Title Ecosystem physiology responses to global change
Date 1999
Description Most ecosystems exposed to double ambient C02 show higher peak season net carbon uptake than those growing at current-ambient C02. For grasslands, above-ground biomass increased by an average of 14%, although individual responses for a given system and year range from negative to +85%. The wide range of the biomass response shows the highly interactive nature of the C02 response with other environmental factors, including water and nutrient availability, and temperature. For instance, low-temperature dominated systems, such as alpine grassland, Arctic tundra, and cool climate coniferous forest trees, are among the least responsive to elevated C02 , showing in some instances no growth response and complete acclimation of peak season gas exchange after a few years.
