2022 Winter Biology Virtual Symposium

June 6-8 2022

Winter can be the defining season for biology in habitats that typically experience snow and ice. In this virtual symposium, we will bring together winter researchers from a range of disciplines to continue fostering an international Winter Biology community.

Our speakers are derived from the defunct Gordon conference, but we will ensure opportunity for interaction for the whole community. We welcome researchers at all stages of their scientific career to this no-cost symposium.

The meeting was a huge success. Recordings of the talks will be available on a private link on YouTube until the end of July 2022. Email Brent Sinclair if you would like to receive a link to those recordings, and/or if you woudl like to be added to the email list to stay informed about future winter biology initiatives.

Note that by attending the symposium, you agree to the code of conduct.

Business Meeting
(We know, nobody likes a business meeting, but this is an excellent time to engage as a community and decide: Will we have an in-person meeting in 2024? Where? Who will organize it? Should we reapply for a Gordon Conference given our 2020/2022 experiences? This is your opportunity to have a say in how the international winter biology community develops.)

The Winter Biology Virtual Symposium is organized by Sapna Sharma, Brent Sinclair, Steven Cooke, and Pamela Templer.
