In Global Change Biology, Cat Chamberlain, Elizabeth Wolkovich, and colleagues reviewed studies and metrics for measuring false spring and freeze damage risk, and suggest an integrated approach for modeling future outcomes. Abstract»
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.

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»
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 diversity in flower structure, color, and morphology 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 postdoctorate research associate at the Massachusetts Institute of Technology and visiting fellow of the Arnold Arboretum of Harvard University, won a British Ecological Society Small Research Grant of £4875 (about $6,525) for her project “Manipulating source-sink relationships to understand perenniality” in Brachypodium grasses, in collaboration with Professors David Des Marais of MIT and Barry Logan of Bowdoin College. Congratulations Marjorie!
