Novel genetic resources to facilitate future molecular studies in freshwater mussels (Bivalvia: Unionidae)
Here we provide public access to six DNA sequence alignments and details on all specimens utilized in Smith and Johnson (2020).
The diagnosis of bacterial disease in freshwater unionid mussels has been hindered by a lack of baseline information regarding the microbial communities associated with these animals. In this study, we cultured and identified bacteria from the hemolymph of stable mussel populations from the upper Mississippi River basin and compared results to mussel populations associated with a mortality event in the Clinch River, VA and TN. Several bacterial genera were consistently identified across mussel species and locations, appearing to be part of the natural bacterial flora. One noteworthy isolate was identified from the Clinch River. Yokenella regensbergei was found with relatively high prevalence during the mortality...
Molecular and morphological data to resolve species boundaries in the critically imperiled freshwater mussel species, Fusconaia mitchelli
We generated multilocus DNA sequence data and traditional morphometric measurements to evaluate species boundaries in Fusconaia mitchelli. We sequenced three loci: the protein-coding mitochondrial DNA genes cytochrome oxidase subunit 1 and NADH dehydrogenase 1, and the nuclear ribosomal internal transcribed spacer 1. We also took three measurements, maximum length, maximum width, and maximum height, of mussel shells for morphometric analysis.
Molecular data to investigate phylogeographic patterns, species boundaries, and demographic history of a North American freshwater mussel species complex (Bivalvia: Unionidae)
Here we provide public access to three DNA sequence alignments (COI, ND1, ITS1) and details on all specimens utilized in Keogh et al. (in review).
The Southeastern and Mid-Atlantic regions of the United States contain the greatest biodiversity of native freshwater mussels in the world, but they are highly imperiled due to habitat alteration and destruction, pollution and poor water quality, and the introduction of aquatic invasive species. Now they are at even greater risk from the stresses associated with climate change-induced sea level rise and its associated changes in salinity, water temperature, and stream flow. This project investigates the potential vulnerability and adaptation of a native freshwater mussel, the Tidewater Mucket, in coastal river systems and offer solutions for its conservation. Scientists have recently discovered a population of...
Host fishes for the endangered dwarf wedgemussel (Alasmidonta heterodon) from various locations in the northeastern United States (1999-2007)
Data is included for three sets of laboratory experiments where various fish species were tested in several multi-week trials to determine their suitability in serving as parasitic hosts for larvae of the freshwater mussel named dwarf wedgemussel (Alasmidonta heterodon) from the Mid-Atlantic region and New England of the United States. The first set of experiments tested host suitability of multiple fish species, the second compared host suitability of groups of tessellated darters (Etheostoma olmstedi; a known host) from multiple locations, and the third tested host suitability of individual tessellated darters. Results are reported in numbers of juvenile mussels per fish (JPF; total juvenile mussels produced by...
Chronic (28-d) toxicity of 4-nonylphenol (4-NP) to two commonly tested species of mussels: fatmucket (Lampsilis siliquoidea) and rainbow mussel (Villosa iris).
Data include burrowing behavior of juvenile freshwater mussels (Lampsilis siliquoidea); Villosa constricta; Megalonaias nervosa; Villosa iris; Lampsilis powellii; and Anodonta oregonensis) in three types of sediment [a sand/silt/clay mixture (49% sand) with a total organic carbon (TOC) content of about 3% obtained from northeastern Minnesota, a predominantly fine sand (82% sand) with a TOC content of about 1% obtained from southwest Missouri, and a coarse commercial sand with a diameter of < 0.5 mm (Granusil, #4030)].
The effects of 28-day exposure to elevated carbon dioxide on survival, growth and condition of juvenile life stage of Lampsilis siliquoidea and Lampsilis higginsii mussels: Data
The use of carbon dioxide to control aquatic invasive species (AIS) prompted an evaluation of its effects on native freshwater mussels that may reside in areas of infusion. We exposed juvenile mussels (~6-mo old) of two species, the fat mucket (Lampsilis siliquoidea) and the federally endangered Higgins’ Eye (L. higginsii) to CO2 concentrations proposed for AIS control (24,000 – 96,000 µatm pCO2 ) for 28 d followed by a 14-d recovery period and compared their survival, growth, and behavior. Additionally, tissue and shell condition and transcriptomic response of four genes were measured in L. siliquoidea. Survival was similar between species; the 14-d postexposure LC50 for L.higginsii was 61,000 µatm pCO2 (95% CL...
Qualitative and quantitative surveys of native freshwater mussels in the upper and middle Delaware River (2000-2002)
Data is included for two types of field surveys conducted for freshwater mussels in the mainstem of the middle and upper Delaware River in the Mid-Atlantic region of the United States from 2000-2002. Timed search (qualitative) surveys were conducted during 2000-2001 from a point at the confluence of the East and West Branches of the Delaware River near Hancock, NY continuously downstream to a point at the mouth of the Paulins Kill River near Columbia, NJ. In this qualitative survey, mussel species and counts were collected in the field catch-per-unit-effort (CPUE) data was determined for all mussel species within each of 1,095 consecutive stream sections ~200 m in length. Subsequent quantitative surveys were conducted...
This dataset includes information from multiple taxa collected from four main reaches in the Upper Mississippi River Basin, including La Grange reach of Illinois River, Pool 2 of Mississippi River, Pool 19 of Mississippi River, and the St. Croix River. Taxa include hydropsychid caddisflies, chironomids, hexagenia mayflies, threeridge mussels, mapleleaf mussels, Wabash pigtoe mussels, bigmouth buffalo, gizzard shad, and bluegill. Seston samples were also collected, in addition to water samples for identifying and enumerating phytoplankton species. Fatty acids, lipids, and stable isotopes were quantified for the aforementioned taxa. Water quality data were recorded at the time of sample collection and discharge data...
