The use of camera traps, small Sherman live traps, large live traps, and tracking methods were …

Initiation Of A Roundtable Meeting To Determine Safety Hazards And Provide Education To Range Bison Herd Workers, Lucia Finocchiaro

Capstone Experience: Master of Public Health

This capstone project serves as an important piece of greater project studying bison handling. Bison production is both a growing and dangerous industry. As a new enterprise in many parts of the country and on tribal lands, significant numbers of untrained employees may be hired. This project undertakes methods to better understand the risks associated with bison handling and to thereby improve handling procedures and increase safety. Herd managers (from tribal and non-tribal sites), researchers, safety experts, and stakeholders were brought together for a roundtable meeting in Omaha. This meeting was designed to provide stakeholders a forum to discuss common …

Animal Experimentation: Working Towards A Paradigm Change, Kathrin Herrmann (Ed.), Kimberley Jayne (Ed.)

eBooks

Animal experimentation has been one of the most controversial areas of animal use, mainly due to the intentional harms inflicted upon animals for the sake of hoped-for benefits in humans. Despite this rationale for continued animal experimentation, shortcomings of this practice have become increasingly more apparent and well-documented. However, these limitations are not yet widely known or appreciated, and there is a danger that they may simply be ignored. The 51 experts who have contributed to Animal Experimentation: Working Towards a Paradigm Change critically review current animal use in science, present new and innovative non-animal approaches to address urgent scientific …

Morphological And Color Variation In Poicephalus Parrots, Eileen Connon

Undergraduate Honors Thesis Projects

Though describing and delimiting species is one of the principle aspects of many disciplines within biology, there is often debate about which methods and concepts should be used to make such decisions. The Tobias criteria for quantitative species delimitation represent one attempt to create a standard method of delimiting species based on the morphological species concept. However, previous examples of using these criteria have not always been completely quantitative. This study uses quantitative morphological and color data of three Poicephalusparrots as a case study for the effectiveness of the Tobias criteria. The results show varying levels of support for …

Assessment Of Wildlife Rehabilitation Trends: Domestic Dog And Cat Attacks, Rachel Wilson

Undergraduate Honors Thesis Projects

Human-wildlife conflict is a growing concern, and domestic cat predation is estimated to be responsible for billions of wildlife deaths every year in the Unites States. Domestic dog predation has been less well studied, but as dogs are the second most numerous pet in the U.S. after cats, their impact on native wildlife should also be assessed. One method to assess domestic animal predation is to examine trends in wildlife rehabilitation records. Using the online database WILD-ONe, I analyzed over 31,000 wildlife hospital records in the United States from 2011-2016. During this time span, data showed over 14,000 domestic dog …

Crispr-Mediated Gene Editing: Scientific And Ethical Issues, Jarrod Bailey

Genetics Collection

There remains substantial evidence to warrant great concern over the poor efficiency and specificity of clustered regularly interspaced short palindromic repeats (CRISPR)-mediated genetic modification (GM), despite relatively minor improvements compared to other GM methods. These issues cause persistent, adverse, ethical, and scientific consequences for GM animals, which may never be sufficiently resolvable.

Salmonid Species Diversity Predicts Salmon Consumption By Terrestrial Wildlife, Christina N. Service, Andrew N. Bateman, Megan S. Adams, Kyle A. Artelle, Thomas E. Reimchen, Paul C. Paquet, Chris T. Darimont

Habitat and Trophic Ecology Collection

1. Resource waves—spatial variation in resource phenology that extends feeding opportunities for mobile consumers—can affect the behaviour and productivity of recipient populations. Interspecific diversity among Pacific salmon species (Oncorhynchus spp.) creates staggered spawning events across space and time, thereby prolonging availability to terrestrial wildlife.

2. We sought to understand how such variation might influence consumption by terrestrial predators compared with resource abundance and intra- and interspecific competition.

