The comparative characteristics of algal flora of Dam-Ashi, Romidon, Upper-Northern Tashkent channels, of the small puddles and fish ponds of Dam-Ashi

摘要

For years 1988-1995 algalogical comparative investigations ill Dam-Ashi, Romidon, Upper-Northern Tashkent channels, of small puddles and fish ponds of Dam-Ashi are being carried out. The 222 species belonging to 68 genera, 39 families, 19 orders, 11 classes and 5 divisions were recorded. Bacillariophyta are the dominated algae (111 species; 50%), Chlorophyta follows them (57; 26,0%), Cyanophyta (40; 18,00), Euglenophyta (13; 5,55%), Chrysophyta (1; 0,45%) are tile next. The 143 species are met in all channels (Dam-Ashi-93, Romidon-31, U.-N. Tashkent-82), 14-in the small puddles and 122-in the fish ponds. 29 species are similar to algal flora of Dam-Ashi and U.-N. Tashkent channels and coefficinet community of flora (CCF) according to Jaccar formula is 0,19.
