Evolution of postglacial vegetation in the Western Laptev Sea region (Siberian Arctic)

On the basis of a detailed study of the pollen-spore spectra and a detailed radiocarbon chronology of a sediment core obtained from the western outer Laptev Sea shelf, the long-term and high-resolution changes of vegetation in the northwestern Laptev Sea region were reconstructed for the last 12.0 cal. ka. Three major phases in the development of paleoenvironments and vegetation on the surrounding hinterland and the exposed Laptev Sea shelf were recognized. The period between 12.0 and 10.3 cal. ka BP was characterized by predominance of grass-sedge and moss tundra. Rapid expansion of herbaceous tundra with dwarf birch and alder started at about 10.3 and lasted until 8.0 cal. ka. Pollen spectra from this time interval evidence the warmest and most favorable climate conditions. After 8.0 cal. ka mosses and lichen vegetation with scare herbs typical for the modern arctic tundra dominated. German: Auf der Grundlage detaillierter Pollen- und Sporenspektren aus einem 14C-datierten Sedimentkern vom äußeren Schelf des westlichen Laptewmeeres wurden die langfristigen und hochaufgelösten Veränderungen der Vegetation in den letzten 12 cal. ka in der nordwestlichen Laptewmeer-Region rekonstruiert. Es wurden drei Hauptphasen der Entwicklung von Umwelt und Vegetation im umgebenden Hinterland erkannt. Die Zeit zwischen 12,0 und 10,3 cal. ka BP war charakterisiert durch Riedgras- und Moos-Tundra. Rasche Ausdehnung der Kraut-Tundra mit Zwergbirke und Erle begann etwa um 10,3 cal. ka und dauerte bis 8,0 cal. ka. Pollenspektren aus diesem Zeitintervall beschreiben die wärmsten und besten Klimabedingungen. Nach 8,0 cal. ka dominierte die für die heutige arktische Tundra typische Moos- und Flechtenvegetation mit wenigen Kräutern

Momiji and the Method of Contemplation in the Environmental Education

Рассматривается проблема непрагматического взаимодействия человека с объектами природы на основе метода созерцания. Исследование проводилось в экосистемах городских парков Екатеринбурга во время осенних экологических экскурсий в сентябре 2017 года. Показано, что студенты приобрели опыт не- прагматического взаимодействия с объектами природы, проявили надситуационную активность при самостоятельной организации познавательной деятельности.This article deals with the problem of non-pragmatic interaction of human with nature objects on the basis of the method of contemplation. The study was conducted in ecosystems of Yekaterinburg city parks during the autumn ecological excursions in September 2017. It is shown that the students gained experience of non-pragmatic interaction with the objects of nature, showed not situational activity for self-organization of cognitive activity

Quaternary palynostratigraphy of the Pechora Sea

By combining the lithologic, original palynologic and published micropaleonthological data we reconstructed paleogeographical events On the Pechora shelf during the Younger Dryas and Holocene time. Our paleoenvironmental reconstructions are based On the regularities in formation of pollen-and-spores assemblages in the surface sediments of the Pechora Sea. The main stages in paleogeography of the Pechora Sea during the Late Pleistocene were emphasized. The Late Valdai sediments in the Pechora Sea region were accumulated under the influence of fluvioglacial flows probably from the melting ice cap on Kolguev Island and, also, coastal glaciers. Climate deterioration considerably changed coastal vegetation as reflected in the depleted taxonomic and quantitative composition of palynospectra. The pollen data suggest that Open steppe-like plant communities with Artemisia, Poaceae, Asteraceae and Caryophyllaceae dominated dry ecotopes On watersheds, whereas tundra-like communities with Betula nana, arctic Salix, Dryas, Saxifraga, Carex and Brassicaceae were common in more humid coastal lowlands. The overlying silts and loamy sands are believed to have been accumulated during early deglaciation, i.e., Older Dryas and Alleröd. During this phase the glacial sedimentation was rather rapidly replaced by a glaciomarine deposition. Progressive climate warming caused prominent changes in coastal vegetation. Discontinuous treeless tundra-steppe associations were replaced by dwarf and shrub ernik tundra. A "complex vegetation cover" of forest-tundra apparently existed in the northern part of the Kola Peninsula and in the Northern Dvina Lowland. By the end of the Alleröd alder-bushes and horsetails occupied riverbanks, and spruce occurred in the forest-tundra communities on the adjacent hinterland

Analytical survey of development directions of social labour sphere of urban settlement

The article shows the relevance of implementing the development processes and expanding the infoshere within the international standards of statistical accounting. It reflects methodological approaches to analytical processing of information resources characterizing the conditions and trends in developing modern urban settlement. The article also provides the dynamics on the a number of indexes of social labour sphere in Rostov-on-Don. It shows the practicability of forming the conception of the strategic development of the urban settlement based on official information resources. The article provides the comparative assessment of the position of Rostov-on-Don as the capital of the Southern Federal District on a number of indexes of social labour sphere regarding million-plus cities of Russian and regional capitals forming a part of the Southern Federal District.peer-reviewe

System integration of the educational process: the unity of the social and moral education

The subject of discussion was the system integration (development of integrated solutions) processes of social and moral education. The study proved that the society and the teacher in it act as a system integrator for generating the necessary conditions for the formation of the stereotype of prosocial behaviorПредметом обсуждения стала системная интеграция (разработка комплексных решений) процессов социального и нравственного воспитания. В ходе исследования было доказано, что социум и педагог в нем выступают как системный интегратор, генерирующий условия, необходимые для формирования стереотипа просоциального поведени

Eco Centric Bird-Watching as an Inclusive Method of Environmental Education

В статье обсуждается экоцентрический берд-вотчинг (bird-watching) — инклюзивный метод формирования приверженности к нормам экологической этики. Показано, что экоцентрический бердвотчинг основан на эмпирическом методе наблюдения, структурирован педагогическими технологиями, усилен посредством экосоциального компьютинга, позволяет достичь признаков сингулярности в эволюции социальной парадигмы в экоцентрическую. Представленная авторская разработка, успешно опробована в процессе осенне-зимних экологических экскурсий студентов Российского государственного профессионально-педагогического университета в городские парки г. Екатеринбурга в 2016—2017 учебном году.The article discusses eco centric bird-watching — inclusive method of achieving adherence to norms of environmental ethics. It is shown that eco centric bird-watching based on the empirical method of observation, structured educational techniques, enhanced by eco socialism computing allows you to achieve the characteristics of a singularity in the evolution of social paradigms into eco centric. It is presented the authorʼs development, which is successfully tested in the process of autumn-winter еecological excursions of the city by the students of the Russian state vocational pedagogical University into the city parks of Yekaterinburg during 2016—2017 school year