3. Using stable isotope analysis, we investigated how the proportion of salmon in the annual diet of male black bears (Ursus americanus; n = 405) varies with species diversity and density of spawning …

Farm Animal Cognition—Linking Behavior, Welfare And Ethics, Christian Nawroth, Jan Langbein, Marjorie Coulon, Vivian Gabor, Susan Oesterwind, Judith Benz-Schwarzburg, Eberhard Von Borell

Social Cognition Collection

Farm animal welfare is a major concern for society and food production. To more accurately evaluate animal farming in general and to avoid exposing farm animals to poor welfare situations, it is necessary to understand not only their behavioral but also their cognitive needs and capacities. Thus, general knowledge of how farm animals perceive and interact with their environment is of major importance for a range of stakeholders, from citizens to politicians to cognitive ethologists to philosophers. This review aims to outline the current state of farm animal cognition research and focuses on ungulate livestock species, such as cattle, horses, …

Starvation Resistance Is Associated With Developmentally Specified Changes In Sleep, Feeding And Metabolic Rate, Elizabeth B. Brown, Melissa E. Slocumb, Milan Szuperak, Arianna Kerbs, Allen G. Gibbs, Matthew S. Kayser, Alex C. Keene

Life Sciences Faculty Research

Food shortage represents a primary challenge to survival, and animals have adapted diverse developmental, physiological and behavioral strategies to survive when food becomes unavailable. Starvation resistance is strongly influenced by ecological and evolutionary history, yet the genetic basis for the evolution of starvation resistance remains poorly understood. The fruit fly Drosophila melanogaster provides a powerful model for leveraging experimental evolution to investigate traits associated with starvation resistance. While control populations only live a few days without food, selection for starvation resistance results in populations that can survive weeks. We have previously shown that selection for starvation resistance results in increased …

Analyzing Chlorophyll-a (Chl-a) from Moderate Resolution Imaging Spectroradiomerer (MODIS) data after Penglai oil spills on 4 June 2011, found a bloom with peak value of Chl-a (13.66 mg m⁻³) spread over an area of 800 km² during 18–25 June 2011, and a pronounced increase in the monthly Chl-a concentration (6.40 mg m⁻³) on June 2012 in the Bohai Sea. Out of the 21 oil spills, 14 blooms were observed, while 11 …

Perceptual Lateralization Of Vocal Stimuli In Goats, Luigi Baciadonna, Christian Nawroth, Elodie F. Briefer, Alan G. Mcelligott

Communication Skills Collection

Functional asymmetries, for example, the preferential involvement of 1 brain hemisphere to process stimuli, may increase brain efficiency and the capacity to carry out tasks simultaneously. We investigated which hemisphere was primarily involved in processing acoustic stimuli in goats using a head-orienting paradigm. Three playbacks using goat vocalizations recorded in different contexts: food anticipation (positive), isolation (negative), food frustration (negative), as well as 1 playback involving dog barks (negative) were presented on the left and right sides of the test subjects simultaneously. The head-orienting response (left or right) and latency to resume feeding were recorded. The direction of the head-orienting …

Behavioral Flexibility Of A Generalist Carnivore, Sarah E. Daniels, Rachel E. Fanelli, Amy Gilbert, Sarah Sarah Benson‑Amram

United States Department of Agriculture Wildlife Services: Staff Publications

Innovative problem solving, repeated innovation, learning, and inhibitory control are cognitive abilities commonly regarded as important components of behaviorally flexible species. Animals exhibiting these cognitive abilities may be more likely to adapt to the unique demands of living in novel and rapidly changing environments, such as urbanized landscapes. Raccoons

(Procyon lotor) are an abundant, generalist species frequently found in urban habitats, and are capable of innovative problem solving, which makes them an ideal species to assess their behavioral flexibility. We gave 20 captive raccoons a multi-access puzzle box to investigate which behavioral and cognitive mechanisms enable the generation …

A Global Reassessment Of Solitary-Sociable Dolphins, Laetitia Nunny, Mark P. Simmonds

