  abstract = {{I}ncreases in drought-induced tree mortality are being observed in tropical rain forests worldwide and are also likely to affect the geographical distribution of tropical vegetation. {H}owever, the mechanisms underlying the drought vulnerability and environmental distribution of tropical species have been little studied. {W}e measured vulnerability to xylem embolism ({P}-50) of 13 woody species endemic to {N}ew {C}aledonia and with different xylem conduit morphologies. {W}e examined the relation between {P}-50, along with other leaf and xylem functional traits, and a range of habitat variables. {S}elected species had {P}-50 values ranging between -4.03 and -2.00{MP}a with most species falling in a narrow range of resistance to embolism above -2.7{MP}a. {E}mbolism vulnerability was significantly correlated with elevation, mean annual temperature and percentage of species occurrences located in rain forest habitats. {X}ylem conduit type did not explain variation in {P}-50. {C}ommonly used functional traits such as wood density and leaf traits were not related to embolism vulnerability. {X}ylem embolism vulnerability stands out among other commonly used functional traits as a major driver of species environmental distribution. {D}rought-induced xylem embolism vulnerability behaves as a physiological trait closely associated with the habitat occupation of rain forest woody species.},
