Stream channel geomorphology influences mussel abundance in southern Appalachian streams, U.S.A.
-
We quantified freshwater mussel abundance and species richness and their physical habitat at 24 sites in eight streams in southern Appalachian catchments in 2000 and 2001. In addition, we modelled site-specific hydraulic parameters during summer baseflow and bankfull stages to estimate high- and low-discharge conditions, respectively.
Mussel abundance was related to stream geomorphology, whereas richness was related to stream size. Baseflow habitat parameters explained only minor variation in abundance or richness, and both measures were highly correlated with mean current velocity or stream size. Bankfull shear stress composed a relatively low proportion of overall mussel habitat variability, but it accounted for significant variation in abundance and richness. Mussel abundance was highly variable at sites subject to low-shear stress during spates, whereas abundance always was low at sites subject to high-shear stress. These data suggest that habitat conditions during floods, rather than those at summer baseflow, limit the abundance of mussels in Appalachian streams. These data also suggest that mussel abundance and assemblage structure may be sensitive to any changes in channel geomorphology and hydraulic conditions that might result from land use in the catchment.

Stream Classification Research Update
-
This presentation from Mark Anderson and Arlene Olivero Sheldon of The Nature Conservancy provides an update to the Steering Committee on this Appalachian LCC funded research project. A Stream Classification System for the Appalachian LCC is developing a hierarchical classification for stream and river systems and a GIS map for aquatic ecosystems. The study will include a report describing the methods used to evaluate and develop the classification system, a literature review of existing stream classifications, and a GIS stream data set.

Stream Impacts from Water Withdrawals in the Marcellus Shale Region
-
A new study from the Appalachian Landscape Conservation Cooperative (LCC) and Cornell University looks at how the region's surface freshwater supply – and the health of natural systems delivering this resource – have been impacted and may be altered in the coming years under increasing water withdrawals.
