ВИТАЛИТЕТНОЕ СОСТОЯНИЕ ОСОБЕЙ ONOBRYCHIS MAJOROVII GROSSH. В ЗАПОВЕДНОЙ САРЫКУМСКОЙ (ДАГЕСТАН) ЦЕНОПОПУЛЯЦИИ

Abstract

This article is devoted to the study of Onobrychis majorovii coenopopulation located in reserve Saricum. For coenopopulation study was used the method of Yu. A. Zlobin. In research morphometric and allometric parameters were considered. Studies have allowed to get some idea not only about the features of the vitality spectrum of individuals, but also about the conditions for the implementation of processes of their growth and development. As the research results showed, the characteristics taken for accounting are characterized by a wide range of variability from medium to very high. When distributing individuals by size classes, for most characters, a predominance of individuals in the medium-sized class was noted, although the prevalence of a small-sized class of individuals was recorded for five characters, which raises some concerns about the state of the studied coenopopulation. In general, by all indications, the mediumsized class prevails and the prosperous nature of life processes in individuals of the studied coenopopulation is calculated. However, the degree of prosperity of the studied coenopopulation is extremely low, which suggests that the conditions for the existence of coenopopulation are far from optimal. Based on previous studies and the discovery of the regressive nature of life processes in individuals of the studied species in the Saricum coenopopulation, we can conclude that it is unstable. This may be a consequence of exposure to extreme natural factors and / or the influence of anthropogenic stress.
