| [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 |
| human impacts on the tundra-taiga zone dynamics: the case of the russian lesotundra. | the tundra-taiga zone is considered not only as a natural ecotone, but as a unique fringe zone with socioeconomic peculiarities. this holistic approach enables us to analyze several significant types of human impacts (industrial impacts and those associated with renewable resources development, including traditional reindeer herding and human settlements) and their role in the displacement of the lesotundra zone. in russia, there is much evidence of deforestation and ecosystem degradation in dif ... | 2002 | 12374057 |
| [polymorphism of the mtdna control region in wild reindeer rangifer tarandus (mammalia: artiodactyla) from the european part of russia]. | genetic diversity ofwild reindeer (rangifer tarandus) inhabiting the european part of russia, including komi republic, arkhangelsk oblast, murmansk oblast, and the republic of karelia was characterized using sequence polymorphism of the mtdna control region. despite of currently low population number of wild reindeer, they were characterized by a high level of genetic diversity (pi = 0.018; h= 0.872 to 0.914). phylogenetic analysis showed close relationships between european reindeer and wild re ... | 2012 | 23113338 |
