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

Climate change and associated alteration of the growing season could therefore have a strong impact on the performance of arctic and alpine plants (Bazzaz, 1990; Galen and Stanton, 1995). Recent autecological studies (e.g., Eriksen et al., 1993; Molau, 1993b; Stenström and Molau, 1992) have sh
