15 October 2017: All members of the Baumann lab – Hannes, Emma, Chris, Julie and Jake had fun at an Open House event at the Avery Point Campus as part of the 50th Anniversary celebrations. The whole department participated with a flurry of educational activities and fun exhibitions.
Our lab manned a table outside the Rankin Lab, telling people about the nearshore fish community, the phenomenon of ocean acidification and the measurement of pH in water. Everybody chipped in, thanks!
Hannes also premiered reciting Dr. Seuss’ “The Lorax” in front of young and old in the AP auditorium.
Check out some of the fun around the “Ocean Acidification and our fish” table:
On 19-21 September 2017, Chris Murray and Hannes Baumann traveled to Fort Lauderdale, Florida, to attend the ICES (International Council for the Exploration of the Sea) Annual Science Conference in order to present our ongoing NSF and NOAA funded research on potential ocean acidification effects in Atlantic Silversides and Norther Sand lance. Due to Hurricane Irma, which had impacted all of Florida just a week earlier, it was a great relief that the conference could actually be successfully held.
From 11-16 July, Hannes, Chris, Jake (Baumann lab, UConn) and Teresa (Nye lab, Stony Brook) were presenting research from our common NSF project at the 41st Larval Fish Conference, organized by the Early Life History Section of the American Fisheries Society in Austin, TX.
Holding the fort and maintaining experiments at Avery Point were James, Julie, and Elle. Thank you for helping out.
We gave four talks in two sessions:
Baumann H., Snyder, J.T., and Murray, C.S. 2017. Quantifying offspring CO2-sensitivity in a fish: a meta-analysis.
Snyder, J.T., Murray, C.S., and Baumann H. 2017.
Potential for maternal effects on offspring CO2 sensitivity in a coastal marine fish
Murray, C.S., Snyder, J.T., and Baumann H. 2017. A multi-factorial evaluation of temperature-dependent CO2-effects in a coastal forage fish.

Here is how Jake rates his first international conference experience:
Austin Texas, July 2017. “Attending the Joint Meeting of Ichthyologists and Herpetologists was my first visit to Austin Texas and my first large-conference presentation. My presentation was part of the Larval Fish Conference, a sub-section of the larger meeting, and I quickly learned how welcoming the larval fish group of researchers, scientists, professionals, and students were. Having not been to a “destination” conference like this before, I had little expectations, but I had a lot of fun networking, discussing research, and socializing. I think the coolest non-conference related event was seeing the Mexican Free-Tailed bats that live in the Congress Street Bridge, as every night around sunset they leave to go feed. Seeing hundreds of thousands of bats stream out of the bridge was incredible, and something I’d highly recommend. The city of Austin was great, and I spent much of the first day (pre-conference) exploring the city in the scorching heat. Overall the Baumann Lab had an excellent time at the conference, and can’t wait for the next one!”
This small conference brought together approximately 150 international scientists to talk about larval fish growth, survival, maternal effects, dispersal, systematics to name just a few. It was held in special honor of Edward Houde, who over his long career has inspired generations of marine scientists.
While Chris was presenting last years data about growth consequences of high CO2 exposure across life stages in our model species, the Atlantic Silverside, Hannes participated in the Early Career workshop and gave a talk about how to approach the writing of a scientific manuscript (PDF).
On 12 May 2016, the Department of Marine Science hosted it’s 11th Biennial Feng Graduate Research Colloquium, during which graduate students of the department traditionally present findings of their thesis research and/or give a preview of their future plans.
This year, Chris presented the results of last years study on long-term changes in growth distributions in Atlantic silversides exposed to high CO2 conditions, whereas Jake presented a poster outlining his thesis research on long-term environmental and biological data collected by Project Oceanology.
On 15 March, Hannes gave a lecture at Mitchell College in New London, talking about the combined effects of ocean warming, acidification, and hypoxia on marine organisms. The entire lecture is publicly available at Limnology & Oceanography e-lectures.
“It was such a pleasure to have you present to the class today; your lecture was excellent – engaging with just the right amount and level of information. I’m glad that you intend to continue to provide outreach/education to the community on this topic.”
On 26 February 2016, H. Baumann was invited to give a seminar at the Biological & Environmental Sciences Colloquium Series at the University of Rhode Island, featuring the recently published e-lecture on “Combined effects of ocean acidification, warming, and deoxygenation on marine organisms”
His host, David Bengston has been a renowned fisheries and aquaculture biologist for the past 40 years.
A suite of parallel anthropogenic changes affects contemporary marine ecosystems. Excessive carbon dioxide (CO2) pollution results in warmer, more acidic oceans with lower dissolved oxygen (DO) levels, meanwhile the emission of reactive nitrogen/phosphorus results in eutrophication, excessive microbial degradation and thus metabolic hypoxia and acidification. Despite decades of empirical research how each individual stressor of the ‘climate-change syndrome’ (i.e., temperature, CO2, DO) affects the fitness of marine organisms, we still know little about the combined effects of these stressors. This lecture gives an overview over the nascent field of multi-stressor approaches evaluating the climate sensitivity of marine organisms across taxa. In most studied cases, combined effects of these stressors exceeded those observed individually. Effects of combined warming, acidification, and deoxygenation have mostly been additive (no stressor interaction) or synergistically negative (stressor interaction). The occurrence and strength of synergistic stressor interactions in some species, life history stages, and traits comprises a vexing challenge but hints at potentially greater sensitivities of organisms to marine climate change than previously recognized. This lecture is intended for post-secondary students, providing them with illustrated examples from the most resent literature, while aiding in communicating the urgent need for empirical data from multi-stressor approaches.

“I had no idea that ‘Graphical recording’ was a thing.
But Tracey Berglund, an artist currently living in NYC achieved with a whiteboard an a bunch of colored markers, what I wouldn’t have thought possible: a visually entertaining and remarkably accurate depiction of the main points of my talk, which highlighted the multistressor reality of climate change and the need for according experimental approaches.”
