Effect Of Fuel Deposition Rate On Departure Fuel Load Of Migratory Songbirds During Spring Stopover Along The Northern Coast Of The Gulf Of Mexico, Kristen M. Covino

Biology Faculty Works

Migrants are generally assumed to minimize their overall migration time by adjusting their departure fuel loads (DFL) in relation to anticipated and experienced fuel deposition rates (FDRs). We utilized a 21-yr long migration banding station dataset to examine the relationship between FDR and DFL during spring migration in six Nearctic-Neotropical migratory songbird species during stopover along the northern coast of the Gulf of Mexico (GOM) following trans-gulf flight. Estimates of fuel stores, stopover durations, and FDRs from our long term migration data set were combined to determine DFL. We expected and found that migrants across all six species adjust their …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION: One of the limitations of liquid inoculation with rhizobia in the planting furrow in the dry bean crop is the small number of research studies involving this type of inoculation and the establishment of application rates suitable for good performance of biological nitrogen fixation (BNF). Thus, the aims of this study were to evaluate the viability of liquid inoculation in the planting furrow in dry bean BRS Estilo and certify if the increase in the inoculation rate benefits its symbiosis with Rhizobium sp.

MATERIALS AND METHODS: A field experiment was carried out in a no-till planting system in …

The History And Current Status Of Glyphosate, Stephen O. Duke

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Glyphosate is the only herbicide to target the enzyme 5-enolpyruvyl-3-shikimate phosphate synthase (EPSPS). It is a high use rate, non-selective herbicide that translocates primarily to metabolic sinks, killing meristematic tissues away from the application site. Its phloem-mobile properties and slow action in killing weeds allow the herbicide to move throughout the plant to kill all meristems, making it effective for perennial weed control. Since commercialization in 1974, its use has grown to dominate the herbicide market. Much of its use is on transgenic, glyphosate-resistant crops (GRCs), which have been the dominant transgenic crops worldwide. GRCs with glyphosate provided the most …

Comprehensive Dual Liquid Chromatography With Quadruple Mass Spectrometry (Lc1ms2 × Lc1ms2 = Lc2ms4) For Analysis Of Parinari Curatellifolia And Other Seed Oil Triacylglycerols, William C. Byrdwell

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Online two-dimensional (2D) comprehensive liquid chromatography (LC × LC) has become increasingly popular. Most LC × LC separations employ one or more detectors at the outlet of the second dimension, ²D, with very short runs to avoid undersampling. We used six detectors, including dual parallel mass spectrometry (LC1MS2), for detection of the first dimension, ¹D. We made an argentation (silver-ion) UHPLC column from a strong cation exchange column for ²D, coupled with UV and LC1MS2 detection. LC1MS2 in ¹D combined with LC1MS2 in ²D, plus five other detectors, constituted LC2MS4 in a comprehensive LC1MS2 × …

Facile Purification Of Milligram To Gram Quantities Of Condensed Tannins According To Mean Degree Of Polymerization And Flavan-3-Ol Subunit Composition, Ron H. Brown, Irene Murray-Harvey, Wayne E. Zeller, Laurie Reinhardt, Elisabetta Stringano, An Gea, Christopher Drake, Honorata M. Ropiak, Christos Fryganas, Aina Ramsay, Emily E. Hardcastle

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Unambiguous investigation of condensed tannin (CT) structure−activity relationships in biological systems requires well-characterized, high-purity CTs. Sephadex LH-20 and Toyopearl HW-50F resins were compared for separating CTs from acetone/water extracts, and column fractions analyzed for flavan-3-ol subunits, mean degree of polymerization (mDP), and purity. Toyopearl HW-50F generated fractions with higher mDP values and better separation of procyanidins (PC) and prodelphinidins (PD) but required a prepurification step, needed more time for large scale purifications, and gave poorer recoveries. Therefore, two gradient elution schemes were developed for CT purification on Sephadex LH-20 providing 146−2000 mg/fraction. Fractions were analyzed by thiolysis and NMR spectroscopy. …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Highly efficient antimicrobial agents with low toxicity and resistance have been enthusiastically pursued to address public concerns on microbial contamination in food. Silver nanoclusters (AgNCs) are known for their ultrasmall sizes and unique optical and chemical properties. Despite extensive studies of AgNCs for biomedical applications, previous research on their application as antimicrobials for food applications is very limited. Here, for the first time, by incorporating AgNCs (~2 nm in diameter) into zein films that are widely used as food packaging materials, we developed a novel coating material with potent antimicrobial activity, low toxicity to human cells, and low potential to …

Gypenosides Reduced The Risk Of Overweight And Insulin Resistance In C57bl/6j Mice Through Modulating Adipose Thermogenesis And Gut Microbiota, Jie Liu, Yanfang Li, Puyu Yang, Jianchun Wan, Qimeng Chang, Thomas T. Y. Wang, Weiying Lu, Yaqiong Zhang, Qin Wang, Liangli Lucy Yu

