The Effects Of Adolescent Chronic Mild Stress: In Female Wistar-Kyoto Rats, Anna Hallowell

The Journal of Purdue Undergraduate Research

Despite years of research to understand under-lying mechanisms and develop more effective treatment approaches for mood disorders, numerous challenges exist. Many chronic stress models are used to study mood disorders, how-ever the majority have been established with adult males. This is problematic considering that affective disorders are more common in women, and generally develop during late adolescence. Studies have indicated fundamental behavioral, physiological, and neural differences between males and females in response to the same external stressors, furthering a need to develop sex-specific paradigms to accurately model the etiology of mood disorders in females. The Wistar-Kyoto (WKY) rat strain is …

Defining The Relationship Between Maternal Care Behavior And Sensory Development In Wistar Rats: Auditory Periphery Development, Eye Opening And Brain Gene Expression, Jingyun Qiu, Preethi Singh, Geng Pan, Annalisa De Paolis, Frances A. Champagne, Jia Liu, Luis Cardoso, Adrián Rodríguez-Contreras

Advanced Science Research Center

Defining the relationship between maternal care, sensory development and brain gene expression in neonates is important to understand the impact of environmental challenges during sensitive periods in early life. In this study, we used a selection approach to test the hypothesis that variation in maternal licking and grooming (LG) during the first week of life influences sensory development in Wistar rat pups. We tracked the onset of the auditory brainstem response (ABR), the timing of eye opening (EO), middle ear development with micro-CT X-ray tomography, and used qRT-PCR to monitor changes in gene expression of the hypoxia-sensitive pathway and neurotrophin …

Further Evaluation Of A Dry Vacuuming Technique For Recovery Of Dna From Handwritten Documents, Christian Hopkins

Student Theses

A previously developed, non-destructive, homemade vacuum method for collecting biological material from handwritten documents had promising DNA results for white copy paper, preserved indented writing, and latent prints. Prior to casework implementation, additional validation experiments are warranted and here the method was tested for different paper substrates. This work describes testing of notebook paper, bank deposit slips, magazine pages, and manila envelopes. The quantity of recovered DNA varied from donor to donor, but the mean quantities showed a trend that can be explained by the different sizes and surface properties of the tested paper types. The rougher paper type, like …

Preliminary Evidence Of The Role Of Medial Prefrontal Cortex In Self-Enhancement: A Transcranial Magnetic Stimulation Study, Birgitta Taylor-Lillquist, Vivek Kanpa, Maya Crawford, Mehdi El Filali, Julia Oakes, Alex Jonasz, Amanda Disney, Julian Keenan

Department of Biology Faculty Scholarship and Creative Works

Humans employ a number of strategies to improve their position in their given social hierarchy. Overclaiming involves presenting oneself as having more knowledge than one actually possesses, and it is typically invoked to increase one’s social standing. If increased expectations to possess knowledge is a perceived social pressure, such expectations should increase bouts of overclaiming. As the medial prefrontal cortex (MPFC) is sensitive to social pressure and disruption of the MPFC leads to decreases in overclaiming, we predicted that transcranial magnetic stimulation (TMS) applied to the MPFC would reduce overclaiming and the effects would be enhanced in the presence of …

To Feed Or Not To Feed: Examining The Effects Of Provisioning Tourism On Nurse Sharks In Caye Caulker, Belize, Carlee Jackson

All HCAS Student Capstones, Theses, and Dissertations

Wildlife tourism is increasing in popularity around the world, creating the need to understand alterations in animal behavior and spatial distributions that may occur due to associated anthropogenic disturbances. Nurse sharks (Ginglymostoma cirratum, Bonnaterre 1788) are commonly used for wildlife tourism within the Caye Caulker Marine Reserve in Belize. Shark and Ray Village (SRV) is a site within the reserve where nurse sharks are consistently fed by tour/snorkel boats to create an interactive experience with tourists, termed provisioning tourism. Prior to this experiment, no studies had been conducted in SRV to evaluate the impact of provisioning tourism (tourism …

Does Devotion To God Push You Away From Science?: Using Religiosity To Assessing The Impact Of The Religion/Science Conflict Perspective On The Choice Of Academic Major Among Undergraduate Students At A Religious Institution, Jonathan Shephard, Tron Wilder, Aaron Corbit

