visualisation and analysis of food web networks
Description
Calculates twelve commonly-used, basic measures of food
web network structure from binary, predator-prey matrices:
species richness, connectance, total number of links, link
density, number of trophic positions, predator:prey ratio, and
fraction of carnivores, herbivores, top species and
intermediate species. Employs food web language in the code
and output, translates between a couple of common food web
formats, can handle food webs consisting of multiple levels,
and can automate the analysis for a large number of webs. The
program produces 3-dimensional graphs of high quality that can
be customized by the user.
