Optimal Harvesting in Stream Networks: Maximizing Biomass and Yield
Tung D. Nguyen, Zhisheng Shuai, Tingting Tang +3
In this study, we develop a metapopulation model framework to identify optimal harvesting strategies for a population in a stream network. We consider two distinct optimization obj…
A New Perspective on Determining Disease Invasion and Population Persistence in Heterogeneous Environments
Poroshat Yazdanbakhsh, Mark Anderson, Zhisheng Shuai
We introduce a new quantity known as the network heterogeneity index, denoted by , which facilitates the investigation of disease propagation and population persistenc…
Impact of resource distributions on the competition of species in stream environment
Tung D. Nguyen, Yixiang Wu, Tingting Tang +4
Our earlier work in \cite{nguyen2022population} shows that concentrating the resources on the upstream end tends to maximize the total biomass in a metapopulation model for a strea…
Evolution of dispersal in advective patchy environments
Shanshan Chen, Junping Shi, Zhisheng Shuai +1
We study a two-species competition model in a patchy advective environment, where the species are subject to both directional drift and undirectional random dispersal between patch…
Maximizing Metapopulation Growth Rate and Biomass in Stream Networks
Tung D. Nguyen, Yixiang Wu, Amy Veprauskas +9
We consider the logistic metapopulation model over a stream network and use the metapopulation growth rate and the total biomass (of the positive equilibrium) as metrics for differ…
Global dynamics of a Lotka-Volterra competition patch model
Shanshan Chen, Junping Shi, Zhisheng Shuai +1
The global dynamics of the two-species Lotka-Volterra competition patch model with asymmetric dispersal is classified under the assumptions of weak competition and the weighted dig…
