The aim of the research work is to define taxonomic content of the algoflora of the Andijan water reservoir, and justify its seasonal changes.
The object of the research is algal flora of Andijan reservoir.
Scientific novelty of the research is as follows:
first of all, 418 species were detected and their conspectus was developed on the bases of the comprehensive inventarization of the algoflora of the Andijan water reservoir; for the first time, 10 species previously not described for the flora of Central Asia, were detected in the algoflora of the Andijan water reservoir: (Peridinium limbatum (Stokes) Lemm., Glenodinium ambiguum Thomp., Trachelomonas labiata Teiling, Trachelomonas conica Playf, Elakatothrix spirochroma (Reberd.) Hind., Cosmarium subtruncatellum Gronbl., Xanthidium variabile (Nordst.) W.et. G.S. West, Chodatella cingula (Schmit.) Fott., Coelastrum scabrum Rein., Kirchneriella cornuta Korsch.); comperative analyses of the algoflora of the Andijan water reservoir with the algofloras of several other Uzbekistan resourvoirs were conducted, and common species were detected along with specific species for the Andijan water reservoir; seasonal changes in the content of the algoflora were detected, and the difference was 40 (13,07%) between the number of the species in spring and summer seasons, 45 (13,0%) between summer and autumn seasons, and 228 (75,7%) between autumn and winter seasons; the ecological groups of the algoflora, plankton, plankton-bentos and bentos groups, inhering of the algoflora species according to their adaptivity to the water salinity and temperature, and the number of the indicator saprobe species were defined; for the first time, digital data base on the modem content of the species of the Andijan water reservoir was developed and practically implemented.
