A Survey Of Aquatic Invertebrate Communities In Nebraska Sandhill Lakes Reveals Potential Alternative Ecosystem States, J.C. Jolley, E.S. Albin, M.A. Kaemingk, D.W. Willis

Natural Resource Management Faculty Publications

Aquatic invertebrate communities are important to shallow lake ecosystem form and function, providing vital components to the food web and thereby important to achieving lake management goals. We characterized lake invertebrate communities and physicochemical variables in six Nebraska Sandhill lakes and examined these characteristics within an alternative stable state framework. Surveys were conducted during 2005 within each of these lakes by sampling aquatic macroinvertebrate abundance, zooplankton abundance and biomass, phytoplankton biomass, and physicochemical variables. When placed within an alternative stable state framework, the response variables exhibited a gradient of different ecosystem states. Two lakes appeared congruent with the clear water …

Phenethylisothiocyanate Alters Site- And Promoter-Specific Histone Tail Modifications In Cancer Cells, Yi Liu, Suvobrata Chakravarty, Moul Dey

Chemistry and Biochemistry Faculty Publications

Site-specific histone modifications are important epigenetic regulators of gene expression. As deregulation of genes often results in complex disorders, corrective modulation of site-specific histone marks could be a powerful therapeutic or disease-preventive strategy. However, such modulation by dietary compounds and the resulting impact on disease risk remain relatively unexplored. Here we examined phenethylisothiocyanate (PEITC), a common dietary compound derived from cruciferous vegetables with known chemopreventive properties under experimental conditions, as a possible modulator of histone modifications in human colon cancer cells. The present study reports novel, dynamic, site-specific chemical changes to histone H3 in a gene-promoter-specific manner, associated with PEITC …

Migrating Mule Deer: Effects Of Anthropogenically Altered Landscapes, Patrick E. Lendrum, Charles R. Anderson Jr., Kevin L. Monteith, Jonathan A. Jenks, R. Terry Bowyer

Natural Resource Management Faculty Publications

Background: Migration is an adaptive strategy that enables animals to enhance resource availability and reduce risk of predation at a broad geographic scale. Ungulate migrations generally occur along traditional routes, many of which have been disrupted by anthropogenic disturbances. Spring migration in ungulates is of particular importance for conservation planning, because it is closely coupled with timing of parturition. The degree to which oil and gas development affects migratory patterns, and whether ungulate migration is sufficiently plastic to compensate for such changes, warrants additional study to better understand this critical conservation issue.
Methodology/Principal Findings: We studied timing and synchrony of …

Walking Distance And Performance Of Drylot Developed Beef Heifers Following Being Moved To A Grazing Situation, G.A. Perry, E.L. Larimore, J.A. Walker

South Dakota Beef Report, 2013

Research has shown that heifers moved from a drylot to grass after AI have decreased weight gains and pregnancy success compared to heifers developed on range. This effect could potentially be due to inexperience in a specific grazing environment, which could result in greater time spent exploring a new environment. In this study beef heifers were moved from a drylot to spring grass at two different times and their activity compared. Heifers in a drylot walked less than heifers grazing spring forage. However, following being moved to spring forage heifers that had been adjusted to grass for about a month …

The Effect Of Handler Personality Type On Feedlot Cattle Behavioral Responses, H. Franzky, R. Pritchard, J. Trenhaile

South Dakota Beef Report, 2013

The ability to readily identify individuals that may have a greater innate ability to handle cattle in a low stress manner would be useful in feedlots and on ranches. This study was conducted to determine whether handler personality type would be a useful tool to predict stockman abilities. To accomplish this, 3 cattle handling exercises were created to observe human‐cattle interactions. A scoring system was developed to investigate cattle handling proficiency based on cattle behavioral responses. Handler personality type was classified using two assessments. Some cattle handling exercises did not differentiate handler personality types. Introverted handlers tended to have higher …

Comparison Of Two Different Methods To Harvest Drought‐Damaged Corn, W.C. Rusche, J.A. Walker

South Dakota Beef Report, 2013

Two methods of harvesting drought‐stressed corn as large round bales were compared in this study. Three acres of drought‐stressed corn were cut and either baled as high‐moisture bales and wrapped in plastic (BALEAGE), or allowed to completely dry and baled with a conventional large round baler (DRY). Core samples were analyzed for moisture, CP, ADF, NDF and in vitro NDF and DM digestibility. Samples from the BALEAGE treatment were lower in CP than those from the DRY treatment. Concentrations of ADF and NDF did not differ between BALEAGE and DRY. Dry matter and NDF digestibility were also similar between the …

The Effect Of Freezing As A Storage Method On Anthocyanin Concentration In Blueberries, Marin E. Plumb

Undergraduate Honors Papers

Blueberries are rich in a water-soluble class of pigments known as anthocyanins which are known antioxidants. Antioxidants help prevent many diseases by stabilizing free radicals, but are prone to losses in food during storage. The goal of this study was to test the effect of freezing as a storage method on anthocyanin concentration and antioxidant activity over time. Blueberries from Canada and Argentina were frozen for up to 5 months and periodically tested for anthocyanin concentration and antioxidant activity. Anthocyanins were extracted using a mixture of methanol, acetic acid, and water, and evaporation under vacuum. They were separated using column …

The Influence Of Growth Stage On Carcass Compositionand Factors Associated With Marbling Development In Beef Cattle, S.A. Kern, R.H. Pritchard, S.M. Scramlin, B.P. Holland, A.D. Blair, K.R. Underwood

South Dakota Beef Report, 2013

There are many cellular regulatory factors that ultimately determine the intramuscular fat, or marbling content and quality of beef carcasses. Identifying factors which play a critical role in the development of intramuscular fat throughout the feeding period and determining how cattle feeders can manipulate these factors will be crucial to continue improving beef quality. Ideally, marbling must increase without excess accumulation of adipose in depots that are undesirable and economically detrimental (subcutaneous and visceral). The results of this study are novel as they show not only what cellular factors play a role in marbling development, but also how their expression …

The Influence Of Maternal Energy Status During Mid‐Gestationon Beef Offspring Carcass Characteristics And Meat Quality, D. A Mohrhauser, A.R. Taylor, K.R. Underwood, R.H. Pritchard, A.E. Wertz-Lutz, A.D. Weaver

South Dakota Beef Report, 2013

Research has suggested that maternal under‐nutrition may cause the development of a thrifty phenotype in the offspring, potentially resulting in greater adiposity and reduced muscle mass. These alterations in fat and muscle development could have lasting impacts on offspring growth, carcass characteristics, and meat quality. Thus, the objective of this study was to determine the influence of maternal energy status during mid‐gestation on offspring carcass characteristics and meat quality. To alter maternal energy status, cows either grazed pasture or were fed in a dry‐lot at 80% of the energy requirements for body weight maintenance during a mean period of 109 …

Impacts Of Land Cover Changes On Ecosystem Services Delivery In The Black Hills Ecoregion From 1950 To 2010, Suzanne Cotillon

Electronic Theses and Dissertations

Environmental degradation generated by land use choices and human activities is the first driver of change in the provision of ecosystem goods and services. One of the challenges in ecosystem services research is to evaluate the contribution of each land cover unit to ecosystem services delivery while considering multiple services. In this thesis, I develop a framework to assess the capacity of many land covers to independently produce ecosystem services (i.e., potential production) and the capacity of the whole landscape to deliver multiple services to the population (i.e., potential supply). In the first part, this methodology is used to report …
