Review Of The Tallgrass Prairie Center Guide To Prairie Restoration In The Upper Midwest. By Daryl Smith, Dave Williams, Greg Houseal, And Kirk Henderson., Gerry Steinauer
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Tallgrass prairie restoration in the Upper Midwest is the focus of this guide. Its geographic area of coverage includes the eastern fifth of South Dakota and Nebraska and northeast Kansas, a region some ascribe to the eastern Great Plains. Two types of prairie restoration are dealt with: prairie reconstruction, which the authors define as creating prairie from scratch on sites where prairie plants no longer exist; and prairie remnant restoration, defined as upgrading degraded existing prairies. The book comprises five sections: "Reconstruction Planning," "Implementing Reconstruction," "Prairie Restoration and Management," "Special Cases," and "Native Seed Production." There are 16 chapters, each …

Caffeine Metabolism And Cytochrome P450 Enzyme Mrna Expression Levels Of Genetically Diverse Inbred Mouse Strains, Neal Addicott, Michael Malfatti, Gabriela G. Loots
Caffeine Metabolism And Cytochrome P450 Enzyme Mrna Expression Levels Of Genetically Diverse Inbred Mouse Strains, Neal Addicott, Michael Malfatti, Gabriela G. Loots
STAR Program Research Presentations
Cytochrome P450 (CYP) enzymes activate or eliminate medications and other xenobiotics, and Caffeine has been used as an indicator of activity for some CYPs. The natural genetic variation in the human population for caffeine metabolizing CYPs does not yet have an established animal model for comparison, but the natural variation in inbred mouse strains presents an attractive starting point. The project gave four different strains of mice a 40mg/kg dose of caffeine and sampled blood and liver tissue after 30 minutes. Samples were analyzed using High Performance Liquid Chromatography (HPLC), reverse transcription PCR (rtPCR), and quantitative PCR (qPCR). The DBA/2J …

Effects Of Xs® Energy Drink On Aerobic Exercise Capacity Of Athletes, Kevin M. Sheehan, Lynn K. Hartzler
Effects Of Xs® Energy Drink On Aerobic Exercise Capacity Of Athletes, Kevin M. Sheehan, Lynn K. Hartzler
Biological Sciences Faculty Publications
A small increase in performance is often the difference between winning and losing for athletes, and energy supplements are marketed to give them a competitive edge. One such supplement is XS® Energy Drink which contains B vitamins, caffeine, taurine, and an herbal adaptogen blend. XS® Energy Drink is primarily designed and marketed as an alertness stimulus; however, it is also marketed to athletes as a performance enhancing supplement. The hypothesis of this investigation was that the consumption of XS® Energy Drink before exercise would increase aerobic capacity (an increase in Vo2max) and time to fatigue, and would decrease time for …
The Proteomic Response Of Sea Squirts (Genus Ciona Congeners) To Heat Stress: Evidence For Differential Thermal Sensitivities, Loredana Serafini
The Proteomic Response Of Sea Squirts (Genus Ciona Congeners) To Heat Stress: Evidence For Differential Thermal Sensitivities, Loredana Serafini
Master's Theses
The sea squirts Ciona intestinalis and C. savignyi have disparate distribution patterns, which may result from differences in their thermal tolerance limits. Because C. intestinalis, an almost cosmopolitan species, has a more widespread distribution, it is thought that it is better adapted to endure a wide range of temperatures. In order to compare the heat stress response between these two congeners, we studied global changes in protein expression, using a proteomics approach. To characterize the response to extreme heat stress, animals of both species were exposed to temperatures of 22°C, 25°C, and 28°C for 6 h, and then were …
Mathematical Modeling Of Clostridium Thermocellum’S Metabolic Responses To Environmental Perturbation, Bless Adotey
Mathematical Modeling Of Clostridium Thermocellum’S Metabolic Responses To Environmental Perturbation, Bless Adotey
Theses and Dissertations--Biosystems and Agricultural Engineering
Clostridium thermocellum is a thermophilic anaerobe that is capable of producing ethanol directly from lignocellulosic compounds, however this organism suffers from low ethanol tolerance and low ethanol yields. In vivo mathematical modeling studies based on steady state traditional metabolic flux analysis, metabolic control analysis, transient and steady states’ flux spectrum analysis (FSA) were conducted on C. thermocellum’s central metabolism. The models were developed in Matrix Laboratory software ( MATLAB® (The Language of Technical Computing), R2008b, Version 7.7.0.471)) based on known stoichiometry from C. thermocellum pathway and known physical constraints. Growth on cellobiose from Metabolic flux analysis (MFA) and Metabolic …

