, of Barn Owls (Tyto alba) preying on a winter population of Burrowing Owls (Athene cunicularia) on a southern California island. The predation in each case followed a marked shift in the diet of the Barn Owls, due to the cyclic decline of their normal small mammal prey.

4.2.2 Eriophyoid mites as alternative prey

1996
Publisher Summary This chapter discusses the influence of eriophyoid mites on the dynamics of tetranychid mites via a shared predator and vice versa. A striking feature of the relationship of predatory mites and free-living eriophyoid mites is that even the predators with a preference for eriophyoid mites also feed on other plant-inhabiting ...

Prey selection by linyphiid spiders: molecular tracking of the effects of alternative prey on rates of aphid consumption in the field

Molecular Ecology, 2004
AbstractA molecular approach, using aphid‐specific monoclonal antibodies, was used to test the hypothesis that alternative prey can affect predation on aphids by linyphiid spiders. These spiders locate their webs in cereal crops within microsites where prey density is high.

A Technique for Evisceration as an Alternative to Enucleation in Birds of Prey: 19 Cases

Journal of Avian Medicine and Surgery, 2013
Ocular trauma is common in birds of prey presented to wildlife clinics and rehabilitation centers. Enucleation is the procedure most commonly described for treatment of end-stage ocular disease or chronically painful eyes in birds; however, there are several disadvantages and risks to this procedure.
