Dynamic Decomposition

Abstract On the base of experiments there were recorded the greatest mass losses of Sphagnum fuscum samples flat palsa mires in the first year of experiment, in the following years decay rate decreased significantly (from 24 % to 16 %). On middle taiga bogs there was observed decay rate increasing over the third year while on southern taiga bogs Sphagnum fuscum was decomposed almost evenly over three years. On ridges of ridge-hollow complex of middle taiga and southern taiga mass losses under destruction were greater than those in ryams. The most dynamic decomposition was recorded for forest-steppe ryam with decay mass losses over three years of 56% average.

Forest Reclamation

The effective of forest reclamation in oligotrophic and eutrophic swamps in the southern taiga and forest-steppe zones of Western Siberia are described. The state of the hydrological and gas regime of peat deposits is analyzed. It is concluded that forest reclamation 60 years ago on oligotrophic and eutrophic swamps has little effect on the hydrological and gas regime of the reclaimed territory at this moment. These regimes are approaching to their natural state, which indicates that the area is re-waterlogged in the absence of operation of the drainage system.

The data paper contains the authors’ materials on the diversity of macrophytes, macroscopic plants regardless of their taxonomic position, in rivers and streams of East European Russia and Western Siberia. These data, collected on 247 rivers and 32 streams in 13 administrative regions of the Russian Federation, were provided as an occurrence dataset presented in the form of GBIF-mediated data. The main portion of the data was obtained in water objects of the Vologda Region (5201 occurrences). In addition, occurrences from the Arkhangelsk Region (347 occurrences), Khanty-Mansi Autonomous Okrug (159), Yaroslavl Region (132), Novgorod Region (97), Kostroma Region (41), Republic of Karelia (31), Sverdlovsk Region (29), Komi Republic (28), Orenburg Region (26), Chelyabinsk Region (22), Voronezh Region (22) and Tyumen Region (18) were given. The studies were carried out mainly in the southern and middle taiga and, to a lesser extent, in the northern taiga and the forest-steppe. The analysed watercourses belong to five drainage basins: the Azov Sea, the Baltic Sea, the White Sea, the Caspian Sea and the Kara Sea. The dataset contains materials on the diversity of Plantae (6094 occurrences) and Chromista (59 occurrences). This paper, in a standardised form, summarises mostly unpublished materials on the biodiversity of lotic ecosystems. The paper summarises the data obtained in long-term studies of phytodiversity in a range of rivers and streams of East European Russia and, fragmentarily, Western Siberia. A total of 6153 occurrences were included in the dataset. According to the GBIF taxonomic backbone, the dataset comprises 292 taxa, including 280 lower-rank taxa (species, subspecies, varieties) and 12 taxa identified to the genus level. All the occurrences are published openly through the Global Biodiversity Information Facility (GBIF) for the first time. Most of the data were stored in field diaries and, thus, by adding the data in GBIF, we believe that other researchers could benefit from it.

The “standard model” consist on a) typical empirical distributions of CH 4 emission for main wetland landscapes in each natural zone of Western Siberia; b) durations of “period of CH 4-emission” (Tundra - 103 days, Forest-Tundra - 120 days, Northern Taiga - 138 days, Middle Taiga - 166 days, Southern Taiga - 172 days, Subtaiga - 193 days, and Forested steppe - 201 days); c) areas of different wetland types in each zone. For accounting future improvements we denominate this model by the code, for example: “Aa1” (first letter denominate the used period of CH 4-emission, second letter - the used areas of wetlands, and third - typical values of methane flux). New estimation of the regional methane emission from West Siberian wetlands (4.9 ± 2.3 Тg/year or 3.7 ± 1.7 ТgС/year) was calculated from “standard model” Aa1.

According to the data collected in the second half of summer for the period from 1954 to 2016 in the flat and mountainous parts of Western Siberia, the distribution and number of the narrow-headed vole in the zonal and provincial aspects were analyzed. Based on the cluster analysis of the matrix of similarity coefficients of abundance indicators obtained by averaging the initial data by years and groups of geobotanical maps units, the classification of habitats according to the favorable environmental conditions degree for the vole is made. The averaged samples are divided into five types of favorability: from optimal, where the abundance of the species is highest in the whole studied area, to extreme, where it is not encountered. In the South of the West Siberian plain narrow-headed vole prefers steppes, and in the subarctic tundras – communities of river valleys. In the Altai and Kuznetsk-Salair mountain regions it is most common in the subalpine light forests, tundras and tundra-steppe of the North-Western and SouthEastern Altai. On average, this vole prefers open habitats in Western Siberia. According to the classification and the structural graph, the dependence of the vole abundance on a number of factors and their inseparable combinations (enviromental and anthropogenic regimes) was revealed. The greatest connection with its distribution in the habitats of Western Siberia is traced for heat and water availability. On the plain, the number of this vole increases from the middle taiga, where it is found only once, to the subzone of the subarctic tundras in the North and to the forest-steppe and steppe zones in the South. In the mountains its more in the South-Eastern Altai, where a relatively high proportion of the most favorable for narrow-headed vole habitats.

