From the earliest English colonization to the present day, there
has been interest in astronomy in this country. The purpose of this
thesis is to show how the science of astronomy developed in America
from the earliest observations by educated colonists using imported
instruments and publishing in European journals, to...
Ecologists have studied the responses of pelagic ecosystems
to varying levels of nutrient loading and fish predation on many
different scales ranging from small experimental enclosures to
whole lake systems. There are recurring patterns of response to
these two variables, which are generally predictable on the basis
of biogeographic, behavioral,...
The most abundant clone found in ribosomal RNA clone libraries obtained from the world's oceans belongs to the SAR11 phylogenetic group of environmental marine bacteria. Imaging and counting SAR11 bacterial cells in situ has been an important research objective for the past decade. This objective has been especially challenging due...
The Confederated Tribes of the Umatilla Indian Reservation have begun a program aimed at increasing tribal participation in the farming of Reservation lands. This program is viewed by tribal leaders as a means to regain control of Reservation lands for Indians. The purpose of this study was to identify and...
Concern over the need to provide open space in communities
for recreation and other uses and to estimate the public values
involved is apparent to regional planners. This need, particularly
evident in natural resource planning, indicates that more sophisticated
analytical techniques be developed.
The primary thrust of this study is...
An understanding of the dynamics of individual tree and stand
growth, development, and structural patterns during the immature
formative years of a commercial species is essential to determine
correct thinning practices necessary to attain desired objectives.
This study compared a natural, medium-site Douglas-fir stand
and an adjacent similar stand released...
The objective of this project is the production of a Tillamook
Bay restoration plan which is designed to revitalize the bay's
biological productivity and thereby stimulate economic
opportunity in the region. A selected planning team will assess
the cumulative impacts on the bay from accelerated sedimentation.
The team will develop...
