Dr. Poroshat Yazdanbakhsh (Rollins College) will present “From Slow to Fast Dispersal: Impacts on Species Persistence and Infectious Disease Invasion“ at this week's Mathematical Biology Seminar.
Abstract: In heterogeneous environments, populations of species and infectious diseases are often distributed across patches with different environmental conditions that are connected through dispersal. As dispersal can play a crucial role in determining whether populations and pathogens persist or go extinct in such spatially structured systems, understanding how movement among patches interacts with environmental heterogeneity is a central problem in ecology and epidemiology.
In this talk, we use analytical tools from perturbation theory and group inverse to investigate how slow and fast dispersal influence population dynamics. Our analysis highlights the combined effect of environmental heterogeneity, network connectivity, and dispersal rates.
