Fish & Genes - Spring 2022

We hold a weekly Zoom meeting to talk about recently published articles that are relevant to the lab's interests. The subjects are heavily biased towards fish, fish evolution and molecular genetics. This page lists the reading schedule for the Spring 2022 iteration of the journal club, which will begin meeting Fridays at 10 am (Alaska time ) starting January 14.

March 25 - Change of plans! Graduate students from the Alaska Chapter of the American Fisheries Society are holding their annual symposium on this date. Two of our team (Habiba Moshfeka and Maggie Harings) are presenting. So, we will not hold journal club meeting and push the Atlantic cod discussion to next week.
