Phylogenetic relationships and evolution of pulmonate gastropods (Mollusca): new insights from increased taxon sampling.
Phylogenetic relationships among higher clades of pulmonate gastropods are reconstructed based on a data set including one nuclear marker and two mitochondrial markers for a total of 96 species, with a special emphasis on sampling the Ellobiidae, Onchidiidae, and Veronicellidae. Expand
A molecular phylogeny of the bivalve mollusks.
A phylogenetic reconstruction based on 506 nucleotides near the 5' end of the 18S subunit of ribosomal DNA (rDNA) in 2 gastropod, 3 chiton and 28 bivalve mollusks could not confidently establish either the monophyly or the phylogenetic relationships of the morphologically well defined subclasses Pteriomorphia, Protobranchia, and Anomalodesmata.

Population divergence in the sinistral whelks of North America, with special reference to the east Florida ecotone
High levels of divergence between the allopatric western Atlantic and Gulf of Mexico populations, as revealed by fixed or nearly fixed differences at several allozyme-encoding loci were interpreted as evidence that the east Florida ecotone constitutes a significant barrier to gene flow. Expand
A molecular phylogeny of the Patellogastropoda (Mollusca: Gastropoda)
Partial 18S sequences support the inclusion of the family Neolepetopsidae within the superfamily Acmaeoidea, and refute its previously hypothesized position as sister group to the remaining living Patellogastropoda. Expand
Pleurotomarioidean gastropods.
The anatomical and molecular data are reviewed; the latter used to produce a well-resolved phylogeny of the genera within the family, and to justify the naming of the long-used informal grouping "Perotrochus Group B" as the genus BayerotroChus. Expand
Phylogenetic relationships of the lower Caenogastropoda (Mollusca, Gastropoda, Architaenioglossa, Campaniloidea, Cerithioidea) as determined by partial 18s rDNA sequences
Phylogenetic analyses of partial sequences spanning approximately 450 nucleotides near the 5’end of the 18s rDNA strongly support the monophyly of Apogastropoda and its constituent clades, Caenogastrooda and Heterobranchia and exclude Architaenioglossa, which does not emerge as a clade in any of the analyses. Expand
Neogastropod Phylogeny: A Molecular Perspective
Investigation of the origin and evolution of the gastropod order Neogastropoda using an iterative, two gene approach to phylogeny reconstruction revealed similarities in genetic differences between orders of mammals, but are only slightly greater than differences between genera of penaeid shrimp. Expand
Molecular systematics of the major lineages of the Gastropoda
By virtue of their abundance and diversity in the Recent fauna, gastropods have been used in studies spanning numerous biological disciplines, including ecology, physiology, developmental biology, population genetics, biodiversity, biomechanics, biogeography, and molecular evolution. Expand
Review of western Atlantic species of cocculinid and pseudococculinid limpets, with descriptions of new species (Gastropoda: Cocculiniformia)
Western Atlantic members of the limpet families Cocculinidae and Pseudococcuiinidae are reviewed and previously described species are allocated to current genera, and new species are described. Expand
Phylogeny and relationships of pleurotomariid gastropods (Mollusca: Gastropoda): an assessment based on partial 18S rDNA and cytochrome c oxidase I sequences.
The phylogenetic position of the ancient family Pleurotomariidae within the Molluscan class Gastropoda, as well as the relationships of its Recent genera and species, were assessed using anExpand
