  "Description": "Provides a flexible, extendable representation of an\necological community and a range of functions for analysis and\nvisualisation, focusing on food web, body mass and numerical\nabundance data. Allows inter-web comparisons such as examining\nchanges in community structure over environmental, temporal or\nspatial gradients.",
