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 ...

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 [PDF]

Molecular Ecology, 2003
Collembola 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.

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.

Cyclic voles, prey switching in red fox, and roe deer dynamics – a test of the alternative prey hypothesis

Oikos, 2003
Medium‐sized predators sometimes switch to alternative prey species as their main prey declines. Our objective of this study was to test the alternative prey hypothesis for a medium sized predator (red fox, Vulpes vulpes ), a small cyclically fluctuating main prey (microtine voles) and larger

Internally driven alternation of functional traits in a multispecies predator–prey system

Ecology, 2010
The individual functional traits of different species play a key role for ecosystem function in aquatic and terrestrial systems. We modeled a multispecies predator–prey system with functionally different predator and prey species based on observations of the community dynamics of ciliates and their algal prey in Lake Constance.

Effects of alternative prey on cannibalism in age-1 bluefish

Journal of Fish Biology, 1999
Age‐1 bluefish Pomatomus saltatrix were offered both age‐0 bluefish and age‐1 Atlantic silversides Menidia menidia in the following proportions: 0:1·0, 0·25:0·75, 0·5:0·5, 0·75:0·25, 1·0:0. Atlantic silversides were consumed in greater proportion than offered throughout all treatments suggesting strong selection for silversides.

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 ...
