Hello, Is there a diversity index similar to the 'contribution diversity approach' contribdiv()in vegan that reflects only  the compositional 'distinctiveness' of a site within a region. contribdiv()combines 'distinctiveness' with a within-site diversity measure such as richness, I on the other hand am looking for an index that measures only the relative number of species within a site that are 'distinct' or 'unique' within a region.

Cheers,
Burak
