Microsatellite markers for the endangered Roanoke logperch, Percina rex (Percidae) and their potential utility for other darter species Microsatellite markers for the endangered Roanoke logperch, Percina rex (Percidae) and their potential utility for other darter species
The Roanoke logperch (Percina rex Jordan and Evermann), an endangered fish, occurs in only six watersheds in the Roanoke and Chowan river drainages of Virginia, USA. The species' population genetic structure is poorly known. We developed 16 microsatellite markers that were reliably scorable and polymorphic P. rex. Markers were also screened in seven other darter species of the genus...

Projecting cumulative benefits of multiple river restoration projects: an example from the Sacramento-San Joaquin River system in California Projecting cumulative benefits of multiple river restoration projects: an example from the Sacramento-San Joaquin River system in California
Despite increasingly large investments, the potential ecological effects of river restoration programs are still small compared to the degree of human alterations to physical and ecological function. Thus, it is rarely possible to “restore” pre-disturbance conditions; rather restoration programs (even large, well-funded ones) will nearly always involve multiple small projects, each of...

Evidence for fish dispersal from spatial analysis of stream network topology Evidence for fish dispersal from spatial analysis of stream network topology
Developing spatially explicit conservation strategies for stream fishes requires an understanding of the spatial structure of dispersal within stream networks. We explored spatial patterns of stream fish dispersal by evaluating how the size and proximity of connected streams (i.e., stream network topology) explained variation in fish assemblage structure and how this relationship varied...

Integrating human impacts and ecological integrity into a risk-based protocol for conservation planning Integrating human impacts and ecological integrity into a risk-based protocol for conservation planning
Conservation planning aims to protect biodiversity by sustainng the natural physical, chemical, and biological processes within representative ecosystems. Often data to measure these components are inadequate or unavailable. The impact of human activities on ecosystem processes complicates integrity assessments and might alter ecosystem organization at multiple spatial scales. Freshwater

Spatiotemporal variability of stream habitat and movement of three species of fish Spatiotemporal variability of stream habitat and movement of three species of fish
Relationships between environmental variability and movement are poorly understood, due to both their complexity and the limited ecological scope of most movement studies. We studied movements of fantail (Etheostoma flabellare), riverweed (E. podostemone), and Roanoke darters (Percina roanoka) through two stream systems during two summers. We then related movement to variability in...
