Limnology Seminar Series

Everyone is Welcome

The Queen's Department of Biology's Limnology Seminar Series is held weekly during the academic year (as well as special sessions during the summer) to explore topics related to limnology, paleoecology, and aquatic science.  All seminars are held in the EEB seminar room beside the lunchroom on the 4th floor of the Biosciences Complex (Rm. 4338), Wednesdays at 12:30 PM. The current but evolving schedule is given below.  Watch for updates.

Presenters will have the opportunity to meet with limnologists in the department (graduate students and professors) and can be provided with temporary workspace and internet access.  The seminar coordinator will set up the room prior to each seminar.  The department will provide audiovisual equipment and a laptop computer.     

To be added to the e-mail distribution list, or to enquire about presenting a seminar, please contact the coordinator Emily Stewart ( Thank you for participating!!
