Jeewantha Bandara, a Pinsky Lab graduate student and Fulbright Scholar, attended the virtual annual meeting of the American Fisheries Society from September 14th to the 25th. He presented a poster titled “Use of Dissolved Oxygen, Salinity and Zooplankton Concentration to Determine Black Sea Bass (Centropristis striata) Habitat in North East Atlantic”. Jeewantha sought to determine which underlying environmental variables determine the distribution of Black Sea Bass. He used a two-stage GAM to explore the predictive power of a range of environmental variables on presence/absence and abundance of Black Sea Bass. He found that a model including salinity, zooplankton, and temperature best predicted the distribution of Black Sea Bass.

The Pinsky Lab is pleased to welcome two new graduate students, Jaelyn Bos & Kyra Fitz, and a new Post-doc, Brendan Reid.
Kyra is joining the lab as a 1st year Ph.D. student in the Ecology and Evolution program. She has a B.S. in Marine Biology from the University of California, Santa Cruz. She has studied the impacts of environmental change on a variety of species including corals, elephant seals, sea lions, sea turtles, and larval fish. Her research interests include population genomics, marine conservation biology, and spatial ecology. In her free time she enjoys playing tennis, swimming, cooking, and taking her dog, Lucy, to parks.
Jaelyn is also joining the lab as a Ph.D. student in the Ecology and Evolution program. She is from Maryland, and graduated from University of Maryland, Baltimore County in 2017 with bachelors’ degrees in environmental science and biology. From 2017 to 2019, she served with the Peace Corps in Mozambique, teaching high school biology. She’s interested in coral reefs, conservation, and ecosystem resilience, particularly in East Africa. She also enjoys hiking, running, and hanging out with friends and family (from a distance).
Brendan grew up in New Jersey and is happy to be back working for the Garden State! He received his Masters from Columbia University and his PhD from the University of Wisconsin-Madison, and post-PhD he has worked at the American Museum of Natural History and at Michigan State’s Kellogg Biological Station. He is interested in gene flow and the demographics of species and communities, and his past work has used genetics to understand these processes in a wide variety of taxa (crustaceans, sloths, marine and freshwater turtles, and fish). Brendan currently lives with his girlfriend and two cats in New York City and he enjoys hiking, reading, and music.
Former Pinsky Lab Post-doc, Dr. Jim Morley, collaborator, Dr. Thomas Fro¨licher, and Dr. Malin Pinsky assessed and quantified the uncertainty in climate impact projections in their new paper out in ICES Journal of Marine Science. Using a case study approach, the team conducted 8964 unique projections for shifts in suitable habitat of seven important marine species occurring on the North American continental shelf, including American Lobster, Pacific Halibut, Pacific Ocean Perch, and Summer Flounder. They found that projection uncertainty arose from Earth system models (ESMs), and the niche modelling approach used to represent species distributions for all species, but variation associated with the parameter values in niche models was insignificant. Greenhouse gas emissions scenario contributed to uncertainty for projections at the century scale. The characteristics of projection uncertainty differed among species and also varied spatially, which underscores the need for improved multi-model approaches with a suite of ESMs and niche models forming the basis for uncertainty around projected impacts. Ensemble projections show the potential for major shifts in future distributions. Therefore, rigorous future projections are important for informing climate adaptation efforts.

Dr. Jennifer Hoey successfully defended her PhD dissertation, “Adaptation and evolutionary potential in light of anthropogenic stressors in the ocean” on May 11th, 2020! It was by videoconference, with audience members calling in from literally all over the world. Jennifer’s research on evolutionary patterns in summer flounder has already been published in two papers, Hoey et al. 2018 Evolutionary Applications and Hoey et al. 2020 Molecular Ecology, with a third on the way. Jennifer has also done incredible science outreach work as part of the Science Partnership Committee within the National Network for Ocean and Climate Change Interpretation (NNOCCI). She has become a vital part of not only our lab, but the entire Rutgers Ecology & Evolution community through her work with the graduate program, outdoor activities, dining, art and more. She will be sorely missed as she moves on to a postdoc at UC Santa Cruz. The biggest congratulations and thank you to Jennifer on behalf of the entire Pinsky lab and DEENR!
Jennifer Hoey, a Pinsky Lab PhD candidate, and a team of collaborators published a paper exploring larval flounder dispersal last week in Molecular Ecology. They used both SNP genotypes and otolith core microchemistry from 411 archived summer flounder (Paralichthys dentatus) samples collected between 1989 and 2012 at five locations along the U.S. east coast to reconstruct dispersal patterns over time. While neither genotypes nor otolith microchemistry alone were sufficient to identify the source of larval fish, they used otolith microchemistry to identify clusters of larvae that originated in the same location, which allowed them to make genetic assignments of clusters with more confidence. They found that most larvae likely originated near Cape Hatteras, a biogeographic break, and that larvae were transported both north and south of the break. Larval sources did not move north over time, despite the northward shift of adult populations over the same time period. Their novel, multi-tag approach, demonstrates that summer flounder dispersal is widespread throughout their range, on both intra‐ and inter‐generational timescales, and may be a particularly important process for synchronizing population dynamics and maintaining genetic diversity during an era of rapid environmental change. Broadly, their results reveal the value of archived collections and of combining multiple natural tags to understand the magnitude and directionality of dispersal in species with extensive gene flow.
An undergraduate researcher in the Pinsky Lab, Hailey Conrad, won Rutger’s Department of Marine and Coastal Sciences’ 2019 Outstanding Senior Award for her academic achievement. Congratulations, Hailey!
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 scientist on a 4-month project modeling the future of coral reefs and the potential for evolutionary rescue.
This is a temporary, hourly position starting in March 2020 at an hourly rate of $32-$60 (depending on qualifications).
The scientist will assist the PI, a postdoc, and our collaborators by performing statistical analyses and developing visualizations of outputs from a regional model of coral adaptation in the Caribbean. These analyses will contribute to our understanding of coral adaptation and the potential for conservation over the coming centuries across a realistically complex landscape. We seek to test a set strategies for expanding existing marine protected area networks in the region with the goal of facilitating coral adaptive potential. The scientist will also synthesize existing region-specific data on coral reefs and format model data for conservation applications. The work will support scientific publications, other reports, and on-the-ground conservation planning efforts.
The scientist 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, The Nature Conservancy, 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.

A new paper published in Nature Climate Change by Dr. Michael Burrows et al., with contributions from Dr. Ryan Batt (former Pinsky Lab postdoc) and Dr. Malin Pinsky, used 29 years of fish and plankton survey data to assess how warming is changing marine communities’ composition and structure. They found that “warm-water species are rapidly increasing and cold-water species are decreasing” as ocean waters warm. Informed by species’ incidence, and changes in sea surface temperature (SST), the team created measures of species’ thermal affinities, community composition, and other summary metrics. They used these to measure community-level change in thermal affinity and composition.
Regions with relatively stable temperatures (e.g. the Northeast Pacific and Gulf of Mexico) showed little change in structure, while areas that warmed (e.g. the North Atlantic) shifted strongly towards warm-water species dominance. They also found that communities whose species pools had diverse thermal affinities and a narrower range of thermal tolerance showed greater sensitivity to change.
Next, they found that communities in regions with strong temperature depth gradients changed less than expected. In these regions, rather than moving horizontally through the water, species can instead move deeper to maintain their preferred temperature.
They concluded that this evidence strongly supports temperature as a fundamental driver of change in marine systems, and that metrics based on species’ thermal affinities are useful tools to predict and provide prognoses for community dominance shifts.
