Interaction of flooding and salinity stress on baldcypress (Taxodium distichum) Interaction of flooding and salinity stress on baldcypress (Taxodium distichum)
Coastal wetlands of the southeastern United States are threatened by increases in flooding and salinity as a result of both natural processes and man-induced hydrologic alterations. Furthermore, global climate change scenarios suggest that, as a consequence of rising sea levels, much larger areas of coastal wetlands may be affected by flooding and salinity in the next 50 to 100 years. In...

Toxicity of fire retardant chemicals to aquatic organisms: Progress report Toxicity of fire retardant chemicals to aquatic organisms: Progress report
Fire retardants and suppressants used extensively in North America are often applied in environmentally sensitive areas that may contain endangered, threatened, or economically important plant and animal species. We conducted laboratory acute toxicity tests in both hard and soft waters with five commonly used fire control chemicals (Fire Trol LCG-R, Fire-Trol GTS-R, Phos-Chek D-75-F...

Use of behavioral avoidance testing in natural resource damage assessment Use of behavioral avoidance testing in natural resource damage assessment
Natural Resource Damage Assessment (NRDA) provisions established under federal and state statutes enable natural resource trustees to recover compensation from responsible parties to restore injured natural resources. Behavioral avoidance testing with fish has been used in NRDAs to determine injuries to natural resources and to establish restoration thresholds. In this manuscript we...

Processes of wetland loss in India Processes of wetland loss in India
Wetlands in India supply crucial human and animal needs such as drinking water, protein production, fodder, water purification, wildlife habitat, and flood storage. Increased appreciation of uses and threats is essential to protect wetlands where justified. Three quarters of India's population is rural, it places great demands on India's wetlands and losses continue to occur. This paper...

Pesticides in ground water: Do atrazine metabolites matter? Pesticides in ground water: Do atrazine metabolites matter?
Atrazine and atrazine-residue (atrazine + two metabolites - deethylatrazine and deisopropylatrazine) concentrations were examined to determine if consideration of these atrazine metabolites substantially adds to our understanding of the distribution of this pesticide in groundwater of the midcontinental United States. The mean of atrazine.residue concentrations was 53 percent greater...

Peak-flow frequency and extreme flood potential for streams in the vicinity of the Highland Lakes, central Texas Peak-flow frequency and extreme flood potential for streams in the vicinity of the Highland Lakes, central Texas
The Highland Lakes on the Colorado River are in an area periodically threatened by large storms and floods. Many storms exceeding 10 inches (in.) in depth have been documented in the area, including some with depths approaching 40 in. These storms typically produce large peak discharges that often threaten lives and property. The storms sometimes occur with little warning. Steep stream...
