The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr
Undergraduate Research Symposium
This presentation focuses on the effect of caffeine on bee behavior using behavioral pharmacology methodologies. Researchers trained bumblebees to drink out of artificial flowers, then administered sucrose nectar or caffeinated sucrose nectar during a schedule of progressive and fixed ratios. The finding suggests that caffeine did increase the number of rewards during the fixed ratio, but not in the progressive ratio. However, research is still ongoing as bees continue to be tested..

Eristalis Tenax Movement Behavior In Response To Light, Temperature, And Food, Jeffery J. Zheng, Zdena M. Janderova, Jason D. Lang
Georgia Journal of Science
Drone flies, Eristalis tenax (Diptera: Syrphidae), are important generalist pollinators and visit flowers globally that range widely in color. The flies’ photoreceptors allow them to sense light wavelengths between 300-600 nm and E. tenax exhibit a positive phototactic response. To understand the effects of light on E. tenax movement, we conducted two-choice behavioral tests to determine their phototactic response to different wavelengths of light across the spectrum (ultraviolet to red light, plus full spectrum white light). The drone flies moved most and quickest toward sunlight, with almost twice the percentage of flies moving toward sunlight than toward black and …

Habitat loss due to deforestation is a primary threat to global biodiversity. Clearing tropical rainforests for agriculture leads to forest fragmentation. Forest fragments contain fewer large trees and provide lower food availability for primates compared to continuous forests. Mantled howler monkeys inhabit the increasingly fragmented rainforests of Central and South America and may need to alter their activity and spatial cohesion to mitigate competition and preserve energy in fragments where there is lower quality food. We compared howler monkey activity and spatial cohesion across a small forest fragment (La Suerte Biological Research Station, LSBRS) and a large, continuous forest (La …

Identifying Public Perceptions Towards Precision Dairy Technology Use, Brad Kelly
Theses and Dissertations--Animal and Food Sciences
To remain sustainable, the dairy industry must demonstrate commitment to addressing concerns from the public, such as sustainability and animal welfare. Precision dairy technologies (PDT) are a potential solution to ameliorate this issue, but public perceptions towards PDT are currently underinvestigated. This thesis aims to describe public perceptions towards PDT. Specifically, the objectives are to 1) describe baseline perceptions of the U.S. public towards PDT, 2) determine the effects of framing information about human-animal bond, data transparency, and animal welfare on PDT perceptions, and 3) evaluate how demographic characteristics mediate these perceptions. An online survey was used to measure baseline …
Snake Translocation Policies And Practices Within The United States,

Snake Translocation Policies And Practices Within The United States, Robin E. Bedard, Megan Rottenborn, Emily Taylor
Human–Wildlife Interactions
Human–wildlife conflict with nuisance snakes (Serpentes) is rapidly increasing with human population growth and development rates. Translocation of nuisance snakes has become a widespread practice, aided by social media pages connecting people to volunteer and for-profit snake translocators. However, translocators often struggle to find information and resources from wildlife agencies about the policies required, and some may unintentionally use translocation procedures that disregard the health and survival of the snakes. The goals of this study were to (1) obtain data on policies, permitting, and training required for translocating nuisance snakes in each U.S. state that has snakes and (2) compare …

The Auricular Surface Of Chimpanzees (Pan Troglodytes) As An Indicator Of Age, Kalila Garrison
All Master's Theses
Great ape skeletal remains are scarce and their use in biological profile estimations has been limited. Skeletal remains analysis provides key demographic information and ecological context to the individual. Chimpanzees (Pan troglodytes) share skeletal morphological characteristics with humans, and this study seeks to understand if two noninvasive methods using the auricular surface of the ilium to age human skeletal remains could be applied to chimpanzees. The sample consisted of n = 8 individual left auricular surfaces from known age groups of both sexes. Firstly, the Buckberry and Chamberlain Method assigns numerical values to five different traits on the auricular …

Cooperative Bargaining During Mate Competition: A Test In Male Guppies, Maddisen Bell
All Master's Theses
Competition for mating opportunities among individuals of the same sex is a well-documented phenomenon, yet the extent of cooperation in such contexts remains underexplored. This study aims to investigate the occurrence of cooperative bargaining between two males in scenarios of limited and equal female availability, using non-wild descendants of the Trinidad guppy (Poecilia reticulata) as a model species. Four experimental trials assessed courtship length (in seconds) and male-female and male-male interactions, including courtship and aggressive behaviors based on previous research (Magurran et al., 1991). The analysis included the examination of the duration of courtship, the number of aggressive …

Opioid System's Potential Involvement In Ketamine's Cognitive And Antidepressant-Like Effects In Rats, Fan Zhang
Theses and Dissertations
Depression stands as one of the most pervasive mental health challenges worldwide, including the United States. Conventional antidepressants typically display a delayed onset of therapeutic action (4-8 weeks) and lack efficacy in a substantial portion of patients (over 40% of depressed patients are treatment-resistant). The dissociative anesthetic ketamine, which is a glutamatergic N-methyl-D-aspartate (NMDA) antagonist, has emerged as a promising novel treatment due to its rapid and prolonged antidepressant effects, and it is especially beneficial for treatment-resistant depression. Nevertheless, the precise neurochemical mechanisms underlying ketamine’s antidepressant properties remain elusive, hampering the development of safer and more efficacious treatments. The present …