Computer Simulation Of A Hollow-Fiber Bioreactor: Heparan Regulated Growth Factors-Receptors Binding And Dissociation Analysis, Changjiang Zhang
University of Kentucky Doctoral Dissertations
This thesis demonstrates the use of numerical simulation in predicting the behavior of proteins in a flow environment.
A novel convection-diffusion-reaction computational model is first introduced to simulate fibroblast growth factor (FGF-2) binding to its receptor (FGFR) on cell surfaces and regulated by heparan sulfate proteoglycan (HSPG) under flow in a bioreactor. The model includes three parts: (1) the flow of medium using incompressible Navier-Stokes equations; (2) the mass transport of FGF-2 using convection-diffusion equations; and (3) the cell surface binding using chemical kinetics. The model consists of a set of coupled nonlinear partial differential equations (PDEs) for flow and …
Revegetating Burned Arid Lands: Identifying Successful Native Species Using Trait And Competition Analysis: Final Report, Scott R. Abella
Revegetating Burned Arid Lands: Identifying Successful Native Species Using Trait And Competition Analysis: Final Report, Scott R. Abella
Fire Science
Species selection can make the difference between successful revegetation projects and costly failures. Candidate native species for revegetating burned arid lands in the southwestern United States must meet at least two criteria. These species must: (1) be competitive in postfire environments typically dominated by exotic grasses, and (2) be able to become established reliably by seeding or planting. In response to Manager’s Request Task 3 (reestablishment of native vegetation after fires on arid lands) in the 2006 JFS announcement for proposals, this research tackled the problem of selecting native species with the greatest chance of revegetation success by conducting synergistic …

Cropland Nesting By Long-Billed Curlews In Southern Alberta, James H. Devries, Steven O. Rimer, Elizabeth M. Walsh
The Prairie Naturalist
Long-billed curlews (Numenius americanus) are described primarily as a grassland nesting species. However, no studies to date have quantified nest habitat selection among available habitats. During a study of waterfowl nest habitat selection and success in landscapes ranging from cropland to grassland-dominated, we found 9 curlew nests of which 8 were located in active cropland within cropland-dominated landscapes. Cropland nests occurred in fall-seeded winter wheat and spring-seeded barley and nests were clumped in distribution. Four cropland nests and 1 nest in native grass pasture hatched young. Further research is needed to characterize nesting habitat selection and reproductive success …

Preparation of scientific manuscripts and use and presentation of statistics have been topics of several commentaries from previous journal Editors-in-Chief, and have been submitted as invited papers, so I would like to share my perspective as the current Editor-in-Chief (Editor) of The Prairie Naturalist (Journal). Because there is not complete consensus among the experts about when hypothesis testing versus information theoretic methods, or Bayesian versus frequentist methods are suitable, previous Editors have avoided presenting their perspectives (Thompson 2010). I also will avoid presenting my perspective as Editor. I will, however, present my perspective on several of these approaches and then …

Population And Diet Assessment Of White Bass In Lake Sharpe, South Dakota, Andrew E. Ahrens, Travis W. Schaeffer, Melissa R. Wuellner, David W. Willis
The Prairie Naturalist
White bass (Morone chrysops) have been introduced into all 4 South Dakota Missouri River reservoirs and compose a substantial proportion of the annual recreational harvest. To date, limited studies have examined white bass population dynamics and food habits in South Dakota Missouri River reservoirs. Our objective was to examine population dynamics and food habits of white bass in Lake Sharpe, a South Dakota mainstem Missouri River reservoir. White bass consistently consumed invertebrates during May but switched to a more piscivorous diet later in the growing season; most of the fish consumed were gizzard shad (Dorosoma cepedianum). …

The Prairie Naturalist
Knowledge of spawning areas can benefit fisheries management (Marsden et al. 1991). Identification of spawning areas allows managers to protect, enhance, and/or restore critical habitat (Gunn et al. 1996, Thompson 2009), examine important biotic and abiotic conditions necessary for reproduction (Quist et al. 2003), and to efficiently collect broodstock for production (Satterfield and Flickinger 1996). The most effective method to directly identify spawning areas of fish with demersal eggs is to sample the substrate for eggs (Marsden et al. 1991). This method has been used to locate spawning areas of several species (Michaletz 1984, Zorn et al. 1998, Martin 2008). …

