Flexing Their Mussels - Restoration of the Cheoah River
-
The N.C. Wildlife Resources Commission's (NCWRC) mussel breeding program helps augment some declining populations and save others from extinction. There are about 17 places in the United States that grow freshwater mussels, but many of those are for research purposes. The Marion facility has held 17 of the approximately 50 species in North Carolina and has propagated seven species to bolster local populations throughout the state. Biologists Rachel Hoch, David Deaton and Peter Lamb are leading the effort in Marion with the help of the NCWRC's Aquatic Wildlife Diversity Program staff.

Floating the Conasauga or Just Another Day at the Office
-
No, all of our days are not this nice, but this one was a pretty good one! A beautiful July day, not too hot, clear blue sky and pretty good water conditions! The Conasauga is one of our favorite rivers to work! It originates in North Georgia, flows north into Tennessee, then flirts with the state line until finally turning back south into Georgia.

Freshwater Mussels of the Powell River, Virginia and Tennessee: Abundance and Distribution in a Biodiversity Hotspot
-
Historically, the Powell River had a diverse freshwater mussel fauna of 46 species. Various surveys conducted over the past century have recorded a decline in mussel densities and diversity throughout much of the river, due to historical and on-going anthropogenic impacts. In 2008 and 2009, random timed-search, systematic search, and quadrat sampling of 21 sites were completed to document species richness, relative abundance, density, and size-class structure of resident mussel populations. We recorded 19 species from 18 sites, including 5 endangered species during quadrat sampling efforts. he mussel fauna of the lower Powell River continues to represent one of the most diverse in the United States. Outside of the Powell River, only 2 or 3 populations remain for most of the listed species extant in the river. Given these qualities, the Powell River deserves recognition as a location for focused conservation efforts to protect its diverse mussel assemblage.

Full Proposal - A Stream Classification System for the Appalachian Landscape Conservation Cooperative
-
The goal of this project is to develop a hierarchical classification for stream and river systems within the Appalachian Landscape Conservation Cooperative (LCC). This classification system will identify and consistently map ecologically similar types of rivers and streams using a flexible hierarchical set of geomorphic and hydrologic variables deemed appropriate for classification by the participating states and relevant to the spatial scale of management.

Haywood Waterways Kids in the Creek
-
Kids in the Creek was created by the Tennessee Valley Authority and brought to Haywood County in 1997. The purpose is to expose 8th grade students to hands-on activities that raise awareness of the importance of clean water and the issues that could degrade water quality. The students rotate among four stations: the EnviroScape watershed model, water chemistry, fish, and benthic macroinvertebrates. At the fish station, the students collect data for a classroom exercise that ties everything together.

Human mining activity across the ages determines the genetic structure of modern brown trout (Salmo trutta L.) populations
-
Humans have exploited the earth’s metal resources for thousands of years leaving behind a legacy of toxic metal contamination and poor water quality. The southwest of England provides a well-defined example, with a rich history of metal mining dating to the Bronze Age. Mine water washout continues to negatively impact water quality across the region where brown trout (Salmo trutta L.) populations exist in both metal-impacted and relatively clean rivers. We used micro- satellites to assess the genetic impact of mining practices on trout populations in this region. Our analyses demonstrated that metal-impacted trout populations have low genetic diversity and have experienced severe population declines. Metal-river trout populations are genetically distinct from clean-river populations, and also from one another, despite being geographically proximate. Using approximate Bayesian computation (ABC), we dated the origins of these genetic patterns to periods of intensive mining activity. The historical split of contemporary metal-impacted populations from clean-river fish dated to the Medieval period. Moreover, we observed two distinct genetic populations of trout within a single catchment and dated their divergence to the Industrial Revolution. Our investigation thus provides an evaluation of contemporary population genetics in showing how human-altered landscapes can change the genetic makeup of a species.
