Repeated Treatment With 5-Ht1a And 5-Ht1b Receptor Agonists: Evidence Of Tolerance And Behavioral Sensitization, Jordan Taylor

Electronic Theses, Projects, and Dissertations

Serotonin has been found to regulate several cognitive and physiological functions, and its role in depression and other neuropsychiatric disorders has been a focus of research. More specifically, a wealth of research regarding serotonin focuses on serotonergic medications in the treatment of neuropsychiatric disorders, such as depression and anxiety, and stimulates the 5-HT_1A and 5-HT_1B receptors. Within the last decade, there has been an increase in prescriptions of psychotropic medication for children, however, the efficacy and adverse effects of these drugs have not been evaluated in younger populations. While antidepressants reduce symptoms of depression in adults, they are …

1-Methyl-4-Phenyl-1,2,3,6-Tetrahydropyridine (Mptp)-Treated Adult Zebrafish As A Model For Parkinson’S Disease, Emmeline Bagwell

All Theses

The use of adult zebrafish, Danio rerio, as a model for human neurodegenerative diseases has proven valuable in pharmaceutical development and genetic disease research due to their high genetic homology to humans, cost-effective husbandry, and quick life cycle breeding times. Despite their promise, most zebrafish research has focused on embryonic stage organisms, primarily due to the ease of direct handling protocols and rapid progression through developmental stages. Recognizing the limitations of early-stage organisms in modeling adult diseases, recent efforts have shifted the applicability of zebrafish models, particularly for Parkinson's Disease, due to the nature of the disease impacting patients 55 …

Classification Of Large Scale Fish Dataset By Deep Neural Networks, Priyanka Adapa

Electronic Theses, Projects, and Dissertations

The development of robust and efficient fish classification systems has become essential to preventing the rapid depletion of aquatic resources and building conservation strategies. A deep learning approach is proposed here for the automated classification of fish species from underwater images. The proposed methodology leverages state-of-the-art deep neural networks by applying the compact convolutional transformer (CCT) architecture, which is famous for faster training and lower computational cost. In CCT, data augmentation techniques are employed to enhance the variability of the training data, reducing overfitting and improving generalization. The preliminary outcomes of our proposed method demonstrate a promising accuracy level of …

Demographics, Sexual Dimorphism, And Ecological Aspects Of Ambystoma Annulatum (Ringed Salamander) In Northwest Arkansas, Usa, Brian M. Becker

Graduate Theses and Dissertations

The need to study and monitor amphibian populations is increasing along with the threats to their population stability and persistence in nature. Northwest Arkansas is one of the fastest growing areas in the nation and with that growth comes rapid changes in land use, massive alterations to habitats, habitat loss, and the introduction of nonnative plants and animals. Ambystoma annulatum (Ringed Salamander) is an Ambystomatid endemic to the Ozark and Ouachita Mountains of southern Missouri, northern and western Arkansas, and eastern Oklahoma giving it a relatively small distribution compared to most Ambystoma. Therefore, Arkansas constitutes a significant portion of the …

Habitat Associations Of Plains Spotted Skunk (Spilogale Interrupta) Across The Plains Ecoregion. And The Landcover Occupancy Models Of The Gray Fox (Urocyon Cinereoargenteus) In The Southeastern Plains Region In Arkansas, Michael Shaw

Graduate Theses and Dissertations

Much of the landscape of the United States has been altered by humans, leading to the eradication of most populations of large mammalian predators. Consequently, many species of mammalian mesopredators (medium-sized mammalian predators) have come to dominate the landscape. Species such as the gray fox (Urocyon cinereoargenteus) may appear to be on the rise and doing well due to their widespread range, but at a local scale may need monitoring and less is known in areas of its range. Others such as the plains spotted skunk have a wide range across the plains but are on the decline even with …

Why Humans Kill Animals And Why We Cannot Avoid It, Benjamin L. Allen, Christopher Bobier, Stuart J. Dawson, Peter J S Fleming, Jordan Hampton, David Jachowski, Graham I H Kerley, John D. Linnell, Kelly Marnewick, Liaan Minnie, Mike Muthersbaugh, M Justin O'Riain, Dan Parker, Gilbert Proulx, Michael J. Somers, Keifer Titus

Animal production and livestock research articles

Killing animals has been a ubiquitous human behaviour throughout history, yet it is becoming increasingly controversial and criticised in some parts of contemporary human society. Here we review 10 primary reasons why humans kill animals, discuss the necessity (or not) of these forms of killing, and describe the global ecological context for human killing of animals. Humans historically and currently kill animals either directly or indirectly for the following reasons: (1) wild harvest or food acquisition, (2) human health and safety, (3) agriculture and aquaculture, (4) urbanisation and industrialisation, (5) invasive, overabundant or nuisance wildlife control, (6) threatened species conservation …

Fauna As Fieldworkers: An Analysis On The Use Of Animals As A Form Of Organic Weed And Pest Management In Modern Viticulture, Mariana Del Carmen Campano

