No diurnal variation in rate or carbon isotope composition of soil respiration in a boreal forest
Characterization of soil respiration rates and δ13C values of soil-respired CO2 are often based on measurements at a particular time of day. A study by Gower et al. (2001) in a boreal forest demonstrated diurnal patterns of soil CO2 flux using transparent measurement chambers that included the understory vegetation. It is unclear whether these diurnal patterns were solely the result of photosynthe
