THE EFFECT OF PREY AND PREDATOR DENSITIES ON WOLF PREDATION
Ecology, 2002Predator kills rate (i.e., kills per predator per time) is routinely presupposed to depend exclusively on prey density. However, per capita rates of killing may typically depend on the density of both prey and predator. Unfortunately, our perception of many ecological phenomena may be limited by the inappropriate assumption that kill rates do not ...

PREDATORS COME AND PREDATORS GO: THE REVERSIBILITY OF PREDATOR-INDUCED TRAITS
Ecology, 2003While numerous studies have been conducted on the ecology and evolution of phenotypic plasticity, to really understand plasticity we need to expose organisms to different environments over several ontogenetic stages. In this way, we can examine whether organisms change their phenotypic strategy over ontogeny, whether there are developmental windows ...

Predator-prey relationships: Indiscriminate predation
Journal of Mathematical Biology, 1984The Gurtin and Levine model5 is studied in this paper under the assumption that the fecundity of prey depends on age as well as on the total population sizes of prey and predators. The purpose of this study is to see the effect of this density dependence on the stability criteria for the equilibria of the model equations.

Epidemics in predator-prey models: disease in the predators
Mathematical Medicine and Biology, 2002The author has recently proposed and investigated models for the study of interacting species subject to an additional factor, a disease spreading among one of them, that somehow affects the other one. The inadequacy of such a model comes from the basic assumption on the interacting species.
