Arribada nesting of olive ridley sea turtles (Lepidochelys olivacea) at La Escobilla, Mexico

Creator:: Ocana, Melissa Ann S.
Abstract:: Olive ridley sea turtles (Lepidochelys olivacea) present an interesting case study of the conservation of wildlife species that aggregate in high densities and have served as resources for human consumption. Ridleys exhibit synchronized mass-nesting behavior, during events called "arribadas," where thousands of females lay eggs together in a small area...

Phase equilibria for the sucrose-potassium chloride-water system on Dowex 50 W X 4 resin (K⁺) at 90⁰C

Creator:: Kalwani, Shantukumar Laxmidas
Abstract:: Equilibrium data for the sucrose-potassium chloride-water system were taken for Dowex 50 W X 4 resin at 90° C. The sugar concentration was varied from 0% to 60% by weight, and the salt content, from 0% to 6% by weight. Because shrinkage of the resin due to salt absorption was...

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....

Seasonal movement patterns and habitat use of westslope cutthroat trout in two headwater tributary streams of the John Day River

Creator:: Starcevich, Steven J.
Abstract:: Radiotelemetry was used to study the seasonal movements and habitat use of adult westslope cutthroat trout Oncorhynchus clarki lewisi in Roberts Creek and Rail Creek, headwater tributaries of the John Day River, Oregon, from September 2000 to December 2001. The objectives were to (1) describe adult cutthroat trout life history...

Factors affecting the antimicrobial activity of vitamin K₅

Creator:: Merrifield, Larry Stanford
Abstract:: Vitamin K₅, 4-amino-2-methyl-1-naphthol hydrochloride, a water soluble analog of vitamin K has been shown to possess an antimicrobial activity toward many bacteria, molds, and yeast. Much of the work reported in the literature is on its use as a food preservative, and it was the purpose of this study to...

Development of a singulation device for stonefly larva

Creator:: Williams, Kate S. (Kate Shreeve)
Abstract:: Population counts of aquatic insects can be a credible indicator of the overall health of a waterway. Stonefly (Plecoptera) larva are very sensitive to chemicals present within the waterway, however obtaining population counts of the larvae can be very labor intensive and thus costly. The BugID project has been working...

Distortion-induced fatigue cracking of girder-to-crossbeam connection

Creator:: Aljutaili, Dhari S.
Abstract:: Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...

Automating aquatic insect identification through pattern recognition

Creator:: Thomas, Joshua K.
Abstract:: Aquatic insect population counts can be a good indicator of the health, or water quality, of rivers and streams. Stoneflies (Plecoptera) are particularly susceptible to pollution in streams. However, today’s current method for obtaining these population counts requires biologists to examine individual specimens under a microscope for identification to the...
