Using GIS to illustrate the geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in Oregon

Creator:: Cohn, Leanne A.
Abstract:: There could be a geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in the United States. Marine renewable energy generation efforts are currently being planned, studied, and initially implemented in the country as a response to climate change. The Bureau of Ocean Energy Management is...

Grazer-resource Behavior, Interactions, and Feedbacks Control Kelp-forest Dynamics and Stability

Creator:: Randell, Zachary H.
Abstract:: How the direct and indirect effects of species interactions cascade to affect community structure, functioning, and stability is a fundamental question in ecology. In temperate kelp forests, species interactions, in conjunction with environmental processes, produce rich spatiotemporal dynamics. Arguably the most dramatic of these are abrupt shifts in community state,...

Range-use estimation and encounter probability for juvenile Steller sea lions (Eumetopias jubatus) in the Prince William Sound-Kenai Fjords region of Alaska

Creator:: Meck, Stephen R.
Abstract:: Range, areas of concentrated activity, and dispersal characteristics for juvenile Steller sea lions Eumetopias jubatus in the endangered western population (west of 144° W in the Gulf of Alaska) are poorly understood. This study quantified space use by analyzing post-release telemetric tracking data from satellite transmitters externally attached to n...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

Multi-Centennial Response of ENSO Under Varying Atmospheric CO2

Creator:: Alder, Jay R.
Abstract:: The El Niño/Southern Oscillation (ENSO) affects millions of people via global teleconnections in the form of drought and torrential rainfall that impact agriculture and food production in many countries. Yet how ENSO will respond to a warming world is uncertain and a greatly debated topic. The Intergovernmental Panel on Climate...

Assessing the Role of Snow Cover for Regenerating Forests over Post-wildfire Landscapes in the Pacific Northwest

Creator:: Wilson, Andy C.
Abstract:: Forested, mountain landscapes in the Pacific Northwest (PNW) are changing at an unprecedented rate, largely due to shifts in the regional climate regime. Documented climatic trends across the PNW include increasing wildfire frequency and intensity and an increasingly ephemeral snowpack, especially at moderate elevations. One relationship that has yet to...

The influence of biophysical feedbacks and species interactions on grass invasions and coastal dune morphology in the Pacific Northwest, USA

Creator:: Zarnetske, Phoebe Lehmann
Abstract:: Biological invasions provide a unique opportunity to study the mechanisms that regulate community composition and ecosystem function. Invasive species that are also ecosystem engineers can substantially alter physical features in an environment, and this can lead to cascading effects on the biological community. Aquatic-terrestrial interface ecosystems are excellent systems to...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

Non-native and native plant species distributions and variability along an elevation gradient in the Wallowa Mountains, Oregon

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...

Carnivore Competition: Spatial and Dietary Implications of Gray Wolf Recolonization for Cougars in Northeast Oregon

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)...
