Creator:: Law, Beverly E.
Abstract:: Remote sensing of variables necessary to estimate net primary production of vegetation over large temporal and spatial scales has been a goal of climate change research. This thesis consists of two studies that address the reliability of satellite and airborne sensors to quantify a basic component of all production models,...
Resource Type:: Dissertation

Creator:: Berterretche, Mercedes
Abstract:: This study aims to compare different methods of obtaining maximum growing season leaf area index (LAI) maps using remote sensing data, LAI and tree cover field data in a boreal forest near Thompson, Manitoba, Canada. The comparison includes aspatial methods such as traditional regression, inverse regression and reduced major axis,...

Creator:: Woolley, Travis J.
Abstract:: Quantifying and modeling processes involved in the global carbon cycle is important to evaluate the temporal and spatial variability of these processes and understand the effect of this variability on future response to changing climate and land use patterns. Biomass accumulation and Net Primary Productivity (NPP) are large components of...

Full Text:: of Net Primary Productivity Across Multiple Spatial Scales in the Western Oregon Cascades: Methods of

Creator:: Licata, Julian A.
Abstract:: Many studies have shown that net primary production in old-growth Douglas-fir/western hemlock forests is lower than in younger forests in similar sites, although the cause is still not clear. One possibility is that overall carbon assimilation, or GPP, is lower in older forests. However, it is difficult to measure GPP...

Creator:: Swenson, Jennifer J.
Abstract:: The hump-shaped relationship that predicts highest species richness (species/unit area) at intermediate levels of productivity was examined for woody plants across the Pacific and Inland Northwest of the U.S. Many studies have examined this relationship at regional scales, but commonly use species range maps and surrogate measures of productivity (e.g....

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...
Resource Type:: Masters Thesis

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...
