Simulating vegetation shifts and carbon cycling in Yosemite National Park

Creator:: Conklin, David R.
Abstract:: The vegetation in Yosemite National Park changed during the 20th century and may change in the 21st century in response to climate change. Vegetation surveys made during the 1930s and the 1990s provide benchmark records separated by 60 years. This study uses the MC1 dynamic global vegetation model to forecast...

Carbon dynamics following landscape fire: influence of burn severity, climate, and stand history in the Metolius Watershed, Oregon

Creator:: Meigs, Garrett W.
Abstract:: Fire is a fundamental disturbance that drives terrestrial and atmospheric carbon dynamics. Previous studies have quantified fire effects on carbon cycling from local to global scales but have focused nearly exclusively on high-severity, stand-replacement fire. Since 2002, variable-severity wildfires have burned more than 65 000 ha across the east slope...

Spatial and temporal variability of carbon dynamics in a tropical forest of Colombia

Creator:: Sierra, Carlos Alberto
Abstract:: Despite the importance of tropical forest ecosystems in the global carbon cycle, there have been few studies of carbon dynamics in this biome. The magnitude of carbon stocks in the tropics and their changes over time are poorly known since ground-based observations are lacking. In this study, total carbon stocks...

Remote sensing of forest aboveground biomass using the Geoscience Laser Altimeter System

Creator:: Pflugmacher, Dirk
Abstract:: Accurate estimates of forest aboveground biomass are needed to reduce uncertainties in the terrestrial carbon flux. The Geoscience Laser Altimeter System (GLAS) onboard the Ice, Cloud and land Elevation Satellite is now the first spaceborne lidar sensor that will provide global estimates of vegetation height. This study investigated the utility...

Remote sensing for monitoring regional carbon dynamics associated with land cover and land use change along the Mesoamerican Biological Corridor

Creator:: Hayes, Daniel J., 1974-
Abstract:: Human activities are causing profound changes to the global environment, yet the potential consequences of these changes on rising atmospheric carbon dioxide and climate change are not well understood. Improving our understanding of these processes requires an enhanced awareness of how global ecosystems are changing and how these changes affect...

Potential carbon storage at the landscape scale in the Pacific Northwest, U.S.A.

Creator:: Smithwick, Erica Ann Hoffa
Abstract:: Estimates of potential carbon (C) storage can be used to constrain predictions of future carbon sequestration and to understand the degree to which disturbances, both natural aid anthropogenic, affect C storage. An upper bound on C storage in the Pacific Northwest (PNW) of the United States was estimated using field...

Carbon storage and fluxes in forests of western Oregon : successional patterns and environmental controls

Creator:: Van Tuyl, Steven
Abstract:: In this study we use a combination of data from forest inventories, intensive chronosequences, extensive sites, and remote sensing, to make estimates of biomass and net primary production (NPP) for the forested region of Western Oregon. Plot-level forest inventory data were provided by the USDA Forest Service through their Forest...

Differences in expression of COVID-19 related inflammatory genes in non-human primates with varying alcohol consumption

Creator:: Co, Amber
Abstract:: Severe cases of COVID-19 have been associated with cytokine storms, leading to widespread inflammation, tissue damage, and organ failure. Pro-inflammatory cytokines have also been shown to play a role in liver diseases, including alcoholic liver disease. To investigate alcohol consumption as a risk factor for SARS-CoV-2 infections and COVID-19 severity,...

Potential for Using Boron Compounds with Differing Water Solubilities in Pastes for Remedial Treatment of Utility Poles

Creator:: Uysal, Selim
Abstract:: Boron and boron compounds have been long used for pressure treatment, dip-diffusion, and remedial treatments of wood because of their proven efficacy against fungi and insects. These materials are especially attractive because their high water solubility promotes deeper penetration into wood. Other useful properties of boron include its neutral pH,...

Biological remediation strategy for immobilizing Ag-110m and Cs-134 in soils

Creator:: Whitlow, Jesse Lynn
Abstract:: After contamination of soil in Japan due to the Fukushima Daiichi accident, there has been an increased interest in remediation of radiologically contaminated land. This study investigated the efficacy of a new biological remediation technology developed by Earthfort, an Oregon based company to hold radionuclides at the soil surface. Cesium-134...
