Shibliak or maquis? On the introduction of Quercus ilex L. in phytocoenosis of the Southern Coast of the Crimea

Abstract

Here we tried to answer the question about what will happen in the vegetation cover under current warming trends, and how in phytocenoses will native plant behave - summergreen pubescent oak ( Quercus pubescens Willd.) and the newcomer from the culture - evergreen holm oak ( Quercus ilex L.) that escaped from introduction sites. The work is based on geobotanical descriptions (14) performed when mapping vegetation of the lower vegetation belts between Foros and Gurzuf. Using "Ecodata" database containing information on the position of species on the gradients of environmental factors and "Pover" processing program, evidence of successful adaptation of holm oak to natural and disturbed phytocenoses in the western part of the Southern Coast was obtained
