Investigating Reef Contact Rates Of Snorkel Visitors At Koh Sak, Pattaya On Guided And Non-Guided Coral Reef Tours, Wayne Phillips Jan 2018

Investigating Reef Contact Rates Of Snorkel Visitors At Koh Sak, Pattaya On Guided And Non-Guided Coral Reef Tours, Wayne Phillips

Applied Environmental Research

Recreational snorkelling is a popular activity at Koh Sak, Pattaya Bay and although most snorkel visitors to the island arrive by speedboat on guided tours, many visitors arrive on tours that do not provide a guide. Because there is widespread agreement that reef-based tourism negatively impacts coral reefs it is important to understand the potential role guides play in reducing visitor impacts. In this study 421 snorkelers (35 % of whom came on non-guided tours) were observed on the reef for a period of 10 minutes. The following information was recorded so that a per person reef-contact rate could be …

Multiple-Use Management Of Western U.S. Rangelands: Wild Horses, Wildlife, And Livestock, Rick E. Danvir Jan 2018

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 …

Wild Horse Demography: Implications For Sustainable Management Within Economic Constraints, Robert A. Garrott Jan 2018

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 …

Spatial Ecology Observations From Feral Horses Equipped With Global Positioning System Transmitters, Jacob D. Hennig, Jeffrey L. Beck, J. Derek Scasta Jan 2018

Spatial Ecology Observations From Feral Horses Equipped With Global Positioning System Transmitters, Jacob D. Hennig, Jeffrey L. Beck, J. Derek Scasta

Human–Wildlife Interactions

Our understanding of the spatial ecology of feral horses (Equus ferus caballus ) and burros (E . asinus ) in the United States is limited. Robust location data are needed to better understand the permeability of Bureau of Land Management Herd Management Area boundaries, relative to feral horse movement patterns and home ranges. To increase our understanding of feral horse movement, in February to March 2017, we deployed global positioning system (GPS) collars on 14 females ≥5 years old that were captured in the Adobe Town Herd Management Area (ATHMA) of southcentral Wyoming, USA. Herein, we report initial results from …

Twenty Years Of Spayvac® Research: Potential Implications For Regulating Feral Horse And Burro Populations In The United States, Ursula S. Bechert, Mark A. Fraker Jan 2018

Twenty Years Of Spayvac® Research: Potential Implications For Regulating Feral Horse And Burro Populations In The United States, Ursula S. Bechert, Mark A. Fraker

Human–Wildlife Interactions

There are currently >75,000 feral horses (Equus ferus caballus) and burros (E. asinus ) on U.S. public lands, yet the Appropriate Management Level (AML) is set at just under 27,000. Wildlife managers, conservation biologists, and livestock ranchers are concerned about the impacts that these free-ranging horses have on shared rangelands. Immunocontraceptive vaccines may have the greatest potential to regulate horse population numbers once AML is reached; however, the vaccine must have multi-year efficacy to be both technically feasible and cost-effective. Immunocontraception based on porcine zona pellucida (PZP)-specific antigens is highly tissue-specific, targeting the ova, and blocking sperm binding through antibody …

Consequences Of Porcine Zona Pellucida Immunocontraception To Feral Horses, Cassandra M.V. Nuñez Jan 2018

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

Physiological Responses In Reindeer To The Application Of A Conducted Electrical Weapon, Camilla L. Lieske, Kimberlee B. Beckmen, Larry L. Lewis Jan 2018

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, …

Fencing Alleviates Nuisance Molting Goose Problems In An Urban Park In Tennessee, Jonathan T. Mills, Daniel L. Combs Jan 2018

Fencing Alleviates Nuisance Molting Goose Problems In An Urban Park In Tennessee, Jonathan T. Mills, Daniel L. Combs

Human–Wildlife Interactions

Canada geese (Branta canadensis; geese) often congregate in high public use areas while molting during summer, resulting in increased nuisance complaints. We censused geese that inhabited a Cookeville city park in Tennessee, USA on a weekly basis from 2013-2014 to determine the magnitude, trends, and seasonal nature of problems caused by urban goose flocks. Fewer than 50 geese were counted in most months except during the molt, when numbers increased to over 200. Most geese dispersed from the park shortly after completion of the molt. Molt site fidelity to the park was estimated to be 51.5%, indicating that permanent …

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 Jan 2018

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 …

Canid Vs. Canid: Insights Into Coyote-Dog Encounters From Social Media, Erin E. Boydston, Eric S. Abelson, Ari Kazanjian, Daniel T. Blumstein Jan 2018

Canid Vs. Canid: Insights Into Coyote-Dog Encounters From Social Media, Erin E. Boydston, Eric S. Abelson, Ari Kazanjian, Daniel T. Blumstein