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

This study investigated whether and how gypenosides from jiaogulan tea at 100 and 300 mg/kg/day levels could reduce the development of overweight and insulin resistance in C57 BL/6J mice fed a high-fat diet in 12 weeks. The 300 mg/kg/ day gypenosides supplement significantly reduced final body weight, plasma total cholesterol, and homeostasis model assessment-estimated insulin resistance (HOMA-IR) index by 19.9%, 40%, and 36%, respectively, compared with the high-fat diet control group. Gypenosides also increased brown adipocyte tissue activity and white adipose tissue browning. The expression of genes involved in mitochondrial activity and fatty acid β-oxidation were also increased in both …

Novel Functions Of Cardiolipin Remodeling In Saccharomyces Cerevisiae And Mammalian Cells: Implications For Barth Syndrome, Wenjia Lou

Wayne State University Dissertations

Cardiolipin (CL) is a unique phospholipid that is primarily localized within the inner mitochondrial membrane. Newly synthesized CL undergoes acyl remodeling to produce CL species enriched with unsaturated acyl groups. The tafazzin gene (TAZ) encodes a transacylase that remodels CL. Deficiencies in CL remodeling cause Barth syndrome (BTHS), an X-linked genetic disorder resulting from TAZ mutations that lead to reduced total CL content and an accumulation of monolysocardiolipin (MLCL), an intermediate of the CL remodeling pathway. However, which of these biochemical outcomes contributes to the physiological defects is not fully understood.

Deletion of yeast CL phospholipase rescues the taz1growth phenotype. …

Human Kinome In Skeletal Muscle Insulin Resistance, Yue Qi

Wayne State University Dissertations

Protein kinases play fundamental roles in regulation of biological processes and functions, such as insulin signaling and glucose metabolism. Dysregulation of protein kinases may cause impaired cell signaling and human diseases, such as metabolic syndrome and type 2 diabetes (T2D). Skeletal muscle is the main site responsible for insulin-stimulated glucose disposal, and insulin resistance in skeletal muscle is one of the key features of the pathogenesis of T2D. Therefore, malfunction of protein kinases and their interaction proteins may contribute to the molecular mechanism of insulin resistance in human skeletal muscle. However, no large scale profiling study has been reported to …

The Political Determinants Of Food Security: Democracy, Decentralization, And Federalism, Catherine E. Schmitt-Sands

Wayne State University Dissertations

Food security is partially determined by politics. This dissertation examines three political determinants of food security: democracy, decentralization, and federalism. Each one is operationalized and tested quantitatively against food security using a dataset of all countries from 1990 to 2011, although each model employs a different subset of the dataset. Democracy is divided along two dimensions: political rights and civil liberties. Both are significant positive predictors of food security. Increases in civil liberties are more consistently and strongly associated with food security than increases in political rights.

Decentralization is assessed along three dimensions: fiscal, administrative, and political. Fiscal and administrative …

Attention Deficit Identity Discourse: Exploring The Ableist Limitations And The Liberative Potential Of The Contested Adhd Self, Nathan T. Stewart

Wayne State University Dissertations

The specific objective of this project is to elaborate general rhetorical resources and strategies that can allow for ADHDers to both cultivate/reclaim a positive sense of self in the face of multiple forms of stigmatizing discourse and begin the process of challenging that discourse. Working from a disability studies perspective, I identify both challenges and opportunities to develop a positive sense of self through the examination of nostalgia in ADHD discourse, polysemic ADHD medical discourse, and the use of counternarratives as a resource to reframe stigmatizing master narratives. This project concludes by emphasizing that those with what I identify as …

Justice... Not Just Us: How One District-Level Social Justice-Oriented Transformative Leadership Team Addresses Marginalization And Oppression, Thomas Arnold Zook

Wayne State University Dissertations

ABSTRACT

Our democracy depends upon an educated populace; thus, educators have an ethical and a moral obligation to provide equitable opportunities for all children to obtain an education “worth wanting” (Howe, 1997). Yet, too often the pleas of countless children yearning to be accepted go unnoticed. In the U.S., millions of students fail to realize similar academic success and social inclusion simply because of their (self or imposed) identification with a non-dominant identity group, and this can only be understood as institutionalized injustice. Often hiding in plain sight, marginalization and oppression take many forms, yet for their victims the results …

The Role Of Pparγ In Placental Development And Disease, Leena Kadam

Wayne State University Dissertations

The placenta in mammals forms the maternal fetal interface serving as the source of nutrition for the fetus throughout gestation. It comprises of two major trophoblast lineages: (i) the decidua invading extra-villous trophoblast (EVT) and (ii) the placenta residing villous trophoblast (VT). The EVT’s invade the maternal endometrium to establish pregnancy and secure blood-flow to the implantation site. The VT villous trophoblast forms the main maternal-fetal exchange surface and ensures nutrient and gas exchange to facilitate growth throughout pregnancy. Additionally, both lineages are involved in immunological functions such as maintaining allogenic tolerance and regulation of immune cell activation at the …

