    Sensitivity of freshwater snails to aquatic contaminants: Survival and growth of endangered snail species and surrogates in 28-day exposures to copper, ammonia and pentachlorophenol John M. Besser, Douglas L. Hardesty, I. Eugene Greer, and Christopher G. Ingersoll U.S. Geological Survey, Columbia Environmental Research Center, Columbia, Missouri Administrative Report (CERC-8335-FY07-20-10) submitted to U.S. Environmental Protection Agency (USEPA) Project Number: 05-TOX-04, Basis 8335C2F, Task 3. Project Officer: Dr. David R. Mount USEPA/ORD/NHEERL Mid-Continent Ecology Division 6201 Congdon Blvd, Duluth, MN 55804 USA April 13, 2009 Abstract – Water quality degradation may be an important factor affecting declining populations of freshwater snails, many of which are listed as endangered or threatened under the U.S. Endangered Species Act. Toxicity data for snails used to develop U.S. national recommended water quality criteria include mainly results of acute tests with pulmonate (air-breathing) snails, rather than the non-pulmonate snail taxa that are more frequently endangered. Pulmonate pond snails (Lymnaea stagnalis) were obtained from established laboratory cultures and four taxa of non-pulmonate taxa from field collections. Field-collected snails included two endangered species from the Snake River valley of Idaho -- Idaho springsnail (Pyrgulopsis idahoensis; which has since been de-listed) and Bliss Rapids snail (Taylorconcha serpenticola) -- and two non-listed taxa, a pebblesnail (Fluminicola sp.) collected from the Snake River and Ozark springsnail (Fontigens aldrichi) from southern Missouri. Cultures were maintained using simple static-renewal systems, with adults removed periodically from aquaria to allow isolation of neonates for long-term toxicity testing.

  • Native Unionoida Surveys, Distribution, and Metapopulation Dynamics in the Jordan River-Utah Lake Drainage, UT
    Version 1.5 Native Unionoida Surveys, Distribution, and Metapopulation Dynamics in the Jordan River-Utah Lake Drainage, UT Report To: Wasatch Front Water Quality Council Salt Lake City, UT By: David C. Richards, Ph.D. OreoHelix Consulting Vineyard, UT 84058 email: [email protected] phone: 406.580.7816 May 26, 2017 Native Unionoida Surveys and Metapopulation Dynamics Jordan River-Utah Lake Drainage 1 One of the few remaining live adult Anodonta found lying on the surface of what was mostly comprised of thousands of invasive Asian clams, Corbicula, in Currant Creek, a former tributary to Utah Lake, August 2016. Summary North America supports the richest diversity of freshwater mollusks on the planet. Although the western USA is relatively mollusk depauperate, the one exception is the historically rich molluskan fauna of the Bonneville Basin area, including waters that enter terminal Great Salt Lake and in particular those waters in the Jordan River-Utah Lake drainage. These mollusk taxa serve vital ecosystem functions and are truly a Utah natural heritage. Unfortunately, freshwater mollusks are also the most imperiled animal groups in the world, including those found in UT. The distribution, status, and ecologies of Utah’s freshwater mussels are poorly known, despite this unique and irreplaceable natural heritage and their protection under the Clean Water Act. Very few mussel specific surveys have been conducted in UT which requires specialized training, survey methods, and identification. We conducted the most extensive and intensive survey of native mussels in the Jordan River-Utah Lake drainage to date from 2014 to 2016 using a combination of reconnaissance and qualitative mussel survey methods.

This direction would standardize invasive plant prevention, and expand the set of invasive plant treatment tools available for use on National Forests in Region Six. The FEIS considers four alternatives in detail (including No Action). Adoption of the standards in any of the action alternatives would likely reduce the extent and rate of spread of invasive plants across the region, and help prevent new infestations. All of the action alternatives include standards to protect human health and the environment. The Forest Service preferred alternative is the Proposed Action.

  • (Pyrgulopsis Robusta), Harney Lake Springsnail (Pyrgulopsis Hendersoni), and Columbia Springsnail (Pyrgulopsis New Species 6) As Threatened Or Endangered
    PETITION BEFORE THE SECRETARY OF THE INTERIOR Petition to List the Jackson Lake springsnail (Pyrgulopsis robusta), Harney Lake springsnail (Pyrgulopsis hendersoni), and Columbia springsnail (Pyrgulopsis new species 6) as Threatened or Endangered Submitted by: Dr. Peter Bowler, Biodiversity Conservation Alliance, Center for Biological Diversity, Center for Native Ecosystems, Western Watersheds Project, The Xerces Society July 2004 EXECUTIVE SUMMARY Invertebrates comprise nearly 99% of the world’s animal diversity and play an invaluable role in maintaining environmental health and integrity. Invertebrates are a part of nearly every food chain, are responsible for recycling plant and animal waste in soils and waters, and are crucial to ensuring the perpetuation of food webs. Mollusks, invertebrates characterized by their shells and which include snails, slugs, clams, mussels, and other creatures, are one of the most diverse group of animals in the world. Worldwide, it is estimated that 50,000-200,000 different mollusk species exist on land and in freshwater. These species exist in an incredible diversity of environments, playing a vital role in sustaining clean and healthy air, soil, water, and vegetation. In the western United States, which includes the states of Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming, land and freshwater mollusks are probably the most diverse group of animals and comprise an irreplaceable proportion of worldwide diversity. Over a thousand species of snails, slugs, clams, and mussels are found on land and in freshwater. Scientists estimate hundreds more species have yet to be discovered. Some species in the west exist in only one or two locations, such as a desert spring, a stand of ancient forest, or a coastal island, and are found nowhere else in the world.

