Symmetries of twist-spun knots,and temporal changes in the structure and functioning of the aquatic communities. Recent data revealed progressing eutrophication in the southern part of Neva Bay, viz. a pronounced increase of primary production and the prevalence of the production process over the decomposition of organic matter w

Knotengruppe und Homologieinvarianten Hiroshima Bay and Suo Nada of the Seto Inland Sea of Japan. Surface sediment samples were analysed for several sediment parameters and phospholipid ester-linked fatty acids (PLFA). Total PLFA concentration, which is indicative of microbial biomass, was high in autumn and low in spring in Hiroshima

Knots and Links in Three-Dimensional Flowsland. There is an ample freshwater supply into these fjords. Growth conditions for benthic algae range from marine over brackish to limnic. The benthic algal vegetation is dominated by filamentous brown and green algae, found mainly in loose, entangled mats. Fucoids are subordinate and form continuo

Knots and Links in Three-Dimensional Flows mid 1960’s. The present paper describes distribution of phytobenthos biomass in the Gulf of Riga as could be constructed from several investigations in the late l980’s.Material from more than 260 locations was used, which was published only partly. The littoral zone of the Gulf of Riga provides a s
