SOME FEATURES OF VARIABILITY OF BIOMETRIC INDICATORS OF JUNIPERUS OBLONGA IN DAGHESTAN
An analysis of approximately 4,000 individuals across twenty cenopopulations of oblong juniper (Juniperus oblonga M.Bieb.) in Daghestan was conducted at altitudes ranging from 50 to 1950 meters above sea level. The study area spanned from the Tersk-Kuma Lowland (Nogai District, Sosnovka tract) in the north to the spurs of the Khultaydag Range in southern Daghestan. The height and diameter of J. oblonga shrubs were measured, and a biomorphological index was calculated. The biometric parameters of the shrubs were analyzed in relation to solar radiation and the hypsometric profile of both anthropogenically terraced and non-terraced landscape slopes. It was established that the wide range of variability in J. oblonga shrub parameters is associated with its ecological plasticity. This plasticity enables the species to adapt not only to changes in the general ecological conditions of landscapes but also to variations in slope aspect and different elements of the hypsometric profile within the biotope.
