Creator:: Shin, Eun Jung
Abstract:: A new high-throughput culturing (HTC) method using a low nutrient heterotrophic medium (LNHM) has led to the isolation of many novel strains of oligotrophic bacteria from marine ecosystems. Four strains belonging to a single dade, HTCC2151, HTCC218OT, HTCC2178T and HTCC2188T, were isolated from the coast of Oregon by the HTC...

Creator:: Rose, Kelly Kathleen
Abstract:: Despite more than two centuries of exploration, including more than six million deep wellbores with depths exceeding 40,000 feet in some parts of the world, our ability to constrain subsurface processes and properties remains limited. Characteristics of the subsurface vary and can be analyzed on a variety of spatial scales....

Creator:: Clark, Jessica S.
Abstract:: The assessment of habitat quality for wild populations requires evaluation of vital rates associated with the use of that habitat. Factors associated with bottom-up (forage) or top-down (predation) regulation and the relative contribution of these processes on ungulate populations are difficult to quantify, especially for a cryptic, but widely distributed...

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...

Creator:: Taylor, David S.
Abstract:: Ecology is focused on understanding how organisms interact with each other and their environments, across ecological, spatial, and temporal scales. Thus, understanding how processes and patterns of ecological systems change across space and time is a principle goal for conservation biologist globally. While many approaches exist for investigating the changing...

Creator:: Averett, Joshua P.
Abstract:: Invasion by non-native plants into natural areas is an important component of global change that threatens biodiversity and ecosystem structure and function. Mountains are currently among the least invaded ecosystems, however, these biodiversity hotspots are increasingly under threat of exotic plant invasion. Evaluation of plant species distribution patterns in mountain...

Creator:: Orning, Elizabeth Kari
Abstract:: After a 40-year absence from Oregon’s landscape, expanding gray wolf (Canis lupus) populations are reestablishing elements of interspecific competition with sympatric large carnivores, like cougars (Puma concolor). This presents new challenges for management of large carnivores and their ungulate prey populations (e.g., elk, Cervus canadensis nelsoni; mule deer, Odocoileus hemionus)...
