Implications of morphological variation among populations of California roach Lavinia symmetricus (Cyprinidae) for conservation policy
Larry R. Brown, Peter B. Moyle, William A. Bennett, Brian D. Quelvog
1992, Biological Conservation (62) 1-10
The California roach Lavinia symmetricus is a small cyprinid native to Central California. Populations of roach are presently isolated from one another due to degradation of stream habitats between them. We examined eight populations, each from a tributary system of the San Joaquin River, to determine if morphological differences existed among them....
Colloid formation during waste form reaction: Implications for nuclear waste disposal
J. K. Bates, J. Bradley, A. Teetsov, C. R. Bradley, Marilyn R. Buchholtz ten Brink
1992, Science (256) 649-651
Insoluble plutonium- and americium-bearing colloidal particles formed during simulated weathering of a high-level nuclear waste glass. Nearly 100 percent of the total plutonium and americium in test ground water was concentrated in these submicrometer particles. These results indicate that models of actinide mobility and repository integrity, which assume complete solubility...

A technique for estimating seed production of common moist soil plants
Murray K. Laubhan
1992, Report, Waterfowl Management Handbook
Seeds of native herbaceous vegetation adapted to germination in hydric soils (i.e., moist-soil plants) provide waterfowl with nutritional resources including essential amino acids, vitamins, and minerals that occur only in small amounts or are absent in other foods. These elements are essential for waterfowl to successfully complete aspects of...

Topographic mapping
Water Resources Division, U.S. Geological Survey
1992, Report
The U.S. Geological Survey (USGS) produced its first topographic map in 1879, the same year it was established. Today, more than 100 years and millions of map copies later, topographic mapping is still a central activity for the USGS. The topographic map remains an indispensable tool for government, science, industry,...

Use of remote sensing and GIS to identify Flamingo habitat in the Argentine Altiplano
Susan C. Boyle, Roger M. Hoffer, Terence P. Boyle, Enrique H. Bucher
1992, Bulletin of the Ecological Society of America (73)
The Argentine altiplano is a remote area which has never been adequately mapped. It is an arid region with harsh climate, little vegetation, sparse population, and an average elevation of over 3,500 feet. Little is known about the large populations of three species of flamingos which nest and...
Contribution of fish community metrics to the index of biotic integrity in two Ozark rivers
Nancy J. Hoefs, Terence P. Boyle
1992, Ecological Indicators (1) 283-303
Flow regime, energy source, water quality, and habitat structure within stream systems play major roles in controlling the structure of resident fish communities (Gorman and Karr, 1978; Karr and Dudley, 1981; Schlosser, 1982). Based on the hypothesis that there are predictable relationships between stream variables and fish community structure, overall...

Frictional strength and the effective pressure law of montmorillonite and illite clays
C. Morrow, B. Radney, J. Byerlee
1992, International Geophysics (51) 69-88
Low-strength clay minerals are a common constituent of fault gouges, and are often cited as a possible explanation for the low ambient shear stresses along the San Andreas fault inferred from heat flow constraints and in situ stress measurements. Montmorillonite, the weakest of the clay minerals, undergoes a gradual phase...

Miocene intensification of upwelling along the California margin as recorded in siliceous facies of the Monterey Formation and offshore DSDP sites
Lisa D. White, Robert E. Garrison, John A. Barron
C. P. Summerhayes, W.L. Prell, K.C. Emeis, editor(s)
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,...
