英文摘要	Background: Phenotypic and functional traits of plant populations vary with environmental conditions at local and regional scales. The analysis of these traits along environmental gradients provides information on the differential response of populations to climate changes. Objective: We analyzed the leaf morphological variation of an endemic oak to identify the degree of population differentiation along an environ-mental gradient. Study species: Quercus mexicana Bonpl. (Fagaceae). Study site and dates: Samples were collected from 39 populations in the Sierra Madre Oriental and east of the Trans-Mexican Volcanic Belt from 2014 to 2016. Methods: We measured eight macromorphological traits in 5,507 leaves and three micromorphological traits in 228 leaves. We performed univari-ate and multivariate statistical analyses to assess the morphological differentiation among populations, and the relationship between variation in leaf traits and environmental variables related to temperature and water availability. Results: Populations of Q. mexicana showed leaf morphological differentiation along its distribution. Significant linear correlations were found between leaf traits and environmental variables. Smaller and thicker leaves with lower density of trichomes and smaller stomata were found in populations located in more arid regions. In contrast, larger and thinner leaves with higher trichome density and larger stomata occurred in more humid places. Conclusions: Populations of Q. mexicana are adapted to a wide range of climatic conditions. Considering the predictive future climatic changes for the region (i.e., warmer and drier conditions), Q. mexicana populations with traits better adapted to a more humid and cooler environments could be negatively affected.
