© Institute of Parasitology, Biology Centre ASCR. Between September and November 1991, 12 Owen Stanley skinks, Papuascincus stanleyanus (Booulenger) were collected from various localities on Papua New Guinea and examined for coccidians. Six (50%) were found to harbour four eimerians that we describe here as new. Oocysts of Eimeria burseyi sp. n. were elongate to ellipsoidal with a bilayered wall and measured (length × width, L × W) 36.0 × 24.0 μm, with a L/W ratio of 1.5. Both micropyle and oocyst residuum were absent, but a polar granule was present. Oocysts of Eimeria goldbergi sp. n. were ellipsoidal, with …

Intergenic Transcriptional Interference Is Blocked By Rna Polymerase Iii Transcription Factor Tfiiib In Saccharomyces Cerevisiae, Asawari Korde, Jessica M. Rosselot, David Donze Jan 2014

Intergenic Transcriptional Interference Is Blocked By Rna Polymerase Iii Transcription Factor Tfiiib In Saccharomyces Cerevisiae, Asawari Korde, Jessica M. Rosselot, David Donze

Faculty Publications

The major function of eukaryotic RNA polymerase III is to transcribe transfer RNA, 5S ribosomal RNA, and other small non-protein-coding RNA molecules. Assembly of the RNA polymerase III complex on chromosomal DNA requires the sequential binding of transcription factor complexes TFIIIC and TFIIIB. Recent evidence has suggested that in addition to producing RNA transcripts, chromatin-assembled RNA polymerase III complexes may mediate additional nuclear functions that include chromatin boundary, nucleosome phasing, and general genome organization activities. This study provides evidence of another such "extratranscriptional" activity of assembled RNA polymerase III complexes, which is the ability to block progression of intergenic RNA …

Effects Of Coastal Urbanization On Salt-Marsh Faunal Assemblages In The Northern Gulf Of Mexico, Michael R. Lowe, Mark S. Peterson Jan 2014

Effects Of Coastal Urbanization On Salt-Marsh Faunal Assemblages In The Northern Gulf Of Mexico, Michael R. Lowe, Mark S. Peterson

Faculty Publications

Coastal landscapes in the northern Gulf of Mexico, specifically the Mississippi coast, have undergone rapid urbanization that may impact the suitability of salt-marsh ecosystems for maintaining and regulating estuarine faunal communities. We used a landscape ecology approach to quantify the composition and configuration of salt-marsh habitats and developed surfaces at multiple spatial scales surrounding three small, first-order salt-marsh tidal creeks arrayed along a gradient of urbanization in two river-dominated estuaries. From May 3 to June 4, 2010, nekton and macroinfauna were collected weekly at all six sites. Due to the greater abundance of grass shrimp Palaemonetes spp., brown shrimp Farfantepenaeus …

Linguistic Behavior And Religious Activity, Wendy Baker, David Bowie Jan 2014

Linguistic Behavior And Religious Activity, Wendy Baker, David Bowie

Faculty Publications

Studies have found that Mormons and non-Mormons in Utah exhibit significant linguistic differences. We break this down further by investigating whether there are also differences between Mormons who actively participate in the religion and those who do not, and find significant differences with a medium or larger effect size between the groups for multiple variables. We conclude that when investigating the linguistic correlates of religious affiliation in a community, it is vital to elicit not just respondents’ religious affiliations, but also their level of participation within that religion.

Social Anxiety And Coping Motives For Cannabis Use: The Impact Of Experiential Avoidance, Julia D. Buckner, Michael J. Zvolensky, Samantha G. Farris, Julianna Hogan

Faculty Publications

Social anxiety is robustly associated with cannabis-related problems. This relation appears to be largely explained by coping-oriented motives for cannabis use. Yet, factors associated with coping motives among socially anxious individuals have yet to be identified. The current study tested whether experiential avoidance (i.e., unwillingness to experience distressing internal states) and its subfacets mediated the relation between social anxiety and coping motives for cannabis use. The sample consisted of current (past-month) cannabis-using adults (n = 103). Results indicated that social anxiety was robustly related to experiential avoidance, which was robustly related to coping motives. Follow-up analyses indicated that behavioral avoidance …

In a study of almost 16 000 nest records from seven swallow species across the entire Western Hemisphere, clutch sizes decline with relative laying date in each population, but the slope of this decline grows steeper with increasing distance from the equator. Late-laying birds at all latitudes lay clutches of similar sizes, suggesting that latitudinal differences may be driven primarily by earlier-laying birds. Focused comparisons of site-years in North America with qualitatively different food availability indicate that food supply significantly affects mean clutch size but not the clutch size-lay date regression. Other studies on the seasonality of swallow food also …

