Freshwater mussels (Unionidae) are among the most imperiled groups of organisms in the world. Unionids are plagued with a lack of basic information regarding species distributions, life history characteristics, and ecological and biological requirements. We assessed the influence of hydrologic factors on the occurrence of the Suwannee Moccasinshell, Medionidus walkeri, a federally threatened freshwater mussel species endemic to the Suwannee River basin in Georgia and Florida. We also assessed the influence of survey effort on detection of M. walkeri during field surveys. All current (2013-2016) mussel survey records in the Suwannee River Basin were compiled, and cumulative discharge contributed by upstream springs...

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)].
This dataset contains raw sequence data collected from an eDNA metabarcoding project to detect freshwater mussel species across two sites in Georgia (Spring Creek and Flint River) and one drainage in Missouri (Big Piney River). The eDNA samples were collected from each stream using dead-end ultra filtration (D-HFUF) with eDNA extracted from filters. We used two previously published primer sets designed to amplify freshwater mussels, one that amplified the mitochondrial cytochrome c oxidase I (COI) region and one that amplified the NADH dehydrogenase subunit I region, with negative control and mock community samples included. Samples were individually indexed, pooled, and sequenced on an Illumina MiSeq high-throughput...
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...

Aim: North America harbours the most diverse freshwater mussel fauna on Earth. This fauna has high endemism at the continental scale and within individual river systems. Previous faunal classifications for North America were based on intuitive, subjective assessments of species distributions, primarily the occurrence of endemic species, and do not portray continent-wide patterns of faunal similarity. The aim of this study is to provide an analytical portrayal of patterns of mussel diversity in a hierarchical framework that informs the biogeographical history of the fauna. Published in Journal of Biogeography, volume 37, issue 1, on pages 12 - 26, in 2010.
