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.
Talks and posters presented:
Baumann H.Using experiments to assess the sensitivity of fish to marine climate change: progress and knowledge gaps. Invited keynote talk.

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!
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
29 June 2018. A new experiment with Atlantic silversides (Menidia menidia) starts and as usual, it’s an all hand on deck operation. This time, we have Chris Tsang shadowing all of us and Emma professionally explaining the process.
31 March 2018. We’re happy to announce that Marine Biology just published our latest study examining the starvation tolerance of silverside larvae and juveniles at contrasting CO2 conditions. We compiled observations from five separate experiments spanning different years, laboratories, temperatures, life stages, and CO2 levels. Contrary to expectation, we found that starvation rates were largely independent of the CO2 environment in this fish species.
One major set of data was produced by Elle Parks as part of her Research Experience for Undergraduates (NSF-REU) in summer 2017. Well done, everybody!

Congratulations to Emma Cross to her new publication in Global Change Biology today!
Her study that was part of her PhD-research concludes that the brachiopod Calloria inconspicua, a common seafloor dwelling marine invertebrate from New Zealand, is more resilient to environmental change than expected.
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.

28 November 2017. The Journal of Experimental Marine Biology and Ecology just published the latest study by our group looking at differences in the CO2 sensitivity of Atlantic silverside offspring stemming from different mothers. Congratulations to Jacob Snyder for his first peer-reviewed publication.
Among the highlights of the study:
Offspring produced by different females varied in their sensitivity to high CO2 conditions.
Specific fatty acids in eggs were correlated to the log-transformed CO2 response ratio of embryo survival and hatch length.
Maternal provisioning might be an additional determinant of CO2 sensitivity in fish early life stages.
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!

October, 2nd, 2017: Happy to announce that Estuaries and Coasts just published (online) our article that looked at unifying principles of pH and DO fluctuations across many US nearshore habitats. The datasets belongs to the US Nearshore Estuaries Research Reserves System (NERRS) and is one of the most extensive monitoring datasets in coastal aquatic habitats. In this case, we used 15 years of continuous monitoring data (> 5 million data points) from 16 different reserves across the US Atlantic, Caribbean, Gulf of Mexico, and Pacific coasts and analyzed short- to long-term variability in pH and DO fluctuations. Among the highlights:
Our analyses confirmed that large, metabolically driven fluctuations of pH and DO are a unifying feature of nearshore habitats. Even more so, we were able to show that across habitats, one can predict mean pH or mean diel pH fluctuations simply based on salinity and oxygen levels/fluctuations. This provided strong empirical evidence that common metabolic principles drive diel to seasonal pH/DO variations within as well as across a diversity of estuarine environments.
As expected, there were no interannual, monotonic trends in nearshore pH conditions; instead interannual fluctuations were of similar magnitude than the pH decrease predicted for the average surface ocean over the next three centuries.
By correlating weekly anomalies of pH, oxygen, and temperature, we found strong empirical support for the notion that coastal acidification — in addition to being driven by eutrophication and atmospheric CO2 increases — is exacerbated simply by warming, likely via increasing community respiration.
