Current Research

I am currently engaged in research on stream fish ecology and conservation and on a comprehensive three volume book synthesizing our knowledge of freshwater fishes of North America.The stream research encompasses spatial scales ranging from individual habitat units such as pools to entire watersheds to drainage basins.The research is located primarily in Gulf Coastal Plain streams. Work on stream fish ecology includes studies of local colonization and extinction dynamics in relation to environmental variability,  recovery of stream fishes after disturbance, and the structure, stability, habitat interrelationships, and co-occurrence dynamics of warmwater fish communities. Conservation research includes assessments of aquatic biodiversity and examining association of biological and landscape-scale factors with imperilment of aquatic organisms.
