The idiosyncrasies of place: geographic variation in the climate–distribution relationships of the American pika

Creator:: Jeffress, Mackenzie R., Rodhouse, Thomas J., Ray, Chris, Wolff, Susan, and Epps, Clinton W.
Abstract:: Although climate acts as a fundamental constraint on the distribution of organisms, understanding how this relationship between climate and distribution varies over a species’ range is critical for addressing the potential impacts of accelerated climate change on biodiversity. Bioclimatic niche models provide compelling evidence that many species will experience range...

Identification of optimal broodstock for Pacific Northwest oysters

Creator:: Stick, David A.
Abstract:: The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...

Toxicity of pulp mill wastes to selected marine organisms and the characterization of the biological communities in the vicinity of a proposed ocean outfall for pulp mill wastes at Coos Bay, Oregon.

Creator:: Caldwell, Richard S., Oregon State University. Agricultural Experiment Station, and Oregon State University. Department of Fisheries and Wildlife
Abstract:: This report summarizes a study which sought to provide toxicity data for pulp mills near Coos Bay through a series of toxicity bioassays. The study also surveyed benthic and beach fauna to identify macro-organisms so individual assessments of water quality requirements could be made.

Ecological Effects of Tide Gate Upgrade or Removal: A Literature Review and Knowledge Synthesis - Final report

Creator:: Giannico, Guillermo, Souder, Jon, Tomaro, Londi, and Behan, Jeff
Abstract:: This document reports on findings, conclusions and recommendations derived from scientific literature and knowledge regarding the effectiveness of tide gate removal or upgrade in improving conditions for Oregon’s native migratory fish species, particularly salmonids, and other plant and animal species that utilize estuarine ecosystems. The project was commissioned by the...

Improving Projections of Tidal Marsh Persistence under Climate Change with Remote Sensing and Site-Specific Data

Creator:: Buffington, Kevin J.
Abstract:: Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with...

Redd site selection and spawning habitat use by fall chinook salmon

Creator:: Geist, David R.
Abstract:: The spawning habitat associated with fall chinook salmon (Oncorhynchus tshawytscha) redd clusters was investigated in the Hanford Reach of the Columbia River. A conceptual spawning habitat model is proposed that describes how geomorphic features of river channels create hydraulic processes, including hyporheic flows, that influence where salmon spawn in unconstrained...

Evaluating the Efficacy of Predicting Bycatch Mortality Using Reflex Impairment through an Assessment of Crab Discards

Creator:: Yochum, Noëlle
Abstract:: All animals that interact with fishing gear are not necessarily captured, and all animals that are captured are not necessarily retained. Fishing practices and gear configuration, management regulations, and markets dictate which animals ultimately are retained or discarded. The impact of a fishery and the efficacy of management regulations can...

Multiscale relationships of wintering birds with riparian and wetland habitat in the Willamette Valley, Oregon

Creator:: Adamus, Paul R.
Abstract:: Relatively little is known about wintering bird communities in lowlands of the Pacific Northwest, yet, the condition of winter habitats potentially can pose a major constraint on bird populations. I initiated a study to determine: (1) Which avian species use lowland riparian and wetland habitats in the Willamette Valley during...

California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...

A Meta-Analysis of Lesser Prairie-Chicken Nesting and Brood-Rearing Habitats: Implications for Habitat Management

Creator:: Hagen, Christian A., Grisham, Blacke A., Boal, Clint W., and Haukos, David A.
Abstract:: The distribution and range of lesser prairie-chicken (Tympanuchus pallidicinctus) has been reduced by >90% since European settlement of the Great Plains of North America. Currently, lesser prairie-chickens occupy 3 general vegetation communities: sand sagebrush (Artemisia filifolia), sand shinnery oak (Quercus havardii), and mixed-grass prairies juxtaposed with Conservation Reserve Program grasslands....
