DescriptionIn virtually all ecological communities around the world, most species are represented by few individuals, and most individuals come from only a few of the most common species. Why this distribution of species abundances is so regularly observed among different taxonomic sets in geographically diverse systems is a question that has received considerable theoretical and empirical investigation (Preston 1948, 1962; Harte et aL 1999; Hubbell. 2001). Understanding the mechanisms leading to the pattern of few common and many rare species extends beyond basic interest in how natural communities are assembled. It is also of great practical importance to conservation science since human uses of ecosystems can greatly affect the pattern of commonness and rarity in the biota inhabiting those same ecosystems (Lubchenco et. al. 1991).
