Apparent digestibility coefficients of carbohydrates for white sturgeon Apparent digestibility coefficients of carbohydrates for white sturgeon
Apparent digestibility coefficients (ADCs) were determined for white sturgeons (Acipenser transmontanus) fed purified diets containing different carbohydrates. White sturgeons were fed, at a rate of 1.0% body weight!d, diets containing one of nine carbohydrates, and feces were collected by manual stripping following a 2‐week feeding period; chromium sesquioxide (Cr2O3) was used as an...

Canvasback ducks Canvasback ducks
Canvasbacks (Aythya valisineria) are unique to North America and are one of our most widely recognized waterfowl species. Unlike other ducks that nest and feed in uplands, diving ducks such as canvasbacks are totally dependent on aquatic habitats throughout their life cycle. Canvasbacks nest in prairie, parkland, subarctic, and Great Basin wetlands; stage during spring and fall on...

Habitat use at night by wintering American woodcock in coastal Georgia and Virginia Habitat use at night by wintering American woodcock in coastal Georgia and Virginia
Nocturnal habitats used by American woodcock (Scolopux minor) were studied using radio telemetry at two coastal wintering sites in Georgia (1982-84) and Virginia (1991-92). In Georgia, use of forested habitats at night was extensive while use of fields at night varied between years but generally was low. We found no difference in the probability of moving to a field at night among the...

Acid Rain Acid Rain
Although acid rain is fading as a political issue in the United States and funds for research in this area have largely disappeared, the acidity of rain in the Eastern United States has not changed significantly over the last decade, and it continues to be a serious environmental problem. Acid deposition (commonly called acid rain) is a term applied to all forms of atmospheric deposition...

Environmental factors affecting contaminant toxicity in aquatic and terrestrial vertebrates Environmental factors affecting contaminant toxicity in aquatic and terrestrial vertebrates
Environmental factors have long been demonstrated to influence the toxicity of pollutants to vertebrates. The vast majority of data has been derived from studies on fish, highly inbred laboratory rodents, and man.1,2 The magnitude and significance of these factors on toxicity has almost exclusively been elucidated in controlled experiments conducted in a laboratory setting. The...

Ecological and toxicological aspects of the partial meltdown of the Chernobyl nuclear power plant reactor Ecological and toxicological aspects of the partial meltdown of the Chernobyl nuclear power plant reactor
the partial meltdown of the 1000-MW reactor at Chernobyl, Ukraine, on April 26, 1986, released large amounts of radiocesium and other radionuclides into the environment, causing widespread radioactive contamination of Europe and the former Soviet Union.1-7 At least 3,000,000 trillion becquerels (TBq) were released from the fuel during the accident (Table 24.1), dwarfing, by orders of...

Agricultural drainwater effects on wildlife in central California Agricultural drainwater effects on wildlife in central California
In California's San Joaquin Valley and in numerous other agricultural areas in the western U.S., irrigation wastewater may accumulate in confined shallow aquifers, eventually rising to levels that adversely affect crops. To sustain long-term agricultural productivity in these regions, systems for the drainage and disposal of this subsurface wastewater must be installed.1,2 the drained...

Ecotoxicological damage from zinc smelting at Palmerton, Pennsylvania Ecotoxicological damage from zinc smelting at Palmerton, Pennsylvania
The two zinc smelters at Palmerton, PA emitted huge amounts of contaminants ( 260,000 t of Zn, 3,300 t of Cd, 6,800 t of Pb) to the air and severely damaged the forest on Blue Mountain. The high Zn concentrations in soil killed tree seedlings by inhibiting root elongation. The result was a forest with too few young trees. When natural stresses such as fire challenged the forest, the...
