Longstanding taxonomic uncertainties have limited conservation efforts for species currently assigned to the freshwater mussel genus Alasmidonta. Here, we present mitochondrial and nuclear DNA sequence data needed to assess the genus- and species-level taxonomy of Alasmidonta. These molecular data allowed us to test whether cryptic diversity exists within Alasmidonta and whether A. triangulata and A. arcula are distinct species. Details associated with specimens and DNA sequence data are provided here to provide a foundation for future research on Alasmidonta and give conservation agencies greater confidence in the findings of our work.

Here we provide the molecular datasets and metadata associated with specimens used in the investigation of species boundaries and phylogeographic structure of two freshwater mussels, one common (Pleurobema sintoxia) and one being considered for protection under the Endangered Species Act (Pleurobema rubrum).

The widespread distribution of Strophitus undulatus, as well as high intraspecific morphological variation, has led previous authors to doubt the taxon is representative of a single species. Here we provide detailed information for all the freshwater mussels and associated DNA sequence data utilized to test species boundaries in S. undulatus. These molecular data, in combination with morphological data and results from species distribution models, support the recognition of an undescribed freshwater mussel species endemic to streams along the Edwards Plateau in the Colorado River basin in Texas, USA.

This dataset contains environmental DNA (eDNA) concentrations and spawning adult abundances for sockeye salmon (Oncorhynchus nerka) in Hansen Creek, a small tributary in the Wood River watershed, southeast Alaska, USA. We took temporally- and spatially-replicated eDNA samples during the spawning period (mid-July through August), along with fish counts (live, naturally dead, and killed), dissolved oxygen (DO), discharge, and temperature data at each time of sampling. Samples were collected at each site before adults entered the stream, and then continued to be collected daily or every other day for the next three weeks.

The North American freshwater mussel tribe Quadrulini has a suite of life history adaptations, however, the evolution of life histories in this group has yet to be explored using comparative phylogenetic methods. Here we provide the AHE DNA sequence alignment representing 27 species from the subfamily Ambleminae that was used to estimate a phylogenomic reconstruction of Quadrulini. Additionally, we provide a compilation of host use information and larval length and height measurements utilized to trace the evolution of life history characteristics, such as larval morphology and host attraction strategy. Phylogenetic trees are presented representing phylogenetic inference performed under Maximum Likelihood, Maximum...

We examined species boundaries within an imperiled group of freshwater mussels in the genus Cyclonaias (Bivalvia: Unionidae) using morphometrics, molecular phylogenetics, and multispecies coalescent models to help guide pending conservation assessments and legislative decisions. Congruence across all lines of evidence indicated that current taxonomy overestimates diversity in the C. pustulosa species complex, while underestimating diversity in the C. nodulata species complex. Here we provide all molecular, morphological, and collection information collected and analyzed in our investigation.
