Microbial Stoichiometry And Homeostasis Of Nutrient Ratios In Fungi, Desiree Leach May 2010

Microbial Stoichiometry And Homeostasis Of Nutrient Ratios In Fungi, Desiree Leach

Honors Theses

Stoichiometry is the ratio of elements in a substance or microbial biomass. This paper investigates microbial stoichiometry and the responses of microbes to dissolved nutrient concentrations and ratios. The current work assesses both autrotrophic and heterotrophic responses to nutrient enrichment: autotrophic and heterotrophic states are defined mainly by ecosystem primary production and respiration. In ecosystems dominated by autotrophic microbes, nutrient enrichment can lead to increased biomass and biomass-specific rates of primary production. Heterotrophic ecosystems rely on subsides of organic carbon from outside the system. Their enrichment with N and/or P can accelerate microbial respiration rates and result in carbon losses …


Growth Rate Of Mugil Cephalus From Two Isolated Ponds In Huntington Beach State Park, South Carolina, Matthew Vincent May 2010

Growth Rate Of Mugil Cephalus From Two Isolated Ponds In Huntington Beach State Park, South Carolina, Matthew Vincent

Honors Theses

Measurement of growth of the euryhaline teleost Mugil cephalus is quite common in open ocean settings, but growth rates of M. cephalus in isolated areas is non-existent. Two isolated ponds in Huntington Beach State, Horry County, South Carolina were selected to study the growth rate of M. cephalus; Sandpiper Pond with virtual no hydrologic connection to the ocean and Jetty Pond with adequate hydrologic connection to the ocean were the sites of sample collection. Scales from M. cephalus in both ponds were collected then aged by two readers, where agreeing ages were kept in the dataset. A von Bertalanffy growth …

The Northwest Forest Plan: Up To Our Neck In Owls?, Ashley N. Horvat Apr 2010

The Northwest Forest Plan: Up To Our Neck In Owls?, Ashley N. Horvat

Honors Theses

Traversing across the vast Pacific Northwest with the Northern spotted owl (Strix occidentalis caurina), one would experience a dynamic landscape that ranged from areas shrouded with ancient forests, mountains dotted with dense young forests, large swathes of empty habitat from clearcuts, and corridors filled with canopies and a plethora of life. The once vibrant forests that blanketed the Pacific Northwest in an abundance of life and sheltered these rare owls in their canopies were threatened by the removal of these primordial giants in these forests. The wild salmon that journey in record numbers through the cold rivers and …


A River Palimpsest: The Interdisciplinary Value Of Water, Katie Norris Apr 2010

A River Palimpsest: The Interdisciplinary Value Of Water, Katie Norris

Honors Theses

Water is an invaluable natural resource to both human and ecological communities, and is currently threatened by global and local pollution and availability. Hypoxia, climate change and local issues all strain river systems to beyond repair. In light of this, communities and scientists must come together to understand the quality and value of natural resources, such as the Great Miami River, in order to inform policy, management and societal perceptions. The overall purpose of this thesis research project is to utilize interdisciplinary areas together to create a valuable, spatially lateral and chronological baseline picture of the Great Miami River. The …

The Wheat Bzip Factor, Taabf1, Mediates Aba-Induced Gene Expression In Bombarded Barley Aleurone Layers, Benjamin R. Keyser Jan 2010

The Wheat Bzip Factor, Taabf1, Mediates Aba-Induced Gene Expression In Bombarded Barley Aleurone Layers, Benjamin R. Keyser

Honors Theses

The plant hormone Abscisic acid (ABA) plays a central role in maturation and germination in seeds, as well as mediating adaptive responses to abiotic environmental stresses. ABA induces the expression of many genes, including late-embryogenesis-abundant genes such as HVA1. To elucidate the ABA signaling pathway leading to HVA1 expression, we focus on the bZIP factor TaABF1. Analysis of the interplay between ABA and TaABF1 in the aleurone cells of imbibing cereal grains indicated that the two are not additive in their induction of the HVA1 promoter. A synthetic ABA analog, PBI-51, did not specifically inhibit the effect of exogenous ABA …


The Role Of Taabf1 In Abscisic Acid-Mediated Suppression Of 𝒶-Amylase Gene Expression In Cereal Grains, Lauren J. Harris Jan 2010