Human–Wildlife Interactions

While the relationship between coyotes (Canis latrans) and house cats (Felis catus) may be characterized as one between predators and their prey, coyote interactions with domestic dogs (C. lupus familiaris) appear to be more varied and may include behaviors associated with canid sociality. While encounters between coyotes and dogs are difficult to observe, we capitalized on publically available video recordings of coyote-dog encounters to observe canid behaviors and examined 35 video clips downloaded from YouTube during fall 2014. We identified coyote-dog interactions that were playful, agonistic, or predatory; those that we could not clearly …

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne Jan 2018

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne

Human–Wildlife Interactions

The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities nor …

Experimental Tests Of Nonsurgical Reproductive Inhibitors To Prevent Coyote Reproduction, Julie K. Young, Marjorie J. Macgregor, Eric M. Gese, Douglas C. Eckery Jan 2018

Experimental Tests Of Nonsurgical Reproductive Inhibitors To Prevent Coyote Reproduction, Julie K. Young, Marjorie J. Macgregor, Eric M. Gese, Douglas C. Eckery

Human–Wildlife Interactions

Sterilization is an effective nonlethal tool to reduce livestock depredation by coyotes (Canis latrans) because adults without pups to provision are less likely to kill livestock. Surgical sterilization is costly and invasive, so identifying non-surgical methods for canids that allows wide-scale application is important. We conducted a preliminary assessment of two types of reproductive inhibitors (gonadotropin releasing hormone (GnRH) vaccine and deslorelin, a GnRH agonist, on coyote reproductive capabilities. We treated captive coyotes with a GnRH vaccine (n = 6 males, n = 6 females) or deslorelin (n = 6 males), measured number of litters and pups born, …

Strike Hazard Posed By Columbids To Military Aircraft, Melanie R. Colón, Ashley M. Long Jan 2018

Strike Hazard Posed By Columbids To Military Aircraft, Melanie R. Colón, Ashley M. Long

Human–Wildlife Interactions

Wildlife-aircraft strikes threaten both human and animal safety and result in hundreds of millions of dollars per year in aircraft damage and lost flight hours. Large-bodied birds are especially hazardous to aircraft. However, given high-speed flight at low altitudes, military aircraft may be especially vulnerable to strikes and more susceptible to damage even when encountering small birds. We summarized all wildlife-aircraft strike records from Randolph Air Force Base (San Antonio, Texas) over a 25-year period and compared the number and cost of strikes across avian species and species groups. Because columbids (i.e., pigeons and doves) are among the most frequently …

Post-Release Activity And Habitat Selection Of Rehabilitated Black Bears, Patrick J. Myers, Julie K. Young Jan 2018

Post-Release Activity And Habitat Selection Of Rehabilitated Black Bears, Patrick J. Myers, Julie K. Young

Human–Wildlife Interactions

Despite the long history of wildlife rehabilitation and the abundance of empirical knowledge of the behavior and resource selection of wildlife species, rarely does research bridge these disciplines. Such investigations could be of value to wildlife managers and rehabilitators by revealing the suitability of the habitat at selected release sites, the wild activities, behavior, and fitness of the captive-reared individuals, and ultimately the efficacy of the rehabilitation process. Rehabilitated carnivores warrant specific attention, given that they are wide-ranging and may behave in ways that threaten human safety or interests. We investigated the behavior of orphan, rehabilitated black bear cubs ( …

Can The Vaquita Be Saved From Extinction?, Gerardo Rodríguez-Quiroz, Wenceslao Valenzuela-Quiñonez, Héctor A. González-Ocampo, Alfredo Ortega-Rubio

Human–Wildlife Interactions

The vaquita (Phocoena sinus) is considered the world’s most endangered marine mammal. It is the smallest member of the porpoise family endemic to the upper part of the Gulf of California. The current population is estimated at less than 30 individuals. The primary reasons for the species decline includes limited habitat and incidental mortalities associated with illegal gillnet fishing activities. Since 2008, the Mexican government has taken environmental and economic actions to protect the vaquita’s focusing in reducing by-catch deaths to zero. In 2015, a federal Agreement decreed by the Secretaría de Agricultura, Ganadería, Desarrollo Rural, Pesca y …

Conservation Of Threatened Canada-Usa Trans-Border Grizzly Bears Linked To Comprehensive Conflict Reduction, Michael F. Proctor, Wayne F. Kasworm, Kimberly M. Annis, A. Grant Machutchon, Justin E. Teisberg, Thomas G. Radandt, Chris Servheen

