Chemistry and Biochemistry Faculty Publications

An analytical method utilizing chemical ionization gas chromatography-mass spectrometry was developed for the simultaneous determination of cyanide and thiocyanate in plasma. Sample preparation for this analysis required essentially one-step by combining the reaction of cyanide and thiocyanate with pentafluorobenzyl bromide and simultaneous extraction of the product into ethyl acetate facilitated by a phase-transfer catalyst, tetrabutylammonium sulfate. The limits of detection for cyanide and thiocyanate were 1 μM and 50 nM, respectively. The linear dynamic range was from 10 μM to 20 mM for cyanide and from 500 nM to 200 μM for thiocyanate with correlation coefficients higher than 0.999 for …

Knowledge of environmental factors influencing demography of weed species will improve understanding of current and future weed invasions. The objective of this study was to quantify regional-scale variation in vital rates of giant ragweed and common sunflower. To accomplish this objective, a common field experiment was conducted across seven sites between 2006 and 2008 throughout the north central U.S. maize belt. Demographic parameters of both weed species were measured in intra- and interspecific competitive environments, and environmental data were collected within site-years. Site was the strongest predictor of belowground vital rates (summer and winter seed survival and seedling recruitment), indicating …

Chemistry and Biochemistry Faculty Publications

Routine antigenic characterization of swine influenza virus isolates in a high-throughput serum neutralization (HTSN) assay found that approximately 20% of isolates were not neutralized by a panel of reference antisera. Genetic analysis revealed that nearly all of the neutralization-resistant isolates possessed a seasonal human-lineage hemagglutinin (HA; δ cluster). Subsequent sequencing analysis of full-length HA identified a conserved N144 residue present only in neutralization-resistant strains. N144 lies in a predicted N-linked glycosylation consensus sequence, i.e., N-X-S/T (where X is any amino acid except for proline). Interestingly, neutralization-sensitive viruses all had predicted N-linked glycosylation sites at N137 or N142, with threonine (T) …

Foraging Ecology Of Fall-Migrating Shorebirds In The Illinois River Valley, Randolph V. Smith, Joshua Stafford, Aaron P. Yetter, Michelle M. Horath, Christopher S. Hine, Jeffery P. Hover

Natural Resource Management Faculty Publications

Populations of many shorebird species appear to be declining in North America, and food resources at stopover habitats may limit migratory bird populations. We investigated body condition of, and foraging habitat and diet selection by 4 species of shorebirds in the central Illinois River valley during fall migrations 2007 and 2008 (Killdeer [Charadrius vociferus], Least Sandpiper [Calidris minutilla], Pectoral Sandpiper [Calidris melanotos], and Lesser Yellowlegs [Tringa flavipes]). All species except Killdeer were in good to excellent condition, based on size-corrected body mass and fat scores. Shorebird diets were dominated by invertebrate taxa from Orders Diptera and Coleoptera. Additionally, Isopoda, Hemiptera, …

Alternative Annual Forage Crop Options For Northern Great Plains Cattle Producers: A South Dakota Case Study, Md Parvez, Scott Fausti, Thandiwe Nleya, Patricia Johnson, Kenneth Olsen, John Rickertsen Aug 2012

Alternative Annual Forage Crop Options For Northern Great Plains Cattle Producers: A South Dakota Case Study, Md Parvez, Scott Fausti, Thandiwe Nleya, Patricia Johnson, Kenneth Olsen, John Rickertsen

Economics Staff Paper Series (1969 - 2017)

In the Northern Great Plains region, crop and livestock producers view forage crop production as an important component of their farm management system. During periods of increased environmental risk, alternative annual forage crops may provide producers with a risk reducing alternative to traditional forage crops. An alternative forage crop production study (20 varieties) was conducted by South Dakota State University. Production yield data was analyzed using alternative decision making criteria when outcomes are uncertain. Empirical results provide insight on forage crop planting decisions with respect to the importance of optimal harvest timing, and the ranking of alternative forage crops as …

