ABSTRACT

Despite growing recognition of nature's impact on mental health, its specific effects on adolescents remain unclear. This gap hinders effective strategies for youth well-being in a world facing increasing environmental pressures. This study directly investigates the connections between coastal environments and subjective well-being in adolescents. We explore how interactions with coastal landscapes and associated cultural ecosystem services contribute to both personal and social dimensions of well-being in a sample of 202 adolescents (16 and 17 years old) from Sardinia, Italy. Our findings reveal a beneficial impact of coastal experiences, promoting positive affect, social integration, and physiological well-being. However, human pressures on these environments can lead to negative affect, while fostering a sense of social contribution. This research highlights the complex interplay between coastal environments, human impacts, and teenagers' well-being. Understanding these links empowers planners to craft coastal management strategies that balance adolescents' well-being with the long-term sustainability of coastal regions.

ABSTRACT

The fan mussel, Pinna nobilis, represents the largest bivalve endemic to the Mediterranean Sea. Since 2016, dramatic mass mortality of this species has been observed in several areas. The first surveys suggested that Haplosporidium pinnae (currently considered species-specific) was the main etiological agent, but recent studies have indicated that a multifactorial disease may be responsible for this phenomenon. In this study, we performed molecular diagnostic analyses on P. nobilis, P. rudis, and bivalve heterologous host species from the island of Sardinia to shed further light on the pathogens involved in the mass mortality. The results support the occurrence of a multifactorial disease and that Mycobacterium spp. and H. pinnae are not necessarily associated with the illness. Indeed, our analyses revealed that H. pinnae is not species-specific for P. nobilis, as it was present in other bivalves at least three years before the mass mortality began, and species of Mycobacterium were also found in healthy individuals of P. nobilis and P. rudis. We also detected the species Rhodococcus erythropolis, representing the first report in fan mussels of a bacterium other than Mycobacterium spp. and Vibrio spp. These results depict a complicated scenario, further demonstrating how the P. nobilis mass mortality event is far from being fully understood.
