Putting endangered wildlife in a corner

Our new paper on extinction risk in marine and terrestrial species is out today in PNAS, “Range contraction enables harvesting to extinction” [free preprint here]. Led by Matthew Burgess at UCSB, the research shows that shrinking distributions puts many animals at further risk from extinction as their abundance decline. While harvesters (fishers or hunters) are typically expected to stop harvesting when a species becomes rare and the costs of harvest become too high, contraction of a species into dense clusters can keep harvesting profitable, even at very low abundance. Examples of species with these contractions include Bengal tigers, Asian elephants, and bluefin tunas.

New paper: Who should pick the winners of climate change?

It is tempting to try to guess which species will be the winners of climate change, and which the losers. But our new paper in Trends in Ecology and Evolution suggests that we should avoid doing that when we design management and conservation measures. Instead, we propose harnessing the diversity and evolutionary capacity of the natural world as a climate adaptation strategy by designing “adaptation networks.” We focus on coral reefs as a particularly salient example.

Ed at the EcoSummit in Montpelier

tekwa_talk_slideEd was at the EcoSummit conference in Montpellier (Sept. 1) to present “Why do fisheries evolve different harvest rates?”.  The conference theme was Engineering Sustainability, but covered a wide range of sustainability topics. Also a nice chance to drink some wine and visit with Michel Loreau!

Multiple PhD and postdoctoral positions in climate change ecology and evolution

Multiple PhD and postdoctoral positions in climate change ecology and evolution

Three postdoctoral positions and one PhD position are available in the Pinsky Lab at Rutgers University to work on climate change ecology and evolution in marine ecosystems. The positions represent an exciting expansion of research efforts in this area. Broadly, research in the Pinsky Lab uses empirical data, mathematical models, and population genomics to study global change in the coastal ocean.

Key themes across all new positions include understanding the ecological and evolutionary processes that determine how climate variability and climate change filter through ocean communities to affect human behavior and the success or failure of conservation efforts. Postdocs and students will join an international network of collaborators across conservation, marine science, climate science, economics, sociology, and policy, including Josh Abbott (Arizona State U.), Daniel Schindler and Andre Punt (U. Washington), Dan Holland and Melissa Poe (NOAA), William Cheung and Daniel Pauly (U. British Columbia), Jorge Sarmiento (Princeton), Carl Folke (Stockholm U.), and Pat Halpin (Duke).

Three (3) postdoc positions are open:

1) Coupled Natural Human (CNH) systems postdoc: The postdoc will take the lead on a research project investigating the causes and consequences of ecological synchrony in the California Current large marine ecosystem. Key questions include how portfolio effects emerge in open systems and how oceanographic processes and fishing interact to affect population dynamics. The postdoc will also be part of a broader NSF-funded team studying coupled social-ecological dynamics and feedbacks from physics to fish to people.

2) Nereus Fellow: As part of the Nereus Program (http://www.nereusprogram.org), the Fellow will design and lead empirical research to understand the consequences of climate change and shifting species distributions for human behavior and adaptation in marine ecosystems. Resources for the research include large datasets of fishing vessel behavior over decadal time-scales, as well as other datasets on environmental changes and ecological states.

3) Eco-evolutionary dynamics postdoc: The postdoc will develop models and theory to understand the extent to which ecological turnover and evolutionary rescue could preserve coral reef function over the coming centuries, and whether conservation efforts can facilititate the adaptation process at the landscape scale. Application of the theory to case studies in three geographies will also be part of the research.

All postdoc positions are two years.

One (1) graduate assistant position is open, preferably for a Ph.D. degree:

1) CNH Graduate Assistant: The GA will use statistical and process-based models to understand the mechanisms linking climate variability to marine animal population dynamics in the California Current large marine ecosystem, including recruitment and distribution. The GA will also be part of a broader NSF-funded team studying coupled social-ecological dynamics and feedbacks from physics to fish to people.