Risk And Marketing Behavior: Pricing Fed Cattle On A Grid, Scott Fausti, Zhiguang Wang, Beshir Qasmi, Matthew A. Diersen Jul 2012

Risk And Marketing Behavior: Pricing Fed Cattle On A Grid, Scott Fausti, Zhiguang Wang, Beshir Qasmi, Matthew A. Diersen

Economics Staff Paper Series (1969 - 2017)

A seven year comparative study of grid pricing versus average pricing of slaughter cattle was conducted to evaluate carcass quality market signals. The primary objective of the study is to determine if market signals sent through the grid pricing system are encouraging producers to market on a grid and discouraging them to market by the pen. Two secondary objectives investigate: 1) if price risk associated with carcass quality uncertainty affects marketing decisions, and 2) if a change in price risk (volatility) affects producer marketing decisions. An EARCH-ln-Mean modeling procedure was adopted. Empirical results suggest that the grid premium and discount …


Survival Of White-Tailed Deer Fawns In The Grasslands Of The Northern Great Plains, Troy W. Grovenburg, Robert W. Klaver, Jonathan A. Jenks Jul 2012

Survival Of White-Tailed Deer Fawns In The Grasslands Of The Northern Great Plains, Troy W. Grovenburg, Robert W. Klaver, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Environmental factors, such as forest characteristics, have been linked to fawn survival in eastern and southern white-tailed deer ( Odocoileus virginianus) populations. In the Great Plains, less is known about how intrinsic and habitat factors influence fawn survival. During 2007-2009, we captured and radiocollared 81 fawns in north-central South Dakota and recorded 23 mortalities, of which 18 died before 1 September. Predation accounted for 52.2% of mortality; remaining mortality included human (hunting, vehicle, and farm accident; 26.1%) and hypothermia (21.7%). Coyotes (Canis latrans) accounted for 83.3% of predation on fawns. We used known-fate analysis in Program MARK to estimate summer …

Chemistry and Biochemistry Faculty Publications

2-Aminothiazoline-4-carboxylic acid (ATCA) was intravenously injected to rats in order to investigate its plasma distribution. ATCA was extracted from plasma samples by solid phase extraction (SPE) and molecularly imprinted polymer stir bar sorption extraction (MIP-SBSE). Detection and quantification of ATCA were achieved by using liquid chromatography–tandem mass spectrometry (LC–MS/MS). It was found that the intravenously injected ATCA concentration quickly decreased to half within 2.5 h in the rat system. However, after 2.5 h, the concentration of ATCA in plasma stayed constant at least 5 folds above the endogenous ATCA level for more then 48 h. This finding can be used …

Veterinary and Biomedical Sciences Faculty Publications

Porcine reproductive and respiratory syndrome (PRRS) is one of the most devastating and costly diseases to the swine industry worldwide. Overall, the adaptive immune response to PRRS virus (PRRSV) is weak, which results in delayed elimination of virus from the host and inferior vaccine protection. PRRSV has been shown to induce a meager alpha interferon (IFN-α) response, and we hypothesized that elevated IFN-α levels early in infection would shorten the induction time and increase elements of the adaptive immune response. To test this, we measured both antibody and cell-mediated immunity in pigs after the administration of a nonreplicating human adenovirus …

Natural Resource Management Faculty Publications

Epizootic pneumonia of bighorn sheep is a devastating disease of uncertain etiology. To help clarify the etiology, we used culture and culture-independent methods to compare the prevalence of the bacterial respiratory pathogens Mannheimia haemolytica, Bibersteinia trehalosi, Pasteurella multocida, and Mycoplasma ovipneumoniae in lung tissue from 44 bighorn sheep from herds affected by 8 outbreaks in the western United States. M. ovipneumoniae, the only agent detected at signifi cantly higher prevalence in animals from outbreaks (95%) than in animals from unaffected healthy populations (0%), was the most consistently detected agent and the only agent that exhibited single strain types within each …


