The use of live bait by anglers is an important vector of both aquatic and terrestrial invasive species. Bait-bucket introductions of invasive crayfishes, fishes, earthworms, pathogens, and other organisms have reduced biodiversity and altered ecosys

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

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

The Clean Water Act presents a daunting task for states by requiring them to assess and restore all their waters. Traditional monitoring has led to two beliefs: (1) ad hoc sampling (i.e., non-random) is adequate if enough sites are sampled and (2) mo

Biological indicators of stream condition are in use by water resource managers worldwide. The State of Maryland and many other organizations that use Indices of Biotic Integrity (IBIs) must determine when and how to refine their IBIs so that better

In this report, predictions of the species that were expected to occur at stream sites were generated and probable stressors to fish species that were predicted to occur but were absent were diagnosed. Predictions were generated based on the hierarch
