The importance of biological surveys in managing public lands in the western United States
Michael A. Bogan, R. B. Finley Jr., S.J. Petersburg
1988, Report, Proceedings of the symposium on management of amphibians, reptiles, and small mammals in North America
Despite previous studies, incomplete knowledge of the mammalian fauna of many national parks hinders our ability to understand the consequences of either management actions of natural disasters to such preserves. Faunal losses have occurred and can be expected to continue (Newmark 1986a, 1986b). our studies in and near Dinosaur National...
An overview of a habitat suitability index model for moose: Lake Superior region
A.W. Allen, J.W. Terrell, P.A. Jordan
1988, Alces (24) 118-125
A three-day workshop was held to develop a model for evaluation of moose habitat in the Lake Superior region. The ultimate goal of the workshop was to provide planning tools to enhance habitat management for moose and maximize the integration of those management objectives with silvicultural goals. An abstract of...
Patterns of relative diversity within riparian small mammal communities, Platte River Watershed, Colorado
T.E. Olson, Fritz L. Knopf
1988, Report, Management of amphibians, reptiles, and small mammals in North America: Proceedings of the symposium
Relative diversity within and between small mammal assemblages of riparian and upland vegetation was evaluated at 6 study areas across an elevational gradient. In contrast to avian diversity analyses conducted at the same sites, species richness, relative diversity, and faunal similarity of small mammals were greater among upland rather than...
Asynchronous hatching and food limitation: A test of Lack's hypothesis
Susan Knight Skagen
1988, The Auk (105) 78-88
Lack's (1954, 1968) hypothesis that asynchronous hatching of altricial birds is an adaptive response to unpredictable food shortages during the breeding season was examined in the highly granivorous Zebra Finch (Poephila guttata). I compared growth and survival of nestlings in asynchronous and artificially created synchronous broods reared under food-limited and...
Proceedings of a workshop on the development and evaluation of habitat suitability criteria: A compilation of papers and discussions presented at Colorado State University, Fort Collins, Colorado, December 8-12, 1986
Ken Bovee, J.R. Zuboy
1988, Book
The development of reliable habitat suitability criteria is critical to the successful implementation of the Instream Flow Incremental Methodology (IFIM), or any other habitat based evaluation technology. It is also a fascinating topic of research, for several reasons. First, the “science” of habitat quantification is relatively young. Descriptions of habitat...

Douglas-fir forests in the Oregon and Washington Cascades: relation of the herpetofauna to stand age and moisture
R. Bruce Bury, P.S. Corn
1988, Report, Management of amphibians, reptiles, and small mammals in North America
Pitfall traps effectively sampled amphibians but not reptiles in Douglas-fir (Pseudotsuga menziesii) forests. The abundance of only one amphibian species varied across an age gradient or a moisture gradient. Salamanders and frogs that breed in ponds or streams were captured in large numbers in some stands, likely due to the...
Mineral resources of the U.S. Atlantic continental margin
Stanley R. Riggs, Frank T. Manheim
1988, Book chapter, The Atlantic Continental Margin
Most geologic materials may be usable resources in some form and at some time, whether it be for general land fill and aggregate, beach replenishment, construction material, or as a source of metals and fuels. Thus, most natural materials occurring within the Atlantic continental margin are resources, defined as “materials,...

Small mammal response to the introduction of cattle into a cottonwood floodplain
F. B. Samson, F.L. Knopf, L.B. Hass
1988, Report, Management of amphibians, reptiles, and small mammals in North America: Proceedings of the symposium
Few differences between pastures in small mammal communities were evident prior to grazing, 1 month following grazing, and no differences in number or distribution of small mammals were observed 5 months following grazing. Each small mammal species exhibited different habitat use compared to availability and few habitat variables differed on...
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

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...
