Hamed Yousefzadeh’s research primarily focuses on the morphological variations and ecological adaptations of tree species in the Caspian and Hyrcanian forests of Iran. 🌳 His investigations span diverse species such as Acer velutinum, Buxus hyrcana, Parrotia persica, and Castanea sativa. 🍃 He explores the impact of seed sources on leaf morphology, intrapopulation variations, and morphological plasticity in response to factors like altitude. 🏔️ Additionally, his work delves into root distribution patterns and the effects of elevational gradients on leaf and stomatal morphology. 🌿 Hamed’s research contributes to our understanding of plant ecology and adaptation in unique forest ecosystems.
