The decomposition of marine plankton in two-chamber, seawater-filled microbial fuel cells (MFCs) has been investigated and related to resulting chemical changes, electrode potentials, current efficiencies, and microbial diversity. Six experiments were run at various discharge potentials, and a seventh served as an open-circuit control. The plankton consisted of a mixture...
The effects of overcoming rest by application of "near-lethal" (NL)
stress treatments on the subsequent development of cold hardiness of
stem tissues of red-osier dogwood, Comus sericea L., at different rest
stages under three post-environments (0°, 23°, and natural condition)
were studied. NL-heat stress (47°C for one hour) treatment during...
Female participation in high-contact sports has increased
dramatically in the past two decades, raising concern regarding injury to
the female breast and the need for protective equipment. While the use of
chest/breast protectors by women is advocated, little is known of their
efficacy and effect on athletic performance. The purpose...
Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...
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...
The status of wild sheep in North America typifies the plight of many wildlife species in modern times: wild sheep have declined to 10-40% of their numbers during pristine times and on a global scale approximately 31% of Caprine are considered threatened or critical. As human populations and the number...
Genetic differences between early and late forms of
Alaskan chinook salmon (Oncorhynchus tshawytscha) were
identified using two genetic approaches: mitochondrial
DNA (mtDNA) analysis and protein electrophoresis. The
study populations consisted of early- and late-run chinook
salmon in each of the Kenai and Kasilof rivers in Alaska,
and a single population...
This study developed a strategic conservation project for the Oregon Coast Aquarium in Newport, Oregon focusing on a signature species and this aquarium’s conservation focus areas (i.e., marine debris, sustainable fisheries, water quality, climate change). This study also examined the potential for incorporating an ecotourism or wildlife tourism component to...
