The Role Of Toxicants In Forest Management, Wendy M. Arjo

United States Department of Agriculture Wildlife Services: Staff Publications

Although the emphasis of the Olympia Field Station is on the development of non-lethal methods to control pest species, sometimes lethal methods are necessary. Toxicants can be an effective means of quickly reducing high populations of some problem animals or maintaining acceptable population densities. Depending on their mode of action, toxicants are classified into three categories: fumigants, acute toxicants and chronic toxicants.

Developing Approaches To Reduce Wildlife Damage To Forest Resources, Dale L. Nolte

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife impacts on forest resources can be extensive. Although damage is generally considered in terms of reduced productivity or delayed harvest cycles, attempts to replace trees after a harvest or a fire can fail because of foraging wildlife. Wildlife, particularly mammalian herbivores, can impede attempts to establish native plants to increase forest diversity, improve riparian areas, re-vegetate disturbed sites, restore endangered or threatened plants, or to create or improve habitat for wildlife. Foraging wildlife can be extremely detrimental if animals browse on plants before seedlings are well established, or if foraging is continuous or intense. Native plant projects are often …

Developing Strategies To Alleviate Wildlife Damage To Forest Resources, Dale L. Nolte

United States Department of Agriculture Wildlife Services: Staff Publications

Does the presence of wildlife always pose a problem when reforesting a site? Not necessarily. However, the potential impacts of wildlife need to be considered. The intensity or severity of impacts caused by wildlife will reflect the species and density of animals present, along with existing habitat conditions. Whether these impacts create a problem depends on the objectives of the producer and the resources available to achieve the original goal. Wildlife will not be a problem for projects with unlimited resources and time. The repeated plant and replant methods will ultimately lead to some form of success. However, wildlife can …

Automatic Classification Of African Elephant (Loxodonta Africana) Follicular And Luteal Rumbles, Michael T. Johnson, Patrick J. Clemins

Dr. Dolittle Project: A Framework for Classification and Understanding of Animal Vocalizations

Recent research in African elephant vocalizations has shown that there is evidence for acoustic differences in the rumbles of females based on the phase of their estrous cycle (1). One reason for these differences might be to attract a male for reproductive purposes. Since rumbles have a fundamental frequency near 10Hz, they attenuate slowly and can be heard over a distance of several kilometers. This research exploits differences in the rumbles to create an automatic classification system that can determine whether a female rumble was made during the luteal or follicular phase of the ovulatory cycle. This system could be …

Preemptive Action: When, How, And To What Effect?, M. Elaine Bunn

Strategic Forums

This Strategic Forum paper examines the Bush administration’s evolving concept of preemptive action in the post-9/11 security environment. It analyzes the strategic rationale behind the emphasis on preemption—particularly concerns about rogue states, terrorism, and weapons of mass destruction (WMD)—and distinguishes between preemptive and preventive uses of force. The author explores historical precedents, legal and ethical considerations, operational requirements, and the potential military and political consequences of preemptive action. The paper argues that while preemption remains a legitimate option in extreme circumstances, especially where WMD threats are imminent, its application requires careful evaluation of intelligence reliability, proportionality, alliance cohesion, and long-term …

Fixations/Solutions, Matthew Wolf-Meyer

Reconstruction: Studies in Contemporary Culture

[First paragraph]

When the idea of this issue’s theme came to me, I was standing in a crowd of my peers, members of my generation, listening to Godspeed You! Black Emperor. As with all concerts, the performers left the stage to signal their eventual encore, and when they returned, they returned with the announcement that the U.S. military had begun its bombing, and formal invasion, of Iraq. Whether the idea for the issue had come to me prior to this moment, or as a result of it, I am unsure; I had, however, earlier decided that the summer issue we …

Mountain Beaver: The Little Rodent With A Large Appetite, Wendy M. Arjo

United States Department of Agriculture Wildlife Services: Staff Publications

While walking through open forest areas you might have found yourself falling into large holes that dot the landscape. After extracting your foot from the hole you may have noticed other holes nearby, some with clipped sword fern or forbs neatly arrayed around the hole. These symmetrical burrows are home to the mountain beaver. The mountain beaver, considered the most primitive living rodent species, descended from a now extinct family of rodents over 30 million years ago. Seven subspecies of mountain beaver are recognized with one subspecies in coastal California currently listed as an endangered species. This semi-fossorial rodent, endemic …

Fencing Out Big Game Species, Dale L. Nolte

United States Department of Agriculture Wildlife Services: Staff Publications

Fencing is the most effective approach to deter big-game movements. However, cost to install and maintain effective fences can be prohibitive. Further, fences across rough terrain can be impractical. Although simple designs can effectively deter deer and elk from some sites, more complex designs are necessary if the protected resource is highly desirable or if normal transitory patterns, such as migratory routes or paths to water, are disrupted. The task becomes more daunting if your desire is to construct an impregnable fence.

