Chase Mason was awarded an Arnold Arboretum Putnam Fellowship. Chase received his PhD in 2015 from the University of Georgia. At the Arboretum, Chase will study the evolution of leaf physical and chemical defenses in relation to the leaf economics spectrum (LES), habit, and species’ source climate across 16 woody genera. LES relates the initial investment of carbon during leaf development with the net carbon gain of that leaf. Plants employ various LES strategies which impacts their adaptability to environmental conditions and stresses. Congratulations Chase!
