Biodiversity Effects on Ecosystems, Communities, and Populations


This metadataset describes the effects of biodiversity on response variables of experimental studies published between 1974-2004.

Dataset Location: Ecological Archives

Methods: Data was extracted from 137 published articles, containing 761 measurments, for analysis within this study to determine the effect of biodiversity loss on variables relevant to agriculture, forestry, fisheries, and conservation. Simple regression or ANOVA were used to measure biodiversity effect. The shape of the relationship was also described. Additionally, studies were asigned general descriptors to classify them into categories. (See Balvanera, P., A. B. Pfisterer, N. Buchmann, J. S. He, T. Nakashizuka, D. Raffaelli, and B. Schmid. 2006. Quantifying the evidence for biodiversity effects on ecosystem functioning and services. Ecology Letters 9:1146–1156.)

Best practices: Missing data code NA.

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.
