  3. 2. Species richness correlations between taxa calculated from species-area relationships

    University essay from SLU/Dept. of Entomology

    Author : Karin Ström; [2006]
    Keywords : species richness correlations; meta-analysis; species-area relationships; taxonomic distance; biodiversity;

    Abstract : Predicting the species richness of certain taxa from the richness of others could be of great value in biodiversity conservation. If we know how the species richness of groups of organisms correlate to each other under different circumstances, inventories of only a few well-known taxa could be enough to establish the biodiversity values of different areas.
