A chronosequence of wood decomposition in the boreal forests of Russia

Creator:: Yatskov, Mikhail A.
Abstract:: Coarse woody debris (CWD) decomposition in the Russian boreal forests of the southern taiga zone was studied at four sites located near St. Petersburg in Northwestern Russia, Krasnoyarsk in Eastern Siberia, lrkutsk in the Baikal region, and Khabarovsk in the Russian Far East. This study was part of a broader...

Ecosystem effects of vegetation removal in coastal Oregon Douglas-fir experimental plantations : impacts on ecosystem production, tree growth, nutrients, and soils

Creator:: Yildiz, Oktay
Abstract:: Effects of partial understory removal on belowground and aboveground ecosystem properties were investigated in 5 and 15 yr old Douglas-fir (Pseudotsuga menziesll (Mirb.) Franco) experimental plantations in western Oregon. Seedling survival was not affected by understory removal at age 5 yr. But through age 15 yr, understory removal increased seedling...

Mapping mortality following a long-term drought in a pinyon-juniper ecosystem in Arizona and New Mexico using Landsat data

Creator:: Kirschbaum, Alan A.
Abstract:: Protracted drought in the southwest U.S. has had significant impacts on the region’s keystone ecosystem, the pinyon-juniper (PJ) woodlands. Drought conditions in 9 of the last 10 years, exacerbated by extreme drought in one year, stressed the pinyon pine (Pinus edulis) trees, making them highly vulnerable to native ips beetles...

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...

Climate, management, and forest type influences on carbon dynamics of West-Coast US forests

Creator:: Hudiburg, Tara M.
Abstract:: Net uptake of carbon from the atmosphere (net ecosystem production, NEP) is dependent on climate, disturbance history, management practices, forest age, and forest type. To improve understanding of the influence of these factors on forest carbon flux in the western U.S., a combination of federal inventory data and supplemental ground...

Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:: Janisch, Jack E.
Abstract:: As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

Understanding changes in forest cover and carbon storage in early successional forests of the Pacific Northwest using USDA Forest Service FIA and multi-temporal Landsat data

Creator:: Schroeder, Todd A.
Abstract:: To effectively study dynamic processes like forest succession over long time periods one must effectively integrate data collected at many different times, locations and spatial scales. The purpose of this research is to integrate forest inventory data collected by the USDA Forest Service’s Forest Inventory and Analysis (FIA) Program with...

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...

Expression and Function of Populus Homologs to TERMINAL FLOWER 1 Genes: Roles in Onset of Flowering and Shoot Phenology

Creator:: Mohamed, Rozi
Abstract:: We isolated and characterized the expression of two genes from Populus trichocarpa that are homologous to the TERMINAL FLOWER 1 (TFL1) gene from the model annual plant Arabidopsis. In Arabidopsis, overexpression of the TFL1 gene extends the vegetative growth phase, and the homozygous mutant tfl1 allele causes early flowering and...

Identifying candidate genes associated with cold adaptation in Douglas-fir using DNA microarrays

Creator:: Howe, Dana Kathryn
Abstract:: In forest trees from temperate and boreal regions, cold acclimation is an important adaptive trait that involves changes in gene expression and physiology. Genecological, quantitative genetic, and QTL studies have been used to study the genetics of cold acclimation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), but the genes responsible for...
