To accomplish the survey seeking to evaluate the problems of protected territories, conditions and identify the relevance of protected territories selection. The methodology of research: Accomplish the research there were used methods of literature sources analysis, statistical data analysis and questionnaire survey analysis. Seeking to investigate the planning, protection and usage of protected and recreational territories, there were accomplished Prienai district protected terrritories analysis, discussed recreational territories. There is presented the results of questionnaire survey – protected territories vacationing approach to these territories and possibility to arrange protected territories selection. The results of research: ● There were thoroughly analysed Prienai district protected territories in the first part of work; ● In the second part of work, there was discussed tourism facilities, analysed Prienai district basis of estate data, it was revealed, that 70 percent district‘s estates are not used, only...

Elevated toxaphene levels have been reported in the biota of the Arctic. The purpose of this study is to measure total toxaphene levels in food samples commonly consumed by the Canadian Inuit and study the relationship between concentrations of total toxaphene and individual congeners. A total of 127 Inuit food samples were collected for toxaphene analysis. Total toxaphene and the specific toxaphene congeners including Parlar #26, #40/41, #42, #44, #50 and #62 were detected in the food samples. Total toxaphene concentrations ranged from 13 to 2800 ng/g and various congener concentrations ranged from 0 to 610 ng/g. Concentrations of total toxaphene were strongly correlated with congener concentration in marine mammals and weaker in fish. The sum of congeners Parlar #26, #50 and #62 accounted for 0--15% of total toxaphene in fish and 0--66% in marine mammals. Regression models were used to estimate total toxaphene based on individual or combinations of congener concentrations. Dietary intake was estimated to be 1.07 and 0.78 mug/kg body weight per day in Chesterfield Inlet and Igloolik. Our results show that there is no general conversion factor that can be used to estimate total toxaphene concentrations based on congener measurements.

Over 60% of the population in K'asho Got'ine, NWT, obtained less than 2/3 of the Recommended Nutrient Intakes (RNI) for vitamin A and calcium, as reported in a previous nutritional assessment. Focus group discussions and a food preference assessment were conducted with adults in order to identify the cultural, ecological, and socioeconomic factors (food attributes) as well as the individual preferences which influence the consumption of vitamin A and calcium-rich traditional and market foods in K'asho Got'ine. The major attributes limiting intakes of traditional food rich in vitamin A and calcium included: lack of equipment for hunting/fishing; seasonality; distance traveled to obtain certain foods; occasional unhealthy appearance of food; no hunter/fisher in the household. The major food attributes reported as barriers to greater intakes of selected market foods were: cost, freshness, intolerance to certain items, availability and unfamiliarity. Foods that received the highest preference scores were rabbit liver, loche liver, and Canada goose meat (smoked/dried) for vitamin A-rich foods and connie eggs, rabbit flesh, woodland and barrenland caribou head for calcium-rich foods. Criteria for selection of traditional and market foods to promote in the community included: (1) convenience of the food; (2) difficulty to overcome barriers to increasing food consumption; (3) concentration level of contaminants in certain traditional food; and (4) food preference score. This study identified available and underutilized traditional and market foods rich in vitamin A and calcium which are most acceptable to the community, and may be promoted in future nutrition intervention programs.

Rates of carbon and peat accumulation were studied in a series of peat landforms within discontinuously frozen peatlands near Fort Simpson, Northwest Territories. An extended distribution of the White River volcanic ash layer was used as a chronostratigraphic horizon to ensure a consistent time span of peat deposition among peat cores and to allow a large core sample size without the expense of radiocarbon dating. Apparent recent carbon accumulation rates measured over the past 1200 years were not significantly different among rich fen, peat plateau, and collapse fen (means 13--14 g C M-2 yr-1). Poor fen and bog mean accumulation rates were 20--22 g C M-2 yr -1 and were not significantly different from each other. Microtopography and water table position appear to be important controls on both carbon and vertical peat accumulation rates. A regional survey incorporating measurements from other parts of the southwestern Northwest Territories and the southeastern Yukon shows rates similar to those near Fort Simpson. / The aggradation of permafrost results in 50 and 65% decreases in carbon and vertical peat accumulation rates, respectively. Carbon and peat accumulation continue to decrease significantly with both increasing permafrost maturity and the number of ground fires. The internal degradation of permafrost results in nearly a doubling in carbon accumulation rates, yet permafrost degradation at the margins of a peat plateau results in carbon accumulation rates similar to the peat plateau. / Clymo's (1984) carbon accumulation model was applied to cores from each landform in addition to a core spanning the entire developmental history of the peatland. Results indicate that true carbon accumulation and sequestration efficiency rates in ombrotrophic peatlands are lower in the upper Mackenzie Valley than for other boreal regions, primarily owing to high decomposition rates. The cessation of carbon accumulation is being approached. The model also serves to highlight the dangers of using apparent and true carbon accumulation rates interchangably. / Apparent and true carbon accumulation rates are significantly lower than published rates from other parts of northern Canada, Finland, and the Former Soviet Union. Low and variable summer precipitation in the region may be a significant factor through increased aerobic decomposition and/or decreased plant production caused by moisture stress.

In this fieldwork study of the 1975 Kam Tin jiao, Chapter 1 discusses the setting, showing the social system of Kam Tin, analysed in terms of genealogical and community aspects. The discussion of the genealogical aspects shows that Kam Tin does not conform to the standard model of the "lineage". The occupational structure of one of the Kam Tin villages is discussed, as well as the population of the local area. Finally, a brief introduction to the jiao, in Kam Tin a decennial ritual, is provided, showing the genealogical and community based aspects of its organisation and performance. Chapter 2 treats the history and mythology of the Kam Tin jiao, explaining the circumstances of the early Qing history which led to its foundation. Chapter 3 examines the organisation of the jiao in terms of committee membership, funding, and the ritual timetable. Chapter 4 discusses the background and organisation of the ritual practitioners. These are the Ritual Leaders (chosen through a block throwing competition in the temple associated with the jiao) and the Taoist priests. Chapter 5 discusses the preparatory rituals of the jiao, including the two rites of Memorial presentation. The relationship between the preparatory rituals and the main rites of the jiao is delineated. Chapter 6 discusses the arrangement of the ritual area before the jiao's major rites. Chapter 7 continues with a chronological description and analysis of the main rites of the jiao. Chapter 8 discusses the jiao rites taking place after the period of abstention from certain kinds of foods and sexual relations. This chapter discusses the rationale for the collection and return of divinities from specific sites during the course of the jiao. Chapter 9 concludes the discussion by analysing the Kam Tin jiao both comparatively and on its own terms. The jiao is shown to be a worship of deities and an act of salvation and/or placation for hungry ghosts, aimed at securing well-being and fortune for the community. On another level of analysis, however, the rites in Kam Tin are a re-ordering of an imperfect society.