Across all positions, the ideal candidates will be skilled with data analysis, statistics, and ecological modeling (or a strong aptitude for learning these skills, in the case of the GA). 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. For postdoctoral applications, a promising record of publication is highly valued. The successful applicants will be independent, motivated problem solvers who communicate well and enjoy working in a collaborative setting.

The positions will be based at Rutgers with extensive opportunities for research visits across campuses, including U. Washington, U. British Columbia, and NOAA offices. Additional opportunities are available to interact with scientists at  the Institute of Earth, Ocean, and Atmospheric Sciences; the Geophysical Fluid Dynamics Lab; the Princeton Environmental Institute; the Center for Discrete Mathematics and Theoretical Computer Science; and beyond.

**Application process**

The postdoc start dates are flexible and the positions are open until filled. The GA will begin in summer or fall 2017. Review of postdoc applications will begin on October 1, 2016 and will continue on a rolling basis. Review of GA applications will continue until December 2016, when applications to Rutgers graduate programs are due.

Interested postdoc candidates should submit: 1) a one­-page cover letter that describes which position(s) they are applying for (and preferred position if applying to more than one) and their preferred start date, 2) a two­-page research statement describing their relevant background and anticipated research approach to the problem they would be addressing, 3) a CV, and 4) the names and contact information of three other scientists familiar with their work.

GA applicants should include a 1-2 page cover letter describing their interests, CV, a recent transcript, GRE scores, and contact information for three references. Qualified GA candidates will be contacted and encouraged to apply to the graduate program in either Ecology & Evolution (http://ecoevo.rutgers.edu/) or Oceanography (http://marine.rutgers.edu/main/IMCS-Academics/Graduate-Program-in-Oceanography.html), depending on student interests. Ph.D. applications to Rutgers are due in December.

Please submit all materials to malin.pinsky@rutgers.edu with “Postdoc application 2016” or “Graduate application 2016” as the subject.

Ph.D. position open in coral reef metapopulation dynamics

IMG_1011_modWe’re looking for good Ph.D. applicants! We have a Ph.D. position open to research marine metapopulation dynamics using field work combined with population genomics. Our research group has interests in marine ecology, population genetics/genomics, climate change, biogeography, dispersal, and fisheries. Student projects will generally overlap with these areas, but independent thinking and new ideas are strongly encouraged.

Potential projects include (but are not limited to) questions of metapopulation dynamics, demography, dispersal, local adaptation, thermal physiology, and implications for marine reserve design. We do extensive fieldwork in the Philippines with clownfish, and excellent opportunities exist to build from four years of existing data. Projects would likely involve a mix of field work, genomic wet lab work, bioinformatics, and ecological modeling. Enthusiasm, drive, excellent written and oral communication abilities, and strong quantitative skills are necessary. Scientific diving certification is encouraged, but training can occur during the graduate program.

Interested candidates should send an email to malin.pinsky@rutgers.edu describing their motivation and research interests along with a CV, GPA, GRE scores (if available), and three references. In-progress applications to external fellowships are viewed favorably. Qualified candidates will be contacted and encouraged to apply to the graduate program in either Ecology & Evolution or Oceanography, depending on student interests. This is a funded position, though Ph.D. students will be encouraged to apply for external fellowships.

Breeding like rabbits doesn’t work for fish

We have a new paper out in Proceedings B, “Fishing, fast growth and climate variability increase the risk of collapse.” Analyzing data from fisheries around the world, we show that patterns in the ocean are nearly the opposite of those on land. Slow-growing species like lions and tigers may be most at risk of extinction on land, but in the ocean, it’s the “rabbits” that are most sensitive. We find that fast-growing species like flounder and sardines are more than three times more likely to collapse when they experience overfishing than their slower-growing cousins. Populations that experience strong climate variability are also more at risk.

Tim Essington also had a nice paper exploring some of these patterns among small pelagic species earlier this year. Definitely worth a read, plus the following discussion (here and here).
