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 ...

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 ...

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.

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.

Emergent impacts of alternative resource in cannibalistic predator–prey system

Modeling Earth Systems and Environment, 2020
In this paper, a predator–prey model with cannibalistic effect in predator is presented. Naturally, juveniles predators are captured by their own adult predators in water population system. To reduce such conspecific capturing, alternative resource is supplied to adult predators as a supplementary food. The model is analyzed in terms of theoretical and

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
