PDF Application of environmental DNA for inventory and monitoring of aquatic species [More info]
Using genetic analysis of organic material found in aquatic environments it is possible to detect the presence of organisms without necessarily observing or capturing individuals. Explains terms, methods, and prospective utility of this approach.
PDF Assessment of aquatic macroinvertebrate communities in the Autauga Creek watershed, Autauga County, Alabama, 2009 [More info]
