A position is available at the University of New Hampshire for a highly qualified and
motivated PhD student to conduct research in the mixed hardwood-conifer forest
ecosystems of New Hampshire related to ecosystem ecology, plant ecophysiology,
and/or ecohydrology. Broadly, the research should address questions related to how
plant species, forest ecosystems, and management practices influence water fluxes from
the individual plant to the stand or watershed scale. Ideally, the research would
enhance understanding of how climate change is affecting these ecohydrological
processes within forested landscapes. The student would have substantial flexibility to
develop the details and focus of the research once initiating her/his PhD program at
UNH. Examples of possible research questions include: How do different tree species
and/or forest ecosystems vary in their water use patterns in relation to management
history, stand structure, and/or site conditions? What are the trade-offs between
different species’ adaptive strategies to key environmental stresses, such as drought,

flooding, temperature extremes, and nutrient deposition, and the implications for long-
term shifts in species composition? How do different silvicultural practices influence plant
transpiration, canopy interception, and ultimately, site water balance? What is the
relationship between historical fluctuations in climate (e.g., rainfall, temperature, CO2
concentrations, N deposition), plant water use efficiency, and alterations in
species composition along elevational gradients and/or under different management
practices? A variety of tools will be available to the student for conducting the research,
including but not limited to sap flow techniques, stable isotope analysis, throughfall
measurements, nutrient analysis, and leaf- and plant-level ecophysiological assessments.
There would also be the opportunity to collaborate with researchers having diverse
expertise within UNH’s Department of Natural Resources and the Environment, Complex
Systems Research Center, Stable Isotope Laboratory, and the Institute for the study
of Earth, Oceans, and Space, as well as the USDA-Forest Service’s Northern Research
Station.

Requirements: Successful applicants must have obtained a research-based M.S. degree
in a discipline related to ecosystem ecology or plant ecophysiology, or equivalent
experience during or after a B.S. degree. Applicants should also have a demonstrated
ability to work both independently and cooperatively in both field and laboratory
settings, strong organizational and interpersonal abilities, and excellent written and
oral communication skills. Previous experience with plant water relations and/or stable
isotope analysis is desirable but not required.

To apply, please submit a statement of interest, full CV, copy of academic transcripts,
pdfs of relevant publications, and the names and contact information of three references
to the contact listed below via email. Review of applications will begin immediately and
continue until a suitable candidate is found. The anticipated start date is flexible, but
should be sometime between January and August 2011.
