On the statistical study of proportional gain of taxa by the Introduction of nonnatives in the local flora: a paradigm shift

摘要: The De Candolle-Darwin naturalisation theory offers the mechanism for generic enrichment in natural floras. Is the mechanism sufficient for the explanation of local enrichment phenomena? A previous moment and product moment based statistical study of Kentucky's natural flora found the naturalisation theory based mechanism insufficient. Is that finding an artefact, or has the relevance of the theory reached its limit in that locality? We reanalysed the data within a new statistical framework using tensor algebra and fractal geometry scalars. The results support the previous finding: the naturalisation theory based mechanism cannot explain the enrichment phenomenon in the Kentucky flora.
