On Friday Sept 12, 2008 at the Gnu's Room Dr. Moss will discuss his lab's recent work on parasitic and commensal marine microbes, their relationship to a host jellyfish like organism, the ctenophore Mnemiopsis leidyi, and will talk about the effects that changes in the global ocean seem to be having on the distribution of the ctenophore, and also the parasitic microbes.   The meeting will begin at 7 pm.
