Background: Local adaptation, the differential success of genotypes in their native versus foreign environment, arises from various evolutionary processes, but the importance of concurrent abiotic and biotic factors as drivers of local adaptation has only recently been investigated. Local adaptation to biotic interactions may be particularly important for plants, as they associate with microbial symbionts that can significantly affect their fitness and may enable rapid evolution. The arbuscular mycorrhizal (AM) symbiosis is ideal for investigations of local adaptation because it is globally widespread among most plant taxa and can significantly affect plant growth and fitness. Using meta-analysis on 1170 studies …

Fission Yeast As A Model Organism For Fus-Dependent Ycytotoxicity In Amyotrophic Lateral Sclerosis, Alan J. Cone Jan 2016

Fission Yeast As A Model Organism For Fus-Dependent Ycytotoxicity In Amyotrophic Lateral Sclerosis, Alan J. Cone

Browse all Theses and Dissertations

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative motor neuron disease that causes progressive paralysis and death by asphyxiation. There is no cure or effective treatment; however, previous research has identified several genes that appear related to the pathology of ALS. When mutated, these genes result in proteins that gain toxic functions and disrupt normal cellular processes. Fused in Sarcoma (hFUS) is a human transcription factor in the nucleus that binds to DNA and RNA. Mutations in hFUS are associated with both familial and sporadic cases of ALS, frontotemporal lobar degeneration (FTLD), and cancer. In ALS and FTLD, hFUS is mislocalized …

Epigenetics And Shared Molecular Processes In The Regeneration Of Complex Structures, Labib Rouhana, Junichi Tasaki Jan 2016

Epigenetics And Shared Molecular Processes In The Regeneration Of Complex Structures, Labib Rouhana, Junichi Tasaki

Biological Sciences Faculty Publications

The ability to regenerate complex structures is broadly represented in both plant and animal kingdoms. Although regenerative abilities vary significantly amongst metazoans, cumulative studies have identified cellular events that are broadly observed during regenerative events. For example, structural damage is recognized and wound healing initiated upon injury, which is followed by programmed cell death in the vicinity of damaged tissue and a burst in proliferation of progenitor cells. Sustained proliferation and localization of progenitor cells to site of injury give rise to an assembly of differentiating cells known as the regeneration blastema, which fosters the development of new tissue. Finally, …

Dynamic And Static Stretching Are Equally Effective Techniques For Female High School Soccer Players, Morgan Stefanoff Jan 2016

Dynamic And Static Stretching Are Equally Effective Techniques For Female High School Soccer Players, Morgan Stefanoff

The University Honors Program

Female athletes are more likely than males to experience anterior cruciate ligament (ACL) tears. Common mechanisms for ACL injury include anterior tibial shears occurring between 20-30 degrees of knee flexion and knee valgus (adduction). Stretching prior to exercise reduces the likelihood of ACL tears. I tested the hypothesis that dynamic stretching would reduce the likelihood of ACL tears as indexed by a greater range of motion (ROM) and greater joint stability (knee valgus) than static stretching. Twenty-seven healthy female soccer athletes in high school (ages 15-18) participated. The athletes completed a sit-and-reach test for flexibility, squats to assess ROM, and …

Host Location And Host-Associated Divergence In Parasitoids Of The Gall Midge, Asteromyia Carbonifera, Jeffrey L. Howell Jan 2016

Host Location And Host-Associated Divergence In Parasitoids Of The Gall Midge, Asteromyia Carbonifera, Jeffrey L. Howell

Browse all Theses and Dissertations

Some of the world's greatest mysteries are the series of ecological and behavioral processes that promote adaptive radiation: when one species rapidly diverges into multiple descendants due to ecological selective pressures. Selective pressures from natural enemies have the potential to drive such radiations, as has been suggested in the diversification of the goldenrod gall-midge, Asteromyia carbonifera (Stireman et al., 2008, 2012). This complex, multitrophic system involves the midge species complex, their goldenrod host plants (Solidago sp.), and a suite of parasitoid enemies in the diverse wasp superfamily, Chalcidoidea. There is evidence that the midge is undergoing host-associated differentiation (HAD), in …

