Predation and Predator Management *
2019Predation has shaped many facets of the ecology of plovers, including their life history traits, behaviors, and demography. Moreover, conservation often emphasizes managing predators to increase population size. I reviewed literature addressing impacts of predation on survivorship and reproductive success of plovers, as well as four management ...

The first task faced by the writer of any book is the setting of limits around the material to be covered. This is primarily an exercise in definition and, as with any such exercise, is an invitation to dispute. Nearly every textbook dealing with ecology offers a unique definition of predation.

The Journal of Industrial Economics, 1988
ONE common assumption in the post-McGee [1958] predatory pricing literature has been that the predatory firm must be larger (have 'deeper pockets'), than the victim of the predation, usually an entrant. This assumption stems from a model of predation in which the contesting firms sell at levels below cost until one of the firms exits after exhausting ...

Predating predators: An experimental study [PDF]
, 2001 Predating predators requires at least three specimen to which we refer as players 1, 2, and 3. Player 1 has simply to guess nature when trying to find food. Player 2 is hunting player 1 in the hope that 1 is well-fed but must also avoid being hunted by player 3.

Spatial Economic Analysis, 2012
Abstract In a spatial economic context, we analyse the incentive to prey of an incumbent facing the potential entrance by a rival. We show that the existence of space modifies the incentive to prey of the incumbent and the resulting equilibrium.

A PREY–PREDATOR MODEL WITH MICROPARASITE INFECTION IN THE PREDATOR
Journal of Biological Systems, 2008This paper aims to study the dynamical behaviors of a predator–prey system where the predator is affected by a microparasite infection. The effect of discrete time-delay is investigated. It has been shown that the time-delay can induce instability and oscillations via Hopf bifurcation.

Predation is one of the strongest evolutionary forces in the animal kingdom. The need to catch food influences the ecology, morphology, and behavior of predators and prey alike. As a consequence, predation risk has not only a stark effect on the single individual but further shapes food webs and whole ecosystems.

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 ...
