Introduction Challenges for the Future: Arctic and Alpine Ecosystems in a Changing Worldnvironmentally, floristically, faunistically, metabolically, and sociologically. The Arctic has been predicted to warm more rapidly and to a greater extent than the rest of the biosphere (Maxwell, 1992). Also, these once pristine and relatively isolated places are now subject to considerable disturb

Recent Climate Patterns in the Arcticoth the Northern and Southern Hemispheres, as is the temporal pattern of temperature change. Thus, in the Northern Hemisphere, the coolest period of the past 100 years occurred in the early part of the 20th century; this was followed by a fairly abrupt warming during the 1920s, which culminated arou

Global and Regional Patterns of Climate Change: Recent Predictions for the Arcticuently, some of the radiation emitted to space through the top of the atmosphere emanates not from the surface but from within the atmosphere. As the intensity of radiation is proportional to the fourth power of the temperature of the emitter, and the atmosphere is mostly colder than the surface, th

Impacts of Climate Change on Demographic Processes and Population Dynamics in Arctic Plantsfew studies have addressed long-term responses such as biome redistribution (e.g., Emanuel et al., 1985a, 1985b; Prentice, 1993). Studies on an intermediate, population-orientated, level are largely lacking. Yet it is on this level that the physiological responses to the environment are integrated i
