ECOLOGY-MORPHOPHYSIOLOGY CHARACTERISTICS OF THE INTERNAL-POPULATION GROUPS OF HOUSE MOUSE IN URBANOCENOSES
J.A. Kulikova, N.V. Sorokina, S.N. Gashev
Summary
Researching two groups of Mus musculus in the city of Tyumen: 1) they inhabit man made buildings; 2) resettle during the warm season on the street. It is shown that animals from these groups differ in complex of the ecological and morphophysiological symptoms. And also shown difference in the middle class, variments and allocations. To make a conclusion about the more stressed middle inhabitants for Mus musculus in man made buildings and about forced character of synantropy this species under conditions in Tyumen.
SINGING INVOLVEMENT, LEVEL OF SINGING ACTIVITY AND ACTIVITY RHYTHMS IN MULTISPECIES COMMUNITIES OF BREEDING PASSERINE BIRDS (PASSERIFORMES, FRINGILLIDAE, SYLVIlDAE)
V. V. Korbut
Summary
Quantitative study of bird involvement into singing was studied as a consequence of singing activity rhythms in Chaffinch, (Fringilla coelebs), Chiffchaff (Phylloscopus collybitus). Willow (Ph. trochilus) and Wood (Ph. sibilatrix) warblers. It was found that recorded singing activity is related to bird numbers, and various singing activity rhythms (seasonal, circadian and endogenous) can be traced with difficulty because of big variation. Support of both communicative relations and breeding community structure in Passerine birds with help of variability in level of singing activity and activity rhythms is discussed.
SOME SPECIALITIES OF WINTER ECOLOGY OF OCHOTONA PUSILLA IN THE NATURE PROTECTED RESERVE "ORENBURGSKIY"
A.A. Nikol'skii, E.E. Roschina, O. V. Soroka
Sommary
From January 31 to February 9 of 2000 the of Ochotona pusilla settlements were held in the nature protected reserve "Orenburgskiy" (Belayevskiy region of Orenburg area, the South Urals). The depth of the snow coverage and undersnow temperature was measured on the surface of snow and air. During the dark period of time if there was no strong wind, animals got out of snow on its surface to eat plants standing below the snow. Animals went out of their burrows' entrances on the amount of 130 m. in the Ochotonas' diets 8 species of plants were found. Scabiosa ochroleuca dominates. Ochotonas eat its collective fruits. On the second place but much rarely founded is Glycyrrhiza korshinskyi Grig. Other species are almost not founded. On the area of Ochotonas' winter activity average depth of the snow coverage is 38,5 + 2,3 cm. Average height of Scabiosa below the ground is 65,5 + 2,06 cm. Temperature of the ground under snow strongly depends on its' depth only from 0 to 50 cm. There is an opinion that the depth of snow coverage from 35 to 50 cm is enough for Ochotonas to use the thermal isolation quality of the snow, but at the same time such a depth doesn't prevent Ochotonas from taking food from the surface of snow.
ROLE OF LIGHT FACTOR IN SEASONAL DYNAMICS OF AN ALPINE SNOWBED COMMLWITY: EXPERIMENTAL APPROACH
A.A. Aksenova, V.G. Onipchenko
Summary
Shading experiment was carried out in an alpine snowbed community in the Northwestern Caucasus. Experimental plots were shaded (light penetration 5%) in 4 variants: control (without shading), shading for the whole summer, shading for the first and for the second half of the summer. The experiment lasted 3 years. Taraxacum stevenii, Catabrosella variegata, Carex oreophila, Corydalis conorhiza, Potentilla crantui, Hyalopoa pontica were the most shade tolerant species. Sibbaldia procumbens, Gnaphalium supinum, Agrostis vinealis, Minuartia aizoides were the least shade tolerant species. We have not found species, which were more tolerant to the first half summer shading than to the second half summer shading. Agrostis vinealis, Catabrosella variegafa ¨ Sibbaldia procumbens were more tolerant to shading for the second half of the summer than for the first half.
LIFE FORMS OF ROCKFOILS IN CONNECTION WITH THE GENUS SAXIFRAGA L. EVOLUTION (SAXIFRAGACEAE)
P.Yu. Zhmylev
Summary
The results of biomorphoiogical analysis of rockfoils in connection with the genus Saxifraga evolution are examined. It is supposed that the taxonomical evolution of this paleogenic genus was caused to a considerable degree by biomorphological adaptations. These adaptations have different display, but ander sharp changes in the conditions and mastering of new adaptive zones they have deviations character and this fact causes quantium fiatures of phylogenesis.
THE COMPARATIVE ANALYSIS OF FOOD STORAGES OF TWO OCHOTONA SPESIES - HYPERBOREA AND ALPINA IN NORTHWEST OF THE PUTORANA PLATEAU
V.Yu. Dubrovsckiy, Yu.A. Achtchekina, L.A. Chachuniants
Summary
The data about qualitative and quantitative (weight, %) structure of food storages of Ohotona hyperborea and Oh. alpina in three different habitats in northwest of the Putorana plateau are cited. Vegetation (abundance, %) on settlements of animals and around them is described. Food storages of both species in the similar habitats consist mainly of the same plants. A conclusion that there is no reason to separate ecological niches of both species basing on their fooding is drawn.

CONTRIBUTION ON THE FLORA OF MIDDLE RUSSIA
Summary
Data on 23 taxa, reported in II regions and republics of Middle Russia, are provided. Salsola laricina (as aborigenmal species), Gypsophila scorzonerifolia and Callistephus chinensis (as alien species) are shown for the first time for this region According to the authors' observations, the dynamics of distribution and ecological parameters of Lactuca saligna, Amaranthus powellii, Bidens frondosa are considered. Information about an aborigenal species Camphorosma monspeliaca growing at the territory of Middle Russia are confirmed. New species for Vladimir, Kaluga, Kursk, Moscow, Oryol, Saratov, Uliyanovsk regions and Republics of Tataria and Mordovia are reported. New theoretical projects regarding the inclusions of taxa, known only by sporadic findings, into floristic reference books, as well aas some aspects of their exclusion of regional floras.
