In an effort to identify seasonal distribution patterns and habitat requirements of coastal cutthroat trout Oncorhynchus clarki clarki, movement of tagged and marked individuals (35 radio-tagged, 753 PIT-tagged, and 5,322 fin-clipped) was monitored over a 14-month period in an isolated watershed in southwestern Oregon. Emigration out of the basin was...
This thesis examines the rhetoric (persuasive
discourse) of the Fourteenth Dalai Lama, the exiled

The aryl hydrocarbon receptor (AHR) is a ligand activated transcription factor that is a member of the basic helix-loop-helix PER-ARNT-SIM (bHLH/PAS) protein family of cellular sensors. The AHR is conserved across multiple animal phyla and is required for proper vertebrate development. A structurally diverse group of chemicals, including polycyclic aromatic...
Billions of pounds of bisphenol A (BPA) are produced annually around the globe for the manufacture of numerous consumer products, including polycarbonate food and water containers, the protective resin linings of food cans, thermal printing paper, and dental fillings. BPA exposure during nervous system development has been associated with learning...
There are more than 87,000 chemicals in current use with little to no toxicity information available. Assessing such a large number of chemicals using traditional methods would take an unreasonable amount of time and money, and require the use a large number of animals. The incorporation of high-throughput in vivo...

Several large wildfires in southwestern Oregon during the summers of 2001 and 2002 provided the opportunity to investigate the impacts of wildfire on northern spotted owls (Strix occidentalis caurina). I used radio-telemetry and demographic surveys to describe demographic performance and habitat selection of spotted owls in the areas burned by...
At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...
Youth in foster care often perform at lower levels academically than those not in foster care. Prior research on the nature of the relationships that affect former foster youth's educational path has been inconclusive. Though it is widely believed that positive relationships with faculty, staff and peers is beneficial for...
A detailed study of iron concentrations measured by the reducible,
reactive ferrous, and extractable methods was conducted in Auke Bay,
Alaska during June 1973 and in Hood Canal, Washington during October
1973 and April 1974. The concentrations by each method were generally
highest at the bottom and decreased towards the...
