Dynamic of a stochastic predator–prey population

Applied Mathematics and Computation, 2011
Abstract A stochastic predator–prey model is studied. Firstly, we prove the existence, uniqueness and positivity of the solution. Then, we show the upper bounds for moments and growth rate of population. In some cases, the growth rate is negative and the population dies out rapidly. The paper ends with some reviews for the paper [13] .

Group formation stabilizes predator–prey dynamics

Nature, 2007
Theoretical ecology is largely founded on the principle of mass action, in which uncoordinated populations of predators and prey move in a random and well-mixed fashion across a featureless landscape. The conceptual core of this body of theory is the functional response, predicting the rate of prey consumption by individual predators as a function of ...

Unique coevolutionary dynamics in a predator–prey system

Journal of Theoretical Biology, 2011
In 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.

On models for the dynamics of predator-prey interaction

2007
A brief account of attempts at modelling the dynamics of predator-prey systems is presented. The original deterministic Lotka-Volterra model is not biologically realistic. Later workers have attempted to modify the basic features of that model to include biologically relevant parameters and to introduce the stochastic aspect into the computations ...
