Does Cortisol Respond To A Social Perturbation In Captive Bonobos?, Tiffany Ly

Symposium of Student Scholars

All animals are influenced by their environment. For social species, this means that changes in group size or composition can have long-lasting effects on survival or reproduction. When these social species are placed in captivity and new individuals are introduced suddenly by zookeepers or researchers, these events can lead to stress by changing established dominance hierarchies. For example, these interactions can cause stress hormones—like cortisol in primates and humans—to be released in response to meeting unfamiliar individuals. We took advantage of an introduction event happening at a captive research and conservation facility to better understand how introducing a ...

Implications Of Visual Social Access On The Welfare And Behavior Of Shelter Dogs, Christina M. Walthers, Madison J. Pattillo, Jessie A. Catchpole, Lauren E. Faulkner, Lauren N. Mitchell, Allison L. Martin

Symposium of Student Scholars

Animal shelter environments have many stressful factors that impact the welfare of shelter dogs, such as lack of predictability and control, and social isolation. Social isolation has been found to increase abnormal behavior and lead to poorer adoption outcomes. Providing visual access to shelter dogs is a relatively easy environmental modification that increases social opportunities and allows for more predictability and control over the environment, potentially improving welfare. To investigate the impact of visual access on the behavior of dogs, we used a within-subject design, conducting 5-min focal observations four times weekly before, during, and after visual access was provided ...

Effects Of Essential Oils On Shelter Dog Behavior, Madison Pattillo

Symposium of Student Scholars

Shelter environments are stressful for dogs due to loud noises and unfamiliar surroundings. Dogs rely heavily on scent information, and exposure to some scents has shown reductions in activity and vocalizations in shelter dogs. We investigated the effects of two calming (lavender and vetiver) and two stimulating (lemon and rosemary) essential oils on crate position and active, resting, and stress behaviors. Observations were conducted for 5-min intervals eight times per week, with observations split between baseline and scent exposure. Our preliminary analysis using the Wilcoxon Signed-Rank test found that dogs exposed to lavender (n = 13), lemon (n = 9), rosemary (n ...

Wild Boar In Flanders, Belgium: (Dis)Agreements Between Key Stakeholders On Wild Boar Management Objectives, Actions, And Legal Provisions, Caroline Geeraerts, Anneleen Rutten, Emma Cartuyvels, Pieter Verschelde, Sander Devisscher, Francis Turkelboom, Paul Quataert, Jim Casaer

Human–Wildlife Interactions

Wild boar (Sus scrofa) reappeared in Flanders, Belgium in 2006 after more than half a century of absence. Besides being a native and highly valued game species in Europe, wild boar are also known to be responsible for car collisions, crop damage, disease transmission, and ecological damage at high densities. The management of wild boar therefore seeks to balance these positive and negative impacts. Given the highly fragmented landscape in Flanders and its multifunctional use, coexistence with wild boar is only possible through integrated management involving relevant stakeholder groups. However, to be successful, this requires that the management objectives, the ...

Assessing Metacognition In Rats, Abagail Hennessy

Undergraduate Student Research Internships Conference

Metacognition in humans refers to the ability to reflect upon one’s own state of knowledge, and to be able to make inferences based on that knowledge. Evidence of metacognition has been most often found in nonhuman primates. However, there may be evidence suggesting metacognitive skills in nonprimate animals as well, such as rats. The present study investigated whether Long Evans rats will utilize information they have about two 8 arm radial mazes to efficiently locate a food reward.

Cats And Wildlife: An Animal Welfare Perspective., John Hadidian

Management - General

While there is no question that outdoors cats have an impact on wildlife, the extent and significance of this impact is the subject of considerable debate. The controversy surrounding outdoor cats can be traced back at least a century, with contemporary claims of threats to global biodiversity bringing animal welfare and conservation interests directly into opposition, largely over the means of managing conflicts. The irony in this is that cat defenders and cat detractors generally agree that it is in the best interests of cats that they should be shielded from the vagaries of outdoor life. While there are practical ...

