Selenium and heavy metals in San Francisco Bay diving ducks
Harry M. Ohlendorf, Roy W. Lowe, Paul R. Kelly, Thomas E. Harvey
1986, Journal of Wildlife Management (50) 64-70
We analyzed for selenium (Se) and heavy metals in greater scaups (Aythya marila) and surf scoters (Melanitta perspicillata) collected from southern San Francisco Bay in March and April 1982. There were no differences (P > 0.05) between species for liver concentrations of silver (Ag), mercury (Hg), or lead (Pb). Copper...
Interpretation and compendium of historical fire accounts in the Northern Great Plains
K.F. Higgins
1986, Resource Publication 161
This interpretation and compendium of historical fire accounts in the northern Great Plains provides resource managers with background information to justify the study or use of fire in management and provides a reference of historic fire accounts for those without ready access to major library collections. Historical accounts of fire...

Influence of weather and density on lamb survival of desert mountain sheep
Charles L. Douglas, David M. Leslie Jr.
1986, Journal of Wildlife Management (50) 153-156
This report concerns the effect of weather on lamb survival in desert mountain sheep (Ovis canadensis nelsoni) to 6-8 months of age in the River Mountains, Nevada, and how it integrates with density to limit the population. Regression analyses were used to examine relationships between lamb survival and weather variables...
Inclusion body disease of cranes: Comparison of pathologic findings in cranes with acquired vs. experimentally induced disease
J. C. Schuh, L. Sileo, Lynne M. Siegfried, Thomas M. Yuill
1986, Journal of the American Veterinary Medical Association (189) 993-996
Inclusion body disease of cranes was the cause of death in 17 immature and mature cranes of 5 different species in Wisconsin. A herpesvirus of unknown origin was the apparent cause. An isolate of this herpesvirus was used to experimentally infect 3 species of cranes. Macroscopic and microscopic lesions associated...
Review of the intensive culture of walleye fry
W. F. Krise, J. W. Meade
1986, Progressive Fish-Culturist (48) 81-89
Efficient intensive culture of larval walleyes (Stizostedion vitreum) may soon be realized due to results of research on larval development, culture environment, preferred food organisms, and feeding techniques. Larval behavior and morphology (developmental state) can be used as indicators for appropriate handling and feeding techniques. Certain environmental conditions such as...
Prairie restoration at the National Wildlife Health Laboratory (Wisconsin)
R. M. Windingstad
1986, Restoration & Management Notes (4) 72-72
The National Wildlife Health Laboratory (NWHL), U.S. Fish and Wildlife Service in Madison are in the process of a 7-ha prairie restoration project on their lands to create a microcosmic representation of presettlement Wisconsin. Visiting scientists, personnel from local schools and universities, and neighboring public will eventually be able to...
Immunoblot assay: a rapid and sensitive method for identification of salmonid fish viruses
P. E. McAllister, W. B. Schill
1986, Journal of Wildlife Diseases (22) 468-474
An immunoblot assay was used to identify the viruses of infectious pancreatic necrosis, infectious hematopoietic necrosis, and viral hemorrhagic septicemia. Viral antigen in infected cell culture supernatant was adsorbed onto nitrocellulose membrane or Whatman 541 filter paper and detected by enzyme-linked immunosorbent assay...
Urea cycle activity and arginine formation in rainbow trout (Salmo gairdneri)
Y. N. Chiu, R. E. Austic, G. L. Rumsey
1986, Journal of Nutrition (116) 1640-1650
Studies were conducted to determine whether rainbow trout fingerlings possess the ability to synthesize arginine via the urea cycle. Several urea cycle enzymes were detected in trout tissues. An experiment was conducted to determine whether the enzymes increase in response to starvation or in response to dietary protein level (0,...

B.R. Griffin
1986, Transactions of the American Fisheries Society (115) 641-642

Natural fire management in national parks
D.J. Parsons, D.M. Graber, J.K. Agee, J. W. van Wagtendonk
1986, Environmental Management (10) 21-24
An evolving understanding of ecological processes, together with ambiguities in National Park Service policy, have led to multiple interpretations of the role of management in our large natural area National Parks. National Park Service management policies must be dynamic and responsive to changes in scientific knowledge...
The use of stable isotopes in the study of photosynthesis in freshwater plants
Jon E. Keeley, Leonel Sternberg, Michael J. DeNiro
1986, Aquatic Botany (26) 213-223
The ratio of 13C/12C for photosynthetic tissues of 22 aquatic species was unrelated to photosynthetic pathway. In three aquatic environments CAM and non-CAM species were shown to have similar δ13C values. Although these CAM species derive up to half of their net carbon gain through dark fixation their δ13C values are similar to...
