Tropical origins of North and South Pacific decadal variability

Creator:: Shakun, Jeremy D. and Shaman, Jeffrey
Abstract:: The origin of the Pacific Decadal Oscillation (PDO), the leading mode of sea surface temperature variability for the North Pacific, is a matter of considerable debate. One paradigm views the PDO as an independent mode centered in the North Pacific, while another regards it as a largely reddened response to...

What drives interaction strengths in complex food webs? A test with feeding rates of a generalist stream predator

Creator:: Preston, Daniel L., Henderson, Jeremy S., Falke, Landon P., Segui, Leah M., Layden, Tamara J., and Novak, Mark
Abstract:: Describing the mechanisms that drive variation in species interaction strengths is central to understanding, predicting, and managing community dynamics. Multiple factors have been linked to trophic interaction strength variation, including species densities, species traits, and abiotic factors. Yet most empirical tests of the relative roles of multiple mechanisms that drive...

Performance of a combined organic Rankine cycle and vapor compression cycle for heat activated cooling

Creator:: Wang, Hailei, Peterson, Richard, Harada, Kevin, Miller, Erik, Ingram-Goble, Robbie, Fisher, Luke, Yih, James, and Ward, Chris
Abstract:: Heat activated cooling has the potential of utilizing thermal sources that currently go unused such as engine exhaust heat or industrial waste heat. Using these heat sources can provide enhanced energy utilization and reduced fuel usage in applications where cooling is needed. The concept developed here uses waste heat from...

Translocating Adult Pacific Lamprey within the Columbia River Basin: State of the Science

Creator:: Ward, David L., Clemens, Benjamin J., Clugston, David, Jackson, Aaron D., Moser, Mary L., Peery, Chris, and Statler, David P.
Abstract:: The Pacific lamprey (Entosphenus tridentatus) is in decline in the Columbia River Basin, and translocating adult lamprey to bypass difficult migration corridors has been implemented since 2000. We describe and report results from two current translocation programs, provide context for use of translocation, and discuss potential benefits, risks, and uncertainties....

Feeding performance by sympatric blue and fin whales exploiting a common prey resource

Creator:: Friedlaender, Ari S., Goldbogen, Jeremy A., Hazen, Elliott L., Calambokidis, John, and Southall, Brandon L.
Abstract:: A major focus in macroecology is to understand the mechanisms that drive differences in habitat, morphology, and behavior in closely related species (Brown 1995). Within this paradigm, energy use and prey acquisition play a fundamental role in affecting behavior, especially with respect to foraging patterns and predator‐prey interactions. Because resources...

The genetics of divergence and reproductive isolation between ecotypes of Panicum hallii

Creator:: Lowry, David B., Hernandez, Kyle, Taylor, Samuel H., Meyer, Eli, Logan, Tierney L., Barry, Kerrie W., Chapman, Jarrod A., Rokhsar, Daniel S., Schmutz, Jeremy, and Juenger, Thomas E.
Abstract:: The process of plant speciation often involves the evolution of divergent ecotypes in response to differences in soil water availability between habitats. While the same set of traits is frequently associated with xeric/mesic ecotype divergence, it is unknown whether those traits evolve independently or if they evolve in tandem as...

Nature for whom? How type of beneficiary influences the effectiveness of conservation outreach messages

Creator:: Batavia, Chelsea, Bruskotter, Jeremy T., Jones, Julia A., Vucetich, John A., Gosnell, Hannah, and Nelson, Michael Paul
Abstract:: In recent years the conservation community has engaged in debate over value in nonhuman nature, especially as it relates to motivations for conservation. Many have expressed the assumption that more people are willing to support conservation when emphasis is placed on the human benefits of nonhuman nature, rather than the...

Multiple-stage decisions in a marine central-place forager

Creator:: Friedlaender, Ari S., Johnston, David W., Tyson, Reny B., Kaltenberg, Amanda, Goldbogen, Jeremy A., Stimpert, Alison K., Curtice, Corrie, Hazen, Elliott L., Halpin, Patrick N., Read, Andrew J., and Nowacek, Douglas P.
Abstract:: Air-breathing marine animals face a complex set of physical challenges associated with diving that affect the decisions of how to optimize feeding. Baleen whales (Mysticeti) have evolved bulk-filter feeding mechanisms to efficiently feed on dense prey patches. Baleen whales are central place foragers where oxygen at the surface represents the...

Nano-scale investigation of the association of microbial nitrogen residues with iron (hydr)oxides in a forest soil O-horizon

Creator:: Keiluweit, Marco, Bougoure, Jeremy J., Zeglin, Lydia H., Myrold, David D., Weber, Peter K., Pett-Ridge, Jennifer, Kleber, Markus, and Nico, Peter S.
Abstract:: Amino sugars in fungal cell walls (such as chitin) represent an important source of nitrogen (N) in many forest soil ecosystems. Despite the importance of this material in soil nitrogen cycling, comparatively little is known about abiotic and biotic controls on and the timescale of its turnover. Part of the...

Estimates of Chinook salmon consumption in Washington State inland waters by four marine mammal predators from 1970 to 2015

Creator:: Chasco, Brandon E., Kaplan, Isaac C., Thomas, Austen C., Acevedo-Gutiérrez, Alejandro, Noren, Dawn P., Ford, Michael J., Hanson, M. Bradley, Scordino, Jonathan J., Jeffries, Steven J., Pearson, Scott, Marshall, Kristin N., and Ward, Eric J.
Abstract:: Conflicts can arise when the recovery of one protected species limits the recovery of another through competition or predation. The recovery of many marine mammal populations on the west coast of the United States has been viewed as a success; however, within Puget Sound in Washington State, the increased abundance...
