The currently available data on the role of blue-green algae in nature (accumulation of organic matter, participation in the biogeochemical cycle, water quality assessment, their influence on living organisms, etc.) are briefly summarized. The importance of a knowledge of the regularities of the distribution and functioning of Cyanophyta in natural habitats for the elaboration of the theoretical foundations of their monitoring, conservation, and economic utilization, including the use of Cyanophyta as on object of new biotechnologies, is underlined.

Generalized literature and original data on diversity of algae (including cyanoprocaryotes) of the continental part of Israel are analysed. Peculiarities of the Israeli algoflora are characterized with reference to its endemism. To date 289 genera and 1208 species (1309 infraspecific taxa) of algae are known in continental Israel. Bacillariophyta (402 species, 437 infr. taxa), Chlorophyta (335 species, 364 infr. taxa), and Cyanoprocaryota (327 species, 349 nfr. taxa) are the most diverse taxonomic groups in the Israeli flora of algae.

Recent results of the Bacillariophyta use in biomonitoring of lotic systems have been generalized. Their high indicatory qualities relative to different parameters of water environment and advantages over other water organisms in biomonitoring of water ecosystems are shown. The classification of Bacillariophyta communities as a theoretical and practical base for biomonitoring of ecosystems is considered for the first time. The ways of solving certain problems arising in classification of microscopic plant communities are discussed on the example of Bacillariophyta communities.

Chlorophyll a concentration, ash-free dry weight (AFDW) and accumulation rate of organic matter (net productivity) were determined for periphyton assemblages developed on artificial substrate (glass slide). Periphyton samples were obtained by exposing glass slides on periphyton samplers, which were placed at 12 sampling stations with different levels of pollution around the Pinang River basin. Biomass and chlorophyll a concentration were highly variable, and the highest values were recorded at relatively polluted stations, where biomass peaked at 10.48 mg Chl. a/m2 and 8.24 g/m2 AFDW. Maximum biomass at clean sites was 4.1 mg Chl. a/m2 and 2.45 g/m2 AFDW, with maximum net production 85.71 mg AFDW/day. The accumulation of chlorophyll a and AFDW was characteristically higher during the drier months and relatively lower during the wet season at all sampling stations. AFDW positively correlated with chlorophyll a and net productivity.

The rare species Carteria abiscoensis Skuja previously known only from Swedish Lapland was found in the water bodies of Ukraine. Study of morphological diversity of three populations of this species (two from the Carpathian Biosphere Reserve and one from the Goloseevo pond in Kiev) revealed at times continual and sometimes discrete variability of some morphological characters (shape, dimensions and location of stigma and pyrenoid, depth and width of the anterior excision of chloroptast, thickness of the cell wall, dimensions of cells). This variability shows up both on the intra- and interpopulational levels. Taxonomic interpretation of variability revealed is proposed: two new for science infraspecies taxa, C. abiscoensis var. kyivensis Massjuk et Lilits. var. nov. and C. abiscoensis var. abiscoensis f. carpatica Massjuk et Lilits. f nov. are described. The descriptions, Latin diagnoses and original drawings are given.

The planktonic algae in Gölbasi Lake and their seasonal variations were investigated between April 1997 and March 1998. A total of 69 taxa have been determined. The phytoplankton comprised the members of the Bacillariophyta, Chlorophyta, Cyanophyta, Dinophyta and Euglenophyta. Bacillariophyta was the most significant algal division of the phytoplankton in Gölbasi Lake. Cyclotella comta (Ehr.) Kütz., Cyclotetta meneghimana Kütz., Cyclotella ocellata Pant, and Synedra ulna (Nitzsch) Ehr. were the most conspicuous diatoms in terms of occurrence frequency and abundance of individuals in the phytoplankton.

A living model of actively ramifying stromatolites, being a build-up of two hundred alternate layers: dark (organic) and light (mineral), was first obtained under laboratory conditions. Its formation was realized by means of copying fossil build-up morphology of Pre-Cambrian columnar stromatolites from the super-group of tungussids (Baicalia Kryl., Parmites Raab.) by means of artificial regulation of algobacterial film growth on the surface of a layer of mineral sediments.

The general chemical and carbohydrate composition of storm fling biomass in hypergaline reservoirs of Sivash Lake were studied. It was determined that the biomass contains compounds characteristic to plant hydrobionts: proteins, lipids, carbohydrates, and microelements. The feature peculiar to biomass composition is the presence of iodine compounds in it in concentrations exceeding those in such powerful concentrators of iodine as phaeophytes. Significant amounts of carbohydrates represented mainly by freely hydrolyzing polysaccharides were detected. Results of the study of monosaccharide composition in freely hydrolyzing polysaccharides show that this polysaccharide differs significantly from those of macrophytic algae. This polysaccharide could be allocated to the microalgal polysaccharides. A preliminary assessment of the physical and chemical properties of the polysaccharide isolated from the biomass has shown that it can be used as a stabilizer for food, forage, and for technical purposes.

Bacteria, as a heterotrophic component, are a part of various algal-bacterial communities (associations) formed in natural environments. The species composition of the accompanying microflora is studied most completely in a number of algal species from the genera Chlorella Beijer., Stichococcus Nag., Scenedesmus Meyen, Dunaliella Teod. and Spirulina Turp. Some evidence on satellite bacteria of algae from the genera Bracteococcus Tereg, Pleuchloris Pasch., Microcoleus Desmaz. and others is also available in literature. The results of the analysis of the data both from literature and original, testify to the constant and definite species composition of bacteria accompanying algae in culture and natural habitats. The specifity of the species composition of bacteria is manifested at the generic level of the primary producer, though there may be differences depending on the algal strain. Along with the taxonomic position of algae, the ecological conditions of their habitats in nature or in cultures are also crucial factors of the species composition of the heterotrophic component of algal-bacterial communities. The heterotrophic component is mainly represented by constant satellite bacteria of algae, including the dominant and minor species, in the number from 4 to 12 and more. However, in its composition there are also rarely occuring, random and infecting microorganisms, including antagonists and parasitic forms. Natural changes in dominant species of satellite bacteria are observed during the algal growth and development.
