Rural Inhabitant Perceptions Of Sandhill Cranes In Wintering Areas Of Northern Mexico, Ingrid Barcelo, Juan Carlos Guzmán-Aranda, Felipe Chávez-Ramírez, Larkin A. Powell

School of Natural Resources: Faculty Publications

Trends in the mid-continent population of sandhill cranes (Grus canadensis) indicate that the species is increasing. A large proportion of this population winters in northern Mexico where possible conflicts between local inhabitants and cranes can occur. We conducted interviews of 40 rural inhabitants living near wetlands used by cranes in three Mexican states. All interviewees had knowledge of cranes and were capable of describing them. The arrival of cranes affected 43% of interviewees. The negative effects were mainly destroyed crops with a subsequent diminished production. Seventy percent of those affected implemented scare tactics to deter the birds, while others (15%) …

Partial Depredations On Northern Bobwhite Nests, Susan Ellis-Felege, Anne Miller, Jonathan S. Burnam, Shane D. Wellendorf, D. Clay Sisson, William E. Palmer, John P. Carroll

School of Natural Resources: Faculty Publications

Partial clutch loss following a predation event is rarely studied in ground-nesting birds despite predation often being the leading cause of nest failure. Partial nest depredation occurs when predators attack but leave some eggs intact. Using continuous video monitoring, we documented a total of 372 initial predation events at nests of Northern Bobwhites (Colinus virginianus). From these, we observed a sample of partial nest pre-dation events (n=47). Partial predation events resulted in three outcomes: (1) The nest failed due to parental abandonment; (2) adult stayed with the nest, but clutch failed to hatch, usually due to further predation events; or …

Patterns Of Incubation Behavior In Northern Bobwhites (Colinus Virginianus), Jonathan S. Burnam, Gretchen Turner, Susan Ellis-Felege, William E. Palmer, D. Clay Sisson, John P. Carroll

School of Natural Resources: Faculty Publications

Patterns of incubation and nesting behavior for many species of birds, especially those with cryptic nests, have been difficult to obtain due to logistical and technological limitations. As a result, little is known about the daily attendance rhythms and behavioral patterns of many species, including the Northern Bobwhite (Colinus virginianus), despite this species being one of the most studied birds in the world. Incubation represents parental investment in offspring, and a multitude of factors may affect investment behaviors, including reproductive ecology, sex and age of parent, habitat quality, clutch age, and timing in the nesting season. Most Northern Bobwhite nests …

Kickin' Sand And Tellin' Lies, Jackson B. Miller, Christopher Forrer

Kickin' Sand and Tellin' Lies: The Play

This document is the script of the two-act play, Kickin’ Sand and Tellin’ Lies, by Jackson B. Miller and Christopher Forrer. The Linfield College Theatre Program presented the world premieres of the play in November 2012 in McMinnville, Oregon and in Pacific City, Oregon. The play was created as part of the Launching through the Surf: The Dory Fleet of Pacific City project, which focuses on the historical and contemporary role of dory fishers and dories in the life of the coastal village of Pacific City, Oregon. Inspired by stories from the project, Kickin’ Sand and Tellin’ Lies is a …

Biological Control Of Solenopsis Fire Ants By Pseudacteon Parasitoids: Theory And Practice, Lloyd W. Morrison

College of Natural and Applied Sciences

Pseudacteon parasitoids are potential biocontrol agents of invasive Solenopsis fire ants. Pseudacteon species that parasitize the invasive S. invicta Buren and S. richteri Forel have been introduced to, and naturally dispersed across, the southeastern USA, although there is no evidence yet that Solenopsis host ant populations have decreased. The ability of introduced Pseudacteon species to regulate Solenopsis populations will depend upon the relative importance of top-down effects in the recipient communities. In this paper, I examine the characteristics of the Pseudacteon/Solenopsis parasitoid/host system and evaluate the extent to which research findings are consistent with top-down control. Laboratory and field experiments …

The Illusory Promise Of Economic Nexus, Adam Thimmesch

Nebraska College of Law: Faculty Publications

The economic nexus standard has gained significant support during the last decade as the proper standard for determining the scope of states' taxing powers under the Dormant Commerce Clause. Unfortunately, however, despite the widespread acceptance of that standard in the abstract, there is no uniform understanding of what economic nexus actually means. State courts that have adopted that standard have generally failed to explain its parameters, and those few courts that have actually addressed the scope of economic nexus have adopted artificially high standards that severely restrict its reach. Actions by state legislatures and revenue authorities have been much the …

