A possibility of applying a morpho-functional approach in estimating structural and functional organization of benthic algal communities with the aim of performing express diagnostics of tropho-saprobic condition of coastal ecosystems is discussed. In determining the tropho-saprobic category of ecosystems, indices of surface of phytocenoses, as well as of specific surface of populations have been used as quantitative criteria determining morpho-functional structure of the benthic vegetation. Classification of trophic levels of aquatic environment has been suggested. It is based on the following surface indices of benthic algae communities: xenotrophic < 5; oligotrophic 5−19, mesotrophic 20−40; eutrophic 41−70; polytrophic 71−120; hypertrophic >120 (units). Empirical values of the surface indices of phytobenthos for ecosystems with different trophic levels have been presented. Based on the morpho-functional structure of phytobenthos, the modern state of the coastal part of the Ukrainian shelf of the Black Sea may be characterized as mesotrophic-eutrophic.

Variability of elemental concentrations in cells of Ceratium hirundinella and Anabaena sp. measured by SEM XRMA were studied in relation to the conditions of the analyses. A point mode of analyses proved to be very variable due to the high heterogeneity of bioobjects, while results obtained by a medium-size reduced raster gave the best estimate of the concentrations in question. Larger sizes of reduced raster led to an underestimation of the measured intracellular concentrations probably due to a relatively high share of a cell wall and picking up void space, while results gained with smaller sizes of a reduced raster were subject to a high variability characteristic of a point mode analysis. Application of a medium-sized reduced raster could be recommended for measurements of intracellular elemental concentrations of freshwater phytoplankton species.

Variability of composition, pigment content (chlorophyll a, carotenoids, phycobiliproteins) and biomass accumulation have been studied in two strains of Nostoc punctiforme (Kütz.) Hariot (strain 38 and 39) and N. muscorum Ag. (strain 81) under conditions of different types of carbon nutrition. Infraspecific and interspecific variability of chromatic characteristics is found under heterotrophic (in light and darkness) conditions of Cyanophyta cultivation. Under the test conditions interspecific variability of pigments essentially prevailed over the infraspecific. All studied species of the genus Nostoc Vauch. differ in degree of photo- and heterotrophy. It has been established that variations in carbon nutrition conditions result both in destructive and in adaptive changes in the pigment content in the representatives of this genus. Physiological adaptation of the pigment apparatus of Cyanophyta on the photoheterotrophic type of nutrition with diurone is aimed at compensatory strengthening of the photosystem II activity, which is confirmed by intensification of synthesis in phycobilin pigments.

Research on cyanobacteria of prehistoric caves of Nahal Me'arot Nature Reserve was continued in Jamal Cave. Cyanoprocaryotes dominated in nine of 12 studied sites; two sites were occupied mostly by chlorococcal algae; diatoms appeared as single cells. In total, 29 species of 19 genera were revealed by direct microscopic observation and in cultures. Gloeocapsa Kütz. (4 species) and Gloeothece Nag. (3) were the richest in species. The majority of cyanoprocaryotes found in the cave are aerophytic, atmophytic, and terrestrial forms. The most common species were Gloeothece confluens and Chroococcidiopsis kashaii. Pseudophormidium edaphicum, Anabaena sp. ster., Cylindrospermum licheniforme, Scytonema julianum, S. javanicum, Tolypothrix tenuis f. terrestris, Nostoc linckia, and N. punctiforme grew luxuriantly in the cultures. Among species found in Jamal Cave, 17 were known previously from other caves, rocks, and soils of Mount Carmel National Park. Synechocystis pevalekii, Chroococcopsis fluviatilis, Porphyrosiphon luteus, Scytonema javanicum, Tolypothrix tenuis f. terrestris, and Calothrix pulvinata are the first records for Israel.

A variant of the analysis of results of experiments on detection of the damaging effect of toxicants on cultures of green microalgae is presented. It has been shown that such parameters as cell number, effectiveness of photosynthesis and average production respond differently to joint and separate action of small concentrations of phenol and catechol. The study of the summary index of the condition of an experimental biological system allows solution of the problem of additivity of the effect of toxicants irrespective of a mode of quantitative expression of their efficiency in relation to any parameter.

Dependence of the lipid composition of the blue-green alga Spirulina platensis (Nordst.) Geitl. on the mode of energy existence of cultures was studied. It has been shown that under conditions providing the possibility of alga's transfer to photoheterotrophy, the culture growth rate essentially increased, which was accompanied by some inhibition of the lipid accumulation process. It has been found that the content of monogalactosyldiacylglycerol (MGDG) was twice as low, that of sulphoquinovosyldiacylglycerol (SQDG) was thrice as low, while the content of phosphatidyl-glycerol (PG) was more than 1.7 times as high as in the control. Under conditions favorable for photoheterotrophy, the values of DGDG (digalactosyldiacylglycerol) ratios have increased. The revealed modifications in the composition of polar lipids evidence for a structural reorganization of the membrane apparatus in S. platensis due to changes in carbon nutrition conditions. Such structural reconstructions may provide some correction of the lipid matrix flowability and the sufficient stabilization level of proteins in electron-transport chains, pigments, and enzymes.

Selection of the most productive forms of Chlorella vulgaris Beijer. for mass cultivation under given climatic conditions was carried out by three methods: based on the parameters of synchronous cultures, in terms of the growth curves of algae in cumulative regime, and by autoselection. Cultivation was performed under stable laboratory conditions of growth typical for the Berlin region, as well as under natural outdoors conditions. Four strains from different collections were used: A-34, 211-11-s, C-1, and C-11. Cultures C-1 and A-34 were characterized by almost equal growth rates; the growth rates of these cultures were higher than those of cultures C-11, and 211-11-s. The cell cycle and light stage of the development of cells belonging to C-1 under given conditions were shorter. This evidence may be considered as a contributory factor for obtaining synchronization in the course of mass cultivation. Besides, it was found that C-1 in cultivating out of doors proved to be more tolerant to unfavorable factors of environment as compared to other cultures. The culture C-1 was isolated during the process of autoselection both under laboratory and natural conditions. Autoselection appears to be a simple and reliable method of selection of the most productive forms under given conditions of cultivation. However, this method can be used provided that chemical composition of the biomass produced is of minor importance.

The preservation of the basic morphological features of some filamentous Oscillatoriales (genus Phormidium) during four modes of artificial fossilization for mummification and formation of organic-walled microfossils was investigated. Posthumous variations of morphology of Oscillatoriales under various modes of fossilization - silification, phosphatization, carbonization, and formation of organic-walled microfossils (mummification) - are compared. The possibility of homologization of some morphological features of living Cyanophyta and microfossils with different modes of fossilization is demonstrated. Representation of main ecological groups of microorganisms and algae in fossil record is discussed.
