To evaluate the status of native Salvelinus fontinalis (Brook Trout) on Pennsylvania's Laurel Hill, we sampled fish, assessed habitat, and documented water quality from 20 non-randomly selected headwater streams of northwest- and southeast-facing slo

Historically, Polyodon spathula (American Paddlefish) occurred within the Mississippi River Basin's large rivers, traversing hundreds of kilometers to complete their life cycle. However, populations declined in response to the installation of lock an

The spiny water flea (Bythotrephes longimanus), has successfully established populations in North American reservoirs and lakes, but little is known of its movement between lake and river systems. Here we document the first longitudinal movement of t

Over 4000 km of Pennsylvania's flowing waters and attendant ecosystems have been degraded by mine drainage to the exclusion of multiple designated uses. Both Acid Mine Drainage (AMD) and Net Alkaline Mine Drainage (NAMD) may result from coal extracti

To establish a baseline for assessment of climate change effects on populations of brook trout (Salvelinus fontinalis) in southwestern Pennsylvania, we surveyed a collective of headwater streams for fish population status and the development of annua

Connectivity throughout large riverine networks is often compromised by lock and dam (L/D) structures designed to facilitate year-round navigation. The resultant interruption of flow inhibits free passage of aquatic biota potentially isolating mainst

We assessed the effects of a series of navigational lock and dam (L/D) structures on the composition of their adjacent fish communities. The Allegheny and Monongahela Rivers of southwestern Pennsylvania contain 14 lock and dam installations, eight an
