“…Furthermore, in all phylogenies, Q. quadrula is paraphyletic, with Q. apiculata and Q. rumphiana falling inside the clade (Figures ). The level of divergence between these three nominal taxa is actually lower than the divergence between the distinct clades of COI within Q. quadrula sensu stricto identified by Mathias, Hoffman, Wilson, and Zanatta () and also retrieved here in the COI phylogeny and haplotype network (Figures and a). A specific rank for each of these divergent clades was rejected in that study due to the existence of gene‐flow among them as shown by their microsatellite dataset (Mathias et al, ).…”

Freshwater mussels (Bivalvia, Unionidae) have suffered strong declines over the last century. High morphological plasticity of Unionidae causes disturbances in their systematics and taxonomy, hampering conservation efforts. Species that have historically been placed under the North American genus Quadrula have suffered from numerous taxonomic and species delineation problems since its inception. Four genera are presently recognized within Quadrula sensu lato, that is, Cyclonaias, Quadrula, Theliderma and Tritogonia, but their phylogenetic basis remains incompletely tested. In the present study, we reconstructed several two-marker (mtDNA cytochrome c oxidase subunit I-COI and NADH dehydrogenase subunit 1-ND1) phylogenies with newly collected specimens and all previously available sequences covering most species within this group. We then delineated the species within the group using an integrative approach with the application of molecular statistical methods, morphometric (Fourier Shape) analyses and geographic distribution data.Four clades corresponding to these genera were consistently recovered in all phylogenies. To validate the generic status of these clades, molecular analyses were complemented with morphological, anatomical and ecological data compiled from the literature. Several revisions are here proposed to the current systematics and taxonomy of these genera, including the synonymization of Cyclonaias asperata under Cyclonaias kieneriana; the inclusion of Quadrula apiculata and Quadrula rumphiana under Quadrula quadrula; the placement of Quadrula nobilis under Tritogonia; and finally the separation of the Mobile River basin populations of Theliderma metanevra as a new species, that is, Theliderma johnsoni n. sp. The conservation implications of the proposed changes are then discussed. 314 | LOPES-LIMA Et AL.

“…Propagation as a conservation tool was the subject of three studies: one about an improved method of in vitro culture of glochidia (Ma et al, 2016), one introducing short-term breeding of the Endangered freshwater pearl mussel Margaritifera margaritifera (Linnaeus, 1758) as a new technique for the augmentation of declining populations (Moorkens, 2017) and one revising the challenges in the conservation progress of Margaritifera auricularia (Spengler, 1793) . Six papers used molecular tools to describe genetic structure or phylogeographic patterns of European (Feind et al, 2017), North American (Hewitt et al, 2016;Mathias et al, 2016) and South American species (da Cruz Santos-Neto et al, 2017); to reveal the uncommon doubly uniparental inheritance of mitochondria in a European species (Soroka and Burzynski, 2017) and the sequencing of transcriptomic resources for an invasive species . The interaction between mussels and their host fishes was addressed in three papers that evaluate the effects of stress (Douda et al, 2016), cross-immunity (Chowdhury et al, 2017) and temperature (Schneider et al, 2017) on the reproduction of freshwater mussels.…”

Conservation of freshwater bivalves at the global scale: diversity, threats and research needs

et al. 2018

Bivalves are ubiquitous members of freshwater ecosystems and responsible for important functions and services. The present paper revises freshwater bivalve diversity, conservation status and threats at the global scale and discusses future research needs and management actions. The diversity patterns are uneven across the globe with hotspots in the interior basin in the United States of America (USA), Central America, Indian subcontinent and Southeast Asia. Freshwater bivalves are affected by multiple threats that vary across the globe; however, pollution and natural system (habitat) modifications being consistently found as the most impacting. Freshwater bivalves are among the most threatened groups in the world with 40% of the species being near threatened, threatened or extinct, and among them the order Unionida is the most endangered. We suggest that global cooperation between scientists, managers, politicians and general public, and application of new technologies (new generation sequencing and remote sensing, among others) will strengthen the quality of studies on the natural history and conservation of freshwater bivalves. Finally, we introduce

“…The population genetics of many aquatic and terrestrial plant and animal species occupying post‐glacial landscapes exhibit well‐documented spatial gradients in which concentrations of high genetic diversity in refugial (unglaciated) portions of species’ ranges gradually transition to areas of lower genetic diversity in more recently colonized, recently deglaciated portions of species’ ranges (Elderkin, Christhian, Vaughn, Metcalfe‐Smith, & Berg, 2007; Garner et al, 2004; Hewitt, 2000; Hewitt, Bergner, Woolnough, & Zanatta, 2018; Hoban et al, 2010; Mathias, Hoffman, Wilson, & Zanatta, 2018). Biogeographical patterns among most native aquatic species occupying the Great Lakes indicate that, after glaciers retreated in the Late Pleistocene, the lakes were colonized in a generally upstream‐to‐downstream or west‐to‐east direction from the upper Mississippi River basin (Bailey & Smith, 1981; Hewitt et al, 2018; Mandrak & Crossman, 1992; Mathias et al, 2018). Although hydrologic connections among lakes varied through time, the Niagara River is hypothesized to have been the principal dispersal corridor between lakes Erie and Ontario since early in their deglaciated history (Calkin & Feenstra, 1985), thus we predicted that an influence of these historical demographic processes might be detected in fish populations upstream from Niagara Falls having higher genetic diversity.…”

Is Niagara Falls a barrier to gene flow in riverine fishes? A test using genome‐wide SNP data from seven native species

et al. 2020

Since the early Holocene, fish population genetics in the Laurentian Great Lakes have been shaped by the dual influences of habitat structure and post‐glacial dispersal. Riverscape genetics theory predicts that longitudinal habitat corridors and unidirectional downstream water‐flow drive the downstream accumulation of genetic diversity, whereas post‐glacial dispersal theory predicts that fish genetic diversity should decrease with increasing distance from glacial refugia. This study examines populations of seven native fish species codistributed above and below the 58 m high Niagara Falls – a hypothesized barrier to gene flow in aquatic species. A better understanding of Niagara Falls’ role as a barrier to gene flow and dispersal is needed to identify drivers of Great Lakes genetic diversity and guide strategies to limit exotic species invasions. We used genome‐wide SNPs and coalescent models to test whether populations are: (a) genetically distinct, consistent with the Niagara Falls barrier hypothesis; (b) more genetically diverse upstream, consistent with post‐glacial expansion theory, or downstream, consistent with the riverscape habitat theory; and (c) have migrated either upstream or downstream past Niagara Falls. We found that genetic diversity is consistently greater below Niagara Falls and the falls are an effective barrier to migration, but two species have probably dispersed upstream past the falls after glacial retreat yet before opening of the Welland Canal. Models restricting migration to after opening of the Welland Canal were generally rejected. These results help explain how river habitat features affect aquatic species’ genetic diversity and highlight the need to better understand post‐glacial dispersal pathways.
