Biodiversity Effects on Species Richness
Primary tabs
Overview:
This dataset summarized the effect of experimentally reducing species richess has on abundance or biomass of the focal group, abundance or biomass of the focal group's primary resource, and/or the depletion of resources by that trophic group.
Dataset Location: Ecological Archives
Methods: Experimental studies were chosen for their focus and manipulation of species richness as a measure of biological diversity, accounting for 85 papers. (See Cardinale, B. J., D. S. Srivastava, J. E. Duffy, J. P. Wright, A. L. Downing, M. Sankaran, and C. Jouseau. 2006a. Effects of biodiversity on the functioning of trophic groups and ecosystems.

Data Collected: species richness, experiment descriptors, top-down or bottom-up trophic manipulation, diversity effect
Best practices: Cells with "." indicate that the information is not available or not relevant. Cells left blank indicate that the information may or may not exist, but has not been collected.
Additional considerations: These data are part of a meta analysis dataset, and as a result are highly derived. Before reusing this data, researchers should thoroughly read the metadata and paper regarding this data to determine if the decisions made in compiling this dataset are compatible with their question.
