Many populations occupy spatially fragmented landscapes. How dispersal affects the
asymptotic total population size is a key question for conservation management and the …

As there are no targeted medicines or vaccines for newly emerging infectious diseases,
isolation among communities (villages, cities, or countries) is one of the most effective …

For the two-patch logistic model, we study the effect of dispersal intensity and dispersal
asymmetry on the total population abundance and its distribution. Two complete …

Metapopulation theory assumes a balance between local decays/extinctions and local
growth/new colonisations. Here we investigate whether recent population declines across …

In this work, we study the model of a fish species growing logistically exploited by a fishing
fleet in a heterogeneous environment. The environment is made up of a network of fishing …

A metapopulation model is investigated to explore how the spatial heterogeneity affects
predator–prey interactions. A Rosenzweig–MacArthur (RM) predator–prey model with …

This paper is a follow-up to a previous work where we considered a multi-patch model, each
patch following a logistic law, the patches being coupled by symmetric migration terms. In …

We examine a multi-patch model of a population connected by nonlinear asymmetrical
migration, where the population grows logistically on each patch. Utilizing the theory of …

I discuss the acquisition and use of “background” data in mathematical epidemiology
models, advocating a proactive approach to the incorporation of said data. I illustrate various …

In this paper, we investigate a prey–predator community of fish coexisting in a multi-patches
model, where different fishing patches are interconnected through migration terms. Only the …