Independent Study Project (ISP) Collection

Recent data on the current state of pesticide use in global agriculture suggests serious concerns over significant overuse and negative effects on both environmental and human health, and current trends only suggest continued increases in future global pesticide use. Without prompt, large-scale intervention, this global abuse of chemical pesticides spells significant threats of not only continued harm to global health and environmental quality, but also to the long term viability of agricultural lands and the growing threat of pesticide resistant insects and weeds. Various methods have been explored in the realm of integrated pest management (IPM), but a current lack …

Creating A Framework For An Effective Koala Recovery Center: A Case Study Of Friends Of The Koala, Nsw, Finley Scoular

Independent Study Project (ISP) Collection

Koala populations in New South Wales, Queensland, and the Australian Capital District are currently faced with factors that threaten their survival. Within one decade, their status has shifted from stable to vulnerable to endangered. The cause of this is attributed to increased exposure to dog attacks, vehicle collisions, diseases, and habitat fragmentation and destruction. The koalas' status of endangered in these territories has illuminated the need for human intervention. This study focuses on the specific form of human intervention that involves the rescue, rehabilitation, and release of wild koalas. Due to the recent koala status change from vulnerable to endangered, …

Við Pollurinn: The Effects Of Human-Caused Stimuli On Harbor Seals (Phoca Vitulina) In Ísafjörður, Ella Jorgensen

Independent Study Project (ISP) Collection

Harbor seals are important for the health of Iceland’s marine ecosystems. They are normally seen hauled-out onto land to rest. There are many factors that affect the haul-out patterns of harbor seals including location, season, time of day, tide height, weather, and human-caused stimuli. The presence of human-caused stimuli can also have a negative impact on haul-out patterns and behaviors. The Icelandic harbor seal population is threatened as it has been declining since 1980. Climate change and the rise of tourism in Iceland may be a factor contributing to this decline; and there is a gap in knowledge on the …

Investigating Monodelphis Domestica As An Alternative To The Mus Musculus As An Animal Model, Cristian M. Botello, John L. Vandeberg, Mario Gil

The Implications Of Solidarity For Food Ethics, John Sniegocki

The Journal of Social Encounters

This essay examines numerous ways in which commitments to solidarity have relevance in the area of food ethics. Among the topics explored are food insecurity and hunger, workers’ rights, ecology, and the treatment of animals. Particular attention is paid to the impacts of the production and consumption of animal products. These issues are examined through the lens of the developing understanding of solidarity present in the tradition of Catholic social teaching (CST). The ethical framework provided by CST, it is suggested, could be further enhanced by insights drawn from the growing tradition of “Black veganism” and its holistic, intersectional understanding …

Evaluation Of Heat Abatement Use, Vaginal Temperature, And Activity Of Pregnant, Lactating Holstein Cows Housed On Pasture With Or Without The Choice Between Shade And Sprinklers For Heat Abatement., Kevin M. Braman

Theses and Dissertations

The objective of this thesis was to determine how pregnant, lactating Holstein cows on pasture interact with shade and sprinklers when offered a choice or no-choice between methods. Authors hypothesized that cows would use shade more then sprinklers, but sprinklers would be more effective at cooling cows. Additionally, authors predicted cows using shade more would have decreased lying bouts and steps and an increase in time lying, compared to cows choosing sprinkler. Results indicate cows will use both methods when offered alone or together. However, cows will choose to be exposed or in shade at lower temperature humidity index values, …

Dog Tired: Examining The Relation Between Dog And/Or Cat Ownership And Owners’ Sleep, Courtney J. Bolstad

Theses and Dissertations

Sleep is an essential part of life, and obtaining quality sleep is important for various areas of functioning. Behaviors to promote sleep include physical activity, managing stress, reducing anxiety symptoms, maintaining a consistent sleep schedule, and obtaining bright light exposure. Many of these behaviors overlap with benefits observed from pet ownership (PO). The present study aimed to examine the relation between PO and sleep as well as moderators and mediators of this relation. Four research questions were examined: 1) Is PO significantly related to sleep? 2) Does gender moderate the relation between PO and sleep? 3) Do sleep-promoting behaviors (i.e., …

A Four-Pronged Approach To Addressing A Wild Pig Invasion In A Bottomland And Upland Forested Landscape, Tyler Scott Evans

Theses and Dissertations

Among exotic species that are capable of invading, establishing, and reaching pest status, few pose the range of impacts to biotic (e.g., competition with native species, predation, herbivory, introduction of other exotics) and abiotic (e.g., soil, hydrology) ecosystem components that can be attributed to the wild pig (Sus scrofa). Despite the presence of wild pigs throughout the southeastern United States for centuries, new invasions continue to occur in previously uninhabited and often under-investigated landscapes, including bottomland and upland forests. The recent invasion of the Sam D. Hamilton Noxubee National Wildlife Refuge (hereafter, NNWR) in east-central Mississippi represents an …
