Comparing streambed light availability and canopy cover in streams with old-growth versus early-mature riparian forests in western Oregon

Creator:: Warren, Dana R., Keeton, William S., Bechtold, Heather A., and Rosi-Marshall, Emma J.
Abstract:: Light availability strongly influences stream primary production, water temperatures and resource availability at the base of stream food webs. In headwater streams, light is regulated primarily by the riparian forest, but few studies have evaluated the influence of riparian forest stand age and associated structural differences on light availability. In...

Band alignment at the BaCuSeF/ZnTe interface

Creator:: Zakutayev, Andriy, Tate, Janet, Platt, Heather A. S., Keszler, Douglas A., Barati, Alireza, Klein, Andreas, and Jaegermann, Wolfram
Abstract:: In situ photoemission spectroscopy experiments are used to characterize the interface between ZnTe and the wide band gap p-type semiconductor BaCuSeF. The contact is characterized by a null valence-band offset, a large conduction-band offset, and a chemically graded interface. By applying the transitivity rule for band offset and on the...

Electronic properties of BaCuChF (Ch = S,Se,Te) surfaces and BaCuSeF/ZnPc interfaces

Creator:: Zakutayev, Andriy, Tate, Janet, Platt, Heather A. S., Keszler, Douglas A., Hein, Corinna, Mayer, Thomas, Klein, Andreas, and Jaegermann, Wolfram
Abstract:: BaCuChF (Ch=S,Se,Te) surfaces and BaCuSeF interfaces with zinc phthalocyanine (ZnPc) were studied by photoelectron spectroscopy. BaCuChF compounds oxidize when exposed to ambient atmosphere. Se capping layers were studied as a means to produce representative surfaces for photoelectron spectroscopic measurements. Decapped BaCuSeF surfaces remain O-free and C-free when the Se layer...

The Pacific Northwest Regional Gap Analysis Project Final Report on Land Cover Mapping Methods MRLC Mapzones 2 and 7

Creator:: Grossmann, Emilie B., Kagan, James S., Ohmann, Janet L., May, Heather, Gregory, Matthew Jay, Tobalske, Claudine, and Institute for Natural Resources
Abstract:: This chapter is divided into three main sections. The first section discusses land cover map development. It begins by providing background information on the regional division of labor and the regional land cover legend. It then focuses on our land cover mapping methods, including a description of data sources, the...

Creator:: Zald, Harold S. J., Ohmann, Janet L., Roberts, Heather M., Gregory, Matthew J., Henderson, Emilie B., McGaughey, Robert J., and Braaten, Justin
Abstract:: This study investigated how lidar-derived vegetation indices, disturbance history from Landsat time series (LTS) imagery, plot location accuracy, and plot size influenced accuracy of statistical spatial models (nearest-neighbor imputation maps) of forest vegetation composition and structure. Nearest-neighbor (NN) imputation maps were developed for 539,000 ha in the central Oregon Cascades,...

Climate Divisions for Alaska Based on Objective Methods

Creator:: Bieniek, Peter A., Bhatt, Uma S., Thoman, Richard L., Angeloff, Heather, Partain, James, Papineau, John, Fritsch, Frederick, Holloway, Eric, Walsh, John E., Daly, Christopher, Shulski, Martha, Hufford, Gary, Hill, David F., Calos, Stavros, and Gens, Rudiger
Abstract:: Alaska encompasses several climate types because of its vast size, high-latitude location, proximity to oceans, and complex topography. There is a great need to understand how climate varies regionally for climatic research and forecasting applications. Although climate-type zones have been established for Alaska on the basis of seasonal climatological mean...

A dynamic leaf gas-exchange strategy is conserved in woody plants under changing ambient CO₂: evidence from carbon isotope discrimination in paleo and CO₂ enrichment studies

Creator:: Voelker, Steven L., Brooks, J.

W., Stambaugh, Michael C., Talhelm, Alan F., Tardif, Jacques C., Van de Water, Peter K., Ward, Joy K., and Wingate, Lisa
Abstract:: Rising atmospheric [CO₂], cₐ, is expected to affect stomatal regulation of leaf gas-exchange of woody plants, thus influencing energy fluxes as well as carbon (C), water, and nutrient cycling of forests. Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO₂],...
