摘要：Species-area relationship (SAR) is a tenet in ecology. Unfortunately, even in very recent works researchers take for granted what they shouldn’t take for granted, that is to say the fractality of such relationship. This is a serious mistake, both from a theoretical and methodological viewpoint. Unvealing non-fractality or multifractality of species-area relationship could mean a lot for conservation purposes of rare and not rare species. Detection of discontinuities in SAR may indicate significant changes in the processes that generate and maintain biodiversity, in particular with regard to different degrees of density-dependent events or interspecific interactions. Methodological tools are already at hand, so I invite scientists to employ them as soon as possible.
