Dust, volcanic ash, and the evolution of the South Pacific Gyre through the Cenozoic

Creator:: Dunlea, Ann G., Murray, Richard W., Sauvage, Justine, Spivack, Arthur J., Harris, Robert N., and D'Hondt, Steven
Abstract:: We examine the 0–100 Ma paleoceanographic record retained in pelagic clay from the South Pacific Gyre (SPG) by analyzing 47 major, trace, and rare earth elements in bulk sediment in 206 samples from seven sites drilled during Integrated Ocean Drilling Program Expedition 329. We use multivariate statistical analyses (Q-mode factor analysis...

Quantifying Bulk Electrode Strain and Material Displacement within Lithium Batteries via High-Speed Operando Tomography and Digital Volume Correlation

Creator:: Finegan, Donal P., Tudisco, Erika, Scheel, Mario, Robinson, James B., Taiwo, Oluwadamilola O., Eastwood, David S., Lee, Peter D., Di Michiel, Marco, Bay, Brian, Hall, Stephen A., Hinds, Gareth, Brett, Dan J. L., and Shearing, Paul R.
Abstract:: Tracking the dynamic morphology of active materials during operation of lithium batteries is essential for identifying causes of performance loss. Digital volume correlation (DVC) is applied to high-speed operando synchrotron X-ray computed tomography of a commercial Li/MnO₂ primary battery during discharge. Real-time electrode material displacement is captured in 3D allowing...

Coastal protection and conservation on sandy beaches and dunes : Context-dependent tradeoffs in ecosystem service supply

Creator:: Ruggiero, Peter, Seabloom, Eric W., Hacker, Sally D., Biel, Reuben G., and Cohn, Nicholas
Abstract:: Managing multiple ecosystem services (ESs) across landscapes presents a central challenge for ecosystem-based management, because services often exhibit spatiotemporal variation and weak associations with co-occurring ESs. Further focus on the mechanistic relationships among ESs and their underlying biophysical processes provides greater insight into the causes of variation and covariation among...

Multivariate Vegetation Mapping -- Code and Data

Creator:: Henderson, Emilie B.
Abstract:: This data set contains RCode designed for mapping correlated vegetation summary variables via univariate (modified random forest regression) and multivariate (random forest nearest neighbor) methods. It also contains a small vegetation plot dataset to illustrate the type of information needed to support such an analysis.

Diet overlap by DNA metabarcoding of mule deer, elk, and cattle in ponderosa pine forest of eastern Oregon

Creator:: Faber, M. Kate
Abstract:: Millions of acres of rangeland in the western U.S. is shared habitat by elk (Cervus canadensis), mule deer (Odocoileus hemionus), and cattle (Bos taurus). Potential competition between these ungulates for the same forage species can be understood from their diet composition. I used DNA metabarcoding methods with trnL primers to...

Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...

Variation of the Trowbridge's shrew (Sorex trowbridgii) diet across forest types in the Oregon Cascades

Creator:: Yates, Margaret E.
Abstract:: Investigating the insectivorous diet of the Trowbridge’s shrew (Sorex trowbridgii) across forest types can illustrate how forest management affects biotic communities. I used DNA metabarcoding methods with ANML primers to identify stomach and intestines contents from shrews caught in pitfall traps in the HJ Andrews Experimental Forest (HJA) and Willamette...

Populations of aspen (Populus tremuloides Michx.) with different evolutionary histories differ in their climate occupancy

Creator:: Greer, Burke T., Still, Christopher, Howe, Glenn T., Tague, Christina, and Roberts, Dar A.
Abstract:: Quaking aspens (Populus tremuloides Michx.) are found in diverse habitats throughout North America. While the biogeography of aspens' distribution has been documented, the drivers of the phenotypic diversity of aspen are still being explored. In our study, we examined differences in climate between northern and southwestern populations of aspen, finding...

Integrating occupancy models and structural equation models to understand species occurrence

Creator:: Joseph, Maxwell B., Preston, Daniel Lucas, and Johnson, Pieter T. J.
Abstract:: Understanding the drivers of species occurrence is a fundamental goal in basic and applied ecology. Occupancy models have emerged as a popular approach for inferring species occurrence because they account for problems associated with imperfect detection in field surveys. Current models, however, are limited because they assume covariates are independent...
