Why This Research is Important
The aquatic fauna of the southeastern US is among the most diverse worldwide, with many dozens of endemic species spread across 13 southeastern states. Many of these species, such as the eastern Brook trout are highly prized both for their sport and asthetc value but are under increasing pressure from land use and climate change. Particularly in coldwater streams, the composition and character of aquatic communities are among the most compelling indicators of ecosystem heath and vitality. The response of aquatic organisms to changes in water quality and their habitats can be directly linked to disturbances and land use changes, and knowledge of the role of disturbance in structuring aquatic communities will enable managers to implement protective measures and enhancements.
