PDF An experiment to control nonnative fish in the Colorado River, Grand Canyon, Arizona [More info]
We removed non-native fish from a section of the river and the endangered native species humpback chub increased in abundance. But it is not yet clear that decreased competition explains the rebound in population.
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.
