Environmental Relationships in Forests of Early 20th Century Coos County, Oregon, Based on Timber Cruise Data

Creator:: Zobel, Donald B.
Abstract:: Timber cruise data can provide useful information not available elsewhere. Measurements of timber volume (timber cruises) from the early 20th century for Coos County, Oregon, were used to assess the degree to which tree species distribution and timber volume varied with edaphic and climatic factors. The study area has diverse...

Impacts of Policy and Environmental Change: Understanding Factors of Vulnerability and Resilience in the Face of Change in Oregon Fishing Communities

Creator:: Strawn, Astrea
Abstract:: Commercial fisheries are coupled human-natural systems that cross state borders and integrate private, public, academic sectors and interests. These systems integrate complicated relationships between coastal socioeconomics, resource management and environmental realms. Previous findings from West Coast-based studies have identified aging trends in commercial fisheries participation, commonly referred to as the...

Drone Up! Quantifying Whale Behavior From a New Perspective Improves Observational Capacity

Creator:: Lemos, Leila, Chandler, Todd E., Torres, Leigh G., and Nieukirk, Sharon L.
Abstract:: During traditional boat-based surveys of marine megafauna, behavioral observations are typically limited to records of animal surfacings obtained from a horizontal perspective. Achieving an aerial perspective has been restricted to brief helicopter or airplane based observations that are costly, noisy, and risky. The emergence of commercial small unmanned aerial systems...

The Western Pacific barred knifejaw, Oplegnathus fasciatus (Temminck & Schlegel, 1844) (Pisces: Oplegnathidae), arriving with tsunami debris on the Pacific coast of North America

Creator:: Chapman, John W., Ta, Nicholas, Miller, Jessica A., Carlton, James T., Miller-Morgan, Timothy, Calvanese, Thomas, Pleus, Allen E., and Burke, James
Abstract:: The Western Pacific Ocean barred knifejaw Oplegnathus fasciatus was found from 2013 to 2015 along the Pacific Coast of North America from Washington to California. The knifejaw was found in derelict vessels that had arrived on the Pacific Coast and that had been lost during the March 2011 Great Japan...

Biological screening of selected Pacific Northwest forest plants using the brine shrimp (Artemia salina) toxicity bioassay

Creator:: Karchesy, Yvette M., Kelsey, Rick G., Constantine, George, and Karchesy, Joseph J.
Abstract:: The brine shrimp (Artemia salina) bioassay was used to screen 211 methanol extracts from 128 species of Pacific Northwest plants in search of general cytotoxic activity. Strong toxicity (LC₅₀ < 100 µg/ml) was found for 17 extracts from 13 species, with highest activity observed for Angelica arguta roots at <10...

A Case Study in the Role of Values in Discourse and Consensus in Pacific Northwest Forest Collaboratives

Creator:: Karnstein, Mackenzie R.
Abstract:: Collaborative governance plays a significant role in forest management on public land in the Pacific Northwest. The method of governance offers the unique ability to engage a diverse range of stakeholders to reach consensus regarding forest management action. Evaluating the dynamics of the collaborative and its members is essential to...

Proposal to Establish Ruchi Glades Research Natural Area

Creator:: Murray, Michael
Abstract:: Ruchi Glades is proposed for designation as a Research Natural Area. It is located on the upper slopes of Oregon Caves National Monument which is administered by the National Park Service. Ruchi Glads has an impressive diversity of plant communities for such a small area. The Oregon Natural Heritage Plan...

Coastal protection and conservation on sandy beaches and dunes : Context-dependent tradeoffs in ecosystem service supply

Creator:: Ruggiero, Peter, Seabloom, Eric W., Hacker, Sally D., Biel, Reuben G., and Cohn, Nicholas
Abstract:: Managing multiple ecosystem services (ESs) across landscapes presents a central challenge for ecosystem-based management, because services often exhibit spatiotemporal variation and weak associations with co-occurring ESs. Further focus on the mechanistic relationships among ESs and their underlying biophysical processes provides greater insight into the causes of variation and covariation among...

Assessment of fecal steroid and thyroid hormone metabolites in eastern North Pacific gray whales

Creator:: Lemos, Leila S., Olsen, Amy, Smith, Angela, Chandler, Todd E., Larson, Shawn, Hunt, Kathleen, and Torres, Leigh G.
Abstract:: Baleen whale fecal samples have high potential for endocrine monitoring, which can be used as a non-invasive tool to identify the physiological response to disturbance events and describe population health and vital rates. In this study, we used commercial enzyme-linked immunosorbent assays to validate and quantify fecal steroid (progestins, androgens...
