[ECOLOG-L] REU Summer Research Experience for Undergraduates - Tucson, AZ
REU (Research Experience for Undergraduates) is a National Science Foundation-sponsored program wherein undergraduates receive a stipend (up to $5,760 or $480 per week for 10 to 12 weeks) to conduct independent research projects under faculty guidance and mentorship. The School of Natural Resources at the University of Arizona (UA) has two openings for REU scholars for the summer of 2009. One position is for a collaborative study with Dr. Steve Archer (UA) and Dr. Susan Schwinning (Texas State University) investigating why some shrubs are more successful than others in invading and establishing in grasslands. Another position is for a collaborative study with Dr. Steve Archer and Dr. Dave Breshears at UA and collaborators at New Mexico State, Loyola University and the University of Kentucky examining how plant litter decomposition in deserts is influenced by interactions between radiant energy and wind and water redistribution of soil. In addition to their own investigations, REU scholars will participate in controlled environment studies on the UA campus; and in field studies at the Santa Rita Experimental Range just south of Tucson. For more details on the two projects and application procedures, see http://ag.arizona.edu/research/archer/ . Application Deadline: April 30, 2009; or until suitable candidate is hired.

[ECOLOG-L] Graduate Research Assistantship: Decomposition-Soil erosion-UV interactions
We invite applications for a graduate research assistantship (GRA; Ph. D. level preferred; 3 years funding) from students interested in decomposition processes in desert ecosystems. Most of what is known about decomposition is from studies in high rainfall areas, but this knowledge does not translate well to dryland ecosystems. Recent studies suggest solar ultra-violet radiation is a major driver of decomposition in drylands; however, other studies indicate the level of mixing of wind/water-transported soils with litter is a key factor. This project seeks to resolve these competing explanations via a series of laboratory studies and field experiments in Arizona designed to measure light energy-soil movement- decomposition interactions. These linkages will be assessed in the context of woody plant encroachment into grasslands, a globally extensive vegetation change in drylands. The graduate research assistant will be based at the University of Arizona with Steve Archer and Dave Breshears. The GRA will participate in an interdisciplinary investigation seeking new insights into processes affecting desert soil fertility and carbon storage by combining the disciplines of plant community ecology, ecosystem science and earth science in a novel framework. The GRA’s project will be field-oriented and will quantify spatial patterns of litter input and its translocation by wind and water and litter mass loss in contrasting plant community configurations. The GRA will work closely with collaborators at New Mexico State University (Heather Throop; litter chemistry), the University of Kentucky (Rebecca McCulley; microbial communities) and Loyola University (Paul Barnes, photobiology). For additional details on the project see http://www.snr.arizona.edu/project/decomposition. Starting date negotiable, but Summer 2009 is preferred. The assistantship includes an annual salary of $14,677 (MS) or $15,990 (PhD); waiver of out-of-state tuition; full remission of in-state tuition; and health insurance. Applications will be accepted until 31 May 2009 or until suitable candidate is found, and should include 1) a statement of interests and goals, 2) a CV with copies of transcripts and GRE scores, and 3) names and contact information for 3-5 references. For general admission requirements see http://www.snr.arizona.edu/academic/grad . Applications and information requests should be directed (preferably via email) to Steve Archer (sarc...@ag.arizona.edu), 325 Bio Sciences East, School of Natural Resources, University of Arizona, Tucson, AZ 85721-0043; 520 626-8791).

[ECOLOG-L] Paid assistant needed, pika research, Glacier Nat. Park, June 5 - Sept. 30
Pika/global warming project fieldwork, paid - Glacier National Park, Montana - June 5 – September 30, 2009. The study involves locating and observing pikas (small lagomorph) while hiking at high altitudes, backcountry camping, working with a GPS receiver, and identification of plants and other mammals. Applicants should have experience with extended backpacking excursions, be in excellent physical condition, and experience with some ecological field work is a plus. Expect early mornings, unpredictable weather, wild animals, and gorgeous scenery. There are also opportunities to work with GNP’s citizen science project that involves interaction and communication with the public about the project and related global warming science. The assistants will work with the project leader (Lucas Moyer-Horner, U-Wisconsin-Madison). The paid position ($100/week stipend) is competitive. The successful applicant must be able to start no later than June 30th, stay through Sept. 30th, and have their own vehicle. Housing and park passes will be provided. To apply, please send an email to lrmoy...@wisc.edu, with the subject PIKA GNP. Please include a letter of interest, resume and one letter of recommendation. Applications will be accepted until the position is filled. --- Lucas Moyer-Horner PhD candidate Zoology Department University of Wisconsin-Madison Mountains are the beginning and the end to all natural scenery -John Muir
[ECOLOG-L] Ph.D. students in microbial ecology
The microbial ecology group (headed by Dr. Dittmar Hahn) at the Department of Biology at Texas State University – San Marcos (www.bio.txstate.edu) is seeking Ph.D. students to study growth and nitrogen-fixation of the actinomycete Frankia in the rhizosphere of host and non-host plants and in bulk soil using different molecular tools (e.g., in situ hybridization, RT- qPCR). Ph.D. candidates must have a Masters degree, and preferably hands- on experience in microbiology, the use of molecular techniques and statistics. The ability to work independently but within a team environment is required. For more information and instructions on applying, please contact Dr. Hahn at d...@txstate.edu or at (512) 245 3372.
[ECOLOG-L] graduate student assistantship
I am inviting applications for a Masters level student in the Department of Forestry, Michigan State University. The successful candidate will have two years of graduate research assistantship support to work on a project funded by multiple partners (TNC, MDNR, USFS, and Forests for the Future). Using a long-term, multi-stand, manipulative harvest experiment in managed northern hardwood forests, the project goals are to identify the factors contributing to declining tree regeneration species diversity and to find practical measures that could be used to reverse this trend. The student will spend considerable time at field experiment sites in the northern Lower Peninsula and eastern Upper Peninsula of Michigan, where housing will be provided, and will have the opportunity to interact with project partners. The successful candidate can start May (preferred) or September 2009 For more information contact: Mike Walters Associate Professor Department of Forestry Michigan State University East Lansing, Michigan 48824 517-355-1762 mwalt...@msu.edu
