The fauna of the rivers of the north of Western Siberia that do not belong to the Ob’ River basin is of particular interest from the point of view of zoogeography and understanding of the processes of formation of the freshwater malacofauna. Starting in the taiga zone, these rivers flow north and cannot serve as a way of interzonal dispersal of species from lower latitudes. However, information about the fresh-water malacofauna of these river basins is poorly presented in the scientific literature, some of the published species findings are doubtful or erroneous. The gastropod mollusks of the family Valvatidae of the Taz river basin (Western Siberia) are considered. The basin is located closer to the Yenisei than to the Ob’ River basin. The study was based on original authors’ material represented by both qualitative and quantitative samples. It has been found that eight species of mollusks of the genus Valvata occurs in the water reservoirs and streams of the Taz basin, an annotated list of species is presented, and a brief zoogeographic characteristic is given. Three species (Valvata helicoidea, V. sorensis and V. korotnevi) are for the first time recorded from the basin, one of them (V. korotnevi) is for the first time recorded from the Western Siberia waterbodies.

Based on a study of samples made by the author, 70 species of freshwater bivalves belonging to 6 genera and 2 families are recorded for the Taz River basin (north of Western Siberia). An annotated list of bivalves of the Taz basin is provided, with data on species’ range, their findings in Western Siberia and within the studied area. Some information about bionomics and abundance of bivalves are given. 45 species are for the first time registered in this basin. Most studied molluscan communities are characterized by low species richness; the distribution of species by their occurrence was extremely uneven. 22 species are characterized as rare. The highest species richness of bivalves was found in river channels, rivers and brooks; the lowest - in temporary habitats. The core of the fauna is constituted by species with broadest range (cosmopolitan, trans Holarctic, trans Palearctic) as well as by taxa with European Siberian type of distribution. From the taxonomic point of view, the bivalve fauna of the Taz basin is relatively separated from the faunas of other river basins of Western Siberia and is more similar to the fauna of the Lower Yenisean zoogeographic province (sensu Starobogatov [1986]).

<p>The activities of ancient population strongly affected the development of landscapes and soils in Western Siberia during the late Holocene. It should be noted that studies devoted to the processes of natural and anthropogenic evolution within this vast territory are extremely irregular. Thus, the significant proportion of the materials on the dynamic of Siberian landscapes in the Holocene, related to the studies of various natural archives and archeological monuments, falls on the southern part of region. On the one hand, this situation is due to the relatively recent development of Western Siberia in relation to the development of hydrocarbon deposits, on the other hand, on the peculiarities of the relief and landscapes prevailing in the central and northern parts of the West Siberian Plain. A significant part of the territory under consideration is characterized by low, poorly dissected relief, which largely contributes to its bogging and widespread distribution of organogenic peat soils. It is not surprising that the deposits of lakes and peat bogs are the main natural archives that provide information on the dynamics of the natural environment within the central parts of Western Siberia and, first of all, the taiga zone, while the potential of mineral soils and sediments from this point of view is insignificant, compared to other regions. At the same time the boreal zone of Western Siberia is very large and includes regions with more complex geomorphological conditions.</p><p>To assess the possibility of using buried soils and colluvial layers in the middle taiga of Western Siberia for reconstruction of the Holocene landscape’s dynamics, we carried out research on two key sites with rather contrast relief and high frequency of archeological sites: in the middle Yugan River Basin and in the North of the Kondinskaya Lowland. Buried soils and colluvial sediments in a number of sections characterizing foots of the steep slopes on the border with peat bogs were selected as objects for our study. Based on the obtained radiocarbon dates it is possible to preliminarily identify several stages of the activation of erosional processes. For the north of the Kondinskaya lowland three remarkable phases of erosional activity were identified, while for the Yugan River Basin the number of phases was larger - 6. It is interesting to note that the obtained results make it possible to correlate these two regions. The presence of a larger number of recorded erosion-pyrogenic events for the Yugan River basin reflects a longer permanent human presence in the area under consideration, which is also consistent with archaeological data.</p><p>The study was funded by the Ministry of Science and Higher Education of the Russian Federation and was performed as a part of project FEWZ-2020-0007 “Fundamentals of the natural environment history of the south of Western Siberia and Turgay in the Cenozoic: sequence sedimentology, abiotic geological events and the evolution of the Paleobiosphere“.

The article continues the author's research on the toponymy of the North-East of the Sakha Republic, in particular the Kolyma river basin, in the aspect of the interaction of related and unrelated languages. The relevance of this work is defined in the description of local geographical terminology of Yukagir origin, as a valuable and important material in the further study of toponymy of the region. For the first time, the toponymy of the Kolyma river basin becomes the object of sampling and linguistic analysis of toponyms with local geographical terms of Yukagir origin in order to identify and analyze them linguistically. The research was carried out by comparative method, word formation, structural, lexical and semantic analysis. As a result of the research, phonetic and morphological features are revealed, the formation of local geographical terms and geographical names of Yukagir origin is outlined, and previously unrecorded semantic shifts and dialectisms are revealed. The most active in the formation of terms and toponyms is the geographical term iилil / eҕal 'coast‘, which is justified by the representation of the Yukagirs’ coast' home, housing

