Irkutsk State University, Irkutsk, Russia

Abstract

The hypothesis of the probable presence of a congener forms in the Baikal Lake and Arctic Ocean sideswimmer faunas were critically considered and their insolvency has been recognized. The allocation of Pallasea and Gammaracanthus representatives at the north of Eurasia as well as their allocation on the probable way of the fauna migration between both basins were analyzed. The illustrated description of Gammaracanthus lacustris Sars from Khantayskoye lake is presented. The description of particular Baical variation of Arctic Ocean species G. loricatus (Sowinsky, 1915) is declared an obvious mistake.

North-Osetian Nature Reserve, Russia

Abstract

The Dagestan wild goat population included 2/3 of the isolated North-Caucasian part of the species range has been studied in 1990 and in 1995-1997. The species allocates at the upper halves of Avar Koisu and Andi Koisu river basins. The wild goat population inhabits the mountain forests on a steep and rocky slopes and shares this inhabitation with East-Caucasian tur. The total number of Dagestan wild goat is about of 1500. The wild goat rut lasts from the mid-December till the end of January and the birth-season lasts from the mid-June till the mid-July. The twins are common and fertility is noticeably higher than in an other conspecific populations and in the sympatric tur population. Dagestan wild goat population is in the close and constant neighborhood with a man and undergoes the strong anthropogenic pressure shaped the biology of this local population. Thus, the intense reproduction, preference of a closed forest stands and secrecy are the peculiar features of Dagestan wild goat population.

Forestry Institute of Russian Academy of Sciences, Moscow, Russia

Abstract

Data on the dynamic trends of a different type broad-leaved forests situated at the Serebryaniy Bor forestry (Moscow province) were obtained and future state of these forests has been predicted by the perennial stationary research work. The foliar plants will persist as an edificator species, but forest structure and composition will undergo the predictable transformations. The forest ecosystems included oak and asp trees will be involved in these transformations in the first instance. On the other hand, the cenosis role of birch trees will be stable and even enhanced.

Baikalian National Park and Hingan State Reserve, Russia

Abstract

The absolute number of population were estimated for the predatory birds in 1994 and in 1995 and for the rodents during the period of 1988-1995. The highest density of predatory birds nests were remarked in the 1994 (92 matches / 100 km2) and lowest one were remarked in the 1995 (30 matches / 100 km2). In the majority of predatory birds species the number dynamic and successful of nesting were influenced by the state of rodent populations of an open inhabitations. The nest density of predatory birds at the plain forestries of Hingan reserve is higher than in the most of another Russian regions.

Abstract

New data on the nesting of Iceland gull at Novaya Zemlya and description of the two specimens from Bezymannaya and Puhovaya Bays are presented. According with the data of 1993 and 1994 seasons this species allocates along the western coast of the archipelago at least from the Belush'ya Bay to Mityushova Island. The features of young and adult birds allow one to discriminate Iceland Gull and Glaucous Gull in the field conditions are described.

Kamchatka Institute of Natural Resources, Far East Branch of Russian Academy of Sciences, 6, Partyzanskaya str., Petropavlovsk-Kamchatskyi 683000, Russia

Abstract

The sexual dimorphism of the genus Icelus representatives were studied at Kamchatka coastal zone. The sexual dimorphism of an exterior features (fin length, male anal papilla) and body length (the body length is smaller in Icelus male than in female) has been shown. So, the dimorphic features of genus Icelus coincide with the dimorphic features of another Cottidae genera. The ratio between the male and female number is equal or the male number higher than female one in the groups of smallest specimens. The percentage of female increases with an increasing of the group mean body length and closes to 100 % in the groups of largest specimens.

Abstract

The article deals with the morphology, anatomy and distribution of protocorms and seedlings in the natural population of boreal orchid Dactylorhiza elodes (D. maculata complex) from the taiga surrounded Moscow State University White Sea Biological Station. The influence of abiotic factors on seedlings and duration of seedlings development are discussed. It was shown that different strategy of seedlings development may be realized under the different conditions.

Abstract

The bark anatomy of Forsythia species (F. giraldiana, F. intermedia f. spectabilis, F. ovata, F. suspensa, F. viridissima) has been studied. The phellogen in all these species originates from the epidermis in the first vegetation period. The phelloides form from cells of a current year or a last year and were not observed in the case of F. giraldiana. The stereom of one-year-old stalks consists of the protophloem fibres. The groups of sclereides spring up in the secondary phloem of a long-term branches. The sieve plates in these species with the exception of F. giraldiana have a complex structure and consist of 2-7 sieve fields. The anatomical characters revealed in this study and especially the periderm structure are of great importance for the diagnostic and may be used to clarify a position of the genus Forsythia in the family Oleaceae.

Abstract

New records of halophytic plant species, Eleocharis parvula , in Eastern Europe are presented. The species is reported for the first time from the shores of White Sea (two records in Arkhandelsk region and two records in Karelia). E. parvula is presumably restricted to desalinated areas near the river mouths at the White Sea shores. Though the species is frequent in suitable conditions, fruiting and flowering individuals are not found at the White Sea shores. The presence of E. parvula at the shores of Caspian Sea is confirmed by new record. An old, but neglected specimen of E. parvula from present-day St.-Petersburg is also reported. Ecology of E. parvula and the origin of White Sea populations of the species are discussed.

Abstract

The foundations of vascular plants flora's long-term monitoring were laid down by V.P.Rozhdestvensky and V.N.Voroshilov in 1924-1933. They detected 575 species of 313 genera and 81 families. The first control investigation of the territory (approx. 40 km2 was carried out in 1977-1986; 547 species of 282 genera and 76 families were registered then (V.B.Kuvaev et al., 1992). The second control investigation in 1996-1997 revealed 118 new species while 38 species vanished, so that total species diversity increased by 80, comprising 627 species of 81 families. The first investigation's data is in the discord with the facts obtained during the second one. Explanation of the results is given.

Abstract

The synantropic vegetation consists of the communities of Plantaginetea majoris, Molinio- Arrhenateretea, Chenopodietea, Agropyretea repentis and Bidentetea tripartiti classes. The new class Artemisietea rubripes has been preliminarily descriminated. The monsoon climate eliminates the conditions required for the development of urbanophilic kserothermic communities of orders Sisymbrietalia officinalis and Onopordetaia acanthii which composed the most part of synantropic communities diversity in the urbanized Europe regions.
