Phylogenetic relationships within Pectinidae (Bivalvia, Pteriomorphia) have been investigated primarily for Pacific and Western Atlantic or commercially valuable taxa. Most molecular phylogenetic studies have revealed monophyly of pectinid bivalves but interrelationships of the different clades are still inconsistent. However, non-commercial European Pectinidae has mostly been neglected in earlier investigations and therefore the evolution and radiation of the European Pectinidae is poorly… 

Evolutionary relationships of the Tehuelche scallop Aequipecten tehuelchus (Bivalvia: Pectinidae) from the south-western Atlantic Ocean

The phylogenetic analysis indicates that the two putative subspecies of the Tehuelche scallop together with F. felipponei form a monophyletic clade, without differentiating at the specific level, however, further analysis using genes with faster evolution rate are needed to corroborate it.

Complex mitogenomic rearrangements within the Pectinidae (Mollusca: Bivalvia)

Examination of the mitochondrial genome of a member of Chlamydinae, Mimachlamys varia, reveals incongruities between phylogenies based on mitochondrial protein-coding versus rRNA genes within the Pectinidae, suggesting that locus sampling affects phylogenetic inference at the scale of the family.

Impact of habitat and life trait on character evolution of pallial eyes in Pectinidae (Mollusca: bivalvia)

Compared eyes within the major subgroups of Pectinidae are compared, indicating a tendency towards a taxon-/clade-specific evolution in respect to characters such as the cornea and lens while depth specific adaptations occur mainly in the light sensitive compartments of the retina.

The Black Sea Flexopecten species-complex (Mollusca: Bivalvia: Pectinidae): Shell morphology and 16S rDNA variation

It is concluded that the Black Sea form represents an eastern extension of the Mediterranean scallop F. glaber, characterized by a significant lack of genetic variability when compared to the Mediterranean form, although it does contain new haplotypes not found in that species.

Unveiling the unknown phylogenetic position of the scallop Austrochlamys natans and its implications for marine stewardship in the Magallanes Province

This study provides integrative evidence to alert the current fishery management and the need for further conservation studies and presents a complete review of the historical identification of the Magallanes scallop and a multi-locus molecular phylogeny which allowed it to recover the phylogenetic position of A. natans.

Phylogeography in an “oyster” shell provides first insights into the genetic structure of an extinct Ostrea edulis population

The historical phylogeography of Ostrea edulis was successfully depicted in its native range for the first time using ancient DNA methods on dry shells from museum collections and revealed a temporally stable population genetic pattern over the past 150 years despite large-scale translocations.

The first transcriptomic resource for the Antarctic scallop Adamussium colbecki

Genetic analysis identifies the Ostrea stentina/aupouria/equestris oyster species complex in Hawai‘i, and resolves its lineage as the western Pacific O. equestris

This study expands the known range of O. equestris by providing the first verification of its occurrence in Hawai’i by sequencing two partial gene fragments and placing Hawai‘i Ostrea alongside samples from China, Japan, and New Zealand.

Seasonal antioxidant and biochemical properties of the Northern Adriatic Pecten jacobaeus

The wintermaxima of TAS and thiobarbituric acid reactive substances TBARS in relation to summer maxima of glutathione peroxidase and superoxide dismutase in digestive glands indicate to a decrease in antioxidant defense during cold months, and are related to the accumulation of lipid peroxidation products in digestive gland of scallops.



Phylogeny and Biogeography of Pholadid Bivalve Barnea (Anchomasa) with Considerations on the Phylogeny of Pholadoidea

The analysis confirms that Barnea s.s. and B. (Umitakea) are its closest relatives and that the morphological similarities to other taxa are mainly due to plesiomorphies, and gives suggestions for the reconstruction of the phylogeny of the superfamily Pholadoidea.


Although the object of phylogenetics and taxonomy should be discriminated, molecular phylogenetic studies thus provide criteria to see through convergence at various levels and will contribute much to improve existing classification systems.

Phylogenetics of American scallops (Bivalvia: Pectinidae) based on partial 16S and 12S ribosomal RNA gene sequences

A phylogenetic analysis of the 12S and 16S ribosomal RNA genes in nine species of pectinids belonging to six genera living along American coasts indicates that Crassadoma is polyphyletic, and cementation to the substrate as a life habit could have appeared independently in two geographic chlamydinid lineages.

Convergent and parallel evolution in life habit of the scallops (Bivalvia: Pectinidae)

This analysis indicates that byssal attaching gave rise to significantly more of the transitions than any other life habit and that the cementing and nestling classes are only represented as evolutionary outcomes in the authors' phylogeny, never as progenitor states.

Phylogeny of families in the Pectinoidea (Mollusca: Bivalvia): importance of the fossil record

Evidence from morphology, the fossil record, and molecular genetics indicates that the family Spondylidae originated in the Middle Jurassic from an ancestor within the Pectinidae, possibly the genus SpondYLopecten, which was already present in the Late Triassic.

Molecular Data from the 16S rRNA Gene for the Phylogeny of Pectinidae (Mollusca: Bivalvia)

Chlamys are polyphyletic and do not support the assignment of these species to the two subfamilies Chlamydinae and Pectininae, and the minimal genetic distance between P. maximus and P. jacobeus suggests that they could belong to the same species.
