Effects of Solute Transport Processes on In-Situ Denitrification for Nitrate Control in Ground Water
This paper discusses the effects of solute transport mechanisms on the effectiveness of biodenitrification in the subsurface environment. The only solute transport processes apparently...

Biodiversity in Riparian Communities and Watershed Management
Riparian communities are demonstrated to be regional centers of biodiversity and biomass. Examples are taken primarily from bird and lizard communities in the Southwest, since these vertebrates...
