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...

Influence of wetland landscape structure of shorebirds wintering in an agricultural valley

Creator:: Taft, Oriane Williams
Abstract:: Understanding how wetland birds use habitat is pivotal to developing successful and beneficial conservation strategies. Although it has been an ardent topic in forest research for some time, how species interact with the spatial patterning of habitat across a landscape (i.e., landscape structure) has been more or less neglected in...

Transboundary groundwater : geopolitical consequences, commons sense, and the law of the hidden sea

Creator:: Jarvis, William Todd
Abstract:: With 97% of the world’s freshwater resources stored underground, the connection between groundwater resources to the metrics of space, scale and time common to the geographic study of natural resources has not been extensively investigated by geographers. While nearly 240 transboundary aquifers are mapped across the world, a potential “tragedy”...

Institutionalizing sustainability in community colleges : the role of the college president

Creator:: Williams, Peter G.
Abstract:: The purpose of this research study was to describe and improve understanding of the meaning of institutionalized sustainability and the role that a college president plays in institutionalizing sustainability on a community college campus. The following questions guided the research: (a) What does it mean to have sustainability “institutionalized” at...

The effects of three knowledge interventions on novice volunteer tutors' teaching performance with children with developmental disabilities in a motor development lab setting

Creator:: Tindall, Daniel William Sanchez
Abstract:: According to Block (1999), the greatest problem with inclusion in physical education is the lack of personnel support. Most help comes in the form of teacher assistants such as peer-tutors and paraprofessional who receive very little, if any, direction from the general physical education teacher. However, what remains unknown are...

Legislators' perceptions about community colleges' use of alternative funding sources to solve budget shortfalls

Creator:: Klimes, Debra S. E.
Abstract:: The purpose of this study was to discern the nature of legislators' perceptions about community colleges' abilities to generate revenues through alternative funding sources and the resultant effects on state allocations to these colleges. Selected community college-related staff members and legislative staff members in Idaho and Oregon were asked to...

Studies on isoprenoid biosynthesis in Euglena gracilis

Creator:: Kim, Dojung
Abstract:: This dissertation describes studies of isoprenoid biosynthesis in the phytoflagellate Euglena gracilis. Elucidation of a novel isoprerioid pathway, the 2-Cmethyl-D-erythritol-4-phosphate (MEP) pathway, in addition to the generally known mevalonate (MVA) pathway, led to extensive exploration of the distribution of both pathways in a variety of organisms. To date, photosynthetic eukaryotes...

Unraveling tissue regeneration using chemical genetics

Creator:: Mathew, Lijoy K.
Abstract:: The emerging field of regenerative medicine is mainly approached by two different aspects. First is the use of stem cell based models to generate a suite of differentiated cells for therapeutic applications and the alternative approach is to utilize the non-mammalian models that have the inherent capacity to regenerate their...

Comparative foraging ecology of five species of Pacific seabirds : multi-scale analyses of marine habitat use

Creator:: Suryan, Robert
Abstract:: Seabirds are an integral component of marine ecosystems, however, because humans typically observe only snapshots of their lives at sea, our understanding of seabird foraging ecology is often limited. A more complete understanding of the ecological roles of seabirds and identification of critical foraging habitats requires the ability to follow...

Nitrogen and phosphorus dynamics during decomposition of multiple litter types in temperate coniferous forests

Creator:: van Huysen, Tiffany L.
Abstract:: Litter nutrient dynamics contribute significantly to biogeochemical cycling in forest ecosystems. These dynamics may be influenced by site attributes, litter nutrient concentrations, and soil nutrient availability either independently or synergistically. Litter nutrient dynamics were examined in two decomposition studies in temperate coniferous forests of Oregon. I used ¹⁵N-labelled litter of...