Investigation Of Exoribonuclease-1 Function In Regulation Of Stem Cells During Planarian Regeneration, Steven Gobinsing Sayson Jan 2016

Investigation Of Exoribonuclease-1 Function In Regulation Of Stem Cells During Planarian Regeneration, Steven Gobinsing Sayson

Browse all Theses and Dissertations

Precise regulation of gene expression is crucial for the maintenance of pluripotency and proper differentiation of stem cells. Due to their exceptional capacity for stem cell-driven regeneration, planarians are ideal models to dissect mechanisms regulating gene expression that secure stem cell function in vivo. While mechanisms of transcriptional regulation of gene expression in stem cells have been extensively investigated, less is known about regulation at the post-transcriptional level. Exoribonuclease-1 (XRN-1) is a conserved enzyme in eukaryotes that catalyzes 5' to 3' exonucleolytic degradation of RNA. XRN-1 is known to be required for proper regeneration of Dugesia japonica. Here, I …

The Development And Validation Of A One Tier Diagnostic Assessment To Test Premedical Students' Misconceptions About Traumatic Brain Injury, Md Hasan Iqbal

Browse all Theses and Dissertations

Since brain injury is common in the United States, it is important for health professionals and the public to have accurate knowledge about traumatic brain injury (TBI). Understanding misconceptions is important for health educators, nurses, and physicians, who work with TBI patients. While previous studies on misconceptions about TBI have been undertaken, these have not focused on pre-medical students, nor utilized validated assessments. The purpose of this study was to develop and validate a one tier diagnostic test with a confidence index to determine premedical students' misconceptions about TBI. Using the theoretical framework suggested by Treagust (1986, 1988, and 1995), …

The Genomics Of Speciation Within The Globally Distributed Blue-Winged Ducks, Joel Thomas Nelson Jan 2016

The Genomics Of Speciation Within The Globally Distributed Blue-Winged Ducks, Joel Thomas Nelson

Browse all Theses and Dissertations

The ability to disperse over long distances can result in a high propensity for colonizing new geographic regions and lead to lineage diversification via allopatric speciation. However, high vagility can also result in gene flow between otherwise allopatric populations, and in some cases, parapatric or divergence-with-gene-flow models of speciation might be more applicable to widely distributed lineages. Here, I used five nuclear introns and the mitochondrial control region to examine divergence, gene flow, and phylogenetic relationships within a cosmopolitan lineage comprising six species, the blue-winged ducks (genus Anas), which inhabit all continents except Antarctica. I found two primary sub-lineages, the …

Parasitoid Communities Of Remnant And Constructed Prairie Fragments In Western Ohio, Michael Drew Sheaffer Jan 2016

Parasitoid Communities Of Remnant And Constructed Prairie Fragments In Western Ohio, Michael Drew Sheaffer

Browse all Theses and Dissertations

The ability of organisms to disperse to, utilize, and persist in novel habitats in a fragmented landscape is vital to the success of many ecosystem restoration and construction efforts. With less than four percent of original tallgrass prairie persisting across its range, conservationists have made efforts to both protect and restore remnant prairies as well as to plant new prairies. Previous studies suggest that restored ecosystems do not support the same levels of biodiversity and ecosystems services as their remnant counterparts. In this study I measured tachinid fly diversity and orthopteran parasitism rates in order to assess ecological similarity of …

Genetic Analysis Of Male-Specific Lethality Between Caenorhabditis Briggsae:: Caenorhabditis Nigoni F1 Hybrids, Vaishnavi Ragavapuram Jan 2016

Genetic Analysis Of Male-Specific Lethality Between Caenorhabditis Briggsae:: Caenorhabditis Nigoni F1 Hybrids, Vaishnavi Ragavapuram

