ON THE CHARACTERISTIC OF COENOPOPULATIONS OF SOME INVASIVE SPECIES OF ABKHAZIA
Abstract
The article considers the processes of invasion into ecosystems of the Caucasian region and states their low resistance to the introduction of alien species of plants. The search for the invasion centers and researches of biological features of invasive species were conducted in 2015 in three eastern areas of the Republic of Abkhazia. The paper provides the data on biology of 6 invasive species from Asteraceae family — Ambrosia artemisiifolia L., Gentaurea iberica Trev., Conyza graminifolia Sreng., Phalacroloma annuum (L.) Dumort., Galinsoga parviflora Cav., Solidago virgaurea L. The research shows high density (up to 176 specimen/m2) and the share of most species in communities (to 87%) thus demonstrating their invasive success. Further resettlement of species in ecosystems of Abkhazia and their dominance in phytocoenosis are predicted.
