Taxonomic Composition and Physiological Activity of Phytoplankton in Biological Ponds of the Bukhara Region

An important part of aquatic ecosystems is aquatic biota, represented by a mosaic of interconnected biocenoses that occupy all possible biotopes in streams and reservoirs: they inhabit the water column (plankton), the thickness and surface of the soil (benthos), overgrow the surface of solid rocky substrates washed by water or settling on the surface of macrophytes and in the turf of water moss (periphyton). Their species composition and structure are entirely determined by climatic and landscape conditions prevailing in drainage basins or directly in river corridors and coastal zones of lakes.
