The Macroevolution Of Diadromous And Non-Diadromous Clupeiformes., Lindsey Dehaan
The Macroevolution Of Diadromous And Non-Diadromous Clupeiformes., Lindsey Dehaan
Honors Theses
Migration is a common life history strategy across the animal tree of life. This behavior is energetically demanding and may trigger strong selection for the evolution of an optimal ecomorphology to lessen energetic costs, yet the ecomorphology of migratory aquatic species remains poorly understood. Previous studies have demonstrated that migratory fishes exhibit predictable phenotypic patterns in body size evolution in response to evolving migration: migratory fishes are larger than non-migratory fishes. Migratory fishes may also have functional traits (e.g. fin shape) associated with locomotion that have experienced similar selective forces and exhibit predictable evolutionary patterns, resulting in migratory lineages sharing …
Supporting Black Mothers At The Transition: A Collaborative Design Prenatal Coparenting Program, Jordan Ebanaya
Supporting Black Mothers At The Transition: A Collaborative Design Prenatal Coparenting Program, Jordan Ebanaya
Masters Theses
Despite having the highest infant mortality rate of similarly developed nations, infant mortality rates have trended downward in the United States, however, the infant mortality disparity between Black and White infants persists. The causes of the disparity have been traced to social considerations of the mother especially while pregnant. These social situations include racism and discrimination, marital status of the mother, social support and pregnancy intentions, pointing to one commonality: stress. Using Boss and colleagues 2017 Conceptual Model of Family Stress, this study proposes a solution to address some of the social support, or resources, available to the expectant mother; …
Pcr Analysis On The Effects Of Alpha Synuclein Treatment On C6 Rat Glioma Cells, Michael John Helmus
Pcr Analysis On The Effects Of Alpha Synuclein Treatment On C6 Rat Glioma Cells, Michael John Helmus
Masters Theses
Multiple System Atrophy (MSA) is a rare neurological disease that mainly implicates the neuronal protein, alpha synuclein, as being centrally involved in MSA pathology. Despite synucleinopathy dogma, little is known about alpha synucleins role in MSA pathogenesis. The Ide laboratory previously conducted an Affymetrix gene expression study utilizing the post-mortem pons tissue from eight individuals with MSA and five individuals without any known neurological disorders. One conclusion from that study was that downregulation of numerous mitochondrial homeostasis related genes had occurred. It is hypothesized that alpha synuclein can perturb mitochondrial homeostasis through direct interaction with mitochondria. This study utilized Reverse …
Functional Analysis In The Home Setting Of An Older Adult With Neurocognitive Disorder, Emily Norton
Functional Analysis In The Home Setting Of An Older Adult With Neurocognitive Disorder, Emily Norton
Masters Theses
Currently within the behavioral gerontology literature there are no published studies that include a functional assessment in the home setting. The primary goal of the present study was to address this gap by conducting a functional analysis on a challenging behavior of an older adult with neurocognitive disorder in the home. This study occurred in two phases. During phase one, researchers conducted an antecedent functional analysis on the bizarre speech of an 81-year-old female with suspected dementia across four conditions (television on, no interactions initiated; television on, interactions initiated; television off, no interactions initiated; television off, interactions initiated). Results from …
Postactivation Potentiation Effects From Maximal Isometric Contractions Performed At Different Hip Joint Angles, Kyle Derosia
Postactivation Potentiation Effects From Maximal Isometric Contractions Performed At Different Hip Joint Angles, Kyle Derosia
Masters Theses
The purpose of this study was to investigate the differences in vertical ground reaction force (VGRF) production and myoelectric activity after performing maximal isometric contractions at different hip joint angles. 10 healthy, experienced participants reported to the lab on two separate occasions where they performed 3 power cleans at baseline, then 4 maximal isometric deadlifts at either ~50° hip flexion angle (Max) or ~90° hip flexion angle (Min). Following the isometric deadlifts, another 3 power clean trials at 70% 1 repetition maximum were performed and used as a post-test. The isometric deadlifts served as the conditioning contraction (CC) to induce …
