摘要:The structure of a community is determined largely by the relative abundances of its constituent
species. Biological surveys that aim to describe the diversity of a community are expensive to
undertake and identifying the species present is time consuming, labour intensive and requires
specialised expertise. The resulting dataset is large and difficult to analyse using standard
methodology as the assumptions of the statistical models such as normality and homogeneity
of variances are rarely met. Finding patterns in such a large dataset and generating a useful
summary of complex relationships is challenging, however, over the last decade there has
been development and refinement of statistical tools and methodological approaches (Quinn &
Keough 2002) that now make this task much simpler.
