This paper discusses the measurement of taxonomic diversity of a given community or set of species. First, given D, the matrix of pairwise distances between species, I propose to summarize taxonomic diversity through Rényi's information-theoretical parametric formalism on D. In this way, a family of taxonomic diversity indices is obtained which shows different sensitivity to the presence of species with different levels of taxonomic distinctness. The adequacy of information-theoretical indices for quantifying taxonomic diversity is discussed.

Abstract
This paper discusses the measurement of taxonomic diversity of a given community or set of species. First, given D, the matrix of pairwise distances between species, I propose to summarize taxonomic diversity through Rényi's information-theoretical parametric formalism on D. In this way, a family of taxonomic diversity indices is obtained which shows different sensitivity to the presence of species with different levels of taxonomic distinctness. The adequacy of information-theoretical indices for quantifying taxonomic diversity is discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
