Adaptation strategies of coastal fishing communities as species shift poleward published in ICES Journal of Marine Science

Dr. Talia Young and co-authors found substantial community-level changes in fishing patterns since 1996. Southern trawl fleets of larger vessels with low catch diversity fished up to 400 km further north , while trawl fleets of smaller vessels with low catch diversity shrank or disappeared from the data set over time. Trawl fleets (regardless of size) with high catch diversity, however, did not dramatically change fishing location, nor disappear from the data set as often. Their analysis suggests that catch diversity and high mobility could be effective adaptation strategies to environmental change.

Fishbowl Chat #1

As part of the openscapes initiative, the Pinsky Lab met this week to discuss better data science, starting with getting everyone in the lab connected to our
GitHub organization.

We began by explaining the difference between git and GitHub and then had a 20 minute group discussion about what we should be putting on GitHub and how we wanted to use it as a group tool.

We spent the rest of the hour in breakout groups addressing different obstacles people faced as beginner GitHub users. One group was creating accounts, one group was connecting to the pinskylab organization, and another was connecting RStudio to GitHub.

It was great to see people migrating from group to group as issues were solved. By the end of our time together, it seemed like everyone had a good handle on using GitHub to share work with the rest of the team.

This open communication has leaked into the general discussion going on in our open work space. Lab members seem more comfortable with asking teammates for help, and it is exciting to see all of us getting on the same page with our data science.

American Lobster Density from OceanAdapt featured in Washington Post Article

Maps of the distribution density of American Lobster (Homarus americanus) through time from OceanAdapt featured in Zoeann Murphy and Chris Mooney’s article in the Washington Post

Pinsky lab data on the distribution density of the American Lobster were featured in Zoeann Murphy and Chris Mooney’s article, “Gone in a Generation: Across America, climate change is already disrupting lives”, published in the Washington Post. The interactive article details the impact of climate change on forests and fisheries, and the magnitude of floods and fires across the U.S., in several visually stunning and compelling stories.

These data, as well as data on many marine fish and invertebrate distributions around the United States are available on our OceanAdapt website.

Becca Speaks About Warming Oceans on New Orleans Public Radio

Dr. Becca Selden spoke with WWNO’s Travis Lux on ocean warming and its impact on marine life and fisheries. The conversation is in response to Cheng et al.’s recent article in Science, which suggests that oceans are warming faster than previously predicted, and Morley et al. 2018, which predicts marine species range shifts around North America.

Congratulations to Dr. Becca Selden, New Faculty at Wellesley College!

Becca will be joining the faculty as an assistant professor of marine biology at Wellesley College, a premier liberal arts college in Massachusetts, in September. Wellesley has a strong commitment to undergraduate research, and she hopes to launch the careers of the next generation of women scientists. Her research program will investigate the cumulative impacts of harvest, climate change, and species invasion on marine ecosystems, utilizing the Gulf of Maine as a key local study system in addition to her regional and global efforts using quantitative tools. She looks forward to continuing her collaborative work with NOAA colleagues at NEFSC, and intends to engage with policymakers on issues of conservation and fisheries management relevant to Northeast coastal ecosystems.

Congratulations, Becca!

Alternative stable states in conservation behavior in PNAS

Ed Tekwa (postdoc in the lab) led a study just out in PNAS, “Path-dependent institutions drive alternative stable states in conservation.”

We hear almost every day in the news about environmental disasters, but the world is also full of many environmental success stories. Why do we succeed at conservation some of the time, but fail other times? In our paper, we studied people’s decisions about whether to conserve or to over-harvest a renewable resource like fish or timber. Surprisingly, we found that people often get trapped by their past decisions. If they start out over-harvesting, they tend to continue over-harvesting. But the opposite is also true: once people start conserving, this behavior is also self-perpetuating. We built a mathematical model for this behavior, and showed that it explains global patterns in fisheries decisions better than any previous theory.  Our results challenge the conventional expectation that collapse of fast-growing resources is unlikely, but also offer hope that conservation is much easier to continue once we start.


Welcome to Jude Kong!

We’re excited to welcome Dr. Jude Kong to the lab! Jude brings a wealth of experience in mathematical modeling and applied math, including for diseases and aquatic ecosystems. He has his PhD from U. Alberta and will be working on process-based models for shifting species distributions. Welcome, Jude!

August 2018 Conferences!

Several lab members went off to scientific conferences this month to give talks, present posters, and meet others in the field! Becca, Allison, and Mike attended the American Fisheries Society’s annual meeting in Atlantic City,  Allison and Lisa went to New Orleans to attend the Ecological Society of America’s annual meeting, and Jennifer took off to Montpellier, France for the 2018 Joint Congress on Evolutionary Biology.


  
    

 

Jennifer’s paper published in Evolutionary Applications!

Jennifer and Malin’s paper, Genomic signatures of environmental selection despite near‐panmixia in summer flounder, was released for early-view in Evolutionary Applications. The paper describes how summer flounder are a single population based on many genetic markers, yet the frequency of some genetic markers are associated with their environment, particularly bottom temperature. This suggests that although summer flounder are capable of high dispersal and lots of genetic mixing, spatially variable environmental selection is likely resulting in adaptation to local environmental conditions.
