- Trevor, Andrew and Mariah began collecting samples for the Milton Fund project on nonstructural carbohydrates in red maple trees. Mariah is shown collecting stump sprouts from a recently-harvested stand in the White Mountains National Forest over Memorial Day weekend. The bugs were out!
- Andrew's recent proposal to NSF's Macrosystems Biology program, "Continental-Scale Monitoring, Modeling and Forecasting of Phenological Responses to Climate Change", was approved for funding. Co-PIs are Mark Friedl (Boston University), Steve Frolking (University of New Hampshire), and Robert Pless (Washington University, St Louis).
