Our plans to head out fishing for fluke (inspired by our fluke genetics project) were dead in the water when the party boat stayed in port for repairs. Instead, we went out fishing for bluefish. A good 4-6′ swell, but a great time on the water. Jennifer caught the first two, and Ryan caught the most (3). Turns out that the adrenaline of reeling one in is a good cure for seasickness. And they were delicious grilled that evening… More photos here.

Malin is off to the Ecological Society of America meeting in Sacramento, CA next week, in part to run a special symposium on Thursday afternoon, “Climate and Beyond: Cumulative Impacts and Species Range Shifts” with Adam Wolf and Morgan Tingley. They have a great line-up of speakers, so come check it out! Malin will be presenting some of the lab’s new work on the interaction between climate velocity, fishing, and marine protected areas.
Maybe you saw the front page of the New York Times last Tuesday? It had the image here, and it was highlighting the publication of a new report from the federal government called the National Climate Assessment. Think of it like the IPCC report, but for the U.S., and it represented the work of hundreds if not thousands of scientists synthesizing everything we know about climate and its impact on this country. It’s fantastic to see it get this attention!
We got to see one small corner of this report in the making, since Malin was on the team that wrote the 296 page “technical input” report on Biodiversity, Ecosystems, and Ecosystem Services. It was a long and deliberate process… it started with conference calls through the fall of 2011, then a meeting with dozens of experts in Palo Alto, CA to flesh out the major pieces of the report. Then writing and revising through the spring of 2012, including a special box on “Climate Impacts on New England Fisheries” that we wrote. From there, a federal committee made up of academic and government scientists synthesized all the technical input reports, plus other materials into a draft National Climate Assessment. That was posted online in January 2013 for 90 days of public comments (more than 4000 received and responded to) and extensive peer review, including from the National Academies.
And then… drumroll, the final report came out this May, 2014, all 829 pages of it (don’t be too intimidated, though: the website they put together is beautiful and accessible). Wow, that was a long process. But if it has the power and authority to affect the actions of our federal, state, and local governments, plus change public attitudes and business planning, it’s entirely worth it. Oh, and that box on New England fisheries? Find it here, in the Oceans chapter of the final National Climate Assessment.
Genetic diversity is the raw material for evolution, and it allows species to adapt to changing environmental conditions. But can fisheries cause species to lose genetic diversity? In our meta-analysis just out this week in Molecular Ecology (OnlineEarly), we find strong evidence that the answer is yes. Previously, studies on individual populations have had somewhat ambiguous results: some studies found an effect, others did not. Our finding provides more evidence that the evolutionary impacts of overharvest are important for fisheries management, and may explain why some heavily overfished populations (e.g., Newfoundland cod) have had such a hard time recovering.
Nature Climate Change ran a feature story on Mike Fogarty and Malin’s earlier paper in Climatic Change Letters. To quote the story: “Adaptation to climate change in fisheries is occurring very rapidly. Research now shows that it is a complex process whose outcomes can both mitigate and exacerbate impacts on fish populations.” How people respond and the coping responses they use are an important part of the story.
It is increasingly clear that marine fish are shifting and will continue to shift poleward as climates warm. However, what these shifts mean for fisheries has long been less clear. In a new paper in Climatic Change, Mike Fogarty and Malin show how fisheries and the value of their landed catch are also moving poleward (see graph on right for four species in the northeast U.S.). These shifts push some species out of reach for coastal communities, but also provide new opportunities. This kind of information can inform decisions about how to adapt to climate change, but such adaptations take time and have costs. Local knowledge and equipment, for example, are geared to the species that have long been present in the area.
Malin will talk about his ongoing research on climate and marine range shifts at the Ecological Society of America: August 6, 1:30pm, COS 5-1.
