Understanding anatomical plasticity of Argan wood features at local geographical scale in ecological and archaeobotanical perspectives

Abstract The emergence of the Argan tree as an agricultural, pastoral, cultural, economic and ecological keystone species in Southern Morocco is considered to be linked to the settlement of agropastoral communities that favored its expansion. Nevertheless, the use and exploitation of Argan tree is d...
