Water stable isotopes (18O and 2H) are widely used as ideal tracers to track water through
the soil and to separate evaporation from transpiration. Due to the technical developments in …

Climate, physical landscapes, and biota interact to generate heterogeneous hydrologic
conditions in space and over time, which are reflected in spatial patterns of species …

Current land surface models assume that groundwater, streamflow and plant transpiration
are all sourced and mediated by the same well mixed water reservoir—the soil. However …

Plant root water uptake (RWU) has been documented for the past five decades from water
stable isotopic analysis. By comparing the (hydrogen or oxygen) stable isotopic …

Hydraulic redistribution (HR) is the passive movement of water between different soil parts
via plant root systems, driven by water potential gradients in the soil–plant interface. New …

Abstract Background In the Mediterranean climate, plants have evolved under conditions of
low soil-water and nutrient availabilities and have acquired a series of adaptive traits that, in …

Hydraulic redistribution (HR)–the movement of water from moist to dry soil through plant
roots–occurs worldwide within a range of different ecosystems and plant species. The …

In the Mediterranean evergreen oak woodlands of southern Portugal, the main tree species
are Quercus ilex ssp. rotundifolia Lam.(holm oak) and Quercus suber L.(cork oak). We …

Sudden pulse-like events of rapidly increasing CO2-efflux occur in soils under seasonally
dry climates in response to rewetting after drought. These occurrences, termed “Birch effect” …

Despite the intensive management practices available to modern agriculture, drought and
salinity are still major constraints on crop production and food security. Yield losses to …
