Aus Beobachtungsdaten der Satellitenmission GRACE (Gravity Recovery and Climate Experiment) können Variationen des Erdschwerefeldes auf großen räumlichen Skalen mit hoher Genauigkeit abgeleitet werden. Die Variationen auf zeitlichen Skalen von mehreren Tagen bis Wochen und räumlichen Skalen von wenigen hundert Kilometern sind insbesondere auf Änderungen der kontinentalen Wassermassen zurückzuführen. Die vorliegende Promotionsarbeit beschäftigt sich mit der Bestimmung hydrologischer Massenvariationen aus GRACE-Daten am Beispiel der vier größten sibirischen Flusseinzugsgebiete Ob, Jenissei, Lena und Kolyma. Darauf aufbauend sollen in Kombination mit atmosphärischen Daten der NCEP-Reanalyse Süßwassereinträge in den Arktischen Ozean abgeleitet werden. Die Süßwassereinträge beeinflussen nachhaltig den Salzgehalt und damit das ozeanographische Regime des Arktischen Ozeans, welcher wiederum einen Einfluss auf die globale thermohaline Zirkulation hat. Da die großen Strömungen des Weltozeans einen grundlegenden Faktor des globalen Klimageschehens darstellen, sind die Änderungen des Süßwassereintrages ein wichtiger Aspekt hinsichtlich prognostizierter Klimatrends. Der Abfluss kann an ausgewählten Messpunkten mit einer hohen zeitlichen Auflösung beobachtet werden. Die Datenreihen weisen jedoch immer wieder Lücken auf und die bodengebundenen Messungen sind oft schwierig und kostenintensiv. Messmethoden, die unabhängig vom Zugang ins Messgebiet sind, können einen großen Fortschritt bei der Beobachtung sich ändernder Massen und Süßwasserflüsse leisten und damit einen Beitrag für ein besseres Verständnis gekoppelter komplexer Prozesse der Arktis liefern. Da die Fehlerstruktur der GRACE-Daten komplex und bis heute nicht vollständig verstanden ist, erfolgt zunächst eine Untersuchung des GRACE-Fehlerhaushaltes. Zudem werden die Fehlereffekte aufgrund des begrenzten räumlichen Spektrums und damit einhergehender Leck-Effekte auf Ebene von Gebietsmittelwerten analysiert und Lösungsvorschläge diskutiert. Dabei sind folgende Aspekte von Bedeutung: Erweiterung der GRACE-Datenreihe um geeigente Terme ersten Grades und Abschätzung von Leck-Effekten, verursacht durch das begrenzte Spektrum der Kugelfunktionsentwicklung. Leck-Effekte aufgrund ozeanischer Signalanteile sind bzgl. der Einzugsgebiete sibirischer Flusssysteme klein (< 1%), wohingegen Leck-Effekte aufgrund kontinentaler Signalanteile je nach Gebietsgröße relative Fehler von 8-17% nach sich ziehen. Die größten Fehlereffekte resultieren jedoch aus den Koeffizienten hoher Grade. Die Filterung der GRACE-Daten ermöglicht die Glättung fehlerbehafterer Signalanteile. Neben den in der Literatur gängigen Filtern wurde im Rahmen der Arbeit ein Kombinationsfilter entwickelt, welches auf Basis von räumlichen Vorinformationen aus Hydrologiemodellen signifikante Signalstrukturen in den GRACE-Datenreihen detektiert. Somit muss lediglich ein Restsignal mittels Filterung gedämpft werden. Mit dem Kombinationsfilter können sowohl feinere Signalstrukturen als auch größere Signalamplituden auf Land erhalten werden. Im Vergleich zu reinen Filteranwendungen werden hier Gesamtsignalstärke, Amplitude und Phase des jährlichen Signals gut repräsentiert. Darauf aufbauend lassen sich, in Kombination mit atmosphärischen Daten, Abflüsse für die sibirischen Flusssysteme aus GRACE-Wasserspeichervariationen ableiten. Die Validierung der berechneten Abflüsse anhand beobachteter