Faculty Publications

Habitat fragmentation studies have produced complex results that are challenging to synthesize. Inconsistencies among studies may result from variation in the choice of landscape metrics and response variables, which is often compounded by a lack of key statistical or methodological information. Collating primary datasets on biodiversity responses to fragmentation in a consistent and flexible database permits simple data retrieval for subsequent analyses. We present a relational database that links such field data to taxonomic nomenclature, spatial and temporal plot attributes, and environmental characteristics. Field assessments include measurements of the response(s) (e.g., presence, abundance, ground cover) of one or more species …

Seven Decades Of Development Of The Maize Production System, João Carlos Cardoso Galvão, Glauco Vieira Miranda, Emerson Trogello, Roberto Fritsche-Neto

Faculty Publications

The objective of this work was to compare the maize production system recommended in the decade of 1940 with the system currently employed in Brazil. We used the paper published by Antônio Secundino de São José at Revista Ceres in 1944 to compare the agricultural practices used at that time with the ones currently employed. In the 40's, we found no direct concern with aspects of soil and water conservation. However, the process of raising grain yield based on the use of more on-farm inputs , such as manure and seeds, was initiated at that time. The maize crop was …

An Ethanolic Extract Of Artemisia Dracunculus L. Regulates Gene Expression Of Ubiquitin-Proteasome System Enzymes In Skeletal Muscle: Potential Role In The Treatment Of Sarcopenic Obesity, Heather Kirk-Ballard, Gail Kilroy, Britton C. Day, Zhong Q. Wang, David M. Ribnicky, William T. Cefalu, Z. Elizabeth Floyd

Faculty Publications

Objective: Obesity is linked to insulin resistance, a primary component of metabolic syndrome and type 2 diabetes. The problem of obesity-related insulin resistance is compounded when age-related skeletal muscle loss, called sarcopenia, occurs with obesity. Skeletal muscle loss results from elevated levels of protein degradation and prevention of obesity-related sarcopenic muscle loss will depend on strategies that target pathways involved in protein degradation. An extract from Artemisia dracunculus, termed PMI 5011, improves insulin signaling and increases skeletal muscle myofiber size in a rodent model of obesity-related insulin resistance. The aim of this study was to examine the effect of PMI …

Rice is the most important food security crop in Asia. Information on its seasonal extent forms part of the national accounting of many Asian countries. Synthetic Aperture Radar (SAR) imagery is highly suitable for detecting lowland rice, especially in tropical and subtropical regions, where pervasive cloud cover in the rainy seasons precludes the use of optical imagery. Here, we present a simple, robust, rule-based classification for mapping rice area with regularly acquired, multi-temporal, X-band, HH-polarized SAR imagery and site-specific parameters for classification. The rules for rice detection are based on the well-studied temporal signature of rice from SAR backscatter and …

Faculty Publications

Plants capture solar energy and atmospheric carbon dioxide (CO 2) through photosynthesis, which is the primary component of crop yield, and needs to be increased considerably to meet the growing global demand for food. Environmental stresses, which are increasing with climate change, adversely affect photosynthetic carbon metabolism (PCM) and limit yield of cereals such as rice (Oryza sativa) that feeds half the world. To study the regulation of photosynthesis, we developed a rice gene regulatory network and identified a transcription factor HYR (HIGHER YIELD RICE) associated with PCM, which on expression in rice enhances photosynthesis under multiple environmental conditions, determining …

Estimating Microzooplankton Grazing Half-Saturation Constants From Dilution Experiments With Nonlinear Feeding Kinetics, Bingzhang Chen, Edward A. Laws, Hongbin Liu, Bangqin Huang Jan 2014

Estimating Microzooplankton Grazing Half-Saturation Constants From Dilution Experiments With Nonlinear Feeding Kinetics, Bingzhang Chen, Edward A. Laws, Hongbin Liu, Bangqin Huang

Faculty Publications

To obtain the grazing half-saturation constant (K) of natural microzooplankton assemblages, we used three nonlinear grazing models (rectilinear, Holling type II, and Holling type III) to fit the detailed data (phytoplankton net specific growth rate vs. dilution factor) of individual dilution experiments that show significant concave curves. In the dataset consisting of 528 experiments, 96 experiments show significant concave curves, and the associated chlorophyll a (Chl a) concentrations are significantly higher than those of experiments showing linear or convex curves. Experiments showing concave curves likely reflect that these microzooplankton assemblages were under top-down control. The three models perform equally well …

