The effect of dispersal on asymptotic total population size in discrete-and continuous-time two-patch models

C Grumbach, FN Reurik, J Segura, D Franco… - Journal of Mathematical …, 2023‏ - Springer
Many populations occupy spatially fragmented landscapes. How dispersal affects the
asymptotic total population size is a key question for conservation management and the …

Dispersal asymmetry in a two-patch system with source–sink populations

H Wu, Y Wang, Y Li, DL DeAngelis - Theoretical Population Biology, 2020‏ - Elsevier
This paper analyzes source–sink systems with asymmetric dispersal between two patches.
Complete analysis on the models demonstrates a mechanism by which the dispersal …

Effects of diffusion on total biomass in simple metacommunities

A Ruiz-Herrera, PJ Torres - Journal of Theoretical Biology, 2018‏ - Elsevier
This paper analyzes the effects of diffusion on the overall population size of the different
species of a metacommunity. Depending on precise thresholds, we determine whether …

Population abundance in predator–prey systems with predator's dispersal between two patches

R Huang, Y Wang, H Wu - Theoretical Population Biology, 2020‏ - Elsevier
This paper considers predator–prey systems in which the predator moves between two
patches. One patch is a source, where the predator and prey can persist, while the other is a …

Population abundance of two-patch competitive systems with asymmetric dispersal

Y Wang, H Wu, Y He, Z Wang, K Hu - Journal of Mathematical Biology, 2020‏ - Springer
This paper considers two-species competitive systems with two patches, in which one of the
species can move between the patches. One patch is a source where each species can …

[HTML][HTML] The role of the spatial topology in trophic metacommunities: Species with reduced mobility and total population size

A Ruiz-Herrera - Journal of Theoretical Biology, 2023‏ - Elsevier
A central question in ecology is understanding the influence of the spatial topology on the
dynamics of a metacommunity. This is not an easy task, as most fragmented ecosystems …

Optimal dispersal and diffusion-enhanced robustness in two-patch metapopulations: origin's saddle-source nature matters

M Jorba-Cuscó, RI Oliva-Zúniga, J Sardanyés… - Theory in …, 2024‏ - Springer
A two-patch logistic metapopulation model is investigated both analytically and numerically
focusing on the impact of dispersal on population dynamics. First, the dependence of the …

Bifurcations in diffusive predator–prey systems with Beddington–DeAngelis functional response

Z Wang, Y Wang - Nonlinear Dynamics, 2021‏ - Springer
Understanding how species' diffusion and environmental heterogeneity affect natural
population dynamics is crucial in wildlife management and biodiversity conservation. In this …

Pollination-mutualisms in a two-patch system with dispersal

Y Wang - Journal of Theoretical Biology, 2019‏ - Elsevier
In this paper, we consider a two-patch pollination-mutualism model with dispersal, which is
derived from resource-service exchange between the plant and pollinator. The pollinator is …

Optimal network architectures for spatially structured populations with heterogeneous diffusion

A Ruiz-Herrera, PJ Torres - The American Naturalist, 2020‏ - journals.uchicago.edu
The motivation of this article is to derive new management guidelines to maximize the
overall population size using popular management and conservation strategies, such as …
