Abstract:
|
Monitoring streams and rivers over vast spatial extents is essential for management of freshwater resources. Monitoring goals are to quantify aquatic population status and trend as well as to uncover correlations between aquatic status and human activities. However, understanding the effects of human actions on aquatic communities is hindered by co-varying anthropogenic and abiotic drivers. In this paper, we quantify underlying correlations between human actions, such as agricultural land-use, and environmental gradients that also drive fish and invertebrate population performance. We analyze and compare existing data from the Pacific Northwest USA and central Europe. We conclude by quantifying impacts of these underlying correlations on our ability to detect relationships of interest and provide guidance for how monitoring programs could be designed to minimize these impacts.
