    This article presents the hydrochemical characteristics of Karatal, Ak-Su and Lepsy rivers, hydrological regime and results of hydrobiological research. It also presents the results of studies on the formation of water quality in these rivers at present. As a result, an assessment of the ecological status and water quality was carried out using information and analytical materials from RSE Kazhydromet and Annual data on surface water quality of Kazakhstan. Monitoring was conducted from 2015 to 2020 and included changes in water temperature, dissolved oxygen content, pH values, mineralization levels, as well as main inorganic constituents such as cations and anions. The influence of natural factors on chemical composition of these rivers was also considered.

    This article presents the results of a comprehensive assessment of the ecological status of populations of the rare endemic species Schmalhausenia nidulans native to the high-mountain regions of the Northern Tien Shan. The aim of the study was to investigate the current state of the species populations by analyzing their numbers, ontogenetic structure, morphometric parameters, and anatomical features. Two natural populations of the species were examined: the first population, located on the Uzynkara Ridge at an altitude of 3003 m above sea level, and the second population, growing on the Ile-Alatau Ridge at an altitude of 3260 m above sea level. During the field research, the population size, age structure, and morphological traits of individuals at the juvenile, immature, virginal, and generative stages of development were studied, and an anatomical analysis of the stem structure was also conducted.
