Abstract :	Increasing human populations and subsequent changes in land and water use are primary threats to freshwater habitats. Overall, the number of fish species and subspecies in North America requiring special management due to these threats has increased 45% during the past ten years. Most of the declines have been attributed to human factors including over-fishing, habitat changes, pollution and introductions of non-indigenous species. Spatial dynamics of riverine species are determined by relationships among numerous instream, riparian, and watershed processes. However, linkages among these elements and their relative and cumulative effects on stream communities are poorly understood. Furthermore, these processes may operate at different spatial scales, further complicating management efforts. Understanding the relations among these elements is vital for resource managers to accurately predict and effectively mitigate human-induced disturbances over large spatial scales.
