| [echinococcosis in the nenets autonomous okrug]. | the paper presents results of an immunological screening of the population from the nenets autonomous okrug of the arkhangelsk region for echinococcosis. a high level (8.4 +/- 1.0%) of seropositivity of the population has been found to echinococcus antigens. occupational groups, such as reindeer-breeders, domestic servants in the tent of skins, hunters, fur-farmers, furriers) have been identified to be mostly at high risk for echinococcus infection. some animal species have been demonstrated to ... | 1989 | 2533318 |
| [the assessment of the epidemiologic situation of echinococcosis in the nenets autonomous okrug based on data from a dynamic serologic examination of the population]. | paper presents the riha and eia data of an annual 3-year survey of populations of two reindeer breeders' settlements in the nenets autonomous okrug of arkhangelsk province with the use of intact echinococcus antigen (riha) and fractions of echinococcus multilocularis antigens (eia). in 1984-1986, seropositivity has been established by 2 immunoassays for 98 (21.6 +/- 1.9%) out of 454 apparently healthy subjects. the annual echinococcus invasion rate in population varied within 2.8-3.7%, as estima ... | 1989 | 2534151 |
| finding the way: a critical discussion of anthropological theories of human spatial orientation with reference to reindeer herders of northeastern europe and western siberia. | in anthropology, research on human spatial orientation (wayfinding) has centered on two conflicting theories: the "mental map," whereby humans build abstract cognitive representations of the spatial relations between objects, and "practical mastery," which rejects the idea that such abstract representations exist and, in its most developed form, suggests that wayfinding is a process of moving from one recognized visual perspective (vista) to another (transitions between vistas). in this paper we ... | 2009 | 19579354 |
| high resilience in the yamal-nenets social-ecological system, west siberian arctic, russia. | tundra ecosystems are vulnerable to hydrocarbon development, in part because small-scale, low-intensity disturbances can affect vegetation, permafrost soils, and wildlife out of proportion to their spatial extent. scaling up to include human residents, tightly integrated arctic social-ecological systems (sess) are believed similarly susceptible to industrial impacts and climate change. in contrast to northern alaska and canada, most terrestrial and aquatic components of west siberian oil and gas ... | 2009 | 20007776 |
| traditional living habits of the taz tundra population: a paleoparasitological study. | an excavation of the vesakoyakha ii-iv and nyamboyto i burial grounds was conducted during the 2014 field season, and soil samples from intact burials dating from the 19th and 20th centuries, respectively, were analyzed to determine interactions between parasites and host/vectors. considering the discovery of diphyllobothrium sp. and taenia sp. eggs in soil samples from the pelvic region, diphyllobothriasis was the most frequent helminthic infection among the taz nenets. the nyamboyto nenets mai ... | 2016 | 27853118 |
| sea ice, rain-on-snow and tundra reindeer nomadism in arctic russia. | sea ice loss is accelerating in the barents and kara seas (bks). assessing potential linkages between sea ice retreat/thinning and the region's ancient and unique social-ecological systems is a pressing task. tundra nomadism remains a vitally important livelihood for indigenous nenets and their large reindeer herds. warming summer air temperatures have been linked to more frequent and sustained summer high-pressure systems over west siberia, russia, but not to sea ice retreat. at the same time, ... | 2016 | 27852939 |
| effects of increase in temperature and open water on transmigration and access to health care by the nenets reindeer herders in northern russia. | the indigenous nenets reindeer herders in northern russia annually migrate several hundred kilometers between summer and winter pastures. in the warming climate, ice-rich permafrost and glaciers are being significantly reduced and will eventually disappear from parts of the arctic. the emergent changes in hydrological cycles have already led to substantial increases in open water that stays unfrozen for longer periods of time. this environmental change has been reported to compromise the nomadic ... | 2013 | 23971018 |
| high prevalence of lactase non-persistence among indigenous nomadic nenets, north-west russia. | the frequency of adult-type hypolactasia (lactase non-persistence) varies widely among different ethnic groups. the cultural historical hypothesis assumes a link between the occurrence of hypolactasia and the distribution of dairy farming. the nomadic nenets have been reindeer herders for generations and have therefore not consumed any dairy products. the hypotheses here was that the prevalence of lactase non-persistence (-13910 c/c genotype) among nenets people having four nenets grandparents i ... | 2012 | 22564469 |
