The sterol composition of the brown algae Stilophora rhizodes (Turner) J. Agardh, Punctaria latifolia Grev. and Punctaria plantaginea (Roth) Grev. from the Black Sea was investigated. Fifteen sterols were identified in the sterol fractions. The main ones were cholesterol and 24-methylenecholesterol. Characteristic for brown algae, fucosterol was present in low concentrations. The results obtained were compared with recent data for the sterol composition of other Black Sea brown algae. Some conclusions concerning the evolutionary position of brown algae are made.

Abstract For the first time the concentration of 26 macro- and microelements (Na, Mg, Al, Cl, K, Ca, Sc, V, Mn, Fe, Co, Ni, Zn, As, Br, Rb, Sr, Sb, I, Cs, Ba, Sm, Nd, Ag, Au, and U) in the thalli of brown algae Cystoseira barbata C. Ag. and Cystoseira crinita (Desf.) Bory was determined by instrumental neutron activation analysis (INAA), Sevastopol region, south-western Crimea, the Black Sea. The observed peculiarities of the elemental accumulation showed that Cystoseira spp. can be used as a biomonitor of coastal waters pollution in the study area.

The associations and ecological conditions of the existence of modern diatoms of the North-West (Pridneprovsky), Prikerchensky and Eastern regions of the subtidal zone of the Black Sea are considered. Based on the unity of the composition of the Present and Sarmatian-Meotian diatom flora, an attempt has been made to model some of the ecological c situation of the Late Miocene Euxinian basin.
