Designing A Monitoring Plan, Eric M. Gese, Hilary S. Cooley, Frederick F. Knowlton

United States Department of Agriculture Wildlife Services: Staff Publications

Monitoring is the collection and analysis of repeated observations or measurements ro determine whether a management action is having the desired effect of meeting management objectives and demonstrating success or failure of a management strategy (Elzinga et al 2001). Monitoring is composed of a series of surveys (sensu Chapter 2) framed in a design aimed at answering specific management questions. There are many reasons to establish monitoring plans, such as when a carnivore species is of a high social or economic value, is rare and decreasing in numbers, is in eminent danger of extinction, or is part of a …

Evaluation Of Elevated Bait Trays For Attracting Blackbirds (Icteridae) In Central North Dakota, George M. Linz, Jamison B. Winter, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Sunflower (Helianthus annuus L.) became an economically important crop in North Dakota in the 1970s, providing a major source of food for post-breeding blackbirds (Icteridae). Reducing local blackbird populations with rice grains treated with an avicide is one proposed alternative for reducing sunflower damage. In fall 2007 and 2008, we evaluated the idea of attracting blackbirds to rice-baited trays attached to wire cages supplied with live blackbirds. During our observations (1011 h), we saw 3888 birds, consisting of 25 species and 12 families, on the bait trays. Blackbirds made up 90.4% of the bird observations, whereas sparrows (Emberizidae) made …

Biology And Impacts Of Pacific Island Invasive Species. 8. Eleutherodactylus Planirostris, The Greenhouse Frog (Anura: Eleutherodactylidae), Christina A. Olson, Karen H. Beard, William C. Pitt

United States Department of Agriculture Wildlife Services: Staff Publications

The greenhouse frog, Eleutherodactylus planirostris, is a direct developing (i.e., no aquatic stage) frog native to Cuba and the Bahamas. It was introduced to Hawai‘i via nursery plants in the early 1990s and then subsequently from Hawai‘i to Guam in 2003. The greenhouse frog is now widespread on five Hawaiian Islands and Guam. Infestations are often overlooked due to the frog’s quiet calls, small size, and cryptic behavior, and this likely contributes to its spread. Because the greenhouse frog is an insectivore, introductions may reduce invertebrates. In Hawai‘i, the greenhouse frog primarily consumes ants, mites, and springtails and obtains …

A Novel Bipolar Electric Fence For Excluding White-Tailed Deer From Stored Livestock Feed, G. E. Phillips, M. J. Lavelle, Justin W. Fischer, Joshua J. White, Scott J. Wells, K. C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Where cattle (Bos taurus) and free-ranging white-tailed deer (Odocoileus virginianus) coexist, they frequently share space and resources, potentially resulting in damage to stores of livestock feed and risk of interspecies disease transmission. Preventing use of stored feed by deer can be an important objective in farm management, depending on amount of damage experienced and perceived risk of disease transmission. Woven wire fences (2.4 to 3.0 m high) are generally considered to be the most effective means for excluding deer. However, rapidly deployable temporary means of excluding deer could be useful, especially during late winter when deer …

Producer Survey Of Bird-Livestock Interactions In Commercial Dairies, Stephanie A. Shwiff, James C. Carlson, J. H. Glass, J. Suckow, Martin S. Lowney, K. M. Moxcey, Bruce Larson, George M. Linz

United States Department of Agriculture Wildlife Services: Staff Publications

The objective of this producer survey was to identify and estimate damage caused by bird-livestock interactions in commercial dairies. The interactions between birds and livestock have previously been implicated in causing economic damage while contributing to the environmental dissemination of microorganisms pathogenic to livestock and humans. Very little research exists to help producers understand what bird species use dairies, why they use dairies, or the scope and nature of damage created as a result of bird-livestock interactions. To better characterize these interactions, we surveyed dairy operators within Pennsylvania, New York, and Wisconsin. Survey results suggest that the most common and …

The Introduction, Impacts, And Management Of A Large, Invasive, Aquatic Rodent In The United States, Gary W. Witmer, Trevor R. Sheffels, Stephen R. Kendrot

