Simple Simulation of Salmon Life Cycle
This is a simple model that simulates the life cycle of a salmon population as it migrates from the stream, to the ocean, and back to the stream. Although the data and model structure are fictional, it does provide a simple example of how such a model could be constructed.
This model is based on an example presented in "Modeling the Environment" by Andrew Ford (published by Island Press). http://islandpress.org/ip/books/book/islandpress/M/bo8014682.html