Relationship Between One Repetition Maximum Parallel Squat And Jump Squat Peak Power, Corey Klitzke
Relationship Between One Repetition Maximum Parallel Squat And Jump Squat Peak Power, Corey Klitzke
Masters Theses
Jump squats are a simple exercise that can be used to train lower body power. Unlike many other methods of power training, jump squats do not require any specialized equipment (platforms, bumper plates, etc.). Jump squats can be used when other forms of power training are not available or are not allowed. In order to most efficiently train power, the intensity must balance force and velocity. The purpose of this study was to find the intensity that yields the peak power output of a jump squat. 12 participants (9 males, 3 female) participated in the study. Each participant completed a …
Effect Of Caffeine Supplementation On Vertical Jump Performance, Heart Rate Variability, And Electromyography, Collin T. Garner
Effect Of Caffeine Supplementation On Vertical Jump Performance, Heart Rate Variability, And Electromyography, Collin T. Garner
Masters Theses
Research into caffeine’s ability to improve anaerobic performance is inconclusive. Eleven anaerobically trained individuals (mean age: 23.45 ± 1.51 years) participated in this study. Assessments of resting heart rate variability (HRV), exercise heart rate variability, surface electromyography (sEMG), static vertical jump (SJ), and countermovement vertical jump (CMJ) were conducted before and after administration of placebo and caffeinated treatments. Three trials of each vertical jump technique were performed before and after treatment administration. A 60-minute absorption period was utilized for absorption of the treatment following its ingestion. All participants performed testing on two separate occasions, once under the placebo condition and …
Antibiotic Resistant Bacteria Isolated From Michigan Birds - A High School Learning Experience, Cody Benfant
Antibiotic Resistant Bacteria Isolated From Michigan Birds - A High School Learning Experience, Cody Benfant
Honors Theses
Bacteria, extremely small prokaryotic cells, are everywhere throughout the world. One striking thing about bacteria is their size: comparing a 2-micrometer bacterial cell to a 6-foot-tall human is similar in scale to comparing a 6-foot-tall human to the distance between Chicago, IL and Denver, CO! Despite their small size, bacteria are found in almost every ecosystem and environment imaginable. From deep sea hydrothermal vents to the clouds miles in the sky, there are trillions of bacteria flourishing in all of Earth’s ecosystems, performing many important functions in global nutrient cycles. While the majority of bacteria are beneficial to humans, …
Astrogliosis In The Adult Zebrafish Olfactory Bulb During Repetitive Peripheral Damage, Jackson Scheib
Astrogliosis In The Adult Zebrafish Olfactory Bulb During Repetitive Peripheral Damage, Jackson Scheib
Masters Theses
Traumatic brain injuries (TBIs), particularly if repetitive, cause massive disruptions of brain homeostasis, significant loss of neurons, and may result in death. Astrocytes are a type of cell that maintain brain homeostasis and neuronal health. Astrogliosis is a continuum of morphological and functional changes of astrocytes in response to damage. This can be neuroprotective or neurotoxic depending on the severity and type of injury. Global astrocyte scarring is typical of neurotoxic astrogliosis and is the source of secondary injury after TBIs. The adult zebrafish olfactory system is known for its capacity to recover from trauma, however, astrocytes in this system …
The Meaning Of Song Type: Exploring Behavioral Responses Of Field Sparrows To Three Simple Song Types, Eliza Foli
The Meaning Of Song Type: Exploring Behavioral Responses Of Field Sparrows To Three Simple Song Types, Eliza Foli
Honors Theses
The frequency, rate, and overall quality of a male’s song may indicate the singer’s physical quality, either as a threat or as a potential mate, and are used for species recognition. However, the degree to which a song must differ acoustically to communicate different information about the singer remains unclear. Analysis of male field sparrow simple song recorded in southwest Michigan revealed three structurally distinct clusters of simple song that differ in frequency characteristics. We hypothesize that songs in each cluster convey information about the singer and that receivers respond more strongly to songs more similar to their own song. …
