  abstract = {{S}oil nutrients and water availability are strong drivers of tropical tree species distribution across scales. {H}owever, the physiological mechanisms underlying environmental filtering along these gradients remain incompletely understood. {P}revious studies mostly focused on univariate variation in structural traits, but a more integrative approach combining multiple physiological traits is needed to fully portray species functional strategies. {W}e measured nine leaf functional traits related to trees' resource capture and hydraulic strategies for 552 individuals belonging to 21 tropical tree species across an environmental gradient in {A}mazonian forests. {O}ur sampling included generalist and specialist species from terra firme ({TF}) and seasonally flooded ({SF}) forests. {W}e tested the influence of the topographic wetness index, a proxy for soil moisture and nutrient gradients, on each trait separately and on the trait integration through multivariate indices computed from the eigenvalues of a principal component analysis on the traits of the species. {F}inally, we evaluated intraspecific trait variability ({ITV}) for generalists and specialists by calculating the coefficient of variation for each trait. {R}esults showed that (1) the environment had a greater influence on trait syndromes than single trait variation. {M}oreover, (2) {SF} specialist species expressed a stronger leaf trait coordination than {TF} specialist species. {F}urthermore, (3) the ability of generalist species to occupy a broader range of environments was not reflected by a larger {ITV} than specialist species but by the capacity to change trait coordination across environments. {O}ur work highlights the need to investigate functional strategies as multidimensional syndromes in physiological trait space to fully understand and predict species distribution along environmental gradients.},
