Structure, abundance, and distribution of pelagic zooplankton in a deep, oligotrophic Caldera Lake

Creator:: Karnaugh, Elena N.
Abstract:: From July 1985 to April 1987 the pelagic zooplankton community of Crater Lake, Oregon was studied to determine taxonomic structure, absolute and relative densities, and spatial and temporal distributional patterns. Samples were collected using vertically-towed zooplankton nets. The community structure consisted of two cladoceran and nine rotifer species, which were...

Diver observations of community structure on a subarctic marine artificial reef in Whittier, Alaska

Creator:: Levy, Charlotte
Abstract:: Increased coastal development poses a potential threat to nearshore habitats in Alaska, and artificial reefs (AR) are an increasingly popular tool for mitigating habitat loss. Although well studied in tropical and temperate locations, less is known about AR efficacy in high latitude locations. Since ARs are heavily influenced by ecological...

Morphological diversity of the speckled dace (Rhinichthys osculus) in Oregon's desert springs

Creator:: Peterson, Erin D., Hoekzema, Kendra, Bronaugh, Whitcomb, and Sidlauskas, Brian
Abstract:: The Speckled dace (Rhinichthys osculus) is the most widespread minnow in western North America (Gilbert and Williams, 2002). It has diversified widely across its range—both morphologically and genetically—and as such might rightly be called a species complex. Our ongoing work aims to determine where boundaries between potentially undescribed species lie...

Temperature effects on Pacific oyster embryos subjected to spent sulfite liquor

Creator:: Will, Theodore
Abstract:: An exploratory study of 48-hour Pacific oyster embryo bioassays employing spent sulfite liquor (SSL) in test concentrations ranging from 10 to 45 ppm was made at two incubation temperatures, 20° and 24° C. Fourteen separate bioassays, each employing embryos originating from three to four different parentages, were conducted at the...

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...

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...

The influence of some environmental factors on the distribution of fishes in Upper Klamath Lake

Creator:: Vincent, David Thomas
Abstract:: The fishes of Upper Klamath Lake appeared to distribute themselves in three general groups during the summers of 1964 and 1965: (1) the chubs--unrestricted as to distribution with slight seasonal variations; (2) rainbow trout and yellow perch -- restricted to certain water conditions that exist only along the northern marsh...

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...

The black crappie, Pomoxis nigromaculatus, as a farm pond fish in Oregon

Creator:: Stolte, Lawrence
Abstract:: The black crappie was evaluated as a pond fish in four experimental ponds in the Willamette Valley. Two ponds were stocked with largemouth bass, bluegill sunfish, and black crappie (1:9:3), and two ponds with largemouth bass and black crappie (1:3). Total biomass was greatest in the three-species ponds (80 kg/...
