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.

Introduction and methods of analysis for peak streamflow trends and their relation to changes in climate in Illinois, Iowa, Michigan, Minnesota, Missouri, Montana, North Dakota, South Dakota, and Wisconsin

Flood-frequency analysis, also called peak-flow frequency or flood-flow frequency analysis, is essential to water resources management applications including critical structure design and floodplain mapping. Federal guidelines for doing flood-frequency analyses are presented in a U.S. Geological Survey Techniques and Methods Report known as Bulletin 17C. A basic assumption within Bulletin 17C is t

Non-negligible near-term risk of extinction to the eastern migratory population of monarch butterflies—An updated assessment (2006–22)

The eastern migratory population of monarch butterflies (Danaus plexippus) started declining as early as the mid-1970s and seemed to stop declining by the early 2000s; the population now (about 2022) persists at a much-reduced abundance. Stochastic variation in abundance, at levels typical of monarch butterflies and other insects, was assessed to determine whether this population is at heightened

Using a coupled integral projection model to investigate interspecific competition during an invasion: An application to silver carp (Hypophthalmichthys molitrix) and gizzard shad (Dorosoma cepedianum)

As a generalization of stage-based matrix models, integral projection models (IPMs) have been used to describe the size-based dynamics of wildlife and fisheries populations. Although some matrix models have explicitly included species interactions, few IPMs have expanded beyond single species, which limits their ability to describe the competitive dynamics of co-occuring taxa. We present a coupled

Aquatic Vegetation Monitoring

The Mississippi River is of global importance to persons and to the wildlife that live on and migrate along the river corridor. Data collected and processed by the Long-Term Resource Monitoring (LTRM) element of the Upper Mississippi River Restoration (UMRR) Program serves to help us understand, restore, and protect this remarkable ecosystem. The LTRM has collected aquatic and floodplain...

25 Years of Change in Aquatic Plants in the Upper Mississippi River

The Upper Mississippi River, along with a few other rivers worldwide, has experienced a remarkable increase in aquatic vegetation over the last 25 years. Using complex community modeling, scientists are determing where, what species, and why, aquatic vegetation increases were observed in the Mississippi River. This information can help us understand the natural recovery of aquatic plants, and how...

Identifying Ecosystem States of the Upper Mississippi River

Ecosystem states are bundles of biological and physical characteristics that occur regularly in a habitat. They are used to help understand ecosystems and to communicate which state conditions are desirable or unhealthy. Scientists hypothesized that there are several different ecosystem states in the Mississippi river, with one of them being the best for waterfowl, and therefore a desirable goal...
