Journal ArticleDOI
Review of the systematics and global diversity of freshwater mussel species (bivalvia: unionoida)
Daniel L. Graf,Kevin S. Cummings +1 more
TL;DR: The species-level diversity of the Unionoida is described by reviewing the secondary literature and developing a comprehensive taxonomic database, and it is suggested that reevaluation of these faunas with modern methods will likely increase recognized species diversity, especially on the southern continents.
Journal ArticleDOI
Investigating the Bivalve Tree of Life -- an exemplar-based approach combining molecular and novel morphological characters.
Rüdiger Bieler,Paula M. Mikkelsen,Timothy M. Collins,Emily A. Glover,Vanessa L. González,Daniel L. Graf,Elizabeth M. Harper,John M. Healy,John M. Healy,Gisele Y. Kawauchi,Prashant P. Sharma,Sid Staubach,Ellen E. Strong,John D. Taylor,Ilya Tëmkin,Ilya Tëmkin,John D. Zardus,Stephanie Clark,Alejandra Guzmán,Alejandra Guzmán,Erin McIntyre,Paul Sharp,Gonzalo Giribet +22 more
TL;DR: An analysis of the informativeness of morphological characters showed that sperm ultrastructure characters are among the best morphological features to diagnose bivalve clades, followed by characters of the shell, including its microstructure.
Journal ArticleDOI
Palaeoheterodont diversity (Mollusca: Trigonioida + Unionoida): what we know and what we wish we knew about freshwater mussel evolution
Daniel L. Graf,Kevin S. Cummings +1 more
TL;DR: From the ‘combined evidence’ topology (with problematic sequences excluded), the Unionoida is monophyletic on the basis of eight synapomorphies, including larval parasitism, brood protection, and restriction to freshwater.
Journal ArticleDOI
The evolution of brooding characters among the freshwater pearly mussels (bivalvia: unionoidea) of north america
TL;DR: This study evaluated phylogenetic hypotheses of brooding character evolution in order to test homology statements suggested by earlier taxonomic systems of the Unionoidea, and indicated that long-term brooding (bradytictia) is the derived state among North American freshwater mussels.
Journal ArticleDOI
A family-level Tree of Life for bivalves based on a Sanger-sequencing approach
David J. Combosch,Timothy M. Collins,Emily A. Glover,Daniel L. Graf,Elizabeth M. Harper,John M. Healy,Gisele Y. Kawauchi,Sarah Lemer,Erin McIntyre,Ellen E. Strong,John D. Taylor,John D. Zardus,Paula M. Mikkelsen,Gonzalo Giribet,Gonzalo Giribet,Gonzalo Giribet,Rüdiger Bieler +16 more
TL;DR: The systematics of the molluscan class Bivalvia are explored using a 5-gene Sanger-based approach including the largest taxon sampling to date, encompassing 219 ingroup species spanning 93 (or 82%) of the 113 currently accepted bivalve families, finding that many families are not supported, and several are supported as non-monophyletic.
