Light-Related Photosynthetic Gene Expression And Enzyme Activity In The Heterokont Alga Vaucheria Litorea And Its Symbiotic Partner The Sacoglossan Mollusc Elysia Chlorotica, Kara M. Soule
Electronic Theses and Dissertations
Photosynthesis is comprised of tightly coupled reactions and therefore requires strict matrices of regulation, particularly involving alterations in gene expression and enzyme activity within the nucleus and plastid. Extensive research has been carried out on these light-regulated mechanisms in plants and green algae, however, much less is known in the red algal lineage, including heterokonts. The goal of this study was to investigate the influence of light on photosynthetic gene expression and select enzyme activity in the heterokont alga Vaucheria litorea and its symbiotic partner Elysia chlorotica, a photosynthetic sacoglossan mollusc (sea slug). Elysia chlorotica harbors V. litorea plastids …
Collaborative Research: Differential Expression Of Oxygen-Binding Proteins In Antarctic Fishes Affects Nitric Oxide-Mediated Pathways Of Angiogenesis And Mitochondrial Biogenesis, Bruce Sidell
University of Maine Office of Research Administration: Grant Reports
The polar ocean presently surrounding Antarctica is the coldest, most thermally stable marine environment on earth. Because oxygen solubility in seawater is inversely proportional to temperature, the cold Antarctic seas are an exceptionally oxygen-rich aquatic habitat. Eight families of a single perciform suborder, the Notothenioidei, dominate the present fish fauna surrounding Antarctica. Notothenioids account for approximately 35% of fish species and 90% of fish biomass south of the Antarctic Polar Front. Radiation of closely related notothenioid species thus has occurred rapidly and under a very unusual set of conditions: relative oceanographic isolation from other faunas due to circumpolar currents and …
Community College Student Participation In Undergraduate Research: An Explanatory Case Study For Faculty And Research Mentors, Dana L. Peterson
Community College Student Participation In Undergraduate Research: An Explanatory Case Study For Faculty And Research Mentors, Dana L. Peterson
Electronic Theses and Dissertations
This study adapted the current model of science undergraduate research experiences (URE's) and applied this novel modification to include community college students. Numerous researchers have examined the efficacy of URE's in improving undergraduate retention and graduation rates, as well as matriculation rates for graduate programs. However, none have detailed the experience for community college students, and few have employed qualitative methodologies to gather relevant descriptive data from URE participants. This study included perspectives elicited from both non-traditional student participants and the established laboratory community. The purpose of this study was to determine the effectiveness of the traditional model for a …
