Spatial Ecology-Introductory Lectures
***=required reading
 

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.  Some newer references would be covered in the Hansk and Gaggiati book.

Lecture 2.  Diffusion approaches - introduction. Our goal here will be to present the diffusion models as a way of expressing spatial structure and looking at spatial spread, 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.  The review in Hastings et al., 2005 cotnains numerous references that I do not repeat here (see in particular ndow et al.).  This topic is a superb example of the theme of what is the level of  'relevant' detail introduced in the first lecture.  Also, we explicitly focus on the idea of relating macroscopic behavior (population level) to microscopic behavior (individuals), and to some simple ideas concerning matching of data to model.
