The need for an inventory and classification of special cases of diversity as one of the manifestations of variability is emphasized. The meaning of the term "biodiversity" is under debate. Taxa of biodiversity are termed "various", and the future science devoted to the investigation of diversity is called "variology" ("biovariology", concerning biological objects). Infraspecific and species diversity, as well as diversity of communities and the groups of species represent the main types of biodiversity. Main principles of the classification of infraspecific and species diversity are discussed. Modern methodological approaches to the study of species diversity of algae are elucidated. Strategies algae diversity to conserve are elaborated.

The effect of different wave length light on the process of transformation of zoospores to vegetative cells in the representatives of three phyletic lines of green coccoid algae (Chlorophyceae s. str., Trebouxiophyceae, Bracteacoccus) was studied. Blue and green lights were morpholagically active for all strains, although sets of the most effective wave lengths were different for each species: for Parietochloris alveolaris Bold CALU-856 it was near 400 nm, and 525-550 nm; for Bracteacoccus minor (Chod.) Petrova CALU-825 it included wave length of 400, 480, 538, 550 nm. The most effective wave lengths for Spongiochloris typica Trainor et McLean CALU-854 were 400, 480, and 525 nm. Heightened sensibility to red light was found in S. typica (Chlorophyceae s. str.) which, probably, is connected with presence of phytochromes. Differences in the active spectra of morphogenesis are phyletically determined.

Adaptation of the photosynthetic apparatus of Evglena gracilis Klebs to increased concentrations of dissolved toxic compounds, contained in sewage from the Urtviken pulp and paper factory (Sweden), was studied. It was shown that E. gracilis photosynthesizes under both low and high concentrations of untreated sewage.

It has been found that the activity of one of the antioxidant enzymes, catalase of Ceramium rubrum (Huds.) Ag. and Enteromorpha intestinalis (L.) Link, can be used as bioassay in evaluating the ecological state of marine waters. The level of catalase activity corresponding to the normal functioning of algae was determined. It has been shown that the threshold of sensitivity to nitrate in catalase activity of algae accounts for 2 mmol/L; the threshold of sensitivity of catalase activity to nitrite is one order of magnitude less.

A taxonomic list of green flagellate algae found in continental water bodies of Israel during 1999-2000 is presented. It contains 17 species belonging to one class (Chiamydophyceae), two orders (Chlamydomonadales and Volvocales), five families (Chlamydomonadaceae, Haematococcaceae, Phacotaceae, Spondylomoraceae, and Volvocaceae) and 9 genera. One genus (Pyrobotrys Arnoldi) is recorded for the first time in Israel. Fourteen species are new for Israeli flora, of which six are rare species, and one, Pyrobotrys maxima Massjuk et Lilits. sp. nov. is new species for science. Latin diagnosis and original drawings of the newly described species are presented, as well as drawings and descriptions of local populations of rare taxa, and the discussion of their deviation from the original diagnoses. Peculiarities of taxonomic composition of green flagellate algae of Israel are discussed, as possibilities for future studies.

Hydrophobia chromatography was used for the first time to purify phycobiliproteins. A method of phycocyanin production from the blue-green alga Spirulina platensis (Nordst.) Geitl. is proposed. The method includes isoelectric precipitation of proteins at pH Ј 4, production of the phycocyanin fraction I from the supernatant liquid, of the fraction II - from the sediment after its water-washing at pH < 4, and also subsequent purification by hydrophobic chromatography.

A closed equilibrated life support system has been developed. On the basis of a continuous microalgal culture as primary producer, an invertebrate level with Daphnia grazers as the primary predator, a vertebrate level with swordtail fish as a secondary predator and a natural degrader population were combined to close the trophic chain. It was demonstrated that a closed aquatic system, volume below 30 L, supplied with light energy only can produce sufficient food to support the survival of 10 g of vertebrates. Model project of bioenergetically and ecologically balanced agriculhiral production plant based on the principle of a synergistic production is described. Depending on proper function of design, the self-balancing ability of closed systems containing microalgae as a primary producer represent a means for tracing the material cycle within aquatic microecosystems.

The antifeedant and insecticidal properties of the two-species intensive culture of the marine microalgae, Platymonas viridis Rouch. and Nephrochloris salina Carter, were tested at the larval phases of the development of Leptinotarsa decemlineata Say and Hyphantria cunea Drury. The experiments were carried out using the native culture, its supernatant and pellet, the cultures differing in the content of nitrogen and phosphorus, and cultures exposed to thermal shock (freezing-thawing), as well as ethanol extracts of the pellet neutralized by calcium carbonate etc. It has been found that the trophic function of insects was distinctly inhibited during three-four days after the onset of the experiment. It has been also shown that the microalgae (native culture and its derivatives) demonstrate toxic activity, in this case, H. cunea was subjected to the inhibitory effect to a greater extent. The role of the factors adversely affecting the biological activity of intensive culture of microalgae is discussed.

Three small new species of the genus Thalassiosira Cl. (T. yunnaniana Khursevich & Kocioiek, T. bradburyi Khwsevieh & Kocioiek and T. iraidae Khursevich & Kocioiek) studied in light and scanning electron microscope are described from the Miocene freshwater deposits in Yunnan Province, China. All studied species have internal flat cribra covering individual loculate areolae on the valve surface. Moreover, an expanded diagnosis of T. kilarskii Kaczmarska known from the Miocene diatomites of western USA is also presented. Unlike the Chinese species, T. kilarskii has areolae with internal radial zigzag paths of continuous cribra. Also, the presence of valve face faltoportulae is reported in this species, a characteristic described as lacking in the original description.
