oak-trees
Oaks are a diverse genus (Quercus) of hardwood trees and shrubs in the beech family, characterized by their lobed leaves, distinctive acorn fruits, and wide distribution across the Northern Hemisphere with approximately 500 species. They represent a critical subject in plant science due to their ecological dominance in temperate and Mediterranean forest ecosystems, their complex hybridization patterns that challenge traditional species boundaries, and their long evolutionary history extending back to the Middle Eocene. Research on oaks informs our understanding of forest resilience, tree adaptation to climate change, and the genetic mechanisms underlying speciation in woody plants.
