Precipitation mediates sap flux sensitivity to evaporative demand in the neotropics
Original language description
Transpiration in humid tropical forests modulates the global water cycle and is a key driver of climate regulation. Yet, our understanding of how tropical trees regulate sap flux in response to climate variability remains elusive. With a progressively warming climate, atmospheric evaporative demand i.e., vapor pressure deficit (VPD) will be increasingly important for plant functioning, becoming the major control of plant water use in the twenty-first century. Using measurements in 34 tree species at seven sites across a precipitation gradient in the neotropics, we determined how the maximum sap flux velocity (v(max)) and the VPD threshold at which v(max) is reached (VPDmax) vary with precipitation regime mean annual precipitation (MAP), seasonal drought intensity (P-DRY) and two functional traits related to foliar and wood economics spectra leaf mass per area (LMA), wood specific gravity (WSG). We show that, even though v(max) is highly variable within sites, it follows a negative trend in response t
