F. aThe assembly of species communitiesbchance or competition? c1979 aWe challenge Diamond's (1975) idea that island distributions are determined predominantly by competition as canonized by his "assembly rules". We show that every assembly rule is either tautological, trivial, or a pattern expected were species distributed at random. In order to falsify a null hypothesis stating that the distributions are generated by species randomly and individually colonizing an archipelago. aAssembleia rege aAssembly rules aBird communities aCompeticao aCompetition aComunidade de passaro aDistribuicao de especies de ilha aExclusive distribution aIsland species distribution aPar de especies aSpecies pair1 aSIMBERLOFF, D. tEcologygv.60, n.6, p.1132-1140, Dec. 1979.
