>GRADUATE STUDENT ASSISTANTSHIP - UNIVERSITY OF IDAHO
>An assistantship is available for a M.Sc. student in Forest Pathology in
>the Department of Forest Resources of the University of Idaho. The student
>would focus on the use of nitrogen isotope ratios to assess
>hyperparasitism (i.e., parasitism of parasites) in fungal parasites of
>plants. Hyperparasitism is the basis for classical biological control.
>However, fungi that appear on parasite-killed host
>tissue may be hyperparasites or they may, in contrast, be opportunistic
>necrotrophic pathogens of the plant host. Preliminary research suggests
>that nitrogen isotope ratios would help to clarify relationships within
>tritrophic systems anchored by forest trees.  Nitrogen isotope ratios in
>eight tritrophic systems with relevance to Western forests will be
>determined.  In the three most important systems, inoculations will also be
>performed to determine whether the putative hyperparasite reduces fitness
>of the parasite.  Two ditrophic systems will also be considered for
>comparative purposes.  Applicants should be able to start by fall 2000, and
>ideally would have had coursework in Forest Pathology, Mycology and Plant
>Physiology.  Research would involve field collections in Northwest forests
>and inoculation studies in addition to the isotope work.   To apply, please
>contact by email before May 15th: Dr. George Newcombe, Department of Forest
