Susan Colvin FishOther research interests include investigating how fish assemblages differ by stream type such as clear and blackwater streams, and seeking to understand what factors contribute to these assemblage differences.  I seek to better understand what environmental factors in different systems contribute to which fish species inhabit a system.  Additionally, I am interested in how anthropogenic influences alter these patterns.

I am also interested in what individual, species, and assemblage level data tells us about how biological communities are structured.  Simple biological relationships such as the species-area relationship or the addition of species as area increases are still not well understood.  I believe that projects on stream & lake fishes can inform biological understanding on many levels.
