The effect of elevated CO 2 , soil and atmospheric water deficit and seasonal phenology on leaf and ecosystem isoprene emission

Pegoraro, Emiliano; Potosnak, Mark J; Monson, Russell; Rey, Ana; Barron-Gafford, Greg; Osmond, C Barry

Description

Two cottonwood plantations were grown at different CO2 concentrations at the Biosphere 2 Laboratory in Arizona to investigate the response of isoprene emission to elevated [CO2] and its interaction with water deficits. We focused on responses due to seasonal variation and variation in the mean climate from one year to the next. In fall and in spring, isoprene emission rate showed a similar inhibition by elevated [CO2], despite an 8-10°C seasonal difference in mean air temperature. The overall...[Show more]
