GeoBiology 2006
Welcome to the student research project results page Integral to the educational emphasis of this summer course is to see that students work together on projects that result in presentable results. The posters that appear on the links below represent the culmination of 5 weeks of work by GeoBio students, TAfs, demo reps and faculty. Each of the topics define questions that require a geobiological investigation, and the results of these studies are presented here. We regard the data contained on the posters as property of the course. Thus, if you wish to utilize any of these data, please contact course director Will Berelson (berelson@usc.edu) and acknowledge the Agouron International GeoBiology Summer Course, 2006.
Research Projects: Yellowstone A - Investigation of functional genes operational an d active at high temperatures; perform enrichment experiments for hydrogen oxidizing thermophiles Yellowstone B - Examine the relationship between Archaeal groups and their location within Yellowstone Hot Springs microbial mats and stromatolites. San Pedro A - Investigation of N dynamics in the suboxic sediments of San Pedro Basin (900 m), searching for planctomycetes involved in Anammox reactions and anaerobic ammonia oxidizing archaea and bacteria San Pedro B - Study the microbial role in metal cycling within San Pedro Basin sediments using gradient enrichment techniques, also, characterize proteins involved in Mn oxidation Fuel Cells - Investigate the biofilm formation on anodes and cathodes from sediment ebatteriesf, search for functional electron transport genes, conduct enrichments for Fe (II) oxidizing microbes Biosignatures - Examine the architecture of Yellowstone Hot Spring deposits and characterize the microbial signature in the mineral deposit, compare modern hot spring deposits to ancient, extract and analyze organic biomarkers Cat Harbor - Compare and contrast two photosynthetic bacterial mats within Cat Harbor, characterize the cyanobacterial community, analyzed oxygen production and consumption within these mats, search for archaeal ammonia oxidizers and their functional genes
