The root pathogen, Phytophthora lateralis Tucker and Milbrath,
continues its destructive spread among Port-Orford Cedars (Chamaecyparis
lawsoniana (Murr.) Parl.) of southwestern Oregon. This
thesis concerns spread of the fungus between root systems of
individual trees in a 49-year-old stand predominantly of Port-Orford-
Cedar. The contribution of root grafts to spread...

There is no doubt that adhesive penetration plays an important role in wood bondline joint performance and durability; yet, to date there is no direct experimental evidence linking penetration depth with bond performance. This is, in part, because adhesive penetration is commonly assessed with various 2D microscopy techniques that are...

Bembidion (Sloanephila) tahitiense, sp. nov., is described from Mont Mauru, an isolated massif of Tahiti Nui volcano. Based upon evidence from seven genes (four nuclear protein-coding, one mitochondrial protein-coding, two nuclear ribosomal), its sister group is the Australian B. jacksoniense Guérin-Méneville, with which it shares a synapomorphic spur on the...
A zone of diffuse deformation -600 km-wide extending from northern California to Washington has developed resulting from the oblique subduction of the Juan de Fuca plate beneath North America, and the northwestward migration of the Pacific plate. This zone is marked by a change in structural style from transtension in...
Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...
The 2003-2005 Biennial Report Volume 2 is an executive summary of Oregon's assessment of the Oregon Coastal Coho Evolutionarily Significant Unit (ESU). The assessment provides a detailed analysis that will inform the pending federal decision on whether to list coho as "threatened" under the Endangered Species Act.

Detailed geologic mapping in the Mormon Mountains and
new geophysical data provide significant insight into
contractional and extensional tectonics in southern Nevada,
southwest Utah, and northwest Arizona. The rocks in the
region were complexly deformed during two distinct tectonic
episodes. Numerous interrelated events occurred within each
episode. The first tectonic...
The study examined associations between rural interschool district expenditure allocations and high school student achievement, after accounting for socioeconomic factors. Both cross-sectional and time series per-student expenditure data (1982-1988) were used. Eleven performance criteria were evaluated based on 1985-1988 data. The sample included 27 small Central and Eastern Oregon school...
Elliptical borehole enlargements or "breakouts" caused by systematic spalling of a
borehole wall due to regional maximum horizontal stresses were identified in 18 wells
drilled in the Coast Range and Willamette Valley of western Oregon. The breakouts
generally indicate a NNW to NNE orientation of maximum horizontal compression

The Lateral Lake Area is located 30 km northeast of Dryden in
Echo and Webb Townships in the District of Kenora in northwestern
Ontario. The area has been the focus of molybdenum exploration
since 1906. Most exploration and development has been centered
on the Pidgeon Prospect in Echo Township. Although,...
This Practical Guide is a companion to the video program Communication Strategies for Fire Management: Creating Effective Citizen-Agency Partnerships. The video is designed to assist land management personnel in working collaboratively with citizens for community fi re and fuel reduction strategies.

Ethylene regulates multiple developmental processes during a plant life cycle, but the effect of ethylene on the upregulation of senescence-, stress-, and post-harvest-related genes in forage grasses is poorly understood. In this work, we used quantitative PCR to determine whether ethylene application affected the expression of selected cell-wall degradation related...

Jurassic rocks exposed in the Buckskin Range of the Yerington district,
represent the upper 1 to 2 km of a large magmatic-hydrothermal system with
porphyry copper deposits at 1-4 km depth. These rocks include, from deep to
shallow, the Yerington batholith, the Artesia Lake Volcanics (intruded by the
batholith), and...
Phytophthora lateralis is the causal agent of cedar root rot, a fatal forest pathogen whose principal host is Chamaecyparis lawsoniana (Port-Orford-cedar), a predominantly riparian-restricted endemic tree species of ecological, economical, and cultural importance to coastal Oregon and California. Local scale distribution of P. lateralis is thought to be associated with...
Four new species of fossil mermithids (Nematoda: Mermithidae) are described from amber: Heydenius arachnius n. sp. from a spider (Arachnida: Araneae) in Dominican amber, Heydenius phasmatophilus n. sp., from a walking stick (Phasmatodea: Phasmatidae) in Baltic amber, Heydenius podenasae n. sp. from a moth (Lepidoptera) in Baltic amber and Heydenius...
Access to health care in North Dakota, a frontier state, has been a widely debated policy issue. Historically, the focus of North Dakota health policy efforts has been directed to issues pertaining to the provision of health care services. During the economic recession of the I 980s, an out-migration of...
The Pleistocene Carpinteria basin is an east-trending
northward-verging, faulted syncline containing up to
1220m of partially intertonguing Santa Barbara and
Casitas Formations deposited on previously folded pre-
Pleistocene strata with up to 80° discordance. Structures
subcropping against the unconformity indicate most
of the deformation in the Santa Ynez Range prior...
The Whitewater River area is located directly east of Mt. Jefferson in the Cascades of central Oregon. Approximately 90 mi2 (230 km2) were mapped (scale 1/24,000) and four new K-Ar ages and 151 major element analyses were obtained in a study of the stratigraphic
