Mutual Influence of Cyanobacteria and Green Algae in Cocultures Using the Example of <i>Dolichospermum spiroides</i>, <i>Planktothrix agardhii</i>, and <i>Chlorella vulgaris</i>

First Data on Cyanotoxins and Genes of Their Biosynthesis in the Phytoplankton of the Mesotrophic Lake Pleshcheyevo (Russia) During the Bloom Formation of Cyanobacterium <i>Gloeotrichia echinulata</i>

Decreased Viability and Changes in Sex Ratio in the Offspring of <i>Danio rerio</i> as a Result of Exposure to 2,2 ’ ,5,5 ’ -tetrachlorobiphenyl (PCB 52) on Producers During the Prespawning Period

Influence of Migrations of Some Azov-Black Sea Basin Fish Species on Their Invasion with the Nematode <i>Hysterothylacium aduncum</i> in Different Seasons
