A postdoctoral associate position is available to examine how
whole-plant carbon source/sink relationships may change with age and an
edaphic stress in loblolly pine, with an emphasis on root system carbon
demands. We are experimentally evaluating possible genetic differences in
belowground biomass and carbon allocation and partitioning of four
different fast- and slow-growing families of loblolly pine located in
Scotland County, NC, under optimal nutrition and ambient soil conditions.
Minirhizotron technology and sequential coring are being used to assess
root system turnover. Carbon acquisition and subsequent allocation to
growth and storage are being estimated by measuring net photosynthesis,
conducting whole-tree harvests, analyzing total nonstructural
carbohydrates and through stable isotope analysis. The successful
candidate must have laboratory experience in plant tissue analysis.
Applicants should have a Ph.D. in plant physiology, forestry or plant
physiological ecology. Applicant must be able to travel to the North
Carolina field site four times a year for periods lasting two weeks each
trip. The position is available immediately. Salary is commensurate with
experience. Please send a cover letter describing research experience and
goals, curriculum vitae and names of three references to Dr. Mary A. Topa,
Boyce Thompson Institute for Plant Research, Tower Rd., Ithaca, NY,
14853-1801; telephone 607-254-1263, FAX 607-254-1242, email