Impact Of Body Condition On Influenza A Virus Infection Dynamics In Mallards Following A Secondary Exposure, Nicholas G. Dannemiller, Colleen T. Webb, Kenneth R. Wilson, Kevin T. Bentler, Nicole L. Mooers, Jeremy W. Ellis, J. Jeffrey Root, Alan B. Franklin, Susan A. Shriner

United States Department of Agriculture Wildlife Services: Staff Publications

Migratory waterfowl are often viewed as vehicles for the global spread of influenza A viruses (IAVs), with mallards (Anas platyrhynchos) implicated as particularly important reservoir hosts. The physical demands and energetic costs of migration have been shown to influence birds' body condition; poorer body condition may suppress immune function and affect the course of IAV infection. Our study evaluated the impact of body condition on immune function and viral shedding dynamics in mallards naturally exposed to an H9 IAV, and then secondarily exposed to an H4N6 IAV. Mallards were divided into three treatment groups of 10 birds per …

The Oil Pollution Act of 1990 establishes liability for injuries to natural resources because of the release or threat of release of oil. Assessment of injury to natural resources resulting from an oil spill and development and implementation of a plan for the restoration, rehabilitation, replacement or acquisition of natural resources to compensate for those injuries is accomplished through the Natural Resource Damage Assessment (NRDA) process. The NRDA process began within a week of the Deepwater Horizon oil spill, which occurred on April 20, 2010. During the spill, more than 8500 dead and impaired birds representing at least 93 avian …

The Deepwater Horizon oil spill released 134 million gallons of crude oil into the Gulf of Mexico making it the largest oil spill in US history and exposing fish, birds, and marine mammals throughout the Gulf of Mexico to its toxicity. Fish eating waterbirds such as the double-crested cormorant (Phalacrocorax auritus) were exposed to the oil both by direct contact with the oil and orally through preening and the ingestion of contaminated fish. This study investigated the effects of orally ingestedMC252 oil-contaminated live fish food by double-crested cormorants on oxidative stress. Total, reduced, and oxidized glutathione levels, superoxide …

Development Of Toxic Bait To Control Invasive Wild Pigs And Reduce Damage, Nathan P. Snow, Justin A. Foster, John C. Kinsey, Simon T. Humphrys, Linton D. Staples, David G. Hewitt, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Populations of invasive wild pigs (Sus scrofa) are increasing in many regions of the world, in particular the United States and Australia. Invasive wild pigs cause extensive damage to ecological resources and agriculture. Development and registration of a safe and humane toxic bait offers a practical and cost effective tool to control invasive species. Currently, no toxicants are approved for use on invasive wild pigs in the United States and those approved in Australia are under scrutiny because of concerns regarding humaneness and effects on nontarget species. We tested a newly formulated bait containing the microencapsulated active ingredient, …

Strategies For Evading Blackbird Damage, George M. Linz, Page E. Klug

United States Department of Agriculture Wildlife Services: Staff Publications

Foraging blackbird flocks have great mobility as they search for food that is plentiful, is easily accessed, and has a high nutritional value. Ripening corn, rice, and sunflower fit those criteria, as does seeded rice. The birds will move from field to field to find the ideal combination of energy spent to discover food versus the energy value of the food (Pyke et al. 1977). An extraordinary effort is often needed to actively move the birds from a foraging location with a high positive value (e.g., close to roost and early ripening sunflower) versus a location with a I~w value …

Scoping studies were designed whereby double-crested cormorants (Phalacocorax auritus) were dosed with artificially weathered Deepwater Horizon (DWH) oil either daily through oil injected feeder fish, or by application of oil directly to feathers every three days. Preening results in oil ingestion, and may be an effective means of orally dosing birds with toxicant to improve our understanding of the full range of physiological effects of oral oil ingestion on birds. Blood samples collected every 5–6 days were analyzed for a number of clinical endpoints including white blood cell (WBC) estimates and differential cell counts. Plasma biochemical evaluations were …

Survival And Habitat Selection Of Canada Geese During Autumn And Winter In Metropolitan Chicago, Usa, Brett E. Dorak, Michael P. Ward, Michael W. Eichholz, Brian E. Washburn, Timothy P. Lyons, Heath M. Hagy

United States Department of Agriculture Wildlife Services: Staff Publications

Winter distribution and resource use of animals is driven by myriad interacting biotic and abiotic factors. Urban areas provide sanctuaries from hunting for game animals and may have thermal benefits during winter through reduced thermoregulatory costs. We deployed cellular GPS transmitters affixed to neck collars of 41 Canada Geese (Branta canadensis) in the Greater Chicago Metropolitan Area (GCMA) of northeastern Illinois, USA, to determine habitat selection and survival during autumn and winter. Canada Geese selected green spaces (59.8%) in greater proportion than available (14%), but they also regularly used industrial urban habitats such as rooftops and rail yards …
