Control of mosaic disease using microbial biostimulants: insights from mathematical modelling [PDF]
, 2020 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.

Metapopulation Dynamics with Migration and Local Competition [PDF]
, 2002 MSC2000: primary 34D15, 34D23, 92B05; secondary 34K60, 34E13, 92D40.Many patch-based metapopulation models assume that the local population within each patch is at its equilibrium and independent of changes in patch occupancy.

Daphnias: from the individual based model to the large population equation [PDF]
, 2012 The class of deterministic 'Daphnia' models treated by Diekmann et al. (J Math Biol 61: 277-318, 2010) has a long history going back to Nisbet and Gurney (Theor Pop Biol 23: 114-135, 1983) and Diekmann et al. (Nieuw Archief voor Wiskunde 4: 82-109, 1984).

Adaptive dynamics in logistic branching populations [PDF]
, 2007 We consider a trait-structured population subject to mutation, birth and competition of logistic type, where the number of coexisting types may fluctuate.

A food chain ecoepidemic model: infection at the bottom trophic level [PDF]
, 2014 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 ...

Noise Induced Phenomena in the Dynamics of Two Competing Species [PDF]
, 2016 Noise through its interaction with the nonlinearity of the living systems can give rise to counter-intuitive phenomena. In this paper we shortly review noise induced effects in different ecosystems, in which two populations compete for the same resources.

The branching process with logistic growth [PDF]
, 2005 In order to model random density-dependence in population dynamics, we construct the random analogue of the well-known logistic process in the branching process' framework.

Asymptotic behavior of a metapopulation model [PDF]
, 2005 We study the behavior of an infinite system of ordinary differential equations modeling the dynamics of a metapopulation, a set of (discrete) populations subject to local catastrophes and connected via migration under a mean field rule; the local ...

A two-strain ecoepidemic competition model
, 2014 In this paper we consider a competition system in which two diseases spread by contact. We characterize the system behavior, establishing that only some configurations are possible.

Delayed stability switches in singularly perturbed predator-prey models [PDF]
, 2016 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.
