Optimal foraging and predator–prey dynamics III
Theoretical Population Biology, 2003In the previous two articles (Theor. Popul. Biol. 49 (1996) 265-290; 55 (1999) 111-126), the population dynamics resulting from a two-prey-one-predator system with adaptive predators was studied. In these articles, predators followed the predictions of optimal foraging theory.

Historically, many of the models of the natural world, both marine and terrestrial, have involved only a single species, conceptually separating the species of interest from its environment. In fact, species are in continuous contact with other organisms and their physical environment.

Refuge-mediated predator–prey dynamics and biomass pyramids
Mathematical Biosciences, 2018Refuge can greatly influence predator-prey dynamics by movements between the interior and the exterior of a refuge. The presence of refuge for prey decreases predation risk and can have important impacts on the sustainability of a predator-prey system. The principal purpose of this paper is to formulate and analyze a refuge-mediated predator-prey model

Diet choice and predator—prey dynamics
Evolutionary Ecology, 1994We compare the dynamics of predator-prey systems with specialist predators or adaptive generalist predators that base diet choice on energy-maximizing criteria. Adaptive predator behaviour leads to functional responses that are influenced by the relative abundance of alternate prey. This results in the per capita predation risk being positively density-

Herbivore-Algae Predator–Prey Dynamics
2014A predator (herbivore) preys upon another species (algae). Can we express the dynamics of such an interaction? Can we find the period of the cycle of interaction? Upon what does this period most sensitively depend? This model has many analogies: the fox and hare, the lynx and rabbit, and even Garret Hardin’s classical Tragedy of the Commons.

Red queen dynamics in specific predator–prey systems
Journal of Mathematical Biology, 2014The dynamics of a predator-prey system are studied, with a comparison of discrete and continuous strategy spaces. For a [Formula: see text] system, the average strategies used in the discrete and continuous case are shown to be the same. It is further shown that the inclusion of constant prey switching in the discrete case can have a stabilising effect

Dynamics of Predator–Prey Metapopulations with Allee Effects
Bulletin of Mathematical Biology, 2016Allee effects increasingly are recognized as influential determinants of population dynamics, especially in disturbed landscapes. We developed a predator-prey metapopulation model to study the impact of an Allee effect on predator-prey. The model incorporates habitat destruction and predators with imperfect information about prey distribution. Criteria

Unique coevolutionary dynamics in a predator–prey system
Journal of Theoretical Biology, 2011In this paper, we study the predator-prey coevolutionary dynamics when a prey's defense and a predator's offense change in an adaptive manner, either by genetic evolution or phenotypic plasticity, or by behavioral choice. Results are: (1) The coevolutionary dynamics are more likely to be stable if the predator adapts faster than the prey.

Dynamics of competing predator–prey species
Physica A: Statistical Mechanics and its Applications, 1998Abstract We study the predator–prey model described by the Lotka–Volterra equations (N.S. Goel et al., Rev. Mod. Phys. 43 (1971) 231). These coupled non-linear differential equations are solved numerically and compared with Monte Carlo simulations. Spectral analysis of the data indicate the presence of a fixed set of frequencies and the absence of ...
