The obtained results permit to add the dating on 90Sr to the 137Cs method on estimation of the Black Sea bottom sediment accumulation rate earlier developed in RChBD (Radiation and Chemical Biology Department).
State of coenopopulation of cystoseira on some parts of the Crimean coast with different anthropogenous loading. (A. V. Prazukin , S . A . Kovardakov )
ABSTRACT: Researches show that Cystoseira crinita (Desf.) Bory has large adaptive and restoration potential.

After elimination of anthropogenous influence the Cystoseira crinita population can be completely restored during subsequent 15 - 20 years.
