Dynamically unstable ESS in matrix games under time constraints

open access: yesbioRxiv, 2021
Matrix games under time constraints are natural extensions of matrix games. They consider the fact that, in addition to the payoff, a pairwise interaction has a further consequence for the contestants.

Adaptive dynamics in logistic branching populations [PDF]

open access: yes, 2007
We consider a trait-structured population subject to mutation, birth and competition of logistic type, where the number of coexisting types may fluctuate.

Global behavior for a diffusive predator-prey system with Holling type II functional response

open access: yesBoundary Value Problems, 2012
A strongly coupled self- and cross-diffusion predator-prey system with Holling type II functional response is considered. Using the energy estimate, Sobolev embedding theorem and bootstrap arguments, the global existence of non-negative classical ...

Large Time Behaviour of the Solution of a Nonlinear Diffusion Problem in Anthropology

open access: yesJournal of Mathematical Study, 2018
In this article we consider a reaction-diffusion model for the spreading of farmers in Europe, which was occupied by hunter-gatherers; this process is known as the Neolithic agricultural revolution.

Growth of Phytoplankton

open access: yesBiomedical Journal of Scientific & Technical Research, 2019
A central problem in biological dynamical systems is to determine the boundaries of evolution. Although this is a general problem, we prefer to give solutions for growth of the phytoplankton. AMS Mathematical Classiftcation: 92D40, 35B36, 35Q92, 37N25.

Metapopulation Dynamics with Migration and Local Competition [PDF]

open access: yes, 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.

DYNAMICS OF LESLIE-GOWER PREDATOR-PREY MODEL WITH ADDITIONAL FOOD FOR PREDATORS

open access: yes, 2017
We consider a Leslie-Gower predator prey model with additional food for predators. Here we investigate the dynamics of the model such as the permanence, determination of equilibrium points and their existence condition as well as their stability ...

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

open access: yes, 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 ...

The logistic modeling population: Having harvesting factor

open access: yes, 2015
: The present paper deals with the logistic equation having harvesting factor, which is studied in two cases, constant and non-constant. In fact, the nature of equilibrium points and solutions behavior has been analyzed for both of the above cases by ...

A Spatially Explicit Capture–Recapture Model for Partially Identified Individuals When Trap Detection Rate Is Less than One [PDF]

open access: yesCalcutta Statistical Association, Bulletin, 2017
Spatially explicit capture–recapture (SECR) models have gained enormous popularity to solve abundance estimation problems in ecology. In this study, we develop a novel Bayesian SECR model that disentangles two processes: one is the process of animal ...
