Serologic Evidence Of West Nile Virus Exposure In North American Mesopredators, Kevin T. Bentler, Jeffrey S. Hall, J. Jeffrey Root, Kaci Klenk, Brandon S. Schmit, Bradley F. Blackwell, Paul C. Ramey, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

Sera from 936 mammalian mesopredators (Virginia opossums, gray foxes, striped skunks, hooded skunks, raccoons, a bobcat, and a red fox) were collected during 2003 and 2004 in California, Arizona, Texas, Louisiana, Ohio, and Wyoming and screened for flavivirus-specific antibodies by an epitope-blocking enzyme-linked immunosobent assay (blocking ELISA). Serum samples positive for antibodies against flaviviruses were screened for West Nile virus (WNV)– specific antibodies by blocking ELISA and selectively confirmed with plaque-reduction neutralization tests. High prevalence rates were observed in raccoons (45.6%) and striped skunks (62.9%). The high WNV antibody prevalence noted in mesopredators, their peridomestic tendencies, and their overall pervasiveness …

Bioeconomic Analysis Of Herpetofauna Road-Kills In A Florida State Park, Stephanie A. Shwiff, Henry T. Smith, Richard M. Engeman, Robert M. Barry, Robin J. Rossmanith, Mark Nelson

United States Department of Agriculture Wildlife Services: Staff Publications

Road-kills are a major cause of mortality for a wide variety of herpetofauna, but management decisions on remediation procedures for reducing losses are based in economic realities. Because funding is finite for species conservation, bioeconomic analysis can assist in justifying, evaluating, and maximizing returns on conservation expenditures, especially for low-profile species such as herpetofauna. Here, we present a bioeconomic analysis of road-killed herpetofauna in Jonathan Dickinson State Park, Florida. Road surveys were conducted daily for four years to identify and enumerate the numbers of each reptile and amphibian species killed by vehicles. Conservative individual valuations applied to the losses formed …

Influence Of Land Use And Climate On Wetland Breeding Birds In The Prairie Pothole Region Of Canada, G. M. Forcey, G. M. Linz, W. E. Thogmartin, W. J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Bird populations are influenced by a variety of factors at both small and large scales that range from the presence of suitable nesting habitat, predators, and food supplies to climate conditions and land-use patterns. We evaluated the influences of regional climate and land-use variables on wetland breeding birds in the Canada section of Bird Conservation Region 11 (CA-BCR1 I ) , the Prairie Potholes. We used bird abundance data from the North American Breeding Bird Survey, land-use data from the Prairie Farm Rehabilitation Administration, and weather data from the National Climatic Data and Information Archive to model effects of regional …

Two New Species Of Rhabdias (Nematoda: Rhabdiasidae) From The Marine Toad, Bufo Marinus (L.) (Lissamphibia: Anura: Bufonidae), In Central America, Yuriy Kuzmin, Vasyl V. Tkach, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two new Rhabdias species are described from the lungs of the cane toad Bufo marinus (L.) from Costa Rica and Nicaragua. Rhabdias alabialis n. sp. differs from other known species of the genus by the remarkable morphology of its head end, i.e., the absence of lips or pseudolabia, the slitlike oral opening, and the triangular shape of the buccal capsule in apical view. Rhabdias pseudosphaerocephala n. sp. is identified as a form previously known in Central and South America as Rhabdias sphaerocephala Goodey, 1924, a species initially described from toads in Europe. The new species is differentiated from R. sphaerocephala …

Fragmentation Of Methyl Chloride Studied By Partial Positive And Negative Ion Yield Spectroscopy, D. Ceolin, Maria Novella Piancastelli, Renaud Guillemin, Wayne C. Stolte, S-W Yu, Oliver Hemmers, Dennis W. Lindle

Environmental Studies Faculty Publications

The authors present partial-ion-yield experiments on the methyl chloride molecule excited in the vicinity of the Cl2p and C1s inner shells. A large number of fragments, cations produced by dissociation or recombination processes, as well as anionic species, have been detected. Although the spectra exhibit different intensity distributions depending on the core-excited atom, general observations include strong site-selective fragmentation along the C–Cl bond axis and a strong intensity dependence of transitions involving Rydberg series on fragment size.

Basic Research Needs For Geosciences: Facilitating 21st Century Energy Systems, U.S. Department Of Energy, Office Of Basic Energy Sciences, Donald J. Depaolo, Franklin M. Orr Jr.

Publications (YM)

Executive Summary

Serious challenges must be faced in this century as the world seeks to meet global energy needs and at the same time reduce emissions of greenhouse gases to the atmosphere. Even with a growing energy supply from alternative sources, fossil carbon resources will remain in heavy use and will generate large volumes of carbon dioxide (CO₂). To reduce the atmospheric impact of this fossil energy use, it is necessary to capture and sequester a substantial fraction of the produced CO₂. Subsurface geologic formations offer a potential location for long-term storage of the requisite large …

Are Hawkmoths The Mysterious Pollinators Of The Jamestown Lily?, W. John Hayden

Biology Faculty Publications

“Hawkmoth flowers are easy to predict but difficult to document,” noted botanist Verne Grant in his comprehensive review of hawkmoth pollination systems in North America (Botanical Gazette 144: 439-449. 1983). Grant included Jamestown (atamasco) lilies (among other zephyr lily species) as examples of plants that are probably hawkmoth- pollinated, but for which the actual pollination mechanism remains undocumented.

