• Collaborator Toby Ault visited from Cornell and gave a brown-bag seminar titled “Atmospheric Perspectives on Spring Onset”.
  • Koen’s “Virtual Forest” project was highlighted in an MIT Technology Review article .
  • Bijan Seyednasrollah, a PhD student with Jim Clark at Duke, will be joining the lab as a PhenoCam project postdoc starting in May. Welcome, Bijan!
  • Barry Logan, Bowdoin College, and a collaborator on the Niwot Ridge project coordinated by Dave Bowling (Utah), visited and presented his work on leaf pigments and photoprotection in the HUH seminar. Barry’s superb talk was followed by the usual Café Sushi lunch – yum!
  • Andrew, Tim and David visited Harvard Forest to scout the location for the experimental component of the new tree growth study. Tim and David are shown in front of what will be Tim’s “summer home” at the Forest.
  • We kicked off the month with Lab Happy Hour on February 1.


  • The proposal submitted to the NERC-NSF “international collaboration” program by Andrew R. and Andrew Friend (Cambridge), “Addressing carbon source and sink controls on tree growth”, has been recommended for funding. The project will support modeling, observational field studies, and an experimental manipulation at Harvard Forest. Tim and Andrew R. will be leading the Harvard activities, with David and Mariah also participating.
  • A report on the phenology workshop that Andrew organized (with Jake Weltzin, USA-National Phenology Network, and Jeff Morisette, USGS) at Harvard last spring, has been published in Eos . The report highlights the potential for coupling real-time phenological monitoring (as, for example, from phenocams), together with cross-scale data integration and modeling, to improve management of ecological systems in the face of increasing climate variability and change. Thanks to Jake and Jeff, as well as all workshop participants, for their contributions!
  • Meghan travelled to Corvallis and Clatskanie, Oregon, to collect samples for her research on NSC storage in Populus trichocarpa. Despite record lows and snow storms, she was able to collect over 500 root, 400 stem, and 600 branch woody tissue samples and ship them back to Cambridge for processing. There’s a lot of lab work to be done now!
  • Tim Rademacher (PhD Cambridge) has joined the lab as a postdoctoral researcher. Tim will be working on carbon allocation modeling. Welcome Tim!
  • The Bartlett Experimental Forest tower is now in its fourteenth year of making eddy covariance measurements. Wow! Related to this, the NEON top-of-tower phenology camera at Bartlett is now streaming imagery; the solar panels on our skinny Rohn 25G tower can just be seen on the left hand side of the image.
  • The journal article “Volunteer recruitment and retention in online citizen science projects using marketing strategies: lessons from Season Spotter,” written by collaborator Alycia Crall at NEON, was published in the Journal of Science Communication. Coauthors include Margaret and Andrew.
  • Happy New Year!
