Populations from eastern Germany, northern Poland and the Czech Republic showed lower tracheary element lumen area and higher tracheary element density compared with the other populations, while xylem conductivity negatively correlated with latitude. Thickness of leaf parenchyma layers increased towards the East and, consequently, correlated with temperature indicators of climate continentality. No correlation between structural and physiological traits was observed.<br \/>\n<strong>Conclusion<\/strong> The observed trends and associations with climate indicate adaptive variation of the studied traits.<\/p>\n<p><strong>Keywords<\/strong><br \/>\n<em>Fagus sylvatica<\/em> L.; Leaf parenchyma; Leaf xylem; Vascular traits; Modulus of elasticity; Atomic force microscopy<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-020-00986-6'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nKardo\u0161ov\u00e1, M., Hus\u00e1rov\u00e1, H., Kurjak, D. et al.