The Structure And Function Of Small Nucleolar Ribonucleoproteins, Steve Reichow, Tomoko Hamma, Adrian R. Ferré-D’Amaré, Gabriele Varani

Chemistry Faculty Publications and Presentations

Eukaryotes and archaea use two sets of specialized ribonucleoproteins (RNPs) to carry out sequencespecific methylation and pseudouridylation of RNA, the two most abundant types of modifications of cellular RNAs. In eukaryotes, these protein–RNA complexes localize to the nucleolus and are called small nucleolar RNPs (snoRNPs), while in archaea they are known as small RNPs (sRNP). The C/D class of sno(s)RNPs carries out ribose- 20-O-methylation, while the H/ACA class is responsible for pseudouridylation of their RNA targets. Here, we review the recent advances in the structure, assembly and function of the conserved C/D and H/ACA sno(s)RNPs. Structures of each of the …

Maintenance Of Visual Stability In The Human Posterior Parietal Cortex, Erik Chang, Tony Ro

Publications and Research

Visual stability refers to our stable visuospatial perceptions despite the unstable visual input caused by saccades. Functional neuroimaging results, studies on patients with posterior parietal cortex (PPC) lesions, and single-unit recordings in the lateral intraparietal sulcus of primates indirectly suggest that the PPC might be a potential locus of visual stability through its involvement with spatial remapping. Here we directly explored the role of the PPC in visual stability by applying transcranial magnetic stimulation (TMS) while participants performed a perisaccadic displacement detection task. We show that TMS over the PPC but not a frontal control site alters sensitivity to displacement …

Deconstruction Of Marriage: The Swedish Case, Allan Carlson

San Diego Law Review

The real debate is over the nature of marriage, and of society. The first model noted in this Article emphasizes variability and change. The second model sees marriage as an institution, universal in its basics. For consistent ideological reasons, Sweden's socialists openly embraced the first model, because conventional marriage stood in the way of their collectivist ambitions. Marriage embodied a rival set of loyalties that prevented emergence of the desired androgynous individual dependent on the central state and forestalled the socialization of private life. Until recently, American debate over the meaning of marriage has been much more muddle than the …

Rad51c Deficiency In Mice Results In Early Prophase I Arrest In Males And Sister Chromatid Separation At Metaphase Ii In Females, Sergey Kuznetsov, Manuela Pellegrini, Kristy Shuda, Oscar Fernandez-Capetillo, Yilun Liu, Betty K. Martin, Sandra Burkett, Eileen Southon, Debananda Pati, Lino Tessarollo, Stephen D. West, Peter J. Donovan, Andre Nussenzweig, Shyam K. Sharan

Department of Biochemistry and Molecular Biology Faculty Papers

RAD51C is a member of the RecA/RAD51 protein family, which is known to play an important role in DNA repair by homologous recombination. In mice, it is essential for viability. Therefore, we have generated a hypomorphic allele of Rad51c in addition to a null allele. A subset of mice expressing the hypomorphic allele is infertile. This infertility is caused by sexually dimorphic defects in meiotic recombination, revealing its two distinct functions. Spermatocytes undergo a developmental arrest during the early stages of meiotic prophase I, providing evidence for the role of RAD51C in early stages of RAD51-mediated recombination. In contrast, oocytes …

The Interplay Of Processing Efficiency And Working Memory With The Development Of Metacognitive Performance In Mathematics, Areti Panaoura

The Mathematics Enthusiast

The present study outlines a specific three level hierarchy of the cognitive system and especially the relations of specific cognitive and metacognitive processes in mathematics. The emphasis is on the impact of the development of processing efficiency and working memory ability on the development of metacognitive abilities and mathematical performance. We had used instruments measuring pupils´ metacognitive ability, mathematical performance, working memory and processing efficiency. We administered them to 126 pupils (8-11 years old) three times, with breaks of 3-4 months between them. Results indicated that the development of each of the abilities was affected by the state of the …

Collaborating With Wheat Producers In Demonstrating Areawide Integrated Pest Management, Sean P. Keenan, Kristopher L. Giles, Paul A. Burgener, David A. Christian

Journal of Extension

Focus groups were used to initiate collaborative relationships with wheat producers while learning about their farming history and decision-making. Focus group transcripts illustrate that producers were less confident in evaluating insect management problems compared to weed management. Producers do rely on Cooperative Extension in managing insect problems. Extension educators continue to play an important role in increasing producer's knowledge of simplified field scouting and insect identification technology.

