"Patterns In The Abundance Of Benthic Algae In Streams", Courtney Wright
"Patterns In The Abundance Of Benthic Algae In Streams", Courtney Wright
Honors Theses
Benthic, microscopic algae are the main drivers of primary productivity in streams. The relationship between the abundance and productivity of benthic algae in streams and lakes and the availability of limiting nutrients, especially soluble reactive phosphorus (SRP), has been extensively studied (reviewed in Allan and Castillo 2007, Larned 2010). However, nearly all of this research has been conducted on the periphyton assemblage found on hard substrates (e.g., stones, wood), while very little work has addressed the factors affecting the abundance of epipelic algae (i.e., the algae associated with depositional (soft) sediments such as sands and silts). One of the few …
Potential Effects Of Elevated Co2 On Pitcher Plant Nectar Composition, Prey Capture, And Inquiline Communities, Deirdre Courtney
Potential Effects Of Elevated Co2 On Pitcher Plant Nectar Composition, Prey Capture, And Inquiline Communities, Deirdre Courtney
Honors Theses
Human activities such as fossil fuel burning and deforestation have contributed significantly to the increasing levels of CO2 in the atmosphere since the industrial revolution. Under the IPCC A1FI emission scenario, we are expected to reach levels as high as 1000 ppm by the end of the century. On average, C3 plants experience a 27% increase in carbon to nitrogen (C:N) ratio under elevated CO2. As a result, C3 plants typically exhibit an increase in carbon-based secondary compounds. Carnivorous plants are a rare type of C3 plant that has adapted to survive in low …

Stability Of Eukaryotic Elongation Factor One Alpha Protein In The Cell, Jennifer Watry
Stability Of Eukaryotic Elongation Factor One Alpha Protein In The Cell, Jennifer Watry
Honors Theses
Eukaryotic Elongation Factor One Alpha (eEF1A) is an abundant protein found in every cell of every organism and is involved in functions concerning protein synthesis and degradation, the cytoskeleton, and signaling. How these functions are regulated is not yet understood for this protein. Regulation of the protein may be controlled by transcription of the genes encoding the protein or the stability and modification of the protein. The goal of this project was to determine the stability of eEf1A proteins in Arabidopsis thaliana. Protein stability was determined by treating tissues with cycloheximide, an inhibitor of protein synthesis. Gel electrophoresis and …
The Effects Of Rose Bengal Application On The Production Of Salicylic Acid In Nahg Tobacco Plants, Nicole Christine Ott
The Effects Of Rose Bengal Application On The Production Of Salicylic Acid In Nahg Tobacco Plants, Nicole Christine Ott
Honors Theses
Plants have the ability to develop resistance to a wide range of pathogens following exposure to a single bacterium, fungus, or virus. This resistance occurs in all tissues, not only those that were previously infected. This mechanisms is termed systemic acquired resistance (SAR). The phenolic compound salicylic acid (SA) has been linked to SAR in tobacco, arabidopsis, and cucumber plants. Oxidative stress also causes SA production, which leads to SAR. An engineered tobacco plant (nahG) that does not have the ability to accumulate SA has been used as a research tool in investigations concerning SA activity. Rose Bengal …
The Effects Of Moist-Heat Treatments And Stratification On Germination Of Prairie Plant Seeds, John E. Stuurwold
The Effects Of Moist-Heat Treatments And Stratification On Germination Of Prairie Plant Seeds, John E. Stuurwold
Honors Theses
Germination of Silphium terebinthenaceum was enhanced by a post-stratification most-heat treatment at 80°C. Tested seeds of four other perennial herbs common to midwestern prairies (Andropogon scoparius, Sorghastrum nutans, Eryngium yuccifolium, and Solidago rigida) showed little adverse or beneficial effects of the heat treatment. Heat treatments alone had little effect on the seeds; the length of stratification periods necessary to effect maximal germination varied. The significance of these findings is examined in the light of related literature on grassland fire ecology.
An Ecological Study Of Coliform Bacteria Associated With Vaccinium Corymbosum, Harry C. Bittenbender
An Ecological Study Of Coliform Bacteria Associated With Vaccinium Corymbosum, Harry C. Bittenbender
Honors Theses
Recent research has shown that there are coliform populations associated with the cultivated high bush blueberry, Vaccinium corynbosum. This study is aimed at determining the ecology of these colofirms, as they are related to blueberry production from the farm to the warehouse. Tests will be made to identify the Salmonella group, those associated with "food poisoning." Total bacterial coliform counts will also be made. This paper is primarily an ecological study of the coliforms found on blueberry farms near Grand Junction, though fruit samples were taken from all warehouses of the M.B.G.A.