Review Of Grouse Of The Plains And Mountains - The South Dakota Story, By Lester D. Flake, John W. Connelly, Thomas R. Kirschenmann, And Andrew J. Lindbloom., Brent E. Jamison
The Prairie Naturalist
Grouse are a fascinating group of birds that offer elaborate breeding displays for birders in the spring, provide sporting opportunities for hunters in the fall, and serve as indicators of grassland health. Though the authors claim that the book targets those who enjoy the outdoors, bird watching, and upland game bird hunting, there is ample reason for ecologists, ornithologists, and grouse researchers to reference this book as well. The book contains general information of interest to a broad audience, but often moves beyond the introductory information to greater detail. Many details are supported by peer-reviewed literature. This book strikes a …
Seasonal Yellow Perch Harvest In Two Dissimilar South Dakota Fisheries, Casey W. Schoenebeck, Michael L. Brown, David O. Lucchesi
Seasonal Yellow Perch Harvest In Two Dissimilar South Dakota Fisheries, Casey W. Schoenebeck, Michael L. Brown, David O. Lucchesi
The Prairie Naturalist
Angler effort and fish harvest in South Dakota have historically been quantified through summer and winter creel surveys. However, the late-summer, pulsed recruitment of yellow perch (Perea flavescens) into a fishery combined with an increase in fall movement and feeding activity suggested September and October could be significant periods of perch harvest in South Dakota lakes. Seasonal trends in angler effort and yellow perch harvest during 2005-2007 were compared for high- and low-quality yellow perch fishery types commonly found in eastern South Dakota glacial lakes. High-quality yellow perch fisheries are characterized by fast growth (mean total length at age-3 greater …

Summer Activity Pattern And Home Range Of Northern Pocket Gophers In An Alfalfa Field, Jon C. Pigage, Helen K. Pigage
The Prairie Naturalist
AIlocation of time for feeding, resting and reproduction in subterranean animals is difficult to determine. Although pocket gophers (Thomomys spp.) are among the most widely studied subterranean rodents, there are conflicting reports on activity measurement in these animals. Activity studies have included opening gopher burrows (Tryon 1947), laboratory studies of activity (Vaughan and Hansen 1961), telemetry studies (Anderson and McMahon 1981, Bandoli 1987, and Cameron et al. 1988), and subcutaneously implanted radioactive gold wires (Gettinger 1984). The diversity of techniques reflects the difficulty of generalizing results from different species of pocket gophers in natural and artificial environments. Patton and …
Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone
Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone
Department of Environmental Studies: Undergraduate Student Theses
The choice of a specific microhabitat represents a compromise among a number of different factors organisms use to monitor habitat suitability. Grassland vegetation structure can vary widely along environmental gradients over a relatively small area. This vegetation structure can have a large influence on habitat selection by grasshoppers (Orthoptera). However, it is not clear which vegetation characteristics are most important in determining grasshopper abundance. We found that plant biomass, plant species richness, and plant quality all have an effect on grasshopper abundance and distribution. We observe that these affects vary both within and among the two years of data collection. …

Resource Selection Of Greater Prairie-Chicken And Sharp-Tailed Grouse Broods In Central South Dakota, Mark A. Norton, Kent C. Jensen, Anthony P. Leif, Thomas R. Kirschenmann, Gregaory A. Wolbrink
The Prairie Naturalist
Habitat use of sympatric greater prairie-chicken (Tympanuchus cupido) and sharp-tailed grouse (T. phasianellus) broods during the brood-rearing season has not been quantified for stable prairie grouse populations in large contiguous grassland landscapes in the Northern Great Plains. Characteristics of habitats used by prairie grouse broods were described based on data collected from 35 broods (18 greater prairie-chicken and 17 sharp-tailed grottse) during the breeding seasons of 2004 and 2005. Greater prairie-chicken and sharp-tailed grouse broods used vegetation with visual obstruction heights 2:26 cm and 37 cm, respectively. Greater prairie-chicken broods selected western wheatgrass (Pascopyrum smithii …

