… tree ring, where the latter was found to be generally enriched in 13 C when compared with
the former (Helle & Schleser, 2004). Furthermore, the use of cellulose from tree rings … tree-ring …

… tree ring δ 13 C, we calculated intrinsic water use efficiency (W i ) and intercellular [CO 2 ] (c
i ). Our results showed that trees … that δ 13 C in tree rings of tropical dry forest trees may be a …

… To avoid any effect of long-term environmental changes, we chose tree rings formed
between 1965 and 1974 but by trees of different cambial ages (the age of the tree when the ring …

… Tree‐ring δ 13 C is often interpreted in terms of intrinsic water‐use efficiency (WUE) using a
… We examined whether intra‐ring δ 13 C could be used to assess variations in intrinsic WUE …

… ring width by using percentage of the ring width as a predictor. The space-for-time conversion
could then be performed because we knew the exact position of the cell within the tree ring …

… water use efficiency (WUE i ) of forests, but the magnitude of this effect and its interaction with
climate is still poorly understood. We combined tree ring … entire life of the trees. We used δ …

… The carbon isotope ratio (δ 13 C) in tree rings is commonly used to derive estimates of
the assimilation-to-stomatal conductance rate of trees, that is, intrinsic water-use efficiency (iWUE)…

… Measurements of the stable carbon isotope ratio (δ13C) on annual tree rings offer new …
assimilation to stomatal conductance, termed intrinsic wateruse efficiency (iWUE). We performed …

… water-use efficiency (WUE), which is the ratio of the uptake of carbon dioxide through photosynthesis
to the loss of water … We have used 13C measurements from tree rings, along with …

… each annual tree ring has its origin in the CO 2 of air, and O and H come from soil water and
… exchange with xylem water, which will push δD of tree rings back towards that of the source …
