Fire Ant War Rages At Field Station, Jennifer Southall

University of Mississippi News

OXFORD, Miss. - University of Mississippi entomologist James Anderson likes to quote famed biologist E.O. Wilson on the topic of fire ants. Wilson once said that fire ants are the "Vietnam of entomology." He was referring specifically to the U.S. Department of Agriculture's 20-year, $200 million failed campaign to eradicate the South American invaders through the use of insecticides.

The Biology Of Spaeroma Terebrans In Lake Pontchartrain, Louisiana With Emphasis On Burrowing, Laura Lee Wilkinson

LSU New Orleans Theses and Dissertations

Sphaeroma terebrans (Bate 1866) is an economically and ecologically important cosmopolitan species because this isopod is found burrowed in wood and marine structures of fresh to saline water. Existing literature on S. terebrans focuses on the destruction of red mangrove (Rhizophora mangle) in India, Pakistan, and Florida. This study concentrates on S. terebrans habitat and boring preferences in bald cypress (Taxodium distichum) in Lake Pontchartrain near the Bonnet Carre Spillway, Louisiana. In addition laboratory experiments for water column distribution and substrate preferences were conducted using cypress, Styrofoam, and balsa. Results indicate that this population may be parthenogenic and that wood …

A Cognitive-Behavioral Treatment For Depression In Native American Middle-School Students, Lori B. Listug-Lunde

Theses and Dissertations

Depression and suicide are serious conditions among Native American adolescents. Despite the need for effective treatment approaches in this population, there continues to be a dearth of empirical research in this area. Intervention studies examining Native American adults at risk for depression and Native American youth at risk for suicide have found effectiveness utilizing group skill-based interventions. Group cognitive-behavioral therapy has demonstrated effectiveness among Caucasian adolescents; however, its effectiveness has never been examined with Native American youth experiencing depressive symptoms.

The current study modified, implemented, and evaluated a cognitive-behavioral intervention for depression among Native American middle-school students. A modification of …

The Applicability Of A Habitat Rating System For Low Gradient Streams In Wisconsin To Low Gradient Coldwater Streams In Northern Michigan, Eric Lawrence Forward

Masters Theses

Habitat and fish assemblage data were collected on 12 streams in northern Michigan to assess the applicability of a habitat rating system developed for low gradient streams in Wisconsin in determining stream health in low gradient coldwater streams in northern Michigan. An Index of Biotic Integrity (IBI) developed for coldwater streams in the upper Midwest was used as the measure of stream health. Principal components analysis was used to select a small subset of habitat variables to describe the variation in IBI scores. The seven habitat variables chosen to describe the variation in IBI scores in the final model included: …

Closing The Racial Achievement Gap: The Role Of Reforming Instructional Practices, Harold Wenglinsky

Education Policy Analysis Archives (EPAA)

No Child Left Behind calls for schools to close the achievement gap between races in math and reading. One possible way for schools to do so is to encourage their teachers to engage in practices that disproportionately benefit their minority students. The current study applies the technique of Hierarchical Linear Modeling to a nationally representative sample of 13,000 fourth graders who took the 2000 National Assessment of Educational Progress in mathematics to identify instructional practices that reduce the achievement gap. It finds that, even when taking student background into account, various instructional practices can make a substantial difference.

The New Neurobiology Of Severe Psychiatric Disorders And Its Implications For Laws Governing Involuntary Commitment And Treatment, E Fuller Torrey, Kenneth Kress

ExpressO

Medical advances have led to statutory changes and common law overrulings. This paper argues that such changes are now needed for laws governing the involuntary commitment and treatment of individuals with severe psychiatric disorders. Recent advances in the understanding of the neurobiology of these disorders have rendered obsolete many assumptions underlying past statutes and legal decisions. This is illustrated by using schizophrenia as an example and examining two influential cases: California’s Lanterman-Petris-Short Act (1969) and Wisconsin’s Lessard decision (1972). It is concluded that laws governing involuntary commitment and treatment need to be updated to incorporate the current neurobiological understanding of …

The Yeast Rrna Biosynthesis Factor Ebp2p Is Also Required For Efficient Nuclear Division, Costin N. Ionescu, Sofia Origanti, Michael A. Mcalear