The paper considers the modern network of protected natural areas in the Perm region. The study determines the current status of the network and the priorities of its geographical formation; investigates representation of six natural areas in the network; identifies the role of protected areas in biodiversity conservation. Based on the regional method, the degree of the protected areas natural environment degradation has been established. The network of protected areas consists of 361 objects of federal, regional and local significance. The total area reaches 10.7% of the Perm region‘s territory. The main component of the network is represented by 257 protected areas of regional importance. In the region, 6 natural areas have been identified: middle taiga, southern taiga, mixed coniferous-deciduous forests, Kungur forest-steppe, Western Urals, Northern Urals. Theinternational level of the protected areas network development has only been achieved in the Northern Urals. The share of protected areas in the middle taiga is higher than the average Russian level; for mixed coniferous-deciduous forests, it is close to the average Russian level. The least protected are southern taiga (4.8%) and forest-steppe ecosystems (3.8%). The most disastrous is conservation of the natural environment of the Kungur forest-steppe. There is a very small number of forest-steppe areas suitable for creating full-fledged protected areas. 89 rare species of biota inhabit the protected areas. All mammals, reptiles, amphibians, fish and invertebrates that are rare for the Perm region are covered with complete protection. Outside the network of protected areas, there are habitats of 7 species of birds, 21 species of angiosperms, 1 species of the fern-like, lycopods and lichen. On this basis, it is possible to develop territorial protection measures. The average environmental degradation of regional protected areas in the Perm region as a whole is 1.45 points. The degradation of protected areas is increasing in the series: middle taiga – Northern Urals – southern taiga – Western Urals – mixed coniferous-deciduous forests – Kungur forest-steppe.

Purpose. The history of the study of the Neolithic site with flat-bottomed ceramics of the Trans-Urals and Western Siberia is considered. Until the end of the 20th Century, such complexes in the region were correlated with the Boborykino culture. The formation of ideas about the main components of this culture determined the essence of the first two stages of the study of culture (from 1961 to the first decade of the 20th Century). Results. At the first stage, in the publications of K. V. Salnikov and L. Ya. Krizhevskaya, the characteristic features of the newly identified culture are defined: flat-bottomed ceramics with original ornaments and the microlithic character of flint inventory; the chronological positions of the culture are determined by the Eneolithic – Early Bronze Age. At the second stage, in the publications of V. T. Kovaleva and her colleagues, the Boborykino culture is assigned to the second stage of the development of ceramic ornamental traditions of the Neolithic Trans-Urals. The culture dates from the third quarter of the 6th – the first quarter of the 4th millennium BC. Initially, the autochthonous line of development of this culture from the early Neolithic Koshkino culture was substantiated. However later the alien character of this culture as a result of migration in the Trans-Urals of the early agricultural population of the Near East and the Caucasus began to be declared. At the third stage, by researching new archaeological sites in the Baraba forest-steppe and Middle Ob region, the age of archaeological sites with flat-bottomed ceramics was raised to the 7th – 6th millennium BC; the difference between local ceramics and Boborykino complexes was shown. The comprehension of sites with flat-bottomed ceramics of the period 7th – 6th millennium BC began as a new independent cultural-chronological phenomenon in the Neolithic of the Trans-Urals and Western Siberia. Conclusion. A version of the autochthonous origin of the Baraba culture is expressed. However, migration theories of the appearance of such archaeological sites in the north of Eurasia in their variations can also be discussed.

A new cultivar of smooth bromegrass (Bromopsis inermis Leyss) Flagman was developed by methods of mass selection and polycross. Breeding and wild forms of various ecological and geographical origins are used as an initial material. The authors of the cultivar: Kazarinova I.N., Polyudina R.I., Straub A.A., Gomasco S.K. Studies were conducted on the Central experimental base of the Siberian research Institute of fodder crops of the Siberian Federal Scientific Centre of Agro-BioTechnologies of the Russian Academy of Sciences, located in the forest-steppe zone of Western Siberia (Novosibirsk region, Novosibirsk district, Krasnoobsk). The cultivar is mid-ripening: the period from the beginning of spring aftergrowing to mowing ripeness is 63-75 days and to full maturing of seeds is 95-111 days. The yield of dry matter is 8.3 t/ha, which exceeds the standard by 8%, seed yield - 0.62 t/ha, higher than the standard by 28%. The dry matter yield of the cultivar Flagman for the fourth year of use exceeded the standard by 23% and reached to 11.4 t/ha. The 1000 seeds weight is 3.0-3.4 g. The plant height is 90-140 cm. Tilling capacity is up to 40 stems per tuft. Foliage varies from 32 to 50% depending on the age of the grass and environment conditions. The resistance of the cultivar to brown rust and helminthosporiosis is higher than of the standard. The copyright certificate No. 71916 and patent No. 9653 were received.