The Role Of Taabf1 In Abscisic Acid-Mediated Suppression Of 𝒶-Amylase Gene Expression In Cereal Grains, Lauren J. Harris

Honors Theses

The phytohormones gibberellin (GA) and abscisic acid (ABA) regulate important developments events in germinating seeds. Specifically, GA induces the expression of hyrolase genes, like the α-amylase gene Amy32b, which mobilizes starch reserves to be used by the embryo, and ABA suppresses this induction. Recent advancements identified ABA and GA receptors and key components in the signaling pathways, however, the mechanism of crosstalk between the hormones remains largely unknown. To further elucidate the mechanism of ABA suppression of GA-induced genes, we focused on the transcription factor TaABF1, a member of the ABA response element binding factor family. TaABF1 has been shown …


Patterns Of Apoptotic Poly(Adp-Ribose) Polymerase Cleavage Induced By Laromustine And Its Analogs, Adam N. Paine Jan 2010

Patterns Of Apoptotic Poly(Adp-Ribose) Polymerase Cleavage Induced By Laromustine And Its Analogs, Adam N. Paine

Honors Theses

The anticancer prodrug Laromustine (VNP40101M) has produced promising remission rates in clinical trials among leukemic patients relative to currently available chemotherapeutics. Such improvements demand that the agent’s mechanism of action be elucidated. This study aimed to determine the role of poly(ADP-ribose) polymerase (PARP) in Laromustine-induced cell death. Previous studies indicated that the methyl isocyanate produced upon activation of Laromustine is largely responsible for its effective induction of apoptosis. Results reported herein strongly support the activation of a PARP-dependent apoptotic pathway by Laromustine’s carbamoylating and chlorethylating subspecies. Furthermore, it is evident that the Laromustine-induced PARP-dependent apoptosis is primarily attributable to methyl …


Family Ties: Mainstream Environmentalists' Understanding Of Radical Environmentalism In America, Zachary W. Ezor Jan 2010

Family Ties: Mainstream Environmentalists' Understanding Of Radical Environmentalism In America, Zachary W. Ezor

Honors Theses

Environmentalism in the United States manifests itself in numerous ways. While American environmentalists have been grouped into broad camps over the years, observers have struggled to accurately classify the different components of the movement. Lately, environmentalists have been characterized based on their chosen modus operandi. Environmentalists who employ typical interest group tactics of policy advocacy and accept the notion of political compromise can generally be called 'mainstream.' Alternatively, those environmentalists who employ non-conventional strategies like direct action and take a no-compromise stance on environmental issues are typically described as 'radical.' Despite these distinctions, both radical and mainstream environmentalists are parts …


Assessing Genetic Differentiation Among Populations Of The Invasive Plant Impatiens Glandulifera In Maine, Jordan R. Schoonover Jan 2010

Assessing Genetic Differentiation Among Populations Of The Invasive Plant Impatiens Glandulifera In Maine, Jordan R. Schoonover

Honors Theses

The annual herbaceous plant Impatiens glandulifera Royle is native to the Himalayas and is a significant invasive species in Europe. In the past century, it was introduced to the United States, where it has become established in 12 states. This study evaluated genetic differentiation among four Maine populations, to address a theory that posits hybridization of distinct lineages as a trigger for invasiveness. Regions of microsatellite repeats were evaluated at two polymorphic loci for 41 plants sampled from the four populations. A striking finding was that the observed heterozygosity was substantially higher than the heterozygosity expected from random combination of …


The Differential Roles Of D-Pax2 Variants In Regulating Drosophila Eye And Bristle Development, Colin J. O’Shea Jan 2010

The Differential Roles Of D-Pax2 Variants In Regulating Drosophila Eye And Bristle Development, Colin J. O’Shea

Honors Theses

The ability to appropriately interact with the environment is crucial to an organism’s survival. The establishment of functional sensory systems, such as the bristles and eyes in Drosophila, is a critical event during the development of the organism. The transcription factor D Pax2 is involved in the differentiation of the shaft and glial cells in the developing bristle (Kavaler et al., Dev, 126:2261-2272, 1999) and of the cone and primary pigment cells in the developing eye (Fu and Noll, Genes Dev, 11:389-405, 1997). How D-Pax2 contributes to distinct differentiative pathways in different cell types is not known. Recent work by …
