The tundra biome is characterized by low biomass and species diversity relative to other biomes, and the spatial distribution of species of all groups is strongly structured by physical factors (Chapin and Körner 1995).

Changes in the extent or functioning of the boreal forest could substantially modify global climate through (1) release of its large stocks of soil carbon (Post et al. 1982; Kurz and Apps 1995), (2) changes in methane fluxes from peatlands (Reeburgh and

Related reviews have emphasized the response of freshwaters to changes in climate alone (Carpenter et al. 1992; Firth and Fisher 1992; Arnell et al. 1996; Cus
