Meets Thursdays, 2:30-3:30 PM, Starr 2nd floor classroom, unless otherwise stated.

MBL Micro-Eco Discussion Group, Spring 2012


January 26 -- Joe Vallino

Joe will present some results from the microcosm experiment he, Julie Huber, and Nuria Fernandez Gonzalez have been conducting. He suggests that ahead of time, you could go to the project web site and poke around to get oriented:   http://ecosystems.mbl.edu/MEP/

For example you can see data here:  http://ecosystems.mbl.edu/MEP/Experimental/ATBexp1/ATBexp1.html
