Identifying "at-risk" regions of snow accumulation within California's Sierra Nevada Mountains, and assessing implications on reservoir operations

Creator:: Kalyan, Imtiaz-Ali M.
Abstract:: California's water resources vary throughout the state owing to the regions varying topography, diverse climate, and the distribution of precipitation. Most of the state's precipitation falls over the northern coastal range and the western slopes of the Sierra Nevada Mountains. Winter snowpack that accumulates within these mountain basins serves as...

Multiscale assessment of thermal patterns and the distribution of chinook salmon in the John Day River Basin, Oregon

Creator:: Torgersen, Christian E.
Abstract:: This study examined the distribution and behavior of adult spring chinook salmon (Oncorhynchus tshawytscha) related to patterns of stream temperature and physical habitat at channel unit, reach, and basin-wide spatial scales in both a wilderness stream and a disturbed stream in the John Day River basin in northeastern Oregon. Thermal...

Distribution and habitat use of bull trout following the removal of nonnative brook trout

Creator:: Renner, Dirk
Abstract:: Invasion by nonnative brook trout (Salvelinus fontinalis) often results in replacement of bull trout (Salvelinus confluentus) in western North America, but the causal mechanisms are not well understood. Removal of brook trout from 1992 to 2000 from Sun Creek in southern Oregon, provided an opportunity to investigate the changes in...

Historical fire regime in the Little River watershed, southwestern Oregon

Creator:: Van Norman, Kelli J.
Abstract:: Disturbances are a prevalent and important part of ecosystems. Many landscape patterns that we find today were created, maintained, and changed by natural disturbance regimes. This is especially true for fire, which has historically been a common, natural disturbance in the western U.S forests and grasslands and many other parts...

Isotopic composition of respired CO2 in a small watershed : development and testing of an automated sampling system and analysis of first year data

Creator:: Hauck, Mark J.
Abstract:: Warming of the terrestrial biosphere due to the anthropogenic addition of carbon dioxide to the earth’s atmosphere is becoming a major focus of scientific inquiry. Predictions of the extent of this warming are hampered by uncertainty in the ability of the earth’s ecosystems to counteract this effect by sequestering carbon...

Spatio-temporal Patterns and Ecological Drivers of Harbor Porpoise (Phocoena phocoena) off the Central Oregon Coast, USA

Creator:: Holdman, Amanda
Abstract:: The marine environment is under increasing pressure from human activities worldwide, particularly in coastal waters, creating a need to better understand fine-scale distributions of highly mobile species that occur in the area, as they are frequently most threatened. Harbor porpoise (Phocoena phocoena) occur frequently in Oregon’s nearshore habitat, but due...

Massive MIMO Channel Characterization

Creator:: Assiri, Mohammad
Abstract:: It has been estimated that data traffic from the different mobile devices that range from smartphones to machine-to-machine (M2M) devices will exceed 15.9 exabyte per month by the year 2018. With this immense data growth, the current wireless communication systems suffer from the scarcity of the radio spectrum and eventually...

Foraging Niche Separation of Adélie (Pygoscelis adeliae) and Gentoo (P. papua) Penguins During the Breeding Season at Palmer Station, Antarctica

Creator:: Pickett, Erin
Abstract:: Climate-induced range overlap can result in novel interactions between similar species and potentially lead to competitive exclusion. The Western Antarctic Peninsula is one of the most rapidly warming regions on Earth and is experiencing a poleward climate migration. This transition from a polar to sub-polar environment has resulted in a...

Rivers and Roads : Exploring How Environmental Governance Impacts State Management of Forest Roads

Creator:: Detwiler, Stacey M.
Abstract:: This study explores how environmental governance mechanisms affect state management of forest roads to address the chronic delivery of sediment to streams in Oregon, Washington, and California on private and state forestlands. Forest roads can degrade water quality and harm aquatic life when runoff mobilizes fine sediments from the road...

Monitoring Restoration in South Sister Creek : The Effect of Stream Enhancement Structures on Water Temperature

Creator:: Harewood, Alessandra Greer
Abstract:: This pilot study of South Sister Creek (8 km length) examined stream-scale (i.e., longitudinal trends) and sub-reach scale (less than 100 m) water temperature. Hourly summer temperature time-series data were gathered at four to seven locations along South Sister Creek in 2006, 2012, and 2013 and were used to explore...
