What's the flux? Unraveling how CO2 fluxes from trees reflect underlying physiological processes

We report that the CO2 emitted from a stem is produced by physiological processes, but the challenge remains identifying what portion is produced by local tissues, which will facilitate much-needed mechanistic understanding of factors controlling autotrophic respiration.
