Adaptations of Luzula confusa to the Polar Semi-Desert Environment
Luzula confusa is both morphologically and physiologically adapted to the polar semi-desert environment of the western Queen Elizabeth Islands. This species combines the more efficient graminoid photosynthetic system and a less drought-resistant mechanism with some of the cushion plant energy-trapping characteristics such as tufted growth form and persistence of dead leaves, with consequent thicker boundary layer. In this manner, the plant is abl…

Overwinter Phenology of Plants in a Polar Semi-desert
Arctic and temperate-latitude tundra plants must make efficient use of the growing season, because it is very short. A variety of leaf-development strategies permit growth in the cool summers. ... Winter phenology was observed under field conditions for 27 of 33 angiosperm species found on King Christian Island. ... The full significance of overwintering leaf condition and the variability of this pattern within the High Arctic needs further inves…
Susceptibility to Environmental Impact in the Queen Elizabeth Islands
Exploration for oil and gas is proceeding on a rapidly increasing scale in the Queen Elizabeth Islands, and the region needs therefore to be assessed comprehensively in terms of susceptibility of habitat to physical disturbance. ... The evaluation is however necessarily provisional, since only a small part of the total land area has so far been the subject of detailed biological description. Areas likely to be ecologically critical are delimited …
Origin and Significance of Wet Spots on Scraped Surfaces in the High Arctic
In the western Queen Elizabeth Islands, Northwest Territories, where most of the petroleum exploration in the High Arctic is being conducted, much of the low lying land is covered with sorted and non-sorted circles and polygons 0.5-2.0 m in diameter. ... Much of the oil-camp construction takes place on the coastal low-lands on polygonal surfaces composed of sandy to silty loams. When these surfaces are scraped and reworked for camp areas and air …
IBP High Arctic Ecosystem Study, Devon Island
The research in 1971 coctinued to emphasize the physical environment and the biological response of organisms on meadows (c.49 per cent of the lowland) and raised beach ridges (c. 15 percent of the lowland) in the Truelove Lowland.The lakes (22 percent) were not included in the studies and all data are expressed on the basis of a 3,300 ha.land area.As in 1970, the research was concentrated on a typical mesic meadow (soils, meteorology, primary pr…
Devon Island Programs, 1970
The Arctic Institute's research base on Devon Island was used by over twenty-five investigators and their field assistants during the 1970 summer field season, from late April to mid-September. There were two separately directed, but related, programs. One, a large integrated ecosystem study, was directed by L.C. Bliss of the University of Alberta and sponsored by the Canadian International Biological Program (IBP); the other was an Arctic Instit…
Adaptations of Arctic and Alpine Plants to Environmental Conditions
Discusses tundra environments, i.e. beyond the climatic timberline, mostly in Alaska, Canada, Greenland, and USSR, and various mechanisms used by plants in adapting to them. Despite a very short growing season with low air and soil temperatures, adverse wind effects, and a low nitrogen-utilization level, tundra plants are well adapted to their environment. They are apparently efficient converters of energy, due partly to their utilization of much…
Seed Germination in Arctic and Alpine Species
Account of germination tests made with the aim of ascertaining seed viability of plants from the arctic tundra of Alaska (near Umiat, 69 22 N, 152 10 W) and the alpine tundra of Wyoming. A greater proportion of the latter germinated (of 26 species, 21 i.e. 80%; of 36 arctic species, 22 or 61%); though individual species from both tundras showed a high percentage of germination. Conditions affecting germination, influence of light and darkness, we…
