SOME GENERAL NOTES ON THE AVIAN HINDLIMB BIOMECHANICS

A.V. Zinoviev, F.J. Dzerzhinsky

Summary

Since the hind limbs carry out mechanical functions, their functional morphology is biomechanics. To interpret the morphofimctional peculiarities of the avian hindlimbs the biomechanical model (Gallus gallus bankiva was taken as an object) has been built using statics in graphic interpretation. The analysis of the three poses of the contact stage (very beginning, middle, very end) revealed the great sensitivity of the chosen graphic method to the geometrical traits of studied system. It has been shown that the vertical component of the femoral retractor's force acquired the ability to counteract the force of gravity tending to adduct the leg. Supination (outward rotation) of the femur as a result of collateral action of the mentioned muscles is neutralized partially by antitrochanter but mainly by mm. iliotrochanterici.

FAUNA AND BIOTOPICAL DISTRIBUTION OF SMALL MAMMALS (Rodentia, Insectivora, Lagomorpha) IN NORTHWEST OF THE PUTORANA PLATEAU

V. Yu. Dubrovskiy, L.M. Kanevskiy, 1. G. Pokrovskiy

Summary

In July-August 1998 some data about structure of population of rodents and insectivores has been collected for the first time on the eastern sides of the Lama lake (the northwest of the Putorana plateau). We succeeded in detecting of the next species of rodents: Clethreonomus rbtilbs, C. rufacfnus, Vicrotus Middendorfi, lagomorphs: Ochotona hyperborea, 0. alpina, and insectivores: Sorex caecutiens, S. roboratus, S. tundrensis, S. minutissimus. Abundunce of species and their biotopical distribution were determined. Similaruty and difference between faunas of region of researches and of adjoined terntines are considered.

THE GENERAL CHARACTERISTIC OF TAIMYR RESERVE VASCULAR FLORA ON THE BASIS OF LOCAL FLORAS ANALYSIS

E.B.Pospelova

Summary

The results of taxonomical and geographical analysis of 14 local vascular floras (LF) of State Biosphere Reserve <Taimyrsky>, characterizing arctic, typical, south and alpine tundra, are reported. Their species diversity increases naturally towards south-west, from 100-150 species in arctic to 260 - in south tundra; the mountain-foothills polylandscape LF of the south Byrranga macroslope are most rich (300-320 species). The structure of the first 5 families is invariable on the full length of relative submeridional transect - Poaceae, Brassicaceae, Asteraceae, Cyperaceae, Caryophyllaceae, except of arctic tundra LF, where a role of Saxifragaceae is more, but Asteraceae is less. The leading genera are Draba, Carex, Saxifraga, the last is more active in arctic and mountains LF. The role of families Rosaceae, Papaveraceae, Fabaceae and genera Papaver, Potentilla, Poa increases in the mountain LF. In the geographical structure species of cryophyte group prevaile (50-90%), their percent decreases toward south, on the contrary, a percent of hypoarctic and boreal species increases; it is great in the mountain-foothills LF too. The circumpolar species prevaile in all LF(40-60%), their percent is increased from north to south. A percent of East-Siberian continental species is the most in the mountain-foothills LF (17-19%); percent of Eurasian - in the LF of typical and south tundra plain. The optimal dendrit is built on the basis of connection-coefficient matrix; on this scheme the following LF-groups are distinguished - LF of arctic tundra, mountains, mountains-foothills, typical tundra, south tundra.

COMPETITION IN ALPINE PLANT COMMUNITIES: RESULTS OF IO-YEAR TRANSPLANTATION EXPERIMENT. SHOOT NUMBER DYNAMICS

E. V. Volkova, V. G. Onipchenko

Summary

Reciprocal transplantation among four plant communities were carried out in alpine zone of the northwestern Caucasus. As initially expected, many species from the two more productive habitats (alpine grasslands and meadows) performed poorly in the less productive environments of alpine tundra and snow beds, while species from the latter two habitats performed on average better in the more productive environments, than in their native habitats. However, a few species from each community demonstrated clear preference for their native habitats, regardless of the productivity. Also, there were a few species in each community that grew better in any other community, but not in the community of origin.

SOIL-VEGETATION COVER OF VANKOR OIL FIELD TERRITORY (THE NORTH OF WEST SIBERIA) AND IT'S TECHNOGENIC TRANSFORMATION

D.A. Shakhin, V.M. Telesnina

Summary

The main features of natural as well as destructed landscapes were studied on Vankor oil field territory ( southern-west part of Gydan peninsula). Flora, vegetation , soils and their landscape distribution are considered. The character and scale of technogenic destruction, including chemical pollution, erosion and thermocarst are described. Also the zones of succession: 1) zone of absent soil and vegetation; 2) zone of intensive destruction of soil and vegetation; 3) zone of secondary meadows and swamps; 4) zone without essential destruction. The some attention was given to destruction of tundra territory as source of pasturages.

A REVISED CLASSIFICATION OF EUPHORBIA SECT. HOLOPHYLLUM (EUPHORBIACEAE)

K.S. Baikov

Summary

A revised classification of Euphorbia sect. Holophyllum is presented. 22 species, three subsections, and eight series are recognized within the section. Two series described by Ja. 1. Prokhanov are accepted as subsections. A new subsection and five new series are described.

MONOCARPIC SHOOTS AND BIOMORPHS OF TYPHA SPECIES IN CONNECTION WITH THEM SYSTEMATICS

Yu.E. Alexeev, E.V. Mavrodiev

Summary

Morphological features of monocarpic shoots and three allocated biomorphs Typha are discussed. The descriptions of monocarpic shoots are made pursuant to the <Formula of monocarpic shoot> (Alexeev, 1996). Systematic significance of the formulas ofmonocarpic shoots and biomorphs Typha is shown.

PLATS SPECIATION IN SUBARCTIC MOUNTAINS AND ARCTIC REGIONS

V.B. Kuvaev

Summary

The taxa-formation in Arctic regions and subarctic mountains by common scheme get; varietas, subspecies, microspecies, species a evolutionary-taxonomic series formed. Becouse of special conditions in Arctic regions and subarctic mountains here change interrelations of plants. Pantopic taxaformation predominate, by this primary taxa to derivative transform directly. New taxa settly from south to north and from lower belts to highlands on the whole.

VALIDATION OF SOME SUPRAGENERIC TAXA IN DICOTYLEDONS (ROSOPSIDA, SEU MAGNOLIOPSIDA)

A.B. Doweld

Summary

Three ordinal (Akaniales, Nandinales, and Trimeniales) and four family names (Canacomyricaceae, Huerteageae, Platycaryaceae, and Sinofranchetiaceae) that were not formerly validly published by various authors are formally validated. In addition, four names (Akaniales, Nandinales and Huerteaceae, Sinofranchetiaceae) not properly validated by A.B. Doweld are included.