The tomato red spider mite, Tetranychus evansi, is reported as a severe pest of tomato and other solanaceous crops from Africa, from Atlantic and Mediterranean Islands, and more recently from the south of Europe (Portugal, Spain and France). A population of the predaceous mite Phytoseiulus longipes has been recently found in Brazil in association with T. evansi. The objective of this paper was to assess the development and reproduction abilities of this strain on T. evansi under laboratory conditions at four temperatures: 15, 20, 25 and 30°C. The duration of the immature phase ranged from 3.1 to 15.4 days, at …

Vision-Based Ability Of An Ant-Mimicking Jumping Spider To Discriminate Between Models, Conspecific Individuals And Prey, X. J. Nelson, R. R. Jackson

All Peer-Reviewed Publications

Myrmarachne assimilis, an ant-like (myrmecomorphic) jumping spider (Araneae, Salticidae) from the Philippines, is a Batesian mimic of Oecophylla smaragdina, the Asian weaver ant. Salticids are well known for their acute eyesight and the elaborate vision-based display behaviour they adopt during encounters with conspecific individuals, but most salticids are not myrmecomorphic. Despite its unusual morphology, M. assimilis adopts display behaviour during intraspecific interactions that is similar to the display behaviour of more typical salticids. The specificity with which M. assimilis deploys display behaviour is investigated and provides insights into this mimic's ability to differentiate, by sight alone, between models, conspecific individuals …

Implicit Action Encoding Influences Personal-Trait Judgments, P Bach, Sp Tipper

School of Psychology

When an observed action (e.g., kicking) is compatible to a to be produced action (e.g., a foot-key response as compared to a finger-key response), then the self-produced action is more fluent, that is, it is more accurate and faster. A series of experiments explore the notion that vision-action compatibility effects can influence personal-trait judgments. It is demonstrated that when an observed individual carries out an action that is compatible with the participants' response, (1) this individual is identified more fluently, and (2) the observed individual's personality is attributed with the properties of the observed action. For example, if it is …

The Enigma Of Struma Ovarii, Lawrence M. Roth, Aleksander Talerman

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Since its first description in the early part of the twentieth century, struma ovarii has elicited considerable interest because of its many unique features; however, at present a number of aspects remain enigmatic. Although the typical presentation is that of a pelvic mass, unusual clinical manifestations such as hyperthyroidism, ascites, and Meigs' syndrome have been recognised. Uncommon macroscopic and especially histological patterns in struma can cause difficulties in diagnosis. Cystic strumas are challenging to diagnose both macroscopically and histologically. Proliferative changes within struma can be misdiagnosed as cancer. In regard to the occurrence of thyroid-type carcinoma in struma ovarii, precise …

Avpv Neurons Containing Estrogen Receptor-Beta In Adult Male Rats Are Influenced By Soy Isoflavones, Edwin D. Lephart, Lihong H. Bu

Faculty Publications

Background Isoflavones, the most abundant phytoestrogens in soy foods, are structurally similar to 17beta-estradiol. It is known that 17beta-estradiol induces apoptosis in anteroventral periventricular nucleus (AVPV) in rat brain. Also, there is evidence that consumption of soy isoflavones reduces the volume of AVPV in male rats. Therefore, in this study, we examined the influence of dietary soy isoflavones on apoptosis in AVPV of 150 day-old male rats fed either a soy isoflavone-free diet (Phyto-free) or a soy isoflavone-rich diet (Phyto-600). Results: The occurrence of apoptosis in AVPV was examined by TUNEL staining. The incidence of apoptosis was about 10 times …

Understanding The Experiences Of Instructors As They Adopt A Course Management System, Charles R. Graham, Gregory L. Waddoups, Richard E. West

Faculty Publications

In this study, we used qualitative methods to help us better understand the experiences of instructors as they are persuaded to adopt a course management system and integrate it into their teaching. We discuss several patterns explaining how instructors implemented Blackboard, a CMS, by experimenting with individual features, facing both technical and integration challenges, and attempting to adapt Blackboard features to match their goals and practices. We also give explanations for why instructors either a) embraced the tool and grew more dependent on it, b) reduced their use of the tool to only some features, or c) discontinued the tool …

Novel Pathway For Induction Of Latent Virus From Resting Cd4+ T Cells In The Simian Immunodeficiency Virus/Macaque Model Of Human Immunodeficiency Virus Type 1 Latency, Anding Shen, Hung Chih Yang, Yan Zhou, Amanda J. Chase

University Faculty Publications and Creative Works

Although combination therapy allows the suppression of human immunodeficiency virus type 1 (HIV-1) viremia to undetectable levels, eradication has not been achieved because the virus persists in cellular reservoirs, particularly the latent reservoir in resting CD4+ T lymphocytes. We previously established a simian immunodeficiency virus (SIV)/macaque model to study latency. We describe here a novel mechanism for the induction of SIV from latently infected resting CD4+ T cells. Several human cell lines including CEMx174 and Epstein-Barr virus-transformed human B-lymphoblastoid cell lines mediated contact-dependent activation of resting macaque T cells and induction of latent SIV. Antibody-blocking assays showed that interactions between …
