Little Ice Age climate and oceanic conditions of the Ross Sea, Antarctica from a coastal ice core record

Creator:: Rhodes, R. H., Bertler, N. A. N., Baker, J. A., Steen-Larsen, H. C., Sneed, S. B., Morgenstern, U., and Johnsen, S. J.
Abstract:: Increasing paleoclimatic evidence suggests that the Little Ice Age (LIA) was a global climate change event. Understanding the forcings and associated climate system feedbacks of the LIA is made difficult by the scarcity of Southern Hemisphere paleoclimate records. We use a new glaciochemical record of a coastal ice core from...

Use of change-point detection for friction–velocity threshold evaluation in eddy-covariance studies

Creator:: Barr, A. G., Richardson, A. D., Hollinger, D. Y., Papale, D., Arain, M. A., Black, T. A., Bohrer, G., Dragoni, D., Fischer, M. L., Gu, L., Law, B. E., Margolis, H. A., McCaughey, J. H., Munger, J. W., Oechel, W., and Schaeffer, K.
Abstract:: The eddy-covariance method often underestimates fluxes under stable, low-wind conditions at night when turbulence is not well developed. The most common approach to resolve the problem of nighttime flux underestimation is to identify and remove the deficit periods using friction-velocity (u*) threshold filters (u*[superscript Th]). This study modifies an accepted...

Toward biologically meaningful net carbon exchange estimates for tall, dense canopies: Multi-level eddy covariance observations and canopy coupling regimes in a mature Douglas-fir forest in Oregon

Creator:: Thomas, Christoph K., Martin, Jonathan G., Law, Beverly E., and Davis, Kent
Abstract:: We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...

Survival and growth patterns of white spruce (Picea glauca [Moench] Voss) rangewide provenances and their implications for climate change adaptation

Creator:: Lu, Pengxin, Parker, William H., Cherry, Marilyn, Colombo, Steve, Parker, William C., Man, Rongzhou, and Roubal, Ngaire
Abstract:: Intraspecific assisted migration (ISAM) through seed transfer during artificial forest regeneration has been suggested as an adaptation strategy to enhance forest resilience and productivity under future climate. In this study, we assessed the risks and benefits of ISAM in white spruce based on long-term and multilocation, rangewide provenance test data....

Potentials and limitations for estimating daytime ecosystem respiration by combining tower-based remote sensing and carbon flux measurements

Creator:: Hilker, Thomas, Hall, Forrest G., Coops, Nicholas C., Black, Andrew T., Jassal, Rachhpal, Mathys, Amanda, and Grant, Nicholas
Abstract:: Vegetation carbon uptake and respiration constitute the largest carbon cycle of the planet with an annual turnover in the order of 120 GT. Currently, neither ecosystem carbon uptake (through photosynthesis) nor ecosystem carbon release (through respiration) can be measured directly during the daytime. Instead, flux-tower measurements rely on nighttime respiration...

Genome sequence of a white rot fungus Schizopora paradoxa KUC8140 for wood decay and mycoremediation

Creator:: Min, Byoungnam, Park, Hongjae, Jang, Yeongseon, Kim, Jae-Jin, Kim, Kyoung Heon, Pangilinan, Jasmyn, Lipzen, Anna, Riley, Robert, Grigoriev, Igor V., Spatafora, Joseph W., and Choi, In-Geol
Abstract:: Schizopora paradoxa KUC8140 is a white rot wood degrader commonly found in Korea. Tolerance to heavy metals and polycyclic aromatic hydrocarbons and dye decolorization activity make this strain a potential candidate for mycoremediation. We report the genome sequence of S. paradoxa KUC8140 containing 44.4 Mbp. Based on ab initio gene...

Remote sensing of transpiration and heat fluxes using multi-angle observations

Creator:: Hilker, Thomas, Hall, Forrest G., Coops, Nicholas C., Collatz, James G., Black, T. Andrew, Tucker, Compton J., Sellers, Piers J., and Grant, Nicholas
Abstract:: Surface energy balance is a major determinant of land surface temperature and the Earth's climate. To date, there is no approach that can produce effective, physically consistent, global and multi-decadal energy–water flux data over land. Net radiation (R[subscript n]) can be quantified regionally using satellite retrievals of surface reflectance and...

Technical change and pollution abatement costs

Creator:: Färe, Rolf, Grosskopf, Shawna, and Pasurka, Carl
Abstract:: There is continuing interest in the trend of costs associated with pollution abatement activities. We specify an environmental production technology to model the joint production of good and bad outputs. The joint production model calculates pollution abatement costs and identifies changes in these costs associated with: (1) technical change, (2)...

Abstract:: Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...

Five years of carbon fluxes and inherent water-use efficiency at two semi-arid pine forests with different disturbance histories

Creator:: Vickers, Dean, Thomas, Christoph K., Pettijohn, Cory, Martin, Jon G., and Law, Beverly E.
Abstract:: Five years of eddy-covariance and other measurements at a mature ponderosa pine forest and a nearby young plantation are used to contrast the carbon fluxes for long-term averages, seasonal patterns, diel patterns and interannual variability, and to examine the differing responses to water-stress. The mature forest with larger leaf area...
