Retroposon Analysis Of Major Cetacean Lineages: The Monophyly Of Toothed Whales And The Paraphyly Of River Dolphins, Masato Nikaido, Fumio Matsuno, Healy Hamilton, Robert L. Brownell Jr., Yin Cao, Wang Ding, Zhu Zuoyan, Andrew Shedlock, R. Ewan Fordyce, Masami Hasegawa, Norihiro Okada

United States Department of Commerce: Staff Publications

SINE (short interspersed element) insertion analysis elucidates contentious aspects in the phylogeny of toothed whales and dolphins (Odontoceti), especially river dolphins. Here, we characterize 25 informative SINEs inserted into unique genomic loci during evolution of odontocetes to construct a cladogram, and determine a total of 2.8 kb per taxon of the flanking sequences of these SINE loci to estimate divergence times among lineages. We demonstrate that: (i) Odontocetes are monophyletic; (ii) Ganges River dolphins, beaked whales, and ocean dolphins diverged (in this order) after sperm whales; (iii three other river dolphin taxa, namely the Amazon, …

First Finding Of The Amphipod Echinogammarus Ischnus And The Mussel Dreissena Bugensis In Lake Michigan, Thomas F. Nalepa, Don W. Schloesser, Steve A. Pothoven, Darryl W. Hondorp, David L. Fanslow, Marc L. Tuchman, Guy W. Fleischer

United States Department of Commerce: Staff Publications

The first finding of the amphipod Echinogammarus ischnus and the mussel Dreissena bugensis in Lake Michigan is documented. These two species are widespread and abundant in the lower lakes, but had not yet been reported from Lake Michigan. E. ischnus is generally considered a warmwater form that is typically associated with hard substrates and Dreissena clusters in the nearshore zone. Along the eastern shoreline of Lake Michigan, this species was present at rocky, breakwall habitats along the entire north-south axis of the lake. Although not abundant, this species was also found at soft-bottomed sites as deep as 94 m in …

Zebra Mussel (Dreissena Polymorpha) Selective Filtration Promoted Toxic Microcystis Blooms In Saginaw Bay (Lake Huron) And Lake Erie, Henry A. Vanderploeg, James R. Liebig, Wayne W. Carmichael, Megan A. Agy, Thomas H. Johengen, Gary L. Fahnenstiel, Thomas F. Nalepa

United States Department of Commerce: Staff Publications

Microcystis aeruginosa, a planktonic colonial cyanobacterium, was not abundant in the 2-year period before zebra mussel (Dreissena polymorpha) establishment in Saginaw Bay (Lake Huron) but became abundant in three of five summers subsequent of mussel establishment. Using novel methods, we determined clearance, capture, and assimilation rates for zebra mussels feeding on natural and laboratory M. aeruginosa strains offered alone or in combination with other algae. Results were consistent with the hypothesis that zebra mussels promoted blooms of toxic M. aeruginosa in Saginaw Bay, western Lake Erie, and other lakes through selective rejection in pseudofeces. Mussels exhibited high …

The Spatial Variability Of Energy And Carbon Dioxide Fluxes At The Floor Of A Deciduous Forest, Kell Wilson, Tilden Meyers

United States Department of Commerce: Staff Publications

Fluxes of carbon dioxide, water and sensible heat were measured using three different eddy covariance systems above the forest floor of a closed deciduous forest (leaf area index ≈ 6). The primary objective was to examine the representativeness of a single eddy covariance system in estimating soil respiration for time scales ranging from one-half hour to more than one week. Experiments were conducted in which the eddy covariance sensors were in one of three configurations: i) collocated, ii) separated horizontally or iii) separated vertically. A measure of the variation between the three systems (CV’, related to the coefficient …

Tsc13p Is Required For Fatty Acid Elongation And Localizes To A Novel Structure At The Nuclear-Vacuolar Interface In Saccharomyces Cerevisiae, Sepp D. Kohlwein, Sandra Eder, Chan-Seok Oh, Charles E. Martin, Ken Gable, Dagmar Bacikova, Teresa Dunn

Uniformed Services University of the Health Sciences

The TSC13/YDL015c gene was identified in a screen for suppressors of the calcium sensitivity of csg2Δ mutants that are defective in sphingolipid synthesis. The fatty acid moiety of sphingolipids in Saccharomyces cerevisiae is a very long chain fatty acid (VLCFA) that is synthesized by a microsomal enzyme system that lengthens the palmitate produced by cytosolic fatty acid synthase by two carbon units in each cycle of elongation. The TSC13 gene encodes a protein required for elongation, possibly the enoyl reductase that catalyzes the last step in each cycle of elongation. The tsc13 mutant accumulates high levels of long-chain bases …

Citizen Knowledge And Perception Of Black-Tailed Prairie Dog Management, Natalie R. Sexton, Ayeisha Brinson, Phadrea D. Ponds, Kurt Cline, Berton L. Lamb

