Abstract
The distribution of invasive species is associated with a change in the distribution boundaries of individual taxa and non-taxonomic groups, with its development of new biotopes, change in the structure and functioning of individual ecosystems. Invasive species in Russia is a wellknown phenomenon. Over the past 50 years, more than 10 herbivorous species have been discovered which are classified as quarantine species. In the near future, the appearance of new aggressive species such asDiabrotica virgifera virgifera Le Conte – western corn bug,Popillia japonicaNewm – Japanese beetle and others is expected.
Highlights
In the new climatic conditions, the adventive species in acclimatization phase undergoes microevolutionary changes in the genetic and phenetic structure
The adventive species is included in the trophic chains of the ecosystem, forming a complete food chain and the introducer becomes a constant component of the biocenosis consortium [4,5]
Several new invasive species have been recorded for the fauna of the Krasnodar Region
Summary
In the new climatic conditions, the adventive species in acclimatization phase undergoes microevolutionary changes in the genetic and phenetic structure During this period, the introducenter rapidly multiplies due to the redistribution of energy resources [1,2] and dominates in biogeocenoses due to the lack of constant components of consortia in cenoses that hinder its development in the native range. The adventive species is included in the trophic chains of the ecosystem, forming a complete food chain and the introducer becomes a constant component of the biocenosis consortium [4,5]. In this regard, it is very important to distinguish invasive species from indigenous representatives of fauna, which is very poorly studied. All partners of the Convention on Biological Diversity have committed themselves to take administrative measures to reduce the negative impact of invasive species on indigenous ecosystems
