The American Eel Anguilla rostrata has been excluded from many streams along the Atlantic slope of the USA because of movement barriers such as large dams. Loss of this formerly common top predator has the potential to influence many aspects of headw

In an ongoing effort to propose biologically protective nutrient criteria, we examined how total nitrogen (TN) and its forms were associated with macroinvertebrate communities in wadeable streams of Maryland. Taxonomic and functional metrics of an in

Urbanization is associated with substantial losses to stream biological diversity throughout the United States' mid-Atlantic. Stream restoration has been used to improve stream conditions and, in part, to ameliorate these losses. However, the relatio

We report the extirpation of Notropis bifrenatus (Bridle Shiner) from Maryland. This once widespread species has not been observed in this state since 1984 despite recent and extensive collection efforts in areas of historical occurrence. Based on th

Detailed analyses of habitat associations with rare species are typically constrained by limited sample size and the availability of habitat data. The dense spatial coverage of stream sampling by the Maryland Biological Stream Survey provides ample d

The distribution of imperiled stream fish, crayfish, salamander, and freshwater mussel species of Maryland streams in relation to urban land cover and nonnative species was investigated. Over the last 30 years, extinction or extirpation of 13 stream

Ecological thresholds have much potential as a tool to use for watershed management. Not all systems exhibit abrupt nonlinear responses, but the threshold concept is still useful for describing stressor responses or changes in state variables. For ex

We provide locality data for stream populations of Procambarus clarkii (Red Swamp Crawfish) in Maryland. This non-native species is now established in 14 watersheds in the Coastal Plain, including all watersheds where it was historically raised in aq

In 2002 and 2006, we conducted a survey of historical collection localities for Enneacanthus chaetodon (Blackbanded Sunfish) in Maryland. Blackbanded Sunfish were detected at only one of six historical localities. This locality consisted of 17 quarry

We examined the influence of landscape alteration and in situ stream habitat variables on brook trout Salvelinus fontinalis by using a landscape-scale, space-for-time substitution analysis and a smaller data set that tracked long-term changes in land
