Malin has coauthored two new perspective pieces in Science.

The first, with Nina Therkildsen of Cornell, highlights the underappreciated effects of fishing on evolutionary dynamics within (and among) exploited species. The second, with Alexa Fredston, discusses the stark choice we face between runaway climate change and a likely marine mass extinction on the one hand, and a much less consequential 2 degree rise in global temperatures on the other.

The second article was picked by the Washington Post, Inside Climate News, and National Geographic.

A visitor! The lab welcomes Jem Baldisimo.

The Pinsky Lab is very excited to host Jem Baldisimo this week! Jem is a PhD student in Kent Carpenter’s lab at Old Dominion and part of the Phillipines PIRE project. She’s visiting as part of an RCN for Evolution in Changing Seas research exchange program. During her visit, Jem will interact with lab members and learn more about various population genomic analyses, particularly computational techniques for investigating population structure and genetic diversity. She hopes to apply those skills in her own research, which involves (among other things) looking at how the aquarium trade has impacted fish populations in the Philippines.

Part-Time Lecturer position open for Molecular Ecology and Population Genomics, Spring 2022

We are currently looking for someone interested in teaching Molecular Ecology & Population Genetics in spring 2022 (11:216:454 and 16:215:554). This is the course Malin has taught the last few years, and we have funds to pay a Part-Time Lecturer for 3 credits (about $5800). This is a wonderful change to gain teaching experience in a small class setting (capped at 25 students). The course is set up as a flipped classroom, so the lectures are already recorded and the in-class exercises are already developed. The course can be taught in person, online, or in hybrid formats.

Knowledge of population genetic theory, hands-on population genomic analyses through the command line, and basic bioinformatics would be needed to teach this effectively.

Please contact Malin (malin.pinsky@rutgers.edu) for more information.

Jennifer Hoey defends her PhD!

Hoey-Pic-2

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!

Postdoc available in population genomics and global change

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.

**Position details**
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.

**Application process**
Review of applications will begin on December 16, 2019 and will continue on a rolling basis. Interested candidates should email to malin.pinsky@rutgers.edu: 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.

**Rutgers, The State University of New Jersey**
Rutgers is situated in New Jersey at a crossroads of American innovation, commerce, and culture and with a history entwined with that of the nation. Chartered in 1766, the university is the only one in the United States that is, at once, a colonial college, a land-grant institution, and a state university. Located within an easy drive of New York City, there are nonetheless an exceptionally wide array of marine, freshwater, and terrestrial ecosystems nearby, from the continental shelf and estuaries to barrier islands, coastal plains, the piedmont, Precambrian highlands, and ridge and valley geological provinces. Ecology & evolution at Rutgers consists of approximately 60 faculty and 50 graduate students pursuing research and training in conservation biology, ecosystem ecology, evolutionary biology, marine biology, microbial ecology, population and community ecology, population genetics, and restoration ecology.

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.

Six presentations at ESA and AFS!

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)

Field season in the Philippines

It is May, and we have a larger-than-usual team this year headed to Visayas State University in the Philippines to continue our research on metapopulation dynamics in coral reef fish. Michelle is leading the tagging and sample collection, Katrina is trying new oceanographic measurement sand field experiments, Allison is getting her first introduction to the system in preparation for modeling efforts, and Malin is helping out all around and catching fish (thanks to training from Tony Nahacky last year). We also have the indispensable help of local assistants Gerry Sucano and Rodney Silvano, plus Apollo Lizano (visiting student from U. Philippines Marine Science Institute). It’s great to be in the water again!

New paper: where did Nemo go?

Baby fish float on ocean currents. So where do they go? Our paper out this week in Current Biology uses DNA to answer that question for clownfish in Papua New Guinea, and about 20 km is the simple answer. What’s especially exciting is that we show how very common and easily measured population genetic patterns called “isolation by distance” accurately measure the larval dispersal process. We validated our answer against observations of dispersal for hundreds of individual larvae (an incredibly time-consuming endeavor). Our findings help open the door to applying the isolation by distance method to a much wider range of marine species.

This work was the result of an exciting collaboration with Serge Planes, Geoff Jones, Simon Thorrold, Pablo Saenz-Agudelo, Michael Berumen, Michael Bode, and others.
