- Оригинальные версии: Naturalized Alien Species in the Floras of the Middle Part of European Russia: Homogenization or Differentiation?
- Аннотация: Human activities, including biological invasions, cause large-scale changes in the distribution of organisms, one of the consequences of which is biotic homogenization, revealed to varying degrees for different biotic groups. Russian researchers use the term "unification of biota" to explain the increasing in taxonomic similarity between regions as a result of invasions, but there are no quantitative estimates of this phenomenon. The change in the similarity or difference in regional floras taking into account naturalized alien species in them is estimated for the regions of the middle part of the European Russia on the basis of a comparison of the Jaccard similarity coefficients. Inclusion of naturalized plant species in flora increases their differences due to differentiated naturalization depending on natural conditions. However, the presence of different structural groups affects the similarity/differences in floras differently. The annual/biennial species have a greater homogenizing effect unlike herbaceous perennials and tree species, species alien in European Russia (biogeographically associated with the floras under analysis) unlike alien to European Russia species (with natural ranges outside the territory of European Russia). The analysis does not correspond to the opinion of Russian authors on unambiguous "unification of biota" as a result of alien species introduction and confirms the point of view of some researchers that biotic homogenization is not an inevitable fact in biological invasions.
