[1] The oxygen isotope content of nocturnal ecosystem respiration (dOR) was examined in forests along a precipitation gradient in Oregon, USA, to determine whether site-to-site variation in dOR was more strongly related to variation in d O of precipitation or to evaporative processes that isotopically modify water pools within ecosystems. Measurements were made over 4 years at sites ranging in ...
