Springtime ecosystem-scale monoterpene fluxes from Mediterranean pine forests across a precipitation gradient

What is it about?

-We quantified monoterpene (MT) fluxes in two pine forests across a rainfall gradient. -The drier site suffered a heat wave that lowered net daytime CO2 assimilation. -Both forests showed similar daytime standardized MT emission capacities. -Emission models overestimated MT fluxes under high temperatures of a heat wave. -Interaction of drought and high temperatures drives biogenic MT emissions.