United States Geological Survey: Publications

What do citizens know about black-tailed prairie dogs, and where do they get their information? When management decisions need to be made regarding an animal such as the black-tailed prairie dog, an understanding of the species and its relationship to humans is necessary. This includes knowing the biology of the animal, where it lives, and how it interacts with other animals. But it is equally important for those making decisions about the species to understand citizens’ knowledge and perceptions so managers can effectively communicate with the public and help the public participate in planning and decision making activities. Unfortunately, what …

Occurrence And Potential Adverse Effects Of Semivolatile Organic Compounds In Streambed Sediment, United States, 1992–1995, Thomas J. Lopes, Edward T. Furlong

United States Geological Survey: Staff Publications

The occurrence and potential adverse effects of select semivolatile organic compounds (SVOCs) in streambed sediment were assessed at 536 sites in 20 major river basins across the United States from 1992 to 1995. Fifty-six SVOCs were detected at one or more sites, and one or more SVOCs were detected at 71% of sites. The northeastern and Great Lakes regions and large metropolitan areas have the highest SVOC concentrations. Polycyclic aromatic hydrocarbons (PAHs) were detected most frequently and at the highest concentrations. Concentrations of PAHs and phthalates were about 10 times higher at sites influenced by urban activities than at sites …

Introduction: Fear And Loathing Of Evolutionary Psychology In The Social Sciences, Daniel Leger, Alan Kamil, Jeffrey A. French

Department of Psychology: Faculty Publications

When one looks at the intellectual landscape of the modern university, at the scholarly and scientific interests of its faculty, the panorama is seamless. There are no discontinuities. The interests of physicists transmogrify into those of chemists, those of chemists into those of biologists, and so on. The lines, the divisions, between departments have been created out of administrative, not intellectual, necessity.
For example, consider the divide between chemistry and biology. There is a set of chemical processes that are characteristic of living systems. Is the study of these processes chemistry or biology? This is a meaningless question. To be …

The Spatial Distribution Of Diversity Between Disparate Taxa: Spatial Correspondence Between Mammals And Ants Across South Florida, Usa, Craig R. Allen, L. G. Pearlstine, D.P. Wojcik, W.M. Kitchens

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Gap Analysis takes a proactive landscape-level approach to conserving native species by identifying nodes of high biological diversity. It uses vertebrate species richness as an index of overall biological diversity. However, it remains unknownwhether or not the spatial distribution of vertebrate diversity correspondswith the diversity of other taxa. We tested whether landscape-level diversity patterns corresponded between a vertebrate and an invertebrate taxon, mammals and ants, across the southern half of the Florida peninsula, USA. Composite digital maps with a 30-m spatial resolution were produced for each taxon. Spatial correspondence between the taxa was determined by normalizing and then subtracting the …

Confirmatory Factor Analysis Of The Coping Style Inventory In A College Sample, Christopher Garth Bellah

Doctoral Dissertations

The present study conducted a confirmatory factor analysis of the Coping Style Inventory (CSI). A comprehensive review of the history of stress and coping research was provided, along with a presentation of suggestions for future research that have indicated a need for a melding of both theory-driven and empirically-driven methodology in coping assessment. Pursuant to this need, a pilot study was conducted to explore the factor structure and psychometric properties of the CSI (N = 560). Results of pilot work using a principle components extraction and a parallel analysis criterion for factor retention indicated that six primary factors were …

The Everglades Ecosystem: From Engineering To Litigation To Consensus-Based Restoration, John J. Fumero, Keith W. Rizzardi

St. Thomas Law Review

"The Everglades were dying. The endless acres of saw grass, brown as an enormous shadow where rain and lake water had once flowed, rustled dry." As late as the 1800's, the Everglades consisted of a 60-mile wide shallow river, seldom more than 2 feet deep, flowing from Lake Okeechobee to Florida Bay. That was before the U.S. Army Corps of Engineers erected 1,400 miles of dikes, dams, levees and water control structures in the name of water supply and flood control Now in the year 2000, more than fifty years after Marjory Stoneman Douglas wrote about the demise of the …

Good Science Or Myopia: Will The 1991 Everglades Settlement Lead To An Optimal Restoration Or Will Phosporus Reductions Be Taken Too Far, William H. Green, Gary V. Perko

St. Thomas Law Review

Everglades water quality restoration: What does it mean? How will it be achieved? How much will it cost? Will it promote re-establishment of historical wildlife populations? Despite years of scientific research, these questions remain answered for the control of phosphorus inputs under Florida's landmark Everglades Forever Act. A one-dimensional approach continues to drive Everglades restoration efforts along a narrow path of extreme phosphorus reductions despite mounting scientific evidence that this could harm wildlife and be unduly costly to society However, moderation of that goal may enhance Everglades wildlife habitat by restoring lost ecosystem functionality, and preserving areas where wildlife mercury …

St. Thomas Law Review

Recent advances in the technologies of molecular genetics have generated a plethora of questions about how these technologies should be used and what, if any, constraints should be imposed on their use. Commentators on the use of the new genetic technologies have, on the one hand, emphasized the benefits to be realized from genetics research in terms of human health and welfare. On the other hand, a handful of critics have focused on the possible misuses of the new technologies and have urged surveillance of genetics and geneticists, lest we again fall into the morass of coercive, or forcible, eugenics. …

