Cascade Food Web Model

Usage

cascade(S, C)

Arguments

S	Number of species in the community.
C	The connectance, or fraction of realized links in the food web.

Value

The adjacency matrix of a cascade model food web. Species are arranged along a niche axis and may consume any species with a niche value less than their own with a fixed probability of 2CS/(S-1), creating a triangular matrix.
