Landscape Level Effects on Stream Carbon Cycling and Export– Scott Kelsey

Scott’s project examines the effect that watershed-scale spatial processes such as land use and insect pest invasions have on the character and concentration of carbon exported from the watershed.  Potential sources of carbon (such as plants, soil, etc.) throughout the watershed can be greatly impacted by human activity (farming) or invasive species (e.g., Emerald Ash Borer), increasing C export.  By understanding the character of carbon exported from watersheds of varying watershed-scale conditions (e.g., land use type), we can not only better understand how anthropogenic influences change carbon export on a landscape level scale, but we also can better understand the sources and pathways that carbon takes from headwater streams to the ocean, influencing food webs along the way.
