Prairie streams are a valued ecosystem that dominates the mid-continental United States from the Canadian border to the southernmost States. The Prairie Streams and Fishes Collaborative (PSFC) is a geographically diverse group of f isheries professionals who share an interest in prairie streams and associated prairie stream fishes. 

Spotted skunks (Spilogale spp.) were historically widespread across much of North America, but long-term harvest trends and anecdotal evidence suggested notable population declines, leading to a petition to list the plains spotted skunk (S. interrupta) under the Endangered Species Act.

Donovan Maude, University of Idaho graduate student, capturing white sturgeon (Acipenser transmontanus), Snake River, Idaho. White Sturgeon is an important species, unfortunately, little is known about their population ecology and whether current monitoring metrics are adequate for evaluating management and conservation success. We are working with the U.S.

Tufted puffins are an iconic species in the Pacific Northwest that provide a wide range of ecological, economic, and historically important services such as ecotourism for local communities- and bringing marine derived nutrients to terrestrial habitats.

Nine-banded armadillos—the only armadillo species found in the United States—are distributed widely across southern states.

USGS researchers from the Michigan Cooperative Fish and Wildlife Research Unit have found that the nine-banded armadillo has expanded its range to cover all of Missouri, southern Iowa, parts of Kansas and Illinois, northern and eastern Indiana, eastern Kentucky and Tennessee, and nearly all of South Carolina and Georgia, as well as the western third of North Carolin

Mesopredators play important ecological roles in most systems. This group of wildlife is often well-adapted to human development and their densities can vary according to the human-subsidized resources with trickle down effects on other animals.

Little is understood about the behavior, location, and habitat preferences of juvenile Gulf sturgeon. To learn more about this prehistoric fish, the Florida Cooperative Fish and Wildlife Research Unit at the University of Florida, the National Oceanic and Atmospheric Administration, and the U.S.