Capstone Research Projects

Religion and science are often perceived to be in conflict. Science is thought to deal with facts and evidence while religion is thought to deal only with faith. This conflict perspective is pervasive in modern society and can manifest itself in many ways. One way it may exert its influence is in the academic decisions made by college students. Students who are less religious may be more likely to choose science majors while those who are more religious may avoid science majors. While research does support this hypothesis in a broad sense, there may be special cases where the impact …

Large Variability In Feeding Behavior Among Crossbred Growing Cattle, David N. Kelly, Roy D. Sleator, Craig P. Murphy, Stephen B. Conroy, Michelle M. Judge, Donagh P. Berry

Department of Biological Sciences Publications

The purpose of this study was to define an extensive suite of feeding behavior traits in growing crossbred cattle and to investigate their phenotypic inter-relationships as well as relationships with other performance and efficiency traits. Time-series feeding behavior data, as well as feed intake and liveweight records, were available for 624 growing crossbred cattle, of which 445 were steers and 179 were heifers. Feeding behavior repeatability estimates were calculated using linear mixed models. Additionally, partial Spearman correlations were estimated among 14 feeding behavior traits, as well as between feeding behavior with both performance and feed efficiency traits, using residuals retained …

Pre-Emptive Detection Of Mature Pine Drought Stress Using Multispectral Aerial Imagery, Nancy Grulke, Jason Maxfield, Phillip Riggan, Charlie Schrader-Patton

Biology Faculty Publications and Presentations

Drought, ozone (O₃), and nitrogen deposition (N) alter foliar pigments and tree crown structure that may be remotely detectable. Remote sensing tools are needed that pre-emptively identify trees susceptible to environmental stresses could inform forest managers in advance of tree mortality risk. Jeffrey pine, a component of the economically important and widespread western yellow pine in North America was investigated in the southern Sierra Nevada. Transpiration of mature trees differed by 20% between microsites with adequate (mesic (M)) vs. limited (xeric (X)) water availability as described in a previous study. In this study, in-the-crown morphological traits (needle chlorosis, …

The Roles Of Inhibition In C. Elegans Locomotion, Lan Deng

Dissertations

Inhibition plays important roles in modulating neural activities at different levels from small synapses to brain regions, and different systems from sensory to motor. To achieve translocation, locomotor systems produce alternation of antagonist muscles, including axial posture and limb movement and alternation. In the nematode C. elegans, a cross-inhibition circuit, involving excitatory cholinergic and inhibitory GABAergic motoneurons, is believed to generate the dorsoventral alternation of body-wall muscles that supports backward undulatory locomotion. This dissertation challenges this prevalent hypothesis, delves into studying different roles of inhibition, and depicts the expression pattern and functional role of ionotropic GABAA receptor, UNC-49, in motoneurons …

Editorial, Your Null Hypothesis Must Be False: Test It Anyway, Frank Corotto

Georgia Journal of Science

A historical criticism of null hypothesis testing is that a null hypothesis cannot be correct in the first place. The reason that many nulls cannot be correct is that what makes a null hypothesis a null hypothesis is its infinite precision. Only an infinitely precise hypothesis can be used to generate an infinitely precise prediction, such as t will be zero. It is around that infinitely precise prediction that we would construct a probability density function. If you are thinking, I just want to know if the difference is significant, and if you mean important, a null …

Investigating The Efficacy Of Dna Damage With Bleach In Forensic Laboratories And At Crime Scenes, Alyssa Tuccinardi

Honors Theses

Household/commercial bleach (6% NaOCl, sodium hypochlorite) degrades DNA through oxidative damage, production of chlorinated base products, and cleavage of DNA strands (breaking it into smaller and smaller fragments). The presence of these lesions significantly impacts the ability to generate a full genetic profile from an evidentiary sample. In fact, knowledge of the damaging effect of bleach on DNA is the basis for its use in forensic laboratories to clean workbenches and prevent cross-contamination of samples between cases. Additionally, bleach is used intentionally by criminals to clean up crime scenes and destroy DNA evidence. A previous study demonstrated that bleach has …

