Carbon stocks and accumulation rates in Pacific Northwest forests: role of stand age, plant community, and productivity

Creator:: Gray, Andrew N., Whittier, Thomas R., and Harmon, Mark E.
Abstract:: Forest ecosystems are removing significant amounts of carbon from the atmosphere. Both abiotic resource availability and biotic interactions during forest succession affect C accumulation rates and maximum C stocks. However, the timing and controls on the peak and decline in C accumulation rates as stands age, trees increase in size,...

Public lands and private waters: scarce mesic resources structure land tenure and sage-grouse distributions

Creator:: Donnelly, J. P., Naugle, D. E., Hagen, C. A., and Maestas, J. D.
Abstract:: Water scarcity in semiarid environments provides a model system to evaluate the role of mesic resources in structuring the distribution and abundance of wildlife. We used remote sensing and point process analyses to evaluate spatio–temporal variability in limited mesic resources in relation to greater sage-grouse (Centrocercus urophasianus) distributions in Oregon,...

The conservation genetics juggling act: integrating genetics and ecology, science and policy

Creator:: Haig, Susan M., Miller, Mark. P., Bellinger, Renee, Draheim, Hope M., Mercer, Dacey M., and Mullins, Thomas D.
Abstract:: The field of conservation genetics, when properly implemented, is a constant juggling act integrating molecular genetics, ecology, and demography with applied aspects concerning managing declining species or implementing conservation laws and policies. This young field has grown substantially since the 1980s following the development of polymerase chain reaction and now...

American pika in a low-elevation lava landscape: expanding the known distribution of a temperature-sensitive species

Creator:: Shinderman, Matt
Abstract:: In 2010, the American pika (Ochotona princeps fenisex) was denied federal protection based on limited evidence of persistence in low-elevation environments. Studies in nonalpine areas have been limited to relatively few environments, and it is unclear whether patterns observed elsewhere (e.g., Bodie, CA) represent other nonalpine habitats. This study was...

Ampelisca eschrichtii Krøyer, 1842 (Ampeliscidae) of the Sakhalin Shelf in the Okhotsk Sea starve in summer and feast in winter

Creator:: Durkina, Valentina B., Chapman, John W., and Demchenko, Natalia L.
Abstract:: Background. Ampelisca eschrichtii Krøyer, 1842 of the Sakhalin Shelf of the Okhotsk Sea, Far Eastern Russia, comprise the highest known biomass concentration of any amphipod population in the world and are a critically important prey source for western gray whales. Growth and reproduction in this population has not been apparent...

Life History and Production of the Western Gray Whale's Prey, Ampelisca eschrichtii Krøyer, 1842 (Amphipoda, Ampeliscidae)

Creator:: Demchenko, Natalia L., Chapman, John W., Durkina, Valentina B., and Fadeev, Valeriy I.
Abstract:: Ampelisca eschrichtii are among the most important prey of the Western North Pacific gray whales, Eschrichtius robustus. The largest and densest known populations of this amphipod occur in the gray whale’s Offshore feeding area on the Northeastern Sakhalin Island Shelf. The remote location, ice cover and stormy weather at the...

Endogenous Small RNA Mediates Meiotic Silencing of a Novel DNA Transposon

Creator:: Wang, Yizhou, Smith, Kristina M., Taylor, John W., Freitag, Michael, and Stajich, Jason E.
Abstract:: Genome defense likely evolved to curtail the spread of transposable elements and invading viruses. A combination of effective defense mechanisms has been shown to limit colonization of the Neurospora crassa genome by transposable elements. A novel DNA transposon named Sly1-1 was discovered in the genome of the most widely used...

Cutting performance comparison of low-kickback saw chain

Creator:: Otto, Andrew and Parmigiani, John P.
Abstract:: Kickback is the leading cause of the most severe and traumatic chainsaw-related injuries. As a result, safety standards require chainsaw manufacturers to produce low-kickback saw chain. In order to understand the tradeoffs in current state-of-the-art saw chain, a comparison study was conducted on a custom test apparatus using four different...

Spatial patterns and trends of summertime low cloudiness for the Pacific Northwest, 1996-2017

Creator:: Dye, Alex W., Rastogi, Bharat, Clemesha, Rachel E. S., Kim, John B., Samelson, Roger M., Still, Christopher J., and Williams, A. Park
Abstract:: Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...
