✦ Synopsis


The general role of snow in the ecology of snow-covered systems is presented. A brief review on the interactions between snow and climate, and between snow and microorganisms, vegetation and animals is followed by a discussion on some of the processes which mediate nutrient cycling when snow lies on the ground. The in¯uence of snow on nutrient cycling and its importance in the overall biological productivity of snow-covered ecosystems is illustrated by the study of the dynamics of nitrogen (N). The topics include the assimilation of N by algae within snow cover, the gaseous emissions of CO 2 and N 2 O from soil under snow cover and the hydrologic export of N during snowmelt.
