On forming an Ornithological Council
Richard C. Banks
1991, The Auk (108) 208-210
It has begun to bother me that the ornithological societies seem to be playing an extremely minor role in anything to do with conserving, preserving, or salvaging the environment. We realize-or we tell each other that we do-that birds are an important part of the world's ecosystems, that they can...

Tectonic evolution of submarine canyons along the California continental margin
H. Gary Greene, Samuel H. Clarke Jr., Michael P. Kennedy
Robert H. Osborne, editor(s)
1991, Book chapter, From shoreline to abyss: Contributions in marine geology in honor of Francis Parker Shepard
The development of submarine canyons along active-plate margins commonly is influenced by tectonic processes. Recent studies of submarine canyons along the transform margin of western North America show that the origin and subsequent evolution of many canyons are correlatable with plate motion and plate-margin deformation. Elements of canyon morphology such...

Feeding rate of slimy sculpin and burbot on young lake charr in laboratory reefs
Jacqueline F. Savino, Mary G. Henry
1991, Environmental Biology of Fishes (31) 275-282
Predation and contaminants are two possible factors in the poor recruitment of young lake charr Salvelinus namaycush in the Great Lakes. We measured the feeding rate of slimy sculpins Cottus cognatus and burbot Lota lota on young lake charr (uncontaminated young from eggs of a hatchery brood stock and contaminated...
Intrinsic Nd, Pb, and Sr isotopic heterogeneities exhibited by the Lherz Alpine Peridotite Massif, French Pyrenees
S.B. Mukasa, J.W. Shervais, H. G. Wilshire, J. E. Nielson
1991, Journal of Petrology (Special) 117-134
Optically clear, acid-leached Cr-diopside, Al-augite, pargasitic amphibole, and phlogopite from peridotite and ultramafic dikes of the Lherz massif (French Pyrenees) exhibit chemical and isotopic heterogeneities indicative of a complex history. The data cover a wide range on the 143Nd/144Nd vs. 87Sr/86Sr covariation diagram, encompassing much of the mantle array and a...

Magmatic evolution of the Gulf of California rift
Michael G. Sawlan
J. Paul Dauphin, Bernd R. T. Simoneit, editor(s)
1991, Book chapter, The gulf and peninsular province of the Californias
Magmatic events in the Baja peninsula-Gulf of California region are closely related to sequential tectonic regimes of: (1) late Tertiary subduction beneath the continental margin until ~16 to 12.5 Ma; and (2) continental to oceanic rifting that began about 13 Ma. Orogenic calcalkaline volcanic rocks formed subparallel belts of rhyolite...
[Book review] Birds of Malheur National Wildlife Refuge, Oregon
M. Ralph Browning
1991, The Auk (108) 1003-1004
Although John Warham has worked for at least 40 years on procellariids, this book is much more than just a summary of a distinguished research career. It is a useful synthesis of the vast and often obscure literature on the more than 100 species of shearwaters, petrels, albatrosses, and fulmars...
The relationship between stable oxygen and hydrogen isotope ratios of water in astomatal plants
Lee W. Cooper, Michael J. DeNiro, Jon E. Keeley
H. P. Taylor Jr., J. R. O’Neil, I.R. Kaplan, editor(s)
1991, Book chapter, Stable Isotope Geochemistry: A Tribute to Samuel Epstein.
Isotropic fractination of leaf water during transpiration is influenced by both equilibrium and kinetic factors. Previous workers have predicted that the influence of each factor varies depending upon the path of water loss,m whether centralized through stomata, or diffuse through the cuticle. We studied the relationship between the...

On the observation, characterisation, and predictive GIS mapping of strong ground shaking for seismic zonation
Roger D. Borcherdt
1991, Bulletin of the New Zealand Society for Earthquake Engineering (24) 287-305
Tragic earthquakes of the last decade in Mexico, Armenia, and the United States have re-emphasised the importance of local geologic site conditions in determining amounts of damage and consequent loss of life. Extensive data sets in the San Francisco Bay region on strong earthquake ground motions, the damage distributions from...
Thirty-eighth supplement to the American Ornithologists' Union Check-list of North American birds
Burt L. Monroe Jr., Richard C. Banks, John W. Fitzpatrick, Thomas R. Howell, Ned K. Johnson, Henri Ouellet, J.V. Remsen, Robert W. Storer
1991, The Auk (108) 750-754
This fourth supplement after the 6th edition (1983) of the AOU "Check-list of North American Birds" consists of changes adopted by the Committee on Classification and Nomenclature between 1 March 1989 and 1 March 1991. The changes fall into eight categories: (1) five species (Ixobrychus sinensis, Porphyrula flavirostris, Sterna...

The Great Salt Lake
W.R. Hassibe, W.G. Keck
1991, Report
The western part of the conterminous United States is often thought of as being a desert without any large bodies of water. In the desert area of western Utah, however, lies Great Salt Lake, which in 1986 covered approximately 2,300 square miles and contained 30 million acre-feet of water (an...
Effects of roadside habitat and fox density on a snow track survey for foxes in Ohio
Thomas R. Stanley, Jonathan Bart
1991, Ohio Journal of Science (91) 186-187
Many methods have been used to survey red fox (Vulpes vulpes) and gray fox (Urocyon dnereoargenteus) populations. However, none has proven entirely satisfactory, and wild foxes remain one of the most difficult economically important wildlife species to monitor. In this study we evaluated the reliability of a snow track survey...
Evaluation of the instream flow incremental methodology by U.S. Fish and Wildlife Service field users
Carl L. Armour, Jonathan G. Taylor
1991, Fisheries (16) 36-43
This paper summarizes results of a survey conducted in 1988 of 57 U.S. Fish and Wildlife Service field offices. The purpose was to document opinions of biologists experienced in applying the Instream Flow Incremental Methodology (IFIM). Responses were received from 35 offices where 616 IFIM applications were reported. The existence...
Weights and hematology of wild black bears during hibernation
Glenn D. DelGiudice, Lynn L. Rogers, Arthur W. Allen, U.S. Seal
1991, Journal of Wildlife Diseases (27) 637-642
We compared weights and hematological profiles of adult (>3-yr-old) female black bears (Ursus americanus) during hibernation (after 8 January). We handled 28 bears one to four times (total of 47) over 4 yr of varying mast and berry production. Mean weight of lactating...