Isolation And Characterization Of A Novel Terpenoid From The Needles Of Eastern White Pine (Pinus Strobus), And Its Potential Relation To Climate Change, Samantha Hack
Honors Theses
Climate changes is one of the most serious threats facing the future of our planet, and with is we will see drastic changes to water levels global temperatures, and atmospheric conditions. Modeling future atmospheric conditions is crucial if we are to plan for and mitigate the consequences of climate change – while important, these models will not be useful to future scientists unless various parameters, such as BVOC emission to the atmosphere, are accounted for and included in computer models. Eastern white pine (Pinus strobus) are predicted to be a major component of future climax forests as their abundance increases …
The Correlation Between The Microbiome And Neurodegenerative Disorders Such As Alzheimer Disease, Aurora Mokris
The Correlation Between The Microbiome And Neurodegenerative Disorders Such As Alzheimer Disease, Aurora Mokris
Honors Theses
Recent studies suggest that there are 1.3 times as many microbial cells as human cells in the body (Abbot, 2016). Another study claims that the combined genomes of this microbiota is 150 times that of the human genome (Zhuang & Shen, 2018). If you have ever had the feeling that you are not alone in an empty room you are most certainly correct. Your body is teeming with millions of organisms living in mutualistic symbiosis with you and surrounding microbes, but at times, this seemingly harmonious relationship can be disturbed, resulting in serious physical and psychological changes to the human …
The Effects Of Climate Change And Forest Disturbances On Terpene Production Of White Pine (Pinus Strobus) And Red Pine (Pinus Resinosa) In Northern Michigan, Troy Dehagen
Honors Theses
The secondary impacts that climate change may have on the interactions between forests and the atmosphere through forest disturbances is of increasing interest as the climate continues to change. Anthropogenic climate change, which is a direct result of coal and fossil fuel emissions, is likely to impact forest ecology through increased temperatures and extreme precipitation events, thus increasing the frequency and severity of climate-induced forest disturbances. Forest disturbances may have a secondary impact on the production and emission of biogenic volatile organic compounds (BVOC) within forests. In the presence of oxides of nitrogen (NOx) produced from fossil fuel …
The Presence Of Photoreceptor Sensilla In The Posterior Sucker Of Medicinal Leeches Inferred Through Functional Visual Response., Claire Spivey
The Presence Of Photoreceptor Sensilla In The Posterior Sucker Of Medicinal Leeches Inferred Through Functional Visual Response., Claire Spivey
Honors Theses
Medicinal leeches gather visual input from both its eyecups and photoreceptors across its body surface; each of its 21 midbody segments possesses 14 photoreceptive sensilla. It has been previously established that the posterior sucker is composed of seven body segments that are fused during embryogenesis. Similarly, four body segments fuse to create the anterior brain. There are five bilateral pairs of eyes located on the dorsal surface of the leech’s head and seven bilateral pairs of sensilla distributed over the surface of each midbody segment (Kretz et al., 1975). If no sensilla were lost during the fusion of the seven …
Effects Of Age And Exercise On Density Of Sympathetic Innervation And Localization With Nerve Growth Factor And Glial Cell Line-Derived Neurotrophic Factor In Vascular Tissue, Kori Mecklenburg
Honors Theses
Hypertension is a condition that affects nearly 75 million people in the United States (Merai et al, 2017). To better understand this mostly idiopathic condition, the role of survival factors on arterial innervation must be understood. Nerve growth factor (NGF) and glial cell-line derived neurotrophic factor (GDNF) have been shown to support development and maintenance of the sympathetic nervous system. The aim of this study was to reveal how density of sympathetic innervation changes in mesenteric arteries over time and with six-months of exercise. Additionally, this study aimed to reveal the localization of GDNF and NGF alongside these changes in …
