In the American Journal of Botany, Arboretum Putnam Fellow, Elizabeth Spriggs and colleagues investigated closely related species of Viburnum using sequencing and herbarium specimens. They found that flowering time differences helped maintain separation of species in populations growing in close proximity. Abstract»
In experiments conducted at the Arboretum, Elizabeth Wolkovich and colleagues showed that plant genetics can help provide more accurate predictions of when plants will break bud in spring as climate change progresses.
Each spring the Arnold Arboretum awards funding to a number of independent research projects submitted by students, post-doctoral researchers, and biological and horticultural science professionals.
A major NSF grant to enhance research, teaching, and public information on topics related to biological diversity has been awarded to Robin Hopkins .
As a Putnam Fellow, Jessica Savage focused on how the vascular system influences the timing of flowering in trees. Published in American Journal of Botany, her research shows that trees that flower before they leaf out invest more resources for flower development the previous year rather than in the spring before the vascular system is fully functional.
