Microhabitat selection of brood-rearing sites by greater sage-grouse in Carbon County, Wyoming

Creator:: Schreiber, Leslie A.
Abstract:: Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...

The fishes of Tillamook Bay

Creator:: Bottom, Dan, Forsberg, Brent O., and Oregon. Dept. of Fish and Wildlife. Research and Development Section
Abstract:: Sampling with seine and trawl from May 1974 to November 1976 indicated that the species composition and distribution of fishes in Tillamook Bay through time is primarily related to the movements of marine species in and out of the estuary. Northern anchovy (Engraulis mordax), surf smelt (Hypomesus pretiosus), and shiner...

Male Greater Sage-Grouse Detectability on Leks

Creator:: Fremgen, Aleshia L.
Abstract:: It is unlikely all male sage-grouse are detected during lek counts, which could complicate the use of lek counts as an index to population abundance. Understanding factors that influence detection probabilities will allow managers to more accurately estimate the number of males present on leks. We fitted 410 males with...

Results of inquiries to other agencies requesting methods used for seal control

Creator:: Robinson, William L.
Abstract:: The Columbia River seal control program operated under legislative authority. The Fish Commission paid has paid a bounty since 1936 and hired a seal hunter during 1958-1970. In May 1972, the author wrote to resource management and research agencies in 18 seaboard states, Canada, and Scotland to seek suggestions for...

Use of tethered prey for estimating the impact of the invasive European green crab

Creator:: Hauck, Laura L.
Abstract:: Various mollusks, including small bivalves and gastropod snails, are a common food source for intertidal crabs. Prey opening techniques used on hard-shell prey are dependent on claw size and morphology. For example, large, strong claws can crush a snail outright while smaller, weaker claws leave characteristic peels, pulls and upper...

Ecological baselines for Oregon's coast: a report for agencies that manage Oregon's coastal habitats for ecological and economic sustainability, and for all who are interested in the welfare of wildlife that inhabit our coast and its estuaries

Creator:: Hall, Roberta L., Ebert, Thomas A., Gilden, Jennifer S., Hatch, David R., Mrakovcich, Karina Lorenz, and Smith, Courtland L.
Abstract:: Against the backdrop of growing concern about dead zones, rare and endangered sea mammals, depletion of Oregon’s once‐abundant fish stocks, acidification threatening coastal molluscs, and proposals for marine reserves along Oregon’s coastline, a multidisciplinary group of scientists was called together in 2008 to discuss what is known about Oregon’s coastal...

Some factors influencing the trends of salmon populations in Oregon

Creator:: McKernan, Donald L. (Donald Lynn), 1918-1979, Johnson, Donald R., Hodges, John I., and Oregon. Fish Commission
Abstract:: Three factors were found to be significantly correlated with the fluctuations and trends in silver salmon production in Oregon. Logging was found to adversely affect the runs of salmon in later years. Exceptional winter floods seem to produce poor resulting runs. Low summer water flows also appear to produce lower...

Texture analysis riparian coniferous forest ADAR imagery to identify potential ecological indicators for monitoring

Creator:: Barker, Jerry R., Bollman, Mike, Fiorella, M., Bradshaw, Gay, and Ringold, P. L.
Abstract:: The Airborne Data Acquisition and Registration (ADAR) remote sensing system captured one-meter resolution imagery of 25 different riparian sites in drift Creek Basin of coastal northwestern Oregon, USA. The multispectral, digital data characterized riparian areas with the intent to develop ecological indicators for long-term monitoring.

Statistical summaries of streamflow data in Oregon : Volume 2, annual low and high flow, and instantaneous peak flow

Creator:: Wellman, Roy E, Gordon, Janice M., Moffatt, R. L., and Oregon. Water Resources Department
Abstract:: Statistical summaries of streamfiow data at 358 stream-gaging sites are presented to aid in appraising the hydrology of river basins in Oregon. Records for 36 stream-gaging stations were compiled into separate periods because of changes in streamflow regulation during the period of data collection. Statistical summaries for the periods before...