Abflüsse zeigt eine hohe Übereinstimmung von bis zu 83%. Eine Gegenüberstellung des berechneten Abflusses der Lena mit Wasserstandsmessungen im Mündungsbereich zeigt zudem einen Zusammenhang zwischen dem maximalen Abfluss im Frühjahr und einer Zunahme des Wasserstandes in der Laptewsee. / The satellite mission GRACE (Gravity Recovery and Climate Experiment) observes the earth's gravity field on temporal scales of a few days to several weeks and spatial scales of a few hundred kilometers with high accuracy. A large part of the variations of the gravity field originate from hydrological mass changes on the continents. The dissertation discusses the determination of hydrological mass variations from GRACE for the Siberian water systems of the rivers Ob, Yenisey, Lena and Kolyma. The mass variations from GRACE data are combined with atmospheric data of the NCEP reanalysis to calculate the freshwater fluxes in the Arctic Ocean. The freshwater fluxes strongly influences the salinity and the oceanographic regime of the Arctic Ocean. In turn, the Arctic Ocean controls the global thermohaline circulation which is very important for the global climate. Because these large currents of the ocean influence the global climate, the changes of the freshwater fluxes in the Arctic Ocean are an important factor for the global climate change. The runoff can be measured pointwise with high temporal resolution, but measurements in the high latitudes are difficulty and expensive. Independent methods to measure the mass changes in the Arctic can help to determine the freshwater fluxes on large spatial scales, and contribute to understand the coupled and complex processes of the Arctic. Until present, the complex error structure of the GRACE data are not fully understand. The dissertation examines the errors and analysizes the leakage caused by the limited spectrum of the Stokes coefficients. A proposal for a solution will be discussed. The following steps are important: Expanding the GRACE data with adequate terms of degree one; Valuation of leakage errors because of the limited spectrum. Leakage due to oceanographic signals of the Arctic Ocean are small (< 1%). Leakage errors due to signals on land produces relative errors of basin averages of 8-17%. Beyond that, the largest errors are caused by the coefficients of higher degree. Filtering is an effective method to damp the error signals. In addition to the common filters described in the literature, a filter method, called composite filter, was created. Significant structures from hydrological models can be deteceted in the GRACE data without any other filtering. Only the residual signals should be filtered by using one of the common filters. In comparison to the common filters, the composite filter represents the signal strength, the signal structures, the amplitude and the phase of the saisonal signal on the continents much better. Combining hydrological mass variations from GRACE data with atmospheric data (for example the NCEP reanalysis) the runoff of the four Siberian river systems can be calculated. The validation of the calculated runoff using observations leads to a good agreement (83% for Yenisey and Lena). Furthermore, it is possible to combine the runoff of a river system with measurements of water level and salinity in the Arctic Ocean. The high runoff of the Lena river system in spring is visible in the water level changes in the Laptev sea.

