To re-evaluate the relationships of major bivalve lineages, we amassed detailed morpho-anatomical, ultrastructural and molecular sequence data for a targeted selection exemplar bivalves spanning phylogenetic diversity class. We included 103 species (up to five markers) also analysed subset taxa with four additional nuclear protein-encoding genes. Novel as well historically employed morphological characters were explored, systematically disassembled widely used descriptors such gill stomach...
Some 1,048 names at the rank of subtribe, tribe, subfamily, family and superfamily have been proposed for Recent fossil bivalves. All are listed in a nomenclator giving full bibliographical reference, date publication, type genus, their nomenclatural availability validity under International Code Zoological Nomenclature. Another 274 names, established categories above family-group separately. A working classification attempts to group all bivalve into single system based on current...
Bivalves are an ancient and ubiquitous group of aquatic invertebrates with estimated 10 000-20 000 living species. They economically significant as a human food source, ecologically important given their biomass effects on communities. Their phylogenetic relationships have been studied for decades, unparalleled fossil record extends from the Cambrian to Recent. Nevertheless, robustly supported phylogeny deepest nodes, needed fully exploit bivalves model testing macroevolutionary theories, is...
Bivalvia has been the subject of extensive recent phylogenetic work to attempt resolving either backbone bivalve tree using transcriptomic data, or tips morpho-anatomical data and up five genetic markers. Yet first approach lacked decisive taxon sampling second failed resolve many interfamilial relationships, especially within diverse clade Imparidentia. Here we combine dense with 108 deep-sequenced Illumina-based transcriptomes provide resolution in nodes that required additional study. We...
The largest Recent family of Bivalvia, the marine Veneridae with approximately 800 species, comprises one least understood and most poorly defined molluscan taxa, despite including some economically important abundant bivalves, for example quahog, Pismo clams, Manila clams. A review previous phylogenetic analyses superfamily Veneroidea (Veneridae, Petricolidae, Glauconomidae, Turtoniidae, Neoleptonidae) within shows minimal taxon sampling leading to weak conclusions few supported...
A new species of vermetid gastropod belonging to the genus Novastoa Finlay, 1926, N. rapaitiensis sp. nov., is described from French Polynesia and Great Barrier Reef, based on morpho-anatomical molecular data, increasing recognized extant diversity this five six species. The characterized by largest operculum in date, with a conspicuous spindle-shaped mammilla that readily distinguishes its congeners. Based available members studied populations nov. are interpreted as single species,...
Species distribution models (SDMs) are numerical tools that combine observations of species occurrence or abundance with environmental estimates. They used to gain ecological and evolutionary insights predict distributions across landscapes, ...Read More
Systematic research on bivalved molluscs (Mollusca: Bivalvia = Pelecypoda) is briefly reviewed in an introduction to a series of papers focusing seven the larger branches bivalve tree. These are presented attempt summarize current knowledge, stimulate new and highlight needs for future focus. A revised classification extant families (with synonyms included subfamilies) presented, based information compiled from latest palaeontological, morphological molecular data.
Widespread sampling of vertebrates, which comprise the majority published animal mitochondrial genomes, has led to view that gene rearrangements are relatively rare, and orders typically stable across major taxonomic groups. In contrast, more limited within Phylum Mollusca revealed an unusually high number order arrangements. Here we provide evidence lability molluscan genome extends family level by describing extensive changes have occurred Vermetidae, a sessile marine gastropods radiated...
The family Omalogyridae comprises some of the smallest known marine snails. Like all micromolluscs, they have been historically neglected and are underrepresented in faunistic surveys. Based on a few focused studies family, 15 valid omalogyrid species were previously recognised Indian Pacific Oceans. To these, we add 3 new based morphological analysis material dry collection Natural History Museum Los Angeles County, applying light scanning electron microscopies. species, Ammonicera mcleani,...
Mussels (Mytilida) are a group of bivalves with ancient origins and some the most important commercial shellfish worldwide. Mytilida consists approximately 400 species found in various littoral deep-sea environments, part higher clade Pteriomorphia, but their exact position within has been unstable. The multiple adaptive radiations that occurred Pteriomorphia have rendered phylogenetic classifications difficult uncertainty remains regarding relationships among families. To address this...
Analyses of evolutionary dynamics depend on how phylogenetic data are time-scaled. Most analyses extant taxa assume a purely bifurcating model, where nodes calibrated using the daughter lineage with older first occurrence in fossil record. This contrasts budding, younger occurrence. Here, we use extensive record bivalve molluscs for large-scale evaluation branching models affect macroevolutionary analyses. We time-calibrated 91% nodes, ranging age from 2.59 to 485 Ma, phylogeny 97 families....
Although the majority of metazoan mitochondrial genomes (mtDNAs) contain same 37 genes, including 22 encoding transfer RNAs (tRNAs), recognition orthologs is not always straightforward. Here we demonstrate that inferring tRNA among taxa by using anticodon triplets and deduced secondary structure can be misleading: through a process duplication mutation in triplet, remolded leucine (L UUR ) genes have repeatedly taken over role isoaccepting L CUN tRNAs within mtDNA. In present work, data from...
A book with the luster and allure of its subject, Pearls is most spectacular volume ever produced on this prized gem. Blending history, science, jeweler's art to celebrate these natural treasures - as in Abrams' hugely successful Amber lavishly illustrated volume, shimmering new color photography archival images, traces cultural history pearls around world.

Ultrastructural features of the ovotestes, spermatogenesis, and mature sperm are described for three galeommatid bivalves, Divariscintilla yoyo, troglodytes, Scintilla sp., from stomatopod burrows in eastern Florida. All species yielded similar results except with respect to dimensions. The ovotestis contains types somatic cells within testicular portion: flattened myoepithelial defining outer acinal wall; underlying pleomorphic follicle containing abundant glycogen deposits; scattered,...
Bivalves share many of the "deeper" questions with other molluscan groups - issues such as their origin and sister-group relationships within Mollusca, suitability to explore molecular data in a "known" fossil framework. Other are more specific bivalves, group that radiated so successfully nowadays predominantly specializes infaunal sessile epifaunal suspension feeders. This paper highlights explores unanswered questions, from seemingly trivial mundane (e.g., how species actually out...
Identifying natural groups within the caenogastropod family Vermetidae has proven challenging. The sessile lifestyle of vermetids, with associated xenomorphically distorted, overgrown and corroded shells, resulted in a long confused taxonomic history based primarily on adult shell characters. In this study, we use morphological, anatomical molecular data to clarify systematics phylogenetic relationships genus Dendropoma s.l. We assess generic names previously used group for availability...
