Landslide Ecology, Lawrence R. Walker, Aaron B. Shiels

United States Department of Agriculture Wildlife Services: Staff Publications

Despite their often dangerous and unpredictable nature, landslides provide fascinating templates for studying how soil organisms, plants, and animals respond to such destruction. The emerging field oflandslide ecology helps us to understand these responses, aiding slope stabilization and restoration and contributing to progress made in geological approaches to landslide prediction and mitigation. Summarizing the growing body ofliterature on the ecological consequences of landslides, this book provides a framework for the promotion of ecological tools in predicting, stabilizing, and restoring biodiversity to landslide scars at both local and landscape scales. It explores nutrient cycling; soil development; and how organisms disperse, colonize, …

Oral Rabies Vaccination Variation In Tetracycline Biomarking Among Ohio Raccoons, Timothy P. Algeo, Gary Norhenberg, Robert Hale, Andrew Montoney, Richard B. Chipman, Dennis Slate Jan 2013

Oral Rabies Vaccination Variation In Tetracycline Biomarking Among Ohio Raccoons, Timothy P. Algeo, Gary Norhenberg, Robert Hale, Andrew Montoney, Richard B. Chipman, Dennis Slate

United States Department of Agriculture Wildlife Services: Staff Publications

Oral rabies vaccination (ORV) programs have traditionally relied on tetracycline marking as an index to bait uptake. Whether tetracycline serves well in this capacity depends on its deposition affinity and ability to be detected consistently among tissues selected for analysis from target species. We evaluated samples from 760 hunter-harvested raccoons (Procyon lotor) from areas in Ohio where ORV had been conducted during 1998, 1999, and 2001. Tetracycline marking was evaluated within and among first premolar (PM1), second premolar (PM2), and canine (CN) teeth, and mandibular bone (MB) by side (left versus right); and by tissue type. Tetracycline detection ranged from …

Intraguild Relationships Between Sympatric Predators Exposed To Lethal Control: Predator Manipulation Experiments, Benjamin L. Allen, Lee R. Allen, Richard M. Engeman, Luke K.-P. Leung Jan 2013

Intraguild Relationships Between Sympatric Predators Exposed To Lethal Control: Predator Manipulation Experiments, Benjamin L. Allen, Lee R. Allen, Richard M. Engeman, Luke K.-P. Leung

United States Department of Agriculture Wildlife Services: Staff Publications

Introduction: Terrestrial top-predators are expected to regulate and stabilise food webs through their consumptive and non-consumptive effects on sympatric mesopredators and prey. The lethal control of top-predators has therefore been predicted to inhibit top-predator function, generate the release of mesopredators and indirectly harm native fauna through trophic cascade effects. Understanding the outcomes of lethal control on interactions within terrestrial predator guilds is important for zoologists, conservation biologists and wildlife managers. However, few studies have the capacity to test these predictions experimentally, and no such studies have previously been conducted on the eclectic suite of native and exotic, mammalian and reptilian …

Population Management To Reduce The Risk Of Wiid Life-Aircraft Collisions, Richard A. Dolbeer, Alan B. Franklin Jan 2013

Population Management To Reduce The Risk Of Wiid Life-Aircraft Collisions, Richard A. Dolbeer, Alan B. Franklin

United States Department of Agriculture Wildlife Services: Staff Publications

Pour basic control strategies mitigate the risks to aviation caused by wildlife at airports: (1) aircraft flight schedule modification (primarily at military air· bases) and enhancement of aircraft visibility to avoid interactions with wildlife (e.g., Blackwell et a1. 2009b, 2012); (2) habitat modification and elimination of food, water, and cover that attract wildlife (Cleary and Dolbeer 2005, Blackwell et al. 2009a; Chapters 5, 8-10); (3) repellent and harassment techniques to disperse wild life (Cleary and Dolbeer 2005; Chapters 2-4); and (4) wildlife population management (e.g., Dolbeer 1998). As discussed throughout this book, successful efforts to mitigate the risk of wildlife-aircraft …

Understanding Animal Movements At And Near Airports, Jerrold L. Belant, Brian E. Washburn, Travis L. Devault Jan 2013

Understanding Animal Movements At And Near Airports, Jerrold L. Belant, Brian E. Washburn, Travis L. Devault