The Effect Of Mating Pheromone 2,6-Dichlorophenol On Gene Expression In Male Lone Star Ticks (Amblyomma Americanum), Mitchell E. Dyen
Honors Undergraduate Theses
Lone star ticks (Amblyomma americanum) are tick species known for their generalist feeding habits, pursuing blood meals with little preference for specific host species. They are found in the southern and midwestern United States but have been rapidly expanding northward due to climate change and white-tailed deer population expansion. Since they are a zoonotic disease vector, their increased abundance has caused the concurrent increased prevalence of a variety of tick-borne illnesses such as tularemia, heartland virus disease, alpha-gal syndrome, ehrlichiosis, and southern tick-associated rash illness (STARI), which effect both humans and animals alike. This increased prevalence of tick-borne …

Social Interaction, Social Cognition, And Personality In Gartersnakes And Ball Pythons, Morgan Skinner
Theses and Dissertations (Comprehensive)
Snakes are often considered non-social animals. However, this is mostly an untested assumption and the limited research that has been done has shown that snakes interact socially when given the opportunity. Here, the complexity of snake social interactions was explored through a social cognition and personality lens. Group and individual behavioural assays were used to explore flexibility and consistency in social interactions. The results provide evidence that elucidate the function, development, and evolution of these behaviours in snakes. In the first experimental chapter, chapter 2, social network analysis was used to provide a detailed description of aggregation behaviour in 4 …

Human–Wildlife Interactions
Feeding management can be a good strategy for avoiding wildlife–vehicle collisions (WVCs), which are a worldwide concern. In this study, we aimed to identify grass species that capybaras (Hydrochoerus hydrochaeris) reject as feeding material. These species could be planted to make roadsides less attractive to capybaras and, consequently, decrease WVCs involving this species. We planted 3 grass species (Brachiaria decumbens cv. Basilisk, B. hybrid Mavuno, and Zoysia japonica) in 4 blocks, applying a randomized-complete blocks design. The first 2 species we assumed would be rejected, since some animals do not consume them due to their high …

Creative or novel behaviors in bottlenose dolphins (Tursiops truncatus) can be indicators of flexible thinking and problem solving. Over 50 years ago, two rough-tooth dolphins demonstrated creative novel behaviors acquired through reinforcement training in human care. Since this novel training, a variety of species have been trained to respond to this conceptual cue. The current study assessed the creativity of 12 bottlenose dolphins (5 females, 7 males) housed at the Roatan Institute for Marine Sciences (RIMS) in Roatan, Honduras. Individual differences were found across four constructs measured for creativity: fluency, flexibility, elaboration, and originality. Variability in performance occurred across test …

Mild Traumatic Brain Injury In Yucatan Minipigs: Assessing Changes In Approachability And Mechanical Nociception Following Diffuse Central Fluid Percussion Injury, Mark D. Pavlichenko
Theses and Dissertations
Traumatic brain injury (TBI) is a major healthcare concern affecting millions. Symptoms of TBI include sensory sensitivity and social changes that may persist long-term. Due to similarities in cytoarchitecture, metabolism, and inflammation, higher order minipig models are advantageous for translational TBI research, however, there remains a shortage of information regarding their behavioral and sensory sequelae following injury. Therefore, in this study, we assessed changes in sociability and somatosensation in adult male and female Yucatan minipigs for up to one-week following a sham or central fluid percussion injury (cFPI). Specifically, the voluntary human approach task (VHAT) and the forced human approach …
Critically Interrogating Wolf Eradication And Management Policy Through A Settler Colonial Lens: Toward A Compassionate Future,

Critically Interrogating Wolf Eradication And Management Policy Through A Settler Colonial Lens: Toward A Compassionate Future, Karen M. Winter
Antioch University Dissertations & Theses
This largely conceptual multi-article dissertation centers settler colonial theory in a critical interrogation of Wolf eradication and management policy (WEMP) toward the ultimate goal of dismantling injurious structures and systems that brutalize Wolf and other Indigenous animals. Wildlife policy and practice are contemporary manifestations of the long-standing historical project of settler colonialism and its quest for acquisition and ultimate control of Land. Thus, the ongoing hegemonic control of systems of wildlife management and the propensity toward lethal control are also inextricably linked to the oppression of Indigenous worldview about human relationship with the natural world. Settler colonialism, as the nexus …

Developing Resources To Foster Farmed Animal Agency In Sanctuary Education, Emily Tronetti
Antioch University Dissertations & Theses
Farmed animal sanctuaries provide lifelong care to formerly farmed animals. Many strive to educate their community about farmed animals and promote more compassionate lifestyles, such as veganism. Important to this is cultivating empathy and concern for the well-being of individual farmed animals. Essential to well-being is agency, which is the capacity of a living being to engage with their environments and to make choices for themselves. Farmed animals outside of sanctuaries have had their agency systematically suppressed and denied. Sanctuary educators can bring awareness to this and inspire alternative, agency-centered relationships with not only farmed animals but all living beings. …

The Influence Of Anesthesia And Nicotine On Dopamine Signaling In The Rat Dorsal Striatum, Gracie E. Rosenbaum
EWU Masters Thesis Collection
The striatum is highly innervated by dopamine neurons and is involved in movement control (dorsal striatum) reward learning (ventral striatum). Fast-scan cyclic voltammetry (FSCV) is a technique that uses microelectrodes (diameter ~5 μm, length ~150 μm) to monitor dopamine signaling in the brain. Although urethane and isoflurane anesthetics are commonly used in in vivo studies, isoflurane’s potential influence on dopamine signaling has not been thoroughly investigated. In addition to this, the addictive nature of nicotine indicates the importance of understanding its impact of dopamine neurotransmission within the different striatal subregions. Male Sprague-Dawley rats (Rattus norvegicus) 300 – 450 grams were …
