WebFeb 1, 2003 · Specifically, Hubbell set out to create a model in which all of the factors influencing community composition—births, deaths, immigration, and (on longer time scales) speciation—interact to produce the commonly observed empirical patterns of diversity and distribution of abundance. WebAs θ gets larger, the distribution becomes increasingly s-shaped (log-normal) and, as it approaches infinity, the curve becomes flat (the community has infinite diversity and species abundances of one). Finally, when θ = 0 the community described consists of only one species (extreme dominance). cheltenham youth football league

WebDominance/diversity curves, displaying the relative abundances of the species within a community, have often been constructed from field data. Several ecological and statistical models of dominance/diversity have been proposed, to explain the curves. Yet, rarely have curves of different models been fitted to field data.