Genetic Breakthroughs And The Limits Of Medicine: Short Stature, Growth Hormone, And The Idea Of Dysfunction, Peter H. Schwartz

St. Thomas Law Review

This article reviews arguments that have been presented for the use of growth hormone in some children without growth hormone deficiency. Some of these arguments, this article will claim, utilize confused ideas of dysfunction, and this has led to weak arguments that rely on poor data. Clarifying the concept of dysfunction produces clearer arguments that do not depend on such questionable empirical claims. This analysis aims to serve as a case study of how the careful definition and application of ideas can aid in evaluating the proper purview of medicine. The discussion of future genetic breakthroughs and the powers they …

The Nexus Between Intellectual Property Piracy, International Law, The Internet, And Cultural Values, David J. Stephenson Jr.

St. Thomas Law Review

In a way similar to the dramatic transformation of mass into energy at the speed of light, intellectual property piracy disputes have compellingly special characteristics when multicultural values clash over the Internet. The sudden explosion of Internet use outside of Western Europe and North America, especially in Asia, is most apparent in Singapore, which has the highest per capita use of the Internet anywhere in the world. This rapid global expansion of Internet use has been accompanied by related claims of intellectual property piracy that frequently resemble disputes that have recently arisen in United States and European courts. For example, …

The Ayllu: The Basic Social Unit Of The Aymara People, Tomas Alarcon

St. Thomas Law Review

The Aymara People have inhabited this Earth since time immemorial. Their civilization dates back to 1200 B.C., and their culture was based in the ancient city of Tiwanaku, between 400 and 1000 AD. Since its organization, the dwellers of this great city have endured and resisted conquest by the Inca empire, the Spanish, and the modem states surrounding Lake Titicaca. The Aymara now live in the Andes within the borders of Peru, Bolivia, Chile and Argentina.Their territory is an altiplano or plateau, Poopo, in the region surrounding Lake Titicaca at 4,000 meters above sea level. The Aymara ancestors selected this …

Pivot Irrigation of Livestock Manure
The selection of an appropriate land application method for manure can have an impact on several environmental issues. Individual methods should be evaluated based upon impact on:

• Air quality
• Water quality
• Soil conservation and quality
• Pathogen transmission

The following discussion will review these considerations as they relate to application of manure or lagoon effluent through a center pivot system. A generalized comparison of the relative strengths and weaknesses of alternative application methods is attached in Table 1.

What is an Anaerobic Digester?

The first methane digester plant was built at a leper colony in Bombay, India in 1859. A methane digester system, commonly referred to as an AD (anaerobic digester) is a device that promotes the decomposition of manure or “digestion” of the organics in manure to simple organics and gaseous biogas products. Manure is regularly put into the digester after which the microbes break down the manure into biogas and a digested solid. The digested manure is then deposited into a storage structure. The biogas can be used in an engine generator or burned in a …

Total Reduced Sulfur Concentration in Beef Cattle Feedlots

In 1997, the Nebraska Department of Environmental Quality amended its Title 129 Air Quality Regulations to establish a regulatory threshold for Total Reduced Sulfur (TRS) concentrations under ambient conditions. These thresholds are set at “10.0 parts per million (10.0 PPM) maximum 1 minute average concentration or 0.10 parts per million (0.10 PPM) maximum 30-minute rolling average”. Two agricultural regions of Nebraska with significant cattle finishing in open feedlots came under scrutiny for possible rule violations. In one situation, area feedlots were asked to prepare and implement a TRS control plan.

It was called Southwestern Normal School. Its yearbook was The Oracle. The year was 1901. Oklahoma wasn't even a state when Weatherford started up the small teacher's school. There was no campus. Instead, the town borrowed office space from a beer company. Finally, a building was set up on a hill north of town. In a grand ceremony one morning, the students, faculty and staff marched from downtown Weatherford to their new home.

On a chilly, rainy March 8, 2001, Southwestern re-created the scene, ending with a campus-wide picture. The event was a 100 years in the making, just as …

A Role For Actin, Cdc1p, And Myo2p In The Inheritance Of Late Golgi Elements In Saccharomyces Cerevisiae, Olivia W. Rossanese, Catherine A. Reinke, Brooke J. Bevis, Adam T. Hammond, Irina B. Sears, James O'Connor, Benjamin S. Glick

Faculty Publications

In Saccharomyces cerevisiae, Golgi elements are present in the bud very early in the cell cycle. We have analyzed this Golgi inheritance process using fluorescence microscopy and genetics. In rapidly growing cells, late Golgi elements show an actin-dependent concentration at sites of polarized growth. Late Golgi elements are apparently transported into the bud along actin cables and are also retained in the bud by a mechanism that may involve actin. A visual screen for mutants defective in the inheritance of late Golgi elements yielded multiple alleles of CDC1. Mutations in CDC1 severely depolarize the actin cytoskeleton, and these …