Personality Collection

Dolphins are typically regarded as highly social animals. However, some individuals live apart from their own species and may come to socialize with people through a recognized series of stages which are presented and expanded on in this paper. The term “solitary-sociable dolphins” has been used to describe these animals and such individuals have been identified from several different species and reported in many parts of the world. In many instances, the interactions with people that may follow their original isolation, and which typically become more intense over time, have created situations where the welfare of the animal has been …

Elevated Sensitivity To Tactile Stimuli In Stereotypic Horses, Sabrina Briefer Freymond, Déborah Bardou, Sandrine Beuret, Iris Bachmann, Klaus Zuberbühler, Elodie Briefer

Personality Collection

Although stereotypic behaviors are a common problem in captive animals, why certain individuals are more prone to develop them remains elusive. In horses, individuals show considerable differences in how they perceive and react to external events, suggesting that this may partially account for the emergence of stereotypies in this species. In this study, we focused on crib-biting, the most common stereotypy displayed by horses. We compared how established crib-biters (“CB” = 19) and normal controls (“C” = 18) differed in response to a standard “personality” assessment test battery, i.e., reactivity to humans, tactile sensitivity, social reactivity, locomotor activity, and curiosity …

Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines

Lewis Honors College Capstone Collection

Carotenoids serve various ecological roles in animals including coloration, immune responses, and vision. Carotenoid-derived coloration is greatly emphasized in the literature, particularly relating to mate choice and aposematic warning. However, the trade-offs between the color and non-color functions of carotenoids are not thoroughly explored. In the redheaded pine sawfly (Neodiprion lecontei), some larval populations have yellow pigmentation, using carotenoids derived from their diets for aposematic warning coloration. Other larval populations are white in color, having genetically lost the ability to produce the yellow pigment. Because carotenoids are essential to life functions in both the yellow and white populations, we aim …

Predicting Black Bear Activity At Backcountry Campsites In Bryce Canyon National Park, Utah, Wesley G. Larson, Tom Smith

Human–Wildlife Interactions

Developing the capacity to predict black bear (Ursus americanus; bear) activity in a diversity of habitats will help conserve bear populations and their habitats and minimize human–bear conflicts. This capacity will be particularly important in areas that provide bear habitat and offer backcountry hiking and camping experiences. Bryce Canyon National Park (BRCA), located on the edge of the Paunsaugunt Plateau in southern Utah, USA, provides important bear habitat and offers visitors 12 backcountry campsites. To effectively manage these areas to minimize human–bear conflicts, park managers will need better information about black bear use of these campsites and other …

Tree Squirrels And Fishers In Northern California: The Effects Of Masting Hardwoods On Stand Use, Andria M. Townsend

Cal Poly Humboldt theses and projects

In western North America, tree squirrels such as western gray (Sciurus griseus) and Douglas squirrels (Tamiasciurus douglasii) are potentially important prey for fishers (Pekania pennanti). Western gray squirrels in particular may be highly ranked due to their large body size. Masting trees including black oak (Quercus kelloggii) and tanoak (Notholithocarpus densiflorus) produce an important food source for tree squirrels; therefore, forest stands containing these trees may be useful to foraging fishers. I hypothesized that; 1) the abundance of western gray and Douglas squirrels in a stand is influenced by the …

A Survey On Horse Use And Management In Horse Clubs In China: A Pilot Study, Zhen Li, Zhen Li

Murray State Theses and Dissertations

During the past three decades, significant development of the Chinese equine industry has resulted in a rapid increase in the number of horses in the country. At the same time, many horse clubs face shortages of trained management personnel or specialists in equine science and technology. The objective of this survey was to document and evaluate horse management and use in Chinese horse clubs. A 29-question survey was developed using SurveyMonkey© and tested on a small pilot group before being revised and released to a general pool of participants. The questionnaire link was distributed through WeChat to specific personnel in …

