Transferability of habitat suitability criteria: Response to comment
Response to comment by Williams, et al., 1999. North American Journal of Fisheries Management 19:623-625.
Freeman, Mary C.; Bowen, Z.H.; Bovee, K.D. Evaluation of generalized habitat criteria for assessing impacts of altered flow regimes on warmwater fishes
Assessing potential effects of flow regulation on southeastern warmwater fish assemblages is problematic because of high species richness and our poor knowledge of habitat requirements for most species. A previous attempt to reduce the complexity of describing habitat requirements for diverse assemblages defined five 'key habitat' types based on...
Bowen, Z.H.; Freeman, Mary C.; Bovee, K.D. Sampling effort and estimates of species richness based on prepositioned area electrofisher samples
Estimates of species richness based on electrofishing data are commonly used to describe the structure of fish communities. One electrofishing method for sampling riverine fishes that has become popular in the last decade is the prepositioned area electrofisher (PAE). We investigated the relationship between sampling effort and fish species...
Bowen, Z.H.; Freeman, Mary C. Transferability of habitat suitability criteria for fishes in warmwater streams
We developed habitat suitability criteria and tested their transferability for nine fishes inhabiting unregulated Piedmont and Coastal Plain streams in Alabama. Cr iteria for optimal habitat were defined as ranges of depth, velocity, substrate type and cover type for which a species' suitability index (proportional abundance divided by...
Freeman, Mary C.; Bowen, Z.H.; Crance, J.H. Two-dimensional habitat modeling in the Yellowstone/Upper Missouri River system
This study is being conducted to provide the aquatic biology component of a decision support system being developed by the U.S. Bureau of Reclamation. In an attempt to capture the habitat needs of Great Plains fish communities we are looking beyond previous habitat modeling methods. Traditional habitat modeling approaches have relied on one-...

McGregor, M. A.; Garner, J.T.; Bowen, Z.H. Evaluation of the mussel fishery in Wheeler Reservoir, Tennessee River
We evaluated the freshwater mussel fishery on Wheeler Reservoir, a 27,155-hectare mainstream impoundment of the Tennessee River in Alabama. During July 1991 through June 1992, we used a roving creel survey to conduct 285 interviews over 57 weekdays and 12 weekend days. Total harvest during the 12-month survey period was estimated to be 570 metric...
