Spatial Ecology—Introductory Lectures
Once again, we begin with the classics before taking on the more modern approaches.
Lecture 1. Patchy environments.
The first approach we have to looking at spatial questions is to begin with the classic work of Huffaker, and models of this work. We will look first at the results of Huffaker’s system, and then develop models, in analogy to our work on epidemic modeling, that can be used to help understand these dynamics. This work will set the basis for our future discussions of metapopulations.

Lecture 2. Diffusion approaches – introduction. Our goal here will be to present the diffusion models as a way of expressing spatial structure and to explore the assumptions underlying the model. The examples in Kareiva (1983) will be used to look at the adequacy of the model. The use of the approach to ask other biological questions will be emphasized in future lectures.
