Patterns of mortality in an old-growth mixed-forest of the southern Sierra Nevada, California

Creator:: Smith, Thomas F., Rizzo, David M., and North, Malcolm
Abstract:: Mortality patterns in an old-growth, mixed-conifer forest, in the absence of wildfire, were investigated at the Teakettle Experimental Forest from 2000 to 2002. We tested the hypothesis that after a century of fire suppression, pathogen- and insect-associated mortality (between episodic droughts) would be significantly greater on ingrowth trees (i.e., smaller-diameter,...

Federal Policy, Rural Community Growth, and Wealth Creation: The Impact of the Federal Forest Policy and Rural Development Spending in the Pacific Northwest

Creator:: Chen, Yong and Weber, Bruce
Abstract:: "In this paper, we use community-level data from Oregon’s 234 rural communities, which we define as incorporated cities with less than 50,000 people, to analyze Federal forest policy. We hypothesize that positive policy impacts due to amenity-related migration were confined to nearby communities, while the negative impacts due to mill...

A History of Science and Society in Oregon: Oregon State University's Extension and Experiment Station Publications

Creator:: Kunda, Sue
Abstract:: Sue Kunda explores the history of Oregon's public land-grant college, Oregon State University (OSU), through examples from over one hundred years of the university's Extension and Experiment Station Communications (EESC) publications. More than 8,000 of those publications are NOW available online covering a range of topics including rural homemaking practices,...

Subsurface temperatures beneath Southern Hydrate Ridge

Creator:: Tréhu, Anne Martine
Abstract:: During Ocean Drilling Program Leg 204, 80 in situ measurements of subseafloor temperature were made; 68 of these showed good frictional pulses on insertion and extraction from the seafloor and were used to constrain the subsurface temperature. Considering uncertainties from various sources, uncertainties in the in situ temperatures are estimated...

Ca. Nitrososphaera and Bradyrhizobium are inversely correlated and related to agricultural practices in long-term field experiments

Creator:: Zhalnina, Kateryna, de Quadros, Patricia D., Gano, Kelsey A., Davis-Richardson, Austin, Fagen, Jennie R., Brown, Christopher T., Giongo, Adriana, Drew, Jennifer C., Sayavedra-Soto, Luis A., Arp, Daniel J., Camargo, Flavio A. O., Daroub, Samira H., Clark, Ian M., McGrath, Steve P., Hirsch, Penny R., and Triplett, Eric W.
Abstract:: Agricultural land management, such as fertilization, liming, and tillage affects soil properties, including pH, organic matter content, nitrification rates, and the microbial community. Three different study sites were used to identify microorganisms that correlate with agricultural land use and to determine which factors regulate the relative abundance of the microbial...

Near-offset vertical seismic experiments during leg 204

Creator:: Tréhu, Anne Martine, Bangs, Nathan Lawrence Bailey, and Guerin, Gilles
Abstract:: Three successful vertical seismic profiles (VSPs) were acquired during Ocean Drilling Program (ODP) Leg 204 at South Hydrate Ridge. The data confirm earlier results from ocean bottom seismometer data and analysis of moveout from common midpoint reflection data that the average velocity between the seafloor and the bottom-simulating reflector (BSR)...

Evaluating theories of drought-induced vegetation mortality using a multimodel– experiment framework

Creator:: McDowell, Nate G., Gehres, Nathan, Limousin, Jean Marc, Macalady, Alison, Martínez-Vilalta, Jordi, Mencuccini, Maurizio, Plaut, Jennifer A., Ogée, Jérôme, Robert E., Pangle, Rasse, Daniel P., Ryan, Michael G., Fisher, Rosie A., Sevanto, Sanna, Waring, Richard H., Williams, A. Park, Yepez, Enrico A., Pockman, William T., Xu, Chonggang, Domec, Jean-Christophe, Holtta, Teemu, Mackay, D. Scott, Sperry, John S., Boutz, Amanda, and Dickman, Lee
Abstract:: Model–data comparisons of plant physiological processes provide an understanding of mechanisms underlying vegetation responses to climate. We simulated the physiology of a pi~non pine–juniper woodland (Pinus edulis–Juniperus monosperma) that experienced mortality during a 5 yr precipitation-reduction experiment, allowing a framework with which to examine our knowledge of drought-induced tree mortality....

Changing concentrations of CO, CH₄, C₅H₈, CH₃Br, CH₃I, and dimethyl sulfide during the Southern Ocean Iron Enrichment Experiments

Creator:: Wingenter, Oliver W., Haase, Karl B., Strutton, Peter, Friederich, Gernot, Meinardi, Simone, Blake, Donald R., and Rowland, F. Sherwood
Abstract:: Oceanic iron (Fe) fertilization experiments have advanced the understanding of how Fe regulates biological productivity and air–sea carbon dioxide (CO₂) exchange. However, little is known about the production and consumption of halocarbons and other gases as a result of Fe addition. Besides metabolizing inorganic carbon, marine microorganisms produce and consume...

The Deep Sea and Me : using a science center exhibit to promote lasting public literacy and elucidate public perception of the deep sea

Creator:: Darr, Katherine D., East, Jennifer L., Seabrook, Sarah, Dundas, Steven J., and Thurber, Andrew R.
Abstract:: A critical barrier to effective management of deep-sea resources is a lack of understanding by society of the benefits received from the oceans. To address this knowledge gap, we applied an iterative design-based research methodology to evaluate (1) how to effectively use an exhibit to increase public literacy of the...

Genetic diversity within late-summer run and half-pounder steelhead (Oncorhynchus mykiss) in the Rogue River, Oregon

Creator:: Dayan, David I., Mazur, Steve, Green, Laura J., Wells, Andrew J., Johnson, Marc A., Van Dyke, Daniel J., Samarin, Peter A., Battleson, Ryan D., and O'Malley, Kathleen G.
Abstract:: Anadromous Oncorhynchus mykiss (steelhead) express diverse migratory behaviors and life history strategies. Adult migration timing diversity within steelhead is often categorized into divergent early- and late-migration phenotypes. On the Rogue River in Oregon, adult steelhead return from the ocean during distinct early-summer, late-summer, and winter runs. Additionally, some juvenile steelhead...
