The purpose of this research was to develop methods for using geographic information system (GIS) analysis and unsupervised classification of Global Vegetation Index (GVI) images to improve carbon budget estimates of the former Soviet Union (FSU). A GIS was used to locate the geographic distribution and estimate the area of...
In two breeding experiments, straightbred and crossbred rabbits were evaluated for performance characters relating to reproduction, disease resistance, growth and carcass quality. In the first experiment,
New Zealand White CNN) and Flemish Giant (FG) straightbreds and FG sire x (Florida White-New Zealand White dam) terminal-crossbreds (TX) were involved. Reproductive performance...
These studies examined the role of perinatal androgen
in the development of neuroendocrine and behavioral
characteristics of gray-tailed voles, Microtus
canicaudus. When mature, females exhibited alternating
vaginal smear patterns or persistent vaginal
cornification; estrogen and progesterone concentrations
were not correlated with vaginal smear patterns. Corpora
lutea were not observed in...
Port-Orford-cedar (Chamaecyparis lawsoniana) is a forest tree native to
a small area of Oregon and California. A root disease caused by
Phytophthora lateralis causes widespread mortality of Port-Orford-cedar.
This dissertation examines three important elements of the Port-Orford-cedar
P. lateralis pathosystem related to breeding for disease resistance:
use of resistant rootstocks...
The objective of this project was to investigate the fate of ponderosa pine regeneration from seed to established seedling, and to determine the relative influences of several important stand elements on those fates. The project was carried out in a series of observational and experimental recruitment studies in central Oregon....
In this work, Neutron Depth Profiling (NDP) analysis capability has been added to the Oregon State University TRIGA® Reactor Prompt Gamma Neutron Activation Analysis Facility (PGNAA). This system has been implemented with an advanced digital spectroscopy system and is capable of rise time pulse shape analysis as well as coincidence...
Coastal dunes provide a diverse set of ecosystem services including coastal protection against destructive surge and waves during storm events. Dunes are constantly evolving through various stages of response to storm events and post-storm recovery at rates that vary due to a range of drivers including pre-existing morphology, environmental forcing...
Background. As part of the nationwide student completion agenda, the Achieving the Dream (ATD) national reform network was established to help community colleges quickly institute sustainable change scaled to impact all students at the institution in a short period of time. Although ATD has been in existence for over a...
The research‘s purpose was to examine how exemplary community college study abroad programs assisted student participants in acquiring global competence. Three research questions were explored: 1.What issues need to be anticipated when planning a study abroad program for community college students in order to effectively incorporate opportunities for students to...