United States Department of Agriculture Wildlife Services: Staff Publications

Marshes, both tidal and non-tidal, are productive and complex ecosystems. The water in these systems ranges from fresh, to brackish, to saline as one moves from inland to coastal areas. Marshes are an interface between upland and aquatic habitats, and many biotic and abiotic processes lead to increased species richness and diversity (Gedan et al., 2009). Marshes provide many ecological services, including recharge and discharge of ground water; water quality control; retention, removal, and transformation of nutrients; habitats for many floral and faunal species; biomass production and exports; flood control and storm buffering; and stabilization of sediments and slowing …

Estimates Of Energy And Prey Requirements Of Wolverines, Julie K. Young, Brian Hudgens, David K. Garcelon

United States Department of Agriculture Wildlife Services: Staff Publications

Wolverine (Gulo gulo) populations have decreased throughout much of their North American range and there is interest in establishing recovery programs in the Sierra Nevada of California and the Rocky Mountains of Colorado. Determining the sufficiency of prey resources is an important consideration for initiating wolverine recovery, yet there are limited data on resource availability and needs. Our goal is to estimate prey requirements based on wolverine caloric needs and the caloric content of prey likely to be available. We achieve this goal by modifying existing models to account for wolverine biology. Models show a male wolverine requires …

Cow Dogs: Use Of Livestock Protection Dogs For Reducing Predation And Transmission Of Pathogens From Wildlife To Cattle, Kurt C. Vercauteren, Michael J. Lavelle, Thomas M. Gehring, Jean-Marc Landry

United States Department of Agriculture Wildlife Services: Staff Publications

Dogs have been employed to protect an array of resources from various species of offending wildlife. Historically, livestock protection dogs (LPDs) protected domestic sheep and goats from predators based on development of a strong bond between protected and protector. Within reason, developing that bond between a LPD and other species of livestock should be achievable. We conducted several studies in which we raised and bonded LPDs with bovine calves and evaluated them for protecting cattle in a variety of settings. Though successful strategies in developing LPDs to protect cattle were similar to those established for sheep, we found differences that …

The Direction Of Research And Management Of Double-Crested Cormorants Heading Into The 2000s: Symposium Overview And Future Information Needs, Brian S. Dorr, Christopher Somers

An overview is provided of a symposium on the direction of research and management of double-crested cormorants (Phalacrocorax auritus) heading into the 2000s. The current symposium built on previous efforts and described a number of focus areas of informational need, including cormorant impacts on natural resources, demographics of cormorants, assessment of control efforts, assessment of fish consumption and bioenergetics, and cormorant spatial ecology and influences on movements. The cormorant symposium highlighted a shift in research focus relative to earlier symposia, from evaluating potential impacts on commercial and natural resources to evaluating management actions in attaining desired goals. In …

Rats! Foiled Again: A History Of Rodent Control Methods Development At The National Wildlife Research Center, Kathleen A. Fagerstone, Michael W. Fall, Gary W. Witmer, William C. Pitt

United States Department of Agriculture Wildlife Services: Staff Publications

The National Wildlife Research Center (NWRC) and its predecessor laboratories have a long history of developing materials and methods for managing rodents and the damage they cause. The NWRC has been influential in exploring, developing, and maintaining legal uses of many traditional field rodenticides such as strychnine and zinc phosphide. Products have been developed for managing rodents in a variety of locales, and for managing a variety of species, from commensal rodents in urban areas, to pocket gophers and mountain beaver in forests, prairie dogs and ground squirrels on rangelands, and nutria and beaver in wetlands. Considerable research has also …

Bird Management In Fruit Crops: How We Make Progress, Catherine A. Lindell, Stephani A. Shwiff, Phillip H. Howard

United States Department of Agriculture Wildlife Services: Staff Publications

Fruit producers have identified bird damage as a critical issue that has received limited attention from researchers. A USDA study estimated that birds cost producers in 7 states tens of millions of dollars through fruit loss and management efforts. Despite these costs, research has been uncoordinated and piecemeal, leaving producers with few, well-tested management options. We describe several objectives to strive for in order to achieve the goal of providing producers with region-specific, cost-effective, and environmentally sustainable bird management strategies. These objectives include 1) quantifying economic consequences of bird damage for producers, consumers, and regional economies, and determining costs and …

Effects Of Turf Rolling And Soil Aeration On Rodent Populations, Gary W. Witmer, David Borrowman