The growing global population and the ongoing loss of arable soils increase the pressure on agricultural production. In conjunction with climate change, this causes new challenges for agricultural production systems worldwide and requires a more sustainable approach for the future. The concept of ‘sustainable land management’ (SLM) is known as a concretisation of the sustainable development goals in the field of agriculture. The Western Siberian grain belt covers 1 million km² in Asiatic Russia and is of global importance for agricultural production as well as an important carbon sink and of international interest for biodiversity preservation. The work was conducted as part of the interdisciplinary German-Russian SASCHA project, which focused on SLM strategies at the intersection of climate change and land-use change in Tyumen region of Western Siberia. The objective of this work was to identify strategies for sustainable agricultural land management in Western Siberia with a focus on arable farming issues. Therefore, specifically the following research questions were addressed: (i) What does the history of agricultural land use across the Western Siberian grain belt tell us for developing future strategies? (ii) How can the eco-efficiency of Western Siberian cereal cropping systems be increased under the strain of changing climatic conditions? (iii) Is soybean cultivation capable of diversifying crop rotations in the southern part of Western Siberia? Triggered by the dissolution of the Soviet Union and the collapse of the state farm system, massive land-use changes took place in the region. A normalised input-oriented intensity index was developed to quantify these changes and patterns in land-use intensity (LUI). Based on subnational, annual statistical data, two separate indices for cropland and grassland were calculated and applied on two spatial scales (provinces and districts). The spatio-temporal analysis showed significant opposite trends: decreasing intensity on grassland by -0.015 LUI units per year and intensification on cropland by +0.014 LUI units per year. The land-use changes that accompanied the post-Soviet transition from a planned to a market-driven economy also implied substantial socio-economic consequences for agricultural production. Based on the LUI analysis, locally adapted SLM scenarios were developed for Tyumen province and priority areas for implementation were identified. The findings clearly showed the need for having a different SLM strategy for grassland (predominantly used by livestock of households) and cropland (predominantly managed by large agricultural enterprises), which have to be addressed specifically by the different land users. Two major strategies were derived for the Western Siberian grain belt: low-intensity grazing for grassland conservation and sustainable intensification (SI) on cropland instead of cropland expansion. The system of conservation agriculture is a known possibility for SI in dryland cropping systems. Particularly under climate change predictions of drier and warmer growing conditions, no-till farming could be a promising way to increase eco-efficiency in Western Siberian cereal production systems. Therefore, a full-factorial split-split-plot field trial was conducted on a farmer’s field to test adaptations of tillage (usual conventional tillage ‘CT’ vs. no-till ‘NT’), seeding depth (usual deep 6.5 vs. shallow 4.5 cm) and seeding rate (usual high 600 vs. reduced 450 grains m-2) for the potential to increase water use efficiency and grain yield. Results from two above-average wet and cold growing seasons showed significantly better soil water storage of NT (+40 %) and no adverse effect on spring wheat grain yield and grain quality. Impacts of variations in seeding rate and seed placement were less pronounced. The highest yields of 3.19 and 3.82 t ha-1 were observed with NT treatment in 2014 and 2015, respectively. Other alternatives implemented to increase eco-efficiency of dryland cropping systems are enhanced fertilizer strategies. In Western Siberia, nitrogen (N) fertilizers (urea or ammonium-nitrate ‘Selitra’) in cereal production are commonly banded during sowing directly into the seed furrow. The performance of a new kind of slow-release fertilizer was tested in a field trial under on-farm conditions. A modified urea with silicate coating and urease inhibitor was compared in four N-levels (25/50/75/100 %) to 100 % of conventional urea, 100 % of Selitra and an unfertilized control in RCBD. Results showed significant differences in soil nitrate availability but no differences in ammonium release and no significant impact on grain yield or quality. From the results of this field trial there seemed to be no beneficial advantage of the tested novel slow-release fertilizer so far. More field site years and further improvements of the laboratory-scale fertilizer production are needed for scientifically founded results. Climate change is likely to considerably affect future growing conditions in regions around the current high-latitude boundaries of agricultural production. Specifically for soybeans, this leads to a northwards shift of the northernmost limit for cultivation. Therefore, the effect of soybean seed inoculation with Bradyrhizobium japonicum was investigated in comparison to an untreated control in a small-scale split-plot field trial under high latitude conditions. Leaf chlorophyll content by SPAD-meter readings was used as proxy for biological nitrogen fixation. Inoculation was always successful, since nodulation took only place in plots with seed treatment. Effect sizes of SPAD-values were significantly positive at beginning of seed filling but did not differ earlier. Except for the warmest site year, inoculation had no impact on seed yield and protein yield. Under cold growing conditions of high latitude regions, temperature sums seemed to limit soybean yield and the effectiveness of inoculation with B. japonicum. To implement soybeans as legumes in crop rotations, nevertheless, inoculation is mandatory, since soils in high latitudes lack soy-specific rhizobia bacteria. The trials and studies compiled in this thesis are examples of contributions to SLM strategies on varying spatial and temporal scales. Besides all the promising benefits of the described SI applications, some drawbacks must be considered: NT and CA often result in increased herbicide applications, genetically modified varieties (GMO) and herbicide resistances. Diverse crop rotations including legumes, however, would be a base for resilient cropping systems with a reduced reliance on a single herbicide. Moreover, Western Siberia has a great potential to become a key contributor to non-GMO dryland cropping. Even though the focus of this thesis was on agronomic strategies, the integration of livestock and arable farming is crucial for sustainable agriculture. The agricultural system of the Western Siberian grain belt could considerably benefit from crop-livestock integration by better soil fertility and enhanced nutrient management. The current observed trend of cropland intensification, however, will require increased attention paid to the sustainability of Siberian arable farming. Considering the forest steppes’ peculiarities and the unique land-use history, SI implemented on cropland and a moderate grazing regime on grassland seems to be the best combination for SLM across the Western Siberian grain belt.

