Bifurcation Analysis of a Predator–Prey Model with Alternative Prey and Prey Refuges
International Journal of Bifurcation and ChaosIn 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 ...

Increased prey vulnerability as a result of prey-prey interactions
Hydrobiologia, 1995This study examines indirect effects in a trophic system with three levels, consisting of two prey species, a top predator, and an intermediate predator. Qualitative data showed that the activity of both the top predator Aeshna juncea (Odonata) and the active prey Heterocope saliens, (Copepoda) caused bouts of swimming in the sedentary prey Sida ...

Prey Behavior, Prey Dispersal, and Predator Impacts on Stream Prey
Ecology, 1994A recent model, designed with stream systems in mind, suggested that prey exchange (movement of prey among patches) tends to reduce predator impacts on prey density; that is, rapid prey immigration into a patch with predators can swamp local effects of predators on prey density.

L-shaped prey isocline in the Gause predator–prey experiments with a prey refuge
Journal of Theoretical Biology, 2015Predator and prey isoclines are estimated from data on yeast-protist population dynamics (Gause et al., 1936). Regression analysis shows that the prey isocline is best fitted by an L-shaped function that has a vertical and a horizontal part. The predator isocline is vertical.

Influence of prey reserve in a prey–predator fishery
Nonlinear Analysis: Theory, Methods & Applications, 2006This is a detailed expository contribution to sustainable marine resources, featuring the promotion of marine reserves as a fisheries management tool. The authors discuss the formal connections between a prey-predator system in a two-patch environment, in which the prey migrate randomly between patches, but the predator (fishing) is not permitted in ...

Predator–prey systems depend on a prey refuge
Journal of Theoretical Biology, 2014Models of near-exclusive predator-prey systems such as that of the Canadian lynx and snowshoe hare have included factors such as a second prey species, a Holling Type II predator response and climatic or seasonal effects to reproduce sub-sets of six signature patterns in the empirical data.

Stability and Bifurcation in a Predator–Prey System with Prey-Taxis
International Journal of Bifurcation and Chaos, 2020In this paper, we consider a generalized predator–prey system with prey-taxis under Neumann boundary condition, that is, the predators can survive even in the absence of the prey species. It is proved that for an arbitrary spatial dimension, the corresponding initial boundary value problem possesses a unique global bounded classical solution when the ...
