Primary production (PP), nutrient uptake, and carbon (C) cycling within epilithic biofilm communities were assessed in four headwater streams in the Arkansas Ozarks, U.S.A., representing a hundred-fol...
Effects of seasonality and resource limitation on organic matter turnover by Chironomidae (Diptera) in southern Appalachian headwater streams
seasonality resource limitation Chironomidae in southern Appalachian headwater streams
2014/4/17
Despite their high abundance, secondary production, and known reliance on detrital material, the role of chironomids (Diptera) in fine particulate organic matter (FPOM) dynamics has not been well quan...
