Possible relationships between trichinellosis and abnormal behavior in bears
David E. Worley, Kenneth R. Greer, Daniel A. Palmisciano
1983, Book chapter, International Conference on Bear Research and Management
Data compiled from parasite studies of grizzly bears (Ursus arctos) and black bears (U. americanus) in the Yellowstone and Glacier National Park populations and surrounding areas of Montana and Wyoming during 1969-79 are reviewed with reference to the possible influence of infection with the muscleworm Trichinella sp. on bear behavior....
Grizzly bear: habitat relationships in the Yellowstone area
Bonnie M. Blanchard
1983, Bears: Their Biology and Management (5) 118-123
Habitat use by grizzly bears (Ursus arctos) was studied from 1977 through 1979 in a 20,000-km2 area with Yellowstone National Park in the center. Of 1826 aerial radio locations of 46 instrumental grizzlies, 90% were in timber. Three-fourths of the locations were 100 m or less from an edge between...
Lead accumulation and depression of δ-aminolevulinic acid dehydratase (ALAD) in young birds fed automotive waste oil
W. C. Eastin Jr., David J. Hoffman, C. T. O’Leary
1983, Archives of Environmental Contamination and Toxicology (12) 31-35
The effects of a 3-week dietary exposure to automotive waste crankcase oil (WCO) were examined in 1-week-old mallard (Anas platyrhynchos) ducklings and pheasant (Phasianus colchicus) chicks. Treatment groups consisted of birds exposed to 0.5, 1.5, or 4.5% WCO, to 4.5% clean crankcase oil (CCO), or untreated controls. In both species,...
The role of the USFWS geographic information system in coastal decisionmaking
Robert Ader, Floyd O. Stayner
1983, Conference Paper, Auto-Carto 5: Proceedings: Environmental assessment and resource management
Unprecedented demand on coastal resources in the 1980's has generated a need for valid information and analyses to support wise management of the coastal zone. The National Coastal Ecosystems Team of the U.S. Fish and Wildlife Service recently implemented a geographic information system to enhance its ability to analyze and...
Use of pine nuts by grizzly and black bears in the Yellowstone area
Katherine C. Kendall
1983, Bears: Their Biology and Management (5) 166-173
The large seeds (pine nuts) of whitebark pine are commonly eaten in the spring (March-May) and fall (September-November) by grizzly and black bears in Yellowstone National Park and adjacent areas (Craighead and Craighead 1972, Blanchard 1978, Mealey 1980) and western Montana (Tisch 1961; J. Sumner and J. J. Craighead, unpubl....

Channels and valleys on Mars
Mars Channel Working Group
1983, GSA Bulletin (94) 1035-1054
The discovery of channels, valleys, and related features of aqueous origin on Mars is of profound importance in comparative planetology. Models of the evolution of planetary surfaces and atmospheres must be reconciled with the diversity, abundance, and origins of channels and valleys on Mars. The term “channel” is properly restricted...

Atmospheric deposition: Sample handling, storage, and analytical procedures for chemical characterization of event-based samples in North Dakota
R. L. Houghton, Mary E. Berger, Nancy Zander, Sandra K. Dutchek
1983, Water-Resources Investigations Report 83-4205
The North Dakota atmospheric-deposition network uses HASL-type collectors to sample wet and dry deposition on an event basis for analysis of 8 principal mineral, 3 nutrient, and 15 trace constituents. Comparison of the compositions of wet deposition collected in adjacent collectors sampled on weekly and event bases indicates that weekly...

Eolian sand bodies of the world
E. D. McKee
1983, Developments in Sedimentology (38) 1-25
This chapter examines the eolian sand bodies of the world. Analyses regarding grain size and sorting distribution at Great Sand Dunes indicate that the higher dunes contain much more fine-grained sand and much less medium-grained sand than do the lower dunes, and, in addition, they are definitely better sorted. Cross-stratification...

A tale of two plutons: petrographic and mineralogic constraints on the petrogenesis of the Red Lake and Eagle Peak plutons, central Sierra Nevada, California
J.H. Noyes, D. R. Wones, F.A. Frey
1983, Journal of Geology (91) 353-379
The two plutons are similar in age (K/Ar, 87-89 m.y.) and range in composition from granodiorite to granite. The Red Lake pluton is equigranular, has a locally greisened marginal zone, and shows only minor mineralogical and chemical zoning, whereas the Eagle Peak pluton is mineralogically, compositionally and texturally zoned, with...

Anaerobic oxalate degradation: Widespread natural occurrence in aquatic sediments
Richard L. Smith, Ronald S. Oremland
1983, Applied and Environmental Microbiology (46) 106-113
Significant concentrations of oxalate (dissolved plus particulate) were present in sediments taken from a diversity of aquatic environments, ranging from 0.1 to 0.7 mmol/liter of sediment. These included pelagic and littoral sediments from two freshwater lakes (Searsville Lake, Calif., and Lake Tahoe, Calif.), a hypersaline, meromictic,...
