This includes fostering the wisest use of our land and water resources, protecting our fish and wildlife, preserving the environmental and cultural values of our national parks and historical places, and providing for enjoyment of life through outdoor recreation. The Shared Beringian Heritage Program at the National Park Service is an international program that rec- ognizes and celebrates the natural resources and cultural heritage shared by the United States and Russia on both sides of the Bering Strait.

[email protected] Hallingbäck, T. (2002). Globally widespread bryophytes, but rare in Europe. Portugaliae Acta Biol. 20: 11-24. The need to save not only globally threatened species, but also regionally rare and declining species in Europe is discussed. One rationale of red-listing species regionally is to be preventive and to counteract the local species extinction process. There is also a value in conserving populations at the edge of their geographical range and this is discussed in terms of genetic variation. Another reason is the political willingness of acting locally rather than globally. Among the rare and non-endemic species in Europe, some are rare and threatened both in Europe and elsewhere, others are more common outside Europe and a third group is locally common within Europe but rare in the major part. How much conservation effort should be put on these three European non-endemic species groups is briefly discussed, as well as why bryophytes are threatened. A discussion is given, for example, of how a smaller total distribution range, decreasing density of localities, smaller sites, less substrate and lower habitat quality affect the survival of sensitive species. This is also compared with species that have either high or low dispersal capacity or different longevity of either vegetative parts or spores. Examples from Sweden are given. Key words: Bryophytes, rarity, Europe, dispersal capacity, Sweden. Hallingbäck, T. (2002).

    Living in Two Places : Permanent Transiency In

    living in two places: permanent transiency in the magadan region Elena Khlinovskaya Rockhill Scott Polar Research Institute, University of Cambridge, Lensfield Road, Cambridge CB2 1ER, UK; [email protected] abstract Some individuals in the Kolyma region of Northeast Russia describe their way of life as “permanently temporary.” This mode of living involves constant movements and the work of imagination while liv- ing between two places, the “island” of Kolyma and the materik, or mainland. In the Soviet era people maintained connections to the materik through visits, correspondence and telephone conversations. Today, living in the Kolyma means living in some distant future, constantly keeping the materik in mind, without fully inhabiting the Kolyma. People’s lives embody various mythologies that have been at work throughout Soviet Kolyma history. Some of these models are being transformed, while oth- ers persist. Underlying the opportunities afforded by high mobility, both government practices and individual plans reveal an ideal of permanency and rootedness.

The intended quantity of family food parcels was produced in Petropavlovsk-Kamchatsky and Magadan, and distribution is ongoing in all four regions covered by the Appeal. Hygiene kits have also been procured for all the regions and have already been sent to Magadan for distribution. Adverse weather conditions are making air transport difficult and causing logistical constraints. The context The steady erosion of living standards and rise in unemployment associated with a decade of diffi- cult market transition and poor harvests in Russia has taken a high toll in terms of living conditions and brought with it economic inequality and heightened social instability which has been particu- larly devastating for the population of the Far North-eastern remote regions of Chukotka, Kamchatka, including Koryak okrug, and Magadan. Geographic isolation (air transport and dog sleds are the only ways to reach some remote polar areas for many months of the year) combbined with a harsh climate (with temperatures reaching -50 C during long winter months and +40 C in summer), poor infrastructure, a lack of economic diver- sity, the high cost of transport, the over-dependance on imports, and the loss of subsidies have all compounded the regions’ problems.

  • Mobility and Sense of Place Among Youth in the Russian Arctic

    Mobility and Sense of Place Among Youth in the Russian Arctic

    Mobility and Sense of Place among Youth in the Russian Arctic ALLA BOLOTOVA, ANASTASIA KARASEVA, AND VALERIA VASILYEVA Abstract: This article explores how the mobility of young people in- fluences their sense of place in different parts of the Russian Arctic. In globalization studies increasing mobility has often been set in oppo sition to belonging to place, and interpreted as diminishing local connections and ties. Recent studies show that the role of mobil- ity in shaping a sense of place is more complex. The Russian Arctic is often considered a remote, hard-to-access area, despite the fact that local residents have always been very mobile. We compare three case studies from across the Russian Arctic—namely, the Central Murmansk region, the Central Kolyma, and Eastern Taimyr—show- ing how mobility shapes differently young residents’ sense of place. These regions have a different population structure (urban / rural, polyethnic / monoethnic) and different transportation infrastructure, thus providing a good ground for comparing the relationships be- tween mobility and a sense of place in the Russian Arctic. Keywords: Magadan region, mobility, motility, Murmansk region, Russian Arctic, sense of place, Taimyr, transport infrastructure here are no roads in the North” is a common stereotype about “ the Russian Arctic.1 Social scientists working there often become annoyedT by this postulate, not only because it presumes an essential immobility of the local population that is far from reality, but also by the background idea that the Russian North is a uniform, homogeneous space that does not display significant differences across its several thousand kilometers. Anthropologists studying the Russian North face precisely the opposite problem: how best to compare the results of field research if social life varies so radically in different regions.

The mean was srnaller than that in high latitudes of th6 Eurasian Continent: However, regional variation was not recognized within Hok- and 5.2inOctober. The number of kaido. Tbe mean pumber of ¢ mbryos was 5.9 in June, 4.8 in August embryos tended to increase with advanoed age and increased body weight of females, but it decreased in females of 12 months old. Thus the declinein the number ofembryos in August and October was at- tributed to advanced ago in overwintered females and recmitnrent of young fernales to the population, There was no difference in the number ofembryos between primiparous females and multiparous ones, Tbe number of corpora lutea per pregnant female ranged from 2 to 14 and averaged 6.1. Prenatal loss ef embryos was found in 36.0% of the 439 pregnant females examined.

Quaternary Science Reviews, 53, 72-87. doi: 10.1016/j.quascirev.2012.08.004 http://www.sciencedirect.com/science/article/pii/S0277379112003046 1 Abstract During various periods of Late Quaternary glaciation, small ice-sheets, -caps, -fields and valley glaciers, occupied the mountains and uplands of Far NE Russia (including the Verkhoyansk, Suntar-Khayata, and Chersky Mountains; the Kolyma-Anyuy and Koryak Highlands; and much of the Kamchatka and Chukchi peninsulas). Here, the margins of former glaciers across this region are constrained through the comprehensive mapping of moraines from remote sensing data (Landsat 7 ETM+ satellite images; ASTER Global Digital Elevation Model (GDEM2); and Viewfinder Panorama DEM data). A total of 8414 moraines are mapped, and this record is integrated with a series of published age-estimates (n = 25), considered to chronologically-constrain former ice-margin positions. Geomorphological and chronological data are compiled in a Geographic Information System (GIS) to produce ‘best estimate’ reconstructions of ice extent during the global Last Glacial Maximum (gLGM) and, to a lesser degree, during earlier phases of glaciation.
