In the Mediterranean Sea, bivalve genus Pinna is represented by two species: endemic nobilis and (sub)tropical Atlantic rudis. P. rudis generally less common mostly restricted to warmer regions of western Mediterranean. However, since a mass mortality event, caused pathogen infection, has brought brink extinction, records have increased in several regions, where it had not been previously observed. This paper reports on presence individuals Ligurian northernmost reach this species become increasingly between 2021 2023, with total 28 new from seven localities along coast. The size their estimated growth rate (3.6 cm·a−1) indicated that recruitment event most likely took place summer 2020, when was no longer present area. Our observations suggest success following decline nobilis. considering thermophilic nature rudis, all likelihood, ongoing water warming playing crucial role successful establishment Sea. A full understanding recent range expansion far being achieved, whether will be able fulfil ecological difficult predict. Large scale monitoring remains only effective way know about future Pinnids

Pinna nobilis, endemic to the Mediterranean Sea, has been experiencing a gradual population decline over recent decades due anthropogenic pressures on its ecosystems. However, since 2016, populations have suffered significant reductions because of pathological issues affecting species across all habitats. Aquaculture techniques support limited natural recruitment P. nobilis efforts is examined. Artificial substrates for larval attachments in aquaculture infrastructures promote survival juveniles that further enhanced through protected pre-growing “nursery” farming conditions. Specific spat collectors were placed 2 cage-fish farms SW Amvrakikos Gulf. The harvested spats from transferred pre-grow trays hanged long line farm mussel acting as “nursery”, avoiding predation and any human accidentally disturbance. growth 12 (shell length 38.1 ± 9.2 mm) captivity (31 October 2023–15 March2023) was investigated.

Abstract Marine ecosystems are facing a dramatic loss of biodiversity worldwide, together with widespread collapse habitats and their functionality. In this context, Citizen Science (MCS) can be powerful tool to monitor these changes over time. The flowering very well-structured international projects is strengthening the scientific credibility MCS data, especially when data collected after specifically designed training programs shared in public user-friendly repositories. Here we present new perspective on use Mediterranean area, along main benefits for stakeholders (i.e., diving centers, trainers, policymakers) users divers), resumed three pillars: Pillar I – as site valorization; II career opportunity graduated students; III business centers. frame Quintuple Helix Approach, which there strong need socioecological transition society economy, show how win-win-win solution all actors involved, providing vision highly qualified job opportunities sector.

Abstract The Pinna nobilis , a Mediterranean mollusc, has suffered population declines due to massive mortality event associated with various factors including the parasite Haplosporidium pinnae . Some populations show resilience, possibly local environmental conditions. In this study, molecular multiplex PCR method was developed using species‐specific primers targeting Internal Transcribed Spacer (ITS) regions of P. and rudis allowing accurate species identification hybrid detection. Samples from areas were analysed, putative hybrids individuals five other bivalve species. DNA isolated, ITS amplified sequenced, phylogenetic analyses confirmed differentiation primer specificity. multiplex‐PCR successfully identified their based on distinct amplicon patterns. This study highlights value tools in conservation, especially for monitoring managing hybridization, supporting effective biodiversity conservation strategies.
