Sodium cyanide hazards to fish and other wildlife from gold mining operations Sodium cyanide hazards to fish and other wildlife from gold mining operations
Highly toxic sodium cyanide (NaCN) is used increasingly by the international mining community to extract gold and other precious metals through milling of high grade ores and heap leaching of low grade ores. Of the 98 million kg cyanide (CN) consumed in North America in 1989, about 80% was used in gold mining (Knudson 1990). In Canada, more than 90% of the mined gold is extracted from...

Snake species of the world: A taxonomic and geographic reference. v. 1 Snake species of the world: A taxonomic and geographic reference. v. 1
Given the absence of a current source on snake diversity and nomenclature and the expressed global need to understand better the diversity of our biota, we think that a catalogue of the world snake fauna complete with synonymies at the familial, generic, and specific levels is essential. We provide that here beginning with publication of the first volume. This compendium will facilitate

Estimation of tiger densities in India using photographic captures and recaptures Estimation of tiger densities in India using photographic captures and recaptures
The tiger (Panthera tigris) is an endangered, large felid whose demographic status is poorly known across its distributional range in Asia. Previously applied methods for estimating tiger abundance, using total counts based on tracks, have proved unreliable. Lack of reliable data on tiger densities not only has constrained our ability to understand the ecological factors shaping...

Are adult nonbreeders prudent parents? The kittiwake model Are adult nonbreeders prudent parents? The kittiwake model
Understanding evolutionary consequences of intermittent breeding (nonbreeding in individuals that previously bred) requires investigation of the relationships between adult breeding state and two demographic parameters: survival probability and subsequent breeding probability. One major difficulty raised by comparing the demographic features of breeders and nonbreeders as estimated from...

Mortality and survival of white-tailed deer Odocoileus virginianus fawns on a north Atlantic coastal island Mortality and survival of white-tailed deer Odocoileus virginianus fawns on a north Atlantic coastal island
Mortality and survival of white-tailed deer Odocoileus virginianus fawns (N = 29) were studied from birth to one year of age during 1991–95 on Mount Desert Island (MDI), Maine, where deer hunting is prohibited, coyotes Canis latrans have become recently established, and protected U.S. National Park lands are interspersed with private property. The rate of predator-caused mortality was 0...

Relation of lead exposure to sediment ingestion in mute swans on the Chesapeake Bay, USA Relation of lead exposure to sediment ingestion in mute swans on the Chesapeake Bay, USA
Although wildlife risk assessments are generally based on the accumulation of environmental contaminants through food chains, wildlife may also ingest contaminants incidentally with sediment. Forty-two mute swans (Cygnus olor) were collected from unpolluted portions of central Chesapeake Bay, Maryland, USA, in spring 1995, and their intestinal digesta were analyzed for 13 metals...

Estimation of temporal variability of survival in animal populations Estimation of temporal variability of survival in animal populations
Temporal variation of demographic characteristics for animal populations is of interest to both ecologists and biological modelers. The standard deviation of a series of estimated parameter values (e.g., estimated population size) or some function thereof (e.g., log of the estimated parameters) is commonly used as a measure of temporal variability. These measures of temporal variation...