United States Department of Agriculture Wildlife Services: Staff Publications

Rodent populations at airports can cause human safety issues by attracting raptors which increases the risk of raptor-aircraft strikes. Various methods can be used to reduce rodent numbers, including trapping, poisoning, and habitat manipulation. Burrow disruption by turf rolling and soil aeration is a potential habitat manipulation method that could potentially reduce the carrying capacity for rodents. We tested this method at Kansas City International Airport, Missouri. We monitored the rodent populations in a control (untreated) area and in a nearby treated area where the turf was rolled and the soil aerated. We used grids of live traps to determine …

Rodent Burrow Systems In North America: Problems Posed And Potential Solutions, Gary W. Witmer, Rachael S. Moulton, Jenna L. Swartz

United States Department of Agriculture Wildlife Services: Staff Publications

Many rodent species are effective burrowers. In North America, these include species of ground squirrels, prairie dogs, marmots, and pocket gophers. The burrow systems of other species of rodents such as voles and mice are less elaborate and pose less potential for direct damage. Burrowing abilities, coupled with other characteristics (e.g., prolific, adaptable, ever-growing incisors for gnawing), can result in many types and amounts of impacts to human resources and ecosystems. Damage occurs to levees, roadbeds, buried pipes and cables, intrusion to sensitive areas (such as military sites, capped hazardous waste burial sites), vegetation effects, effects on water infiltration/runoff, and …

An Assessment Of Richardson’S Ground Squirrel Activity And Potential Barriers To Limit Access To Sensitive Sites At Malmstrom Air Force Base, Montana, Gary W. Witmer, Rachael Moulton, Jenna Swartz, Jason Gibbons

United States Department of Agriculture Wildlife Services: Staff Publications

Small mammals pass through or under chain link security fences, triggering sensors and undermining facility infrastructure at sensitive military sites. Traditional methods of rodent control are not practical because of the vastness of land to be maintained with limited manpower. Permanent barriers (above and below ground) and low-maintenance, long-term bait stations offer potential permanent and cost-effective solutions to mitigate rodent intrusions. We assessed Richardson’s ground squirrel populations, activities, and burrows at Malmstrom Air Force Base, MT. We also conducted preliminary barrier trials in the outdoor rodent buildings of the USDA National Wildlife Research Center in Fort Collins, CO. Ground squirrels …

Synthesis And Investigation Of The Liquid Crystalline Properties Of Polycyclic Aromatic Hydrocarbons, Joseph A. Paquette

Theses and Dissertations (Comprehensive)

In this thesis, the synthesis and liquid crystalline properties of a series of novel substituted dibenz[a,c]anthracenes is reported. Specifically, a series of hexaalkoxydibenz[a,c]anthracenes were prepared and found not to exhibit a mesophase. In contrast, when substituents are introduced on the aromatic core, columnar mesophases are observed over broad temperature ranges. A series substituted derivatives was prepared and their mesomorphic properties compared. In general, electron-withdrawing substituents promote broad mesophase temperature ranges, as do larger substituents. The liquid crystalline phase is a result of the electronic effects, size and shape of the substituents in the 10 and 13 positions.

We also synthesized …

Atr-Ftir Studies On The Kinetics Of Dimethylarsinic Acid (Dma) Surface Complexation With Iron(Oxyhydr)Oxides, Julia Tofan-Lazar Miss

Theses and Dissertations (Comprehensive)

Dimethylarsinic acid (DMA) is an organoarsenical compound that, along with monomethylarsonic acid, poses a health and an environmental risk, and a challenge to the energy industry. Little is known about the surface chemistry of DMA at the molecular level with materials relevant to geochemical environments and industrial sectors. The surface chemistry of phosphorus and arsenic compounds in their organic and inorganic forms is of great interest due to its role in controlling their transport, bioaccessibility and speciation. This thesis reports the first in-situ and surface-sensitive rapid kinetic studies on the adsorption and desorption of DMA to and from Fe-(oxyhydr)oxide films …

Books And Websites, E-Journals Or Print: If The Source Fits, Use It, Todd J. Wiebe

Faculty Publications

Despite the ever-growing range of media types, formats, and information-access options, students are often instructed to only use specific sources in their research. They are sometimes even given strict guidelines, prescribing how many of each they need to, or may, cite. It is important not to lead students to believe there is a formula for the ideal works cited for all research topics. In contrast, students should learn to think critically about the content and appropriateness of each potential source rather than choosing it only because it is a book, a journal article, a Website, etc. This article argues that …

