Quantifying nutrient retention and transformation in rivermouths- James Larson

Rivermouths and other areas of the Great Lakes nearshore zone are the interface between the Lakes and the human communities that surround them. These areas provide abundant ecosystem services, including those related to provisioning services (food and water supply), cultural services (recreation and tourism) and regulating services (water quality regulation).

Estimating trends in river and stream water temperature using improved statistical models- Bryan Gray

Interest in the effects of climate change will continue to spur efforts to model changes in river and stream temperatures. Such changes may have important effects on aquatic organisms. A challenge is that statistical efforts should not rely on standard linear models when water temperatures span intermediate values and either low or high values (<5 °C or >25 °C). ...

Evaluating potential ecosystem indicators of Great Lakes restoration success- James Larson

One of the focus areas for the Great Lakes Restoration Initiative's (GLRI) Action Plan is to implement a science-based adaptive management approach. Here, we propose to monitor ecosystem processes across the Great Lakes to identify ecosystem response to local and watershed-wide restoration activities. ...

Monitoring and predicting the impacts of trees on urban stormwater volume reduction

Much has been learned about how effectively individual green infrastructure practices can reduce stormwater volume, however, the role of urban trees in stormwater detention is poorly understood. This study will quantify the effect of tree removal on the urban hydrologic cycle and measure the impact that trees have on stormwater runoff volume.

Amphibian Population Dynamic Models for Decision Making- Robin Russell

Amphibians are among the most threatened vertebrate taxa worldwide, and are facing a suite of potential stressors. In a recent synthesis, researchers identified four major threats - land use change, disease risk, climate change, and pesticide use - contributed to the local extinction of amphibian populations, but the strength and direction of these effects varied geographically.

Using optical sensors to detect sewage contamination in the Great Lakes

In the Great Lakes, large volumes of sewage never make it to wastewater treatment plants due to illicit discharges and leaking sewer infrastructure, but contamination can be difficult to detect. This study will define the utility and practicality of using optical sensors to identify the sources and timing of sewage contamination in surface water and storm sewers in real-time field settings....

Bird Banding Laboratory

The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America.  This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

Mining and Energy

Scientists are examining a number of issues to characterize potential effects of unconventional oil and gas development in the Bakken Shale within the Williston Basin, located in ND, SD and MT. Research is building upon current/ongoing studies to implement new, innovative research including water quality, water availability, ecological effects, proppant sand, and induced seismicity.

Flood Response

Floods are the leading cause of natural disaster losses, and Midwest Region scientists are ready to respond. Flood inundation maps tied to USGS real-time stream gage data and National Weather Service flood forecast sites enable state and local communities to make timely operational and public safety decisions during floods.

Using leaf collection and street cleaning to reduce nutrients in urban stormwater

Decaying organic materials, like leaf litter, can release excess nutrients into local streams and lakes, causing eutrophication and algal blooms. To determine if a municipal leaf collection and street cleaning program can reduce nutrients in stormwater runoff, the USGS measured phosphorus and nitrogen in stormwater from residential areas in Madison, Wis.

Correlating seasonal trends and occupancy of bigheaded carp eDNA to land use and stream characteristics

The results of this study will advance our understanding of environmental DNA (eDNA) and how eDNA signatures change as fish behavior changes over the course of the open water season.  This will further develop eDNA as an easy sampling method to collect information about invading populations or cryptic species that are difficult to capture so that resource managers can be given better...
