1992, Book chapter, Upwelling systems: Evolution Since the early Miocene
Diatomaceous sediments and their diagenetic equivalents in the Monterey Formation record a variable history of upwelling along the California margin. Distrinctive dark opal-CT and quartz chertz found in distal basins of the Monterey Formation are the result of burial diagenesis of pure biosiliceous oozes (biosiliceous oozes without significant admixtures of...

Human disturbances of waterfowl: causes, effects, and management
C. E. Korschgen, R.B. Dahlgren
1992, Fish and Wildlife Leaflet 13.2.15
Human disturbances of waterfowl can be intentional or unintentional. They may result from overt or directed activities or may be ancillary to activities not initially thought to be of concern to birds. Some of these disturbances are manifested by alertness, fright (obvious or inapparent), flight, swimming, disablement, or death. Therefore,...

Human disturbances of waterfowl: An annotated bibliography
R.B. Dahlgren, C. E. Korschgen
1992, Resource Publication 188
The expansion of outdoor recreation greatly increased the interaction between the public, waterfowl, and waterfowl habitat. The effects of these interactions on waterfowl habitats are visible and obvious, whereas the effects of interactions that disrupt the normal behavior of waterfowl are subtle and often overlooked, but perhaps...
Effects of the lampricide 3-trifluoromethyl-4-nitrophenol on dissolved oxygen in aquatic systems
V. K. Dawson, D.A. Johnson, J.F. Sullivan
1992, Technical Report 57
The effects of the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) on dissolved oxygen and other water- quality characteristics were evaluated in a series of test chambers under selected combinations of water, sediment, TFM, and exposure to sunlight. Concentrations of TFM gradually decreased over time, especially in the presence of sediment and...

Effect of pH on the toxicity of TFM to sea lamprey larvae and nontarget species during a stream treatment
T.D. Bills, D.A. Johnson
1992, Technical Report 57
Treatment of tributaries to the Great Lakes with the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) occasionally results in incomplete kills of sea lamprey larvae (Petromyzon marinus ) or excessive mortality of nontarget fish. In continuous-flow toxicity tests conducted on the Millecoquins River, Michigan, TFM remained selective for sea lamprey at...

Selection of prey by walleyes in the Ohio waters of the central basin of Lake Erie, 1985-1987
David R. Wolfert, Michael T. Bur
1992, Resource Publication 182
Walleyes (Stizostedion vitreum vitreum) were collected at five locations in the central basin of Lake Erie in 1985-87. The contents of the fishes' stomachs were examined to identify the species of prey. The seasonal availability of potential prey was determined from sampling with trawl tows. Food electivity indexes...

Experimental evidence for the effects of polyphenolic compounds from Dictyoneurum californicum (Phaeophyta; Laminariales) on feeding rate and growth in the red abalone Haliotus rufescens Swainson
F.C. Winter, J. A. Estes
1992, Journal of Experimental Marine Biology and Ecology (155) 263-277
The effects of polyphenolic compounds from brown algae on grazing and growth rate of the California red abalone Haliotis rufescens Swainson were examined. Abalone consumed three phenolic-poor algal species, Laminaria sinclarii (Harvey) Farlow, Macrocystis pyrifera Agardh, and Nereocystis luetkeana Postels et Ruprecht (mean phenolic content = 0.52% dry mass), at a greater rate than two phenolic-rich species, Dictyoneurum californicum Ruprecht...
Walking of the shore crab Pachygrapsis crassipes in its two natural environments
Clifford A. Hui
1992, Journal of Experimental Biology (165) 213-227
Video analyses of crabs walking on smooth and rocky terrains when in air and when submerged in water were conducted. Modifications of walking in the two environments, between which the animal’s weight changes sixfold, are consistent with the goals of maximizing ease of walking and minimizing risk of injury. The...

Commissioned Review. Carbon: freshwater plants
Jon E. Keeley, D.R. Sandquist
1992, Plant, Cell & Environment (15) 1021-1035
δ13C values for freshwater aquatic plant matter varies from −11 to −50‰ and is not a clear indicator of photosynthetic pathway as in terrestrial plants. Several factors affect δ13C of aquatic plant matter. These include: (1) The δ13C signature of the source carbon has been observed to range from +1‰...
Late Cretaceous inoceramid bivalves of the Kuskokwim Basin, southwestern Alaska, and their implications for basin evolution
W.P. Elder, S. E. Box
1992, Journal of Paleontology (66)
Upper Cretaceous rocks of the Kuskokwim Group are exposed in a large region of southwestern Alaska and are mainly composed of deformed turbidite deposits that contain few fossils other than inoceramid bivalves. This paper documents the taxonomy of the inoceramids in the Kuskokwim Group, develops an inoceramid...
Electromagnetic methods for mapping freshwater lenses on Micronesian atoll islands
S. S. Anthony
1992, Journal of Hydrology (137) 99-111
The overall shape of freshwater lenses can be determined by applying electromagnetic methods and inverse layered-earth modeling to the mapping of atoll island freshwater lenses. Conductivity profiles were run across the width of the inhabited islands at Mwoakilloa, Pingelap, and Sapwuahfik atolls of the Pohnpei State, Federated States...