A Critical Review Of The Mandatory Reporting Protocol, Elayne M. Tanner

Theses and Dissertations (Comprehensive)

Mandatory reporting, although originally enacted to serve the single purpose of protecting vulnerable children from abuse, has been considered for ever expanding purposes. As a policy stance, mandatory reporting is frequently considered to support those socially sanctioned behavioural standards developed to regulate social institutions such as marriage, child rearing, aging and work. Although always embracing an inherent element of protection, a careful balance must be negotiated because mandatory reporting obligations also risk compromising the very rights that are the cornerstones of the social work profession, those of autonomy, confidentiality and self-determination. This research explored the mandatory reporting protocol specifically questioning …

Enhancing Elementary School Prevention Program Implementation Through Influential Contextual Factors, Alice Schmidt Hanbidge

Theses and Dissertations (Comprehensive)

A current gap in the literature exists with regard to formulating a holistic view of contextual factors involved in school-based prevention programming implementation. The purpose of this grounded theory study is to further explore how multilevel ecological and cross-system factors influence prevention program implementation. This study builds on development of a theory to guide the practices for preventive program implementation with fidelity. The Integrated Program (IP) conceptual framework, initiated in an earlier paper (Schmidt Hanbidge, 2009) identified key program contextual and motivational factors that critically influence prevention program implementation. Taken from an ecological perspective, the IP framework incorporates multi-levels of …

A Geophysical Investigation Of The Northeastern Rim Of The St. Martin Impact Structure, Manitoba, Canada., Vladimir B. Zivkovic

Theses and Dissertations

The St. Martin impact structure is a 40 Km diameter structure located in Manitoba, Canada lies in featureless, glaciated terrain lacking any surface expression of an impact structure. The age of the structure has been re-determined to range between 224.3 Ma to 241.4 Ma which nullified a previous hypothesis suggesting this impact was part of a multiple impact event. Within the proposed structural boundary two outcrops of Archean granite are present. The first outcrop is located in what has been identified as the central peak of the impact structure. The second outcrop lies along the northeastern boundary and is known …

Multisite Recruitment And Data Collection Among Older Adults : Exploring Methods To Conserve Human And Financial Resources., Valerie Lander Mccarthy, Karen Cassidy

Faculty and Staff Scholarship

The purpose of this article is to describe strategies that were effective in recruitment and data collection among older adults in 3 quantitative studies while decreasing costs in terms of time and money. Factors effective in reducing use of investigators' time and expenses included limiting exclusion of data because of abnormal Mini-Cog scores by careful initial screening and avoiding repeated reminders or follow-up, collecting data in small groups, collapsing consent, dementia screening, and data collection into single sessions, as well as accommodating for sensory and literacy deficits. The cross-sectional, descriptive studies were conducted among community-dwelling older adults attending senior citizen …

Moderate-Intensity Exercise Improves Body Composition And Improves Physiological Markers Of Stress In Hiv-Infected Men, Wesley Dudgeon, Jason R. Jaggers, Kenneth D. Phillips, Larry Durstine, Stephanie Burgess, George William Lyerly, John Mark Davis, Gregory Alan Hand

Faculty and Staff Scholarship

HIV/AIDS and its treatment often alter body composition and result in poorer physical functioning. The aim of this study was to determine the effects of a moderate-intensity exercise program on body composition and the hormones and cytokines associated with adverse health outcomes. HIV-infected males (N = 111) were randomized to an exercise group (EX) who completed 6 weeks of moderate-intensity exercise training, or to a nonintervention control group (CON). In pre- and postintervention, body composition was estimated via DXA, peak strength was assessed, and resting blood samples were obtained. There was a decrease in salivary cortisol at wake (P = …

Deconstructing Events: The Neural Bases For Space, Time, And Causality, Alexander Kranjec, Eileen R. Cardillo, Gwenda L. Schmidt, Matthew Lehet, Anjan Chatterjee

Faculty Publications

Space, time, and causality provide a natural structure for organizing our experience. These abstract categories allow us to think relationally in the most basic sense; understanding simple events requires one to represent the spatial relations among objects, the relative durations of actions or movements, and the links between causes and effects. The present fMRI study investigates the extent to which the brain distinguishes between these fundamental conceptual domains. Participants performed a 1-back task with three conditions of interest (space, time, and causality). Each condition required comparing relations between events in a simple verbal narrative. Depending on the condition, participants were …
