Context The carbon isotope composition of the CO2 efflux (δ13CE) from ecosystem components is widely used to in-vestigate carbon cycles and budgets at different ecosystem scales. δ13CE, was considered constant but is now known to vary along seasons. The seasonal variations have rarely been compared among different ecosystem components.Aims We aimed to characterise simultaneously the season-al dynamics of δ13CE in different compartments of two temperate broadleaved forest ecosystems.
