During the establishment phase of a biological invasion, population dynamics are strongly
influenced by Allee effects and stochastic dynamics, both of which may lead to extinction of …

Both biotic interactions and abiotic random forcing are crucial influences on population
dynamics. This frequently leads to roughly equal importance of deterministic and stochastic …

Allee effects are (broadly) defined as a decline in individual fitness at low population size or
density. They can result in critical population thresholds below which populations crash to …

A Poisson process is a commonly used starting point for modeling stochastic variation of
ecological count data around a theoretical expectation. However, data typically show more …

We critically review and classify models of single-species population dynamics subject to the
demographic Allee effect with emphasis on non-spatial, deterministic approach. Inclusion of …

In (st) age-structured populations, the long-run population growth rate is negatively affected
by temporal variation in vital rates. In most cases, natural selection should minimize …

Complex systems consist of many interacting elements which participate in some dynamical
process. The activity of various elements is often different and the fluctuation in the activity of …

Habitat fragmentation is one of the most ubiquitous and serious environmental threats
confronting the long-term survival of plant and animal species worldwide. As species …

Summary 1 Small and isolated populations of species are susceptible to loss of genetic
diversity, owing to random genetic drift and inbreeding. This loss of diversity may reduce the …

It is impossible to predict the exact behavior of all biological systems and how these same
systems are exemplified by patterns of complexity and regularity. Decades of research in …
