The Effects Of A Reservoir On Genetic Isolation In Two Species Of Darters, Kerstin Lindsay Edberg

Masters Theses & Specialist Projects

The addition of dams into a riverine system causes a wide range of changes (i.e., sedimentation, erosion, thermal) to the river as well as to the fish assemblages of that river. Although there have been many studies documenting the changes that occur to the fish assemblages in the impounded river, there have been fewer studies examining the effects of a reservoir on the fish inhabiting the tributaries upstream of the impoundment. One possible impact of a reservoir could be to act as a barrier to fish migration between streams.
To determine if reservoirs restrict migration, the genetic diversity of two …
