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