“…The transcriptome or RNA expression levels in these organisms are also being explored with the goal of understanding the timing of transcription, translation, and protein secretion as it pertains to the events occurring in the biomineralizing matrix . What has emerged from these studies…”

“…The mollusk, of the phyla Lophotrochozoa, is one of the most diverse groups on Earth (>50 000 species) that creates a protective outer shell that has a high degree of organization, much more so than bone, and this system has been intensely studied for several decades . In most bivalve mollusks, the shell consists of three layers (Figure ): 1) the periostracum, which is a thin organic coating or “skin” comprising the outermost layer of the shell; 2) the prismatic layer, the outermost mineral layer of the shell that comprises organized parallel rods of single crystal calcite, a calcium carbonate polymorph; 3) nacre layer, or the innermost mineral layer of the shell that comprises hexagonal tablets of single crystal aragonite, a calcium carbonate polymorph, that are arranged in a “brick‐and‐mortar” organization . Both the prismatic and nacre mineral particles are coated with a protein‐containing film or layer that is termed the framework layer and this will be discussed in more detail below .…”

There are over 62 different biominerals on Earth and a diverse array of organisms that generate these biominerals for survival. This review will introduce the process of biomineralization and the current understanding of the molecular mechanisms of mineral formation, and then comparatively explore the representative secretomes of two well-documented skeletal systems: vertebrate bone (calcium phosphate) and invertebrate mollusk shell (calcium carbonate). It is found that both skeletal secretomes have gross similarities and possess proteins that fall into four functional categories: matrix formers, nucleation assisters, communicators, and remodelers. In many cases the mineral-associated matrix former and nucleation assister sequences in both skeletal systems are unique and possess interactive conserved globular domains, intrinsic disorder, post-translational modifications, sequence redundancy, and amyloid-like aggregation-prone sequences. Together, these molecular features create a protein-based environment that facilitates mineral formation and organization and argue in favor of conserved features that evolve from the mollusk shell to bone. Interestingly, the mollusk shell secretome appears to be more complex compared to that of bone tissue, in that there are numerous protein subcategories that are required for the nucleation and organization of inner (nacre) and outer (prismatic) calcium carbonate regions of the shell. This may reflect the organizational and material requirements of an exoskeletal protective system.

“…Scientific literature about P. nobilis has been retrieved from multiple databases related to cross-disciplinary research, which allow an in-depth exploration of specialized subfields within a certain academic or scientific discipline, such as Web of Science (http:// www.webofknowledge.com/), Science Direct (http://www.sciencedirect.com) and Google Scholar (http://scholar.google.com). Scientific literature until September 2018 was selected; according to Basso et al (2015), different combinations of the keywords "Pinna nobilis", "pen shell" and "fan mussel" were used.…”

“…There is scientific evidence that this species is a good indicator of changes in marine ecosystems providing information on biotic response to anthropogenic pressures (Alomar et al 2015). P. nobilis supplies some ecosystem services by retaining a large amount of organic matter from the water column, hosting other species, working as a hard substrate in the soft-bottom seafloor, providing a surface that can be colonized by other benthic species, improving the local biodiversity (Basso et al 2015), and attracting scuba-divers (e.g. tourism and recreation) (Marrocco et al 2018).…”

“…According to Basso et al (2015), currently gaps in the knowledge of the species occurrence and behavior preclude the formulation of effective conservation strategies for P. nobilis. Studies on distribution and conservation status of this endangered species should be evaluated in different habitats, in different regions of the Mediterranean Sea and on different time scales (e.g., long-term studies) to identify probable, common, or peculiar sources of mortality within the Mediterranean Sea (Basso et al 2015). For this reason, here we provide a systematic review on the occurrence of P. nobilis, using and combining different sources of information such as scientific and grey literature, NATURA 2000 geodata and citizen science records.…”

This research investigates the occurrence of Pinnanobilis (Linnaeus, 1758) in the Mediterranean Sea, where it is an endemic and the largest bivalve species. Such a species is protected under the European Council Directive 92/43/EEC since 1992, being exposed to anthropogenic impacts. The distribution of this species has been known, in the past, only from reports in scientific literature. Presently, the concerns, threats and risks for P.nobilis are increasing and a more detailed mapping of the actual distribution from a largest to a local spatial scale is essential for the implementation of monitoring, management and conservation actions. Here we provide a systematic review on the occurrence of P.nobilis, employing and combining different sources of information, such as scientific and grey literature, NATURA 2000 geodata and citizen science records. The methodological approach is a pilot test based on a scaling down of the geographical area of study, from the whole of the Mediterranean Sea to the Italian and Apulian coastline (South-East Italy); accordingly, the above mentioned sources of data have been gradually included. The results show that the combination of multiple sources of information provide a more exact determination of the species distribution at a local scale, identifying sites where in-depth actions are required to ensure the species conservation and restoration. Also, the IUCN has recently underlined that the conservation of P.nobilis has become a difficult challenge, so that each of the spatial scales for the investigation is crucial to enable a better preservation and conservation of the species in the Mediterranean Sea.

1. Pinna nobilis is an endemic bivalve of the Mediterranean Sea, and a vulnerable species registered as endangered and protected under the European Council Directive 92/43/EEC and Barcelona Convention. 2. In early autumn 2016, a mass mortality event impacted P. nobilis populations in the south-western Mediterranean Sea, including the Balearic Islands. At the time of this study, P. nobilis still maintained high population densities along the Balearic coasts (Western Mediterranean).3. This study evaluated the connectivity of P. nobilis post-larvae and adults in seagrass habitats around the Balearic Islands and identified its source and sink populations.These objectives were reached through a multidisciplinary approach including population genetics (10 microsatellites) and hydrodynamic modelling. 4. High genetic diversity was found and significant genetic differentiation (inferred by fixation index F ST ) was detected between post-larvae samples, but not between adult populations. Significant genic and genotypic differentiation was recorded for adults and post-larvae.5. This pattern was confirmed by correspondence analysis using allele frequencies.The genetic connectivity pattern was consistent with marine currents and dispersal models.6. This work not only improves knowledge of the P. nobilis gene pool in south-west Mediterranean populations and their connectivity patterns, but is also crucial to help evaluate the possibility of recovery from source populations and the possibility of restocking programmes, as well as provide a solid base to establish effective marine reserve networks.
