The Global Decline of Nonmarine Mollusks
An overview of global nonmarine molluscan biodiversity and conservation status is provided, including several case studies documenting the diversity and global decline of nonmarinemollusks.
Phylogeny of North American amblemines (Bivalvia, Unionoida): prodigious polyphyly proves pervasive across genera
Parsimony and Bayesian analyses suggest that most amblemine genera, as currently defined, are polyphyletic, and the extent of Amblemini and the relationships of some genera previously assigned to that tribe remain unclear.
Molecular Systematics of Map Turtles (Graptemys): A Comparison of Mitochondrial Restriction Site Versus Sequence Data
?Analyses of mitochondrial DNA (mtDNA) restriction sites and sequences were used to estimate phylogenetic relationships in the emydid turtle genus Graptemys. We compared resolution and concordance…
Complete mtDNA sequence of the North American freshwater mussel, Lampsilis ornata (Unionidae): an examination of the evolution and phylogenetic utility of mitochondrial genome organization in…
The first complete nucleotide sequence of the mitochondrial (mt) genome of a North American freshwater bivalve, Lampsilis ornata, is reported and what role, if any, doubly uniparental inheritance and recombination between sexual mitotypes may play in influencing gene rearrangement of the mt genome in some bivalves lineages is discussed.
A Diverse and Endangered Aquatic Ecosystem of the Southeast United States
We document the biodiversity and conservation status of an extraordinarily diverse and endangered ecosystem in the United States that has failed to attract the same attention as tropical…
Molecular systematics and evolution of reproductive traits of North American freshwater unionacean mussels (Mollusca: Bivalvia) as inferred from 16S rRNA gene sequences.

A mitochondrial DNA (mtDNA) based phylogeny for North American unionacean mussels is presented and a 'total evidence' phylogeny which incorporates both the mtDNA sequence data and available morphological data is presented.
Molecular systematics of the North American freshwater bivalve genus Quadrula (Unionidae: Ambleminae) based on mitochondrial ND1 sequences.
A Molecular Phylogeny of Physidae (Gastropoda: Basommatophora) Based on Mitochondrial DNA Sequences
The molecular phylogeny based on mitochondrial sequences supports the monophyly of the family Physidae and six major clades were uncovered in the analysis, corresponding to differences in penial morphology.
CHAPTER 17 – The Phylogenetic Utility of the Mitochondrial Cytochrome b Gene for Inferring Relationships among Actinopterygian Fishes

A comparative analysis of complete mitochondrial ribosomal large subunit sequences of a chiton, two bivalves, six gastropod, and a cephalopod revealed substantial length variation among the taxa, with stylommatophoran gastropods possessing the shortest lengths.
