Patrick’s paper from his MS is now online early at Ecography! He studied temporal change in community composition across the Northeast US continental shelf and found that changes through time could be explained by species associations with bottom temperature. Measured as the Community Temperature Index (CTI), composition changed by about one third of a degree (°C) for every 1 °C increase in bottom temperature on average. Species have non-linear responses to changes in temperature, however, and these nonlinearities scaled up to a nonlinear relationship between composition and temperature.
Nice interview with Becca on her research showing that warming is transforming predator-prey interactions in the Northeast US:
Lots of great presentations this month:
- Jennifer presented 25 years of changes in population genetic patterns of summer flounder at the Ecological Society of America (ESA) meeting in Portland, OR
- Sarah presented on genomic evidence for evolutionary rescue in little brown bats hit by white nose syndrome, also at ESA
- Malin gave three talks: how ecology can help meet the UN sustainable development goals, how to teach about climate change (with Rebecca Jordan), and how climate change impacts in the ocean are different than those on land (all at ESA)
- Becca talked about changing predator-prey interactions as a result of warming in the Northeast US at the American Fisheries Society (AFS) meeting in Tampa, FL
- Jim presented a detailed projection of marine animal distributions in North America over the coming century (AFS)
- Allison presented some of her Ph.D. work on eco-evolutionary dynamics in salmon (AFS)
New paper just out online in Global Change Biology, led by postdoc Becca Selden: functional diversity among predatory fish helps protect ecosystems from the impacts of warming. Becca showed that warming has helped make Atlantic cod a much less important predator in the Northeast U.S., but other predators (spiny dogfish, hakes) have expanded to fill its role.
On a geeky note, what’s especially interesting is that these changes in predator-prey interactions with warming are occurring even though both predators and prey are shifting their distributions as the environment changes.
Ryan just published a paper in Ecology Letters showing that the number of species in many parts of the coastal ocean is going up, not down as many would expect. He spent the past few years trying to understand how marine biodiversity is changing, but his findings were initially so surprising that he doubted them.
Globally, biodiversity is going down. But because some species have started to live in more places, and different places, what happens globally isn’t what we see locally.
He studied decades of patterns in biodiversity around the North American coastline, and surprisingly, most of these regions show *increases* in the number of species present. At the same time, He found that organisms that were previously rare in these areas are becoming increasingly common.
The natural world is full of surprises.
Exciting news on the publication front:
- Jim’s paper on rapid responses of marine animals to winter temperature variability is now out in Global Change Biology. He found strong variation in how animals responded to a warm winter (higher or lower abundance; or shift north vs. south), but the rate and direction of response was predictable from thermal affinity.
- Ryan has been hard at work to understand long-term trends in species richness in marine ecosystems all around North America. The paper was just accepted in Ecology Letters! More on this later.
- Jordan Holtswarth was an REU student in our lab last summer, and her paper on reproduction in clownfish is now in press at Bulletin of Marine Science!
Data Science Technician
The Pinsky Lab in the Department of Ecology, Evolution, and Natural Resources is searching for an organized, enthusiastic, and skilled individual to work as a data science technician on a three-year project modeling the future of coral reefs and the potential for evolutionary rescue. The project is in collaboration with the Coral Reef Alliance, Dr. Daniel Schindler at the University of Washington, and other collaborators. The project is funded by the Gordon and Betty Moore Foundation.
The technician will assist the PI, a postdoc, and our collaborators by identifying, assembling, and synthesizing existing, region-specific data on coral reefs and their oceanography, ecological communities, population dynamics, evolutionary parameters, and climate in the Pacific and Caribbean. These data will contribute to regional and/or global models of coral adaptation and the potential for conservation over the coming centuries across realistically complex landscapes. Important questions to be studied include the relative role of ecological vs. evolutionary change in rapid coral adaptation, the interaction between oceanography and evolutionary processes, and the potential for conservation actions to facilitate rapid adaptation. Other duties will include assisting with data visualizations as well as project and lab logistics such as training students, preparing materials for grant reports and applications, maintaining a website, and organizing events.
The technician will be part of a dynamic research team with opportunities for professional development, presentations, co-authorship on scientific manuscripts, and collaboration with colleagues at Rutgers, U. Washington, the Coral Reef Alliance, and beyond. Rutgers offers many opportunities to interact with biologists, oceanographers, climate scientists, and other scholars in the School of Environmental and Biological Sciences, the Rutgers Climate Institute, the Institute for Earth, Ocean, and Atmospheric Sciences, and the many other institutions in the New York region.

Patrick Flanagan very successfully presented and defended his MS Thesis today, “Community-temperature mismatch in a benthic marine ecosystem.” He investigated whether changing temperature could be used to understand ecological community change on the northeast US continental shelf. Congratulations, Patrick! He’s graduating from the Graduate Program in Oceanography.
Jim Morley has a new paper just online early in Global Change Biology (here). Studying marine fish and invertebrates of the coast of the southeast US, he found that winter temperatures quickly and predictably affect species’ distribution and abundance in the following year. In particular, we found a greater abundance of southern, warm-water species following mild winters. We also found that these impacts cascade up to affect fisheries catches for many species. Interestingly, these responses appear in a region that has not been warming over the last couple decades, though 1-3 °C of warming is expected by the end of this century. Warmer winters likely will result in increased abundance of species with more southern affinities, such as white and pink shrimp, southern hake, and star drum.
