Multiple-Use Management Of Western U.S. Rangelands: Wild Horses, Wildlife, And Livestock, Rick E. Danvir

Human–Wildlife Interactions

Since 1959, the U.S. Congress has legislated the treatment and management of wild horses (Equus ferus caballus ) and burros (E. asinus ; WHB). While the legislation has ensured WHB a place as western rangeland icons, subsequent congressional actions, in response to public lobbying, have limited federal managers’ ability to manage WHB populations under the U.S. public land multiple-use doctrine. Federal land managers tasked with managing for multiple and competing interests on public lands of the western United States must not only consider WHB habitat requirements, but also wildlife species diversity and livestock grazing. Developing multiple-use management strategies while fulfi …

A Review Of Economic Studies Relating To The Bureau Of Land Management's Wild Horse And Burro Program, Paul M. Jakus

Human–Wildlife Interactions

This paper reviews literature addressing the benefits and costs of the Bureau of Land Management’s Wild Horse and Burro (WHB) Program. Within the framework of a comprehensive benefit cost analysis of the WHB Program, I find that program cost estimates are readily available from numerous sources. A more limited set of estimates of the opportunity cost of WHB on the range is available, as is a single estimate of the benefits provided by animal adoption. In contrast, there are no economic estimates of ecological damages caused by WHB in excess of the Appropriate Management Level, nor does a search of …

Consequences Of Porcine Zona Pellucida Immunocontraception To Feral Horses, Cassandra M.V. Nuñez

Human–Wildlife Interactions

Porcine zona pellucida (PZP) immunocontraception was developed to provide a more humane, effective, and inexpensive method of population regulation for wildlife species. It has been used to regulate populations of several species including white tailed deer (Odocoileus virginianus), elk (Cervus elaphus ), black bear (Ursus americanus ), and the feral horse (Equus ferus caballus) with varying levels of success. Early studies on Assateague Island National Seashore, Maryland, USA, suggested PZP was as an ideal form of fertility control because it reduced the likelihood of conception to

Wild Horse Demography: Implications For Sustainable Management Within Economic Constraints, Robert A. Garrott

Human–Wildlife Interactions

Management of wild horse (Equus ferus caballus ) populations on western U.S. rangelands has been a challenge since horses were given legal protection through the passage of the Wild Free-Roaming Horses and Burros Act (WFRHBA) in 1971. Horses have no eff ective predators, and unmanaged populations can double in 4–5 years and triple in 6–8 years. In order to meet the multiple-use paradigm for managing public rangelands, the Bureau of Land Management (BLM) has limited horse population growth through the periodic capture and removal of animals. While the WFRHBA mandates disposal of captured horses through placement into private ownership and …

Physiological Responses In Reindeer To The Application Of A Conducted Electrical Weapon, Camilla L. Lieske, Kimberlee B. Beckmen, Larry L. Lewis

Human–Wildlife Interactions

Conducted Electrical Weapons (CEWs) have potential as effective alternatives to chemical restraint for short-term non-routine capture and handling as well as aversion hazing of wildlife. To assess immediate and delayed physiologic effects of exposure to a CEW, we assigned 15 captive reindeer (Rangifer tarandus tarandus) to one of three treatment groups: immobilized with carfentanil and xylazine (CX), 10 second exposure to a CEW, or exposure to the CEW while immobilized with CX (CEW+CX). Blood samples were collected pre-treatment, immediately post-intervention, 10 min, 20 min, 4 hours, and 24 hours post-intervention. Physiologic effects were evaluated by analysis of blood, …

Toward Sustainable Conservation And Management Of Human-Wildlife Interactions In The Mmadinare Region Of Botswana: Villagers’ Perceptions On Challenges And Prospects, Oitshepile M. Modise, Rebecca Nthogo Lekoko, Olekae Tsompi Thakadu, Masego Ayo Mpotokwane

Human–Wildlife Interactions

Human–wildlife conflicts are increasing globally. The increase in conflicts has been attributed to growing human and wildlife populations and a per capita increase in the consumption of natural resources. In Botswana, conflicts between humans and elephants (Loxodonta africana) are increasing. The growing human population (2.2 million) is encroaching on the animals’ already restricted range. Concomitantly, more elephants are adversely affecting arable agriculture production. To better understand the magnitude and intensity of human–wildlife interactions with elephants and other native wildlife species in Botswana, we collected data through community forum conducted July 17–18, 2017 at a “Kgotla” meeting in Mmadinare, a village …

Cooperative Extension Agents As Key Informants In Assessing Wildlife Damage Trends In Georgia, Rhianna R. Hohbein, Michael T. Mengak

