Natural-Channel-Design Restorations that Changed Geomorphology Have Little Effect on Macroinvertebrate Communities in Headwater Streams

Creator:: Ernst, Anne G., Warren, Dana R., and Baldigo, Barry P.
Abstract:: Stream restorations that increase geomorphic stability can improve habitat quality, which should benefit selected species and local aquatic ecosystems. This assumption is often used to define primary restoration goals; yet, biological responses to restoration are rarely monitored or evaluated methodically. Macroinvertebrate communities were inventoried at 6 study reaches within 5...

Distribution, habitat associations, and conservation status of Pacific fisher (Pekania pennanti) in Oregon.

Creator:: Barry, Brent R.
Abstract:: Fishers (Pekania pennanti) are medium sized mustelids endemic to North America. Two fisher populations persist in Oregon: an indigenous population in southwestern Oregon, and a reintroduced population in the southern Cascade Mountains. Despite candidacy for listing under the Endangered Species Act, current information on fisher populations in Oregon is scarce....

Migrational characteristics and survival rates of mallards banded at Malheur National Wildlife Refuge

Creator:: Furniss, Sean Barry
Abstract:: An analysis of 4,385 recoveries of mallards (Anas platyrhynchos), that were reported during the years 1929 to 1972, was made to determine the migrational characteristics and survival rates of mallards banded at Malheur National Wildlife Refuge in southeastern Oregon. Two populations, a transitory population and a wintering population, were banded...

Competitive interactions and resource partitioning between northern spotted owls and barred owls in western Oregon

Creator:: Wiens, J. David
Abstract:: The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...

Population and behavioral responses of small mammals to silviculture and downed wood treatments in the Oregon Coast Range

Creator:: Waldien, David L.
Abstract:: Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...

Estimates of Chinook salmon consumption in Washington State inland waters by four marine mammal predators from 1970 to 2015

Creator:: Chasco, Brandon E., Kaplan, Isaac C., Thomas, Austen C., Acevedo-Gutiérrez, Alejandro, Noren, Dawn P., Ford, Michael J., Hanson, M. Bradley, Scordino, Jonathan J., Jeffries, Steven J., Pearson, Scott, Marshall, Kristin N., and Ward, Eric J.
Abstract:: Conflicts can arise when the recovery of one protected species limits the recovery of another through competition or predation. The recovery of many marine mammal populations on the west coast of the United States has been viewed as a success; however, within Puget Sound in Washington State, the increased abundance...

eDNA as a tool for identifying freshwater species in sustainable forestry: A critical review and potential future applications

Creator:: Coble, Ashley A., Flinders, Camille A., Homyack, Jessica A., Penaluna, Brooke E., Cronn, Richard C., and Weitemier, Kevin
Abstract:: Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...

Using Satellite Imagery to Count Nesting Albatross from Space

Creator:: Dolliver, Jane E.
Abstract:: One fundamental concern in conservation biology is species abundance. For many taxa, however, these data are costly to obtain via direct observation and thus limited in geographic or temporal scope. Very high-resolution satellite imagery provides a means to address these limitations and provide remotely-sensed counts of large, colonial species. We...
