Special Issue Information

Dear Colleagues,

There are few animals as versatile as molluscs. In terms of the number of described species, they are the second largest phylum after arthropods. They have found their way into almost every ecosystem on the planet, including the most arid deserts and the deepest ocean trenches.

Molluscs can become pests as invasive species in some places and vectors of tropical diseases in others. In the sea, they are one of the best-represented invertebrate groups in all environments and one of the best-known thanks to their shells, or their striking appearance when they do not have a shell.

They have been studied for a long time due to their high biological, economic, and pharmaceutical interest.

The immense plasticity of molluscs’ body shape, with no other animal equivalent, offers an infinite number of possibilities for evolutionary and adaptive patterns. They have been used to establish fundamental principles of evolutionary biology mechanisms, global biogeography, and past mass extinctions. The eight distinct living taxonomic classes of molluscs are each unambiguously monophyletic; however, significant debate remains about the topology of the phylogenetic relationships among those eight branches. Results from different molecular phylogenetic approaches are quite different, for example, molecular phylogenetic analyses with few gene fragments but high taxon sampling, transcriptomic approaches with intermediate data and limited taxon sampling, or true phylogenomic analyses using genome assemblies that have high data volume but very low taxon sampling. More intensive work within specific clades of molluscs, and more broadly in other organismal groups, has repeatedly reaffirmed that insufficient taxon sampling can lead to inaccurate phylogenetic reconstruction, especially for complex groups.

In recent years, sequencing has become more accessible and affordable. This has favored the study of non-model organisms such as molluscs, for which the number of sequencing-related publications is rapidly growing. The analysis of genomic and transcriptomic data has become a fundamental part of many research initiatives.

We hope that the articles in this Special Issue will show the latest advances in the large group represented by marine molluscs, with the hope of giving the reader an opportunity to achieve a global update on how phylogeny and evolutionary biology are progressing in this group, hopefully to get a glimpse of where it is headed.

The population genetics of Patella ferruginea Gmelin, 1791, an endangered limpet endemic to the western Mediterranean, has been analysed using 11 polymorphic microsatellite markers on 533 individuals from 18 localities throughout its distribution area. The results showed a deficit of heterozygotes, denoting a certain degree of inbreeding, and, with an overall FST of 0.004, a low level of genetic variability among localities. These data indicate that the species is distributed as a metapopulation (an assemblage of discrete local populations with migration among them) along most of the species’ range. Moreover, 99% of the variability observed was within populations, with only 0.41% accounting for between-population variability. No pattern of isolation-by-distance was found, and 35.5% of the individuals were recognised as migrants. Altogether, the findings indicate that most of the populations studied are connected to each other to some extent and that larvae of the species show a higher dispersal capacity than previously assumed. The exchange network does not follow a clear direction but rather shows a chaotic pattern attributed to stochastic factors resulting from the complex interaction of biotic and abiotic factors. This pattern indicates the lack of strong barriers to dispersal in the study area and permeable barriers that do not limit population connectivity. A relatively high level of self-recruitment and occasional stochastic dispersal events at variable distances are also evidenced by the analyses. Currently, marine protected areas (MPAs) safeguard the benthic adults but not the larval phase of the species. Considering our results, the conservation of P. ferruginea should be based on a holistic approach in which the protection of its habitats extends from the benthic to the pelagic zones, which will help maintain the larval pool and promote larval dispersal and settlement and, ultimately, gene flow. Lastly, conservation efforts must prioritise the survival of the extant populations of P. ferruginea, both within and outside MPAs, over measures that require the manipulation or translocation of specimens.

The larvae of the marine gastropod Lophocochlias parvissimus are meroplankton that spend part of their lives as plankton that disperse and drift in the water column before settling on the sea floor. Two individuals of L. parvissimus larvae were sampled by the Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) from the Central Indian Ridge of the southwestern Indian Ocean in 2018 and 2019. We generated the first mitochondrial sequences for L. parvissimus, which will provide valuable genetic insight into the evolution of these organisms. In this study, we have determined that the mitogenome of L. parvissimus was 13,575 bp in length, consisting of 13 protein-coding genes, 18 tRNAs, and two rRNAs. Our work provides a new insight into the dispersal of L. parvissimus and previously missing components to the general understanding of the evolution of Truncatelloidea (Subclass Caenogastropoda).

The geoduck clam is a high-value species in South Korea. However, the molecular and morphological characteristics of geoduck clams from the southern coast of South Korea remain unexamined. The accurate identification of native geoduck clams is crucial for their conservation and management. Therefore, this study used a combination of molecular and morphological analyses to characterize native geoduck clams from the southern coast of South Korea. Based on complete mitochondrial genome and morphological analyses, the native species of geoduck clam from this study area was identified as Panopea sp. 1. The complete mitochondrial genome sequencing of Panopea sp. 1 revealed a total of 16,225 bp in length with 37 genes (13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes). It was also shown that Panopea sp. 1 belongs to the family Hiatellidae based on a phylogenetic analysis tree with 11 bivalve species. In particular, Panopea sp. 1 is closely related to three other Panopea species (Panopea sp., Panopea abrupta, and Panopea japonica). The phylogenetic analysis correlated with the morphological analysis. Overall, this is the first reliable record of Panopea sp. 1 in South Korea. These findings provide a basis for accurate species identification based on morphological characteristics and complete mitochondrial genome sequencing. Full article
