STREAM HABITAT CHARACTERISTICS INFLUENCING METHANE CONCENTRATION IN NORTH BUFFALO CREEK, GREENSBORO, NC
Methanogens utilize reactants found naturally or as a result of the breakdown of organic matter to produce methane through a process called methanogenesis. This process requires anoxic conditions, and readily happens in the sediments of aquatic ecosystems. The amount of methane initially produced by methanogens in stream sediments is dependent on several factors. A survey of thirteen sites located along North Buffalo Creek (NBC), in Greensboro, NC was performed during the Winter of 2015. Data analysis suggests that stream sediment composition (sandy vs. coarser substrate) and the amount of undisturbed riparian zone influence methane concentrations in streamwater and porewater. Sandy sediments potentially provide more suitable anoxic microhabitats for methanogens. Increased organic inputs from undisturbed riparian zones could be providing reactants required for in-stream methanogenesis. Intact riparian zones could also influence methane concentrations in streams through subsurface inputs of methane. However more research is needed to determine how substrate composition and riparian vegetation influence stream methane cycle processes.
