Arctic and Alpine Plant Life Cycles
The purpose of this review is to bring together recent information and theories on the adaptive mechanisms which enable plants to survive and function in environments with cool, short summers and cold, long winters-save for tropical alpine environments where "winter" comes nearly every night­ and, where possible, to relate these findings to the pattern of species and communities in different tundras.
Microclimate control of growth rates and habitats of the boreal forest mosses, Tomenthypnum nitens and Hylocomium splendens
Survivity and growth of Tomenthypnum nitens is limited by evaporation stress in habitats where ground water is not available, and Feather mosses are limited by radiation damage and evapation stress in open habitats, by depression of net assimilation and other deleterious effects of saturation in wet habitats.
Patterns of water use and the tissue water relations in the dioecious shrub, Salix arctica: the physiological basis for habitat partitioning between the sexes
It is conjecture that selection maintaining the intersexual differences may be related to different costs associated with reproduction that can be most easily met through physiological specialization and spatial segregation of the sexes among habitats of differing conditions.
Environmental regulation of nitrogen fixation in a high arctic lowland ecosystem
This study examined spatial and temporal variation in cyanobacterial nitrogen fixation and the environmental regulation of this variation at Truelove Lowland, Devon Island, N.W.T. Acetylene reduction
Forest Vegetation of the Montane and Subalpine Zones, Olympic Mountains, Washington
One of the last frontiers for large scale ecological research in the United States has been the Pacific Northwest, but until the late 1950's there had been few basic ecologic studies especially in the mountains near the coast.
Studies of flowering, germination, and seedling survival were conducted in various stable and unstable soil (surface scraped and surface tilled) sites on King Christian Island, N.W.T., Canada.
