We consider a periodic environment with favorable and unfavorable patches alternately arranged in one dimension. In such heterogeneous environments, invasive animals may undergo not only random diffusion but also directed movement toward favorable pa

It is shown that the problem of eliminating a less-fit allele by allowing a mixture of genotypes whose densities satisfy a system of reaction-diffusion equations with population control to evolve in a reactor with impenetrable walls is approximately

It is shown that a trick introduced by H. R. Thieme [6] to study a one-species integral equation model with a nonmonotone operator can be used to show that some multispecies reaction-diffusion systems which are cooperative for small population densit

Long-time asymptotic properties of the solutions of the system where f (u) is positive homogeneous of degree p>1, are studied. We also consider the corresponding linearly perturbed system It is shown that if A=α I, then the global existence of all s

One may expect that if one adds a vector field which points toward the origin to the right-hand side of a first-order system of ordinary differential equations for which the origin is globally stable, then the origin is globally stable for the new sy

We present an example of a predator-prey-like system with a prey-only state as a global attractor, and with the additional property that an attempt to control the prey by harvesting or poisoning both species produces solutions in which both populatio

One crucial measure of a species' invasiveness is the rate at which it spreads into a competitor's environment. A heuristic spread rate formula for a spatially explicit, two-species competition model relies on 'linear determinacy' which equates sprea