United States Department of Agriculture Wildlife Services: Staff Publications

Understanding movements of hazardous wildlife species at and near airports is critical to formulating effective management strategies for reducing aviation risk. Animal movements vary daily, seasonally, and annually and are based on broad biological and ecological concepts, including foraging, reproduction, habitat characteristics, dispersal, and migration. As an energy conservation strategy. most animals minimize their movements to meet life requisites, which in turn presumably improves fitness. Animal movements in relation to airports can be direct; for example, Canada geese (Branta canadensis) flying onto an airfield because grass height and composition are suitable for loafing sites and as food. Animal …

Brownian Bridge Movement Models To Characterize Birds’ Home Ranges, Justin W. Fischer, W. David Walter, Michael L. Avery Jan 2013

Brownian Bridge Movement Models To Characterize Birds’ Home Ranges, Justin W. Fischer, W. David Walter, Michael L. Avery

United States Department of Agriculture Wildlife Services: Staff Publications

A Brownian bridge movement model (BBMM) is a relatively new concept that estimates the path of an animal’s movement probabilistically from data recorded at brief intervals. A BBMM assumes that locations are not independent, whereas the “classical” kernel-density estimator (KDE) assumes they are. We estimated BBMM home ranges for 11 Black Vultures (Coragyps atratus) and 7 Turkey Vultures (Cathartes aura) equipped with satellite transmitters near Marine Corps Air Station Beaufort, South Carolina, from October 2006 to November 2008. The 95% BBMM home ranges (95% BBMM) of the two Black Vultures that traveled >100 km from the …

Avian Influenza Infection Alters Fecal Odor In Mallards, Bruce A. Kimball, Kunio Yamazaki, Dennis Kohler, Richard A. Bowen, Jack P. Muth, Maryanne Opiekun, Gary K. Beauchamp

United States Department of Agriculture Wildlife Services: Staff Publications

Changes in body odor are known to be a consequence of many diseases. Much of the published work on disease-related and body odor changes has involved parasites and certain cancers. Much less studied have been viral diseases, possibly due to an absence of good animal model systems. Here we studied possible alteration of fecal odors in animals infected with avian influenza viruses (AIV). In a behavioral study, inbred C57BL/6 mice were trained in a standard Y-maze to discriminate odors emanating from feces collected from mallard ducks (Anas platyrhynchos) infected with low-pathogenic avian influenza virus compared to fecal odors …

Ecology Of Zoonotic Infectious Diseases In Bats: Current Knowledge And Future Directions, D. T. S. Hayman, R. A. Bowen, P. M. Cryan, G. M. Mccracken, T. J. O'Shea, A. J. Peel, A. T. Gilbert, C. T. Webb, J. L. N. Wood

United States Department of Agriculture Wildlife Services: Staff Publications

Bats are hosts to a range of zoonotic and potentially zoonotic pathogens. Human activities that increase exposure to bats will likely increase the opportunity for infections to spill over in the future. Ecological drivers of pathogen spillover and emergence in novel hosts, including humans, involve a complex mixture of processes, and understanding these complexities may aid in predicting spillover. In particular, only once the pathogen and host ecologies are known can the impacts of anthropogenic changes be fully appreciated. Cross-disciplinary approaches are required to understand how host and pathogen ecology interact. Bats differ from other sylvatic disease reservoirs because of …

Pheromonal Control Of The Invasive Brown Treesnake: Potency Of Female Sexual Attractiveness Pheromone Varies With Ovarian State, Tom Mathies, Breanna Levine, Richard M. Engeman, Julie A. Savidge

United States Department of Agriculture Wildlife Services: Staff Publications

The female sex pheromone has potential a s a control tool for the Brown Treesnake, Boiga irregularis Merrem, a pest introduced into Guam. We conducted male-guided bioassays to determine whether potency of the female pheromone varied according to reproductive state and during vitellogenesis. In weekly simultaneous choice tests, we presented males with skin lipid samples from vitellogenic females, non-vitellogenic females, conspecific males, and carrier controls. The total time each sample was tongue-flicked was recorded: mean total tongue-flick time was highest for samples from vitellogenic females followed by samples from non-vitellogenic females. Pair-wise comparisons of male tongue-flick time for samples of …

