Bordetella bronchiseptica associated with pulmonary disease in mountain voles (Microtus montanus)
Wayne I. Jensen, Ruth M. Duncan
1980, Journal of Wildlife Diseases (16) 11-14
Bordetella bronchiseptica was isolated from the lungs of all of six mountain voles (Microtus montanus) found dead or dying of pulmonary infection near the Bear River Research Station in northern Utah in January, 1973. The possibility of concomitant viral or mycoplasmal infection was not ruled out....
Reproductive success and nest attentiveness of mallard ducks fed Aroclor 1254
T. W. Custer, G. H. Heinz
1980, Environmental Pollution Series A: Ecological and Biological (21) 313-318
A dietary dosage of 25 ppm Aroclor 1254 fed to nine-month-old mallards Anas platyrhynchos for at least a month before egg-laying had no detrimental effect on reproductive success or nest attentiveness when hens were allowed to incubate their own eggs. The treatment caused no effect on number of hens laying, date of...

Visitor use patterns in Yosemite National Park
J. W. van Wagtendonk
1980, Journal of Travel Research (19) 12-17
After several years of dramatic increases, visitor use in Yosemite National Park has leveled off to an average of 2.4 million visits per year. Coincident with this decline in the growth rate, there have been some changes in visitation trends and patterns. Data collected in the park show that the...
The comparison of usage and availability measurements for evaluating resource preference
Douglas H. Johnson
1980, Ecology (61) 65-71
Modern ecological research often involves the comparison of the usage of habitat types or food items to the availability of those resources to the animal. Widely used methods of determining preference from measurements of usage and availability depend critically on the array of components that the researcher, often with a...
Effects of sea lamprey (Petromyzon marinus) control in the Great Lakes on aquatic plants, invertebrates and amphibians
P.A. Gilderhus, B. G. H. Johnson
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 1895-1905
The chemicals 3-trifluoromethyl-4-nitrophenol (TFM) or a combination of TFM and 2a??,5-dichloro-4a??-nitrosalicylanilide (Bayer 73) have been used to control the sea lamprey (Petromyzon marinus) in the Great Lakes for about 20 yr. These chemicals cause some mortalities of Oligochaeta and Hirudinea, immature forms of Ephemeroptera (Hexagenia sp.), and certain Trichoptera, Simuliidae,...

Epizootic of coccidiosis in free-flying lesser scaup (Aythya affinis)
R. M. Windingstad, M.E. McDonald, Louis N. Locke, S.M. Kerr, J.A. Sinn
1980, Avian Diseases (24) 1044-1049
A coccidiosis epizootic has occurred in lesser scaup (Aythya affinis) at Bluestem Reservoir in eastern Nebraska during the spring in each of three recent years: 1976-1978. Losses peaked during the period from mid-March through April. As much as 29% of the peak population of scaup using the reservoir died. Necropsies...
Salmonella meningoencephalomyelitis in a northern fur seal (Callorhinus ursinsus)
R. K. Stroud, M.E. Roelke
1980, Journal of Wildlife Diseases (16) 15-18
Salmonella enteritidis was isolated from the brain of a neonatal northern fur seal (Callorhinus ursinus) with gross and microscopic lesions of meningoencephalomyelitis. Microscopic lesions in the liver and lung suggested septicemia....
A quantitative analysis of naiad mollusks from the Prairie du Chien, Wisconsin dredge material site on the Mississippi River
M.E. Havlik, L. L. Marking
1980, Bulletin of American Malacological Union 30-34
The Prairie du Chien dredge material site contains about 100,000 cubic meters of material dredged from the East Channel of the Mississippi Riverin1976. Previous studies in that area suggested a rich molluscan fauna, but most studies were only qualitative or simply observations. Our study of this material was designed...
Wilderness permit compliance and validity
J. W. van Wagtendonk, J.M. Benedict
1980, Journal of Forestry (78) 399-401
In Yosemite National Park, 92 percent of the parties using back country areas had permits. Parties without permits were smaller in size and stayed for shorter periods of time. For all parties with permits, 62 percent made changes to their trips. Parties changing their trips in both time and...
Travel time variation on backcountry trails
J. W. van Wagtendonk, J.M. Benedict
1980, Journal of Leisure Research (12) 99-106
Numerous interrelated factors influence the travel times of hikers and riders on backcountry trails. This study sought to quantify those factors which were thought to be most important in affecting trail speeds. The travel times of 897 backpacking parties, 634 day hiking parties, and 111 riding parties were obtained from...
Effect of leaching on apparent digestion coefficients of feedstuffs for salmonids
R. R. Smith, M. C. Peterson, A. C. Allred
1980, Progressive Fish-Culturist (42) 195-199
Fecal excretions were collected from rainbow trout (Salmo gairdneri) in metabolism chambers. In this method of collection the daily excretion is suspended in about 1 L of water. Aliquots of the suspension were separated into solid and liquid fractions by settling, centrifuging, or filtering. Solid and liquid fractions and the...

Type C botulism losses at Horicon National Wildlife Refuge, 1978
R. M. Windingstad, R. M. Duncan, R.L. Drieslein
1980, Transactions of the Wisconsin Academy of Sciences, Arts, and Letters (68) 208-211
Avian botulism was responsible for the death of over 6,000 waterfowl at Horicon National Wildlife Refuge in Wisconsin in 1978. The outbreak occurred in early fall on a flooded 250 hectare fallow agricultural area on the northeast end of the refuge. The species most severely affected was the green-winged teal...
Development of sea lamprey (Petromyzon marinus) larvicides
John H. Howell, John J. Lech, John L. Allen
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 2103-2107
Larvicides are used to control sea lamprey (Petromyzon marinus) in the Great Lakes. These larvicides are useful because they are more toxic to sea lamprey than fish species found in the same habitat. The lampricides come from two classes of chemical compounds: (1) halonitrophenols, and (2) halonitrosalicylanilides. Selectivity of the...
The isolation of a herpes virus from captive cranes with an inclusion body disease
D. E. Docherty, D.J. Henning
1980, Avian Diseases (24) 278-283
A viral agent, identified as a herpesvirus and tentatively called 'inclusion body disease of cranes' (IBDC), was isolated from captive cranes involved in a die-off at the International Crane Foundation near Baraboo, Wisconsin. Preliminary animal susceptibility tests, based on experimental infections, suggested that White Pekin ducklings up to 17 days...

Investigations of the western segment of the Garlock fault were conducted at Castac Lake, Twin Lakes and Oak Creek Canyon. Studies were concentrated on the youngest fault trace as delineated by Clark (1973). Seismic refraction surveys, topographic surveys and geologic mapping provided positive evidence for fault offsets in Quaternary deposits...

The San Francisco River area includes about 950 square miles in Greenlee County in east-central Arizona. Water-resources development has been slight compared with that in many areas in Arizona. In 1978 about 500 acre-feet of water was diverted for irrigation from the San Francisco and Blue Rivers, and about 550...
