Biogeochemical signals of mountainous forested watersheds' response to disturbance

Creator:: Guerrero-Bolaño Francisco J.
Abstract:: Small mountainous watersheds are disproportionate sources of land-derived particulate organic matter (POM) to long-term sinks like lake bottoms and the ocean. As such, these ecosystems are an essential component of the global carbon cycle. The burial of POM in lacustrine and marine sediments contributes to the drawdown of atmospheric CO2...

Dynamics of water-soluble carbon in forest soils of contrasting fertility

Creator:: Wagai, Rota
Abstract:: Most soil organic C is in a stable form, associated with clay minerals in the upper soil profile. Upon environmental and land-use changes, stable soil C is subject to losses, which influence the global C cycle and the productivity of terrestrial ecosystems. However, mechanisms controlling soil C destabilization are not...

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...

Causes and consequences of uncertainty in the application of a biogeochemical model to a large geographic region

Creator:: Kennedy, Robert Emmet, 1970-
Abstract:: When biogeochemical models are applied to large regions, the values of key model parameters are often unknowable. Through field and modeling studies, I examined the potential impact of such uncertainty on estimates of carbon cycling in western Oregon. I found that variation in key leaf traits could be interpreted ecologically,...

Measuring costs of sequestering carbon in forest stands with different management regimes in western Oregon

Creator:: Zyrina, Olga A.
Abstract:: This project was a part of larger work that compared major factors controlling patterns of carbon dynamics in two regions of the globe, the Pacific Northwest, USA and northwestern Russia. It was funded through the NASA foundation (grant # NAG5- 6242). Human economic activity is causing the release of pollutants...

Conifer : a model of carbon and water flow through a coniferous forest : revised documentation

Creator:: Sollins, P., Brown, Alfred T., Swartzman, G. L. (Gordon L.), and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: CONIFER simulates water, carbon, and energy dynamics of a coniferous forest. The model consists of 29 nonlinear difference equations. Measured driving variables include air temperature, dew point temperature, precipitation, solar radiation, and wind speed. Water and energy variables are updated daily; carbon variables are updated weekly. This report contains a...

Carbon dynamics in the hyporheic zone of a headwater mountain stream in the Cascade Mountains, Oregon

Creator:: Corson-Rikert, Hayley A.
Abstract:: This study investigated carbon dynamics in the hyporheic zone of a steep, forested catchment in the Cascade Mountains of western Oregon, USA. Water samples were collected monthly from a headwater stream and well network during baseflow conditions from July to December 2013 and again in March 2014. We also sampled...

Structural and physiological changes with stand age : use of a process-based model to compare carbon and water fluxes in young and old-growth Douglas-fir/western hemlock forest stands

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...

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...