Canis Lupus (Gray Wolf) Pup Survival In Yellowstone National Park, Anne Marie Jehle

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The aim of this study was to describe gray wolf (Canis lupus) pup survival rates throughout the summer months in Yellowstone National Park. Understanding pup survival has implications for trends in pack and population age structure, cooperative breeding ecology and other breeding tendencies, social hierarchies, and population fitness, among other elements of species-specific population ecology. A general understanding of trends in pup survival is also relevant to state and federal land that allow gray wolf harvest. Understanding such trends and survival ecology gives managers and biologists the opportunity to evaluate gray wolf populations at a more comprehensive level and implement …

Effects Of Energy Development On Movements, Home Ranges, And Resource Selection Of White-Tailed Deer In The Western Dakotas, Bailey S. Gullikson

Electronic Theses and Dissertations

Oil and natural gas development has increased in recent years and research is needed to assess potential impacts on white-tailed deer (Odocoileus virginianus) populations. Our objectives were to document movements, home ranges, and resource selection of female white-tailed deer in response to energy development in the western Dakotas. Our study areas included Dunn County, North Dakota, an area with current oil and gas development, and Grant County, North Dakota, and Perkins County, South Dakota, areas without current oil and gas development. We captured and fitted 150 female deer with Very High Frequency (VHF) collars across study sites, and …

A Review Of Equine Laminitis: Risk Factors And Predispositions, Molly C. Henion

Honors Theses and Capstones

Equine laminitis is a disease of the hoof characterized by inflammation or disruption of the sensitive and insensitive laminae located within the hoof. These structures are responsible for maintaining a secure connection between the third phalanx (P3) and the hoof wall. Damage to these laminae can weaken the attachment between the hoof wall and P3, causing separation and eventual rotation of P3. Equine laminitis can result from multiple triggers, but the most commonly seen cases of the disease are those which are related to endocrinopathy and metabolic related issues. This review will focus on determining the metabolic risk factors associated …

California Livestock Owners: An Assessment Of Familiarity With New Antimicrobial Rules And Access To Educational Outreach, Philip Theodor Paulson

Master's Theses

The purpose of this research is to support the California Department of Food & Agriculture (CDFA) with education and outreach about recent changes regarding antimicrobial use in livestock, and to enhance their emergency communications network. This was done by characterizing a population of small-scale livestock owners underserved with regards to educational outreach about animal health issues, such as antimicrobial use rules. The project also seeks to enhance public understanding of the importance of responsible antimicrobial use in animal and human health.

To accomplish this, the study used a survey administered in person at local farm supply stores and online to …

Western Australian Feral Pig Strategy 2020-2025, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

Management of invasive species is an important component of biosecurity. For species already established in Western Australia (WA), including feral pigs, effective management aims to reduce the impacts of those populations and detect occurrences of new populations, thereby preventing further harm to the State’s agriculture and biodiversity. Effective management also includes monitoring the density and distribution of established populations to define their boundaries and determine the effectiveness of control programs.

The foundations for a national biosecurity framework were established in 2007, with the development of the inaugural Australian Pest Animal Strategy (APAS). The Feral Pig Strategy (this Strategy) outlines the …

The Challenges For A Closed-To-The-Public Animal Sanctuary: Prioritizing Animal Welfare While Engaging In Educational Community Outreach, Lisa Tweed

All Master's Theses

Chimpanzee Sanctuary Northwest is a small primate sanctuary in Cle Elum, Washington, and is presently home to seven chimpanzees who were retired from biomedical research. I used this sanctuary as a case study to find out how a closed-to-the-public sanctuary can engage in educational outreach without compromising the welfare of the residents. I employed a combination of semi-structured interviews of sanctuary personnel, ethnographic participant-observation as a volunteer caregiver, and an online survey offered to the local community to help me understand the goals and limitations of sanctuaries. I also designed and conducted two educational programs for local area schools as …

A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead

Antioch University Dissertations & Theses

Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive …
