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...

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%...

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...

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...

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....

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...

Dataset associated with Long-Term Effects of Fuel Reduction Treatments on Surface Fuel Loading in the Blue Mountains of Oregon

Creator:: Morici, Kat
Abstract:: Dataset contains a 2015 partial re-measurement of the Blue Mountains Fire and Fire Surrogate study. 8 plots were measured from each of the 16 units, selected randomly from all plots in each unit. Species are recorded using USDA plant codes, "UNKN" is unknown species. For fine fuels, 3 Brown's transects...

The Northern Goshawk on the Southern Blue Mountains and Malheur National Forest: A Technical Review of its Status, Ecology and Management

Creator:: Goodell, John M. and Seager, S. Trent
Abstract:: Stakeholders in the southern Blue Mountains have reported a need for a scientific review of the northern goshawk (Accipiter gentilis atricapillus; hereafter, goshawk) in relation to dry forest restoration and management activities. Here, we provide a compilation of relevant synthesis papers, existing peer-reviewed research, and goshawk monitoring efforts in the...

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...

Generalized crack closure analysis for elements with arbitrarily-placed side nodes and consistent nodal forces

Creator:: Nairn, John A.
Abstract:: A new approach was developed for the evaluation of energy release rate by the virtual crack closure technique in quadratic and linear elements. The generalized method allows arbitrary placement of the side nodes for quadratic elements and thus includes both standard elements, with mid-side nodes, and singularity elements, with quarter-point...
