Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA MOLLUSCA BIVALVIA UNIONOIDA UNIONIDAE

Scientific Name: Elliptio producta
Species Authority: (Conrad, 1836)
Common Name(s):
English Atlantic Spike
Taxonomic Notes: The classification of the Atlantic Slope species of Elliptio is currently in a state of uncertainty. Johnson (1970) lumped many named taxa under a single name. Current research is finding many of these synonomized taxa to be valid species. This research is in progress and will result in the recognition of numerous additional taxa in this genus. Johnson (1970) placed this species in synonymy with Elliptio lanceolata, however Turgeon et al. (1998) list both as distinct species. No agreement has been reached on what this taxon is, therefore further study is needed.

A list of synonyms for this species can be found on The MUSSEL project web site (Graf and Cummings 2011).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2011
Date Assessed: 2011-07-22
Assessor(s): Cummings, K. & Cordeiro, J.
Reviewer(s): Böhm, M. & Collen, B.
Contributor(s): Dyer, E., Soulsby, A.-M., Whitton, F., McGuinness, S., De Silva, R., Milligan, H.T., Kasthala, G., Thorley, J., Herdson, R., McMillan, K. & Collins, A.
Justification:
Elliptio producta has been assessed as Least Concern due to the fairly widespread distribution along the Atlantic coast.This assessment may warrant a review in future if reductions in this species' range continue and is dependent upon taxonomic review. Further research regarding taxonomy and population trends, accompanied by monitoring or population trends, will help elicit future changes in population status.

Geographic Range [top]

Range Description: This species occurs on the Atlantic coast from the Savannah River north to the Roanoke River basin (Bogan et al. 2009). It is possibly extirpated from  the Ogeechee River system in Georgia (Sukkestad et al. 2006).
Countries:
Native:
United States (North Carolina)

Population [top]

Population: Although specific population information is lacking, this species is reported to be declining across its range and is uncommon where found (A. Bogan pers. comm. 2010).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species is known to occur in medium to large rivers, on sand and gravel substrate with current (A. Bogan pers. comm. 2010).
Systems: Freshwater

Threats [top]

Major Threat(s): Typical threats to freshwater systems include habitat degradation due to abstraction of water and pollution from urban, industrial and agricultural sources (A. Bogan pers. comm. 2010). Although these threats may be affecting the species on a local scale, they are unlikely to be impacting the global population.

Conservation Actions [top]

Conservation Actions: The conservation status of this species is currently under review by the North Carolina Wildlife Resources Commission. Williams et al. (in press) lists this species as vulnerable according to the AFS assessment. Further research regarding taxonomy and population trends, accompanied by monitoring of population trends, will help elicit future changes in population status.
