Upper Midwest Environmental Sciences Center

Our Upper Midwest Environmental Sciences Center's priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community. The Center is open with operations adjusted based on guidance from the Safer Federal Workforce Task Force and federal policies and informed by local community transmission level.

Global patterns of allochthony in stream–riparian meta-ecosystems

Ecosystems that are coupled by reciprocal flows of energy and nutrient subsidies can be viewed as a single “meta-ecosystem.” Despite these connections, the reciprocal flow of subsidies is greatly asymmetrical and seasonally pulsed. Here, we synthesize existing literature on stream–riparian meta-ecosystems to quantify global patterns of the amount of subsidy consumption by organisms, known as “allo

Deep learning workflow to support in-flight processing of digital aerial imagery for wildlife population surveys

Deep learning shows promise for automating detection and classification of wildlife from digital aerial imagery to support cost-efficient remote sensing solutions for wildlife population monitoring. To support in-flight orthorectification and machine learning processing to detect and classify wildlife from imagery in near real-time, we evaluated deep learning methods that address hardware limitati

Controls on in-stream nitrogen loss in western Lake Erie tributaries

Management efforts to reduce cyanobacterial harmful algal blooms (cHABs) in the Great Lakes have focused on decreasing tributary inputs of phosphorus (P). Recent research has indicated that reduction of both P and nitrogen (N) can lessen cHABs severity. Microbially mediated N cycling in streambed sediment may reduce N riverine loads, yet little is known about in-stream N processing rates in the Ma

Genetic control of Grass Carp through RNA interface

Grass Carp are one of the Invasive Carp species monitored by the Minnesota Department of Natural Resources in the Upper Mississippi River, navigation pools 1-8. Grass Carp are herbivores that feed heavily on vegetation and have been found to damage and even irradicate aquatic vegetation communities vital to many native fish and waterfowl species. Loss of aquatic vegetation can also disrupt food...

Deployment and Evaluation of an Underwater Acoustic Deterrent System at Lock and Dam 19

Previous studies and experience have demonstrated that some locks and dams operate as bottlenecks or pinch points for invasive carp populations and range expansion because of unique hydraulic conditions and operations at these dams. As compared to dams without these unique conditions, pinch-point dams restrict upstream fish passage to the lock chamber and result in limited (but not zero) upstream...

Invasive Carp Control: Acoustic Deterrents

Invasive carp including bighead carp ( Hypophthalmichthys nobilis) , silver carp ( H. molitrix ), grass carp ( Ctenopharyngodon idella ), and black carp ( Mylopharyngodon piceus ) are invasive fish species established in the Mississippi and Ohio River basins. The spread of these species threatens the Laurentian Great Lakes and other major waterways. Significant work has been done to identify...
