NEW- Postdoctoral Position Available -- July 2, 2018 (open until filled)
Postdoctoral Research Associate in Plant Ecophysiology / NB50676169
A postdoctoral position is available in the Environmental Sciences Division and Climate Change Science Institute of Oak Ridge National Laboratory to investigate plant carbon physiology and water relations in context of climate change. You will join a multi-disciplinary team of investigators undertaking a broad, integrated field experimental study to assess and model the response of a northern peatland ecosystem to increases in temperature and exposures to elevated atmospheric CO2 concentrations.
Interested candidates should send a cover letter, cv and names of three professional references to: Dr. Jeff Warren, email@example.com
You will possess a Ph.D. with comprehensive experience in plant physiological ecology and one or more of the following disciplines: photosynthesis/respiration, plant water relations, biophysics, mechanistic modeling of plant physiological processes, or global change ecology. Prior experience with experimental field ecological research and associated laboratory approaches (including gas exchange and fluorescence, sap flow, respiration and stable isotopes) and an appreciation of data-model interactions is highly desirable. Your research will focus on one or more of the following: photosynthetic and respiratory acclimation to elevated CO2 and T, plant hydraulics, phenology, morphology and biochemistry; although focused self-directed research is expected. While woody plants dominate the shrub level and overstory at the site, herbs, grasses and non-vascular plants are also of interest and some work may be focused on these non-woody species. The position will require extensive self-directed fieldwork at the flagship ‘Spruce and Peatland Responses Under Climatic and Environmental Change’ (SPRUCE) experimental field site in northern Minnesota (http://mnspruce.ornl.gov/). Residency at ORNL in Tennessee or at the MN field site is a possibility. Ability to work as part of a team and be comfortable in a multi-disciplinary environment is critical. You will be a self-starter and have a proven record of research that resulted into high-quality peer-reviewed journal publications, and national and international presentations.

NEW- Two Funded PhD Positions Available in Boreal Tree Responses to Climate Change
Two Funded PhD Positions Available in Boreal Tree Responses to Climate Change
Seeking outstanding applicants for two PhD positions investigating the combined effects of elevated CO2 concentrations and temperatures on boreal forest tree physiology. Students will be based in Dr. Danielle Way’s lab (http://daniellewayblog.wordpress.com/) in the Department of Biology at the University of Western Ontario (London, Ontario, Canada), as part of a group of students researching plant responses to climate change. The positions are funded through a recent NSERC award for three years (2018-2021), but PhD stipends are guaranteed for 4-5 years, depending on the applicant’s academic history.
The first student will help determine the impacts of combined elevated CO2 and warming on tree photosynthetic and respiratory traits at the Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment (https://mnspruce.ornl.gov/). SPRUCE is a flagship experiment for the U.S. Department of Energy, led by Oak Ridge National Lab. The student will be based in London, Ontario, Canada at the University of Western Ontario in the Department of Biology, but will work closely with scientists from Oak Ridge National Lab and the University of Minnesota during summer measurement campaigns in Minnesota in 2019 and 2020.
The second student will be responsible for leading a glasshouse experiment at the Biotron Centre for Experimental Climate Change Research (https://www.uwo.ca/sci/research/biotron/) at the University of Western Ontario, investigating how combinations of elevated CO2 concentrations and temperatures impact photosynthetic and respiratory traits in eight boreal species.
Both students will also have the opportunity to interact with researchers from the Canadian Forest Service, who are collaborators on the project.
Applicants should create a single pdf that includes a cover letter, curriculum vitae, unofficial transcripts, and contact information for three references. Please email the pdf as an attachment to Dr. Danielle Way (email@example.com) with “PhD position in boreal climate change” in the subject line.
Desirable applicants will be invited to apply for admission to the graduate program in the Department of Biology at the University of Western Ontario, preferably with a January 2019 start date.
SPRUCE S1 Bog Pretreatment Seasonal Photosynthesis and Respiration of Trees, Shrubs, and Herbaceous Plants, 2010-2015
This data set contains the empirical biochemical, morphological, and physiological data collected between 2010 and 2015 on an herb (Maianthemum trifolium), understory shrubs (Rhododendron groenlandicum, Chamaedaphne calyculata, Kalmia polifolia and Vaccinium angustifolium) and overstory trees (Picea mariana and Larix laricina) in the S1-Bog at the USDA Forest Service Marcell Experimental Forest (MEF) in northern Minnesota, USA. Data reported include the measurements of photosynthetic light and CO2 response curves, and dark respiration, as applied to standardized curve-fitting programs to estimate biochemical parameters.
SPRUCE S1 Bog Seasonal Patterns of Nonstructural Carbohydrates in Larix, Picea, Rhododendron, and Chamaedaphne, 2013
This dataset reports the results of nonstructural carbohydrate (NSC) analyses of foliage/twig/root tissues collected at the SPRUCE site in 2013. Samples were obtained at various locations around the S1 Bog. These are pretreatment vegetation samples, collected prior to initiation of the SPRUCE experiment heating and elevated CO2 treatments.
