Assemblage organization in stream fishes: Effects of environmental variation and interspecific interactions Assemblage organization in stream fishes: Effects of environmental variation and interspecific interactions
We assessed the relative importance of environmental variation, interspecific competition for space, and predator abundance on assemblage structure and microhabitat use in a stream fish assemblage inhabiting Coweeta Creek, North Carolina, USA. Our study encompassed a 10–yr time span (1983–1992) and included some of the highest and lowest flows in the last 58 years. We collected 16...

Evaluation of generalized habitat criteria for assessing impacts of altered flow regimes on warmwater fishes 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 quantitative descriptions of depth...

Transferability of habitat suitability criteria for fishes in warmwater streams 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. Criteria for optimal habitat were defined as those ranges of depth, velocity, substrate type, and cover type for which a species' suitability index (proportional abundance divided by proportional habitat availability, scaled from...
