Gender (In)Visibility At Abu Ghraib, Marita Gronnvoll

Faculty Research and Creative Activity

This essay explores the gender discourse surrounding the women soldiers implicated in the Abu Ghraib abuse scandal, and the gender silence surrounding their male counterparts. The analysis suggests that the women soldiers in the abuse case, particularly Lynndie England, are held to gendered standards, while the male soldiers are discussed in terms that are nongendered. Further, analysis of the widely disseminated photographs suggests that where the Iraqi male prisoners are excessively gendered and homosexualized, the male soldiers have their presumed heterosexuality preserved. Examination of the Abu Ghraib case suggests implications for rhetorical scholars interested in gender, as well as larger …

Physical Contests For Females In The Japanese Beetle, Popillia Japonica, Paul Switzer, Kipp Kruse

Faculty Research & Creative Activity

We conducted field observations of physical competition for mates, in which a single male attempts to usurp a female from another male, in male Japanese beetles, Popillia japonica Newman (Coleoptera; Scarabaeidae). Physical contests for mates were relatively rare, but when they occurred the challenger male was able to successfully takeover females by dislodging the previously paired resident male in only 18% of contests, suggesting that a substantial prior residency advantage exists in this species. Challenger males that were successful in takeover attempts were significantly larger than the resident male. In contrast, no size pattern was found between intruding males and …

Anaerobic Oxalate Consumption By Microorganisms In Forest Soils, Steven L. Daniel, Christine Pilsl, Harold L. Drake

Faculty Research & Creative Activity

The microbial consumption of oxalate was examined under anaerobic conditions in soil suspensions at 15-20 degree C. With soil (horizon Ah, pH 6.4) from a beech forest, microbial consumption of added oxalate (15 mM) began after 10 days, and oxalate was totally consumed by day 20. The presence of supplemental electron donors (acetate, glucose, vanillate, or hydrogen) or electron acceptors (nitrate or sulfate) did not significantly influence anaerobic oxalate consumption, whereas supplementation of soil suspensions with CO2/bicarbonate totally repressed oxalate consumption. Thus, CO2-, nitrate- or sulfate-respiring bacteria were apparently not active in the anaerobic consumption of oxalate in these soil …

Production Of Methanethiol And Volatile Sulfur Compounds By The Archaeon ‘‘Ferroplasma Acidarmanus’’, David J. Baumler, Kai F. Hung, Kwang Cheol Jeong, Charles W. Kaspar

Faculty Research & Creative Activity

Acidophiles are typically isolated from sulfaterich ecological niches yet the role of sulfur metabolism in their growth and survival is poorly defined. Studies of heterotrophically grown ‘‘Ferroplasma acidarmanus’’ showed that its growth requires a minimum of 100 mM of a sulfate-containing salt. Headspace gas analyses by GC/ MS determined that the volatile sulfur compound emitted by active ‘‘F. acidarmanus’’ cultures is methanethiol. In ‘‘F. acidarmanus’’ cultures grown either heterotrophically or chemolithotrophically, methanethiol was produced constitutively. Radiotracer studies with 35S-labeled methionine, cysteine, and sulfate showed that all three were used in methanethiol production. Additionally, 3H-labeled methionine was incorporated into methanethiol and …

The Cynipoid Genus Paramblynotus: Revision, Phylogeny, And Historical Biogeography (Hymenoptera, Liopteridae), Zhiwei Liu, Fredrik Ronquist, Goeran Nordlander

Faculty Research & Creative Activity

The genus Paramblynotus is the most species-rich genus of the so-called macrocynipoids, the large cynipoid parasitoids of wood-boring and cone-boring insect larvae. The species range in size from some of the largest to the smallest macrocynipoids, comparable in size to microcynipoids. Paramblynotus members occur on all continents except Europe and Australia, with most species being tropical or subtropical. The biology is poorly known but a few observations indicate that the species are parasitoids of beetle larvae. In this monographic revision of the genus, we present a species-level cladistic analysis based on qualitative and quantitative features of the external morphology. For …

Apoptosis Of Dedifferentiated Hepatoma Cells Is Independent Of Nf-Jb Activation In Response To Lps, M. Reidy, Janette Ellis, Erin Schmitz, David Kraus, Gary Bulla

