Dynamic ecological system measures

Results in Applied Mathematics, 2019
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.

Implication of age-structure on the dynamics of Lotka Volterra equations

, 2019
2010 MSC : (35B35) 35B40 65M08 (65M25) 92D40 92D50 (92D25)International audienceIn this article, we study the behavior of a nonlinear age-structured predator-prey model that is a generalization of Lotka-Volterra equations.

Periodic oscillation in the delayed CF-system

, 2007
This paper deals with the stability analysis of an autonomous system of differential equations and a nonlinear system of reaction diffusion equations with discrete time delay which models the behavior of a predator population whose dynamics depends on ...

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.

Modeling of the switching effect on two prey and one predator with the presence of Allee effects and refuge

Computational and Mathematical Biophysics
To examine the dynamics of a predator’s interaction with two prey species, this study develops a comprehensive mathematical model that accounts for ecological complexities, including the Allee effect, prey switching behavior, and prey refuge.

Disaggregation behavior in the terrestrial isopod Porcellionides pruinosus as a new ecotoxicological endpoint for assessing infochemical disrupting activity

Ecological Indicators
Among rapid ecotoxicological bioassays for screening soil quality, avoidance behavior tests on gregarious edaphic species such as Porcellionides pruinosus are widely used.

Periodic dynamics of a general switching dynamical system

European Journal of Applied Mathematics
Seasonal changes and cyclical human activities (such as periodic fishing bans, Wolbachia-based mosquito population control, and school term breaks) have significant impacts on population dynamics.

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 ...

Evaluating the Fidelity of Data-Driven Predator-Prey Models: A Dynamical Systems Analysis

bioRxiv
In empirical predator-prey systems, understanding the inherent dynamics typically comes from analyzing a structural model fitted to observation data.
