I was out at Harvard Forest last week and got stuck in a traffic jam behind two moose on Pierce Road. I also managed to corner this little centipede in one of my tubes in the heated + N addition plots.
Spring break! I was out in the peaceful snowy forest taking an early round of root photos and respiration measurements. Did a bit of snowshoeing up around my plots . It was bright and beautiful – I think I even got a bit of a tan! What more can you ask?
I’ll be showing a poster at the HF Ecology Symposium comparing the root phenology of hemlock and oak stands – and moderating a lunch for graduate students.
We installed minirhizotron tubes into the long term soil warming + N addition plots at Harvard Forest to look at the impacts of temperature and nutrient addition on root dynamics. Here are some highlights:
Including these plots, we have a total of 59 tubes at Harvard Forest. Special thanks to everyone who helped to install: Marc-Andre Giasson, Allison Gill, Pat Sorensen, Andy Reinmann, Xi Yang, Tim Savas, and Mel Knorr.
Here are some photos of Sam working with the camera and a wonderful zoom shot of mycorrhizal hyphae colonizing a root tip. I’ve taken some of our preliminary findings to ESA in Portland, OR and will be presenting a poster at the LTER All Scientist’s Meeting in Estes Park, CO.
Starting my first season as a mentor for the Harvard Forest REU program, working with Sam Knapp, from the University of Wisconsin. He is spending considerable time in the forest with our minirhizotron camera, and being supremely helpful during my other sampling campaigns. Recently, root exudates:
As the school year wraps up, so does my teaching experience with the NSF GK12 fellowship program. For lesson plans and highlights of my year spent in a 5th grade science classroom, please visit my GK12 GLACIER site.
