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 ...

AN ECO-EPIDEMIOLOGICAL STUDY WITH PARASITE ATTACK AND ALTERNATIVE PREY

Journal of Biological Systems, 2009
The present paper deals with the problem of a predator-prey system with disease in the prey population. We observe the dynamics of such a system under the influence of severe as well as unnoticeable parasite attack and also alternative food sources for predator population.

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 ...

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 ...

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 ...

Collembola as alternative prey sustaining spiders in arable ecosystems: prey detection within predators using molecular markers

Molecular Ecology, 2003
AbstractCollembola comprise a major source of alternative prey to linyphiid spiders in arable fields, helping to sustain and retain these predators as aphid control agents within the crop. Polymerase chain reaction primers were developed for the amplification, from spider gut samples, of DNA from three of the most abundant species of Collembola in ...

Alternative Food, Switching Predators, and the Persistence of Predator‐Prey Systems

The American Naturalist, 2001
Sigmoid functional responses may arise from a variety of mechanisms, one of which is switching to alternative food sources. It has long been known that sigmoid (Holling's Type III) functional responses may stabilize an otherwise unstable equilibrium of prey and predators in Lotka-Volterra models.

Culling Prey Promotes Predator Recovery—Alternative States in a Whole-Lake Experiment

Science, 2007
Many top-predator fish stocks in both freshwater and marine systems have collapsed as a result of overharvesting. Consequently, some of these communities have shifted into seemingly irreversible new states. We showed, for predators feeding on prey that exhibit food-dependent growth, that culling of fish prey may promote predator recovery.
