WALTERS, DAVID M., F. B. DANIEL, M. B. GRIFFITH, AND F. H. MCCORMICK. EFFECT OF FLOW REGIME ON FISH-HABITAT RELATIONSHIPS IN A MID-WESTERN RIVER. Presented at American Fisheries Society, Anchorage, AL, September 11 - 15, 2005.
Impact/Purpose:
The goal of this research is to develop methods and indicators that are useful for evaluating the condition of aquatic communities, for assessing the restoration of aquatic communities in response to mitigation and best management practices, and for determining the exposure of aquatic communities to different classes of stressors (i.e., pesticides, sedimentation, habitat alteration).
Description:
Numerous studies have shown interrelationships among stream fishes, habitat and land use, but it is unclear how flow regime affects these relationships. We hypothesized that habitat would better predict fishes in streams with stable flows. Habitat should be less predictive in unstable regimes due to the overriding importance of episodic droughts. We tested this hypothesis with data collected over five years in thirty-five tributaries of the Little Miami River in Ohio.
