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.

For scientists like Andrew Groover, the Arnold Arboretum offers direct access to a diversity of living plants, associated data, and laboratory resources that otherwise would be daunting to find in one location.
The process of whole-genome duplication, or polyploidy, plays an important role in the formation of new species. Franchesco Molina‐Henao and Robin Hopkins examined this role in diploid and polyploid populations of Arabidopsis arenosa in new work published in American Journal of Botany. Abstract»
Harold Suárez-Baron, a PhD candidate at the University of Antioquia in Colombia, received a Deland Award at the Arnold Arboretum to study Dutchman's pipevines (Aristolochia), particularly their unusual mechanism for attracting and retaining flies for pollination.
Understanding the role of different cues, like temperature and chilling, is important to predict how plant phenology, or the timing of life cycle events, will respond to climate change. Published in New Phytologist, Dan Flynn and Elizabeth (Lizzie) Wolkovich manipulated various cues using a growth chamber to understand this complex process. Abstract»
While floral diversity has been studied extensively in animal-pollinated plants, much less is understood about why wind-pollinated plants also exhibit diversity in reproductive structures. Published in Annals of Botany, Juan Losada, Fellow of the Arnold Arboretum, and Andrew Leslie, Assistant Professor at Brown University examined this diversity in conifers. Abstract »
Dr. Marjorie Lundgren, a postdoctoral research associate at MIT and visiting fellow of the Arnold Arboretum, won a British Ecological Society Small Research Grant for a project exploring perenniality in Brachypodium grasses, in collaboration with Professors David Des Marais of MIT and Barry Logan of Bowdoin College. Congratulations Marjorie!
Robin Hopkins was awarded the Harvard Fannie Cox Prize for Excellence in Science Teaching. This awards recognizes Robin's dedication to teaching complex concepts in life sciences while inspiring her students to pursue science careers. Congratulations Robin!