Reduced Representation Genome Sequencing Suggests Low Diversity On The Sex Chromosomes Of Tonkean Macaque Monkeys, Ben J. Evans, Kai Zeng, Jacob A. Esselstyn, Brian Charlesworth, Don J. Melnick Jan 2014

Reduced Representation Genome Sequencing Suggests Low Diversity On The Sex Chromosomes Of Tonkean Macaque Monkeys, Ben J. Evans, Kai Zeng, Jacob A. Esselstyn, Brian Charlesworth, Don J. Melnick

Faculty Publications

In species with separate sexes, social systems can differ in the relative variances of male versus female reproductive success. Papionin monkeys (macaques, mangabeys, mandrills, drills, baboons, and geladas) exhibit hallmarks of a high variance in male reproductive success, including a female-biased adult sex ratio and prominent sexual dimorphism. To explore the potential genomic consequences of such sex differences, we used a reduced representation genome sequencing approach to quantifying polymorphism at sites on autosomes and sex chromosomes of the tonkean macaque (Macaca tonkeana), a species endemic to the Indonesian island of Sulawesi. The ratio of nucleotide diversity of the X chromosome …

A New Species Of Shrew (Soricomorpha: Crocidura) From West Java, Indonesia, Jacob A. Esselstyn, Anang S. Achmadi, Maharadatunkamsi Jan 2014

A New Species Of Shrew (Soricomorpha: Crocidura) From West Java, Indonesia, Jacob A. Esselstyn, Anang S. Achmadi, Maharadatunkamsi

Faculty Publications

We document the existence of a new species of shrew (Soricomorpha, Soricidae, Crocidura) in West Java, Indonesia, using both morphological and genetic data. Relative to other Southeast Asian Crocidura, the new species is medium-sized with a slender body and long tail, which together readily distinguish it from all other Javan shrews. Morphological differences between the new species and Crocidura paradoxura, another long-tailed shrew that is endemic to Sumatra, are subtle, but genetic differences suggest a long, independent evolutionary history. This description brings to 5 the total number of species of Crocidura recognized from Java. All 5 species are endemic to …

Faculty Publications

We previously reported the presence of environmentally persistent free radicals (EPFRs) in pentachlorophenol (PCP) contaminated soils at a closed wood treatment facility site in Georgia. The reported EPFRs were pentachlorophenoxyl radicals formed on soils under ambient conditions via electron transfer from PCP to electron acceptors in the soil. In this study, we present results for soil and sediment samples from additional Superfund sites in Montana and Washington. Paramagnetic centers associated with different chemical environments were characterized by distinct g-factors and line widths (ΔHp-p). EPFR concentrations in contaminated samples were ∼30×, ∼12×, and ∼2× higher than background samples at the Georgia, …

Presumed Imminence: Judicial Risk Assessment In The Post-9/11 World, Avidan Y. Cover

Faculty Publications

Court opinions in the terrorism context are often distinguished by fact-finding that relates to risk assessment. These risk assessments — inherently policy decisions — are influenced by cultural cognition and by cognitive errors common to probability determinations, particularly those made regarding highly dangerous and emotional events. In a post-9/11 world, in which prevention and intelligence are prioritized over prosecution, courts are more likely to overstate the potential harm, neglect the probability, and presume the imminence of terrorist attacks. As a result, courts are apt to defer to the government and require less evidence in support of measures that curtail civil …

The Influence Of Pornography On Sexual Scripts And Hooking Up Among Emerging Adults In College, Scott Braithwaite, Gwen Coulson, Krista Keddington, Frank D. Fincham

Faculty Publications

The explosive growth in access to the Internet has led to a commensurate increase in the availability, anonymity, andaffordabilityofpornography.Anemergingbodyofresearch has shown associations between pornography and certain behaviors and attitudes; yet, how pornography actually influences these outcomes has not been documented. In two studies (Study 1N=969; Study 2N=992) we examined the hypothesis that pornography influences potentially risky sexual behavior (hooking up) among emerging adults via sexual scripts. Our results demonstrate that more frequent viewing of pornography is associated with a higher incidence of hooking up and a higher number of unique hook up partners. We replicated these effects both cross-sectionally and …
