Alternative (un)stable states in a stochastic predator–prey model

Ecological Complexity, 2017
Abstract Stochastic models sometimes behave qualitatively differently from their deterministic analogues. We explore the implications of this in ecosystems that shift suddenly from one state to another. This phenomenon is usually studied through deterministic models with multiple stable equilibria under a single set of conditions, with stability ...

Alternative prey disrupt biocontrol by a guild of generalist predators

Biological Control, 2005
We examined the potential of a guild of generalist predators to control Colorado potato beetles (“CPB,” Leptinotarsa decemlineata) on potato. We were interested in determining whether beetle suppression would change with varying predator density, and with varying background densities of green peach aphids (“GPA,” Myzus persicae), which are common ...

Individual vulnerability to predation: the effect of alternative prey types

Freshwater Biology, 1988
SUMMARY. 1. Many examples of predator‐prey interactions from freshwaters suggest that apparent predator preferences result more from the relative vulnerabilities of prey than any positive choice by the predator.2. The rank order of vulnerability of seven invertebrate prey to nine invertebrate predators was measured in the laboratory.

Optimal foraging predators in Leslie Gower models with alternative prey

2011
Optimal foraging theory defines the diet choice of a predator by imposing that it chooses the prey that is instantaneously the most beneficial for him [1]. It has been shown that this phenomenon leads to a switching diet and to the persistence of both prey and predators in generalized Lokta-Volterra models [2, 3].
