Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...
Yellow starthistle (Centaurea solstitialis L.) is a member of the knapweed
(Centaurea L.) complex. It is poor forage for all livestock and causes
“chewing disease,” a nervous disorder, in horses. Yellow starthistle infests
millions of acres in California and the Pacific Northwest. Infestations range
from scattered plants to dense stands...
Climate sensitivity is generally studied using two types of models. Atmosphere-ocean general circulation models (AOGCMs) include interactive ocean dynamics and detailed heat uptake. Atmospheric GCMs (AGCMs) with slab ocean models (SOMs) cannot fully simulate the ocean's response to and influence on climate. However, AGCMs are computationally cheaper and thus are...

Produced water is a highly saline waste product of oil and gas production, which is generated in larger volumes than the hydrocarbons themselves in the United States. Spillage of produced water is of concern because its high salinity can contaminate soil, surface water and groundwater resources, and kill vegetation, including...
This study explores the lived experiences of first-year, rural, Oregon students in their initial entry to college. Through qualitative research involving one-on-one interviews with 10 participants, the author examines the transition of rural students into higher education, common experiences of rural students in their first term of college, and perceived...

Documentation of the side effects of pesticides on
arthropod natural enemies has expanded rapidly since the
1950's as part of an increase in non-target side effects
literature. Most reviews have been based on empirical
analysis of selected literature. The SELCTV database was
developed to make a larger information base accessible...
This research applies the biologically inspired, artificial evolutionary processes of Genetic Algorithms and Genetic Programming to digital hardware circuit synthesis and minimization. In this new application, three approaches are taken to genetic hardware development. First, as a method for logic synthesis, Genetic Programming is applied to the building of logic...
Aims of this research were to find the time period and specific progestins
reflective of the transition from ovarian source to placental source during early gestation
in mares. An attempt was made to describe an accurate profile of total and individual
progestins in plasma and feces from 64 to 150...
