Have you ever wondered how dragonflies and other insects survive the winter?

September 8, 2022 @ 7:00 pm 9:00 pm

***This will be a ZOOM ONLY presentation***


Rosemary Martin asks: Have you ever wondered how dragonflies and other insects survive the winter? What impact will climate change have on these important ecological communities? Drill through the ice with Rosemary Martin to discover the surprisingly active ecosystem that exists below the ice during the winter.  Rosemary will share some cool results from her PhD research on overwintering aquatic invertebrates as well as some under-ice video footage captured in a beaver pond in our very own Georgian Bluffs.

This is a ZOOM-only webinar. Details of how to join have sent out in an eHerald to members. The webinar will be open at 6:45pm to sort any technical difficulties.

Didn’t receive an e-herald but would still like to participate? Please contact web@owensoundfieldnaturalists.ca with “Insects” in the subject line.

Rosemary is just recovering from Covid-19.  When reviewing the demographics of our club, we felt it was best if she presents on ZOOM.

Rosemary “Rosie” Martin is a senior PhD Candidate in Ecology and Evolutionary Biology at the University of Toronto, Mississauga. Her work focuses on how aquatic insects overwinter and how the under-ice physical conditions determine who survives, who stays active, who eats whom, and how that all plays into food web and community structure in subsequent seasons. 

OSFN Indoor Meetings are normally held on the second Thursday of the month at 7:00 p.m. at the Bayshore Community Centre, 1900 3rd Ave E Owen Sound. There are no Indoor Meetings in July and August. Please see the individual event listings below for more details.

We invite speakers with a wide range of expertise from Grey/Bruce and other parts of the province. These evenings are open to the public. The auditorium is open by 6:30. The meeting gets under way at 7:00, and may include brief announcements by other organizations as well as OSFN club activities, club business, social time, nature sightings and reports.

The club also offers a full schedule of outdoor activities during the year. Through these outings, members learn more about the birds, plants, mammals and geology of this part of Ontario. We also keep a protective eye on our precious natural areas.
