Small- And Medium-Sized Feedlots: Management And Marketing Survey Results, Matthew A. Diersen, Scott W. Fausti

Economics Research Reports

Increasing sector specialization has led to a decline in the number of smaller feedlots in the U.S. However, some operations continue to finish or background cattle as part of diversified operations. After a set of focus group sessions a survey was conducted of feedlots in South Dakota to determine the competitive tradeoffs among size of operation and production and risk management practices. The mail survey was designed in collaboration with the National Agricultural Statistical Service (NASS). NASS designed a stratified random sampling methodology for survey instrument dissemination. A bi-variate sampling stratification procedure was used; South Dakota feedlots with less than …

Weed Establishment And Persistence After Water Pipeline Installation And Reclamation In The Mixed Grass Prairie Of Western North Dakota, Erin K. Espeland, Lora B. Perkins

Natural Resource Management Faculty Publications

Weeds in reclamations interfere with success by: 1) competing with desirable species seeded during revegetation; 2) preventing recolonization of reclamations by native species; and 3) reducing the integrity of landscapes by expanding from reclamations into adjacent, intact areas. In the Bakken oilfield of western North Dakota, dispersed reclamation activity and increased traffic may provide many opportunities for weeds to spread. To determine the potential for disturbance and reclamation to increase resident weed populations and introduce new weed species, we tracked twenty-one weed (non-native/ruderal/invasive) species over a four-year period after the installation of a 1.8 km livestock water pipeline and subsequent …

Cochrane-based criteria adherent, peer-reviewed study designs conducted and published in the English language from 1950 to 2014 were collected in 2015, analyzed in 2016, and used to evaluate the effect of nutrition labeling on calories and nutrients ordered or consumed. Before and after menu labeling outcomes were used to determine weighted mean differences in calories, saturated fat, total fat, carbohydrate, and sodium ordered/consumed which were pooled across studies using random effects modeling. Stratified analysis for …

Land Surface Phenology And Seasonality Using Cool Earthlight In Croplands Of Eastern Africa And The Linkages To Crop Production, Woubet G. Alemu, Geoffrey M. Henebry

GSCE Faculty Publications

Across Eastern Africa, croplands cover 45 million ha. The regional economy is heavily dependent on small holder traditional rain-fed peasant agriculture (up to 90%), which is vulnerable to extreme weather events such as drought and floods that leads to food insecurity. Agricultural production in the region is moisture limited. Weather station data are scarce and access is limited, while optical satellite data are obscured by heavy clouds limiting their value to study cropland dynamics. Here, we characterized cropland dynamics in Eastern Africa for 2003–2015 using precipitation data from Tropical Rainfall Measuring Mission (TRMM) and a passive microwave dataset of land …

Biomass Yield Of Switchgrass Cultivars Under High- Versus Low-Input Conditions, Michael D. Casler, Sergio Sosa, Lindsey Hoffman, Hilary Mayton, Calvin Ernst, Paul R. Adler, Arvid R. Boe, Stacy A. Bonos

Agronomy, Horticulture and Plant Science Faculty Publications

Switchgrass (Panicum virgatum L.) is undergoing development as a biomass crop to support conversion of cellulosic biomass to energy. To avoid the competition of biomass with food or feed crops, most commercialization proposals suggest that switchgrass should be grown exclusively on marginal lands that are not fit for food or feed production. The objective of this study was to investigate the potential for cultivar x environment interactions that would affect the methods and approaches for breeding and evaluating switchgrass cultivars, including both upland and lowland types, for high-input versus low-input types of environments. Biomass yield was measured on 14 cultivars …

Quantitative Analysis Of Endocytosis Of Macrophage Growth Factor Receptor By Molecular Imaging, Victor Georgiev, Emily Toering, Christopher Callahan

The Journal of Undergraduate Research

Endocytosis is a critical cellular process responsible for nutrient uptake, sampling the environment, and cellular signaling. Endocytosis of growth factor receptors is an important step in the regulation of receptor signaling functions. The macrophage growth factor receptor controls growth and differentiation of macrophages, however, the pathway by which the receptor is internalized is not well understood. The analysis showed that for the first time, knockout of endophilin A2 decreases the internalization of macrophage growth factor receptor in primary bone marrow macrophages. This shows that fast endophilin-mediated endocytosis plays a role in the control of the amount of growth factor receptors …

Fates Of Ovules In Groundplum Milk-Vetch (Astragalus Crassicarpus Nutt.) In South Dakota, Arvid Boe, Paul J. Johnson

Native Plant Focused Publications

Groundplum milk-vetch (Astragalus crassicarpus Nutt.) is a native legume found on gravelly to sandy prairie uplands throughout central North America. The large and fleshy fruits, or pods, of this species were consumed by indigenous people and European settlers, and are cached by rodents. Our previous research on native legumes of the northern Great Plains indicated seed predation by insects, notably bruchid beetles belonging to the genus Acanthoscelides Schilsky, was a dominant factor determining viable seed production in natural and artificial plant assemblages. However, although we have studied the reproductive biology of several species of Astragalus L., none had fleshy pods. …
