Rapid changes in delta 13C of ecosystem-respired CO2 after sunset are consistent with transient 13C enrichment of leaf respired CO2

Rapid changes in delta 13C of ecosystem-respired CO2 after sunset are consistent with transient 13C enrichment of leaf respired CO2

times The CO2 respired by darkened, light-adapted, leaves is enriched in 13C during the first minutes, and this effect may be related to rapid changes in leaf respiratory biochemistry upon darkening. We hypothesized that this effect would be evident at the ecosystem scale.
