Allee effect that refers to a positive relationship between individual fitness and population
density provides an important conceptual framework in conservation biology. While …

The theory of reaction–diffusion waves begins in the 1930s with the works in population
dynamics, combustion theory and chemical kinetics. At the present time, it is a well …

In the present, ecologists generally consider the interactions, which are directly related to the
density effects, that species have on each other, like predation, mutualism, refuge, etc …

Although the spatial dimension of ecosystem dynamics is now widely recognized, the
specific mechanisms behind species patterning in space are still poorly understood and the …

The geographic range of the blacklegged tick, Ixodes scapularis, is expanding northward
from the United States into southern Canada, and studies suggest that the lone star tick …

Complexity, Analysis and Control of Singular Biological Systems follows the control of real-
world biological systems at both ecological and phyisological levels concentrating on the …

We consider the Fisher-KPP equation in a wavelike shifting environment for which the wave
profile of the environment is given by a monotonically decreasing function changing signs …

Motivation is provided for the development of infectious disease models that incorporate the
movement of individuals over a range of spatial scales. A general model is formulated for a …

Parasites are an integral part of virtually all food webs and species communities. Here we
consider the invasion of a resident predator–prey system by an infectious disease with …

In this paper, the dynamical behaviors of an SEIR epidemic system governed by differential
and algebraic equations with seasonal forcing in transmission rate are studied. The cases of …
