Navigation: traveling the water highways!
Marion Fisher, Stephen Vandas, Frank Farrar (artist)
1996, Report
NAVIGATION is travel or transportation over water. Many different kinds of boats and ships are used on rivers and oceans to move people and products from one place to another. Navigation was extremely important for foreign and domestic trade and travel in the early days of our country before cars,...

P.H. Albers, D. E. Green, C. J. Sanderson
1996, Journal of Wildlife Diseases (32) 468-485
A feeding study with mallard ducks (Anas platyrhynchos) was conducted during March to July 1988 in Laurel, Maryland (USA), to identify diagnostic criteria for selenium toxicosis in birds. One-year-old male mallards in groups of 21 were fed diets containing 0, 10, 20, 40,...

Effects of boron and selenium on mallard reproduction and duckling growth and survival
T.R. Stanley Jr., G. J. Smith, D. J. Hoffman, G. H. Heinz, R. Rosscoe
1996, Environmental Toxicology and Chemistry (15) 1124-1132
Boron (B) and selenium (Se) sometimes occur together in high concentrations in the environment and can accumulate in plants and invertebrates consumed by waterfowl. One hundred twenty-six pairs of breeding mallards (Anas platyrhynchos) were fed diets supplemented with B (as boric acid) at 0, 450, or 900 ppm, in...
Wolf management in the 21st century: From public input to sterilization
L.D. Mech, S. H. Fritts, M.E. Nelson
1996, Journal of Wildlife Research (1) 195-198
Human-population increase and land development portend increasing conflict with large predators. Concurrently, changes and diversification of human attitudes are bringing increased disagreement about wildlife management. Animal-rights advocacy resulting from urbanization of human populations conflicts with traditional wildlife management. These forces focus more on wolves than on other...

Potential for water-quality degradation of interconnected aquifers in west-central Florida
P. A. Metz, D. L. Brendle
1996, Water-Resources Investigations Report 96-4030
Thousands of deep artesian wells were drilled into the Upper Floridan aquifer in west-central Florida prior to well-drilling regulations adopted in the 1970's. The wells were usually completed with a short length of casing through the unconsolidated sediments and were left open to multiple aquifers containing water of varying quality....

A series of freshwater subsurface injection, storage, and recovery tests were conducted at an injection-well site near Lake Okeechobee in Okeechobee County, Florida, to assess the recoverability of injected canal water from the Lower Floridan aquifer. At the study site, the Lower Floridan aquifer is characterized as having four local,...
Population structure of red-cockaded woodpeckers (Picoides borealis) in south Florida: RAPDs revisited
Susan M. Haig, R. Bowman, Thomas D. Mullins
1996, Molecular Ecology (5) 725-734
Six south Florida populations of the endangered red-cockaded woodpecker (Picoides borealis) were sampled to examine genetic diversity and population structure in the southernmost portion of the species' range relative to 14 previously sampled populations from throughout the species range. Random amplified polymorphic DNA (RAPD) analyses were used to evaluate the...
Recycling of nonmetallics
T.D. Kelly
1996, Natural Resources Research (5) 269-276
The first factor determining recyclability is the composition of the material itself. Metals, for example, can be reused with little or no loss in quality. Paper and rubber, by this criterion, are less recyclable. Each time paper is recycled, some cellulose fibers are broken. Shorter fibers can mean weaker paper...
Use of archaeology to date liquefaction features and seismic events in the New Madrid seismic zone, Central United States
Martitia P. Tuttle, Robert H. Lafferty III, Margaret J. Guccione, Eugene S. Schweig III, N. Lopinot, Robert F. Cande, Kathleen Dyer-Williams, Marion Haynes
1996, Geoarchaeology - An International Journal (11) 451-480
Prehistoric earthquake-induced liquefaction features occur in association with Native American occupation horizons in the New Madrid seismic zone. Age control of these liquefaction features, including sand-blow deposits, sand-blow craters, and sand dikes, can be accomplished by extensive sampling and flotation processing of datable materials as well as archaeobotanical analysis of...

Ground-water and surface-water relations along the Mojave River, southern California
Gregory C. Lines
1996, Water-Resources Investigations Report 95-4189
The Mojave River and the associated floodplain aquifer are important water supplies in the Mojave Desert of Southern California. The river and aquifer, in many areas, are in excellent hydraulic connection, and when flow conditions change in one, the other almost always is affected.To better understand these relations, records of...
Kangaroo rat bone compared to white rat bone after short-term disuse and exercise
E. Muths, O. J. Reichman
1996, Comparative Biochemistry and Physiology, Part A: Physiology (114) 355-361
Kangaroo rats (Dipodomys ordii) were used to study the effects of confinement on mechanical properties of bone with a long range objective of proposing an alternative to the white rat model for the study of disuse osteoporosis. Kangaroo rats exhibit bipedal locomotion, which subjects their limbs to substantial accelerative forces...

Donald D. MacDonald, R. Scott Carr, Fred D. Calder, Edward R. Long, Christopher G. Ingersoll
1996, Ecotoxicology (5) 253-278
The weight-of-evidence approach to the development of sediment quality guidelines (SQGs) was modified to support the derivation of biological effects-based SQGs for Florida coastal waters. Numerical SQGs were derived for 34 substances, including nine trace metals, 13 individual polycyclic aromatic hydrocarbons (PAHs), three groups of PAHs, total polychlorinated biphenyls (PCBs),...

Christopher P. Onuf
1996, Marine Ecology Progress Series (138) 219-231
A brown tide caused by a very dense bloom of an as yet undescribed species of the new class Pelagophyceae was first reported in upper Laguna Madre, Texas, USA, in June 1990 and has been there continuously through December 1995. No change in response to reduced light was evident in...
Extremes in ecology: Avoiding the misleading effects of sampling variation in summary analyses
William A. Link, John R. Sauer
1996, Ecology (77) 1633-1640
Surveys such as the North American Breeding Bird Survey (BBS) produce large collections of parameter estimates. One's natural inclination when confronted with lists of parameter estimates is to look for the extreme values: in the BBS, these correspond to the species that appear to have the greatest changes in population...
Magma transport and metasomatism in the mantle; a critical review of current geochemical models; reply
Jane E. Nielson, Howard G. Wilshire
1996, American Mineralogist (81) 760-765
Navon et al. (1996) demonstrated that the Navon and Stolper (1987) model can be formulated to reproduce a pattern of light-ion lithophile trace element (LIL) enrichments produced by a single, small-scale metasomatic process recorded in a composite xenolith from Dish Hill, California (Nielson et al. 1993). The Navon and Stolper...
