Co‐occurrence patterns in a steppe bird community: insights into the role of dominance and competition
Spatial co‐occurrence patterns are determined by environmental factors, such as food
availability or habitat characteristics and by biotic associations. When resources are limited …

Competitive exclusion in a general multi-species chemostat model with stochastic perturbations
C Xu, S Yuan, T Zhang - Bulletin of Mathematical Biology, 2021 - Springer
Based on the fact that the continuous culture of microorganisms in a chemostat is subject to
environmental noises, we present and analyze a stochastic competition chemostat model …

Competition in the chemostat: a stochastic multi-species model and its asymptotic behavior
C Xu, S Yuan - Mathematical biosciences, 2016 - Elsevier
In this paper, a stochastic chemostat model in which n-species compete for a single growth-
limiting substrate is considered. We first prove that the stochastic model has an unique …

Average break-even concentration in a simple chemostat model with telegraph noise
C Xu, S Yuan, T Zhang - Nonlinear Analysis: Hybrid Systems, 2018 - Elsevier
In this paper, we aim to investigate the effect of telegraph noise on the continuous culture of
microorganism in a chemostat. With the help of a finite-state Markov chain, we first construct …

Ergodic property of the chemostat: A stochastic model under regime switching and with general response function
The dynamics of chemostat involving stochastic perturbations is considered. Instead of
assuming the familiar Monod kinetics for nutrient uptake, a general class of functions is used …

Stochastic dynamics of the delayed chemostat with Lévy noises
D Zhao, S Yuan, H Liu - International Journal of Biomathematics, 2019 - World Scientific
This paper formulates and studies a delayed chemostat with Lévy noises. Existence of the
globally positive solution is proved first by establishing suitable Lyapunov functions, and a …

Stationary distribution of a chemostat model with distributed delay and stochastic perturbations
M Gao, D Jiang - Applied Mathematics Letters, 2022 - Elsevier
In this paper, we consider a Lotka–Volterra food chain chemostat model that incorporates
both distributed delay and stochastic perturbations. We obtain sufficient conditions for the …

Nonautonomous chemostats with variable delays
The appearance of delay terms in a chemostat model can be fully justified since the future
behavior of a dynamical system does not in general depend only on the present but also on …
