Extensive artificial waterways have replaced natural wetlands and created new estuarine habitats on the southernQueensland coast, Australia. Economically important fish species found in adjacent natural wetlands of mangrove, saltmarsh and seagrass also occur in the artificial waterways. Stable isotope analyses (dC, dN)were used to test whether the relative importance of basal sources of energy ...
Inland waterways are large-scale networks used principally for navigation. Even if the transport planning is an important issue, the water resource management is a crucial point. Indeed, navigation is not possible when there is too little or too much water inside the waterways. Hence, the water resource management of waterways has to be particularly efficient in a context of climate change and ...
Erratum: “Nutrient Pollution: A Persistent Threat to Waterways” The November 2014 News article “Nutrient Pollution: A Persistent Threat to Waterways” [Environ Health Perspect 122:A304–A309; http://dx.doi.org/10.1289/ehp.122-A304] accidentally used the same map to depict both phosphorus and nitrogen pollution in U.S. waterways. In addition, the caption for the phosphorus map incorrectly stated t...
Artificial residential waterways are now widespread in the world’s estuaries. We used the global mapping tool, Google Earth, to determine that there are nearly 4000 linear km of artificial waterways globally, covering an area of 270 km2. Residential waterways constructed as open, flow-through canal estates are at their greatest extent in North America (77% of global linear extent), where system...
Urban waterways represent a natural reservoir of antibiotic resistance which may provide a source of transferable genetic elements to human commensal bacteria and pathogens. The objective of this study was to evaluate antibiotic resistance of Escherichia coli isolated from the urban waterways of Milwaukee, WI compared to those from Milwaukee sewage and a clinical setting in Milwaukee. Antibioti...
Pathogen Transmission Routes Research Program, describing pathogen pathways from farm animals to water bodies and measures that can reduce or prevent through the deposition of faeces by grazing animals directly into waterways in New Zealand. Bridging of streams intersected by farm raceways is an appropriate mitigation measure to prevent direct deposition during herd crossings, whilst fencing st...