Waste Water Management

In Austria approximately 70% of the population is connected to sewerage and to biological waste water treatment plants. Whereas the urban areas are already provided with these facilities to a very high extent, effort is still needed in rural areas to meet the requirements of the Austrian legislation. The way, this task should be solved has provoked much controversy. It is mainly the question, whether centralised or decentralised sewage disposal systems are preferable from the ecological and economical point of view, that became a political issue during the last 5 years. The Institute for Water Quality and Waste Management was asked to elaborate a waste water management concept for the Lainsitz River Basin, a mainly rural area in the north of Austria discharging to the Elbe river. Both ecological and economical aspects should be considered. This paper presents the methodology that was applied and the criteria which were decisive for the selection of the final solution.

In any discussion of the historical development of what was later to be named Biostratigraphy it is often assumed that a modern basis for the subject had already been reached by the cumulative work in the subject up to 1815; culminating in that of William Smith (1769-1839) and Alexandre Brongniart (1770-1847). But to this time fossils had only been used to identify (and discriminate between) often repetitive lithological units or to establish a relationship between rock units in different areas. The practical demonstration that particular lithological units could be regularly subdivided with significant consequences, on the basis of their contained fossils was a later achievement over several generations. One of the first to free stratigraphical palaeontology from such a lithological control was the forgotten Englishman Louis Hunton (1814-1838). In this paper Hunton's origins from a successful alum making family in the north-east of Yorkshire in the north of England and his short life and scientific work are described for the first time. The family business of alum making from the highly fossiliferous local alum shales, which were extracted open-cast, directly introduced Hunton to stratigraphical palaeontology. He followed up this work by study in London, where his pioneering paper was read to the Geological Society of London in 1836. He died less than 2 years later but had helped lay a foundation for major biostratigraphic advances by his insistence that only fossils collected in situ should be used in such work and then that the species, of especially ammonites, in his Yorkshire strata had particularly limited and invariable relative positions within that lithological sequence. His work is also compared with that of his contemporary W.C. Williamson and the conclusion reached that Hunton, because of his emphasis in the merits of ammonites, deserves more to be remembered as a pioneer of Jurassic biostratigraphy.

We report upon eleven species of thecate hydroids collected during a recent scientific expedition to the North Patagonian Zone between southern Chiloé and Puyuguapi fjord/ Magdalena Island. One species belongs to the family Haleciidae Hincks, 1868, four to the family Sertulariidae Lamouroux, 1812, and six to the family Campanulariidae Hincks, 1868. Of them, Halecium cymiforme Allman, 1888 and Symplectoscyphus leloupi El Beshbeeshy, 1991 are redescribed based on new, fertile material. Sertularella allmani Hartlaub, 1901 is assigned to the synonymy of S. antarctica Hartlaub, 1901. Campanularia subantarctica Millard, 1971 is considered as a junior synonym of C. lennoxensis Jäderholm, 1903, and data on both the male and female gonothecae are provided. A variant of Clytia gigantea (Hincks, 1866) with smaller hydrothecae than usual is described. Sertularella sanmatiasensis El Beshbeeshy, 1991 is recorded from Chile for the first time. Although not belonging to the present collection, several notes on Kirchenpaueria curvata (Jäderholm, 1904) are provided.

Pia Haudrup Christensen: Children’s perception of time spent with the family This paper examines time spent with the family from children’s point of view. Since the 1960s notions of “quality time“ versus “quantity time“ have been employed to capture the everyday reality of working parents and their children. Some researchers have argued that parents should spend “more time“ together with their children and less time working, while others have suggested that it is important to examine how parents and children spend their time together. These discussions of what is “good“ for today’s children tend to neglect children’s perspectives. This paper draws on extensive ethnographic studies among 10-11 year old children about their understandings and use of time in an urban and a rural area of the North of England and in a district of Copenhagen, Denmark. The paper argues that the quality/quantity conundrum needs to be replaced by fuller and more representative accounts that include dimensions of family time that matter for children. The paper examines the six qualities of time that children value: “ordinary everyday family routines“, the notion of “hygge“ or coziness in Danish, “someone being there for you“, to “have one’s own time“, time for “peace and quiet“, and to be able “to plan own time“. It argues that children’s view of time spent with their families cannot be seen in isolation from the time they spend with friends, time at school and on their own. It concludes that children’s time needs to be situated in the everyday processes of balancing family, school and work life which both children and parents engage in.

The possibility of use of the previously developed calculation technique of the North Rivers flow hydraulic records for the Ob River, the largest river in Russia by basin area, flowing under severe conditions in West Siberia was examined. The calculation technique is based on the model of heat and moisture exchange of the geological substrate with the Earth’s atmosphere, the Soil-Water–Atmosphere–Plants (SWAP) model, in conjunction with information support based on global databases of geological-substrate parameters and information obtained from observational data collected by weather stations within the Ob River basin. Uncertainty of the Ob River flow was assessed. Additionally, the ability of the SWAP model to reproduce multiyear dynamics from average values of snow reserves in the Ob-Irtysh basin was examined.