Household Perceptions And Patterns Of Crop Loss By Wild Pigs In North India, Bivash Pandav, Lakshminarayanan Natarajan, Ankit Kumar, Ajay A. Desai, Banteibor Lyngkhoi

Human–Wildlife Interactions

Loss to cultivated crops by wild pigs (Sus scrofa) is widespread and can jeopardize low-income farmers. In India, although there is lot of political interest in the problem, efforts to understand the patterns, correlates, and underlying reasons for wild pig conflict continue to be minimal. We quantified loss of wheat (Triticum aestivum) to wild pigs and assessed the spatial patterns of damage in a forest settlement of Van Gujjar (Haridwar, India), which is a dairy-based pastoralist community. We chose a 4-km² cultivated area comprising 400 farmlands (each measuring 0.8 ha and belonging to a family) and assessed crop ...

Interactions Between Humans, Crocodiles, And Hippos At Lake Kariba, Zimbabwe, Ivan Marowa, Joshua Matanzima, Tamuka Nhiwatiwa

Human–Wildlife Interactions

Human–wildlife conflicts (HWCs) are on the increase due to shrinking space that results in increased competition for land, water, and other natural resources between humans and wildlife. Investigating the occurrence of HWCs is important in that the results can be used to formulate better management policies and strategies. In this paper, we describe the nature of HWCs emerging between humans and the Nile crocodile (Crocodylus niloticus) and between humans and the African hippopotamus (Hippopotamus amphibius; hippo) on Lake Kariba, Zimbabwe. Lake Kariba is the second largest manmade lake by volume in the world. Conflicts involving humans and these species ...

Human-Bear Conflict And Community Perceptions Of Risk In The Zanskar Region, Northern India, Kirti Chavan, Sophie M. Watts, Tsewang Namgail

Human–Wildlife Interactions

The Himalayan brown bear (Ursus arctos isabellinus) is an endangered subspecies of brown bear (U. a. spp.) and is found throughout the Himalayan region of south and central Asia. We describe the type of and the current level of human–bear conflict (HBC) with Himalayan brown bears in the Zanskar region of northern India and suggest potential mitigation methods. Between July and September 2018, we interviewed 218 households across the Zanskar region, all of whom had experienced HBC. Participants reported increasing numbers of HBC events in the last 4 years. The most common form of HBC was damage to granaries ...

Ecological Correlates Of Alligator Snapping Turtle Bite Performance, Ashley Herrin Gagnon

MSU Graduate Theses

The Alligator Snapping Turtle (Macrochelys temminckii) is one of many turtle species facing conservation challenges. Nearly extirpated in the 1980s, it is currently the subject of a head-start initiative, of which, any lasting behavioral or physiological effects were—until now—unknown! To evaluate the ability of captive-reared individuals to excel in natural habitats, and to foresee any future research or conservation challenges regarding this animal, I explored a suite of variables that influence bite performance and behaviors including captive or free-ranging status, and environmental conditions including body temperature and season. My results indicated that free-ranging M. temminckii outperform those residing ...

Alienation, Modernization, And Animal Welfare: Human-Animal Relationships At The Farm, State, And Country Levels, Michael D. Briscoe

All Graduate Theses and Dissertations

Our relationships with animals are important for us as humans, for the environment, and for the animals themselves. In this dissertation I look at the relationships between humans and animals at three scales: farm, U.S. state, and country. Specifically, I address how factors like economic growth, technological innovation, and globalization affect human relationships with animals. Understanding how these factors influence human-animal relationships is important for improving these relationships and deciding which directions will most contribute to sustainable outcomes. I address the social factors that influence human-animal relationships in three studies.

In the first study I surveyed and interviewed dairy ...

Characteristics Of Non-Fatal Attacks By Black Bears: Conterminous United States, 2000–2017, Janel M. Scharhag, Cady Sartini, Shawn M. Crimmins, Scott E. Hygnstrom, Jeffrey B. Stetz

Human–Wildlife Interactions

Attacks on humans by bears (Ursus spp.) have increased in recent decades, as both human and bear populations have increased. To help mitigate the risk of future attacks, it is important to understand the circumstances in past attacks. Information and analyses exist regarding fatal attacks by both American black bears (Ursus americanus) and brown bears (U. arctos) as well as non-fatal attacks by brown bears. No similarly thorough analyses on non-fatal attacks by black bears are available. Our study addressed this information gap by analyzing all (n = 210) agency-confirmed, non-fatal attacks by black bears in the 48 conterminous United States ...

