Distribution patterns of black-tailed deer (Odocoileus hemionus columbianus) in relation to environment

Creator:: Miller, Frank L.
Abstract:: Direct observation of a known number of black-tailed deer (Odocoileus hemionus columbianus), within the Cedar Creek study enclosure in the Tillamook Burn, Oregon, was carried on throughout 1964. Observations were made from three huts located outside of the enclosure on surrounding prominences. During this period, 1,410 hours of observational time...

Origin and distribution of the fish fauna of the Harney Basin, Oregon

Creator:: Bisson, Peter Andre
Abstract:: A theory of the origin and distribution of fishes in the Harney Basin is presented. Blitzen River, the hydrographically and ecologically isolated creeks, and the upland tributaries of Silvies River all contain populations derived from the basin's Pleistocene connection with Malheur River of the Snake system. Colonization of many streams...

Some chronic effects of exposure to kraft mill effluent on juvenile chinook salmon

Creator:: Tokar, Erick M.
Abstract:: The effects of sublethal concentrations of kraft mill effluents (KME) on the growth, food consumption, and swimming ability of juvenile chinook salmon, Oncorhynchus tschawytscha (Walbaum), were studied from February 1966 to May, 1967. The KME used in these studies was obtained from two pulp and paper mills producing paper from...

Studies on the molluscan and fish hosts of the "salmon poisoning" fluke, Nanophyetus salmincola (Chapin)

Creator:: Gebhardt, Gary Alan.
Abstract:: This study¹ was undertaken: (1) to obtain information on the distribution of the snail, Oxytrema silicula, in three coastal rivers in Oregon, and the seasonal incidence of infection in these snails and in snails from an inland stream, with the cercariae of the trematode, Nanophyetus salinincola; (2) to follow cercarial...

Factors affecting the abundance of fall chinook salmon in the Columbia River

Creator:: Van Hyning, Jack M.
Abstract:: A study of the population ecology of Columbia River fall chinook salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt to determine the cause of a serious decline in this run which occurred in the early 1950's. Fluctuations in abundance of major salmon runs the North Pacific were examined to...

Definitive hosts of the trematode vector, Nanophyetus salmincola

Creator:: Schlegel, Michael Wesley
Abstract:: Of 149 wild animals from two western Oregon river drainage areas and other localities in which "salmon poisoning" disease (SPD) is enzootic, including ten mammalian and two avian species, 79 harbored Nanophyetus salmincola, the SPD vector. The shorttail weasel, Mustela erminea; river otter, Lutra canadensis; spotted skunk, Spilogale putorius; Norway...

Effects of logging on the spawning bed environment in two Oregon coastal streams

Creator:: Ringler, Neil Harrison
Abstract:: The effects of two patterns of logging on the intragravel environment were studied in three Oregon coastal streams between June 1968 and June 1969. The watershed of one stream (Needle Branch) had been clearcut, and that of a second stream (Deer Creek) cut in staggered settings in 1966. A third...

A review of the Gadopsidae, with a description of a new species from Tasmania

Creator:: Parrish, Richard H.
Abstract:: The taxonomic placement of Gadopsidae is discussed and an evaluation of its osteological relationships with related families is given. Similarities to the more primitive genera of the trachinoids, notothenioids, and uranoscopoids are noted and the inclusion of Gadopsidae in the Trachinoidae is recommended. A description of the geological history of...