Feral Swine Brucellosis In The United States And Prospective Genomic Techniques For Disease Epidemiology, Owen P. Leiser, Joseph L. Corn, Brandon S. Schmit, Paul S. Keim, Jeffrey T. Foster Jan 2013

Feral Swine Brucellosis In The United States And Prospective Genomic Techniques For Disease Epidemiology, Owen P. Leiser, Joseph L. Corn, Brandon S. Schmit, Paul S. Keim, Jeffrey T. Foster

United States Department of Agriculture Wildlife Services: Staff Publications

Brucellosis is a common infection of feral swine throughout the United States. With the recent expansion of feral swine populations across the country, this disease poses an increasing threat to agriculture and hunters. The standard approach to Brucella surveillance in feral swine has been serological testing, which gives an indication of past exposure and is a rapid method of determining populations where Brucella is present. More in-depth analyses require bacterial isolation to determine the Brucella species and biovar involved. Ultimately, for a comprehensive understanding of Brucella epizootiology in feral swine, incorporation of genotyping assays has become essential. Fortunately, the past …

United States Department of Agriculture Wildlife Services: Staff Publications

Little is known about movements and habitat use of Brown Pelicans (Pelecanus occidentalis) in the northern Gulf of Mexico. We attached satellite transmitters to 18 adult Brown Pelicans (nine males, nine females) that were captured on Grand Isle along the Louisiana coast during 31 August-2 September 2010. Their movements and habitat use were tracked between September 2010 and March 2012. Nine of the Brown Pelicans remained proximate to the Louisiana coast; four ranged along the coasts of Alabama, Mississippi, and Louisiana; three moved from Louisiana to Texas; and two migrated across the Gulf of Mexico to the Yucatan Peninsula. …

Failure Of Transmission Of Low-Pathogenic Avian Influenza Virus Between Mallards And Freshwater Snails: An Experimental Evaluation, Paul T. Oesterle, Kathryn P. Huyvaert, Darcy Orahood, Nicole Mooers, Heather Sullivan, Alan B. Franklin, J. Jeffrey Root

United States Department of Agriculture Wildlife Services: Staff Publications

In aquatic bird populations, the ability of avian influenza (AI) viruses to remain infectious in water for extended periods provides a mechanism that allows viral transmission to occur long after shedding birds have left the area. However, this also exposes other aquatic organisms, including freshwater invertebrates, to AI viruses. Previous researchers found that AI viral RNA can be sequestered in snail tissues. Using an experimental approach, we determined whether freshwater snails (Physa acuta and Physa gyrina) can infect waterfowl with AI viruses by serving as a means of transmission between infected and naı¨ve waterfowl via ingestion. In our …

Twenty Years Of Immunocontraceptive Research: Lessons Learned, Lowell A. Miller, Kathleen A. Fagerstone, Douglas C. Eckery Jan 2013

Twenty Years Of Immunocontraceptive Research: Lessons Learned, Lowell A. Miller, Kathleen A. Fagerstone, Douglas C. Eckery

United States Department of Agriculture Wildlife Services: Staff Publications

The National Wildlife Research Center (NWRC) began immunocontraception vaccine research by testing porcine zona pellucida (PZP) on white-tailed deer (Odocoileus virginianus). Early PZP research demonstrated that PZP induced infertility; however, increased length of the rut was observed in PZP-treated deer. An alternative vaccine using a keyhole limpet hemocyanin-gonadotropin-releasing hormone (KLH-GnRH) conjugate formulated with modified Freund’s adjuvant was developed at NWRC. Suppression of GnRH has reduced reproduction in both sexes but is most effective in females. This vaccine was effective in preventing contraception in female deer for several years after a prime and boost. Due to adverse side effects …

Effects Of Black-Tailed Deer And Roosevelt Elk Herbivory In Intensively Managed Douglas-Fir Plantations, Jimmy D. Taylor Ii Jan 2013

Effects Of Black-Tailed Deer And Roosevelt Elk Herbivory In Intensively Managed Douglas-Fir Plantations, Jimmy D. Taylor Ii

