Pr. Makarevich et al., Basic tendencies in the structural dynamics of phytoplanktonic and benthiccommunities in the Sea of Azov, RUSS J ECOL, 31(6), 2000, pp. 411-414
New data on the present-day state of planktonic and benthic communities in
the Sea of Azov were obtained during an expedition organized in 1997 and 19
98. The analysis of their species composition and quantitative indices of b
iomass and abundance revealed two obvious tendencies in the structural dyna
mics of biocenoses. The first is directly produced by disturbances of the e
nvironment under anthropogenic impact, and the second reflects the effect o
f global natural factors.
