Overview

More than 100 food web matrices (multiple predators/prey Excel worksheets) are included with the javaFOODWEB tool. The predator-prey matrices are converted to symmetrical predator matrices in order to investigate the competition for resources. After manipulating these transformed matrices, the patterns within the community ecology of niche-spaces and trophic hierarchies are visualized.
