Investigating Calving Areas for Rocky Mountain Elk on the Plumas National Forest: Implications for Land Management

Creator:: Marshall, Abigail C.
Abstract:: Sustainable elk (Cervus canadensis) habitat management on U.S. Forest Service (USFS) lands involves a complex relationship between management practices and ecological processes. A relatively novel Rocky Mountain elk population (Cervus canadensis nelsoni) on the Plumas National Forest (PNF) in northeastern California became established in the early 2000s, but there is...

Headwater Streams and Wetlands are Critical for Sustaining Fish, Fisheries, and Ecosystem Services

Creator:: Colvin, Susan A. R., Sullivan, S. Mazeika P., Shirey, Patrick D., Colvin, Randall W., Winemiller, Kirk O., Hughes, Robert M., Fausch, Kurt D., Infante, Dana M., Olden, Julian D., Bestgen, Kevin R., Danehy, Robert J., and Eby, Lisa
Abstract:: Headwater streams and wetlands are integral components of watersheds that are critical for biodiversity, fisheries, ecosystem functions, natural resource-based economies, and human society and culture. These and other ecosystem services provided by intact and clean headwater streams and wetlands are critical for a sustainable future. Loss of legal protections for...

A doubled down invasion of the northeast Pacific by the Asian mud shrimp, Upogebia major and its coevolved bopyrid isopod parasite, Orthione griffenis

Creator:: Chapman, John W., Li, Jingchun, McGowan, Michael F., Breitenstein, Ralph A., Appy, Ralph, Hieb, Kathryn A., Piotrowski, Christina N., and Elder, Leanne E.
Abstract:: Dramatic declines of the native northeast Pacific mud shrimp, Upogebia pugettensis over the last three decades have occurred in response to intense infestations by the Asian bopyrid isopod parasite, Orthione griffenis, that was introduced in the 1980s. We report herein the arrival of the Asian mud shrimp, Upogebia major, in...

Banks, Gardens and Bees: Enhancing Community Resilience in West Africa

Creator:: Polasky, Sophia
Abstract:: International development programs are often implemented with the goal of building community resilience, but without a clear articulation of how this goal will be met, or any consideration of if or why the effort was successful after it has concluded. This thesis considers three different activities implemented by the U....

Effects of controlled atmosphere, edible coating, and 1-methylcyclopropene on improving storage quality of 'Bartlett' pears after long-term storage

Creator:: Zhi, Huanhuan, Dong, Yu, and Wang, Yan
Abstract:: Recent trends towards greater fresh market use of 'Bartlett' pears has increased the need to extend its storage life to prolong the packing and marketing season in the United States Pacific Northwest region. Sixteen and 38%, respectively, of control fruit developed senescence disorders following 5 and 6 months of storage...

Eocene Origin of Owens Valley, California

Creator:: Sousa, Francis J.
Abstract:: Bedrock (U-Th)/He data reveal an Eocene exhumation difference greater than four kilometers athwart Owens Valley, California near the Alabama Hills. This difference is localized at the eastern fault-bound edge of the valley between the Owens Valley Fault and the Inyo-White Mountains Fault. Time-temperature modeling of published data reveal a major...

Grazing Effects on Fuels and Plant Community Characteristics across Three Community Types in Wyoming Big Sagebrush Steppe

Creator:: Thomas, Tyler W.
Abstract:: Livestock grazing is the prominent land use in Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) steppe and has been present since the late 1800’s. There have been calls to remove livestock grazing from rangelands as historic grazing practices resulted in the degradation of some...

Spatial Patterns of Chemical Weathering at the Basal Tertiary Nonconformity in California from Multispectral and Hyperspectral Optical Remote Sensing

Creator:: Sousa, Francis J. and Sousa, Daniel J.
Abstract:: Visible through shortwave (VSWIR) spectral reflectance of the geologic units across the basal Tertiary nonconformity (BTN) is characterized at three spatially disparate locations in California. At two of these sites, location-specific spectral endmembers are obtained from AVIRIS imaging spectroscopy and linear spectral mixture models are used to visualize spatial patterns...

Resilience and resistance in sagebrush ecosystems are associated with seasonal soil temperature and water availability

Creator:: Roundy, Bruce A., Chambers, Jeanne C., Pyke, David A., Miller, Richard F., Tausch, Robin J., Schupp, Eugene W., Rau, Ben, and Gruell, Trevor
Abstract:: Invasion and dominance of exotic grasses and increased fire frequency threaten native ecosystems worldwide. In the Great Basin region of the western United States, woody and herbaceous fuel treatments are implemented to decrease the effects of wildfire and increase sagebrush (Artemisia spp.) ecosystem resilience to disturbance and resistance to exotic...
