Rui: The Role Of Dissolved Organic Material In Regulating Primary Production In Prairie Saline Lakes, Jasmine E. Saros

University of Maine Office of Research Administration: Grant Reports

Grasslands and converted grasslands (i.e. agricultural land) cover extensive areas in semi-arid regions of the world. Lakes situated in grasslands are usually saline and have high concentrations of dissolved organic matter (DOM). We hypothesize that DOM plays a critical role in regulating algal production in prairie saline lakes by binding nutrients and making them less available to algae. To explore this hypothesis, we will survey a suite of chemical and biological parameters in lakes from three areas in the central and northern Great Plains (ND, SD, NE). A series of experiments will be conducted in Years 2 and 3 to …
