Manipulation of Farmed Wetlands Increases use by Migrating Shorebirds and Ducks Open
The Drift Prairie, in central North America, has been largely converted from grasslands to croplands, but still contains thousands of wetlands used by shorebirds and waterfowl during breeding and migration periods. Consequently, many of th…

Evaluating Fecal DNA Metabarcoding to Estimate the Dietary Botanical Composition of Goats Open
Improved techniques are needed to estimate the dietary species composition of grazing animals. The fecal DNA metabarcoding technique has been proposed as a noninvasive method to determine dietary species composition. However, studies sugge…

Invasive Species Change Plant Community Composition of Preserved Prairie Pothole Wetlands Open
Plant communities in North American prairie pothole wetlands vary depending on hydrology, salinity, and anthropogenic disturbance in and around the wetland. We assessed prairie pothole conditions on United States Fish and Wildlife Service …

Plant blindness represents the loss of generational knowledge and cultural identity Open
Plant blindness, the inability of people to notice plants, is of current interest in the natural sciences community. It has been hypothesized that communities of varying cultures may have improved plant sight. Researchers used an online su…

Using a vegetation index to assess wetland condition in the Prairie Pothole Region of North America Open
Wetlands deliver a suite of ecosystem services to society. Anthropogenic activities, such as wetland drainage, have resulted in considerable wetland loss and degradation, diminishing the intrinsic value of wetland ecosystems worldwide. Pro…

Impacts and Drivers of Smooth Brome (Bromus inermis Leyss.) Invasion in Native Ecosystems Open
Smooth brome (Bromus inermis Leyss.) is an invasive cool-season grass that has spread throughout the Great Plains of North America. The species is considered one of the most widespread exotic grasses that has successfully invaded both cool…

Kentucky Bluegrass Invasion in the Northern Great Plains and Prospective Management Approaches to Mitigate Its Spread Open
Kentucky bluegrass (Poa pratensis L.) is one of the most aggressive grasses invading Northern Great Plains (NGP) grasslands, resulting in substantial native species losses. Highly diverse grasslands dominated by native species are graduall…

Upland burning and grazing as strategies to offset climate-change effects on wetlands Open
Wetland ecosystems perform a multitude of services valued by society and provide critical habitat for migratory birds and other wildlife. Despite their importance, wetlands have been lost to different local, regional, and global drivers. R…

Typha (Cattail) Invasion in North American Wetlands: Biology, Regional Problems, Impacts, Ecosystem Services, and Management Open
Typha is an iconic wetland plant found worldwide. Hybridization and anthropogenic disturbances have resulted in large increases in Typha abundance in wetland ecosystems throughout North America at a cost to native floral and faunal biodive…

EDGES AND RUSHES OF MINNESOTA: THE COMPLETEGUIDETOSPECIESIDENTIFICATION. Welby R. Smith; photography by Richard Haug. Open
Even the most seasoned individual with a plant identification background can relate to the difficulty of identifying sedges and rushes to the species level. Historically, one has had to rely on dichotomous keys to identify a sedge or rush …

Targeting Introduced Species to Improve Plant Community Composition on USFWS-Managed Prairie Remnants Open
The quality of plant community composition on US Fish and Wildlife Service (USFWS) lands in North Dakota and South Dakota has declined over the past several decades—the abundance of native species has decreased while the abundance of intro…

Geographically Isolated Wetlands: Rethinking a Misnomer Open
We explore the category “geographically isolated wetlands” (GIWs; i.e., wetlands completely surrounded by uplands at the local scale) as used in the wetland sciences. As currently used, the GIW category (1) hampers scientific efforts by ob…
