Fire Effects on Plant-Soil System in Taiga Forests in Interior Alaska
Nutrient availability is assumed to increase and stimulate ecosystem productivity by global warming in many terrestrial ecosystems. Northern forests contain significant global carbon pools, and fire is a common component in these forests. Thus, concerns have recently been directed to fire effects on...
