Control of mosaic disease using microbial biostimulants: insights from mathematical modelling [PDF]
A major challenge to successful crop production comes from viral diseases of plants that cause significant crop losses, threatening global food security and the livelihoods of countries that rely on those crops for their staple foods or source of income.

A food chain ecoepidemic model: infection at the bottom trophic level [PDF]
In this paper we consider a three level food web subject to a disease affecting the bottom prey. The resulting dynamics is much richer with respect to the purely demographic model, in that it contains more transcritical bifurcations, gluing together the ...

A model of competing species that exhibits zip bifurcation
The purpose of this paper is to present a concrete model of competing population species that exhibits a phenomenon called zip bifurcation. The Zip Bifurcation was introduced by Farkas in 1984 for a three dimensional ODE prey-predator system describing a

On a predator-prey system interaction under fluctuating water level with nonselective harvesting
A predator-prey model interaction under fluctuating water level with non-selective harvesting is proposed and studied in this paper. Sufficient conditions for the permanence of two populations and the extinction of predator population are provided.

Global periodic solutions in a plankton-fish interaction model with toxication delay
In this paper, a plankton-fish interaction model is proposed and analyzed with the help of delay differential equations. Firstly, the elementary dynamical properties of the system in the absence of time delay is discussed.

Homogenization techniques for population dynamics in strongly heterogeneous landscapes [PDF]
An important problem in spatial ecology is to understand how population-scale patterns emerge from individual-level birth, death, and movement processes.

Dynamic ecological system measures
The system decomposition theory has recently been developed for the dynamic analysis of nonlinear compartmental systems. The application of this theory to the ecosystem analysis has also been introduced in a separate article.

On the principle of competitive exclusion in metapopulation models [PDF]
In this paper we present and analyse a simple two populations model with migrations among two different environments. The populations interact by competing for resources. Equilibria are investigated.

Delayed stability switches in singularly perturbed predator-prey models [PDF]
In this paper we provide an elementary proof of the existence of canard solutions for a class of singularly perturbed predator-prey planar systems in which there occurs a transcritical bifurcation of quasi steady states.
