  abstract = {{S}everal monodominant rain-forest trees in {N}ew {C}aledonia have population size structures suggesting establishment following large-scale disturbance, with eventual replacement by shade-tolerant species predicted in the absence of future disturbance. {L}inks of dominance and population dynamics to leaf-level photosynthesis were investigated in seedlings of 20 tree species from these forests, grown in experimental sun and shade conditions. {I}n particular, we tested whether episodically regenerating ({ER}) species, including monodominants, have higher assimilation rates at high irradiances and lower tolerance of shade than continuously regenerating species ({CR}). {ER} species had higher maximum net assimilation rates ({A}(max-area)) in sun plants (9.6 +/- 0.4 mu mol m(-2) s(-1)) than {CR} species (6.2 +/- 0.3 mu mol m(-2) s(-1)) and high plasticity, typical of shade-intolerant species, but monodominant species did not differ from other {ER} species. {CR} species had leaf-level traits consistent with shade tolerance, including lower dark respiration rates ({R}d-area = 0.47 +/- 0.03 mu mol m(-2) s(-1); {R}d-mass = 7 +/- 1 nmol g(-1) s(-1)) than {ER} species ({R}d-area = 0.63 +/- 0.06 mu mol m(-2) s(-1); {R}d-mass = 11 +/- 2 nmol g(-1) s(-1)) in shade plants. {H}ence leaf-level assimilation traits were largely consistent with regeneration patterns, but do not explain why some shade-intolerant species can achieve monodominance.},