Biological Sciences Faculty Research and Publications

Molecular genetic analysis of the yeast Ebp2 protein has revealed that it is an essential, nucleolar protein that functions in the rRNA biosynthesis pathway. Temperature-sensitive ebp2-1 mutants are defective in the processing of the 27 SA precursor rRNA, and the point substitutions that disrupt this activity cluster towards the central, more highly conserved region of the Ebp2 protein. We report here that other ebp2 mutants exhibit deficiencies associated with defects in chromosome segregation. Yeast cells bearing a 50 amino acid C-terminal truncation allele (ebp2ΔC50) display a slow-growth phenotype and exhibit an increased percentage of cells with …

Kelp Bed Variability And Fish Population Dynamics In Kachemak Bay, Alaska, Judith Ann Hamilton

Marine Biology

Understanding interactions between kelp beds and fishes is essential because anthropogenic changes and natural variability in these beds (composition, density, and distribution) may affect available habitat for fishes. In Alaska, little is known about the annual and seasonal variability of macroalgal cover in kelp beds and corresponding changes in associated fish populations. This study investigated natural variability using monthly SCUBA surveys in Kachemak Bay, Alaska from May 2002 to September 2003. Ten shallow (approximately 7m water depth) nearshore kelp beds with varying degrees of macroalgal cover were surveyed visually for fishes and kelp, and measurements of environmental variables were collected. …

Movement Of The Giant Red Sea Cucumber Parastichopus Californicus In Southeastern Alaska, Kristin Cieciel

Fisheries

This thesis provides information on sea cucumber movement that could inform management of the growing fishery for the sea cucumber, Parastichopus californicus, in Southeast Alaska. Daily movement of individual P. californicus was quantified at six sites to assess spatial variation in movement, at three-month intervals over one year at one site to assess seasonal changes in movement, and densities were measured monthly at three depths over one year. Movements varied among seasons and sites ranging from 0 to 34.5 m·24 h⁻¹, and were highest in summer (mean ± SE = 4.6 ± 0.5 m) and lowest in fall (mean ± …

Perceptions Of Monteverde Youth (14-18 Years Of Age) Towards Pro- And Anti-Tobacco Advertising In Costa Rica, August 2004, Joanne Lee, Sandra Oh, Diana Oliva, Susan Walker, Myriam Scally

Monteverde Institute: Culture, Community, and Health

A study on the youth perceptions of tobacco advertising in the Monteverde region of Costa Rica. Although health risks associated with tobacco use are well documented in the world, tobacco companies continue to seek new smokers to increase sales. As a result, youth have been one of the main targets of tobacco advertising because smokers usually begin smoking in their teen years. This study focused on the youth perceptions of tobacco advertising in the Monteverde region of Costa Rica. Our hypothesis states that while pro-tobacco advertisements attract the attention of youth (between ages 14 and 18 years) to become smokers …

Chemical And Biological Investigation Of The Antarctic Red Alga Delisea Pulchra, Santhisree Nandiraju

USF Tampa Graduate Theses and Dissertations

Our interest in the red alga Delisea pulchra (=D.fimbriata) (Greville) Montagne 1844 (Rhodophyceae, Bonnemaisoniales, Bonnemaisoniaceace) was stimulated by its activity in the biosssays done at Wyeth Pharmaceuticals. Halogenated compounds from D. pulchra interfere with Gram-negative bacterial signaling systems, affect the growth of Gram-positive bacteria, inhibit quorum sensing and swarming motility of marine bacteria (inhibit bacterial communication). They also inhibit surface colonization in marine bacteria and exhibit antifouling properties against barnacle larvae and macroalgal gametes.

