42nd Annual Binghamton Geomorphology Symposium

Zoogeomorphology and Ecosystem Engineering
University of South Alabama, Mobile, Alabama
October 21 - 23, 2011
Poster Presentations and Abstracts Submission

Poster abstracts accepted through Friday, September 30, 2011 - note new deadline for submission

Call for Posters: The organizers of the 42nd Annual Binghamton Geomorphology Symposium invite submissions of abstracts for posters related to geomorphology and biogeomorphology, especially those posters related to the symposium themes of zoogeomorphology and ecosystem engineering. Poster abstracts will be published in the conference program and the poster session will be held on Saturday, October 22, 2011.

Students are especially encouraged to present their geomorphology-related research, especially those whose research overlaps the biogeography and geomorphology disciplines. A reduced registration fee is offered to students, with the lowest fee offered to those presenting posters. Students presenting posters are also eligible for a limited number of travel stipends.

Abstract format: Please limit abstracts to under 350 words and use 12-point font with one-inch margins. The abstract should be formatted with the titled centered at top with initial capital lettering, followed by author(s), affiliation(s) (academic department and university), and an e-mail address for the corresponding author. The body of the abstract should be single-spaced. Include up to five keywords at the end of the abstract. A sample abstract is provided below.

Submission: Please submit abstracts after you register for the symposium. Digital submittals (preferred) using MS Word or Adobe pdf format should be sent Carol Sawyer. If you use surface mail, send your abstract to:

Dr. Carol Sawyer
Earth Sciences
University of South Alabama
5871 USA Dr N. Room 136
Mobile, AL USA 36688-0002

Please include a digital version of the abstract on a CD. You will be receive an email confirming your submission; if you do not please contact the organizers.

Deadline: Poster abstracts are due by no later than Friday, September 30, 2011.

Poster dimensions: Posters should be no larger than 44 inches wide (1.12 meters) by 46 inches long (1.17 meters). Please note that this is a non-standard poster size.

Title: Gopher Esker Soil Temperature and Possible Impact on Conifer Establishment in Subalpine Meadows

Abstract: Alpine treeline has long been used as a proxy for global change. Past treeline research primarily attributed conifer invasion of subalpine meadows and alpine tundra to climate variability. Despite the strong control of macro-scale climate on treeline location, many micro-scale factors have been shown to influence treeline pattern and process. Microscale sites disturbed by animal activity in mountains regions have experienced altered soil characteristics that directly impacted vegetation. Animal disturbance in subalpine meadows or alpine tundra may allow conifers to establish in areas that were previously uninhabitable. Northern pocket gophers (Thomomys talpoides) in Glacier National Park have created a network of mounds and eskers in subalpine meadows that may contain dissimilar soil temperature characteristics than the surrounding matrix. Variations in surface and subsurface temperature may facilitate seedling establishment on eskers as opposed to undisturbed areas.

Gopher activity was evaluated in a conifer invaded subalpine meadow of Glacier National Park. Soil temperature of gopher eskers was recorded at surface and subsurface (depth of 10 cm) levels. The same sampling method was employed to obtain soil temperature in undisturbed areas adjacent to eskers. A paired t-test was performed to determine the difference of the average esker temperature compared to the average temperature of undisturbed areas. The mean temperature difference was significantly different from zero (two-tail p=0.0006) and suggested that soil temperature at sites disturbed by gopher activity was higher than soil temperature at undisturbed locations. Elevated soil temperatures due to gopher activity may aid seedling establishment in cooler alpine and subalpine environments.

Keywords: alpine environments, pocket gophers, zoogeomorphology
