Ogureeva G.N., Bocharnikov M.V., Suslova E.G. STRUCTURE OF THE CRIMEAN-NOVOROSSIYSK OROBIOME (THE UTRISH-TUAPSE VARIANT) BOTANICAL DIVERSITY // Arid ecosystems. 2020. V. 26. № 4 (85). P. 10-17. | PDF
Based on the concept of ecosystem diversity, a regional assessment of the Crimean-Novorossiysk orobiome is given. Orobiome is considered to be a strong unit for inventory and analysis of mountain biodiversity. On the example of the Utrish-Tuapse geographical variant of the orobiome (the Northwest Caucasus), the altitudinal-belt structure of the vegetation cover is revealed, according to which the spatial differentiation of flora and plant communities are formed. A quantitative evaluation of biota and abiotic indicators characterizing the botanical and geographical traits of the orobiome is given. The spectrum of altitudinal zonality of vegetation is determined, a quantitative assessment of floristic diversity by the belt is given, and some features of the spatial structure of community diversity in mountainous areas are revealed.
Keywords: biodiversity, altitudinal zonation, orobiome, mapping, the Abrau Peninsula, Sub-Mediterranean.

The article is related to the patterns of landscapes and vegetation cover spatial organization on the Abrau peninsula within the “Utrish” natural reserve and the adjacent territory, which are expressed through the landscape structure of the mountain territory. Ecological and topological profiling and large-scale mapping of vegetation and landscapes made it possible to assess the spatial diversity of unique sub-Mediterranean ecosystems according to geological and geomorphological conditions, including the absolute heights, exposure and steepness of the slopes, climate features and the influence of the sea. The specificity of environmental conditions at different altitudes is reflected in the structure of phytocoenotic diversity, which causes the formation of two altitudinal sub-belts within the seaside belt, as well as the change in the typological composition of forest, sparse forest and shrub communities at different levels of phytocatena.
