Two experiments were conducted to investigate the effects of
p, p'-DDE and p, 'Dr-DDT on the performance of Coturnix quail (Co-.
turnix coturnix japonica) fed an adequate and deficient calcium diet.
In Experiment I four hundred day-old Coturnix quail of mixed
sex were fed 0 and 50 ppm of p,...
Hair is an important piece of evidence in forensic and archaeological investigations. Analysis of the morphological features of hair has been reported since at least the early 1800's. However, many questions still remain unanswered such as, how can human groups (or local populations) be analyzed and possibly distinguished from each...
In 2004 the National Toxicology Program published an article describing their intent to pursue toxicology testing and risk assessment practices solely reliant on high throughput in vitro datasets and in silico modeling for dose-response assessments. Support and contributions form regulatory agencies and a significant portion of the life sciences community...
In this memoir, by alumnus and Zoology Department instructor William J. Gilstrap, the author details various aspects of his life, including: childhood in Missouri, student experience at Oregon Agricultural College (OAC) in the 1890s, and his medical practice in various Oregon locales. Gilstrap also describes in this narrative the origins...
As important ecological cornerstones, coral reefs face threats from a myriad of sources, such as global climate change, and importantly, disease, the latter often as a result of microbial pathogens. An understudied group of major corals, fire corals, and their even less understood microbiome present an opportunity to learn more...
A survey of natural regeneration of Doug1as-fir and associated species was made on 15 staggered-setting cuttings four and five years after logging. These areas were on the H. J. Andrews Experimental Forest which is located in the McKenzie River area of western Oregon. Five types of cuttings were represented: (1)...
Growth strata geometries and deformed geomorphic surfaces reflect the shorttimescale growth of Sierra de Villicum (San Juan Province, Argentina). Accumulated deformation in repeated earthquakes is recorded by the structural geometry of deformed geomorphic surfaces. Through geologic mapping and topographic surveying, six strath terraces were identified on the eastern flank of...
Kinematic tectonic models constrained by Airy isostatic equilibrium demonstrate the crustal-scale evolution of the Brooks Range during ocean basin closure, arc-continent collision, and exhumation of the orogen. The Bouguer gravity anomaly low that develops across the orogen is related by wavelength to the amount of shortening during collision, and by...
