Drainage development of the Green River Basin in southwestern Wyoming and its bearing on fish biogeography, neotectonics, and paleoclimates.
W. R. Hansen
1985, Mountain Geologist (22) 192-204
The Upper Green River flows southward out of the Green River Basin through a series of deep canyons across the Uinta Mountains in a course that post-dates the deposition of the Bishop Conglomerate (Oligocene). After the Eocene lakes disappeared, drainage was generally eastward across the present Continental Divide, until the...
Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD (390-0765)
Chandler S. Robbins
1985, North American Bird Bander (10) 56-56
My being away nearly all of September and on half the October weekends cut deeply into this season's banding. Totals for permanent residents and winter residents were close to normal, but numbers of the transient species are not at all comparable with other years. The only species that seemed more...
Foraging recruitment by the Giant Tropical Ant Paraponera clavata (Hymenoptera, Formicidae)
Bruce A. Barrett, Clive D. Jorgenson, Sandra J. Looman
1985, Pan-Pacific Entomologist (61) 334-338
Increased foraging of an exceptionally abundant, but ephemeral, food source by ants can result from foraging excitement that does not include pheromone trails, tandem running, or from recruitment of other workers along pheromone trails (Carrol and Janzen, 1973). They also provided rationale for two types of short-lived pheromone trails resulting...
The Emperor Goose
Margaret R. Petersen
Roger L. Di Silvestro, editor(s)
1985, Report, Audubon wildlife report 1985
Many ornithologists believe the emperor goose (Chen canagicus) is the most beautiful goose in North America. Detailed descriptions of its plumage can be found in Palmer1 and a general description in Bellrose.2 Emperor geese are rather short and squatty, with yellow-orange feet and pink bills. Their bluish-gray body feathers are...
Benthic foraminifera as indicators of potential petroleum sources
C. Wylie Poag
Bob F. Perkins, Gene B. Martin, editor(s)
1985, Conference Paper, Habitat of oil and gas in the Gulf Coast: Proceedings of the fourth annual research conference, Gulf Coast Section, Society of Economic Paleontologists and Mineralogists Foundation

Ecological effects of rubble-mound breakwater construction and channel dredging at West Harbor, Ohio (western Lake Erie)
Bruce A. Manny, Donald W. Schloesser, Charles L. Brown, John R. P. French III
1985, Technical Report EL-85-10
The investigation reported herein indicated that breakwater construction and associated channel dredging activities by the US Army Corps of Engineers in western Lake Erie at the entrance to West Harbor (Ohio) had no detectable adverse impacts on the distributions or abundances of macrozoobenthos and fishes. Rather, increases were noted in...
Major and trace-element analyses of acid mine waters in the Leviathan Mine drainage basin, California/Nevada; October, 1981 to October, 1982
J.W. Ball, D. Kirk Nordstrom
1985, Water-Resources Investigations Report 85-4169
Water issuing from the inactive Leviathan open-pit sulfur mine has caused serious degradation of the water quality in the Leviathan/Bryant Creek drainage basin which drains into the East Fork of the Carson River. As part of a pollution abatement project of the California Regional Water Quality Control Board, the U.S....
Review of fish species introduced into the Great Lakes, 1819-1974
Lee Emery
1985, Technical Report 45
This review is based on an extensive literature search, combined with updated information obtained from biologists, and unpublished reports from private, state, and federal organizations throughout the Great Lakes basin. The chronological review lists 34 species of fishes in 13 families that were introduced into the basin from 1819 to...
New approach to calibrating bed load samplers
D. W. Hubbell, H.H. Stevens, J. V. Skinner, J.P. Beverage
1985, Journal of Hydraulic Engineering (111) 677-694
Cyclic variations in bed load discharge at a point, which are an inherent part of the process of bed load movement, complicate calibration of bed load samplers and preclude the use of average rates to define sampling efficiencies. Calibration curves, rather than efficiencies, are derived by two independent methods using...
A heat-flow reconnaissance of southeastern Alaska
J.H. Sass, L.A. Lawver, R. J. Munroe
1985, Canadian Journal of Earth Sciences (22) 416-421
Heat flow was measured at nine sites in crystalline and sedimentary rocks of southeastern Alaska. Seven of the sites, located between 115 and 155 km landward of the Queen Charlotte – Fairweather transform fault, have an average heat flow of 59 ± 6 mW m−2. This value is significantly higher than the mean of 42 mW m−2 in...
WATER CHEMISTRY AND MINERALOGY OF MORGAN AND GROWLER HOT SPRINGS, LASSEN KGRA, CALIFORNIA.
J. Michael Thompson, Terry E.C. Keith, Jerry J. Consul
1985, Conference Paper, Transactions - Geothermal Resources Council
Because these springs contain substantial amounts of dissolved chloride, halite and sylvite are found above the water level as evaporitic deposits, along with gypsum. One spring is depositing pyrite that contains significant amounts of arsenic, antimony, and thallium. A yellow compound, composed of arsenic and sulfur, is being deposited in...
