Transport of chemical and microbial compounds from known wastewater discharges: Potential for use as indicators of human fecal contamination Transport of chemical and microbial compounds from known wastewater discharges: Potential for use as indicators of human fecal contamination
The quality of drinking and recreational water is currently (2005) determined using indicator bacteria. However, the culture tests used to analyze for these bacteria require a long time to complete and do not discriminate between human and animal fecal material sources. One complementary approach is to use chemicals found in human wastewater, which would have the advantages of (1)...

Effectiveness of egg immersion in aqueous solutions of thiamine and thiamine analogs for reducing early mortality syndrome Effectiveness of egg immersion in aqueous solutions of thiamine and thiamine analogs for reducing early mortality syndrome
Protocols used for therapeutic thiamine treatments in salmonine early mortality syndrome (EMS) were investigated in lake trout Salvelinus namaycush and coho salmon Oncorhynchus kisutch to assess their efficacy. At least 500 mg of thiamine HCl/L added to egg baths was required to produce a sustained elevation of thiamine content in lake trout eggs. Thiamine uptake from egg baths was not...

Assessing contaminant sensitivity of endangered and threatened aquatic species: Part II. chronic toxicity of copper and pentachlorophenol to two endangered species and two surrogate species Assessing contaminant sensitivity of endangered and threatened aquatic species: Part II. chronic toxicity of copper and pentachlorophenol to two endangered species and two surrogate species
Early life-stage toxicity tests with copper and pentachlorophenol (PCP) were conducted with two species listed under the United States Endangered Species Act (the endangered fountain darter, Etheostoma fonticola, and the threatened spotfin chub, Cyprinella monacha) and two commonly tested species (fathead minnow, Pimephales promelas, and rainbow trout, Oncorhynchus mykiss). Results were...

A rapid solid-phase extraction fluorometric method for thiamine and riboflavin in salmonid eggs A rapid solid-phase extraction fluorometric method for thiamine and riboflavin in salmonid eggs
A new method has been developed and successfully applied to the selective measurement of thiamine (nonphosphorylated), total thiamine (sum of thiamine, thiamine monophosphate [TMP], thiamine diphosphate [TDP], and thiamine triphosphate [TTP]), and potentially interfering riboflavin in acidic (2% trichloroacetic acid) extracts of selected salmonid and walleye egg samples. Acidic extracts...

Timing of seed dispersal generates a bimodal seed bank depth distribution Timing of seed dispersal generates a bimodal seed bank depth distribution
The density of soil seed banks is normally highest at the soil surface and declines monotonically with depth. Sometimes, for a variety of reasons, peak density occurs below the surface but, except in severely disturbed soils, it is generally true that deeper seeds are older. In seasonally dry habitats that develop deep soil cracks during the dry season, it is possible that some seeds...

Comparison of a novel passive sampler to standard water-column sampling for organic contaminants associated with wastewater effluents entering a New Jersey stream Comparison of a novel passive sampler to standard water-column sampling for organic contaminants associated with wastewater effluents entering a New Jersey stream
Four water samples collected using standard depth and width water-column sampling methodology were compared to an innovative passive, in situ, sampler (the polar organic chemical integrative sampler or POCIS) for the detection of 96 organic wastewater-related contaminants (OWCs) in a stream that receives agricultural, municipal, and industrial wastewaters. Thirty-two OWCs were identified...

Occurrence of antibiotics in water from 13 fish hatcheries, 2001-2003 Occurrence of antibiotics in water from 13 fish hatcheries, 2001-2003
A 2-year study of extensive and intensive fish hatcheries was conducted to assess the general temporal occurrence of antibiotics in aquaculture. Antibiotics were detected in 15% of the water samples collected during the 2001-2002 collection period and in 31% of the samples during the 2003 collection period. Antibiotics were detected more frequently in samples from the intensive...

Variations in pesticide tolerance: Chapter 16 Variations in pesticide tolerance: Chapter 16
A growing body of evidence suggests that a number of amphibian populations have declined in recent years. The cause of these population declines has been difficult to establish because in some instances only a single species is declining while sympatric species are thriving. This chapter discusses the results of research that has been conducted to determine the degree of variation...
