Measurement BIOHabitatMetric035 The percent of the sample made up of organisms that consume other organsims. Y chmo483 06/04/2012
Measurement BIOHabitatMetric036 The number of taxa in the sample representing organisms that consume other organisms Y chmo484 06/04/2012

Measurement BIOHabitatMetric045 Compares diversity by accounting for both richness and evenness of the sample. Generally this metric scores between 0 and 4.5. A higher score represents higher diversity. It is not used to compare sites, however since it is affected by changes in both the number of taxa and the relative abundance of those taxa. Y chmo477 06/04/2012
Measurement BIOHabitatMetric046 Compares diversity by accounting for both richness and evenness of the sample. Generally this metric scores between 0 and 4.5. A higher score represents higher diversity. It is not used to compare sites, however since it is affected by changes in both the number of taxa and the relative abundance of those taxa. Y chmo478 06/04/2012
Measurement BIOHabitatMetric047 Measures diversity by reporting the chance that any two randomly drawn individuals from a sample are the same species. This measure is heavily influenced by relative abundance of each taxa. The measure scores between 0 and 1, with a more diverse community reflected by a score close to 1. Y chmo479 06/04/2012