Wilderness, Water, And Climate Change, Sandi Zellmer

Nebraska College of Law: Faculty Publications

As the nation searches for climate mitigation and adaptation strategies, the pressure to develop water resources within wilderness areas and to exploit the timber, forage, wildlife, fish, and other virtually untapped components of wilderness will become more acute. This Article makes the case that managers and legislatures should not yield to this pressure and argues that, if anything, the need to preserve untrammeled wilderness characteristics is just as imperative today as it was in 1964 when the Wilderness Act was passed. The Article examines the potency of the Wilderness Act and a trio of federal water law doctrines—federally reserved water …

The South African Constitutional Court And The Unborn, S De Freitas

Law Papers and Journal Articles

The South African Constitutional Court has not yet been confronted with having to make a finding on the status of the unborn against the background of the South African Bill of Rights. Expecting that the Constitutional Court will sometime in the future be approached in this regard, this article presents some preparatory foundational insights on what the approach of the said Court should be. In this regard, the law-making function of the judiciary and the importance of an informative and rational approach towards the protection of the unborn in the judicial process are emphasised. A more nuanced approach by the …

Seven Faces Of Sin: A Study Guide To Biblical Models For How Evil Originates And How It Can Be Overcome, Scott Gambrill Sinclair

Faculty Authored Books and Book Contributions

This book began as a series of classes that I gave to the monks at New Camaldoli Hermitage, Big Sur, California. The monks encouraged me to publish the material. Later when I was teaching a course on the New Testament at the School for Deacons in Berkeley, I remarked that every preacher should preach on "sin" at least twice a year. My students seemed surprised and intrigued and asked me to explain. I attempted to do so briefly, but the explanation was not adequate. Later another member of the faculty heard that I thought that deacons should at least occasionally …

The Number Of X Chromosomes Causes Sex Differences In Adiposity In Mice, Jenny Link, Xuqi Chen, Rebecca Mcclusky, Simon W. Beaven, Peter Tontonoz, Arthur P. Arnold, Karen Reue

Biology

Sexual dimorphism in body weight, fat distribution, and metabolic disease has been attributed largely to differential effects of male and female gonadal hormones. Here, we report that the number of X chromosomes within cells also contributes to these sex differences. We employed a unique mouse model, known as the “four core genotypes,” to distinguish between effects of gonadal sex (testes or ovaries) and sex chromosomes (XX or XY). With this model, we produced gonadal male and female mice carrying XX or XY sex chromosome complements. Mice were gonadectomized to remove the acute effects of gonadal hormones and to uncover effects …

Macroevolutionary Dynamics And Historical Biogeography Of Primate Diversification Inferred From A Species Supermatrix, Christopher A. Emerling, Mark S. Springer, Robert W. Meredith, John Gatesy, Jong Park, Daniel L. Rabosky, Tanja Stadler, Cynthia Steiner, Oliver A. Ryder, Jan E. JanecˇKa, Colleen A. Fisher, William J. Murphy

Biology

Phylogenetic relationships, divergence times, and patterns of biogeographic descent among primate species are both complex and contentious. Here, we generate a robust molecular phylogeny for 70 primate genera and 367 primate species based on a concatenation of 69 nuclear gene segments and ten mitochondrial gene sequences, most of which were extracted from GenBank. Relaxed clock analyses of divergence times with 14 fossil-calibrated nodes suggest that living Primates last shared a common ancestor 71–63 Ma, and that divergences within both Strepsirrhini and Haplorhini are entirely post-Cretaceous. These results are consistent with the hypothesis that the Cretaceous-Paleogene mass extinction of non-avian dinosaurs …

Design, Synthesis, And In Vitro And In Vivo Biological Studies Of A 3′-Deoxythymidine Conjugate That Potentially Kills Cancer Cells Selectively, Qiong Wei, Dejun Zhang, Anna Yao, Liyi Mai, Zhiwei Zhang, Qibing Zhou

Medicinal Chemistry Publications

Thymidine kinases (TKs) have been considered one of the potential targets for anticancer therapeutic because of their elevated expressions in cancer cells. However, nucleobase analogs targeting TKs have shown poor selective cytotoxicity in cancer cells despite effective antiviral activity. 3′-Deoxythymidine phenylquinoxaline conjugate (dT-QX) was designed as a novel nucleobase analog to target TKs in cancer cells and block cell replication via conjugated DNA intercalating quinoxaline moiety. In vitro cell screening showed that dT-QX selectively kills a variety of cancer cells including liver carcinoma, breast adenocarcinoma and brain glioma cells; whereas it had a low cytotoxicity in normal cells such as …

The Removal Of Pluto From The Class Of Planets And Homosexuality From The Class Of Psychiatric Disorders: A Comparison, Peter Zachar, Kenneth S. Kendler

Psychiatry Publications

We compare astronomers' removal of Pluto from the listing of planets and psychiatrists' removal of homosexuality from the listing of mental disorders. Although the political maneuverings that emerged in both controversies are less than scientifically ideal, we argue that competition for "scientific authority" among competing groups is a normal part of scientific progress. In both cases, a complicated relationship between abstract constructs and evidence made the classification problem thorny.

