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...

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...

Historical and current forest landscapes in Eastern Oregon and Washington. Part 2. Linking vegetation characteristics to potential fire behavior and related smoke production

Creator:: Huff, Mark H., Ottmar, Roger D., Alvarado, Ernesto, Vinnanek, Robert E., Lehmkuhl, John F., Hessburg, Paul F., and Everett, Richard L.
Abstract:: We compared the potential fire behavior and smoke production of historical and current time periods based on vegetative conditions in forty-nine 5100- to 13 500-hectare watersheds in six river basins in eastern Oregon and Washington. Vegetation composition, structure, and patterns were attributed and mapped from aerial photographs taken from 1932...

The biology and external morphology of bees ; with a synopsis of the genera of northwestern America

Creator:: Stephen, William Procuronoff, 1927-, Bohart, George Edward, and Torchio, Philip F.
Abstract:: ENTOMOLOGISTS, BOTANISTS, and AGRICULTURISTS all have occasion to concern themselves with bees. The en-tomologist is fascinated by their complex behavior pat-terns, the botanist needs to evaluate their significance infloral biology, and the agriculturist must take them into account as vital factors in crop production. Finally, the apiculturist often wishes to...

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.

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...