  • Bliss Rapids Snail Taylorconcha Serpenticola
    Bliss Rapids Snail Taylorconcha serpenticola Gastropoda — Neotaenioglossa — Hydrobiidae CONSERVATION STATUS / CLASSIFICATION Rangewide: Critically imperiled (G1) Statewide: Critically imperiled (S1) ESA: Threatened USFS: Region 1: No status; Region 4: No status BLM: Threatened, Endangered, Proposed, and Candidate (Type 1) IDFG: Not classified BASIS FOR INCLUSION Threatened under the U.S. Endangered Species Act. TAXONOMY Taylorconcha, as currently arranged, is a monotypic genus. Richards et al. (2005) encountered populations of Taylorconcha in Hell’s Canyon that are thought to represent an undescribed taxon rather than new populations of the Bliss Rapids snail. DISTRIBUTION AND ABUNDANCE This aquatic snail is endemic to the Snake River and associated springs. Historically, this species occurred from Indian Cove Bridge to Twin Falls (Hershler et al. 1994). Populations occur in the lower reaches of the Malad River and in the Snake River between the springs above Hagerman and King Hill (W. Clarke, Idaho Power Company, personal communication). Recent surveys in Hells Canyon have revealed populations of snails referable to this genus, but these records may represent a taxon distinct from T. serpenticola. If these populations are thought to represent the Bliss Rapids snail, the distribution would extend into the lower reaches of the Snake River. POPULATION TREND No data are available to suggest population trend. HABITAT AND ECOLOGY The Bliss Rapids snail inhabits springs and spring-influenced river reaches. Occupied sites are in flowing water having coarse, stable substrates and excellent water quality. Water temperatures generally range from 15 to 16°C. This species is typically absent from areas with impoundments and major depth fluctuations, warm-water environments, whitewater, and sites predominant aquatic macrophytes (Hershler et al.

Although the western USA is relatively mollusk depauperate, the one exception is the rich molluskan fauna of the Bonneville Basin area, including drainages that enter terminal Great Salt Lake (e.g. Utah Lake, Jordan River, Bear River, etc.). There are at least seventy freshwater mollusk taxa reported from UT, many of which are endemics to the Bonneville Basin and their evolution and distribution are strongly linked with the geological and geomorphic history of pluvial Lake Bonneville. These mollusk taxa serve vital ecosystem functions and are truly a Utah natural heritage. Unfortunately, freshwater mollusks are also the most imperiled animal groups in the world; including those found in UT. Despite this unique and irreplaceable natural heritage, the taxonomy, distribution, status, and ecologies of Utah’s freshwater mollusks are poorly known. Very few mollusk specific surveys have been conducted in UT. In addition, specialized training, survey methods, and identification of freshwater mollusks are required. EPA recently recommended changes in freshwater ammonia criteria based primarily on sensitive freshwater mollusks, including non-pulmonate snails and unionid taxa found in the eastern USA.

  • Two Additional Western United States Freshwater Snails Named for Terrence Frest by Edward J
    Two additional western United States freshwater snails named for Terrence Frest by Edward J. Johannes As was noted in a previous issue of The Dredgings (Holm, 2009), Terrence (Terry) J. Frest was posthumously honored by having a snail he collected from the Owyhee River drainage in Oregon named for him (Pyrgulopsis fresti Hershler and Liu, 2009; Owyhee hot springsnail). This snail was discovered by Bureau of Land Management (BLM) personnel during a helicopter survey to search for additional sites for the federally listed (endangered) Pyrgulopsis bruneauensis (Bruneau hot springsnail). Just recently two western U.S. freshwater snails, one a limpet, have been named for Terry. The limpet, in addition to being a new species, is also a new genus and was named Idaholanx fresti Campbell, Clark, and Lydeard, 2017 (Banbury Springs lanx; also known as the Banbury Springs limpet) (Figure 1). This species is in the subfamily Lancinae, within Lymnaeidae, that contain two other patelliform genera, Lanx and Fisherola (Figure 2). Lanx currently occurs in northern California and southern Oregon with the species L. patelloides (kneecap lanx) in the Sacramento and Klamath rivers and L. alta (highcap lanx) in the Smith, Umpqua and Rogue rivers. L. subrotunda and L. klamathensis are synonymized with L. alta by Campbell et al. (2017). Campbell et al. (2017) only recognized Fisherola nuttallii (shortface lanx) in this genus. It’s found confined to Figure 1 - Holotype of Idaholanx fresti the Columbia River system in From Campbell et al., 2017. Washington, Oregon, Montana, Idaho and a small portion of British Columbia, Canada. Idaholanx, has the most restricted occurrence, being found only in four nearby large springs in the Thousand Springs area of the Snake River, Gooding County, Idaho (Figure 3).
