摘要

The peculiarities of the structure of the population of the brown alga Fucus vesiculosus in East Murman at different combinations of abiotic factors were studied. Salinity below 10‰ high surf activity reduced the average life span of the plants (to 1 year) and caused a significant predominance of female specimens (60-90% of the fertile specimens). The proportion of female specimens increased with age. The greatest average age (3 branchings) and the highest survival of F. vesiculosus occurred in the wave-protected parts of bays. The distribution of F. vesiculosus was related to water movement intensity, salinity, and substrate type. The size-weight characteristics of F. vesiculosus thalli were decreased during maximum salinity fluctuations. The optimal conditions for this species were those existing on a weakly protected shore with short-term fluctuations of salinity (24-25‰).