Dans un contexte de changement global, prédire l’évolution de la productivité de la végétation dans le sud-ouest (SO) Sibérien reste un défi du fait d’incertitudes fortes sur les processus régulant la disponibilité en eau et en nutriments. Nous avons mis en évidence des relations entre cycles biogéochimiques, climat et propriétés du sol sur six sites contrastés.La croissance radiale des tiges de peuplier est principalement sensible au bilan hydrique du sol en forêt de steppe, au sud du SO Sibérien, alors qu’elle est stimulée par de hautes températures estivales en sub-taïga, dans le nord de la région.Des mesures de terrain et des simulations du bilan hydrique du sol ont montré que la fonte des neiges est importante pour la recharge des réserves hydriques du sol au sud. Au nord, ces réserves sont souvent rechargées en automne. La fonte des neiges est alors associée à du drainage. De plus, au nord, une épaisse couverture de neige protège le sol du gel en hiver. La distribution des racines fines est plus profonde en forêt de steppe qu’en sub-taïga, impactée par le déficit hydrique et le gel.L’homogénéité du statut en phosphore (P) des sols dans le SO Sibérien montre qu’il n’est pas encore très impacté par la pédogénèse. Les stocks en P élevés, notammen tles formes disponibles pour les plantes, suggèrent que le P n’est pas et ne sera pas limitant dans le futur.La décomposition des litières aériennes et la libération de l’azote (N) sont plus rapides en sub-taïga qu’en forêt de steppe. Un fort drainage pourrait expliquer un transfert profond du N dans les sols en sub-taïga. Cependant ces sols semblent efficaces pour retenir le N, limitant les pertes pour le système sol–plante. / Predicting the evolution of vegetation productivity in SW Siberia in the contextof global change remains a challenge because of major uncertainties concerningthe biogeochemical cycling and the plant-availability of water and nutrients. Weprovided insights on their relation to climate and soil properties, investigating sixcontrasting sites.Aspen stem radial growth is mainly sensitive to soil water budget in the foreststeppezone established in the south of SW Siberia while it is enhanced by highsummer temperatures in the sub-taiga, in the north of the region.Field measurements and water budget simulations revealed that snow-melt isimportant re-filling soil water reserves in the south. In the north, these reservesare mostly re-filled in autumn and snow-melt is associated with drainage. A thicksnow-pack also prevents soil from freezing in winter in the sub-taiga. Water deficitand soil freezing largely impact the distribution of fine roots within the soil profilewhich is deeper in forest-steppe than in sub-taiga.The homogeneous soil phosphorus (P) status in the region investigated revealedthis nutrient has not been yet very impacted by contrasting soil processes. High Pstocks, and in particular plant-available forms, suggest P is unlikely to be limitingunder current and future conditions.By contrast, we found differences in nitrogen (N) status. Above-ground litterdecay and the release of N occurs faster in sub-taiga than in forest-steppe. Higherdrainage may explain deeper N transfer in sub-taiga soils. However, sub-taiga soilsalso seem to be efficient in retaining N, limiting losses from the soil–plant system.

