Profiling Zebrafish Developmental Responses to E-Cigarette Flavor Mixtures

Creator:: Holden, Laura, L.
Abstract:: Since 2007, electronic cigarette (e-cigarette) sales in the U.S. have surpassed those of tobacco cigarettes. This is due, in part, to manufacturer’s claims that they are a safer alternative to tobacco cigarettes. However, formaldehyde, acrolein, and diacetyl have been detected in e-cigarettes and public knowledge of e-cigarette composition and potential...

Pseudo-spectral approximations of Rossby and gravity waves in a two-Layer fluid

Creator:: Wolfkill, Karlan Stephen
Abstract:: The complexity of numerical ocean circulation models requires careful checking with a variety of test problems. The purpose of this paper is to develop a test problem involving Rossby and gravity waves in a two-layer fluid in a channel. The goal is to compute very accurate solutions to this test...

Assessment of fluorinated chemicals (FCs) on developmental toxicity in embryonic zebrafish

Creator:: Duong, Lisa
Abstract:: Fluorinated chemicals (FCs) have been used since the 1950s in many industrial and commercial applications because of their unique properties such as chemical inertness, resistance to heat and their ability to repel water and oils. Concerns regarding potential environmental or human health risk from FCs exposure have emerged due to...

Supplemental feeding influences reproductive success of the Hawaiian goose (Branta sandvicensis) at Haleakala National Park, Maui, Hawai'i

Creator:: Tamayose, Joy
Abstract:: Low reproductive success has been typical of high elevation populations of the Hawaiian goose (Branta sandvicensis) or nēnē. Researchers identified predation and inadequate nutrition as limiting factors. Reproductive success remained low in most years despite on-going predator control programs. I used a supplemental feeding program over two breeding seasons in...

Distribution and habitat use of bull trout following the removal of nonnative brook trout

Creator:: Renner, Dirk
Abstract:: Invasion by nonnative brook trout (Salvelinus fontinalis) often results in replacement of bull trout (Salvelinus confluentus) in western North America, but the causal mechanisms are not well understood. Removal of brook trout from 1992 to 2000 from Sun Creek in southern Oregon, provided an opportunity to investigate the changes in...

Behavioral constraints on harlequin duck population recovery from the Exxon Valdez oil spill in Prince William Sound, Alaska

Creator:: Rizzolo, Daniel J.
Abstract:: 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...

Seasonal influences on food availability and diet of coastal cutthroat trout in relation to riparian vegetation

Creator:: Romero, Nicolas
Abstract:: Current riparian management objectives in the Pacific Northwest promote both retention of existing conifers and conversion of hardwood-dominated areas to conifers. Although understanding of relationships between riparian vegetation and salmonid prey availability is growing, temporal variation in these relationships is poorly understood. Seasonal fluxes in availability of aquatic and terrestrial...

Nesting ecology of mallards in the Willamette Valley of Oregon

Creator:: Rickerson, Eric V.
Abstract:: Although widely studied in many portions of North America, little is known about the specific habitat requirements of mallard ducks (Anas platyrhynchos) during the breeding season in western Oregon. I radio-marked 72 female mallards in the Willamette Valley of Oregon in March-April 1995-96 to document wetland habitat selection during pre-nesting...

Bird community patterns of spring-seasonal and semi-permanent wetlands in the Sacramento Valley, California

Creator:: Harris, P. Dawn
Abstract:: Freshwater wetlands in the Sacramento Valley provide breeding, wintering, foraging and stopover habitat for migratory and resident birds. With a loss of 95% of historic freshwater wetlands, the restoration of wetlands on private land could provide important habitat for birds. Documentation and monitoring of bird use on previously restored wetlands...

Effects of forest roads on surface and subsurface flow in southeast Alaska

Creator:: McGee, Katherine E.
Abstract:: Well water levels and ditch flow were used to evaluate road-induced changes in surface and subsurface flow for two sites (Trocadero and Polk) in southeast Alaska. At the Trocadero Site, low water levels before and peak water levels during a storm were used to test for differences in subsurface water...
