A total of 18 species were represented by live individuals and/or empty shell. No live individuals or empty shells of the northern riffleshell or rayed bean (Villosa fabalis) were found. Two empty shells of the state threatened wavy-rayed lampmussel (Lampsilis fasciola) were found at Site 28 off Grassy Island. The most abundant unionids found live were mapleleaf (Quadrula quadrula), threeridge (Amblema plicata), and lilliput (Toxolasma parvus). The occurrence of live lilliput mussels at the Fermi/Swan Creek area is of special note because there are relatively few known populations in Michigan. The prevalence of silt tolerant species and the high proportions of silt found at a majority of sites provides evidence that substrate composition is a factor contributing to the decline and/or exclusion of listed unionids in the DRIWR. Live zebra mussels were found attached to live unionid mussels at two sites in the Berenholz area and two sites in the Fermi/Swan Creek area. The presence of live zebra mussels attached to live uninoinds and recently dead unionid shells indicate a history impact at sites surveyed in the DRIWR. Sites 31 and 32 off Sugar Island may have the most potential to support northern riffleshell and other listed unionid species of the sites included in this study.

Krebs Department of Biological, Geological and Environmental Sciences Cleveland State University Cleveland, Ohio, USA 44115 September 2015 (Revised from 2009) 2 Atlas of the Freshwater Mussels (Unionidae) (Class Bivalvia: Order Unionoida) Recorded at the Old Woman Creek National Estuarine Research Reserve & State Nature Preserve, Ohio, and surrounding watersheds Acknowledgements I thank Dr. David Klarer for providing the stimulus for this project and Kristin Arend for a thorough review of the present revision. The Old Woman Creek National Estuarine Research Reserve provided housing and some equipment for local surveys while research support was provided by a Research Experiences for Undergraduates award from NSF (DBI 0243878) to B. Michael Walton, by an NOAA fellowship (NA07NOS4200018), and by an EFFRD award from Cleveland State University. Numerous students were instrumental in different aspects of the surveys: Mark Lyons, Trevor Prescott, Erin Steiner, Cal Borden, Louie Rundo, and John Hook. Specimens were collected under Ohio Scientific Collecting Permits 194 (2006), 141 (2007), and 11-101 (2008). The Old Woman Creek National Estuarine Research Reserve in Ohio is part of the National Estuarine Research Reserve System (NERRS), established by section 315 of the Coastal Zone Management Act, as amended.

  • Wavy-Rayed Lampmussel
    Species Status Assessment Class: Bivalvia Family: Unionidae Scientific Name: Lampsilis fasciola Common Name: Wavy-rayed lampmussel Species synopsis: Lampsilis fasciola belongs to the subfamily Ambleminae and the tribe Lampsilini, which includes 17 extant and 6 likely extirpated New York species of the genera Actinonaias, Epioblasma, Lampsilis, Leptodea, Ligumia, Obovaria, Potamilus, Ptychobranchus, Toxolasma, Truncilla, and Villosa (Haag, 2012; Graf and Cummings, 2011). L. fasciola is mainly found in and around riffle areas of clear, hydrologically stable, fast moving water (Watters et al., 2009). Since 1970, L. fasciola has been found in six New York waterbodies. Historically, it has been collected in the Erie, Western Lake Ontario, and Lower Genesee basins (Strayer & Jirka, 1997). L. fasciola no longer considered abundant in any New York location, however they are most commonly found in the Allegheny River and its tributaries (The Nature Conservancy, 2009). With a state rank of “critically imperiled,” L. fasciola is listed as threatened in New York State, although it is secure throughout its range (NatureServe, 2013). In North America, approximately ⅔ to ¾ of native mussel species are extinct, listed as endangered or threatened, or are in need of conservation status (Williams et al. 1993; Stein et al.2000). While population trends in New York are unknown, it is assumed that they too are declining, due to a myriad of environmental stressors. 1 Status a. Current and Legal Protected Status i.

  • Freshwater Mussels of the National Park Service Obed Wild and Scenic River, Tennessee
    Malacological Review, 2017, 45/46: 193-211 FRESHWATER MUSSELS OF THE NATIONAL PARK SERVICE OBED WILD AND SCENIC RIVER, TENNESSEE Steven A. Ahlstedt1, Joseph F. Connell2, Steve Bakaletz3, and Mark T. Fagg4 ABSTRACT The Obed River was designated as a Wild and Scenic River (WSR) in 1976 and is a unit of the National Park Service. The river is considered to be among the highest quality in the state of Tennessee supporting a rich ecological diversity. Two federally listed species (one fish and one mussel) occur in the Obed: spotfin chub Cyprinella monacha, and purple bean Villosa perpurpurea. The Obed is a major tributary to the upper Emory River. Historical mussel collections and recent sampling have documented 27 species in the drainage. Freshwater mussel sampling was relegated to the Obed WSR and tributaries to determine species composition, abundance, and whether reproduction and recruitment is occurring to the fauna. Mussel sampling was conducted from 2000-2001 within the boundaries of the WSR at access points throughout the length of the Obed including portions of the upper Emory River, Daddy’s, Clear, and Whites creek. A total of 585 mussels representing nine species were found during the study. The most abundant mussel found was Villosa iris that comprised 55% of the fauna, followed by Lampsilis fasciola 19% and Medionidus conradicus 14%. The federally endangered V. perpurpurea was represented at 3%. Two species, Pleuronaia barnesiana (live) and Lampsilis cardium (fresh dead), were found as single individuals and P. barnesiana is a new distribution record for the Obed. The mussel fauna in the Obed WSR is relatively rare and historically the river may never have had a more diverse fauna because of the biologically non-productive nature of shale and sandstone that characterize streams on the Cumberland Plateau.
