9.1 the difficulty of inferring process from pattern

This is an implementation of the model described in

Cale WG, Henebry GM and Yeakley JA 1989 Inferring process from pattern in natural communities. BioScience, 39, 600-605.

which demonstrates the challenges involved in inferring processes from patterns.

8.1 leGUME (the Grand Unified Model of Everything)

This is the model presented in Chapter 8 of the book, which combines elements from many of the building-block models discussed in earlier chapters.

You can see a fairly typical example of long-term survival of the island colonisers in the video.

Details of the model are in Chapter 8 and additional information not included in the Chapter can be found here.

7.1 Ruckelshaus model of dispersal

This is an implementation of the model of the relationship between dispersal and fragmentation described in

Ruckelshaus M, Hartway C and Kareiva PM 1997 Assessing the data requirements of spatially explicit dispersal models. Conservation Biology, 11, 1298-1306.
