Associations Between Cannabis, Psychosis, And Schizophrenia In Adolescents, Lauren Moment
Associations Between Cannabis, Psychosis, And Schizophrenia In Adolescents, Lauren Moment
Academic Leadership Journal in Student Research
The effects of cannabis use on the brain, mind, and body have been studied for decades. The developing brain, particularly the adolescent and young adult brain, undergoes critical development that makes it especially susceptible to the effects of cannabis use. Among the adverse effects of cannabis use in adolescence and young adulthood, psychosis and psychotic disorders (e.g., schizophrenia) have been examined. The association of cannabis use with schizophrenia was first elucidated in a Swedish study of army conscripts. Specifically, conscripts reported their cannabis use exposure and were followed longitudinally to assess the emergence of schizophrenia. The authors found that those …
Increasing Detection Sensitivity For Rare And Endangered Species In Kansas Through Development Of An Aquatic Environmental Dna Sampling Protocol, Sarah Hallyburton
Increasing Detection Sensitivity For Rare And Endangered Species In Kansas Through Development Of An Aquatic Environmental Dna Sampling Protocol, Sarah Hallyburton
Master's Theses
Anthropogenic global climate change is forcing the mass extinction of wildlife across the globe. Humans depend on freshwater ecosystems for many aspects of life including agricultural production, sanitation, and recreation. Healthy levels of biodiversity in freshwater environments ensure economically beneficial ecosystem services are maintained. Freshwater ecosystems are hotspots for biodiversity and have higher levels of imperiled organisms compared to terrestrial and marine systems. Within freshwater systems, freshwater mussels (Family: Unionidae) are the most imperiled with over 70% of North American species assigned to a conservation class as judged by state or federal management agencies. The objective of this study was …
Influences Of Grazing On Habitat Characteristics, Avian Community Composition And Nesting Bird Abundance Within Cheyenne Bottoms, Ks, Kirsten Granstrom-Arndt
Influences Of Grazing On Habitat Characteristics, Avian Community Composition And Nesting Bird Abundance Within Cheyenne Bottoms, Ks, Kirsten Granstrom-Arndt
Master's Theses
Cheyenne Bottoms is a 41,000-acre prairie-marsh ecosystem in central Kansas. Approximately 8,000 acres of mixed grassland are dedicated for the conservation of bird populations, but little is known about the status of bird communities within these areas. This study took place within grassland areas of Cheyenne Bottoms from May – July 2021. I investigated bird community composition, relative abundance of frequently observed bird species, vegetative characteristics, and similarity of sites across different grazing intensities (continuous, rotational, and non-grazed). The four most common bird species observed were dickcissel (Spiza americana), grasshopper sparrow (Ammodramus savannarum), meadowlark species ( …
A 16s & Its Soil Microbiome Analysis Of Native & Old-World Bluestem Invaded Soils Of Kansas Grasslands, Zachary Nelson
A 16s & Its Soil Microbiome Analysis Of Native & Old-World Bluestem Invaded Soils Of Kansas Grasslands, Zachary Nelson
Master's Theses
Invasive species are becoming an increasing problem throughout the world. Their effect on local ecosystems is detrimental and widespread, harming productive efforts such as biomass accumulation, forcing native species (plant, animals, microbes) out, and ultimately, reducing biodiversity. Investigations of how invasive plants spread are widely studied; however, there has been little to no examination of how native plants influence the microbiome in the surrounding soil. In this study, I performed a fungal and bacterial metagenomic analysis of the soil and root microbiomes of both native grasslands and grasslands invaded by Old-World Bluestem Grasses to help determine if they influence the …
The Impact Of Planting Season And Crop Residue On Germination, Reproductive Success, And Mass Of Native Forbs, Michaela Vonlintel
The Impact Of Planting Season And Crop Residue On Germination, Reproductive Success, And Mass Of Native Forbs, Michaela Vonlintel
Master's Theses
The lack of biodiversity in prairie restorations compared to native prairies is alarming, and restoring this diversity has been a key focus of research and restoration projects for years. This study aims to assess two variables: planting season and plant residue, for achieving success in forb establishment. This research was conducted in a greenhouse using mesocosms that were seeded in spring, summer, and fall with nine forb species. Half of each seasonal treatment received ground cover, while the other half did not. Two hypotheses were formed. The first was that the fall planting will be the most successful seasonal treatment …
Effects Of Aggressive Reed (Phragmites Australis) On Aquatic Communities In A Kansas Reservoir, Allison Pardis
Effects Of Aggressive Reed (Phragmites Australis) On Aquatic Communities In A Kansas Reservoir, Allison Pardis
Master's Theses
Phragmites australis is an Aquatic Nuisance Species (ANS) in Kansas, a non-native reed that threatens lake and river ecology, displaces desirable species, impedes movement of wildlife and humans, that can have detrimental economic effects on communities. The majority of Phragmites research is in brackish ecosystems and the effects of Phragmites in freshwater systems and especially on fishes is undocumented, even as many states and agencies invest substantial resources in management. As freshwater systems face a biodiversity crisis, prevention and control of invasive species is critical. Effective management therefore requires a thorough understanding of the effects these invaders have on ecosystems …
Healing Sanctuary, Kammy Downs
Healing Sanctuary, Kammy Downs
Master's Theses
The natural world has hidden wisdom and resources that are disregarded as we misuse our responsibility to care for them. The benefits of being in tune with nature have been traded for a culture that manipulates nature on the altar of expediency, waste, and unquenchable desire. Healing Sanctuary presents a duality. My work speaks about the relationship between the seen and unseen, represented by ten larger-than-life drawings of medicinal herbal plants that have had a profound physical healing effect on me. At the same time, plants, roots, and seeds create visceral metaphors for mental health. Our accomplishments, outlook on life, …
Efficacy Of Non-Lethal Molecular Methods In Elucidating Distribution Of Gray Treefrog Complex (Hyla Chrysoscelis/Versicolor) In Kansas, Nora K. Lazerus
Efficacy Of Non-Lethal Molecular Methods In Elucidating Distribution Of Gray Treefrog Complex (Hyla Chrysoscelis/Versicolor) In Kansas, Nora K. Lazerus
Master's Theses
Globally, amphibians are the most imperiled vertebrate taxa in part because they rely on both aquatic and terrestrial ecosystems. Specifically, their permeable skin makes them uniquely susceptible to habitat degradation and alteration. Cope’s Gray Treefrog (Hyla chrysoscelis) and the Gray Treefrog (Hyla versicolor) are a diploid-tetraploid, morphologically indistinguishable sister pair of cryptic anurans native to Kansas. Since 1987, the distribution of gray treefrogs in Kanas has extended west but the status of each species in the complex in Kansas is not known beyond its documented combined western expansion. Currently, species identification cannot be determined by nonlethal …

Most plastid genome sequences are assembled from short-read whole-genome sequencing data, yet the impact that sequencing coverage and the choice of assembly software can have on the accuracy of the resulting assemblies is poorly understood. In this study, we test the impact of both factors on plastid genome assembly in the threatened and rare endemic shrub Calligonum bakuense. We aim to characterize the differences across plastid genome assemblies generated by different assembly software tools and levels of sequencing coverage and to determine if these differences are large enough to affect the phylogenetic position inferred for C. bakuense compared to congeners. …
