BIO205H5 Lecture Notes - Lecture 13: Metapopulation
Document Summary
All models are wrong, but some are useful - quote by a statistician. Areas are not equally distributed and not the same in quality. We have to talk about this patchness for habitats. If forests are close, the movement would be more frequent. Note: the top right and bottom right patches, no chipmunks are moving between them. Lots of movement: subpopulations are synchronized (if one goes up, the other one goes up e. g. similar environmental conditions. We want to describe with a model for metapopulation dynamics. If we take out the 1, we would be calculating the proportion of unoccupied patches. Some things make patches of a different quality. Patch size would relate to probability of colonization (proportional). This is a deterministic model (recall from previous lectures) - only find 1. Assume matrix surround habitats don"t differ in th way that animals can move through. Patches of suitable habitat are surrounded by matrix of unsuitable habitat.
