Asymmetrical effects of mesophyll conductance on fundamental photosynthetic parameters and their relationships estimated from leaf gas exchange measurements

Creator:: Sun, Ying, Gu, Lianhong, Dickinson, Robert E., Pallardy, Stephen G., Baker, John, Cao, Yonghui, Murilo DaMatta, Fábio, Dong, Xuejun, Ellsworth, David, Van Goethem, Davina, Jensen, Anna M., Law, Beverly E., Loos, Rodolfo, Vitor Martins, Samuel C., Norby, Richard J., Warren, Jeffrey, Weston, David, and Winter, Klaus
Abstract:: Worldwide measurements of nearly 130C3 species covering all major plant functional types are analysed in conjunction with model simulations to determine the effects of mesophyll conductance (gm) on photosynthetic parameters and their relationships estimated from A/Ci curves. We find that an assumption of infinite gm results in up to 75%...

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...

Evaluating theories of drought-induced vegetation mortality using a multimodel– experiment framework

Creator:: McDowell, Nate G., Gehres, Nathan, Limousin, Jean Marc, Macalady, Alison, Martínez-Vilalta, Jordi, Mencuccini, Maurizio, Plaut, Jennifer A., Ogée, Jérôme, Robert E., Pangle, Rasse, Daniel P., Ryan, Michael G., Fisher, Rosie A., Sevanto, Sanna, Waring, Richard H., Williams, A. Park, Yepez, Enrico A., Pockman, William T., Xu, Chonggang, Domec, Jean-Christophe, Holtta, Teemu, Mackay, D. Scott, Sperry, John S., Boutz, Amanda, and Dickman, Lee
Abstract:: Model–data comparisons of plant physiological processes provide an understanding of mechanisms underlying vegetation responses to climate. We simulated the physiology of a pi~non pine–juniper woodland (Pinus edulis–Juniperus monosperma) that experienced mortality during a 5 yr precipitation-reduction experiment, allowing a framework with which to examine our knowledge of drought-induced tree mortality....

Short-term response of Dicamptodon tenebrosus larvae to timber management in southwestern Oregon

Creator:: Leuthold, Niels, Adams, Michael J., and Hayes, John P.
Abstract:: In the Pacific Northwest, previous studies have found a negative effect of timber management on the abundance of stream amphibians, but results have been variable and region specific. These studies have generally used survey methods that did not account for differences in capture probability and focused on stands that were...

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...

Do network relationships matter? Comparing network and instream habitat variables to explain densities of juvenile coho salmon (Oncorhynchus kisutch) in mid-coastal Oregon, USA

Creator:: Flitcroft, Rebecca L., Burnett, Kelly M., Reeves, Gordon H., and Ganio, Lisa M.
Abstract:: 1. Aquatic ecologists are working to develop theory and techniques for analysis of dynamic stream processes and communities of organisms. Such work is critical for the development of conservation plans that are relevant at the scale of entire ecosystems. The stream network is the foundation upon which stream systems are...

An Illustrated Guide to Fire in Central Oregon Forests

Creator:: Eckert, Bradley E., Walstad, John D., and Tappeiner, J. C. (John C.)
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...

A numerical study of the transverse modulus of wood as a function of grain orientation and properties

Creator:: Nairn, John A.
Abstract:: Finite element analysis was used to study the effective transverse modulus of solid wood for all possible end-grain patterns. The calculations accounted for cylindrical anisotropy of wood within rectangular specimens and explicitly modeled wood as a composite of earlywood and latewood. The effective modulus was significantly reduced by growth ring...

Exploring the Relationship Between Human Disturbance and Wildlife Behavior in Protected Areas

Creator:: St. John, Alyssa
Abstract:: Wildlife behavior is a common research topic in conservation studies; however, the relationship between wildlife behavior and human disturbance, specifically in protected areas, is seldom studied. Previous studies have identified relationships between various different types of behaviors of both humans and wildlife, indicating correlations between avoidance behaviors, habituation, and physiological...