Human–Wildlife Interactions

Mortality resulting from human–wildlife conflicts affects wildlife populations globally. Since 2004, we have been researching conservation issues and implementing a comprehensive program to reduce human–bear conflicts (Ursus spp.; HBC) for 3 small, fragmented, and threatened grizzly bear (U. arctos) populations in the trans-border region of southwest Canada and northwest USA. We explored the temporal and spatial patterns of conflict mortality and found that HBC contributed significantly to the threatened status of these populations by causing decline, fragmentation, and decreased habitat effectiveness. Our program to reduce HBCs primarily included strategic private lands purchased to reduce human density in …

Species Composition And Temporal Patterns Of Wildlife-Vehicle Collisions In Southwest Virginia, Usa, James A. Vance, Walter H. Smith, Gabrielle L. Smith Jan 2018

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 …

Sloth Bear Attacks On Humans In Central India: Implications For Species Conservation, Nisha Singh, Swapnil Sonone, Nishith Dharaiya Jan 2018

Sloth Bear Attacks On Humans In Central India: Implications For Species Conservation, Nisha Singh, Swapnil Sonone, Nishith Dharaiya

Human–Wildlife Interactions

Conflicts with wild animals are increasing as human populations grow and related anthropogenic activities encroach into wildlife habitats. A good example of this situation is the increase in conflicts between humans and sloth bears (Melursus ursinus) in India. Sloth bears are known for their aggressive and unpredictable behavior. More human fatalities and injuries have been attributed to sloth bear attacks than all recorded incidences of wildlife attacks in Buldhana Forest Division of Maharashtra, India. We interviewed 51 victims that were attacked by sloth bears between 2009-2017 to better understand the reasons for the attacks. Thirty-four of the attacks …

Lead Concentrations In White-Tailed Deer Tissue Due To Retained Bullets, Meghan C. Zimmer, Tod L. Osier Jan 2018

Lead Concentrations In White-Tailed Deer Tissue Due To Retained Bullets, Meghan C. Zimmer, Tod L. Osier

Human–Wildlife Interactions

Mobilization of lead from retained bullets may lead to elevated lead levels in game tissue with consequences for consumers. We investigated lead mobilization in 2 white-tailed deer (Odocoileus virginianus) carrying retained lead ammunition from previous gunshot wounds. Lead concentrations in muscle tissue of deer with retained lead bullets were in the same range as control deer. In contrast, 1 deer had higher bone lead levels than controls, suggesting mobilization occurred. Our results suggest that lead mobilization to meat from retained lead bullets does not appear to pose a consumption risk for those consuming meat that is physically distant from lead …

Motivations And Satisfaction Of North Dakota Deer Hunters During A Temporal Decline In Deer Populations, Kristen E. Black, William F. Jensen, Robert Newman, Jason R. Boulanger Jan 2018

Motivations And Satisfaction Of North Dakota Deer Hunters During A Temporal Decline In Deer Populations, Kristen E. Black, William F. Jensen, Robert Newman, Jason R. Boulanger

Human–Wildlife Interactions

Achieving state wildlife agency biological goals for deer (Odocoileus spp.) management may often conflict with hunter desires. Concomitantly, better information is needed to optimize agency deer herd management goals with hunters’ social goals. In 2016, we surveyed 3,000 North Dakota, USA, resident deer hunters using a self-administered mail survey to gain a better understanding of motivations, satisfaction, and hunter demographics that may be used to inform hunter recruitment and retention (HRR) efforts during a period of reduced statewide deer populations. With deer-gun license availability strictly limited, we explored the possibility that some gun hunters may have been engaging …

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 Jan 2018

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, …

Top Tens In 2017: Patent, Trademark, Copyright And Trade Secret Cases, Stephen M. Mcjohn

Suffolk University Law School Faculty Works

The Supreme Court loosened the grip of patentees on their products, holding that contractual restrictions on patented product are ineffective to preserve patent rights. The Court also loosened the grip of the Eastern District of Texas on patent cases, announcing a narrower standard that will send more cases to Delaware. The Federal Circuit cases piled up on applying the Alice standard to filter nonpatentable abstract ideas from patentable inventions. Meanwhile, even as the constitutionality of the Patent Trial and Appeals Board pends before the Supreme Court, hundreds of PTAB decisions on the validity of patents move onward to the Federal …

Excavating Race-Based Disadvantage Among Class-Privileged People Of Color, Khiara Bridges Jan 2018

Excavating Race-Based Disadvantage Among Class-Privileged People Of Color, Khiara Bridges

Faculty Scholarship

The aim of this article is to begin to theorize the fraught space within which class-privileged racial minorities exist — the disadvantage within their privilege. The article posits that the invisibility of the racial subordination of wealthier people of color (that is, their marginalization on account of their race) is fertile soil for the germination of post-racialism — the sense that we, as a nation, have overcome our racial problems. The dramatic visibility of the minority poor’s suffering, combined with the relative invisibility of the suffering of those minorities who are not poor, breeds the belief that class is now …
