Abstract
In the article, the authors present for the first time the progressive and regressing algae of the genus Navicula Bory (Bacillariophyta) the water bodies of the Chirchik River basin. The research was carried out during 2005-2012, 2018-2020 yy. with the National Universities of Uzbekistan and the Institutes and Botany of the Academy of Sciences of the Republic of Uzbekistan. 122 species and varieties of algae of the genus Navicula Bory have been identified. Among them, new species for water bodies, saprobic indicators were noted, the seasonality of algae was studied. The main new ideas the article are as follows: among the algae found, it is progressive algae 6. They are found very often, in or mass one field of view of the objective, their frequency of occurrence is equal to 5, 7, 9 points and is considered a resistant species various environmental conditions, being a promising algae with full life. 96 - less progressive algae, occurs rarely, the occurrence is equal to 5, 3 points and is less resistant and less promising algae with a sex life. 20 species and varieties are regressing algae, water bodies it meets only units (single), the frequency of occurrence is equal to 1 (one) point and is considered unstable algae of the investigated water bodies, the future, there is a threat to safety and Not Live! (No Life!) Needs protection. It was proposed to include the next issue of the Red Book of the Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan, as well as to accept and include the list of protected microorganisms water bodies of Uzbekistan under the Committee for Ecology and Nature Protection of the Republic of Uzbekistan.
Highlights
The topic "Progressing and regressing microalgae of the genus Navicula Bory..." is considered a very relevant idea, which raises these issues for the first time in Uzbekistan and meets one of the main tasks of scientific research of the global problem "Man and the Biosphere"
The collected algological samples are stored in the algological collection of the Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan, partly at the Department of Ecology of the National University of Uzbekistan, and the list of progressive and regressing microalgae of the genus Navicula Bory is stored in the "Database of Algological Collections" and "TASH" of the Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan
122 species and varieties of microalgae of the genus Navicula Bory have been identified for the water bodies of the basin
Summary
Algal species of the genus Navicula Bory are considered rich in biodiversity [5, 13, 16, 23]. Participates in self-purification and bioindication of water quality in reservoirs. The biological diversity of algae, rational use and their protection is currently an urgent problem. In this regard, the topic "Progressing and regressing microalgae of the genus Navicula Bory..." is considered a very relevant idea, which raises these issues for the first time in Uzbekistan and meets one of the main tasks of scientific research of the global problem "Man and the Biosphere"
