Invasion of alien species is one of the major threats for natural community structures,
potentially leading to high economic and environmental costs. In this work, we study through …

Classical models for biological invasions were single-species models in homogeneous
landscapes, but most invasions happen in the presence of interacting species and in …

Habitat heterogeneity can have profound effects on the spreading dynamics of invasive
species. Using integro-difference equations, we investigate the spreading dynamics in a one …

A few spatiotemporal models of population dynamics are considered in relation to biological
invasion and biological control. The patterns of spread in one and two spatial dimensions …

Spread of populations in space often takes place via formation, interaction and propagation
of separated patches of high species density, without formation of continuous fronts. This …

The dynamics of interacting ecological populations results from the interplay between
various deterministic and stochastic factors and this is particularly the case for the …

We determine the density profile and velocity of invasion fronts in one-dimensional infinite
habitats in the presence of environmental fluctuations. The population dynamics is …

Patterns and rates of invasive species spread have been a focus of attention for several
decades. Majority of studies focused on the species proliferation in a relatively uniform …

Spatial proliferation of invasive species often causes serious damage to agriculture, ecology
and environment. Evaluation of the extent of the area potentially invadable by an alien …

Classical models of biological invasions generally assume that introductions consist of
single releases of organisms, whereas in nature successful invasions are usually the result …
