Abstract
The condition of Southern Ural ungulate was determined by analyzing of fat concentration in shinbone marrow. In 64 % of cases fat concentration in marrow of wolf preys (84 samples were analyzed) exceeded than 50%. Thus, selectivity of ungulate elimination by predation is week.

Biogeography Department, Faculty of Geography, Moscow State University, 119899 Moscow, Russia
Abstract
The birds of western coast of Southern Island and birds of some islands in Muller's bay were studied during summer season of 1995. The number of barnacle goose and common eider nesting populations of Muller's bay were estimated as 10-12 and 8 thousand pairs. Data on the distribution and nesting ecology of barnacle goose, bean goose, common eider and some other species were obtained. An adaptive value of unusual (platform) nest type of the barnacle goose and common eider in island populations has been discussed. The Muller's bay species structure and bird's number in seashore colonies are presented.
D.N.Nankinov. The Phalarope (Phalaropus, Charadriiformes, Aves) migration over Bulgaria // Bull. Mosc. Soc. Natur. Biological Series. 1999. V. 104, part 3. P.18-21.
Institute of Zoology, Bulgarian Academy of Sciences, Sofia, Bulgaria
Abstract
All three Phalarope species of the world fauna are known from Bulgaria. Wilson's Phalarope (P. tricolor) is a typical rare unperiodical migrant observed only once (August 25th and 26th, 1992) at the Pomorie Lake. The Gray Phalarope (P. fulicarius) is also very rare species. There is only one proven observation (December 17th, 1965, Shabla Lake) and one doubtful observation. The Red-necked Phalarope (P. lobatus) is most numerous species. 436 Red-necked Phalarope specimens were recorded from 1882 to 1996. Bulgaria is on the way between the breeding and wintering ranges of Red-necked Phalarope Scandinavian population. 89,2% of individuals pass over Bulgaria from July 6th to October 22nd and only 10,8% of ones in spring between March 22nd and May 29th. The main staging state for Phalaropes in Bulgaria is the Atanassovsko Lake where 53% of recorded individuals stop and feed. Next in importance are Pomorie lake (39,9%) and Shablenska Tuzla (4,8%). The Law of Nature Protection protects Red-necked Phalarope, Grey Phalarope and their major habitats in Bulgaria. Since 1984 international importance of Atanassovsko Lake and Durankulak Lake was officially recognized under the Ramsar Convention.

Abstract
Changes in morphological characters such as morph number or grope number in a population indicate the level of antropogenic pressure from stage III (IV) of recreation. The individual specific morph number was higher in P. oblongopunctatus male than in female. The ratio kept constant during both seasons of our investigation and did not correlate with recreation pressure. The level of morphometrical characters variability remained constant during the season. We have not obtained significant differences between the areas with different recreation pressure in the set of body morphometical characters (body length, pronotum length, limits of pronotum width, elytron length) and in the number of fossa in the central and marginal elytron zone.

Higher Plants Department, Biological Faculty, Moscow State University, 119899 Moscow, Russia
Abstract
The generalized information on morphology, anatomy and organogenesis of roots and root systems has been given for Ranunculaceae with different living forms, longevity, developmental rhythms and ecology. We have revealed the homo- and heterorisois types of root system formation and the main tendency of theirs development in onto- and phylogenesis. Analyzing the fine structure of water crowfoot roots we have concluded they took an active part in the plant mineral nutrition. The latent and evident root particulation accompanied by abnormal secondary thickening is an important adaptive feature of high mountainous species. We have clarified the nature of "radical tubers". The term "gemmo- rhizous tuber" has been introduced. The tendency of rooting zone shifting from maternal shoot axis to the axile or terminal bud has been indicated.

Abstract
Relationship between the area and isolation degree of high mountain and incompleteness degree of subalpine meadow phytocoenoses has been analyzed. We have revealed that phytocoenoses of 0,01-2,80 squared km area of the high mountain have lost about 26-40% of species diversity since their isolation due to the "Island effect".

Abstract
Investigation of seasonal dynamic of 8 communities in mountain-forest, subgoltsy and alpine- tundra zones of Northern and Middle Basegi mountains was carried out during 3 years (from 1992 to 1994). The altitude increasing from 504 to 920 m.a.s.l. accompanied by the increasing of spring duration (from 45 to 56-59 days), decreasing of summer duration (from 62 to 41-33 days) and increasing of autumn duration (from 62 to 41-33 days). The shortest-term budding, flowering and fruiting were observed for alpin-tundra species and the longest-term ones were recorded for meadows species. We have distinguished 5 phenorhytmical groups among the studying species according the flowering date. Early summer flowering species was shown to be predominant in the communities.

Abstract
The hydrophilous flora of the islands includes 87 species. The water-paludal plants (N=65, 74,4% of investigated species) is predominant group. The group of hidrophyte plants (N=9, 10,3% of investigated species) includes hydatophyte species (N=8) and pleustophyte species (N=1). The group of halophyte plants includes 13 species (14,9% of investigated species). Halophyte plants are most wide spread in the studied region. We have revealed that their range limits coincided with arctic tundra boundaries and some species penetrated the polar deserts. Boreal and arctoboreal hydatophytes and hydro-hydatophytes are disposed in hypoarctic and southern arctic tundra i.e. only at south of the region. Halophytes have a more vast range. Water-paludal plants predominate mostly in polar deserts. We have concluded that the hygrophylous species and ecological group diversity increased at the southern part of investigated region (in hypoarctic and southern arctic tundra) where hygrophylous plants formed vegetation zones.

Abstract
Results of floristic investigation carried out in Astrakhan and Volgograd provinces have been presented. Caulinia graminea and Scirpus juncoides were first recorded in Russian flora. For the first time we have collected Monochoria korsakowii in Lower Volga region, Echinichloa caudata and Heliotropium suaveolens in Volgograd province and Lathyrus hirsutus in Astrakhan province. New collection sites of some other rare species have been presented.
