Net Primary Production and Carbon Stocks for Subarctic Mesic-Dry Tundras with Contrasting Microtopography, Altitude, and Dominant Species
Udgivelsesdato: August, 2009 Mesic-dry tundras are widespread in the Arctic but detailed assessments of net primary production (NPP) and ecosystem carbon (C) stocks are lacking. We addressed this lack of knowledge by determining the seasonal dynamics of aboveground vascular NPP, annual NPP, and whol...

Ecosystem C and N stocks were 2100-8200 g C m -2 and 80-330 g N m -2 , respectively, stored mainly in the soil turf and in the fine organic soil.

Udgivelsesdato: August, 2009 Mesic-dry tundras are widespread in the Arctic but detailed assessments of net primary production (NPP) and ecosystem carbon (C) stocks are lacking.
