As a center for plant science, the Arnold Arboretum contributes to the study of our changing planet. At Weld Hill, state-of-the-art laboratories and tools enable researchers to investigate how plants will respond to changes like higher concentrations of carbon in the atmosphere. An ongoing project with Boston University collects data on nitrogen and other atmospheric […]
One of the joys of living in the temperate world is to experience the days lengthening in spring, the temperatures increasing, and our woody vegetation waking up in response. After a long hiatus, we suddenly see trees flushing flowers and leaves and we realize that their development has silently snuck up on us. These noiseless […]
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»
Most wine is produced from the same 12 varieties of grapes, a huge concern for growers in the face of climate change. Elizabeth Wolkovich, Ignacio Morales-Castilla, and colleagues have published research suggesting the other ~1100 varieties of grapes and the diversity of their attributes may play an important role in the future of the wine industry.

The Tree Spotters monitor the life cycles of trees, noting when they bud, grow leaves and turn colors. The data they collect is used by scientists to study everything from seasonal allergies to how climate change may be affecting New England’s trees. Read more from WGBH.
Each year we witness the seasonal schedules of plants—when they flower, fruit, and unfurl and drop their leaves—in our gardens, parks, and wild areas. The details of these schedules are vitally important to pollinators, herbivores, and frugivores, and to horticulturists, farmers, landscape architects, and ecologists. Even so, we know surprisingly little about the phenology (or […]
The USA National Phenology Network’s most recent Annual Report includes a full page feature on the Arnold Arboretum Tree Spotters—a volunteer citizen science program dedicated to collecting phenological data to aid scientists studying climate change. Check out the feature on page 6.
Published in Journal of Ecology, Elizabeth Wolkovich and colleagues review how natural phenological diversity present in different wine varieties may positively impact the response to a changing climate. abstract »
With the eye, the drone and the satellite, researchers, Margaret Kosmala, David Basler (Sinnott and Sargent Awardees), Richard Primack and Eli Melaas (Boston University) are looking closely at individual trees to track changes in phenology (life events like leafing out) due to climate change.
