Plant Ecology/Genetics: I am looking for a post doc to work on the ecological genetics of Phalaris arundinacea, reed canary grass. Reed canary grass, Phalaris arundinacea, is a tall, clonal, cool-season perennial grass. It was originally introduced into the U.S. as a forage crop, but has since escaped domestication and spread into wetland and pasture communities. Reed canary grass exhibits variation in its aggressiveness. The objective of this research is to determine the characteristics that make reed canary grass an aggressive invader and how these vary among genotypes and environmental conditions. Using electrophoresis, we have already identified different genotypes taken from a variety of habitats to be used in greenhouse and field studies. Previous studies indicate that genotypic differences have large effects on survivorship and growth. The post doc would be responsible for both greenhouse and field experiments. Starting date is flexible but not later than June 1, 2000. Funding is from the USDA. To apply, please send CV, reprints and the names and addresses of three references. If interested, please contact: Dr. Jane Molofsky, Department of Botany, University of Vermont, Burlington, VT 05405, 802-656-0430, email: jmolofsk@zoo.uvm.edu

Plant/Soil Science: Applications are invited for a post-doctoral research scientist to work on a project, funded by the Home Grown Cereals Authority, investigating opportunities for manipulating root-shoot signalling to improve crop growth on dry soils. A large proportion of the variation in cereal yields that exists from site to site in the UK is believed to result from differences in water availability. Low availability may be associated with light soils, or shallow soils resulting from compacted or naturally hard-setting sub-soil layers. Often the effects are subtle. In untilled zones, roots can become clustered in cracks and pores, leading to localised water deficits even when the bulk soil water potential is high. It is now known that root systems are able to sense changes in soil conditions and signal these to the shoot. As the soil dries, abscisic acid (ABA) is synthesised by roots and delivered to the shoot inhibiting leaf expansion and sometimes inducing stomatal closure before a significant reduction in leaf water status develops. The response of the leaves to ABA is modified by the pH of the xylem sap, which also increases as the soil dries. Where soil water availability varies through the soil profile, growth of roots into moist soil layers may help dilute the 'signal' produced by roots in the dry zones, thus delaying a reduction in leaf expansion and stomatal conductance. Significant improvements in crop performance might be achieved by manipulating the root-shoot signalling system so that canopy growth and function are sustained for longer as the soil dries. This might be achieved by selection of genotypes, or elucidation of management techniques, which a) lower the soil moisture content at which ABA concentrations and xylem sap pH are increased and b) promote growth and proliferation of roots in moist soil zones. Applicants should have a PhD, with relevant post-graduate experience of research on plant root systems, and preferably experience in plant water relations. Good project management skills are essential requirements for this post. The salary scale is 14,500 - 20,100 per annum (25,700 per annum possible with performance pay) annum and is for a fixed term of 3 years. The post will be based in the Crop Health Department, at SAC's Aberdeen campus. Informal enquiries should be made to Dr I. Bingham: Tel 01224 711280; Fax 01224 711293; email i.bingham@ab.sac.ac.uk.

Forest Ecology/Herbivory: The Mountain Forest Ecology Group in the Department of Forest Sciences of the Swiss Federal Institute of Technology in Zürich, Switzerland, anticipates funding for a Post-doctoral Fellow Position to work on a research project entitled "Long-term forest dynamics under herbivore pressure: model improvement and simulation of future forest structure". There are widespread concerns in the European Alps that current population densities of large mammals (primarily red and roe deer) may threaten the recruitment of trees in mountain forests, with potentially significant consequences for the function of protection forests and, eventually, human welfare. This project will employ a model-based approach for evaluating the relative importance of the various effects of ungulates on tree population dynamics. Innovative methods will be used to foster the dialogue between forest practitioners and the researchers to optimize model development as well as the dissemination of research results. The project is embedded in a larger interdisciplinary research programme that is about to start in 2000. Candidates should have a PhD in ecology, forest sciences, environmental sciences, or a related field. Experience with the development, testing and application of ecological models of long-term successional processes is highly desired. The project will have a theoretical as well as a field component; the successful candidate will plan and perform a field campaign to support the development, parameterization and testing of the model. The Mountain Forest Ecology Group at ETHZ (http://www.fowi.ethz.ch/pgw) is a small research group founded in late 1999. We study the structure and function of mountain forest ecosystems to provide the basis for improving their management in an era of multiple and sometimes conflicting forest uses, including protection of people and infrastructure, wood production, carbon storage, water resources, biodiversity, and recreation. Screening of applications starts immediately, and applications are accepted until the position is filled. Starting date for the position could be as early as April 1, 2000. The initial contract will be for a year, with the possiblity of prolongation by another two years. The salary will partly depend on qualifications and experience of the candidate and can be expected to be around CHF 80000 (US$51000) per year. Applications including the names and addresses of two references (including their phone number and e-mail address) should be sent to Prof. Dr. Harald Bugmann, Mountain Forest Ecology ETHZ, ETH-Zentrum HG G21.3, CH-8092 Zürich, Switzerland.
