An ecological problem-solving process for managing special-interest species
H.L. Short, S.C. Williamson
1988, Report, Management of amphibians, reptiles, and small mammals in North America: Proceedings of the symposium
We present a structured problem-solving process that can help resolve wildlife management issues. Management goals for wildlife species are expressed in terms of populations to be attained and maintained. Habitat quantity and quality necessary to achieve those population goals can then be determined. Proposed land-use changes are evaluated in terms...
Habitat requirements of New Mexico’s endangered salamanders
Cindy A. Ramotnik, N.J. Scott
1988, Report, Management of amphibians, reptiles, and small mammals in North America: Proceedings of the symposium
We measured habitat components for two state-listed endangered salamanders in New Mexico in 1986 and 1987. Both species are restricted to mesic environments within high-elevation, mixed coniferous forests. Steep slope and high elevation were the most useful variables for predicting the occurrence of Jemez Mountains salamanders and Sacramento Mountain salamanders,...
Monitoring wildlife habitat: A critique of approaches
Mel Schamberger
1988, Statistical Journal of the United Nations ECE (5) 303-313
Naturalists have long recognized that wildlife cannot exist in a natural state without adequate habitat. Habitat monitoring is an effort to monitor the physical conditions that provide life support for the species, given the underlying assumption that if the habitat is available the species will respond and fill that habitat...
Ducks Get Sick Too!
Ronald M. Windingstad, Cynthia J. Laitman
1988, Report
When it comes to getting sick, wild waterfowl—which include ducks, geese, and swans—are a lot like people. We are all vulnerable to a wide variety of diseases.Some diseases that affect waterfowl, such as avian botulism, have been recognized for many decades as a major cause of death. Others, such as...
Distribution, status, and traditional significance of the West Indian manatee Trichechus manatus in Venezuela
Thomas J. O'Shea, Martin Correa-Viana, Mark E. Ludlow, John G. Robinson
1988, Biological Conservation (46) 281-301
Aerial and interview surveys were conducted in 1986 to determine the current distribution, status, and traditional significance of the West Indian manatee Trichechus manatus in Venezuela. Aerial surveys provided just eight tentative sightings in 73 hours of searching. These discouraging results may have been due to poor visibility, small populations,...
Microhistological characteristics of selected aquatic plants of Florida, with techniques for the study of manatee food habits
L.A. Hurst, C.A. Beck
1988, Report, Biological Report
This study was initiated in 1978 to develop a technique of identifying and quantifying the digestive tract contents of Florida manatees (Trichechus manatus latirostris) and to serve as a manual for the identification and analysis of ingesta collected from manatee carcasses salvaged in Florida. This report includes key microhistological characters...

Changes in the morphometry of Las Vegas Wash and the impact on water quality
Richard A. Roline, James J. Sartoris
1988, Lake and Reservoir Management (4) 135-142
Las Vegas Wash, a natural wash east of Las Vegas, Nevada, carries stormwater, groundwater drainage, and sewage effluent from two sewage treatment plants to Lake Mean. Over 80 percent of the normal discharge of approximately 3.4 m3/s (120 ft3/s) consists of effluent from the City of Las Vegas and...
Recording strong motion studies
Roger D. Borcherdt
1988, Batiment International, Building Research and Practice (16) 87-92
Instruments now permit strong‐motion signals to be recorded over broader band widths, with wider dynamic range and signal resolution and with better data accessibility via computer. These advantages are utilized by the General Earthquake Observation System (GEOS) developed by the United States Geological Survey, by which a microcomputer‐controlled system provides...

Use of "specific" inhibitors in biogeochemistry and microbial ecology
Ronald S. Oremland, D.G. Capone
1988, Book chapter, Advances in microbial ecology
The above statement, although meant to be tongue in cheek, contains an essential truism: all work with inhibitors is inherently suspect. This fact has been known by biochemists for some time. However, use of chemical inhibitors of enzymic systems and membranes continues to be a common approach taken toward unraveling...

Determinants of breeding distributions of ducks
Douglas H. Johnson, J.W. Grier
1988, Wildlife Monographs (100)
The settling of breeding habitat by migratory waterfowl is a topic of both theoretical and practical interest. We use the results of surveys conducted annually during 1955-81 in major breeding areas to examine the factors that affect the distributions of 10 common North American duck species. Three patterns of settling...

The Detroit River, Michigan: an ecological profile
Bruce A. Manny, Thomas A. Edsall, Eugene Jaworski
1988, Biological Report 85(7.17)
A part of the connecting channel system between Lake Huron and Lake Erie, the Detroit River forms an integral link between the two lakes for both humans and biological resources such as fish, nutrients, and plant detritus. This profile summarizes existing scientific information on the ecological structure and functioning...
American wild celery (Vallisneria americana): Ecological considerations for restoration
C. E. Korschgen, W. L. Green
1988, Technical Report 19
The success of vegetation management programs for waterfowl is dependent on knowing the physical and physiological requirements of target species. Lakes and riverine impoundments that contain an abundance of the American wildcelery (Vallisneria americana ) have traditionally been favored by canvasbacks (Aythya valisineria ) and other waterfowl...
Applications of a simulation model to decisions in mallard management
L.M. Cowardin, Douglas H. Johnson, T.L. Shaffer, D. W. Sparling
1988, Fish and Wildlife Technical Report 17
A system comprising simulation models and data bases for habitat availability and nest success rates was used to predict results from a mallard (Anas platyrhynchos) management plan and to compare six management methods with a control. Individual treatments in the applications included land purchase for waterfowl production, wetland easement purchase,...

Relation of pH to toxicity of lampricide TFM in the laboratory
T.D. Bills, L. L. Marking, G.E. Howe, J.J. Rach
1988, Technical Report 53
In the control of larval sea lamprey (Petromyzon marinus ) with 3-trifluoromethyl-4-nitrophenol (TFM) in tributaries of the Great Lakes, occasional kills of other fishes have caused concern about the effects of the chemical on non-target organisms. Stream treatment rates have been based on previous application rates, alkalinity...
