[Lab news] Chris and Hannes attend ICES Annual Science conference

ASC 2017 poster

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 Northern 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.

Together with Chris Chambers (NOAA), Ian Bradbury (DFO, Canada), and Richard McBride (NOAA), Hannes convened a theme session titled “Patterns, sources, and consequences of intraspecific variation in responses of marine fauna to environmental stressors“.

Chris gave a talk and a poster during this session, which was well received and thus a worthwhile exposure for Chris and our lab’s research.

Here is how Jake rates his first international conference experience:

Jacob-Snyder
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!”

[Conference] Chris and Hannes present at the 40th Larval Fish Conference

CBL


The 40th Larval Fish Conference of the American Fisheries Society‘s (AFS) Early life history section (ELHS) was held from 19 – 23 June 2016 at the Chesapeake Biological Laboratory in Solomons, MD.

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).

Thanks to all the colleagues and friends for the great time and conversations. See you next year in Austin (TX)!

[Talk] Chris & Jake present at the Feng Graduate Research Colloquium


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.

In addition, Jake took his poster ‘on the road’ already and presented it at the 16th Long Island Sound Research Conference (13 May, Bridgeport, CT), while Chris will give his talk again at the 40th Larval Fish Conference in June 2016 (17-23 June, Chesapeake Biological Laboratory, Solomons MD).

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.”

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.

[Talk] Future Ocean symposium (NYC) and the graphical recording of a presentation

Sustainable Ocean Development Symposium: A Perspective from Former, Current and Future Kiel Marine Scientists | September 28-30, 2015, New York City

H. Baumann gives invited lecture “Combined effects of ocean acidification and its co- stressors on marine organisms” at Columbia University

“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.”

Head bowed, Tracey.”

[Presentation] Additive & synergistic effects of concurrent acidification and hypoxia on early life stages of three coastal forage fish

H. Baumann presented the Master thesis work of Elizabeth Depasquale about individual and concurrent effects of low pH and low oxygen conditions on larval forage fish species at two international conferences. The talk highlighted the novel findings of the study, i.e.: (1) that sensitivities to combined stressors are species- and trait-specific, (2), that larval fish overall seem to be less tolerant of low oxygen than low pH condition, but that (3) the combined effects can be additive and even synergistic; hence suggesting that focussing only on hypoxia in urbanized, eutrophied coastal waters may considerably underestimate the negative effects on larval fish. Even though hypoxia and acidification are almost always coupled conditions in marine environments, the empirical database on such multistressor experiments is still very small and thus precludes robust conclusions and generalizations across taxa or ecosystems.
