LAND USE EFFECTS ON ANNUAL STREAM METABOLISM IN KANSAS
Synthesis of daily metabolism measurements from different streams and rivers have revealed a great deal of temporal variation in gross primary production (GPP) and ecosystem respiration (ER). However, attempts to relate variation in GPP and ER to land use remains limited. Land use may be an important control on ecosystem metabolism because nutrients often limit the amount of biological activity in ecosystems. Thus, we ask: How does land use and associated differences in nutrient inputs affect stream metabolism? We examine the effect of land use using high-frequency sensors placed in six streams. Three streams draining predominantly grassland (>80%) and three streams draining cropland (>80%) watersheds. Sensors were installed in March and removed in December, allowing us to examine annual seasonal dynamics in addition to land use effects. We predict that in cropland draining watersheds there will be higher GPP and ER than grassland watersheds. Understanding the connections between land use and stream metabolism may help us better manage aquatic resources.
