Population size in stochastic multi-patch ecological models
Alexandru Hening, Siddharth Sabharwal
We look at the interaction of dispersal and environmental stochasticity in -patch models. We are able to prove persistence and extinction results even in the setting when the di…
Dynamics of stochastic microorganism flocculation models
Alexandru Hening, Nguyen T. Hieu, Dang H. Nguyen +1
In this paper we study the dynamics of stochastic microorganism flocculation models. Given the strong influence of environmental and seasonal fluctuations that are present in these…
Population dynamics under random switching
Alexandru Hening, Siddharth Sabharwal
Populations interact non-linearly and are influenced by environmental fluctuations. In order to have realistic mathematical models, one needs to take into account that the environm…
Population size in stochastic discrete-time ecological dynamics
Alexandru Hening, Siddharth Sabharwal
We study how environmental stochasticity influences the long-term population size in certain one- and two-species models. The difficulty is that even when one can prove that there…