Human–Wildlife Interactions

To manage emerging human-wildlife conflicts, wildlife managers will require more information regarding trends in wildlife damage and public perceptions of control measures. In 2017, we administered an online survey to Georgia Agriculture and Natural Resource County Cooperative Extension Agents (ANR Agents) to assess the types of inquiries or complaints about nuisance wildlife they had received during the previous year. We asked questions about the common species creating problems, the nature of the damage reported, and perceptions of client preferences regarding different types of nuisance wildlife control. We compared the results of our 2017 survey to a similar survey conducted in …

Portable Electric Fencing For Bear Deterrence And Conservation, Tom S. Smith, Bryan Hopkins, John Gookin, Samantha Thompson

Human–Wildlife Interactions

Although bear-inflicted (Ursus spp.) human fatalities are rare in North America, human injuries, property damage, and bear mortalities occur wherever bears and humans commingle. We investigated the efficacy of portable electric fencing systems for bear deterrence under a variety of environmental conditions in the lab and field. Our results showed that the bear deterrent systems we evaluated were effective in protecting humans, their food, and property from bears >99% of the time. Herein, we discuss the benefits of using electric fencing, reasons why fences sometimes fail, and provide guidance regarding the most effective implementation of the systems we evaluated. …

Managing Human-Habituated Bears To Enhance Survival, Habitat Effectiveness, And Public Viewing, Kerry A. Gunther, Katharine R. Wilmot, Steven L. Cain, Travis C. Wyman, Eric G. Reinertson, Amanda M. Bramblett

Human–Wildlife Interactions

The negative impacts on bears (Ursus spp.) from human activities associated with roads and developments are well documented. These impacts include displacement of bears from high-quality foods and habitats, diminished habitat effectiveness, and reduced survival rates. Additionally, increased public visitations to national parks accompanied with benign encounters with bears along park roads have caused more bears to habituate to the presence of people. In some contexts, habituation can predispose bears to being exposed to and rewarded by anthropogenic foods, which can also lower survival rates. The managers and staff of Yellowstone National Park located in Wyoming, Montana, and Idaho, …

Species Composition And Temporal Patterns Of Wildlife-Vehicle Collisions In Southwest Virginia, Usa, James A. Vance, Walter H. Smith, Gabrielle L. Smith

Human–Wildlife Interactions

Mitigating wildlife–vehicle collisions (WVCs) is becoming a major wildlife conservation focus, particularly in areas characterized by increased anthropogenic development. Concomitantly, wildlife managers and transportation planners need better information regarding spatiotemporal patterns of WVCs to develop measures that mitigate negative impacts on wildlife. To address this need, in 2015 we conducted a yearlong WVC study in the Appalachian Mountains of Virginia, USA to determine the species composition of WVCs across mammals, birds, and herpetofauna. In addition, we compared patterns of WVC road mortalities across 2 adjacent routes with different vehicle traffic volumes and evaluated the relationships between temporal variations in WVC …

Using Global Positioning System Technology To Manage Human-Black Bear Incidents At Yosemite National Park, Rachel L. Mazur, Ryan M. Leahy, Caitlin J. Lee-Roney, Kathleen E. Patrick

Human–Wildlife Interactions

Managing human–bear (Ursus spp.) incidents is a top management priority in national parks inhabited by bears. Yosemite National Park (Yosemite), located in the Sierra Nevada in California, USA, receives up to 5 million visitors annually. It is also home to 300–500 black bears (U. americanus). Yosemite has an extensive history of black bear research, educational programs, and innovative solutions for reducing human–bear incidents. Despite this, human–bear incidents peaked in 1998 at 1,584. The resulting political fallout led to Yosemite receiving funds to expand its bear management program, including increasing its staffing and garbage pick-up, and improving the …

Black Bears Recolonizing Historic Ranges: Indiana Human–Bear Interactions, Bradford J. Westrich, Emily B. Mccallen, Geriann Albers

Human–Wildlife Interactions

Over a century after extirpation from Indiana, USA, 2 American black bears (Ursus americanus) were confirmed in the state during the summers of 2015 and 2016. The first bear encountered a public and management agency unaccustomed to living with large carnivores, which resulted in intentional and unintentional feedings, habituation, and ultimately its euthanasia. The Indiana Department of Natural Resources (DNR) attempted to learn from this encounter and began preparing for the next transient black bear. Education materials were created to help minimize human–bear interactions, promote living safely with bears, and inform about what to do when encountering a …

A Call For Proactive Human–Bear Conflict Mitigation, Annabella R. Helman

The Effect Of Religious Dress On Perceived Attractiveness And Trustworthiness, Courtney Swank

College of Graduate Studies: Theses & Dissertations

The hijab, a symbol of modesty and privacy in the Islamic faith, negatively affects ratings of perceived attractiveness. Although postcolonial feminism strives to portray women as not one universal group, but as an incorporation of different races, ethnicities, social classes, and other cultures, the Western world may not be where it endeavors to be. In this study the impact of the hijab on people’s perceptions of attractiveness was examined. Participants rated four target photos of the same woman with and without a hijab, and with or without cosmetics. Attractiveness and trustworthiness was then assessed in each condition, between genders, in …

