This research aims to study dynamics cyanobacteria population in the
Room reservoir (in the south Syria: Sweeda), which affected by water quality
environmental conditions, and seasonal. 17 genera where identified and their
dynamics studied monthly
during 2007, calculate the biomass of the prevail
genera. The bloom was occurred in October, and the value of diversity
coefficient was the highest in July in the Room reservoir, but didn't occurred in
the Jouelen reservoir.
