Background Since the late 1990s,bigheaded carps(largely silver carp[Hypophthalmichthys molitrix]but also bighead carp[H.nobilis])have established throughout the lower Mississippi River basin.Using previously studied o...
The economic damage to soybean [Glycine max (L.) Merr.] production in the United States attributed to nematodes has increased in recent years. Understanding how soil properties affect nematodes will help to properly m...
Manure management is an essential component of dairy production. Nutrient-laden, field-applied dairy manure often serves as a fertilizer source, but can also pose environmental threats if not properly managed. The Haa...
Well-aggregated soil has been shown to improve soil infiltration and reduce runoff and soil erosion, making well-aggregated soil important for productive, sustainable agriculture. One factor that may influence near-su...
Detailed topographic map drainage system and erosional landform evidence such as drainage route orientations, drainage divides, divide crossings (low points on drainage divides), erosional escarpments, and similar fea...
A new Cenozoic geology and glacial history paradigm (new paradigm), fundamentally different from the accepted Cenozoic geology and glacial history paradigm (accepted paradigm), describes a thick North American contine...
United States Geological Survey (USGS) topographic maps (available at the USGS National Map website) are used to determine development of the asymmetric South Platte River drainage basin (south of Denver) by noting lo...
This study was supported by the Slime Mold Project at the University of Arkansas and by project 570-B8-006;the Vicerrectoría de Investigación at Universidad de Costa Rica.
Samples of dead leaves on the forest floor were collected from a locality in central Costa Rica and another locality in northwest Arkansas in the United States and then were placed in fine-mesh nylon bags,autoclaved a...
