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 boundary model: A geographical analysis of design and conservation of nature reserves
C. Schonewald-Cox, J.W. Bayless
1986, Biological Conservation (38) 305-322
It is widely recognised that nearly all parks and reserves are too small to protect their biological diversity. In response to this problem, we have been developing a multidisciplinary ‘boundary model’ that focuses upon the processes of exchange across the administrative edges of nature reserves. The model incorporates known dynamics...
[Book review] Fish immunology, edited by M. J. Manning and M. F. Tatner
B.R. Griffin
1986, Transactions of the American Fisheries Society (115) 641-642
Review of: Fish Immunology. Edited by M. J. Manning and M. F. Tatner. Academic Press, London. 1985. 374 pages. $32.50. Reviewed by B. R. Griffin, Fish Farming Experimental Station, U.S. Fish and Wildlife Service, Stuttgart, Arkansas 72160, USA....
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...
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...
Avian tuberculosis and salmonellosis in a whooping crane (Grus americana)
R. K. Stroud, C.O. Thoen, R. M. Duncan
1986, Journal of Wildlife Diseases (22) 106-110
The whooping crane has been the subject of intensive scientific study and management because it is an endangered species and has high public interest. Programs have been developed to identify critical habitat, to increase production through captive breeding, and in recent years, to use sandhill cranes (Grus canadensis) as surrogate...
Processing techniques for the production of an experimental computer-generated shaded-relief map
Damon D. Judd
1986, American Cartographer (13) 72-79
An experimental computer-generated shaded-relief map of a topographic quadrangle of Nome, Alaska, at 1:1,000,000 scale was created to demonstrate current capabilities of map production. This paper describes the techniques used to produce the map product. The data consisted of forty-eight 1° by 1° blocks of resampled digital elevation model (DEM) data....
Mapping nuclear craters on Enewetak Atoll, Marshall Islands
John C. Hampson
1986, Conference Paper, Proceedings International Symposium on Marine Positioning
In 1984, the U.S. Geological Survey conducted a detailed geologic analysis of two nuclear test craters at Enewetak Atoll, Marshall Islands, on behalf of the Defense Nuclear Agency. A multidisciplinary task force mapped the morphology, surface character, and subsurface structure of two craters, OAK and KOA. The field mapping techniques include...
Vegetation and terrain mapping in Alaska using Landsat MSS and digital terrain data
Mark Shasby, David M. Carneggie
1986, Photogrammetric Engineering and Remote Sensing (52) 779-786
During the past 5 years, the U.S. Geological Survey's (USGS) Earth Resources Observation Systems (EROS) Data Center Field Office in Anchorage, Alaska has worked cooperatively with Federal and State resource management agencies to produce land-cover and terrain maps for 245 million acres of Alaska. The need for current land-cover information...
High-energy nearshore processes
1986, Eos, Transactions, American Geophysical Union (67) 1369-1371
The problem of shoreline erosion has become a matter of much interest in the recent press. To some extent this interest has been driven by the slow rise in sea level that has lent an air of inevitabilty to matters. However, the discussions certainly become more focused by the approach...
Vegetation mapping of Nowitna National Wildlife Refuge, Alaska using Landsat MSS digital data
Stephen S. Talbot, Carl J. Markon
1986, Photogrammetric Engineering and Remote Sensing (52) 791-799
A Landsat-derived vegetation map was prepared for Nowitna National Wildlife Refuge. The refuge lies within the middle boreal subzone of north central Alaska. Seven major vegetation classes and sixteen subclasses were recognized: forest (closed needleleaf, open needleleaf, needleleaf woodland, mixed, and broadleaf); broadleaf scrub (lowland, alluvial, subalpine); dwarf scrub (prostrate...
A new view for resource managers
Robert H. Haas
1986, Rangelands (8) 99-102
In decades past, the rancher depended upon reports from cowboys to gather information he needed to make management decisions. Today, the vast open ranges of the cowboy era are mostly gone in the United States-fenced into pastures, paddocks, or fields that are now discrete management units. But fencing in the...
Land subsidence
T.L. Holzer
1986, Earthquakes & Volcanoes (USGS) (18) 131-137
In November 1966, sixty percent of Venice, Italy, is inundated by a storm surge that causes waters in the Venetian lagoon to rise more than 6 feet. On December 28, 1971, a janitor at the Washington Elementary School in Johnston City, Illinois, discovers sever cracking of the school. In January...
Earthquakes, January-February 1986
W. J. Person
1986, Earthquakes & Volcanoes (USGS) (18) 235-237
The first two months of the year were somewhat quiet seismically speaking. There were no major earthquakes (7.0-7.9) but one death was caused by an earthquake in Peru. In the United States a magntidue 4.9 earthquake in Ohio on January 31 caused some minor injuries and was felt in eleven states,...
Distribution and habitat of Nitellopsis obtusa (Characeae) in the Laurentian Great Lakes
Donald W. Schloesser, Patrick L. Hudson, S. Jerrine Nichols
1986, Hydrobiologia (133) 91-96
Nitellopsis obtusa, a macroalga (Characeae) native to Europe and Asia, was found in U.S. waters of the St. Clair-Detroit River system in 1983, thus extending the range of this taxon into the Laurentian Great Lakes about 850 km from the St. Lawrence River where it was first discovered...

H. Spall
1986, Earthquakes & Volcanoes (USGS) (18) 98-102
In late 1985 and early 1986 a comet was visible to the Earth that has been observed for over 2000 years. One of the most famous of celestial visitors, Comet Halley appeared last in 1910 and will not be seen again until the year 2061. the comet has been the...
Meteoroids and impact craters
Henry Spall
1986, Earthquakes & Volcanoes (USGS) (18) 84-89
On a clear night scores of meteoroids streak across the sky. they leave light paths we call meteors or shooting stars as the Earth is showered with debris from distant parts of the solar system. When these meteoroids hit the Earth (as meteorites) they range in size from pebbles to...
Predictive models in hazard assessment of Great Lakes contaminants for fish
Dora R. May Passino
1986, Conference Paper, Proceedings of the technology transfer conference, part b: water quality research
A hazard assessment scheme was developed and applied to predict potential harm to aquatic biota of nearly 500 organic compounds detected by gas chromatography/mass spectrometry (GC/MS) in Great Lakes fish. The frequency of occurrence and estimated concentrations of compounds found in lake trout (Salvelinus namaycush) and walleyes (Stizostedion vitreum vitreum)...
Volcanoes and atmospheres; catastrophic influences on the planets
S. W. Kieffer
1986, Earthquakes & Volcanoes (USGS) (18) 76-83
For a rare and brief instant in geologic time, we can imagine that the sulfurous, chromatic surface of Io (one of the satellites of Jupiter) lies quiet. Perhaps stars glisten brilliantly through the tenuous nigh sky. Here and there, thick icy fogs enshroud fumaroles where sulfur dioxide leaks from the...
