POSTDOCTORAL POSITION on microbial metagenomics in agricultural soils over winter Fredericton, Canada Agriculture and Agri-Food Canada (AAFC), Fredericton, NB is looking for candidates for a post-doctoral fellowship position of 24 months, to examine the nitrogen cycle process and related microbial communities in agricultural fields over winter. It is generally assumed that nitrogen processes in agricultural fields are negligible during winter. However, winter production of the greenhouse gas nitrous oxide can represent up to 90% of annual nitrogen losses. Despite some evidences indicating that cold temperature and/or freezing/thawing cycles might have a substantial effect on microbial communities, there is scarce information as to how microbial communities differ from summer communities and how this translate into changes in function. The project's overall goal is to evaluate changes in denitrifier and nitrifier communities in agricultural fields over winter, determine possible environmental and edaphic factors controlling these communities and measure emissions of the greenhouse gas nitrous oxide, as well as denitrification and nitrification rates. The successful candidate will be working on a major collaborative initiative including university (Dr. David Burton, University of Dalhousie) and AAFC researchers (Dr. Bernie Zebarth (Fredericton) and Dr. Frank Larney (Lethbridge, AB)). Applicants should have experience in next generation sequencing of microbial communities. Experience with denitrifier or nitrifier communities is not required; scientists with training in other soil communities i.e. bacterial and/or fungal from soil, sediment or water are welcome to apply. Knowledge of English is required. The candidate needs to be Canadian citizen or permanent resident and meet the criteria of the NSERC Visiting Fellowship in Canadian Government Laboratories Program (<http://www.nserc-crsng.gc.ca/Students-Etudiants/PD-NP/Laboratories-Laboratoires/index_eng.asp>http://www.nserc-crsng.gc.ca/Students-Etudiants/PD-NP/Laboratories-Laboratoires/index_eng.asp).
