Rebecca M Kreiling, PhD
Becky is an aquatic ecologist who has worked for the Upper Midwest Environmental Sciences Center since 2005.
My research interests include understanding how nutrient cycling in aquatic ecosystems influences nutrient concentrations and delivery to downstream waterbodies and providing managers with information to improve water quality and restore habitat. I conduct research across a range of aquatic ecosystems from small, isolated wetlands to large rivers and their floodplains.

Climate-Driven Connectivity Between Prairie-Pothole and Riparian Wetlands in the Upper Mississippi River Watershed: Implications for Wildlife Habitat and Water Quality
Wetland conservation in the Upper Mississippi River Basin (UMRB) is a priority for Federal, State, NGO, and Tribal land managers to support migratory bird habitat in Minnesota and Iowa. These wetlands, known as depressional wetlands, also provide ecosystem services associated with flood water storage and enhancing down-stream water quality by storing and processing nutrients. Understanding how con
Nutrient cycling in agricultural watersheds of the Great Lakes
Nutrients lost from agricultural areas in watersheds of the Great Lakes cause harmful algal blooms and hypoxia in some areas of the Great Lakes. Substantial efforts are being made in these watersheds to reduce the amount of nutrients entering the streams and rivers; however, additional work is needed to further reduce nutrient loads to meet international water quality standards. Limited research...
Nutrient Cycling in Aquatic Ecosystems
Nitrogen and phosphorus are plant essential nutrients that are currently in excess in many aquatic ecosystems due to runoff from urban and agricultural areas. In high amounts, these nutrients are detrimental to aquatic ecosystem health, because elevated nutrients promote excessive growth or “blooms” of algae and other nuisance species. Many species that cause blooms can produce toxins which are...
Nutrient retention on the Upper Mississippi River Floodplain
Rivers have a natural capacity to improve water quality when they are connected to their natural floodplains and are not overloaded with sediment and nutrient runoff. Where rivers have been disconnected from their historical floodplains and channelized to eliminate backwater areas, increased flow and nutrient loads have contributed to local and downstream problems of excessive nutrient enrichment...
HABs: Characterizing Zones of High Potential Nutrient Cycling in Agricultural Catchments
River sediments have the capacity to remove nutrients from the water column which lowers the nutrient load to downstream water bodies. The objectives of this project were to characterize rates of sediment nitrogen removal and phosphorus retention in river networks draining agricultural watersheds and to assess how land use and land management actions affect these rates. This information is helpful...