United States Department of Agriculture Wildlife Services: Staff Publications

Black-tailed deer and Roosevelt elk are found throughout conifer-dominated Pacific Northwest forests west of the Cascade Crest, where they are important aesthetically, culturally, ecologically, and recreationally. Throughout their annual cycles, deer and elk use a variety of forest types and age classes to meet their basic requirements: food, water, cover, breeding, and young-rearing. Although their foraging strategies differ, black-tailed deer (browsers) and Roosevelt elk (grazers) often use the same forests. In general, forage plants for deer and elk are shade intolerant and are stimulated to grow when exposed to direct sunlight. As such, deer and elk often use clearcut patches …

Wildlife In Managed Forests: An Overview Of Perspectives From The Pacific Northwest, Jimmy D. Taylor Ii Jan 2013

Wildlife In Managed Forests: An Overview Of Perspectives From The Pacific Northwest, Jimmy D. Taylor Ii

United States Department of Agriculture Wildlife Services: Staff Publications

1. Introduction- Humans rely on forests for fiber, food, water, shelter, recreation, inspiration, and various other benefits. Similarly, many species of native fauna depend on forests to meet their seasonal and annual requirements. Forests in the Pacific Northwest have a longstanding history of providing high quality forest products, and ownership across a complex matrix of forest stands is divided among provincial, federal, state, tribal, and private entities. Over time, requirements to provide forest products have increasingly rested with industrial and non-industrial private landowners. Concomitantly, forest management has evolved and intensified on private lands in response to increases in national and …

Landslides Cause Spatial And Temporal Gradients At Multiple Scales In The Luquillo Mountains Of Puerto Rico, Aaron B. Shiels, Lawrence R. Walker Jan 2013

Landslides Cause Spatial And Temporal Gradients At Multiple Scales In The Luquillo Mountains Of Puerto Rico, Aaron B. Shiels, Lawrence R. Walker

United States Department of Agriculture Wildlife Services: Staff Publications

Landslides represent one of the most severe disturbances in montane forests because the main consequence of their occurrence is loss or downslope redistribution of the majority of the above- and below-ground biomass. We examined among-landslide gradients (size, slope, aspect, age, elevation) on 142 landslides in the Luquillo Mountains, Puerto Rico, created by three storms in 2003–2004. We also examined within-landslide gradients (top to bottom, edge to center, successional development) by reviewing 20 yr of landslide data in the Luquillo Mountains. Landslide abundance and plant successional patterns do not closely reflect the elevation gradient that is characteristic of this mountain range, …

Estimating Prion Adsorption Capacity Of Soil By Bioassay Of Subtracted Infectivity From Complex Solutions (Basics), A. Christy Wyckoff, Krista L. Lockwood, Crystal Meyerett-Reid, Brady A. Michel, Heather Bender, Kurt C. Vercauteren, Mark D. Zabel

United States Department of Agriculture Wildlife Services: Staff Publications

Prions, the infectious agent of scrapie, chronic wasting disease and other transmissible spongiform encephalopathies, are misfolded proteins that are highly stable and resistant to degradation. Prions are known to associate with clay and other soil components, enhancing their persistence and surprisingly, transmissibility. Currently, few detection and quantification methods exist for prions in soil, hindering an understanding of prion persistence and infectivity in the environment. Variability in apparent infectious titers of prions when bound to soil has complicated attempts to quantify the binding capacity of soil for prion infectivity. Here, we quantify the prion adsorption capacity of whole, sandy loam soil …

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife reservoir hosts of bovine tuberculosis (bTB) include Eurasian badgers (Meles meles) and brushtail possum (Trichosurus vulpecula) in the UK and New Zealand, respectively. Similar species warrant further investigation in the northern lower peninsula of Michigan, USA due to the continued presence of bTB on cattle farms. Most research in Michigan, USA has focused on interactions between white-tailed deer (Odocoileus virginianus) and cattle (Bos taurus) for the transmission of the infectious agent of bTB, Mycobacterium bovis, due to high deer densities and feeding practices. However, limited data are available on medium-sized …

Open Field Test With Avipel Bird Repellent: Year I, Megan Niner, George M. Linz, Jeffrey Homan, Mark Clark