Shared Resistance To Aging And Als In Neuromuscular Junctions Of Specific Muscles, Gregorio Valdez, Juan C. Tapia, Jeff W. Lichtman, Michael A. Fox, Joshua R. Sanes

Anatomy and Neurobiology Publications

Normal aging and neurodegenerative diseases both lead to structural and functional alterations in synapses. Comparison of synapses that are generally similar but respond differently to insults could provide the basis for discovering mechanisms that underlie susceptibility or resistance to damage. Here, we analyzed skeletal neuromuscular junctions (NMJs) in 16 mouse muscles to seek such differences. We find that muscles respond in one of three ways to aging. In some, including most limb and trunk muscles, age-related alterations to NMJs are progressive and extensive during the second postnatal year. NMJs in other muscles, such as extraocular muscles, are strikingly resistant to …

Spxa1 Involved In Hydrogen Peroxide Production, Stress Tolerance And Endocarditis Virulence In Streptococcus Sanguinis, Lei Chen, Xiuchun Ge, Xiaojing Wang, Jenishkumar R. Patel, Ping Xu

Philips Institute for Oral Health Research Publications

Streptococcus sanguinis is one of the most common agents of infective endocarditis. Spx proteins are a group of global regulators that negatively or positively control global transcription initiation. In this study, we characterized the spxA1 gene in S. sanguinis SK36. The spxA1 null mutant displayed opaque colony morphology, reduced hydrogen peroxide (H2O2) production, and reduced antagonistic activity against Streptococcus mutans UA159 relative to the wild type strain. The ΔspxA1 mutant also demonstrated decreased tolerance to high temperature, acidic and oxidative stresses. Further analysis revealed that ΔspxA1 also exhibited a ~5-fold reduction in competitiveness in an animal model of …

Augmenter Of Liver Regeneration (Alr) Promotes Liver Outgrowth During Zebrafish Hepatogenesis, Yan Li, Muhammad Farooq, Donglai Sheng, Chanchal Chandramouli, Tian Lan, Nilesh K. Mahajan, R. Manjunatha Kini, Yunhan Hong, Thomas Lisowsky, Ruowen Ge

Biochemistry and Molecular Biology Publications

Augmenter of Liver Regeneration (ALR) is a sulfhydryl oxidase carrying out fundamental functions facilitating protein disulfide bond formation. In mammals, it also functions as a hepatotrophic growth factor that specifically stimulates hepatocyte proliferation and promotes liver regeneration after liver damage or partial hepatectomy. Whether ALR also plays a role during vertebrate hepatogenesis is unknown. In this work, we investigated the function of alr in liver organogenesis in zebrafish model. We showed that alr is expressed in liver throughout hepatogenesis. Knockdown of alr through morpholino antisense oligonucleotide (MO) leads to suppression of liver outgrowth while overexpression of alr promotes liver growth. …

Analysis Of Embryoid Bodies Derived From Human Induced Pluripotent Stem Cells As A Means To Assess Pluripotency, Steven D. Sheridan, Vasudha Surampudi, Raj R. Rao

Chemical and Life Science Engineering Publications

Human induced pluripotent stem cells (hiPSCs) have core properties of unlimited self-renewal and differentiation potential and have emerged as exciting cell sources for applications in regenerative medicine, drug discovery, understanding of development, and disease etiology. Key among numerous criteria to assess pluripotency includes the in vivo teratoma assay that has been widely proposed as a standard functional assay to demonstrate the pluripotency of hiPSCs. Yet, the lack of reliability across methodologies, lack of definitive clinical significance, and associated expenses bring into question use of the teratoma assay as the “gold standard” for determining pluripotency. We propose use of the in …

Active Hydrophilic Components Of The Medicinal Herb Salvia Miltiorrhiza (Danshen) Potently Inhibit Organic Anion Transporters 1 (Slc22a6) And 3 (Slc22a8), Li Wang, Douglas H. Sweet

Pharmaceutics Publications

Many active components of herbal products are small organic anions, and organic anion transporters were previously demonstrated to be a potential site of drug-drug interactions. In this study, we assessed the inhibitory effects of six hydrophilic components of the herbal medicine Danshen, lithospermic acid, protocatechuic acid, rosmarinic acid, salvianolic acid A, salvianolic acid B, and tanshinol, on the function of the murine organic anion transporters, mOat1 and mOat3. All of Danshen components significantly inhibited mOat1- and mOat3-mediated substrate uptake () with lithospermic acid (LSA), protocatechuic acid, rosmarinic acid (RMA), and salvianolic acid A (SAA) producing virtually complete inhibition under test …
