During the Colonial Period, in Mexico there was no rational
forest development policy and, as a result, forest resources were
squandered and to a considerable extent destroyed. During the
Nineteenth Century, a rational forest policy began to be promoted, but
in the end, it was translated into a policy of...
This thesis research consists of an investigation of the human
influences on wildlife in Belize. The study was accomplished by the
collection and analysis of data with respect to land use, habitat
characteristics, and wildlife status in Belize. Requirements and

This report summarizes results of geologic mapping in the South Umpqua Falls region of the Western Cascade Range in Douglas County, southwestern Oregon (plate 1). Rocks of the Western Cascades range in age from late Eocene to late Miocene and consist of deformed and partially altered flows, pyroclastic rocks, and...
Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids.
The goal of this work was to investigate turbid runoff during wet-weather...
The essays in this collection do not cluster about a specific theme, nor do they present a single unified interpretative approach to issues in the history of American foreign policy. Above all, William Appleman Williams is a teacher. And good teachers are disappointed with conformity. No one would ever come...
After nearly 20 years of commercial use in orchards without
apparent tree injury in Oregon and Washington, 2,4-D [(2,4-dichlorophenoxy)
acetic acid] was reported in 1970 to cause injury to apple
and pear trees in Washington. In the early 1970's, there was widespread
concern among growers, researchers, and processors in the...

Crops were grown at the experimental farms using accepted cultural practices ( within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with precision plot sprays. Unless otherwise indicated, preplant...

interpretation of specimen material, terminology, and the application
and significance of findings, emphasizing the relationship of dendrochronology procedures to fire history interpretations.
Subterranean clover was grown in nutrient solution and S
deficient Steiwer soil in the greenhouse. Plants were harvested at
15, 30, 45 and 60 days after emergence.

occurred in 15, 30, 45...
An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in
chick blood. Se⁷⁵-selenite is taken up by RBC (13% within 20
minutes) and expelled into the plasma to become bound to proteins. In
contrast, Se⁷⁵-SEM showed a more gradual and continuous buildup...
Field and growth chamber studies were conducted to ascertain
the effects of some environmental factors on the persistence of viable

The average size and age of chinook salmon (Oncorhynchus
tshawytscha) caught in commercial fisheries along the Pacific Coast
of North America have decreased substantially in this century. These
declines might be caused in part by changes in size and age at
maturity within the stocks contributing to those fisheries. Upriver...
The purpose of this study was to investigate the relationship
between kindergarten experience and fine-muscle eye-hand coordination
abilities of first grade children.

Albany, Corvallis, and Salem, Oregon. The mean age of the sample
was 76.69 months with a standard...
The endemic cyprinids of Lake Lanao, Philippines have been described as a species flock and are thought to be an example of explosive evolution. However, based on historical surveys, 16 of the 18 cyprinid species endemic to Lake Lanao are now believed to be extinct. Furthermore, non-native species have been...
Grassland prairies of western Oregon and Washington are among the most endangered ecosystems in the United States.

In the first set of studies, 2 experiments evaluated the influence of supplement composition on ruminal forage disappearance, performance, and physiological responses of Angus × Hereford cattle consuming a low-quality, cool-season forage (8.7 % CP and 57 % TDN). In Exp. 1, 6 rumen-fistulated steers housed in individual pens were...
Staling in beer is inevitable. Oxidation and increased temperatures are the main causes of stale flavors in bottled beers. Since 1934, research has been done to identify compounds and pathways involved in creating stale flavors. Although many research papers report stale flavors, there is not a lexicon per se of...
Two studies were conducted to determine the effect of varying vitamin B-6 (B- 6) status on lymphocyte mitogenic response and pyridoxal 5'-phosphate (PLP) concentration in peripheral blood mononuclear cells (PBMC) in young women. In the first study, women were fed 1 mg/d for the first week and 1.5, 2.1 and...
American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...

Vegetation as a soil-forming factor was studied under forest
transition and grass while attempting to keep other soil forming factors
constant in the western part of the Willamette Valley, Oregon. The
physiographic units consist chiefly of the interior foothills and slopes
formed from an old basaltic flow with some interspersed...
The present study is an attempt to investigate some of the relationships
between certain personality characteristics and expressed
preferences for various communication structures; it is also an
examination of the relative efficiency of the networks used.
Subjects drawn from the university population participated in
experimentally formed five-person groups. These groups...
The Greenbelt Land Trust (GLT) (a grass-roots conservation group in
Oregon) is interested in a conservation plan for the Marys River Corridor. To

Information System (GIS) data base used to compile the inventory (called the
Marys River Project (MRP))....
Accurate estimation of live and dead biomass in forested ecosystems is important for
studies of carbon dynamics, biodiversity, and wildfire behavior, and for forest management.
Lidar remote sensing has been used successfully to estimate live biomass, but studies focusing
on dead biomass are rare. We used lidar data, in conjunction...