United States Department of Agriculture Wildlife Services: Staff Publications

Since the mid-1900s, blackbird depredation has become an expensive problem for farmers in the Great Plains region of the United States and Canada (Blackwell et al. 2003). Damage to crops from blackbirds costs the growers of sunflower millions annually (Peer et al. 2003). The problem stems from two concurrent events: ripening of sunflowers and fledging of millions of resident blackbirds that must quickly prepare for migration to southern wintering grounds. Multiple methods of protecting crops exist, but none have proved to be cost-effective. For this reason and the safety of the non-target species, a chemical-based repellent might be a good …

Called To Lead: An Examination Into The Phenomenon Of Calling, Hughie Jackson Barnes Jan 2013

Called To Lead: An Examination Into The Phenomenon Of Calling, Hughie Jackson Barnes

Theses and Dissertations

Perhaps the most widely known episode of a calling is the burning bush experience of Moses, leader of Israel's sojourn to freedom from Egyptian captivity. At present, the phenomenon of being called to a place, vocation, or career has limited social science research. Indeed, prior to the middle of the 21st century this concept was lacking both theoretically and empirically. Any coverage of the subject of a calling was primarily found in religious periodicals and similar publications (Newman, 2006). In 2007, Scott attempted to advance the discourse on career development by examining callings and the corollary meanings which college students …

Examining The Effects Of Leader Social Intelligence On Employee Engagement, Josh Dazel Jan 2013

Examining The Effects Of Leader Social Intelligence On Employee Engagement, Josh Dazel

Theses and Dissertations

This study evaluated the effects of leader social intelligence (SI) on employee engagement (EE) by measuring 36 leaders' SI and interviewing 10 leaders. Although managers were rated as utilizing SI competencies, there were no direct relationships with follower EE ratings. Findings suggested that Empathy may be the most effective SI for EE. Findings suggested that the SI competency of Teamwork also may have some impact. Mixed support was generated for the other five SIs. Support was inconclusive regarding direct relationships between leader SI and EE. However, 17 leaders with the highest EE scores exhibited significant relationships between EE and the …

Expressions Of Social Support: A Qualitative Analysis Of Psychotherapy With Clients Who Have Experienced Trauma, Celine F. Crespi-Hunt Jan 2013

Expressions Of Social Support: A Qualitative Analysis Of Psychotherapy With Clients Who Have Experienced Trauma, Celine F. Crespi-Hunt

Theses and Dissertations

One commonly accepted protective factor, social support, is hypothesized to be both helpful and harmful following exposure to traumatic events (Bonanno, 2008; Ellis, Nixon, & Williamson, 2009; Lyons, 1991). Although at least 10 theoretical models have been proposed to explain the relationship between social support and post-traumatic responses, existing theories do not adequately capture the multidimensional experience of social support, which is comprised of several constructs and structures (e.g., received and perceived support; support functions and content). Moreover, existing social support theories have not been studied in research related to therapy with traumatized clients. The present study, therefore, examined how …

On Humor And Healing: A Qualitative Analysis Of Expressions Of Humor In Therapy With Clients Who Have Experienced Trauma, Rebecca Rutchick Jan 2013

On Humor And Healing: A Qualitative Analysis Of Expressions Of Humor In Therapy With Clients Who Have Experienced Trauma, Rebecca Rutchick

Theses and Dissertations

From a positive psychology perspective, humor can be viewed as an adaptive strength, an important aspect of holistic health, and a potentially beneficial coping mechanism in the face of stressful or traumatic events. Existing research generally supports the idea that individuals can manage threatening situations by turning them into something that can be laughed at, although the effectiveness of such humor use is dependent on contextual factors and the specific forms of humor that are used (e.g., aggressive versus benign humor). However, there is minimal research on how trauma survivors actually express humor in therapy, particularly in the context of …

African American Female Leaders: Resilience And Success, Shanetta Weatherspoon-Robinson Jan 2013

African American Female Leaders: Resilience And Success, Shanetta Weatherspoon-Robinson

Theses and Dissertations

Women make up half of the workforce in America. Despite this, in traditional organizations, leadership roles are overwhelmingly held by men. Of the small number of African American women employed in the workforce, 30% hold professional or management positions and women in general are more educated, qualified and transformational than their male counterparts. Despite this, African American female leaders experience organizational barriers, social labeling, and biases driven by their intersectionality that hinders their career opportunities. Black feminist research suggests that social norms place women in subordinate roles in comparison to men in society. African American women face such social barriers …
