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 This paper, in a standardised form, summarises mostly unpublished materials on the biodiversity of lotic ecosystems.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 data on the species diversity of representatives of the genus Teilingia Bourrelly are summarized. from the water bodies of Western Siberia, their distribution by zones and subzones. To date, 4 species and intraspecific taxa from the order Desmidiales are known for the region. Representatives of this family are found mosaically throughout the entire territory of Western Siberia. The largest number of taxa (3) was found in the middle taiga, in the tundra – two species. No species were found in the Irtysh floodplain, forest tundra, northern taiga, forest-steppe and steppe zones. In watercourses, including the Ob and Irtysh, as well as in lakes of different types, 3 taxa were identified, respectively. One species was found in swamps and in temporary reservoirs.

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.

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.

The purpose of the research is establishing the composition, infection rates, species and group ratio of ectoparasites of the East European vole on the northern border of the range in Western Siberia (Middle Ob Region). Materials and methods. In 2015–2018, in order to capture the provider of ectoparasites, the East European vole, we used methods of trap lines, trap trenches, and fence-traps; we recorded 173 animals from which we collected 881 specimens of gamasid mites, ixodic ticks, lice and fleas. To assess the quantitative indicators of ectoparasites, the indices generally accepted in parasitology were used. Results and discussion. In 2014, it was established for the first time that there is a sibling species of the common vole, the East European vole in the Middle Ob Region (middle taiga of the forest zone of Western Siberia). In the city of Surgut and its neighborhood, this animal is confined to the most transformed biotopes. The ectoparasite complex of the East European vole includes 26 species of parasitic arthropods. By the number of species (13) and individuals, gamasid mites predominate, and the proportion of ixodic ticks, lice and fleas put together is almost 3 times lower. In a climate of the Middle Ob Region, the list of ectoparasites will no doubt grow as the range of habitats expands and the contacts of the East European vole with other small mammals increase, and its role in maintaining pathogen circulation of natural focal infectious diseases will increase.

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 presents the results of the study of the Sarov complex in the Roza Vetrov VII settlement, located in the forest-steppe Tobol River Region (Western Siberia). The Sarov stage of the Kulayka Culture terminates the Early Iron Age and dates to the 1st c. BC — 3rd c. AD. The dwelling represented by a hut-like superstructure used by fishermen during the spawning period of the warm season is described. Also characterised are the tools in-cluding pestle, grindstone, and a fragment of the casting form. The pottery complex reflects all specific features of the Sarov stage ware — the monotony of the ornamental composition, which consists of multiple repetition of rows of the combed stamp and waves, downswept rims. The characteristic of the sample is the complete absence of figured stamps in the ornamentation. The time of migration of the northern taiga population into the sub-taiga and forest-steppe zones of Western Siberia is based on the chronological position of the Sarov sites and specifics of the historical and cultural situation in the present region in the end of the Early Iron Age. The Sargatka Culture, which was spread in the territory of the forest-steppe Trans-Urals, existed until the end of the 2nd — early 3rd c. AD. The Sarov complex of the Ayga VIII settlement is attributed to the 3rd c. AD; the burials of the multicultural Kozlov burial ground, where the Sarov pottery has been found, are dated to the 3rd–6th c. AD. The spread of the Sarov population occurred from the Surgut area of the Ob River Region or the Lower Irtysh River Region along the main water arteries — the rivers of Irtysh, Tobol, Tura, Iset — from the 3rd c. AD. The Sarov materials of the Roza Vetrov VII settlement could be dated to the same time. The Sarov population took part in the genesis of the early medieval cultures of the forest-steppe and the sub-taiga Trans-Urals. Bakal Culture inherited from the bear-ers of the Sargatka Culture the pottery ornamentation technique, while from the population of the Sarov and Kar-ym Cultures — the shape of vessels with a whisk and cornice sloping inside. The influence of the northern taiga population can also explain the spread of fortifications with bastions in Tobolo-Ishim Region.

Birch forests with the dominant Betula pendula form on the territory of the Western-Siberian Plain asubtaiga zone, which is an analogue of the zone of broadleaf forests of European Russia. In addition, birch is an importantcomponent of the ring forest steppe of Western Siberia. As a zonal type of vegetation, birch forests include special species.Their occurrences are shown on the example of birch forests of Aromashevsky district in Tyumen region. The mechanismof their phytocenogenesis is proposed.
