IPY Postdoctoral Positions Available International Tundra Experiment (ITEX) University of British Columbia Vancouver, Canada
Application Deadline: 11 April 2007 For further information about ITEX, please go to: http://www.geog.ubc.ca/itex or contact: Greg Henry E-mail: [EMAIL PROTECTED] ---------------------- The University of British Columbia (UBC) invites applications for two IPY postdoctoral fellowships as part of the International Tundra Experiment (ITEX). Tundra Vegetation Ecology: Synthesis of Vegetation Change in ITEX and Other Experiments The candidate will help to organize syntheses of vegetation and soils data from experimental plots associated with ITEX, with a focus on responses in control plots to climate variability. The project will also involve searching for other circumpolar vegetation data sets for use in the synthesis. Field research will be conducted at a long-term ITEX site on Ellesmere Island in the Canadian High Arctic and will include standardized measurements of species abundance and plot-level NDVI. The candidate is expected to have strong skills in field and analytical techniques in vegetation ecology and in climate-plant interactions. An ability to build and manage databases will be an important asset. In addition, the candidate will be involved in the operation of the ITEX Secretariat at UBC and interact with ITEX and IPY researchers involved in related research. The candidate will also help supervise graduate and undergraduate students involved in research projects with the tundra ecology group at UBC. Ecosystem Ecology: Carbon and Nutrient Dynamics in Tundra Ecosystems The candidate will conduct measurements of net ecosystem exchange (NEE) at a wide variety of tundra sites across the Canadian Arctic as part of a Canadian IPY project. Measurements of Leaf Area Index (LAI), biomass, plot level NDVI and soil properties will also be made to relate to NEE. Sites will include long-term and newly established experimental plots. In addition, the candidate will help to organize a synthesis of soil carbon and nutrient dynamics across the Canadian and ITEX networks. This will include ensuring all sites receive ion exchange membranes for measurements of nutrient flux rates in experimental plots and organizing analysis of soil samples and data. The candidate should be familiar with static chamber measurement methods of NEE and to help develop protocols for the measurements across ITEX sites. The candidate will contribute to a synthesis of NEE measurements in tundra during IPY. The candidate will also participate in the operation of the IPY project office at UBC, including supervision of students and staff. Each position is for a maximum of three years. The preferred start date for the positions is 1 May 2007, though could be earlier. Applicants must hold a PhD (or equivalent) relevant to the research described above. Applications should contain a CV, full publication list and electronic copies of relevant publications and contact information for two references. Please submit applications by 11 April 2007 to: Greg Henry, Chair International Tundra Experiment Department of Geography, University of British Columbia E-mail: [EMAIL PROTECTED]
