North West Territories

In the extreme northernmost part of Canada, lying between North Latitudes 56° and 68° and West Longitudes 88° and 112°, is an area of about 400,000 square miles, which had up to the past two years remained geologically unexplored.In 1892 the Director of the Geological Survey of Canada sent the writer to explore the country north of Churchill River, and south-west of Lake Athabasca;in1893 the exploration was continued northward, along the north shore of Athabasca Lake

Seawalls, revetments and groynes designed to protect shorelines require normally timber, natural stone or concrete for their construction. In Tuktoyaktuk, none of these materials is available and to avoid excessive costs, an alternative form of construction, using long sausage shaped tubes filled with sand, was devised on an experimental basis. Tuktoyaktuk is situated on the eastern side of Kugmallit Bay in the Western Arctic at north latitude of 69 deg. 27' and west longitude of 133 deg. 02'. It is approximately 90 miles north of Inuvik and 1450 miles northwest of Edmonton (figure 1). The area is mainly comprised of a long, narrow, boot-shaped peninsula oriented in approximately north-south direction, a complex lagoon, which has been developed as a harbour, east of the peninsula and an island straddling the mouth of the lagoon (figure 2). Certain dwellings exist at the southern and southeasterly shores of Tuktoyaktuk Harbour. A large majority of the inhabitants reside in settlements developed on the peninsula and the southern area linking the peninsula with the mainland. Tuktoyaktuk is used as a transfer point linking the Mackenzie River barge transport with coastwide shipping serving the western arctic seaboard and inland settlements and bases. As a result of this the TCJK settlement has grown to be the largest of the western arctic coast settlements.

Hygienic Conditions

There are presented the results of a 21-year-old (1991-2012) monitoring of Hg concentrations and amounts of metals, including heavy and toxic, Zc(MnCrVNiCoCuAgZnPbSnMo) in soils of the zone of the exposure to emissions from Astrakhan gas complex (AGK), working from 1987 within a radius of 50 km. On those criteria for the period over 1997-2012 there was revealed a steady deterioration of ecological-hygienic conditions of the lands in the control zone. The spatial variability of this condition is largely controlled by the dispersion of the emissions by the prevailing easterly and southeasterly winds. The content of Hg in 2007, remote from AGK by 15 km, increased by 6-8 times on the leeward north-west territories, where the accumulation of the toxicant was 2.5 times more pronounced than in the windward Eastern and North-Eastern side. The significant role in the deterioration of sanitary-ecological state of the territory of the sanitary protection zone when dealing with Hg-containing (70-100 mkg/kg) commodity grey belongs to reblowing of particles and their eolian spread from places of storage, loading and transportation. In separate halos the content of Hg in the soil has reached 285 mkg/kg and become closer to the "target" safe level (300 mkg/ kg), adopted in Western Europe (zone AGK-30 km). The total amount of metals as in the near (up to 5 km of sanitary protection), so far (5-50 km) zones as in background sites has increased steadily. By 2012 in some places, remoted up to 30 km from AGK there were fixed already hygienically dangerous levels of total metals accumulation (up to Zc =34)

Extended Parental Care

Few studies of monogamous canids have addressed regurgitation in the context of extended parental care and alloparental care within family groups. We studied food transfer by regurgitation in a pack of wolves on Ellesmere Island, North West Territories, Canada, during 6 summers from 1988 through 1996. All adult wolves, including yearlings and a post-reproductive female, regurgitated food. Although individuals regurgitated up to five times per bout, the overall ratio of regurgitations per bout was 1.5. Pups were more likely to receive regurgitations (81%) than the breeding female (14%) or auxiliaries (6%). The breeding male regurgitated mostly to the breeding female and pups, and the breeding female regurgitated primarily to pups. The relative effort of the breeding female was correlated with litter size (Kendall's τ = 0.93, P = 0.01).
