Changes in wetland sediment elevation following major storms: implications for estimating trends in relative sea-level rise
Donald R. Cahoon
2003, Book chapter, Coastal Sediments ?03 Conference: Crossing Disciplinary Boundaries: proceedings of the 5th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes, Clearwater Beach, FL, May 18-23, Book of Abstracts
Hurricanes can be important agents of geomorphic change in coastal marshes and mangrove forests. Hurricanes can cause large-scale redistribution of sediments within the coastal environment resulting in sedimentation, erosion, disruption of vegetated substrates, or some combination of these processes in coastal wetlands. It has been proposed that such...
Synergistic effects of a combined exposure to herbicides and an insecticide in Hyla versicolor
L. Mazanti, D. W. Sparling, C. Rice, K. Bialek, C. Stevenson, B. Teels
Gregory L. Linder, Sherry K. Krest, Donald W. Sparling, Edward E. Little, editor(s)
2003, Book chapter, Multiple stressor effects in relation to declining amphibian populations
Combinations of the herbicides atrazine and metolachlor and the insecticide chlorpyrifos were tested under both laboratory and field conditions to determine their individual and combined effects on amphibian populations. In the lab Hyla versicolor tadpoles experienced 100% mortality when exposed to a high combination of the pesticides (2.0 mg/L...

Ecosystem-level consequences of migratory faunal depletion caused by dams
Mary C. Freeman, C. M. Pringle, E.A. Greathouse, B. J. Freeman
K.E. Limburg, J.R. Waldman, editor(s)
2003, Book chapter, Biodiversity, Status and Conservation of the World?s Shads
Humans have been damming rivers for millennia, and our more ambitious efforts over the past century have arguably altered river ecosystems more extensively than any other anthropogenic activity. Effects of damming on river biota include decimation of migratory fauna (e.g., diadromous and potamodromous fishes and crustaceans), lost fisheries, and...
White phosphorus at Eagle River Flats, Alaska: A case history of waterfowl mortality
Donald W. Sparling
David J. Hoffman, Barnett A. Rattner, G. Allen Burton Jr., John Cairns Jr., editor(s)
2003, Book chapter, Handbook of ecotoxicology, second edition
White phosphorus has a limited distribution in the environment because it only occurs where it has been directly used by humans. It is not transported aerially for any distance and, due to its density, has a limited ability to disperse through water. Therefore, it is not a contaminant of broad-scale...

Storms as agents of wetland elevation change: their impact on surface and subsurface sediment processes
Donald R. Cahoon
2003, Book chapter, Coastal Sediments ?03 Conference: Crossing Disciplinary Boundaries: proceedings of the 5th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes, Clearwater Beach, FL, May 18-23
Direct measures of the impact of major storms on wetland sediment elevation are rare. Recently developed techniques have enabled simultaneous, quantitative observations of surface and subsurface processes affecting sediment elevation. An analysis of ten wetland sites revealed the following patterns of sediment elevation change after storm passage: (1)...

Lead in the environment
Oliver H. Pattee, Deborah J. Pain
David J. Hoffman, Barnett A. Rattner, G. Allen Burton Jr., John Cairns Jr., editor(s)
2003, Book chapter, Handbook of ecotoxicology, second edition
Anthropogenic uses of lead have probably altered its availability and environmental distribution more than any other toxic element. Consequently, lead concentrations in many living organisms may be approaching thresholds of toxicity for the adverse effects of lead. Such thresholds are difficult to define, as they vary with the chemical and...
A critical look at national monitoring programs for birds and other wildlife species
J.R. Sauer
T. J. O'Shea, M.A. Bogon, editor(s)
2003, Book chapter, Monitoring trends in bat populations of the United States and Territories: Problems and Prospects
Concerns?about declines in numerous taxa have created agreat deal of interest in survey development. Because birds have traditionally been monitored by a variety of methods, bird surveys form natural models for development of surveys for other taxa. Here I suggest that most bird surveys are not appropriate models...
Animal species endangerment: The role of environmental pollution
Oliver H. Pattee, Valerie L. Fellows, Dixie L. Bounds
David J. Hoffman, Barnett A. Rattner, G. Allen Burton Jr., John Cairns Jr., editor(s)
2003, Book chapter, Handbook of ecotoxicology, second edition
Multiple factors contribute to the decline of species. Habitat destruction is the primary factor that threatens species. affecting 73 % of endangered species. The second major factor causing species decline is the introduction of nonnative species. affecting 68% of endangered species. Pollution and overharvesting were identified as impacting, respectively, 38...
The Chernobyl Nuclear Power Plant accident: ecotoxicological update
R. Eisler
David J. Hoffman, Barnett A. Rattner, G. Allen Burton Jr., John Cairns Jr., editor(s)
2003, Book chapter, Handbook of Ecotoxicology
The accident at the Chernobyl, Ukraine, nuclear reactor on 26 April 1986 released large amounts of radiocesium and other radionuclides into the environment, contaminating much of the northern hemisphere, especially Europe. In the vicinity of Chernobyl, at least 30 people died, more than 115,000 others were evacuated, and consumption...

A review of the role of contaminants in amphibian declines
Donald W. Sparling
David J. Hoffman, Barnett A. Rattner, G. Allen Burton Jr., John Cairns Jr., editor(s)
2003, Book chapter, Handbook of ecotoxicology, second edition
For the past decade, there has been growing concern about worldwide declines in amphibian populations,1,2 and a general phenomenon of declining populations was recognized in the mid-1990's. Subsequent research has validated this concern.3,4 These population declines have been defined either as decreases in numbers of individuals in an area or,...
Bioindicators of contaminant exposure and effect in aquatic and terrestrial monitoring
Mark J. Melancon
David J. Hoffman, Barnett A. Rattner, G. Allen Burton Jr., John Cairns Jr., editor(s)
2003, Book chapter, Handbook of ecotoxicology, second edition
Bioindicators of contaminant exposure presently used in environmental monitoring arc discussed. Some have been extensively field-validated and arc already in routine application. Included are (1) inhibition of brain or blood cholinesterase by anticholinesterase pesticides, (2) induction of hepatic microsomal cytochromes P450 by chemicals such as PAHs and PCBs, (3) reproductive...