Chemical investigation of D.pulchra collected near Palmer Station, Antarctica yielded three new dimeric halogenated furanones, pulchralide A-C (41-43), along with previously reported …

Logic, Language And Legal Science: Are We Lagging Behind?, James S. Mcquade

ExpressO

The central theme of this article is that modern notions of logic, deriving from computer logics and also from the language and logic movement in philosophy, provide a sound basis for legal science and hence for legal writing, law practice and legal education. Scepticism about legal formalism largely derives from the fact that the term logic is still taken to mean the syllogistic logic of Aristotle. Modern notions of logic, generally referred to as formalism or formal studies, view knowledge in general and science in particular in terms of game theory, applying word, number letter and iconic games to data …

Schaefer group of the Center for Computational Quantum Chemistry at the University of Georgia to investigate the structures and characteristics of several hypothetical hydrogen-lithium compounds. The researcher, a physics professor with no background in computational quantum chemistry, and very limited chemistry background, experienced this project much like an upper-level undergraduate science or mathematics major. Approaching the research experience from the perspective of an undergraduate research student, the researcher was able to gain unique insight into the undergraduate …

Differences In Peripheral Noradrenergic Function Among Actively Drinking And Abstinent Alcohol-Dependent Individuals., Ashwin A. Patkar, Charles A. Marsden, Prakash C. Naik, David A. Kendall, Raman Gopalakrishnan, Michael J. Vergare, Stephen P. Weinstein

Department of Psychiatry and Human Behavior Faculty Papers

We examined whether excessive alcohol consumption was related to changes in plasma levels of noradrenaline (NA) and whether these changes recover following abstinence. We also explored whether there were differences in NA levels between Type I and Type II alcoholics and controls during active drinking and abstinence. Plasma concentrations of NA were determined in (1) 27 Caucasian men with alcohol dependence who were regularly drinking (active drinkers) within 24 hours of hospitalization, (2) 29 Caucasian alcohol-dependent men who were in remission (abstinent for a minimum of three months), and (3) 28 race- and gender-matched healthy controls. NA concentrations were significantly …

Terrestrial Movements And Habitat Use Of Gopher Frogs (Rana Capito) At Fort Benning, Georgia, Jonathan H. Neufeldt

Theses and Dissertations

Gopher frogs (Rana capito) were radio-tracked between the 2000 and 2001 breeding seasons to study their terrestrial movements and habitat use in a longleaf pine- sandhill area on the Fort Benning Military Reservation, Georgia. The telemetry research was conducted in response to the need for biological data concerning gopher frog terrestrial habits. Ultimately the data could aid biologists and land managers in describing critical habitat and the development of a management or recovery plan. Twelve gopher frogs were caught at a herpetofaunal array surrounding two neighboring breeding ponds during a post breeding migration, implanted with miniature transmitters, released and radio-tracked …

Adolph Murie: Denali's Wilderness Conscience, Linda S. Franklin

Arctic and Northern Studies

Denali National Park, Alaska substantially owes its stature as Alaska's premier wilderness park to Adolph Murie. Forty years after he retired as park biologist, Murie still influences the perception and management of Denali National Park. Murie's development from childhood to esteemed scientist and wilderness advocate followed a linear progression. His rural upbringing under the tutelage of his older brother, Olaus Murie, cultivated his desire to be a biologist and his appreciation for wild places. His academic training in animal ecology solidified his belief that the management of natural areas must consider all species as essential and equally valuable. His pioneering …

Two Case Histories Of Blast- & Traffic-Induced Vibrations On The Stability Of Burrows Of Endangered Sensitive Ground Dwelling Animals, John A. Barneich, Jay Arabshshi, Steven K. Duke

International Conference on Case Histories in Geotechnical Engineering

Two case histories are presented where jurisdictional authorities expressed a concern regarding the impact of blast and construction traffic induced vibrations on the stability of the burrows of endangered ground dwelling species. The first case history involved the use of explosives proposed to be used for a seismic survey in the vicinity of desert tortoise burrows. The concern was that the use of explosives in the vicinity of a tortoise burrow could cause the collapse of an occupied burrow potentially trapping the tortoise within the burrow. Field tests were performed by constructing artificial tortoise burrows and inducing progressively higher vibration …

Error As Means To Discovery, Kevin C. Elliott

Faculty Publications

This paper argues, first, that recent studies of experimentation, most notably by Deborah Mayo, provide the conceptual resources to describe scientific discovery’s early stages as error-probing processes. Second, it shows that this description yields greater understanding of those early stages, including the challenges that they pose, the research strategies associated with them, and their influence on the rest of the discovery process. Throughout, the paper examines the phenomenon of ‘‘chemical hormesis’’ (i.e., anomalous low-dose effects from toxic chemicals) as a case study that is important not only for the biological sciences but also for contemporary public policy. The resulting analysis …