RESUMÉ V ANGLICKÉM JAZYCE Since the 1980s, a revival of religious traditions, whose continuity was disrupted considerably in the Soviet-era Russia, has been in motion in the entire area of Siberia and Central Asia, among the so called 'rooted nations'. While major religious groups, such as buddhism and islam, could successfully pick up the threads of their religious traditions thanks to their written resources; religions based mainly on oral transmission are facing the opposite situation, shamanism not being an exception. Intense tension coming from the spirituality of their own ethnic traditions, which spontaneously opened after many years of the Communist secularization, in the case of shamanism hit the barriers of how to adequately re- establish the disrupted traditions (lack of living bearers and experts on their own traditions, initiated and uninitiated shamans, and other ceremony specialists, ignorance of symbolism). The whole process of rebirth, revival or revitalisation of shamanism is entirely consistent with the context of current issues concerning constituent societies, which naturally carries the legacy of Soviet culture. Political and economic changes in the post- Soviet space also enabled the bearers of traditions to become open to a wide range of new influences from abroad. Revitalization...

No / We report here the genome sequence of an ancient human. Obtained from approximately 4,000-year-old permafrost-preserved hair, the genome represents a male individual from the first known culture to settle in Greenland. Sequenced to an average depth of 20x, we recover 79% of the diploid genome, an amount close to the practical limit of current sequencing technologies. We identify 353,151 high-confidence single-nucleotide polymorphisms (SNPs), of which 6.8% have not been reported previously. We estimate raw read contamination to be no higher than 0.8%. We use functional SNP assessment to assign possible phenotypic characteristics of the individual that belonged to a culture whose location has yielded only trace human remains. We compare the high-confidence SNPs to those of contemporary populations to find the populations most closely related to the individual. This provides evidence for a migration from Siberia into the New World some 5,500 years ago, independent of that giving rise to the modern Native Americans and Inuit.

Plurale Weltinterpretationen praktizieren wir täglich, meist ohne uns darüber bewusst zu sein. Zustande kommen sie durch die gleichzeitige und gleichwertige Existenz verschiedener Modelle der Weltinterpretation. Sie sind Produkte menschlicher Schöpferkraft und stehen als parallele Realitäten einander ergänzend und einander widersprechend nebeneinander. Das Buch führt am Beispiel der Tyva Südsibiriens in zwei Modelle der Weltinterpretation und in die Praxis des Umgangs mit ihnen ein. Es zeigt, wie einzelne lokale Akteure zwei von mehreren Modellen flexibel zum Einsatz bringen, um Situationen zu deuten und in ihnen zu handeln. Es wird deutlich, welchen Regeln die Tyva dabei folgen, welche Gründe sie leiten und welche Folgen sie zu tragen haben. Das Ergebnis ist ein Bild zeitgenössischer Kultur, das der gegenwärtig gegebenen Flexibilität und Pluralität des menschlichen Deutens, Handelns und Verhaltens gerecht wird. / Plural World Interpretations are part of our everyday lives, even if we are not aware of the fact. They result from the simultaneous existence of different but equal models for interpreting the world we live in. These models are the product of human constructivity and co-exist as parallel realities, complementing and contradicting each other. Based on fieldwork among the Tyva of southern Siberia, the book discusses the practice of dealing with this multiplicity of world interpretations and shows how individual actors oscillate flexibly between two of many possible models for interpreting specific situations and act on them. The rules Tyvans apply in varying contexts, the reasons behind their choices and the consequences they have to deal with, are analysed. The result is an account of contemporary culture that explores the flexibility and plurality of human interpretation, action and behaviour. / Мы используем множественные интерпретации мира (нем. plurale Weltinterpretationen) ежедневно и, в большинстве случаев, неосознанно. Осуществляется это за счёт одновременного и равноценного сосуществования различных моделей мировоззрения. Они являются продуктом творческой деятельностей человека и сосуществуют в качестве параллельных реальностей, дополняя и, одновременно, противореча друг другу. На примере тувинцев Южной Сибири данная книга знакомит с двумя моделями мировоззрения, а также с практикой их применения. Показывается, как локальные акторы гибко применяют две из существующего множества моделей: и для того, чтобы действовать в складывающихся ситуациях, и чтобы толковать их. Станет понятным, каким правилам при этом следуют тувинцы, какими мотивами руководствуются и какие это имеет последствия. Результатом явится картина современной культуры, которая будет отвечать имеющимся на данный момент запросам гибкости и многообразия в мировоззрении, действиях и поведении человека.

