CYANOBACTERIA AND DIATOMAL ALGAE IN DIFFERENT ECOTOPES COMMUNITIES OF THE COASTAL AREA OF SEVASTOPOL (BLACK SEA)

The purpose of this investigation is to study the biodiversity and occurrence of cyanobacteria and microalgae, as well as their ability to form microcolonies in cultivated samples from various ecotopes of the Sevastopol coastal area. The method of laboratory cultivation was used in the work. The study of the communities revealed a significant variety of forms of photosynthetic organisms. Many of them could form regulated structures (microcolonies), which was important for the existence of organisms under certain conditions