Browse all Theses and Dissertations

Speciation occurs when there is a lack of reproduction due to genetic barriers. These genetic barriers to gene flow are referred as reproductive isolation mechanisms. Pre-zygotic and post-zygotic isolation are types of reproductive isolation mechanisms. In this project, post-zygotic isolation mechanisms were examined. Haldane's Rule states that in F1 hybrids, individuals of the heterogametic sex are less fit than those of the homogametic sex. Darwin's Corollary to Haldane's rule states that there is asymmetry in hybrid progeny between interspecific reciprocal crosses. Crosses done between Caenorhabditis briggsae males to Caenorhabditis nigoni females produce viable F1 hybrid females and males, yet the …

Genomic Signatures Of Population History In A Pair Of Recently Diverged Australian Teal Support Strong Selection On The Z Sex-Chromosome, Kevin Kyle Hawkins

Browse all Theses and Dissertations

Sex chromosomes are thought to be an important component of the genome associated with speciation and the buildup of reproductive isolation. Recent advances in sequencing technologies and improvements in population genetics and modeling techniques have made it possible to better assess genomic signatures of selection, genetic drift and gene flow in diverging lineages. Recent studies have shown elevated differentiation on the Z sex-chromosome between the Australian grey teal (Anas gracilis) and chestnut teal (Anas castanea). Here, we used next generation sequencing to scan ~3,400 autosomal loci and ~190 Z loci to examine genomic differentiation and signatures of selection and gene …

Chemosensitivity In Mealworms And Darkling Beetles (Tenebrio Molitor) Across Oxygen And Carbon Dioxide Gradients, Andrew King Patterson Jan 2016

Chemosensitivity In Mealworms And Darkling Beetles (Tenebrio Molitor) Across Oxygen And Carbon Dioxide Gradients, Andrew King Patterson

Browse all Theses and Dissertations

Breathing in most insects is controlled through a negative feedback loop consisting of signals (O2, CO2, pH), sensors (chemoreceptors), integrators (neural ganglia), and effectors (spiracles over tracheae). I hypothesized that mealworms and their adult counterparts Darkling beetles, Tenebrio molitor, can sense anoxic and hyperoxic environments and preferentially avoid these environments. I also hypothesize that mealworms are attracted to hypercarbia while Darkling beetles avoid hypercarbia. I constructed a test arena to create an O2 or CO2 gradient. Velocity, total distance traveled, and time spent in each area of the O2 or CO2 gradients …

Suppression Of F1 Male-Specific Lethality In Caenorhabditis Hybrids By Cbr-Him-8, Vaishnavi Ragavapuram, Emily Elaine King, Scott Everet Baird

Biological Sciences Faculty Publications

Haldane's Rule and Darwin's Corollary to Haldane's Rule are the observations that heterogametic F1 hybrids frequently are less fit than their homogametic siblings and that asymmetric results often are obtained from reciprocal hybrid crosses. In Caenorhabditis, Haldane's Rule and Darwin's Corollary have been observed in several hybrid crosses, including crosses of Caenorhabditis briggsae and Caenorhabditis nigoni. Fertile F1 females are obtained from reciprocal crosses. However, F1 males obtained from C. nigoni mothers are sterile and F1 males obtained from C. briggsae die during embryogenesis. We have identified cbr-him-8 as a recessive maternal-effect suppressor of F1 hybrid male-specific lethality …

Sidestream Smoke Exposure Increases The Susceptibility Of Airway Epithelia To Adenoviral Infection, Priyanka Sharma, Abimbola O. Kolawole, Susan B. Core, Adriana E. Kajon, Katherine J.D.A. Excoffon

Biological Sciences Faculty Publications

Background: Although significant epidemiological evidence indicates that cigarette smoke exposure increases the incidence and severity of viral infection, the molecular mechanisms behind the increased susceptibility of the respiratory tract to viral pathogens are unclear. Adenoviruses are non-enveloped DNA viruses and important causative agents of acute respiratory disease. The Coxsackievirus and adenovirus receptor (CAR) is the primary receptor for many adenoviruses. We hypothesized that cigarette smoke exposure increases epithelial susceptibility to adenovirus infection by increasing the abundance of apical CAR. Methodology and Findings: Cultured human airway epithelial cells (CaLu-3) were used as a model to investigate the effect of sidestream cigarette …
