Pennycress reduces potential for nutrient loss in Illinois Open
Nutrient export of nitrogen and phosphorus from row crop agriculture in the Upper US Midwest is a threat to the structure and function of aquatic systems. To meet Environmental Protection Agency (EPA) nutrient reduction goals, the Upper US…

Cover crop species influences soil fungal species richness and community structure Open
Despite the well documented link between cover cropping and soil microbiology, the influence of specific cover crop species on soil microbes remains poorly understood. We evaluated how soil fungal communities in a no till system respond to…

Flies associated with floral canopies of the new oilseed crop, pennycress, in the Midwestern U.S.A. Open
Flies are frequent visitors to flowers of many species of plants within the mustard family (Brassicaceae). They derive nutrition from these flowers, and some fly species are pollinators. Field pennycress (Thlaspi arvense) is a mustard spec…

Abundance and diversity of bees visiting flowering pennycress, a new oilseed crop in the midwestern USA Open
Oilseed pennycress (Thlaspi arvense) is a new, autumn-sown, “cash cover crop” for the Midwestern USA and elsewhere. Anthesis occurs in early spring when few other plants bloom, and its flowers attract early-emerging bees. However, the taxo…

Biomass, nitrogen, and carbon loss from the novel oilseed pennycress relative to annual ryegrass and cereal rye Open
The rate of pennycress residue decomposition and mineralization is critical in determining potential nutrient availability for following crops. To better understand pennycress decomposition, we examined biomass, nitrogen, and carbon loss f…

Method for producing metallic microparticles Open
Method for producing metallic particles. The method converts metallic nanoparticles into larger, spherical metallic particles. An aerosol of solid metallic nanoparticles and a non-oxidizing plasma having a portion sufficiently hot to melt …

Method for producing carbon nanotubes Open
Method for producing carbon nanotubes. Carbon nanotubes were prepared using a low power, atmospheric pressure, microwave-generated plasma torch system. After generating carbon monoxide microwave plasma, a flow of carbon monoxide was direct…

Loss of Ice Cover, Shifting Phenology, and More Extreme Events in Northern Hemisphere Lakes Open
Long‐term lake ice phenological records from around the Northern Hemisphere provide unique sensitive indicators of climatic variations, even prior to the existence of physical meteorological measurement stations. Here, we updated ice pheno…

Microplastic prevalence in two fish species in two U.S. reservoirs Open
Microplastics in the environment can impact feeding and physiological functions of organisms. Most studies have focused on marine systems, and studies of lacustrine organisms are less common. We examined microplastic concentration in 72 gi…

Effects of elevated water velocity on the invasive rusty crayfish (Orconectes rusticus Girard, 1852) in a laboratory mesocosm Open
Invasions of the rusty crayfish Orconectes rusticus (Girard, 1852) in lakes have led to the local extirpation of resident crayfishes and altered littoral communities. The spread of O. rusticus into streams poses an equally serious threat t…

Adeno-Associated Virus (AAV) as a Vector for Gene Therapy Open
There has been a resurgence in gene therapy efforts that is partly fueled by the identification and understanding of new gene delivery vectors. Adeno-associated virus (AAV) is a non-enveloped virus that can be engineered to deliver DNA to …

Increased salinity affects survival and osmotic response of rusty crayfish Orconectes rusticus Girard, 1852 and northern clearwater crayfish O. propinquus Girard, 1852 (Decapoda: Astacoidea: Cambaridae) as salinity increases: the potential for estuarine invasions Open
The potential colonization of the rusty crayfish, Orconectes rusticus (Girard, 1852), has previously focused on lakes and streams of northeastern United States and southeastern Canada, but estuaries have not been considered. Rusty crayfish…

Changes in Water-Extractable Organic Carbon with Cover Crop Planting under Continuous Corn Silage Production Open
Long-term row crop agricultural production has dramatically reduced the pool of soil organic carbon. The implementation of cover crops in Midwestern agroecosystems is primarily to reduce losses of nitrogenous fertilizers, but has also been…
