Pearly mussels in NY State Susquehanna Watershed Paul H. Lord, Willard N. Harman & Timothy N. Pokorny Introduction Preliminary Results Discussion Pearly mussels (unionids) New unionid SGCN identified • Mobile substrates appear exacerbated endangered native mollusks in Susquehanna River Watershed by surge stormwater inputs • Life cycle complex • Eastern Pearlshell (Margaritifera margaritifera) - made worse by impervious surfaces - includes fish parasitism -- in Otselic River headwaters • Unionids impacted - involves watershed quality parameters Historical SGCN found in many locations by ↓O2, siltation, endocrine disrupting chemicals • 4 Species of Greatest Conservation Need • Regularly downstream of extended riffle - from human watershed use (SGCN) historically found • Require minimally mobile substrates • River location consistency with old maps in NY State Susquehanna Watershed • No observed wastewater treatment plant impact associated with ↑ unionids - Brook Floater (Alasmidonta varicosa) -adult unionids more easily observed - Green Floater (Lasmigona subviridis) Table 1.

Atlas of the Freshwater Mussels (Unionidae)
1 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 by Robert A. 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. Additional information on these preserves and programs is available from the Estuarine Reserves Division, Office for Coastal Management, National Oceanic and Atmospheric Administration, U. S.

While the northeast holds the largest brook floater populations range wide, our long-term research shows populations once large and robust have either declined by 50 to 95% or are gone completely. We are apprehensive that most populations are facing the same fate, but trends are often undetected because of the lack of long-term monitoring. Although the brook floater was petitioned recently for listing under the Endangered Species Act, serious data gaps remain. -

These small streams of moderate to low elevations occur on flats or very gentle slopes in watersheds less than 39 sq.mi in size. The cool slow-moving waters may have high turbidity and be somewhat poorly oxygenated. Instream habitats are dominated by glide-pool and ripple-dune systems with runs interspersed by pools and a few short or no distinct riffles. Bed materials are predominenly sands, silt, and only isolated amounts of gravel.

The brook floater rarely exceeds three inches (75mm) in length. The shape is has a unique habit of “gaping” (relaxing its adductor trapezoidal to almost elliptical, and it has a prominent muscles and opening its valves) when removed from the posterior ridge that gives it a “roman nose” lateral profile water, exposing its cantaloupe-colored foot and mantle (1). The ventral margin (2) is usually flat or slightly cavity. indented. The valves are moderately inflated (3), giving it Similar Species in Massachusetts: Brook floater shells a swollen appearance in cross section. The periostracum (dead animals) can be identified without difficulty, (4) is yellowish-green in young animals to brownish-black although sometimes are confused with the creeper, which in mature specimens and usually has prominent green rays has a similar shape and poorly developed pseudocardinal (5). Rays are often obscure in heavily eroded or stained teeth. Accurate identification of live animals usually relies shells. The diagnostic feature for this species is a series of on the corrugations on the shell, shape of the animal, corrugations (or raised ridges) along the dorso-posterior cantaloupe-colored foot, and its habit of gaping when slope (6), perpendicular to the growth lines; these removed from the water. Live juveniles or highly eroded corrugations are difficult to discern on shells that are adult brook floater, triangle floater, and creeper can young, eroded, stained, or covered with algae. -
