Crustal fissuring on the crest of the southern East Pacific Rise at 17°15′–40′S

Creator:: Wright, Dawn J., Haymon, Rachel M., White, Scott M., and Macdonald, Ken C.
Abstract:: Fissure densities and widths have been mapped along the axial zone of the superfast spreading southern East Pacific Rise (EPR) at 17°15′–40′S with the near-bottom DSL-120 and Argo II imaging systems. We observe that the youngest lava flows (on a relative age scale) are sparsely fissured and that there is...

Crustal fissuring and its relationship to magmatic and hydrothermal processes on the East Pacific Rise crest (9°12′ to 54′N)

Creator:: Wright, Dawn J., Haymon, Rachel M., and Fornari, Daniel J.
Abstract:: The deep-towed Argo I optical/acoustical vehicle and a geographic information system (GIS) have been used to establish the abundance, widths, and spatial distribution of fissures, as well as the relative age distribution of lavas along the narrow (<500 m wide) axial zone of the East Pacific Rise (EPR) from 9°12′...

Biology and chemistry of a meadow-to-forest transition in the Central Oregon Cascades

Creator:: Heichen, Rachel S.
Abstract:: In this study, biological and chemical characteristics were determined for two high-elevation meadow-to-forest transitions located in the Central Oregon Cascades. The chloroform fumigation incubation method (CFIM) was used to determine microbial biomass C(MBC) and the N flush due to fumigation (NF), and meadow values were compared to forest values for...

Children's preceptions of parental responses to sibling quarrels and the qualities of sibling relationships

Creator:: Ozretich, Rachel A.
Abstract:: Children in middle childhood were surveyed in elementary schools to explore possible associations between their perceptions about certain characteristics of their sibling relationships and the ways in which their parents responded to sibling quarrels. An instrument was developed to measure perceptions of types of parental responses and the Sibling Relationship...

Broadening the Benefits from Quota-Based Management in Alaska Commercial Fisheries

Creator:: Baker, Rachel
Abstract:: Four commercial fisheries off Alaska’s coast are managed by transferable quota systems. Implementation of each quota program was controversial, and two programs were mandated by federal legislation rather than standard rulemaking procedure. Pacific halibut and sablefish are managed by individual harvest quota programs, which were designed to maintain a predominantly...

Investigation of microorganisms and DNA from subsuface thermal water and rock from the east flank of Juan de Fuca Ridge

Creator:: Fisk, Martin R., Thorseth, Ingunn H., Urbach, Ena, and Giovannoni, Stephen J.
Abstract:: During Leg 168 of the Ocean Drilling Program, basalts were recovered by drilling and subsurface water was collected with a water sampling tool at Hole 1026B on the east flank of Juan de Fuca Ridge. Microorganisms were found in both types of samples. The microorganisms in the basalt appear to...

Compression wood has little impact on the water relations of Douglas-fir (Pseudotsuga menziesii) seedlings despite a large effect on shoot hydraulic properties

Creator:: Spicer, Rachel and Gartner, Barbara L.
Abstract:: • Compression wood has been shown to reduce stem permeability, but it is not known to what extent it affects leaf‐level processes. Here, we report whole‐plant hydraulic properties of Douglas‐fir (Pseudotsuga menziesii) seedlings induced to form varying amounts of compression wood. • Seedlings were grown under three bending treatments to...

Creator:: Deitering, Anne-Marie and Bridgewater, Rachel
Abstract:: Once the purview of the geeks and the early adopters, social software applications like blogs and wikis have made their way into the mainstream. And it seems that every day more tools emerge: social bookmarking, citation-sharing, RSS and more. Just keeping abreast of new tools and what they do is...

To Act or Not to Act: Context, Capability, and Community Response to Environmental Risk

Creator:: Wright, Rachel A. and Boudet, Hilary Schaffer
Abstract:: Social movement theory has rarely been tested with counterfactual cases, that is, instances in which movements do not emerge. Moreover, contemporary theories about political opportunity and resources often inadequately address the issue of motivation. To address these shortcomings, this article examines 20 communities that are "at risk" for mobilization because...

Needs Assessment for Future US Pear Rootstock Research Directions Based on the Current State of Pear Production and Rootstock Research

Creator:: Elkins, Rachel B., Bell, Richard, and Einhorn, Todd
Abstract:: The area devoted to pear production in the United States (U.S.) is declining due to lack of precocity and high cost of production. The U.S. pear industry currently lacks "modern" orchard systems characterized by compact trees that produce early, high yields of large, high quality fruit. Tall, shaded canopies are...
