Central Caucasus

ON THE SYNTAXONOMY OF SOME PHYTOCENOSES IN MOUNTAIN AND PIEDMONT ECOSYSTEMS OF THE CENTRAL CAUCASUS (WITHIN KABARDINO-BALKARIA)

Authors: Tzepkova N. L.

Three associations (Carici michelii-Bromopsidetum ripariae ass. nov., Amorio ambiguae-Alchemilletum orthotrichae ass. nov., and Cicerbito macrophyllae-Aethusetum сynapii ass. nov.) have been distinguished and characterized as a result of our ecological and floristic classification of phytocenoses in the mountain and piedmont ecosystems of Kabardino-Balkaria (the Central Caucasus) within the Tersky and Elbrussian variants of vertical zonation.

Ecologo-biological characteristic of natural steppe biogeocenoses in the Central Caucasus (the Terskiy variant of vertical zonation, Kabardino-Balkaria)

An ecologo-biological characteristic of the natural steppe biogeocenosis components in Kabardino-Balkaria (within the Terskiy variant of vertical zonation) is given. The research results of biological features of common chernozem calcareous soils (humus contents, enzymatic activity, and soil respiration intensity), their spatial and profile distribution combined with basic ecological factors are represented.
