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…
Impact of network connectivity on the dynamics of populations in stream environments
Tung D. Nguyen, Tingting Tang, Amy Veprauskas +2
We consider the impact of network connectivity on the dynamics of a population in a stream environment. The population is modeled using a graph theoretical framework, with habitats…
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…
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…
