  • FMCS Comment Letter in Support of PA Mussel Listing
    December 29, 2008 Dr. Douglas J. Austen Executive Director Pennsylvania Fish and Boat Commission P.O. Box 67000 Harrisburg, PA 17106-7000 Dear Dr. Austen, The Freshwater Mollusk Conservation Society (FMCS) is writing to express our support of the Pennsylvania Fish and Boat Commission’s proposed rule to list five mussels (Epioblasma triquetra, Plethobasus cyphyus, Quadrula c. cylindrica, Simpsonaias ambigua, and Villosa fabalis) as Endangered or Threatened in the Commonwealth of Pennsylvania. The FMCS is a non-profit entity whose mission includes education, research, and protection of freshwater mollusks, North America’s most imperiled group of animals. Our membership includes individuals affiliated with state and federal government, academia, as well as amateur collectors and citizen scientists. As you are aware, all of the species proposed for listing have been ranked by the bivalve technical committee of the Pennsylvania Biological Survey as Critically Imperiled (S1) or Critically Imperiled/Threatened (S1/S2). Additionally, these species are ranked globally as either Imperiled (G2) or Vulnerable (G3) (NatureServe 2008). The species proposed for listing meet the criteria that have been developed by the commission for listing threatened and endangered mussels, which are based on the IUCN Red List criteria. Freshwater mussels are considered one of the most imperiled fauna in North America, with approximately 213 of the 297 recognized taxa considered endangered, threatened or of special concern (Lydeard et al. 2004, NatureServe 2008, Ricciardi and Rasmussen 1999, Williams et al. 1993). Of the approximately 65 species of freshwater mussels that have been known historically from Pennsylvania, 13 (20%) are considered historic or possibly extirpated.

We recognize a total of 298 species in 55 genera in the families Margaritiferidae (one genus, five species) and Unionidae (54 genera, 293 species). We propose one change in the Margaritiferidae: the placement of the formerly monotypic genus Cumberlandia in the synonymy of Margaritifera. In the Unionidae, we recognize three new genera, elevate four genera from synonymy, and place three previously recognized genera in synonymy.

  • Iowa Fish and Wildlife and Species of Greatest Conservation Need
    Chapter Three Iowa Fish and Wildlife and Species of Greatest Conservation Need Required Element #1: “Information on the distribution and abundance of species of wildlife, including low and declining populations as the state fish and wildlife agency deems appropriate, that are indicative of the diversity and health of the state’s wildlife.” Species Included in the Iowa Wildlife Action Plan The DNR is the sole agency given the responsibility to manage Iowa's fish and wildlife resources, preserve their habitats (Code of Iowa, Chapter 455A), and establish and protect state-listed endangered or threatened species (chapter 481B.4 and Iowa Administrative Code Chapter 571-77(481B)). Iowa law defines wildlife as any species of wild mammal, fish, bird, reptile or amphibian (Code of Iowa sections 456.24, 481A.1, 481A.38, 481A.39, 481A.48). In addition to taxonomic groups designated as wildlife in Iowa law, this Plan is intended to guide conservation of all Iowa’s native fauna for which an adequate level of information is available to assess the conservation status and needs. In the first version of the Plan, butterflies, land snails and fresh water mussels were included, because these invertebrates are listed on the state’s endangered and threatened species list. Dragonflies and damselflies were added when significant data were found that listed the distribution and status of species in these groups. For the 2015 version, consideration was given to adding crayfish. A total of 1,115 species were evaluated by subcommittees. Subcommittees considered all species which have been documented in Iowa, including some species which may be vagrant, expanding their range, have been introduced, or have already been extirpated (Table 3- 1).

ABSTRACT Conservation and restoration of freshwater mussel species requires an understanding of current and historical distributions as well as key aspects of life history. Most freshwater mussels (Unionoida) depend on particular species of host fish for the development and dispersal of the parasitic glochidia larvae.The degree of host specificity varies and is not well known for many mussel species. We tested 90 fish species in 18 families as potential hosts for the Monkeyface mussel (Theliderma metanevra), determined its brooding period, and assessed its distribution and current status in Minnesota and Wisconsin. Theliderma metanevra brood embryos and glochidia from late April-early August in the St.

    Status Assessment Report for the sheepnose, Plethobasus cyphyus, occurring in the Mississippi River system (U.S. Fish and Wildlife Service Regions 3, 4, and 5) Prepared by Ohio River Valley Ecosystem Team Mollusk Subgroup Robert S. Butler, Leader U.S. Fish and Wildlife Service 160 Zillicoa Street Asheville NC 28801 September 2002 1 Disclaimer This document is a compilation of biological data and a description of past, present, and likely future threats to the sheepnose (Plethobasus cyphyus). It does not represent a decision by the U.S. Fish and Wildlife Service (Service) on whether this taxon should be designated as a candidate species for listing as threatened or endangered under the Federal Endangered Species Act. That decision will be made by the Service after reviewing this document; other relevant biological and threat data not included herein; and all relevant laws, regulations, and policies. The result of the decision will be posted on the Service's Region 3 Web site (refer to: http://midwest.fws.gov/eco_serv/endangrd/lists/concern.html). If designated as a candidate species, the taxon will subsequently be added to the Service's candidate species list that is periodically published in the Federal Register and posted on the World Wide Web (refer to: http://endangered.fws.gov/wildlife.html). Even if the taxon does not warrant candidate status it should benefit from the conservation recommendations that are contained in this document. 2 Common name: sheepnose Scientific name: Plethobasus cyphyus Controversial or unsettled taxonomic issues: The sheepnose is a member of the mussel family Unionidae and was originally described as Obliquaria cyphya Rafinesque, 1820.
