I was invited to give my perspective on climate as an emerging issue for fisheries to members of Congress during a hearing on the State of Fisheries. My full written testimony and the entire hearing can be found here: https://naturalresources.house.gov/hearings/the-state-of-fisheries

We find that piscivorous fish across three large marine ecosystems (LMEs) vary widely in the degree to which their diets differ as they grow in size. The timing of diet shifts drove tradeoffs between fisheries yield and the strength of predator-prey interactions. RL Selden, RR Warner and SD Gaines (2018) Ontogenetic shifts in predator diet drive tradeoffs between fisheries yield and strength of predator-prey interactions Fisheries Research 205: 11-20 https://doi.org/10.1016/j.fishres.2018.03.021 Becca Selden teamed up with DataSpire's Kristin Hunter-Thomson to develop an educational resource with Science Friday's educational director Ariel Zych. The resource teaches 7-12th grade high school students to interpret the impacts of warming oceans on marine ecosystems.
Check it out at: https://www.sciencefriday.com/educational-resources/interpreting-the-impacts-of-rising-ocean-temperatures-on-ecosystems/ Our new research published in Global Change Biology suggests warming oceans will alter the functional role of Atlantic cod in the Northeast U.S LME, but warm-water predators like spiny dogfish may compensate. Functional diversity in temperature preferences among piscivores may buffer the impacts of warming on predator-prey interactions.
Research is featured here A two-day symposium I organized with Roger Griffis (NOAA) and Jay Peterson (NOAA) highlighted recent research on shifting species distributions and their consequences for fisheries. Presenters provided insights from a diverse array of expertise from natural science, economics, social science, and law. Abstracts for the symposium: Day 1, Day 2
The symposium was featured here Becca was invited to present her PhD and post-doctoral research in the departmental seminar series at Bowdoin College, her alma mater. She presented a talk entitled “Climate, fishing, and marine food webs: predator-prey interactions in a changing ocean.” Her research and career to date were featured on the Bowdoin website!

While vacationing in La Paz, we had the chance to snorkel with whale sharks that come into the bay in December to feed on abundant krill. I swam with this one continuously for about 5 minutes, and had the opportunity to encounter 7 others during the trip. It was an incredible experience, and one to cross off the bucket list! |
