Effects of lowhead dams on the ephemeropterans, plecopterans, and trichopterans group in a north American River Effects of lowhead dams on the ephemeropterans, plecopterans, and trichopterans group in a north American River
We assessed the effects of lowhead dams on the EPT group (ephemeropterans, plecopterans, and trichopterans) by sampling habitat and macroinvertebiates monthly from November 2000 to October 2001 at eight gravel bars centered around two lowhead dams on the Neosho River, Lyon County, Kansas. Sites included a reference and treatment site upstream and downstream from each dam. Percent EFT was...

Back to the basics: Birmingham, Alabama, measurement and scale Back to the basics: Birmingham, Alabama, measurement and scale
Back to the Basics: Birmingham, Alabama is the fourth in a series of workshops that focus on teaching foundational map reading and spatial differentiation skills. It is the second published exercise from the Back to the Basics series developed by the Wetland Education through Maps and Aerial Photography (WETMAAP) Program (see Journal of Geography 103, 5: 226-230). Like its predecessor...

Acute toxicity value extrapolation with fish and aquatic invertebrates Acute toxicity value extrapolation with fish and aquatic invertebrates
Assessment of risk posed by an environmental contaminant to an aquatic community requires estimation of both its magnitude of occurrence (exposure) and its ability to cause harm (effects). Our ability to estimate effects is often hindered by limited toxicological information. As a result, resource managers and environmental regulators are often faced with the need to extrapolate across...

Amphibian Research and Monitoring Initiative (ARMI): A successful start to a national program in the United States Amphibian Research and Monitoring Initiative (ARMI): A successful start to a national program in the United States
Most research to assess amphibian declines has focused on local-scale projects on one or a few species. The Amphibian Research and Monitoring Initiative (ARMI) is a national program in the United States mandated by congressional directive and implemented by the U.S. Department of the Interior (specifically the U.S. Geological Survey, USGS). Program goals are to monitor changes in...

Influence of a Brazilian sewage outfall on the toxicity and contamination of adjacent sediments Influence of a Brazilian sewage outfall on the toxicity and contamination of adjacent sediments
The submarine sewage outfall of Santos (SSOS) is situated in the Santos Bay (São Paulo, Brazil) and is potentially a significant source of contaminants to the adjacent marine ecosystem. The present study aimed to assess the influence of SSOS on the sediment toxicity and contamination at Santos Bay. At the disposal site, sediments tended to be finer, organically richer and exhibited...

Light attenuation profiling as an indicator of structural changes in coastal marshes Light attenuation profiling as an indicator of structural changes in coastal marshes
To best respond to natural and human-induced stresses, resource managers and researchers require remote sensing techniques that can map the biophysical characteristics of natural resources on regional and local scales. The implementation of advanced measurement techniques would provide significant improvements in the quantity, quality, and timeliness of biophysical data useful in...