Spatial Ecology Of White-Tailed Deer Fawns In The Northern Great Plains: Implications Of Loss Of Conservation Reserve Program Grasslands, Troy W. Grovenburg, Robert W. Klaver, Jonathan A. Jenks Mar 2012

Spatial Ecology Of White-Tailed Deer Fawns In The Northern Great Plains: Implications Of Loss Of Conservation Reserve Program Grasslands, Troy W. Grovenburg, Robert W. Klaver, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Few studies have evaluated how wildlife, and white-tailed deer (Odocoileus virginianus) in particular, respond to Conservation Reserve Program (CRP) grasslands. We conducted a 3-year study (2007– 2009) to determine the influence of CRP on fawn ecology during a time of declining CRP enrollment. We captured and radiocollared 81 fawn white-tailed deer during 15 May to 15 June 2007–2009 in north-central South Dakota, collected 6,505 locations, and documented 70 summer home ranges. Mean summer home ranges increased temporally during 2007–2009 (P < 0.001) and corresponded to a 41% loss of CRP grasslands in the area (2.3% loss in land cover and approx. 21% loss in cover habitat in the study area) over the duration of the study. Additionally, mean movement between daily locations increased (P < 0.001) from 2007 to 2009. Analysis of covariance models indicated that change in CRP influenced home-range size, and change in CRP and wheat influenced daily movement. Smaller home ranges and reduced movements were associated with greater quantity of CRP available to fawns, and increased movements were associated with more acreage of wheat available to fawns. Fawns shifted resource selection during the summer at a mean age ranging from 48.8 days to 58.6 days, and this shift was associated with height of corn (83–87 cm). During early summer, fawns consistently selected for CRP; selection of wheat progressed temporally from avoidance in 2007 to selection in 2009. During late summer, fawns consistently selected for corn habitat and used CRP at least in proportion to its availability. Reduction in CRP-grasslands seemed to increase fawn home-range size and daily movements and, influenced change in resource selection to wheat. Current legislation mandates continued decrease in CRP enrollment and concomitant increase in the planting of corn for ethanol production. Management of habitat throughout the grasslands of the Northern Great Plains that maximizes cover habitats would provide neonates with adequate cover for protection from predators.

Veterinary and Biomedical Sciences Faculty Publications

For effective disease surveillance, rapid and sensitive assays are needed to detect antibodies developed in response to porcine reproductive and respiratory syndrome virus (PRRSV) infection. In this study, we developed a multiplexed fluorescent microsphere immunoassay (FMIA) for detection of PRRSV-specific antibodies in oral fluid and serum samples. Recombinant nucleocapsid protein (N) and nonstructural protein 7 (nsp7) from both PRRSV genotypes (type I and type II) were used as antigens and covalently coupled to Luminex fluorescent microspheres. Based on an evaluation of 488 oral fluid samples with known serostatus, the oral fluid-based FMIAs achieved >92% sensitivity and 91% specificity. For serum …


Hierarchy In Factors Affecting Fish Biodiversity In Floodplain Lakes Of The Mississippi Alluvial Valley, Daniel J. Dembkowski, L. E. Miranda Feb 2012

Hierarchy In Factors Affecting Fish Biodiversity In Floodplain Lakes Of The Mississippi Alluvial Valley, Daniel J. Dembkowski, L. E. Miranda

Natural Resource Management Faculty Publications

River-floodplain ecosystems offer some of the most diverse and dynamic environments in the world. Accordingly, floodplain habitats harbor diverse fish assemblages. Fish biodiversity in floodplain lakes may be influenced by multiple variables operating on disparate scales, and these variables may exhibit a hierarchical organization depending on whether one variable governs another. In this study, we examined the interaction between primary variables descriptive of floodplain lake large-scale features, suites of secondary variables descriptive of water quality and primary productivity, and a set of tertiary variables descriptive of fish biodiversity across a range of floodplain lakes in the Mississippi Alluvial Valley of …