Protestants often think that 1he ROC has no mission just because Orthodoxy pays to more attention to Service life. We tried to understand motives, goals and objectives of the ROC missionary activity. We found out that the ecclesiologic way of thinking was the basis missionary idea of the eastern missionary practice and it showed itself differently in special historical moments. This work divides the whole history of the Orthodox Church in Russia (XI - XX centuries) into 3 periods of mission and makes its brief survey and analysis. In the first period (XI-XVI) only single monks-colonialists realized the Great Commission among Finnish tribes and russifed it Only certain people used the methods of well planned contextualizating mission, like Stephen of Penn. During the second period (1552-middl.XIX) the ROC worked in close combination with the State to the detriment of the deep evangelization of natives. In the third period (the middle of XIX- the beginning of XX) the missionaries of Orthodox Missionary Society used all the achievements of the native and foreign missionary: contextualization, Liturgies in the national languages. enlightenment by schools of all levels, the training of national leaders, social work ets.

Cette thèse porte sur les représentations des peuples autochtones du Nord forgées par les films et téléfilms soviétiques de fiction. Mobilisant plusieurs approches — l’analyse filmique, l’histoire culturelle du cinéma, l’histoire des représentations et l’histoire politique soviétique —, elle confronte les films à des sources non-films (presse, archives papier, entretiens), afin de mettre en lumière la construction d’une subjectivité et d’un regard. Il s’agit également de décortiquer la fabrication des représentations, dans ses dimensions à la fois les plus concrètes et les plus symboliques. En ce sens, la question de la participation ou de la non-participation des autochtones à la création de leur image filmique, que ce soit devant ou derrière la caméra, constitue une autre interrogation centrale. Les représentations filmiques des peuples du Nord, tiraillées en permanence entre visions du « progrès » et de l’« authenticité », opèrent à l’écran comme autant d’images qui permettent à l’Union soviétique d’évaluer sa propre perception de la modernité. Des années 1920 aux années 1980, les figures cinématographiques autochtones circulent entre deux pôles d’un continuum, qui va de l’incarnation d’une arriération à éliminer au nom de la soviétisation à celle d’une harmonie avec la nature, désormais perdue ou menacée. Par ailleurs, en prenant en compte la question de la contribution des autochtones à la création de leur propre image, cette thèse s’attache à montrer que le film constitue un espace complexe, où plusieurs lectures et usages sont possibles selon la position des participants. / This thesis focuses on the representations of indigenous peoples of the North in Soviet fiction films and made for TV movies. Mobilizing several approaches — film analysis, the cultural history of cinema, the history of representations and Soviet political history — it confronts films with non-film sources (press, paper archives, interviews) in order to highlight the construction of a subjective point of view. It also studies the production of these representations, in both its most concrete and symbolic dimensions. The issue of the participation or non-participation of indigenous peoples in the creation of their image on film, whether in front of or behind the camera, is another central question. The filmic representations of the peoples of the North, constantly torn between visions of “progress” and “authenticity,” operate on the screen as images that allowed the Soviet Union to evaluate its own perception of modernity. From the 1920s to the 1980s, images of indigenous people shifted along a spectrum ranging from the incarnation of backwardness to be eliminated in the name of Sovietization to the embodiment of harmony with nature, now lost or threatened. Moreover, taking into account the question of the contribution of the indigenous people to the creation of their own image, this thesis demonstrates that cinema became a complex space, where different readings and uses were possible according to the position of the participants.
