Testing the metabolic theory of ecology

Creator:: Price, Charles A., Weitz, Joshua S., Savage, Van M., Stegen, James, Clarke, Andrew, Coomes, David A., Dodds, Peter S., Etienne, Rampal S., Kerkhoff, Andrew J., McCulloh, Katherine, Niklas, Karl J., Olff, Han, and Swenson, Nathan G.
Abstract:: The metabolic theory of ecology (MTE) predicts the effects of body size and temperature on metabolism through considerations of vascular distribution networks and biochemical kinetics. MTE has also been extended to characterise processes from cellular to global levels. MTE has generated both enthusiasm and controversy across a broad range of...

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...

Observations and assessment of forest carbon dynamics following disturbance in North America

Creator:: Goetz, S. J., Bond-Lamberty, B., Law, B. E., Hicke, J. A., Huang, C., Houghton, R. A., McNulty, S., O'Halloran, T., Harmon, M., Meddens, A. J. H., Pfeifer, E. M., Mildrexler, D., and Kasischke, E. S.
Abstract:: Disturbance processes of various types substantially modify ecosystem carbon dynamics both temporally and spatially, and constitute a fundamental part of larger landscape-level dynamics. Forests typically lose carbon for several years to several decades following severe disturbance, but our understanding of the duration and dynamics of post-disturbance forest carbon fluxes remains...

Genome resequencing reveals multiscale geographic structure and extensive linkage disequilibrium in the forest tree Populus trichocarpa

Creator:: Slavov, Gancho T., DiFazio, Stephen P., Martin, Joel, Schackwitz, Wendy, Muchero, Wellington, Rodgers-Melnick, Eli, Lipphardt, Mindie F., Pennacchio, Christa P., Hellsten, Uffe, Pennacchio, Len A., Gunter, Lee E., Ranjan, Priya, Vining, Kelly, Pomraning, Kyle R., Wilhelm, Larry J., Pellegrini, Matteo, Mockler, Todd C., Freitag, Michael, Geraldes, Armando, El-Kassaby, Yousry A., Mansfield, Shawn D., Cronk, Quentin C. B., Douglas, Carl J., Strauss, Steven H., Rokhsar, Dan, and Tuskan, Gerald A.
Abstract:: •Plant population genomics informs evolutionary biology, breeding, conservation and bioenergy feedstock development. For example, the detection of reliable phenotype–genotype associations and molecular signatures of selection requires a detailed knowledge about genome-wide patterns of allele frequency variation, linkage disequilibrium and recombination. •We resequenced 16 genomes of the model tree Populus trichocarpa...

Fire exclusion effects on riparian forest dynamics in southwestern Oregon

Creator:: Messier, Michael S., Shatford, Jeff P.A., and Hibbs, David E.
Abstract:: Euro-American settlement and organized fire suppression have been associated with structural and compositional changes in many upland forests of the western United States, but little is known about the impacts on riparian forests, portions of the landscape protected for habitat and water quality. In this study, we used dendro-ecological methods...

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...

Can fuel-reduction treatments really increase forest carbon storage in the western US by reducing future fire emissions?

Creator:: Campbell, John L., Harmon, Mark E., and Mitchell, Stephen R.
Abstract:: It has been suggested that thinning trees and other fuel-reduction practices aimed at reducing the probability of high-severity forest fire are consistent with efforts to keep carbon (C) sequestered in terrestrial pools, and that such practices should therefore be rewarded rather than penalized in C-accounting schemes. By evaluating how fuel...

Assessing the Carbon Consequences of Western Juniper (Juniperus occidentalis) Encroachment Across Oregon, USA

Creator:: Campbell, John L., Kennedy, Robert E., Cohen, Warren B., and Miller, Richard F.
Abstract:: Our ability to assess the continental impacts of woody encroachment remains compromised by the paucity of studies quantifying regional encroachment rates. This knowledge gap is especially apparent when it comes to quantifying the impact of woody encroachment on large-scale carbon dynamics. In this study, we use a combination of aerial...

An Illustrated Guide to Fire in Central Oregon Forests

Creator:: Eckert, Bradley E., Walstad, John D., and Tappeiner, John C., II
Abstract:: This pictorial guide is primarily intended to serve as a backdrop for field tours of central Oregon that involve topics surrounding wildland fire. It also is designed to provide an overview of the role of fire in the major ecosystems characteristic of this region. Topics covered include fire history, fire...

Does wildfire likelihood increase following insect outbreaks in conifer forests?

Creator:: Meigs, Garrett W., Campbell, John L., Zald, Harold S. J., Bailey, John D., Shaw, David C., and Kennedy, Robert E.
Abstract:: Although there is acute concern that insect-caused tree mortality increases the likelihood or severity of subsequent wildfire, previous studies have been mixed, with findings typically based on stand-scale simulations or individual events. This study investigates landscape- and regional-scale wildfire likelihood following outbreaks of the two most prevalent native insect pests...
