Riparian vegetation composition and structure associated with channel morphology of headwater meadow streams in the Blue Mountains, northeast Oregon

Creator:: Toledo, Zachary O.
Abstract:: Relationships between the structure and composition of riparian vegetation with channel morphology were examined in three montane meadow streams in the headwaters of the Upper Grande Ronde River and North Fork John Day River in the Blue Mountains, northeast Oregon. Vegetation composition, root biomass, and channel morphology cross-sections were sampled...

Effects of oil and natural gas development on territory occupancy of ferruginous hawks and golden eagles in Wyoming, USA

Creator:: Wallace, Zachary P.
Abstract:: Energy development is expanding rapidly across the western US. Negative effects have been documented for some wildlife, but consequences of development are unclear for other taxa, including raptors. We had the opportunity to examine effects of oil and natural gas development on two raptor species of conservation concern, ferruginous hawks...

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...

Development of a Structured Adaptive Approach to Klamath Basin Sucker Recovery Planning

Creator:: Barajas, Miguel F.
Abstract:: Listed as endangered in 1988, the Lost River sucker (Deltistes luxatus) and Shortnose sucker (Chasmistes brevirostris) were once abundant and widely distributed in the Klamath Basin in Southern Oregon and Northern California. Populations of both species have been declining since the late 1960’s. Factors thought responsible for declines include naturally...

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...

Pre- and Post-settlement Processes of Northern Rock Sole (Lepidopsetta polyxystra) in Relation to Interannual Variability in Temperature and Productivity in the Gulf of Alaska

Creator:: Fedewa, Erin J.
Abstract:: Understanding the effects of climate variability on growth dynamics and timing of early life history events in marine fishes can provide insights into survival, recruitment and productivity. Field collections (2005, 2007, 2009-2011) were combined with otolith microstructural analysis to examine interannual variation in larval and juvenile growth rates, size at...

Linking Moral Obligations, Assumption-based Research, and Structured Decision Making to Inform Bull Trout Recovery

Creator:: Brignon, William R.
Abstract:: More than 1500 species of plants and animals in the United States are listed as threatened or endangered under the Endangered Species Act (ESA). The U.S. Departments of Interior and Commerce are required, under Section 4(f)(1) of the ESA, to develop recovery plans for ESA-listed species under the respective agency...

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...
