Moles belong to the mammalian order Insectivora,
the insect eaters. Often, however, they are lumped
incorrectly with the rodents, which include mice, rats,
squirrels, and other gnawing mammals in the order Rodentia.

I used field experiments to study how plants in two grassland communities colonized
soil mounds made by the Camas pocket gopher, Thomomys bulbivorus (Richardson). I
identified potential mound colonizers in each source of colonization (buried propagule bank,
seed rain, and established vegetation) and then measured species specific rates of
colonization...
Home range, dispersal, homing and density of Townsend's mole, Scapanus townsendii (Bachman), were studied during 1964 near Tillamook, Oregon. Additional information on the success of marking
and capture techniques and the response of moles to flooding was gathered. This study was initiated to supply information which might aid in the...

The objective of this study was to determine the
feeding habits of the Mazama pocket gopher (Thomomys
mazama Merriam) in the pine region of south-central
Oregon. Damage caused by pocket gophers to conifer
regeneration was a major incentive for this research.
A permanent reference collection, consisting of
epithelial tissue from...
Reduction of pocket gopher damage to conifer seedlings is important to successful reforestation in many regions of the Pacific
Northwest. The objective of this study was to determine the factors that influence the local distribution of the northern pocket gopher (Thomomys talpoides Richardson) in a forested region of south-central Oregon....

Pocket gophers girdle (remove bark from) the bases of conifer seedlings and saplings, causing significant economic losses.
This publication will help you design a program to reduce or eliminate
gopher damage to seedlings and saplings in your forest plantation or
Christmas tree farm.

Townsend's mole, Scapanus townsendii (Bachman), was
studied by live trapping, dead trapping, and observation
from July 1961, to July 1963, in Tillamook County,
Oregon. This study was initiated at the request of Tillamook County farmers to determine biological facts that
would assist them in their efforts to control this small...
Phylogenic studies suggest that cells from long-lived species are more resistant to a variety of stressors than short-lived species. However, there is little information on the cellular mechanisms that give rise to increased resistance to stress. Our previous studies have shown that liver proteins from a long-lived species have lower...

Spatial variation in the diet of the northern spotted owl (Strix occidentalis caurina) influences owl home ranges, and understanding this relationship will aid managers in forest management prescriptions that influence spotted owl recovery. This study describes the spatial variation in owl diet based on 4183 prey collected at 114 owl...
Potential problem pests found were Armillaria root disease, pocket gopher, western pine shoot borer, and white pine blister rust. Early detection of problem pests allows management actions to be taken if needed to prevent serious impacts. Unit managers should check the areas periodically and call on pest management specialists to...
Some kinetics of the oxygen requirement of amine oxidases
have been investigated using bovine plasma monoamine oxidase (PAO)
and pea seedling diamine oxidase (DAO). A system is described for
studying enzyme reactions under controlled oxygen tension and in an
O₂-free N₂ atmosphere.
O₂ Km values were determined at two different...
Between 1970 and 1974, data were collected on the distribution and biology of the spotted owl (Strix occidentalis) in Oregon. One-hundred and sixteen pairs and seven single birds were located. Spotted owls occurred throughout the mountains of western Oregon and on the east slope of the Cascade Range at least...
This thesis reports on the crystal growth, fabrication,
modeling and performance of Graded Index-Separate Confinement
Heterostructure laser diodes which contain pseudomorphic InGaAs as the
active region material. Laser epitaxial layers were grown with
different indium mole-fractions, and a constant InGaAs layer thickness
of 10 nm, on both sides of the...
The technique of freeze branding was developed by Dr. R. K. Farrell during the 1960’s as an alternative to fire branding domestic livestock. Today, freeze branding is internationally used for cattle and horse identification. In addition to many species of haired animals successfully freeze branded non-haired animals such as whales,...
This document is a summary of the activities of the Wildlife Division for the period of July 1, 1978 to June 30, 1979. It includes numbers of hunting licenses, increased prices of furs, and both large and small game statistics including elk, bears, pheasants, and quail. The document also discusses...

Many people die yearly worldwide due to diseases associated with aging, and if the
process of aging in humans was more understood, the health of these patients could be
improved. While many biochemical actions are involved with the aging process, loss of
proteostasis has been called one of the most...
Aging is a process that all living species experiences and it also is greatly to study and understand the aging process with the aim of extending human life span. Protein homeostasis is one of the main hall mark of aging. Based on previous data, it observed that cells from long...
This presentation was given in the session, "Non-Traditional Partnerships for Access to Collections" at the 2003 Oregon Library Association annual conference. The session discussed partnerships between technical and public services to explore options, set priorities, and work together to develop new approaches to access. The session explored different types of...
An investigation was conducted to determine the origin of
Mima mounds in Jackson County, Oregon and Thurston County,
Washington. Data on soil morphology, mineralogy, and particle
size distribution were used to test the periglacial ice wedge hypothesis,
the gopher hypothesis, the erosional hypothesis, and the
loess hypothesis.
The results of...
In recent years, measurements of atmospheric carbon dioxide with high precision and accuracy have become increasingly important for climate change research, in particular to inform terrestrial biosphere models. Anthropogenic carbon dioxide emissions from fossil fuel burning have long been recognized to contribute a significant portion of the carbon dioxide in...
As part of the continuing investigation of the thermal cis- 1, 3, 5-hexatriene to 1,3-cyclohexadiene rearrangement, four new trienes and a cross-conjugated pentaene have been prepared and their thermal reactions studied. A new route to the synthesis of highly substituted trienes has been developed. The synthesis of three of these...
