	abstract = {<p>Leaf structural and photosynthetic pigment characteristics were measured in three dominant gallery-forest hardwood species in northeast Kansas, U.S.A. Leaves of Quercus macrocarpa and Q. muehlenbergii (more-xeric, shade-intolerant species) had significantly greater thickness, specific mass, stomatal densities and guard cell lengths than leaves of Celtis occidentalis (more-mesic, shade-tolerant). Except for guard cell lengths, these findings are consistent with differences between xeric and mesic species and shade-intolerant and shade-tolerant species. These gallery-forest species generally had much greater stomatal densities and/or lower guard-cell lengths compared to the same species or genera growing in more mesic forests further in the east of the U.S. Compared to C. occidentalis, the Quercus species had significantly greater total chlorophyll and carotenoids, but similar chlorophyll-a:b ratios. The chlorophyll findings contradict the established idea that shade-tolerant species have greater total chlorophyll and lower chlorophyll-a:b ratios, but may be related to exceptional site and climatic factors</p>},
