Comments on Ricotta: Ecological diversity and biodiversity as the tool for conservation planning Sarkar Sahorta Biodiversity and Biocultural Conservation Laboratory, Section of Integrative Biology and Department of Philosophy, University of Texas at Austin, USA Corresponding author: sarkar@maiI.utexas.edu
Online published on 5 April, 2012. Abstract Ricotta argues against the existence of a unique measure of biodiversity by pointing out that no known measure of adiversity satisfies all the adequacy conditions that have traditionally been set for it. While that technical claim is correct, it is not relevant in the context of defining biodiversity which is most usefully measured by β-diversity. The concept of complementarity provides a closely related family of measures of biodiversity which can be used for systematic conservation planning. Moreover, these measures cannot be replaced by summary statistics but must rely on inventories of biodiversity surrogates at candidate sites for conservation. Top Keywords α-diversity, β-diversity, biodiversity, complementarity, systematic conservation planning. Top | |
