“…Although ITS sequences have been successfully used in phylogenetic studies of other mussels, such as shallow water Perna spp. (Wood et al, 2007), studies using ITS from Bathymodiolus spp. required an additional cloning step as part of the amplification process (Jollivet et al, 1998;Olu-Le Roy et al, 2007), presumably to overcome the issue of multiple copies.…”

Genetic connectivity studies can inform the design of mitigation strategies used in environmental management. However, the expense of developing species-specific molecular markers and collecting samples at appropriate spatial and temporal scales can be prohibitive. Using archived material and existing molecular markers may provide a cost-effective way to assess population connectivity. Genetic connectivity studies are increasingly in demand in the deep sea in response to mounting anthropogenic pressures, including seafloor massive sulfide (SMS) mining. The feasibility of using archived material was assessed using the New Zealand-endemic vent mussel Gigantidas gladius, which inhabits areas licensed for the prospecting phase of SMS mining. Four molecular markers were tested, but only one (mitochondrial COI) provided suitable sequences. Of 942 specimens, only 150 individuals were informative, largely due to poor tissue quality of archived samples. Seven populations spanning the distributional range of G. gladius were assessed. The results indicate that G. gladius has high levels of gene flow among sites 10 to 100 s km apart and limited genetic structure. Haplotypic diversity was not equally distributed among populations, with lower diversity for the Macauley Volcano population at the northern extent of the species distribution and greater diversity within central populations. Migrant exchange was also greatest between central populations, with one population at Rumble V Seamount appearing important in terms of maintaining genetic diversity within the Kermadec Volcanic Arc region. However, interpretation of the results should be viewed with caution as small sample sizes may have limited the ability to detect genetic structure. Despite these limitations, mitigation strategies that protect areas of seabed from mining activities should consider the genetic vulnerability of the population at the northern edge of the species' distribution and the significance of certain central populations.

“…Six additional COI sequences were downloaded from GenBank: two sequences from X. atratus (AB298598, AB298599) (Kimura et al 2007 submitted), one sequence from X. pulex (DQ917582) (Wood et al 2007), and three sequences from Mytilus edulis, Mytilus galloprovincialis and Modiolus areolatus The mussel Xenostrobus securis 2093 (DQ917606, DQ917605 and DQ917604, respectively) (Wood et al 2007). Three 18S sequences from the latter species were also included in the analysis (L33448, L33451 and AF124210, respectively) (Wood et al 2007).…”

The mussel Xenostrobus securis: a well-established alien invader in the Ria de Vigo (Spain, NE Atlantic)

Biological and habitat characterization of the non-indigenous invasive species Xenostrobus securis was undertaken in the Ria de Vigo. This study included genetic identification of mussel samples collected from introduced and endemic areas, and the assessment of mussel size, population abundance, geographic distribution, pathological condition, and sediment composition of substrata type. The mussel had a marked patchy distribution, being more abundant in brackish sites with fine sediments and high organic matter content. Pathological analysis revealed that X. securis does not play any role as vector for introducing allochthonous pathogens in the Ria de Vigo. Nevertheless, depending on its invasiveness potential, the mussel could be a key host favouring spreading and epizootic outbreaks of marteliosis which is known to be harmful for local bivalve populations. Phylogenetic analyses of the COI gene placed all the resulting sequences in a clade within the genus Xenostrobus and its phylogeny congruent with an Australian/Pacific origin. The COI tree suggests two historical introductions in European waters. One of these invasions seems to have started in Galicia, moving from there towards Italy and France, while the geographical spread of the second invasion cannot be deciphered, although the Australian/Pacific origin of this invasion seems very possible. The 18S network is congruent with one invasion starting in Galicia or in Italy, as the Australian haplotype is closely related to the haplotype found in these areas. Several hypotheses accounting for the colonization history of this species in Galician waters are discussed.

“…Secondly, mtDNA sequence-based phylogenetic analyses unambiguously confirm its taxonomic status as a member of the Indo-Pacific Crassostrea. Our inference is reasonable because 1) the molecular markers (i.e., partial cox1 and rrnL genes) used in this study have been widely and successfully used in phylogenetic reconstructions of marine bivalves including scallops (Mahidol et al 2007;Puslednik and Serb 2008), mussels (Wood et al 2007) and clams (Kappner and Bieler 2006;Chen et al 2011); and 2) molecular phylogeny inferred in this study unambiguously agrees with the morphological taxonomy of true oysters (i.e., Ostreidae family), particularly the well-supported monophyly of Indo-Pacific Crassostrea, American Crassostrea, Saccostrea and Ostrea. Additionally, studies of the morphological characteristics of the shells of C. zhanjiangensis and other Indo-Pacific Crassostrea species have shown that there are several distinctive traits that distinguish the new species from other known species.…”

-Cupped oysters (Ostreidae, genus Crassostrea) occupy nearshore marine and estuarine habitats worldwide, providing many ecosystem goods and services as well as being a commercially important group of bivalves. In this study, the species identification of an "adulterant" oyster with small body size, which is often misidentified as a "young individual" of other sympatric species, including C. sikamea and C. hongkongensis, was determined for the first time, based on molecular markers (partial mitochondrial cox1 and rrnL genes), phylogenetic analysis, and morphometric approaches. This novel species, C. zhanjiangensis, commonly known as the "cat ear oyster" in Guandu (a famous estuarine oyster farming region of Zhanjiang, Guangdong Province, China), appears to potentially influence the efficiency of C. hongkongensis spat collection due to niche competition on spat collection devices. Phylogenetic analyses confirm its status as the most basal taxon of the Indo-Pacific Crassostrea. A comparative study of the shell characteristics of C. zhanjiangensis, and other Crassostrea species revealed several distinctive morphological traits, including a generally smaller body size, a deeply cupped left valve, and a right valve that is convex in adults but flat in young individuals. Other distinctive features of the new species include life cycle traits that are unique compared with the sympatric C. hongkongensis and C. sikamea species, such as a higher growth rate in the fast growth phase after settlement, followed by a significantly slower growth rate and mass mortality during subsequent life stages. This study provides the basic information necessary for further ecological and population genetic studies on this new species.
