Abstract
Different models of how species are arranged on an environmental gradient result in different amounts of clumping of the species boundaries. A statistical test of the degree to which the boundaries are clumped is presented here and a measure of the variability of inter-boundary distance is discussed. To complement the tests, a method for detecting those portions of the gradient on which the boundaries are most clumped together is described. In addition, a test of the extent to which the upper and lower boundaries of species are intermingled is presented. The methods are illustrated using the arrangements of seaweed species on rocky shores.This publication has 1 reference indexed in Scilit:
