Mechanisms affecting the bioaccumulation of dietary quinoline by rainbow trout (Salmo gairdneri)

Creator:: Dauble, Dennis D.
Abstract:: Factors that influenced the uptake, storage, and elimination of dietary quinoline by rainbow trout (Salmo gairdneri) were studied to obtain an understanding of the mechanisms affecting the bioaccumulation of dietary contaminants in teleosts. Rainbow trout readily absorbed ¹⁴C-quinoline from pelleted food (1% ration at 138 ug quinoline/g food) and most...

Herbivory by a north temperate stream fish, Acrocheilus alutaceus (Agassiz & Pickering)

Creator:: Lassuy, Dennis R.
Abstract:: Documentation of the seasonal feeding habits and ability to assimilate algae are presented for the first time for a North American grazing stream fish. The chiselmouth, Acrocheilus alutaceus, begins feeding on algal matter in early spring and has deposited large fat reserves prior to an early summer spawning season. A...

The effects of the herbicides Diquat and Dichlobenil on pond invertebrates

Creator:: Wilson, Dennis Carl
Abstract:: The acute toxicity of Diquat (1:1-ethylene-2:2' dipyridylium dibromide) and Dichlobenil (2, 6-dichlorobenzonitrile) to six selected pond invertebrates was determined using the median tolerance limit estimation method. Diquat was more toxic to the amphipod, Hyalella azeteca than to the aquatic insects Callibaetis, Limnephilus, Enallagma, Libellula, and Tendipedidae. The addition of mud...

Factors affecting coho salmon production in Oregon

Creator:: Scarnecchia, Dennis Leslie
Abstract:: Eight scale characters of known hatchery and wild coho salmon (Oncorhynchus kisutch) were compared, and a linear discriminant function was used to determine if hatchery and wild adult coho salmon could be correctly identified by their scales. Eighty-two percent of the hatchery and 89% of the wild fish were correctly...

Seasonal properties of the coyote scent station index

Creator:: Griffith, Dennis Bradley
Abstract:: Six standard coyote scent station index lines and one scentless control line were repeatedly sampled from May through October, 1974, on a 400 square mile study area in Central Oregon. The scent station index remained relatively constant at a mean value of 0.025 from May through mid-August; increased to a...

Ecological effects of nitrogen and sulfur air pollution in the US: what do we know?

Creator:: Greaver, Tara L., Sullivan, Timothy J., Herrick, Jeffrey D., Barber, Mary C., Baron, Jill S., Cosby, Bernard J., Deerhake, Marion E., Dennis, Robin L., Dubois, Jean-Jacques B., Goodale, Christine L., Herlihy, Alan T., Lawrence, Gregory B., Liu, Lingli, Lynch, Jason A., and Novak, Kristopher J.
Abstract:: Four decades after the passage of the US Clean Air Act, air-quality standards are set to protect ecosystems from damage caused by gas-phase nitrogen (N) and sulfur (S) compounds, but not from the deposition of these air pollutants to land and water. Here, we synthesize recent scientific literature on the...

Reproduction in the eastern cottontail rabbit in Oregon

Creator:: Trethewey, Donald Edwin
Abstract:: Reproductive characteristics of introduced eastern cottontail rabbits, Sylvilagus floridanus (J. A. Allen), were determined from 486 rabbits collected between January 1, 1968 and June 30, 1969, near Corvallis, Oregon. Sex ratios were 1:1 for all rabbits collected and for all embryos 20 days or more gestation. On the basis of...