Predators On Red-Winged Blackbird Nests In Eastern North Dakota, Richard S. Sawin, Mark W. Lutman, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Predation has consistently been identified as the most common cause of nest failure for Red-winged Blackbirds (Agelaius phoeniceus). During May and June, 2000 and 2001, we used infrared-triggered camera systems to identify potential nest predators on artificially relocated Red-winged Blackbird nests in eastern North Dakota. For some of the species observed, these observations represent the first documentation of predation on Red-winged Blackbird nests in the northern Great Plains.

Study Of Geometric Effects On Local Corrosion Rates For Lbe Loop, Chao Wu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Corrosion is an extremely important issue in nuclear cooling system applications. Many scientific and engineering efforts have been contributed to the research of finding an ideal material, which has resistance to corrosive Lead Bismuth Eutectic (LBE). A Delta Loop was designed and constructed in Los Alamos National Lab (LANL) to obtain the experimental data. This loop is a multi-section closed system that differs in diameter from one part to another. As a result, an intensive study on the geometry effect is hence necessary and valuable. In this thesis, this problem was simulated by commercial software STAR-CD. Results provide a good …

Requirement For The Betai And Betaiv Tubulin Isotypes In Mammalian Cilia., Heather C Jensen-Smith, Richard F Ludueña, Richard Hallworth

Journal Articles: Eppley Institute

Nielsen et al., [2001: Curr Biol 11:529-533], based on studies in Drosophila, have proposed that beta tubulin in axonemal microtubules must contain a specific acidic seven amino acid sequence in its carboxyl terminus. In mammals, the two betaIV isotypes (betaIVa and betaIVb) contain that sequence. In order to test the application of this hypothesis to mammals, we have examined the expression of beta tubulin isotypes in four different ciliated tissues (trachea, ependyma, uterine tube, and testis) using isotype-specific antibodies and indirect immunofluorescence. We find that betaIV tubulin is present in all ciliated cell types examined, but so is betaI tubulin. …

Fisheries Research Contract Report No. 2 - Towards An Assessment Of Natural And Human Use Impacts On The Marine Environment Of The Abrolhos Islands (Phase 1 : Data Consolidation And Scoping - Final Report For Frdc Project 2000/1 66), C. F. Chubb, K. Nardi

Fisheries Research Contract Reports

This project has drawn together existing research data relating to natural and human impacts on the Abrolhos Islands marine habitats. It has surveyed current uses of these habitats and placed anthropogenic impacts within the context of natural perturbations. Through public forum presentation and debate, this work has allowed real issues, not perceptions, to surface and be addressed properly. This was achieved by defining a strategic programme of research through a scientific workshop process involving all community stakeholders. A two volume Fisheries Research Report (WA) summarizes current knowledge and details the workshop proceedings and strategic research plan.

Drug Wars In Black And White, Joseph E. Kennedy

Law and Contemporary Problems

The debate over the racial complexion of the war against drugs often devolves into a clash of fundamental assumptions that are difficult to either validate or refute. Ultimately, however, the criminal justice system is destined to find crime only where it looks for crime.

Race, Crime, And Institutional Design, Erik Luna

Law and Contemporary Problems

Minorities are gravely overrepresented in every stage of the criminal process--from pedestrian and automobile stops, to searches and seizures, to arrests and convictions, to incarceration and capital punishment. While racial data can provide a snapshot of the current state of affairs, such information rarely satisfies questions of causation, and usually only sets the scene for normative theory.

Intellectual Freedom, David Moshman

Department of Educational Psychology: Faculty Publications

Intellectual development, the development of the intellect, is the emergence of increasingly sophisticated forms or levels of cognition, the progress of understanding, reasoning, and rationality. We can describe the outcomes of intellectual development by specifying steps, stages, or levels of development for cognition as a whole and/or for various cognitive domains. Fundamentally, however, intellectual development is an ongoing process of reflection, coordination, and social interaction that begins in early childhood and continues, at least in some cases, long into adulthood.
Liberal education, however defined, includes the promotion of intellectual development as a primary goal. There may be specific facts, skills, …

Population Monitoring In Support Of A Rabies Vaccination Program For Skunks In Arizona, Richard M. Engeman, Kevin L. Christensen, Michael J. Pipas, David L. Bergman

United States Department of Agriculture Wildlife Services: Staff Publications

Three population monitoring methods were evaluated in support of a trap/vaccinate/release program for controlling a bat variant of rabies virus in skunks (Mephitis mephitis) in Flagstaff, Arizona (USA). Skunks were the primary species targeted for population monitoring during the program, but feral cats were also monitored as they represented an abundant secondary vector species capable of rabies transmission. Skunks were vaccinated and released, except for a subset tested for rabies. All captured cats were placed in the local animal shelter. Spotlight surveys essentially did not detect skunks, and were not able to detect reductions in the cat population. …
