“…Understanding the evolution and ecology of the Ambleminae and its tribes is an important focus of freshwater biodiversity research in North America and has positively influenced many aspects of applied freshwater science (e.g., Serb et al, 2003;Zanatta & Murphy, 2006;Barnhart et al, 2008;Haag & Rypel, 2011;Campbell & Lydeard, 2012;Haag, 2012); however, the current theory of amblemine phylogeny, biogeography, and ecology is strongly geographically biased due to the near complete exclusion of Mesoamerican taxa from recent research. Comprehensive understanding of the Ambleminae, its tribes, and several of its genera, necessitates inclusion of Mesoamerican representatives, and their consideration is likely to have major implications in various disciplines of freshwater mussel research (e.g., evolutionary biology, ecology, and conservation).…”

Megalonaias is the most geographically widespread genus of the subfamily Ambleminae and is distributed across much of the eastern half of North America, from Minnesota to Nicaragua. Despite the large geographic distribution, the species-level diversity of Megalonaias is quite depauperate (2 spp.), suggesting the genus may not be constrained by the same physical, ecological, or physiological barriers that limit dispersal in many other amblemines. However, this hypothesis is contingent on the assumption that the current taxonomy of Megalonaias accurately reflects its evolutionary history, which remains incompletely understood due to the marginalization of Mesoamerican populations in systematic research. Using one mitochondrial (COI) and one nuclear marker (ITS1) sequenced from 41 individuals distributed across both the Nearctic and Mesoamerican ecoregions, we set out to better understand the species boundaries and genetic diversity within Megalonaias. The reconstructed molecular phylogeny and the observed genetic diversity suggests that Megalonaias is a monotypic genus and that Megalonaias nickliniana, currently considered a federally endangered species, is not a valid species. These results are discussed in the context of their systematic and conservation implications, as well as how the unusual life history strategy of Megalonaias may be influencing its molecular diversity.

“…Although the phylogenetic clades correspond to drainage, this pattern was replicated within C. aberti, where two genetically distinct sympatric lineages were identified within the Ouachita River system as non-sister clades (Serb, 2006). If the mitochondrial gene tree accurately describes the species tree, these data suggest that there are as many as five distinct evolutionary lineages within C. aberti (Serb, 2006). To test the accuracy of this biodiversity assessment, we compared molecular, geographic, and reproductive characters.…”

Organisms with complex life histories and unusual modes of genome inheritance can present challenges for phylogenetic reconstruction and accurate assessment of biological diversity. This is particularly true for freshwater bivalves in the family Unionidae because: (1) they have complex life cycles that include a parasitic larva and obligate fish host; (2) they possess both a male and female mitochondrial genome that is transmitted through doubly uniparental inheritance (DUI); and (3) they are found in riverine habitats with complex hydrogeological histories. Examination of mitochondrial DNA (mtDNA) sequences, conglutinate morphology, and host fish compatibility of the western fanshell Cyprogenia aberti (Conrad, 1850) revealed significant character variation across its range. Although variation was correlated among the different data sets and supports discrete groups, these groups did not always correspond to geographically isolated populations. Two discrete mtDNA clades exist sympatrically within most C. aberti populations, and these same clades are also diagnosed by at least one morphological character, egg color. The surprisingly high genetic distance (14. 61%-20.19%) between the members of these sympatric clades suggests heritance infidelity of the two different mitochondrial genomes. This hypothesis was tested and falsified. More general patterns in geography were observed in host fish compatibility. Populations of C. aberti from the major river systems differed in their ability to utilize fish species as hosts. These differences in reproductive traits, which are presumably genetically based, suggest that these populations are not ecologically exchangeable with one another and represent biological diversity not previously recognized within Cyprogenia Agassiz, 1852.

ABSTRACT1. The duck mussel, Anodonta anatina, has been described as abundant and widespread in Europe. However, it is listed as near threatened or threatened in several countries owing to severe declines in abundance and/or spatial distribution.2. Despite its potential ecological importance and conservation status almost nothing is known regarding its genetic diversity.3. As a preliminary analysis, variation within the cytochrome oxidase 1 mitochondrial gene was determined from European specimens from Portugal in the south west, to Ukraine in the east, and Sweden in the north.4. Three major mtDNA clades were retrieved: clade 1 includes all the individuals from Iberia, except those from the Ebro basin; clade 2 includes all the European non-Iberian and non-Italian samples; and clade 3 includes all the individuals from Italy and from the Ebro basin. AMOVA analysis revealed significant genetic differences among the three clades. Within each of the major clades, several geographically related haplogroups were also retrieved, especially in Iberia, where four genetically distinct groups (North-West, South-Central, South-West and Ebro) were revealed.5. Given the evidence of regional declines of A. anatina in Europe, the confirmation of geographically distinct genotypes indicates a need for the development of management strategies directed towards the conservation of localized populations.