Current Distribution Of Rare Fishes In Eastern Wyoming Prairie Streams, Christina E. Barrineau, Elizabeth A. Bear, Anna C. Senecal
The Prairie Naturalist
Distributions of native fishes have declined throughout the Great Plains region. Over 50% of native fishes within the Missouri River drainage in Wyoming have experienced declines in distributions. Thus, the primary goal of our study was to assess current distribution of rare native fishes in eastern Wyoming prairie streams. Of the 10 rare fishes sampled, goldeye (Hiodon alosoides), western silvery minnow (Hybognathus argyritis), plains minnow (H. hankinsoni), and Iowa darter (Etheostoma exile) have experienced declines in distribution over the last decade. Plains topminnow (Fundulus sciadicus) appears to be expanding to areas outside …
Examination Of Owl Pellets For Northern Pocket Gophers At Crescent Lake National Wildlife Refuge, Nebraska, Stacey L. Bonner, Keith Geluso
Examination Of Owl Pellets For Northern Pocket Gophers At Crescent Lake National Wildlife Refuge, Nebraska, Stacey L. Bonner, Keith Geluso
The Prairie Naturalist
Analysis of regurgitated pellets from owls is a well-known and nondestructive method that provides useful information regarding diet (Errington 1930). This technique also is used to examine composition of small mammal communities and distribution of prey species (e.g. Kamler et al. 2003, Torre et al. 2004, Poole and Matlack 2007). In western Nebraska, two species of owls that regularly breed in the region are the common barn owl (Tyto alba) and great horned owl (Bubo virginianus). In the early 1970s, Rickart (1972) studied the diet of both species at Crescent Lake National Wildlife Refuge (CLNWR), Garden …

The Prairie Naturalist
The central stoneroller (Campostoma anomalum) is a herbivore that can have substantial effects on algal communities, nutrient dynamics, and energy flow in streams. Despite its importance in lotic ecosystems, little is known about its population dynamics in streams of the Great Plains. Our objective was to describe age structure, age-specific mortality, and growth rates of central stonerollers in three Iowa streams. We sampled fish from 41 reaches during June-August 2007. We sampled 466 central stonerollers, of which we aged 192. Fish varied in length from 32 to 130 mm and in age from age 0 to 4 years. …

Diets Of Nesting Swainson's Hawks In Relation To Land Cover In Northwestern North Dakota, Robert K. Murphy
Diets Of Nesting Swainson's Hawks In Relation To Land Cover In Northwestern North Dakota, Robert K. Murphy
The Prairie Naturalist
Relationships between land use practices and types of prey used by Swainson's hawks (Buteo swainsoni) in the Northern Great Plains is of increasing interest as the quantity and quality of habitat in the region declines. I recorded 1,284 prey items at 18 Swainson' s hawk nesting areas throughout northwestern North Dakota during summer 1986-1987. After correcting for detectability biases and food needs of adults, I estimated (90% CI) 2,087-2,859 total prey individuals and 138.3-206.7 kg of prey biomass (x = 69.8 g/item) were consumed by adult and nestling Swainson's hawks during my study. Major prey (>10% overall …

Background
Human scabies is a debilitating skin disease caused by the “itch mite” Sarcoptes scabiei. Ordinary scabies is commonly treated with topical creams such as permethrin, while crusted scabies is treated with topical creams in combination with oral ivermectin. Recent reports of acaricide tolerance in scabies endemic communities in Northern Australia have prompted efforts to better understand resistance mechanisms and to identify potential new acaricides. In this study, we screened three essential oils and four pure compounds based on eugenol for acaricidal properties.
Methodology/Principal Findings
Contact bioassays were performed using live permethrin-sensitive S. scabiei var suis mites harvested from …Understanding Acquired Resistance To Lapatinib In Breast Cancer Cells, Jen-Te Tseng
Understanding Acquired Resistance To Lapatinib In Breast Cancer Cells, Jen-Te Tseng
Dissertations and Theses (Open Access)
Signaling through epidermal growth factor receptor (EGFR/ErbB) family members plays a very important role in regulating proliferation, development, and malignant transformation of mammary epithelial cells. ErbB family members are often over-expressed in human breast carcinomas. Lapatinib is an ErbB1 and ErbB2 tyrosine kinase inhibitor that has been shown to have anti-proliferative effects in breast and lung cancer cells. Cells treated with Lapatinib undergo G1 phase arrest, followed by apoptosis. Lapatinib has been approved for clinical use, though patients have developed resistance to the drug, as seen previously with other EGFR inhibitors. Moreover, the therapeutic efficacy varies significantly within the patient …
