Soil quality assessment of Willamette Valley soils and root colonization potential by arbuscular mycorrhizal fungi

Creator:: Allen, Natalie M.
Abstract:: Interest in measuring soil quality continues to increase worldwide in view of demands on land productivity and the necessity to preserve soil resources, yet identification of suitable indicators for soil quality assessment is still evolving. This study adapted 10 biological, physical, and chemical indicators of soil quality identified by the...

Natural products studies of the marine cyanobacteria Lyngbya semiplena and Lyngbya majuscula

Creator:: Han, Bingnan
Abstract:: This thesis details my investigations of marine cyanobacterial natural products that resulted in the discovery of eighteen new secondary metabolites. Isolation and characterization of these unique molecules were carried out using different chromatographic techniques and by careful analyses of 1D and 2D NMR data, respectively. Preliminary bioassays of the crude...

Reproductive success and foraging ecology of the rusty blackbird on the Copper River Delta, Alaska

Creator:: Loomis, David M.
Abstract:: The Rusty Blackbird (Euphagus carolinus) has suffered significant population declines across its entire geographic range and the mechanisms associated with this decline are poorly understood. Although much of the Rusty Blackbird breeding habitat in Alaska has remained relatively unaltered by anthropogenic activities, this species continues to decline by an estimated...

Growth rates and species composition of juvenile rockfish (Sebastes spp.) in Oregon’s nearshore and estuarine habitats

Creator:: Gallagher, M. Brett
Abstract:: Identification of critical habitat for all life stages of commercially exploited fish populations is critical for effective management. Despite a clear need for basic biological information on juvenile rockfish life history, there have been very few efforts to describe distribution and habitat of this life stage, particularly along the Oregon...

Biosynthesis, production and structural studies of secondary metabolites in cultured marine cyanobacteria

Creator:: Vulpanovici, Florina Alexandra
Abstract:: This thesis details investigations of marine cyanobacterial secondary metabolism, with emphasis on a strain of Phormidium sp. collected in Indonesia. These studies assessed the effects of nineteen putative elicitor compounds on the growth and metabolite production of five species of marine cyanobacteria, biosynthetic investigation of an intriguing secondary metabolite, phormidolide,...

Biologically active cyclic depsipeptides from marine cyanobacteria

Creator:: Medina, Rebecca A.
Abstract:: This thesis describes the chemical investigation of marine cyanobacteria collected in Madagascar and Panama with an emphasis on the isolation and structure elucidation of medicinally relevant secondary metabolites. A collection of the marine cyanobacterium Lyngbya majuscula from the Radames Islands, Madagascar yielded two new cyclic depsipeptides, radamamides A and B,...

Novel bioactive secondary metabolites from the marine cyanobacterium Lyngbya majuscula

Creator:: Wu, Min, 1963-
Abstract:: Marine algae have been recognized as a rich resource of new and unusual organic molecules with diverse biological properties. The current need to develop new antifungal, anticancer, antibiotic and antiviral drugs has led to an intense research effort into the discovery, isolation and structure determination of potential medicinal agents from...

Cloning and biochemical characterization of the hectochlorin biosynthetic gene cluster from the marine cyanobacterium Lyngbya majuscula

Creator:: Ramaswamy, Aishwarya V.
Abstract:: Cyanobacteria are rich in biologically active secondary metabolites, many of which have potential application as anticancer or antimicrobial drugs or as useful probes in cell biology studies. A Jamaican isolate of the marine cyanobacterium, Lyngbya majuscula was the source of a novel antifungal and cytotoxic secondary metabolite, hectochlorin. The structure...

The influence of houseplants in a child development center on young children's directed attention

Creator:: Harte, J. Davis
Abstract:: The near physical environment is believed to be an integral component in creating quality learning and classroom environments for young children. Free-choice play periods during preschool daily curriculums are a widespread component of preschool early childhood education. Research has demonstrated that the presence of houseplants may be a contributor to...

Novel oxylipins and other bioactive metabolites from marine algae

Creator:: Nagle, Dale George
Abstract:: I have participated in a drug discovery program designed to screen marine algae for inhibitors of cancer-related enzymes, antitumor compounds, antiinflammatory substances, and other agents of potential pharmaceutical utility. Over 1,500 lipid and aqueous extracts of marine plants and animals were surveyed for biomedical potential. Assays designed to screen extracts...
