Sulfide metabolism in Lucina floridana, a sulfur symbiont-containing marine clam

Creator:: Larabee, Jeannine Kay
Abstract:: Lucina floridana is an intertidal clam that contains intracellular, sulfur-oxidizing symbiotic bacteria in its gills. These bacteria are chemolithoautotrophic, using the energy from the oxidation of reduced sulfur compounds to power carbon fixation. Although sulfide is an energy-rich compound, it is also toxic to aerobic metabolism and autooxidizes in the...

Drift, wood, and grazing cattle : macroinvertebrates in managed streams

Creator:: Reed, T. L.
Abstract:: The importance of active-entry drift at a community-scale was evaluated by testing whether the placement of wood in streams affected the abundance of Baetis spp. mayflies in drift. Baetis were chosen because they use drift as a behavioral strategy and are important in salmonid diets. The density of woody debris...

Field checking the National Wetlands Inventory at South Slough, Oregon

Creator:: Graves, Jonathan K.
Abstract:: The U.S. Fish and Wildlife Service's National Wetlands Inventory (NWI) was developed to map U.S. wetlands comprehensively, following the Cowardin classification system. Wetlands are mapped by the NWI using small scale aerial photographs, but the inventory is not field checked in detail. The accuracy of this inventory has been questioned....

Archaeological Symbols of Status and Authority : Fort Hoskins. Oregon. 1856-1865

Creator:: Bowyer, Gary C.
Abstract:: Fort Hoskins is located near Kings Valley, approximately 16 miles from Corvallis. The Fort, built after the Rogue Wars of the 1850s, was intended to safeguard the newly created Indian reserves. During its' ten-years of existence, U.S. Army Regulars manned the Fort from 1856-1861 while volunteers from California, Washington, and...

Micropropagation of Pyrus rootstocks

Creator:: Yeo, Dennis
Abstract:: The availability of new pear rootstocks could be increased by development of an efficient micropropagation system. Many P. calleryana, P. betulifolia and P. communis rootstocks are resistant to many pear diseases and are graft compatible with leading cultivars. Explains of three potentially useful rootstock selections P. calleryana Decne 'OPR 157',...

Characteristics of pools used by adult summer steelhead (Oncorhynchus mykiss) in the Steamboat Creek Basin, North Umpqua River, Oregon

Creator:: Baigun, Claudio Rafael Mariano
Abstract:: This study examined features of deep pool (>0.8 m mean depth) used by adult summer steelhead in Steamboat Creek (1991-1992). Steamboat Creek had a heterogenous thermal profile, with some segments exceeding preferred temperature of steelhead. Deep pools were scarce (4% of the total habitat units) and 39% of them were...

Assessment of impacts of Canada geese on wheat production

Creator:: Louhaichi, Mounir
Abstract:: Numbers of wild Canada geese (Branta canadensis) have increased dramatically during the past 30 years in the lower Columbia and Willamette Valley systems. The damage they cause by grazing and trampling plants can be substantial. The objectives of this research were to: 1) Develop methods that provide reliable estimates of...

Epidemiology and population biology of Inonotus tomentosus as a pathogen of forests of British Columbia

Creator:: Lewis, Katherine JoAnn
Abstract:: The root disease fungus Inonotus tomentosus, common in the old growth boreal forests of British Columbia, poses a threat to the health of second growth forests established on sites with a previous history of root disease. Colonized stumps occur in groups of 1 to 6; the groups are clumped within...

Influence of channel constraint on primary production, preiphyton biomass, and macroinvertebrate biomass in streams of the Oregon Coast Range

Creator:: Zucker, Steven J.
Abstract:: Differences in primary production and periphyton and macroinvertebrate biomass between pairs of constrained (valley floor width of less than twice the active channel width) and unconstrained reaches were investigated in Elk River and four tributaries in southwest Oregon. In August 1991, macroinvertebrates were sampled from individual cobbles, and rocks were...
