Callie-Climate-Change-conference1 — Callie presenting her poster to other graduate students

November 8, 2019. Callie Concannon joined other graduate students of the Department of Marine Sciences to present her thesis research at the Graduate Climate Conference in Woods Hole, MA. She presented a poster entitled “Long-term CO₂ and temperature effects on fecundity and oocyte recruitment in the Atlantic silverside”
Her preliminary findings can be summarized as:

Warmer, more acidic environments impact reproductive output in the Atlantic silverside

[Lab news] Whole life cycle CO2 fish are getting sampled

Posted on April 24, 2019April 24, 2019 by Hannes Baumann

18 April 2019. This Thursday was a long day in the Baumann lab, because we sampled and processed over 200 adult silversides from a unique experiment. These fish were fertilized in the lab and reared from eggs to adulthood under different temperatures and contrasting CO2 conditions. We are interested to see, if future ocean conditions have measurable effects on this species fecundity, growth, and oocyte characteristics. We also took tissue and genetic samples, with an effective line-up of hands, i.e., Hannes, Emma, Chris, Callie and Lucas.
Good teamwork all!