Sylvan Dell Nature Preserve Project, Brian Quinn, Katie Wisotsky, Huthaifa Aladwan

Sylvan Dell Field Station Student Projects

The Sylvan Dell Nature Preserve and Farm in South Williamsport, PA. Sylvan Dell is a 229 acre plot of farmland that contains a wetland on the south section of the property. It lies just south of the West Branch of the Susquehanna River. The first humans we know of to settle on this land were the Susquehannock and later the Haudenosaunee (Iroquois) Native Americans. In the late 18th century, white settlers took the land away from the Haudenosaunee. In the 20th century, the famous ornithologist Robert Porter Allen was influenced by the broad range of bird species that would visit …

Regional Differences In Wild North American River Otter (Lontra Canadensis) Behavior And Communication, Sarah Walkley

Dissertations

This study focuses on the vocalization repertoires of wild North American river otters (Lontra canadensis) in New York and California. Although they are the same species, these two established populations of river otters are separated by a significant distance and are distinct from one another. River otters are semi-aquatic social predators that can be found throughout North America. This is the first study to examine the vocalizations of wild river otters, and results are compared across field sites in the different regions. River otter vocalizations and behaviors in New York were recorded using Bushnell Aggressor trail cameras that …

How Water Level And Irrigation Practices Affect Waterbird Community, Nesting, And Foraging Habitat Use On The Duck Valley Indian Reservation, Jamie L. Burke

Boise State University Theses and Dissertations

Loss of habitat continues to threaten all bird populations. Despite efforts for conservation of wetlands, waterbirds continue to face habitat threats especially in western North America where water resources are limited across the landscape. The White-faced Ibis (Plegadis chihi) is a colonial nesting waterbird of conservation concern that builds nests in emergent vegetation of freshwater wetlands throughout the western United States. An ibis breeding colony site located at the Blue Creek Wetland complex on Duck Valley Indian Reservation may face habitat threats in the future due to plans intended to increase irrigation water use efficiency. Plans include manipulation …

The Effects Of The Atypical Dopamine Uptake Inhibitor Ce-158 On Extracellular Dopamine In The Nucleus Accumbens, Julia Neri

Honors Scholar Theses

Major Depressive Disorder (MDD) is characterized by symptoms such as cognitive dysfunctions, inflammatory changes, and motivational symptoms such as amotivation, fatigue, and anergia. While depressed people are commonly treated by traditional antidepressants such as serotonin reuptake inhibitors (SSRIs), previous studies have reported that SSRI medications do not treat fatigue and anergia symptoms well, and in some cases, can even worsen those symptoms. Subjects treated with dopamine (DA) uptake inhibitors, on the other hand, have been less likely to report symptoms of anergia and fatigue compared to those treated with SSRIs. Common DA uptake inhibitors such as methylphenidate and amphetamines, however, …

Impact Of Animal Programming On Human Attitudes Of Local Wildlife, Ashton Jerger

Undergraduate Honors Thesis Projects

Attitudes towards wildlife can have direct implications on peoples’ interest in conserving local habitats and their overall ecological choices. Attitudes are formed by multiple components of an individual’s life history. However, through interactive, educational experiences, there is a potential to change current attitudes. Animal programs are an example of interactive, educational experiences that provide individuals the opportunity to get up-close to animal ambassadors and participate in engaging conversations about them. An animal program assessment was conducted with the 2019 summer camps at the Ohio Wildlife Center to quantify the changes in peoples’ affiliation for local wildlife and their willingness to …

298— Rural Economic Growth And Disease Intervention In Ghana; The Edward Pettinella '73 Endowed Ambassadorship In Business, Lucas Sutton

GREAT Day Posters

Schistosomiasis is a leading parasitic infection that debilitates many individuals in sub Saharan Africa. Because this parasitic infection involves a snail as an intermediate host, we use a native prawn species as a natural predator to decrease the population of this snail community. This study focuses on Tomefa, a primarily fishing peri-urban community located oi the outskirts of Accra, the capital city of Ghana. A survey was also given to the local community measuring economic characteristics. In the laboratory, Macrobrachium spp prawn exhibit preference of Bulinus snails over Biomphalaria snails while non-parasitic snails were consumed in higher proportion to parasitized …