Mchm (4-Methylcyclohexane Methanol) Influences The Predator-Prey Interaction Between Danio Rerio And Daphnia Magna, Anna C. Wagner

College of Graduate Studies: Theses & Dissertations

Chemical contamination alters organism-level traits, such as activity and feeding, that can ultimately affect aquatic trophic interactions. Despite the importance of predator-prey relationships in aquatic communities, chemical toxicity is often tested on single species prior to use. For example, 4-methylcyclohexane methanol (MCHM) used in industrial coal-cleaning enters the environment regularly from low-level contamination during disposal and occasionally in high concentrations following accidental spills, but its effects on fish-zooplankton interactions remain unknown. It was hypothesized MCHM exposure affects zebrafish and D. magna swimming behavior differently when exposed individually or together, and ultimately affects their relationship. Zebrafish and D. magna were exposed …

Finally, it discusses how to improve U.S. businesses’ compliance with existing antidiscrimination law.

How Long Is History's Shadow?, Anita S. Krishnakumar

Faculty Publications

In Congress’s Constitution, Josh Chafetz takes issue with those who have questioned the value of Congress in recent years. He argues that Congress’s critics focus too heavily on its legislative function and ignore several important nonlegislative powers that enable Congress to exert significant authority vis-à-vis the other branches. Chafetz engages in close historical examination of these nonlegislative powers and notes that in some cases, Congress has ceased exercising them as robustly as it once did, while in others it has unwittingly ceded them to another branch. Congress’s Constitution urges Congress to reassert several of its ceded powers more aggressively …

Corporate Social Responsibility And Crowdwashing In The Gig Economy, Miriam A. Cherry

Faculty Publications

(Excerpt)

Within this Article, I elaborate on the term “crowdwashing,” a neologism. Even though many online platforms describe themselves as “communities” that are part of the “sharing economy,” this “sharing” terminology is largely a misnomer when describing the activities of larger commercialized on-demand platforms. Rather than referring to volunteer efforts for collective benefit, many references to “sharing” in the “sharing economy” refer to the concept of commodification of previously underutilized assets. For example, consider receiving money for the rental of a spare bedroom through AirBnB or the sale of small, previously unproductive periods of time to complete tasks on Amazon’s …

The Death Of Appraisal Arbitrage: Ending Windfalls For Deal Dissenters, William J. Carney, Keith Sharfman

Faculty Publications

In this article, we take note of a new and positive development in Delaware's law of appraisal: more robust enforcement of Section 262(h), which expressly excludes from fair value in appraisal litigation the value that is uniquely associated with the deal from which the shareholders seeking appraisal are dissenting. For public firms, this implies that deal dissenters are entitled to no more than the price that prevailed prior to the deal's announcement.

In a salutary development, the Delaware Chancery Court took this approach in its recent appraisal decision in Verition Master Fund Partners, Ltd. v. Aruba Networks, Inc., awarding …

Textualism And Statutory Precedents, Anita S. Krishnakumar

Faculty Publications

This Article seeks to shed light on a little-noticed trend in recent U.S. Supreme Court statutory interpretation cases: The Court’s textualist Justices—or at least some subset of them—have proved remarkably willing to abandon stare decisis and to argue in favor of overruling established statutory interpretation precedents. This is especially curious given that statutory precedents are supposed to be sacrosanct; Congress, rather than the Court, is the preferred vehicle for correcting any errors in the judicial construction of a statute and courts are to overrule such constructions only in rare, compelling circumstances. What, then, accounts for the textualist Justices’ brazen willingness …

Matsushita At Thirty: Has The Pendulum Swung Too Far In Favor Of Summary Judgment?, Edward D. Cavanagh

Faculty Publications

(Excerpt)

The Supreme Court's ruling in Matsushita Electric Industrial Co. v. Zenith Radio Corp. marked the end of judicial hostility to Rule 56 motions and effectively legitimized the use of summary judgment in antitrust cases. The 5-4 decision dramatically altered the antitrust litigation landscape both procedurally and substantively. Procedurally, the decision underscored the trans-substantive nature of summary judgment, making clear that summary judgment is as appropriate in complex antitrust cases as in any other area of the law. Matsushita also made clear that the legal standards for summary judgment mirror the legal standards for directed verdict at trial. In …