Empathy And Fairness In Nonhuman Primates: Evolutionary Bases Of Human Morality, Colt Halter

Intuition: The BYU Undergraduate Journal of Psychology

Darwin offered an evolutionary perspective on the origins of human morality, suggesting that humans share a biological foundation with nonhuman primates. This paper reviews the current literature on moral and prosocial behaviors of nonhuman primates, specifically examining whether nonhuman primates exhibit behaviors that are typical of empathy and fairness. The literature documents that nonhuman primates exhibit empathetic behaviors regarding emotional contagion and sympathetic concern. There is also evidence that nonhuman primates have a sense of fairness, seen in their reciprocal behaviors and aversion to inequity. Taken together, this suggests that there are evolutionary roots of morality, lending empirical support to ...

“We Planted Rice And Killed People:” Symbiogenetic Destruction In The Cambodian Genocide, Andrew Woolford, Wanda June, Sereyvothny Um

Genocide Studies and Prevention: An International Journal

In recent years, genocide scholars have given greater attention to the dangers posed by climate change for increasing the prevalence or intensity of genocide. Challenges related to forced migration, resource scarcity, famine, and other threats of the Anthropocene are identified as sources of present and future risk, especially for those committed to genocide prevention. We approach the connection between the natural and social aspects of genocide from a different angle. Our research emanates out of a North American Indigenous studies and new materialist rather than Euro-genocide studies framework, meaning we see the natural and the social (or cultural) as inseparable ...

Understanding How Temperature Influences European Starling’S Reproductive Success, Grace Fatoyinbo, Sarah Guindre-Parker

Symposium of Student Scholars

Many habitats face fluctuating temperatures year round. The animals that live there are typically able to adjust their behaviors to match these conditions. When temperatures become too extreme, however, it could potentially start having a negative effect on the animal’s reproductive success. In birds, for example, severe climate can affect their eggs and nestlings due to nestlings lacking the ability to thermoregulate. The parents then have to bear the responsibility of thermoregulation for their young, through a behavior called incubation or brooding. European starlings (Sturnus vulgaris) are a species of birds common across the United States where both parents ...

Using Machine Learning Methods To Predict The Movement Trajectories Of The Louisiana Black Bear, Daniel Clark, David Shaw, Armando Vela, Shane Weinstock, John Santerre, Joseph D. Clark

SMU Data Science Review

In 1992, the Louisiana black bear (Ursus americanus luteolus) was placed on the U.S. Endangered Species List. This was due to bear populations in Louisiana being small and isolated enough where their populations couldn’t intersect with other populations to grow. Interchange of individuals between subpopulations of bears in Louisiana is critical to maintain genetic diversity and avoid inbreeding effects. Utilizing GPS (Global Positioning System) data gathered from 31 radio-collared bears from 2010 through 2012, this research will investigate how bears traverse the landscape, which has implications for gene exchange. This paper will leverage machine learning tools to improve ...

Some (Im)Material Girls, Living In (Im)Material Worlds, With Seeds, Stars, And Shit, Matthew Weiderspon

Theses and Dissertations

This writing situates material and gestural vocabularies cultivated in my artwork in relation to my lived experience; primarily my rural upbringing in Colorado. Scattered floor dispersals, calling sounds, and bodily movements desire reconsiderations of hope in precarity through a disorientation of place, association, scale, and language.

Analysis Of Multigenerational Behavioral Effects Of Dietary Benzo[A]Pyrene Exposure In Adult Zebrafish, Mary Beth Gillespie

Honors Theses

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon that is linked to negative reproductive and developmental effects in humans and animals. Because BaP is carcinogenic, and its continued presence in the environment allows it to be inhaled and ingested, better understanding of the effects of BaP is needed. To determine the behavioral effects of BaP exposure, zebrafish were used as a model. Wild-type zebrafish (5D) underwent two separate 21-day dietary exposures to 2.5 and 25 μg BaP/g fish to compare how BaP exposure affects locomotor activity. Following the dietary exposure, fish were mated to obtain and raise ...
