moss


Binary, symmetrical, ordered, predator:prey matrix. Column n represents the same species as row n. All species present in the food web are represented, including basal resources. Zeroes denote the absence of a trophic interaction. A one denotes that the species in the column consumes the species in the row.


datasets

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.
