Postdoctoral Research Associate - Tree Physiology

Position No. 002-841

STARTING DATE: Oct. 1, 1997
 APPLICATION CLOSING DATE: Aug. 1, 1997

CONTEXT: We seek a Research Associate to participate in a three-year project to investigate the effects of tree age and size on stem hydraulic conductance and canopy photosynthesis. Previous research showed that age and size-related differences in hydraulic conductance may substantially limit maximum height and productivity of ponderosa pine trees. A primary objective of this project is to determine whether trees in a variety of other ecosystems exhibit similar hydraulic limitations. We will also refine and parameterize a process-level model of hydraulic limitations to tree growth. The primary study locations are canopy crane sites in Panama and Wind River, Washington, a Quercus garryanna site in the Willamette Valley, OR, and a Pinus ponderosa site in the Oregon Cascades. Much of the work will be carried out at these remote locations, within the canopies of tall trees.

Principle investigators are:

The project is funded by a grant through the USDA-Competitive Grants Research Program.

RESPONSIBILITIES: The Research Associate will have primary responsibility for site management and field measurements at the two canopy crane sites and at the Willamette Valley site. This will include maintenance of meteorological equipment, installation of experimental treatments to manipulate hydraulic conductance, and measurements of sap flow and leaf gas exchange. He/she will also participate in all other aspects of the project, including supervision of student workers in the laboratory, data management, data analysis and writing of reports. Extensive travel will be required to the study sites, including at least three months continuous stay at the Panama site in winter/spring 1998.

QUALIFICATIONS: A Ph.D. degree in tree physiology, biophysics, or plant ecophysiology, experience with ecophysiological measurements (gas exchange in the field, sap flow), experience with environmental measurements and data loggers. Previous research experience involving stable isotopes of carbon and/or physiological process modeling is desirable. Candidates with demonstrated ability to formulate hypotheses and to design, implement, and report results from research in plant ecophysiology are preferred.

EMPLOYMENT CONDITIONS: Full time (1.0) fixed-term, 1-year position. Reappointment is at the discretion of the dean. Salary $30,000 - $32,004.

OTHER BENEFITS: Competitive medical, dental and life insurance plans.

Postdoctoral Fellow

Postdoctoral associate position is available starting October 1, 1996, for two years, to study the water relations of Rhododendron species at Coweeta LTER in North Carolina and at Andrews LTER in Oregon. The applicant must have a Ph.D. and should have experience in methods used for study of plant ecophysiology including water relations and gas exchange processes. Experience with measurement of stomatal conductance, stem hydraulic conductance, photosynthesis, and microclimatic parameters is preferred although not absolute. A letter of application, curriculum vitae, statement of professional goals, and the names and numbers of three references should be sent immediately. Applications will be accepted until a suitable candidate is identified. All correspondence should be directed to:

Postdoctoral Fellow

QUALIFICATIONS: Graduation from an accredited college or university with a Ph.D. in Plant Physiological Ecology or related field. Experience in the design, collection, analysis, and reporting of process-based studies of root function is essential. Experience with studies of root dynamics, including minirhizotron studies, as well as with the design of both controlled environment studies and field studies is highly desirable. The candidate must be a U.S. citizen in order to obtain non-restricted security clearance to work within the Nevada Test Site (NTS) and must be capable of extended field work under harsh desert conditions.

POSITION DESCRIPTION: The Postdoctoral Fellow will have primary responsibility for the design, collection, analysis, and reporting of controlled environment and field studies to determine the effects of increased atmospheric CO2 on both the uptake kineti cs of plant roots and on resource acquisition by Mojave Desert vegetation. The Postdoctoral Fellow will also assist with measurements of fine root dynamics at the NTS Desert FACE Facility (NDFF). NDFF is an experiment in the Mojave Desert that utilizes Free Air CO2 Enrichment (FACE) technology to simulate the global atmospheric environment of the 21st century. The Postdoctoral Fellow will also assist with the design, collection, analysis, and reporting of supporting experiments and studies.

SALARY: Salary will be commensurate with qualifications and experience.

APPLICATION DEADLINE: Consideration of applications will begin on September 3, 1996 and continue until the position is filled.

STARTING DATE: October 1, 1996 or as soon as possible thereafter.

APPLICATION PROCEDURE: Send letter of application, curriculum vitae, and the names, addresses, telephone numbers, and email addresses of 3 references to:
