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.

A note on periodic solutions in non-symmetric May-Leonard systems

, 2001
We shall give a proof in this extension of our previous paper for the conjecture about the occurrence of periodic orbits by means of Hopf bifurcation in non-symmetric May-Leonard systems.

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.

On the weakly competitive case in a two-species chemotaxis model

, 2016
In this article we investigate a parabolic-parabolic-elliptic two-species chemotaxis system with weak competition and show global asymptotic stability of the coexistence steady state under a smallness condition on the chemotactic strengths, which seems ...

Coinvasion-Coexistence Traveling Wave Solutions of an Integro-Difference Competition System [PDF]

, 2013
This paper is concerned with the traveling wave solutions of an integro-difference competition system, of which the purpose is to model the coinvasion-coexistence process of two competitors with age structure.

Some Discrete Competition Models and the Principle of Competitive Exclusion

, 2005
One of the fundamental tenets of ecology is the Competitive Exclusion Principle. According to this principle too much interspecific competition between two species results in the exclusion of one species.

Threshold dynamics scenario of a plants-pollinators cooperative system with impulsive effect on a periodically evolving domain

European Journal of Applied Mathematics
Flowering plants depend on some animals for pollination and contribute to nourish the animals in natural environments. We call these animals pollinators and build a plants-pollinators cooperative model with impulsive effect on a periodically evolving ...

Transition probabilities for general birth-death processes with applications in ecology, genetics, and evolution

, 2011
A birth-death process is a continuous-time Markov chain that counts the number of particles in a system over time. In the general process with $n$ current particles, a new particle is born with instantaneous rate $\lambda_n$ and a particle dies with ...
