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.
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.
Explains how critical information about dispersal and gene flow in sage-grouse populations can be obtained from the DNA coded in the sage-grouse feathers collected at their communal breeding grounds, which are called "leks".
Buffelgrass (Pennisetum ciliare) poses a problem in the deserts of the United States, growing in dense stands and introducing a wildfire risk in an ecosystem not adapted to fire. This report explains what we are doing to help mitigate its effects.
Describes the Conte Anadromous Fish Laboratory of the Leetown Science Center, which performs research directed towards restoration and protection of anadromous fish with lists of research projects and facilities.
The Fish Health Branch, Leetown Science Center, investigates fish health and disease issues associated with genetics, pathogens and environmental stress. With links to workshops, leaflets, and announcements relating for fish health.
