[ECOLOG-L] Post-Doctoral Fellow: Coastal Wetland Carbon Sequestration in a Warmer Climate
Post-doctoral Fellow: Coastal Wetland Carbon Sequestration in a Warmer Climate Applications are invited for a Postdoctoral Fellow to investigate the biogeochemical responses of a tidal brackish marsh to ecosystem warming and elevated CO2. The successful applicant will be part of an interdisciplinary team that includes biogeochemists, microbial ecologists, and modelers. Our goal is to actively manipulate air and soil temperature (to 1.5 m soil depth), and model responses at both at an ecosystem and regional scale. The research will be conducted at the Global Change Research Wetland (G-CREW), an NSF-LTREB site and home to three related tidal marsh global change experiments (http://serc.si.edu/GCREW). The site is located on the campus of the Smithsonian Environmental Research Center, a 2,650 hectare complex of upland forest, farmland and wetlands (www.serc.si.edu). Many of the Center's 100+ full-time employees commute from nearby Annapolis, MD and Washington, DC. This is a one year, grant-funded position with continuation for 1.5 years (2.5 years total) given satisfactory performance. Candidates with research interests in biogeochemistry or microbial ecology are preferred. The position comes with a stipend of $48,000 per year plus a health care allowance. Please e-mail a short letter of interest that describes your experience and qualifications (1-2 pages), CV, and list of references by 1 Oct 2015 to Dr. Patrick Megonigal (megonig...@si.edumailto:megonig...@si.edu). Review of applications will begin immediately, and the search will continue until a suitable applicant is found. The candidate is expected to start between January and March 2016.
[ECOLOG-L] Director of Tennembaum Marine Observatories, Smithsonian Instituition
Director, Tennenbaum Marine Observatories Smithsonian Institution The Smithsonian Institution seeks an innovative leader for the newly endowed Tennenbaum Marine Observatories (TMO). For more information on the TMO, please visit: http://www.si.edu/marinegeo/. The Smithsonian has launched the TMO, an initiative envisioned as a long-term, global-scale network of ecological observatories that will be dedicated to understanding changes in the structure and function of marine ecosystems. This network is committed to innovative measurements and experiments that will span traditional disciplinary boundaries and be executed in a standardized fashion over exceptional spatial and temporal scales. It is anticipated that this approach will lead to a new and fundamental understanding of our oceans that supports sustainable use. The TMO will build upon the extraordinary strengths, capacity, and leadership of the Smithsonian Institution in marine sciences. With over 50 marine scientists, the Smithsonian expertise provides considerable depth that spans many disciplines in biology, ecology, evolutionary biology, paleobiology, anthropology, systematics, geochemistry, genetics, and other areas. The Smithsonian also has excellent infrastructure for marine science, including marine laboratories in Maryland, Florida, Belize, and Panama. The founding director of the TMO will have the opportunity to lead a cutting-edge research program that will result in high profile, policy-relevant discoveries. Characteristics that we seek in a director include: * Record of experience and scholarly achievement in core areas of TMO research. * Evidence of innovative approaches and ability to integrate ideas/concepts across traditional disciplinary boundaries. * Clear record as an effective leader in developing and implementing a major research program and in working with diverse groups of people both inside and outside the home institution. * Demonstrated strong organization and management skills. * Ability to serve as the spokesperson/ambassador to other Smithsonian programs, outside collaborators, donors, and the public. * Successful track record of competitive grant funding. The director will be based at the National Museum of Natural History (http://www.mnh.si.edu/) in Washington DC, with the opportunity to establish close affiliations with one or more other research units at the Smithsonian including the Smithsonian Environmental Research Center (http://www.serc.si.edu), the Smithsonian Tropical Research Institute (http://www.stri.si.edu), and the Smithsonian Conservation Biology Institute (http://nationalzoo.si.edu/scbi/default.cfm). The director will guide all aspects of the design, development, implementation and growth of this new initiative, in consultation with TMO participants, and will manage all TMO activities both nationally and internationally. The Smithsonian Institution is an Equal Opportunity Employer. This is a full-time, permanent position located in Washington, DC with a pay range of $150,000 to $165,300. This position will be open for applications starting December 20, 2012. Review of applications will start on January 21, 2013.

[ECOLOG-L] Post-Doc: Synthesis of Forest and Wetland Responses to Elevated CO2
Seeking a Post-Doctoral Associate to archive and synthesize data sets from two long-term elevated carbon dioxide experiments. The ideal candidate will have a background in ecosystem-level carbon cycling and skills relevant to data archiving, extraction, synthesis, and modeling. The candidate will use software designed for extracting and organizing varied and complex data sets, provide data to modelers for synthetic modeling exercises, and publish synthetic analyses of data from the two experiments. One experiment is ongoing and has 25 years of data from a tidal marsh; the other has 10 years of data from a scrub oak forest. The sets include data on carbon fluxes such as net ecosystem exchange and carbon pools in plants and soils. The Associate will interact with groups from other elevated carbon dioxide experiments engaged in synthetic modeling. The Associate will be based at the Smithsonian Environmental Research Center, a 2,650 acre complex of forests, farms, wetlands and Chesapeake Bay shoreline (see www.serc.si.edu). The Center's 100+ employees commute from both nearby rural towns and nearby urban areas such as Annapolis, MD and Washington, DC. The appointment is for one year and may be renewed for one additional year, and the salary is $45,000 per year. To apply, e-mail a letter of interest and CV to the address below. Applications will be reviewed beginning Jun 29th until the position is filled. Dr. Patrick Megonigal Smithsonian Environmental Research Center P.O.

Jobs: Two Post-Docs in Biogeochemistry/Geomicrobiology/Microbial Ecology
Job Announcement Two Post-doctoral Associate Positions We are seeking two Post-doctoral Associates to participate in NSF-funded research on the interactions between plants and microbes that regulate carbon cycling at aerobic-anaerobic interfaces. In particular we are studying resource competition between methanogens, iron-reducers and sulfate reducers in the rhizosphere of wetland plants. A central part of the project will be assessing the activity and population dynamics of Fe-oxidizing bacteria, Fe-reducing bacteria, and methanogens in response to a series of field manipulations. The target date to receive applications is April 1st 2006 and we plan to fill the position before September 2006. I. Biogeochemistry/Microbial Physiology/Microbial Ecology This position is based at the Smithsonian Environmental Research Center (SERC). The Associate should have expertise in biogeochemistry, microbial ecology or microbial physiology. The Associate will be primarily responsible for directing the field study and making rate measurements, but will have abundant flexibility to interact with team members focused on applying molecular techniques and solid-state microelectrodes to this question. SERC (www.serc.si.edu) is located in a rural setting within commuting distance of Washington, DC and Annapolis, MD. Apply to: Dr. Patrick Megonigal [EMAIL PROTECTED] II. Geomicrobiology/Environmental Microbiology This position is based at the American Type Culture Collection (ATCC). The Associate will assess the population dynamics of Fe-oxidizing bacteria, Fe-reducing bacteria, and methanogens using real-time PCR assays and TRF profiles, based both on 16S and functional genes. Cultivation methods will also be used. There will also be opportunities to conduct more detailed studies on the role of biogenic versus abiogenically formed Fe-oxides as a controlling variable in the coupling of Fe oxidation to Fe reduction and methanogenesis. This latter project will involve collaboration with researchers using state-of-the-art techniques for micro- and nanoscale mineralogical analysis. The ideal candidate will have a solid background in microbiology, experience with molecular techniques, and a willingness to learn how these techniques can be coupled with geochemical techniques to investigate outstanding questions in biogeochemistry.
