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.

Pinsky lab PhD candidate, Katrina Catalano, won the 2019 Graduate Research Excellence Grant (GREG) – Rosemary Grant Advanced Award for her proposal, titled “An Investigation of the Effects of Genes on Larval Swimming Speed and Dispersal Distance”. This funding will allow Katrina and colleagues to perform a genome wide association study looking for associations between clownfish (Amphiprion percula) swimming endurance and genotypes. Congrats, Katrina!
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.

Changes in the total catch of a species do not always correspond to changes in total biomass or changes in the species’ distribution alone. This discrepancy drove Dr. Rebecca Selden, former Pinsky lab post-doc and current Assistant Professor at Wesleyan College, and colleagues to seek a greater understanding of the forces driving both fish stock availability and catch at US West Coast ports in their recently published article.
The team first sought to couple changes in a species’ biomass with the species’ distribution to explain the heterogeneity in stock availability experienced by fisheries across different latitudes. They measured the change in distribution and biomass of five commercial target species (dover sole, thornyheads, sablefish, lingcod, and petrale sole), and found that the timing and magnitude of stock declines and recoveries are not experienced uniformly along the coast when they coincide with shifts in species distributions.
Second, they integrated information on distances travelled by fishers with estimates of availability along the coast to generate port-specific indices of availability. They found that additional factors, like greater vessel mobility and larger areal extent of fish habitat, affect availability, and may work to counteract or augment the effects of changing fish biomass and distribution.
Lastly, they found that higher stock availability was not consistently associated with higher catch per ticket. Because fish landings were not consistently related to stock availability, Selden et al. suggest that social, economic, and regulatory factors likely constrain or facilitate the capacity for fishers to adapt to changes in fish availability.
A three-year postdoctoral position is available in the Global Change Ecology & Evolution Lab at Rutgers University. The postdoc will join a NSF PIRE-funded project to study micro-evolutionary responses to a century of habitat degradation and intensive exploitation in Southeast Asia. The project is using DNA sequencing from a unique historical collection of coastal marine fishes in the Philippines from the R/V Albatross expedition (1907-1909), complemented with modern re-collections of the same species and locations. The postdoc will join a team of researchers that includes Kent Carpenter and Dan Barshis (Old Dominion University), Chris Bird (Texas A&M), Beth Polidoro (Arizona State), Robin Waples (NOAA), Jeff Williams (Smithsonian), Angel Alcala (Silliman U.), and others.
The postdoc will lead analyses of multiple population genomic datasets through time, including changes in diversity and signatures of selection, compare impacts and changes across species, and conduct trait-based analyses to understand characteristics of populations more or less prone to genetic bottlenecks. The postdoc will also contribute to summer population genomic workshops in the Philippines. Extensive opportunities for collaboration across the multi-institutional team, across Rutgers, and in the region are available, including within the Rutgers Genome Cooperative, the Institute of Earth, Ocean, and Atmospheric Sciences, and the Genetics Department. The postdoc will have the opportunity to mentor undergraduate and graduate students.
The position is ideally suited to quantitative researchers with a strong background in population genomics, bioinformatics, data science, and global change. No experience in marine biology required, though experience with population genomic modeling, Approximate Bayesian Computation, database management, and/or hierarchical modeling is a plus. Applicants with evidence of creativity, productivity, strong oral and written communication abilities, and enthusiasm are especially encouraged to apply, particularly those that bring a new perspective, new ideas, or a new skillset to the team. A promising record of publication is valued. The successful applicant will be an independent, motivated problem solver who communicates well and enjoys working in a collaborative setting.
The postdoc start dates are flexible, with preferred dates between May and October 2020. Salary starts at $50,000 per year and includes health insurance, retirement, tax savings plans, and other benefits. Funding for conferences and a computer are available. This is a one-year appointment with the expectation that it will be renewed twice (three years total), contingent upon satisfactory performance. Applicants must have a PhD at the time of employment.
Review of applications will begin on December 16, 2019 and will continue on a rolling basis. Interested candidates should email to firstname.lastname@example.org: 1) a onepage cover letter that describes their interest in the position and their relevant background, 2) a CV, and 3) the names and contact information for three scientists familiar with their work.

Pinsky Lab members, Jennifer, Lisa, Allison, Katrina, Rene and Dan, attended The Ecological Society of America’s (ESA) 2019 Annual Meeting in Louisville, KY from August 11th to the 16th. All of them presented an oral presentation or a poster at the conference, attended talks, met researchers in their subfields, and attended networking events.
When not attending the conference, or a networking event, they all spent time exploring Louisville – riding Bird scooters about the town, and trying lots of local food and drink.
Malin, Zoe, and Becca all attended, and gave presentations at the Species on the Move conference at the Kruger National Park in South Africa in late July.
All of them spoke to the theme of the conference: Zoë’s “Alternative climate drivers of local species richness, colonization, and extirpation in marine fishes”, Becca’s “Adapting to change? Availability of fish stocks to fishing communities on the US west coast”, and Malin’s plenary on the “Impacts of climate warming on ectotherms in the ocean and on land.
Outside of presenting and networking at the conference, they had the chance to take in the breathtaking scenery at Kruger, exploring the savannah and catching views of baboons, giraffes, and elephants!