Faculty Research & Creative Activity

Dedifferentiated hepatoma cells, in contrast to most other cell types including hepatoma cells, undergo apoptosis when treated with lipopolysaccharide (LPS) plus the protein synthesis inhibitor cycloheximide (CHx). We recently reported that the dedifferentiated hepatoma cells also exhibit a strong and prolonged NF-jB induction phenotype upon exposure to LPS, suggesting that NF-jB signaling may play a pro-survival role, as reported in several other cell systems. To test the role of NF-jB in preventing LPS-mediated apoptosis, we examined the dedifferentiated cell line M38. Results show that antioxidants strongly inhibited LPS + CHx-mediated cell death in the M38 cells, yet only modestly inhibited …

Native And Exotic Plant Species Exhibit Similar Population Dynamics During Succession, Scott Meiners

Faculty Research & Creative Activity

A growing body of literature has led to the debate in invasion biology whether exotic species perform within communities differently than native taxa due to inherent advantages. To address this issue, the population dynamics of native and exotic plant species were assessed from a 48-year record of permanent plot data from the Hutcheson Memorial Forest Center (New Jersey, USA) to determine rate of increase, lag time, maximum frequency, and the year of peak frequency. Overall, native and exotic species exhibited very similar population dynamics. Rates of increase and length of lag times were similar between native and exotic taxa but …

Life Without Water: Expression Of Plant Lea Genes By An Anhydrobiotic Arthropod, Steven C. Hand, Dana Jones, Michael A. Menze, Trudy L. Witt

Faculty Research & Creative Activity

Anhydrobiotic animals protect cellular architecture and metabolic machinery in the dry state, yet the molecular repertoire supporting this profound dehydration tolerance is not fully understood. For the desiccation-tolerant crustacean, Artemia franciscana, we report differential expression of two distinct mRNAs encoding for proteins that share sequence similarities and structural features with late-embryogenesis abundant (LEA) proteins originally discovered in plants. Bioinformatic analyses support assignment of the LEA proteins from A. franciscana to group 3. This eucoelomate species is the most highly evolved animal for which LEA gene expression has been reported. It is becoming clear that an ensemble of micromolecules and macromolecules …

Alaska At The Crossroads Of Migration: Space-Based Ornithology, Jill L. Deppe, K Wessels, J A. Smith

Faculty Research & Creative Activity

Understanding bird migration on a global scale is one of the most compelling and challenging problems of modern biology. Each year multitudes of migratory birds travel between breeding grounds in Alaska and wintering grounds in the Americas, Asia, and Australia. Here we present the conceptual framework for a spatially explicit, individual-based biophysical migration model driven by dynamic remote sensing observations of atmospheric and land surface conditions to simulate migration routes, timing, energy budgets, and probability of survival. Understanding temporal and spatial patterns of bird migration will provide insight into pressing conservation and human health issues related to this taxonomic group.

Phylogeny And Geological History Of The Cynipoid Wasps (Hymenoptera: Cynipoidea), Zhiwei Liu, Michael S. Engel, David A. Grimaldi

Faculty Research & Creative Activity

The geological history of the wasp superfamily Cynipoidea is reviewed, with the description of various new taxa, being mostly in Late Cretaceous amber from New Jersey and Canada. The various fossil lineages are incorporated into a phylogenetic analysis of the superfamily, and their implications for understanding the evolution of the group are explored. The following new taxa or taxonomic changes are proposed (authorship of all taxa is Liu and Engel): Protimaspidae, new family; Stolamissidae, new family; Stolamissus, new genus; Stolamissus mirabilis, new species; Proliopterinae, new subfamily; Proliopteron, new genus; Proliopteron redactus, new species; Goeraniinae, new subfamily; Goerania, new genus; Goerania …

Over-Expression Of Udp-Glucose Pyrophosphorylase In Hybrid Poplar Affects Carbon Allocation, Heather Coleman, Thomas Canam, Kyu-Young Kang, David Ellis, Shawn Mansfield

Faculty Research & Creative Activity

The effects of the over-expression of the Acetobacter xylinum UDP-glucose pyrophosphorylase (UGPase) under the control of the tandem repeat Cauliflower Mosaic Virus promoter (2335S) on plant metabolism and growth were investigated in hybrid poplar (Populus alba3grandidentata). Transcript levels, enzyme activity, growth parameters, leaf morphology, structural and soluble carbohydrates, and soluble metabolite levels were quantified in both transgenic and wild-type trees. Transgenic 2335S::UGPase poplar showed impaired growth rates, displaying reduced height growth and stem diameter. Morphologically, 2335S::UGPase trees had elongated axial shoots, and leaves that were substantially smaller in size when compared with wild-type trees at equivalent developmental stages. Biochemical analysis …
