In this review, we address the relationship between stomatal behaviour, water potential
regulation and hydraulic transport in plants, focusing on the implications for the …

Vegetation and the water cycles are inherently coupled across a wide range of spatial and
temporal scales. Water availability interacts with plant ecophysiology and controls …

Climate change is expected to exacerbate drought for many plants, making drought
tolerance a key driver of species and ecosystem responses. Plant drought tolerance is …

Shifts in rainfall patterns and increasing temperatures associated with climate change are
likely to cause widespread forest decline in regions where droughts are predicted to …

We investigated the common assumption that severing stems and petioles under water
preserves the hydraulic continuity in the xylem conduits opened by the cut when the xylem is …

Forest ecosystem models based on heuristic water stress functions poorly predict tropical
forest response to drought partly because they do not capture the diversity of hydraulic traits …

Key message We review the recent findings on the influence of drought on tree mortality,
growth or ecosystem functioning in tropical rainforests. Drought plays a major role in …

During droughts, leaves are predicted to act as 'hydraulic fuses' by shedding when plants
reach critically low water potential (Ψplant), thereby slowing water loss, stabilizing Ψplant …

Globally, forests are facing an increasing risk of mass tree mortality events associated with
extreme droughts and higher temperatures. Hydraulic dysfunction is considered a key …

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 …
