Plastic pollution in the ocean is a global concern with more than 8 million tons of plastic dumped into our oceans every year. This policy paper assesses plastic pollution in Narragansett Bay and the negative implications it holds on local seabird populations. Also, essential background information on plastic production and throwaway culture is provided. Moreover, the biological significance of seabirds is described, highlighting the vital role such populations play in local ecosystems such as Narragansett Bay. This paper contributes research to the global issue of plastic pollution by observing declining native wildlife life populations, such as seabirds, on a local …

Cumulative Adverse Effects Of Offshore Wind Energy Development On Wildlife, Morgan Goodale

Doctoral Dissertations

Offshore wind energy development is being pursued as a critical component in achieving a low-carbon energy economy. While the adverse effects of one wind farm on a particular wildlife population may be negligible, the aggregate effect of multiple wind farms through space and time could cause wildlife population declines. The risk of cumulative adverse effects (CAE) of offshore wind farms on wildlife is poorly researched and assessment processes are underdeveloped. Assessments of CAE must first calculate the cumulative exposure of a wildlife population to a hazard and then estimate how the exposure will affect the population. Our research responds to …

Delineating Metrics Of Diversity For A Snake Community In A Rare Ecosystem, Zachary John Marcou

Electronic Theses and Dissertations

Snakes are among the least understood vertebrate groups despite their considerable diversity. A diverse community of snakes in an ecosystem can indicate a complex habitat structure that is capable of supporting a robust assemblage of other biota. I used remote photography arrays (RPA) to quantify metrics of diversity for the snake community occurring in a ~7,000–ha tract of contiguous Longleaf Pine (Pinus palustris) Savanna within the Angelina National Forest (ANF; Angelina and Jasper Cos., TX), over the course of two consecutive snake activity seasons. I quantified the snake species richness, Shannon diversity, and Shannon equitability for the snake community in …

Analysis Of The White-Tailed Deer Population Of Hobbs State Park, Jesse Morrison

Biological and Agricultural Engineering Undergraduate Honors Theses

White Tailed deer (Odocoileus virginianus) are the only deer species native to Arkansas, playing a crucial role in the ecosystem. Healthy deer populations are important for environmental and human wellbeing, and overpopulation can lead to poor herd health, overgrazing, increased vehicle collisions, and transmission of diseases. Monitoring deer populations through surveys can be a useful tool in managing wildlife and maintaining Arkansas’ natural resources.

This study analyzed trends in Hobbs State Park’s deer population and estimated the current roadside deer population of the park. Data from past surveys was analyzed for trends using a Mann-Kendall Test, and a distance sampling …

Reducing The Risk Of Invasive Pathogens To Wildlife Health In The United States, Edward E. Clark Jr., Marshall Meyers, David Eldon Starling, Brent Stewart, Nathan Stone, Gary Tabor, Jeffrey S. White

National Invasive Species Council

Call to Action

In keeping with action items 4.3.1 and 4.3.2 of the 2016–2018 National Invasive Species Council (NISC) Management Plan, the Wildlife Health Task Team of the Invasive Species Advisory Committee (ISAC) was charged with: 1) identifying the major areas of vulnerability to native wildlife from the introduction and spread of invasive pathogens, and 2) making recommendations to address these vulnerabilities, including through potential changes in statute, regulation, policy, or practice of the relevant agencies.

Wild Horses And Burros: An Overview, S. Nicole Frey, Eric Thacker

All Current Publications

The Federal government manages feral horses and burros under the Wild and Free-roaming Horse and Burro Act. This fact sheet discusses: what wild and feral horses and burros are, there status and populations in the U.S., the problems caused by over-abundance, how "extra" animals are managed, and future management considerations.

A Review Of Contemporary U.S. Wild Horse And Burro Management Policies Relative To Desired Management Outcomes, Keith A. Norris

Human–Wildlife Interactions

Legally defined “wild” horse (Equus ferus caballus ) and burro (E. asinus ; WHB) populations in the United States exceed established population objectives. The context of WHB policy and management can be categorized into ecological, geographical, legal, social, and political perspectives. Ecologically, all WHB populations in the United States are considered feral animals, but certain populations are afforded protection and management by the federal Wild Free-Roaming Horses and Burros Act (WFRHBA) of 1971. The current policy and management paradigms under which the WFRHBA is being implemented has contributed to rangeland degradation, poor WHB health, and impacts to native wildlife. This …

Efficacy Of Ontario Rabies Vaccine Baits (Onrab) Against Rabies Infection In Raccoons, Amy Gilbert, Shylo Johnson, Nikki Walker, Chad Wickham, Alex Beath, Kurt C. Vercauteren

USDA Wildlife Services: Staff Publications

In the US, rabies lyssavirus (RABV) only circulates in wildlife species and the most significant reservoir from a public and animal health perspective is the raccoon (Procyon lotor). Management of wildlife rabies relies principally on oral rabies vaccination (ORV) strategies using vaccine-laden bait delivery to freeranging target hosts, in order to reduce the susceptible population to prevent the spread of and eliminate RABV circulation. Our objective was to evaluate efficacy of the Ontario Rabies Vaccine Bait (ONRAB) against a lethal RABV challenge in captive raccoons. Sham or live vaccine baits were offered to 50 raccoons and efficacy was …

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 …

Camera Traps In Wildlife Research: Through My Lens, Bryson P. Allen

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Wildlife species can be difficult to study because they can have very large ranges and can be wary of observers. Researchers have been using camera traps in recent decades as a way to study wildlife behavior and population metrics. Here I explore the history of these tools in wildlife biology, their possible applications, and limitations.

Evaluating Bighorn Sheep Herd Response After Selective Removal Of Mycoplasma Ovipneumoniae Chronic Shedders, Tyler J. Garwood

Electronic Theses and Dissertations

Infected individuals vary in their contribution to disease persistence, and chronically infected individuals may sustain disease in a population. One disease that might persist in a population through chronically infected individuals is pneumonia in wild sheep. Mycoplasma ovipneumoniae (Mo), a pathogen of Caprinae commonly present in domestic sheep and goats, strongly correlates with pneumonia epizootics when it infects wild sheep populations. These epizootics can cause 40-100% herd mortality in an initial all-age dieoff, precipitate annual lamb mortality as high as 100% in following years, and sustain adult mortality long after initial all-age dieoffs. We conducted an experiment in the Black …

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 …
