The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) of Mississippi

  title={The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) of Mississippi},
  author={Robert L. Jones and William Todd Slack and Paul D. Hartfield},
Abstract Museum specimens and published literature records were examined to determine how many taxa of freshwater mussels of the family Unionidae occurred within the boundaries of the State of Mississippi. Eighty nine taxa (85 described species, two of which have two described subspecies within the state; two undescribed species) were found to be distributed over the 10 river drainages within the state. The greatest number of taxa was found in the Tombigbee River drainage (52), followed by the… 

Conservation implications of late Holocene freshwater mussel remains of the Leon River in central Texas

The results of this study provide an example of how zooarchaeological data can be used to evaluate mussel community change through time and provide evidence of range curtailment for threatened mussel species.


Abstract We present data on two prehistoric freshwater mussel (Unionidae) shell assemblages from Bayou Bartholomew, a free-flowing stream in Drew County, southeast Arkansas. The Taylor (3DR2) and

A Prehistoric Freshwater Mussel Assemblage from the Big Sunflower River, Sunflower County, Mississippi

Changes in the distributions of freshwater mussels (Unionoida: Hyriidae) in coastal south-eastern Australia and implications for their conservation status

A combined-evidence approach using published data, targeted surveys, historical records and a GIS-based, reach-scale measure of physical habitat quality was used to assess trends in the distributions of nine species in the south-eastern coastal region, finding that all species remain widely distributed and qualify as ‘least concern’ according to IUCN Red List criteria.

Prehistoric Molluscan Faunas of the Yazoo River, Mississippi, USA: Archaeological Perspectives for Modern Conservation

Though modern data are extremely limited for the Yazoo River, analysis revealed it once supported a diverse mussel community containing numerous species currently considered rare, endangered, or extinct in Mississippi.

Impoundments and the Decline of Freshwater Mussels: a Case Study of an Extinction Gradient

Abstract: One major factor leading to the imperilment of freshwater mussels ( Bivalvia, Unionidae) has been the large‐scale impoundment of rivers. We examined the distribution and abundance of