Faith-Based Emergency Powers, Noa Ben-Asher

Faculty Publications

This Article explores an expanding phenomenon that it calls Faith-Based Emergency Powers. In the twenty-first century, conservatives have come to rely heavily on Faith-Based Emergency Powers as a leading legal strategy in the Culture Wars. This strategy involves carving faith-based exceptions to rights of women and LGBT people. The concept of Faith-Based Emergency Powers is developed in this Article through an analogy to the “War on Terror.” In the War on Terror, conservatives typically have taken the position that judges, legislators, and the public must defer to the President and the executive branch in matters involving national security. This argument …

Student Protests And Academic Freedom In An Age Of #Blacklivesmatter, Philip Lee

Faculty Publications

(Excerpt)

Student activism has been part of the fabric of American higher education since the eighteenth century. Indeed, some scholars have called it "as American as apple pie." From Harvard's "Great Butter Rebellion" in 1766 when students pushed for better food to the multicultural movement of today when students have demanded increased diversity in student, staff, faculty, and curriculum, students have long pressed to have their voices heard. Continuing in this tradition, we now live in an age of student activists who, by organizing through social media, are getting more people involved in political conversations and causes than would otherwise …

Trapped: Cycles Of Violence And Discrimination Against Lesbian, Gay, Bisexual, And Transgender Persons In Guyana, Ashley Binetti Armstrong

Faculty Publications

(Excerpt)

Human rights fact-finding aims to uncover and describe human rights concerns to expose both the abuses themselves and the factors that enable their perpetuation. Giving voice to survivors and victims is central to the fact-finding methodology: After all, “. . . if one really wishes to know how justice is administered in a country . . . [o]ne goes to the unprotected – those, precisely, who need the law’s protection most – and listens to their testimony.”

Through Georgetown Law’s Fact-Finding Practicum, the Human Rights Institute works with a small group of students on a cutting-edge human rights …

#Socialjustice: Combatting Implicit Bias In An Age Of Millennials, Colorblindness, & Microaggressions, Renee Nicole Allen, Deshun Harris

Faculty Publications

Law schools, in an effort to produce practice-ready graduates, are in an opportune position to take the lead in confronting social justice. Many schools are shifting from traditional classroom instruction to more experiential learning environments which place students early in their academic pursuits in contact with clients and legal problems. While academic support originally focused on racial integration in law schools, today’s Academic Support professionals support students who are diverse in various ways. As professionals, we cannot assume that our diverse students do not carry bias. Implicit bias, a bias one is not consciously aware of, has the ability to …

The Role Of Data Analysis Software In Graduate Programs In Education And Post-Graduate Research, Michael Harwell

Mid-Western Educational Researcher

The importance of data analysis software in graduate programs in education and post-graduate educational research is self-evident. However the role of this software in facilitating supererogated statistical practice versus "cookbookery" is unclear. The need to rigorously document the role of data analysis software in students' graduate coursework and research, and in post-graduate educational research studies, is emphasized along with recommendations for obtaining this information.

Molecular And In Silico Cloning, Identification, And Preharvest Period Expression Analysis Of A Putative Cytochrome P450 Monooxygenase Gene From Camellia Sinensis (L.) Kuntze (Tea), Ayşenur Emi̇noğlu, Yeşi̇m Aktürk Di̇zman, Şule Güzel, Ali̇ Osman Beldüz

Turkish Journal of Biology

Cytochrome P450 monooxygenases are one of the largest heme-containing protein groups, and the majority of them catalyze hydroxylation reactions dependent on nicotinamide adenine dinucleotide phosphate and oxygen. Cytochrome P450 (CYP) enzymes function in a wide range of monooxygenation reactions essential in primary and secondary metabolism in plants. Camellia sinensis (L.) Kuntze is a commercially and economically valuable plant due to its medicinally important secondary metabolites and as a beloved beverage. Cytochrome P450 monooxygenases play a significant role in the biosynthesis of a variety of secondary metabolites in tea. Although the biosynthesis of secondary metabolites has been investigated in detail, there …

Overexpression Of The Alfalfa Dnaj-Like Protein (Msdjlp) Gene Enhancestolerance To Chilling And Heat Stresses In Transgenic Tobacco Plants, Ki-Won Lee, Md. Atikur Rahman, Ki-Yong Kim, Gi Jun Choi, Joon-Yung Cha, Mi Sun Cheong, Abdullah Mohammad Shohael, Chris Jones, Sang Hoon Lee

Turkish Journal of Biology

n plant development and abiotic stress response processes. In this study, we examined the role of a HSP, the Medicago sativa DnaJ-like protein (MsDJLP), in alfalfa and its potential application for the development of abiotic stress tolerance in plants. We found that expression of the MsDJLP gene was induced by chilling (4 °C) and heat (42 °C), but not by cadmium (500 µM) or arsenic (500 µM) stresses. We then cloned the MsDJLP gene downstream of the strong constitutive CaMV 35S promoter and transformed it into tobacco plants. Ectopic expression of MsDJLP conferred enhanced tolerance to both chilling and heat …
