25 February 2021. The Mid-Atlantic Ocean Acidification Network (MACAN) organized a four-part webinar series on Ocean Acidification geared specifically towards recreational anglers and shellfish collectors in the Mid-Atlantic region. The series is called “Hooked on OA” and invited Hannes on this February Thursday to explain the state of OA science particularly for fishes. A big thanks to the organizers and the more than 50 people who participated in this webinar.

23 June 2020. It’s been a remarkable day. A remarkable few months of preparation. But on this Tuesday in June, more than 250 people from all over the world logged in to a UConn WebEx Event organized by Hannes Baumann, Eric Schultz, Jacqueline Webb, Paul Anderson and Jon Hare. The event, billed as the “1st Virtual Larval Fish Science Town Hall” was of course a product of the strange and challenging times we live in right now. A consequence of almost a year of painstaking preparations for the 44th Larval Fish Conference in Mystic, CT … eclipsed by the COVID-19 pandemic that made having a physical science conference impossible.
Number of attendees per minute throughout the day. Science sessions were followed by 120-170 attendees worldwide.
The Virtual Town Hall gave 16 speakers from around the world the opportunity to communicate their science, while providing a forum for the community to interact. The Early Career Committee of the AFS Early Life History Section contributed as well, organizing a round table discussion led by Kelsey Swieca with Chris Chambers, Jackie Webb, and Peter Konstantidinis. Individual networking meetings – although hobbled initially by technology – were held after the meeting between senior and early career researchers.
And best of all – more than 40 people participated in a picture contest, contributing stunning images of larval fish or larval fish science.

25 May 2019. Hannes, Chris and Emma attended this years 43rd Annual Larval Fish Conference in Palma de Mallorca, Spain. The event was hosted by IMEDEA’s Ignacio Catalan and colleagues and was attended by more than 140 participants. As usual, the small but international make-up of the meeting and made it into a memorable event of science, networking and seed for potential future collaborations. While Chris reported on our past experiments on factorial CO2 by O2 effects on Atlantic silverside early life stages, Emma presented the latest findings on our silverside experiments using computer-controlled CO2 and O2 co-fluctuations.
Before and after the conference, there was also some time to explore the beautiful island of Mallorca with its breathtaking mountain scenery and turquoise coves.
Chris and Emma’s presented:
Murray, C.S., Cross, E.L., and Baumann H.A factorial evaluation of the combined effects of acidification and hypoxia in Atlantic silverside offspring. Talk.
Cross, E.L., Murray, C.S. and Baumann H.Diel and tidal cycles of CO2 and dissolved oxygen conditions provide physiological refuge to a coastal forage fish, Menidia menidia under acidification and hypoxia. Talk.

By Callie Concannon. On April 30th, four graduate students from the Marine Science Department traveled to UConn, Storrs to present their research at UConn’s 2nd Climate Research Symposium cohosted by the Geology and Marine Science departments. The students were Kelly McGarry (Ph.D student; top left), Halle Berger (Master’s student; top right), Sarah McCart (Master’s student; bottom left) and Alec Shub (Master’s student; bottom right). Everyone’s presentations were well received, and Sarah McCart even won the graduate student poster competition!
The event featured two keynote speakers; Professor Margaret Rubega of UConn, and Professor Tim Cronin of MIT. Professor Rubega talked about science communication and how the scientific community could better communicate their climate change research to non-scientists without using overbearing jargon and too many words. Professor Cronin gave a speech on his past research on the suppression of Arctic air formation with climate warming.

The particularly intimate format of the Gordon Research Conference was wonderfully conducive to listening to groundbreaking science in form of keynote lectures and posters and to network with colleagues from all over the world. While Hannes gave a keynote lecture about experimental progress in assessing fish sensitivity to marine climate change, Chris, Emma, Jimmy and Hans presented their research all throughout the week during the poster sessions. The beautiful setting of the conference in New Hampshire’s White Mountains and the relaxed atmosphere were all contributing to one of the most unique conference experiences all year.

The Delta Victoria Ocean Pointe Resort was the conference venueBefore the conference, we all attended a workshop on larval fish identification
Whale-watching with Corinne, Julie & Chris
Here is how Julie experienced her first LFC:
Ever since attending the American Fisheries Society conference in 2014, I’ve wanted to go to another fish-focused conference. I was lucky enough to attend the 42nd annual Larval Fish Conference this year in Victoria, British Columbia, and it surpassed all my expectations. The week started off with a larval fish identification workshop where we got to learn techniques from renowned larval fish experts (and see some really cool fish larvae!). The talks were impressive and thought-provoking, providing many new ideas for research and how to give an engaging talk. My favorite part was meeting all the larval fish ecologists whose publications I’ve been reading for my thesis. I spent most of my evenings exploring Victoria with other grad students attending the conference and left with many new friends from institutes all over the world! The trip ended with a whale watch, where we saw a pod of 5 Orcas. Overall, the Larval Fish Conference was a great experience that I hope to someday attend again!
Oral presentations:
Pringle, J. and Baumann, H. Sex-specific growth and mortality patterns in juvenile Atlantic silversides (Menidia menidia) from Connecticut waters. Talk. 42nd Larval Fish Conference, Victoria, BC, Canada 24-28 June 2018
Murray, C.S., Wiley, D., and Baumann, H. Early life stages of the northern sand lance Ammodytes dubius show high sensitivity to acidification and warming in a CO2 × temperature factorial experiment. Talk. 42nd Larval Fish Conference, Victoria, BC, Canada 24-28 June 2018
Members of the Baumann lab attended two back-to-back meetings in Portland, OR, in February. From 11-16 February, we participated in 2018 Ocean Sciences Meeting, while from 17-19 February we all took part in the 4th Ocean Acidification Principal Investigators meeting.
Holding the fort at the Rankin lab were Julie and Charles, who did an excellent job. Thank you guys!
At OSM, Hannes chaired a large session (OC51, OC52) titled “Multiple Stressors and Multiple Disciplines: Understanding the Consequences of Global Ocean Change for Marine Species” together with colleagues from Bermuda Institute of Ocean Sciences (BIOS, Amy Maas), the Virgina Institute of Marine Sciences (VIMS, Emily Rivest), and the University of South Carolina (Catherine Davis). The line-up of speakers was impressive and included our very own Emma Cross (speaking on brachiopod resistance to CO2) and Hans Dam (presenting our findings of multigenerational CO2 effects on the copepod Acartia tonsa).
Portland, albeit rainy, was as usual a great city to come to.

Ashley van Etten designed the beautiful official artwork representing this years CERF conference. Thanks Ashley for letting our lab feature your art here!
On 5-9 November 2017, the Baumann lab attended the 24th Biennial Conference of the Coastal and Estuarine Research Foundation (CERF) in Providence, RI. The conference is a unique blend of academic and conservation science and comprises an ideal venue for students to present their thesis research to a broad national and international audience. Best of all this year: the conference logo featured a beautiful piece of art depicting an underwater scene with our most beloved, famous fish, the Atlantic silverside. Big shout out to Ashley van Etten and her inspiring artwork!
Together with Steve Litvin (Monterey Bay Aquarium) Hannes convened a theme session titled “Physiological ecology in the Anthropocene: linking the laboratory and field” and talked about our recently published paper on pH and oxygen fluctuations in nearshore coastal environments. Jake presented his Master thesis research on the newly digitized long-term time series of Project Oceanology, and Julie talked about the first aspect of her ongoing research on silverside otoliths and inferred patterns of growth and temperature-dependent sex determination. Well done, all!
