How does landscape heterogeneity affect population dynamics?

Mathematical models for population dynamics have a long
history in biomathematics. They are tools to explore the effects of
birth and death, species interaction, landscape quality and spatial
movement on the persistence, spread and spatial distribution of a
species. One particular question is how spatial variation in landscape
attributes affects the dynamics of populations, for example in the
context of species invasions. A relatively recent approach to this
question divides a landscape into « patches » and incorporates small-scale
individual movement information to predict large-scale population
dynamics.
In this talk, I will review several aspects of this growing body of
literature. I will include empirical evidence, model derivation, basic
model outcomes, analytical challenges and some future ideas. The talk is
aimed at a general applied mathematics audience.
