The pigeon guillemot (Cepphus columba) population in Prince William Sound has failed to recover from declines that occurred both before and after the Exxon Valdez Oil Spill (EVOS). Post-spill studies of pigeon guillemot breeding biology have identified three potential factors limiting recovery: (1) predation on eggs and nestlings; (2) declines...
I investigated the relationship between harlequin duck (Histrionicus histrionicus) behavior and lack of recovery from the Exxon Valdez oil spill in Prince William Sound, Alaska. First, I evaluated the hypothesis that harlequin ducks in winter have little flexibility to increase foraging time in response to disturbance because they are constrained...
The 1989 Exxon Valdez oil spill was a major perturbation of nearshore habitats of Prince William Sound, a wintering area for harlequin ducks (Histrionicus histrionicus). This research was designed to evaluate harlequin duck population recovery from the oil spill from 1995 to 1998, using a demographic approach to assess both...
The Arctic climate system is changing dramatically as a response to rising atmospheric greenhouse gas concentrations. Key indicators of Arctic change include thinning and retreating of Arctic pack ice, thawing permafrost, greening tundra, and rising surface temperatures. The structure of the atmospheric boundary layer influences and is influenced by processes...
The discovery of the methylerythritol phosphate pathway (the MEP pathway) as an alternate pathway for isoprenoid biosynthesis in some organisms including most bacteria, malarial parasites and plants, but not in animals, has stimulated extensive studies in this area. Research has revealed the potential of finding novel antibacterials, antimalarial drugs, and...
This thesis research is a series of five studies dealing
with various aspects of hazelnut quality:
1. Identification of kernel mold and its incidence among
hazelnut varieties.
2. Seasonal development and composition of kernels.
3. Hazelnut oil composition (fatty acids and
tocopherols) of seventeen varieties.
4. Hazelnut oil composition compared...
Despite the advance of biomedical science, infectious diseases remain one of the number one killers in the world. They claim the lives of millions of people annually, particularly in underdeveloped and developing countries. In fact, more than 32% of the health burden in Africa is caused by infectious diseases, e.g.,...
Gaining professional experience via internship is a pivotal career development event for college students, but research indicates that there is class disparity in the access and benefit from of internship. Career counselors on college campuses have a role in facilitating preparation and coordinating systemic supports for equitable access and benefit...
Attention-deficit/hyperactivity disorder (ADHD), the most common childhood neurological disorder in the United States, also affects grown women. But girls with ADHD, who tend towards symptoms of inattentiveness, often go undiagnosed until young adulthood. This is because (a) their symptoms are less obvious than the hyperactivity common in ADHD boys, and...
