20.500.12556/DiRROS-19589 Tracking a mass mortality outbreak of pen shell Pinna nobilis populations a collaborative effort of scientists and citizens A mass mortality event is devastating the populations of the endemic bivalve Pinna nobilis in the Mediterranean Sea from early autumn 2016. A newly described Haplosporidian endoparasite (Haplosporidium pinnae) is the most probable cause of this ecological catastrophe placing one of the largest bivalves of the world on the brink of extinction. As a pivotal step towards Pinna nobilis conservation, this contribution combines scientists and citizens’ data to address the fast- and vast-dispersion and prevalence outbreaks of the pathogen. Therefore, the potential role of currents on parasite expansion was addressed by means of drift simulations of virtual particles in a high-resolution regional currents model. A generalized additive model was implemented to test if environmental factors could modulate the infection of Pinna nobilis populations. The results strongly suggest that the parasite has probably dispersed regionally by surface currents, and that the disease expression seems to be closely related to temperatures above 13.5 °C and to a salinity range between 36.5–39.7 psu. The most likely spread of the disease along the Mediterranean basin associated with scattered survival spots and very few survivors (potentially resistant individuals), point to a challenging scenario for conservation of the emblematic Pinna nobilis, which will require fast and strategic management measures and should make use of the essential role citizen science projects can play. mass mortality endoparasites Pinna nobilis true false true Angleški jezik Latinski jezik Neznano 2024-07-20 04:02:10 2024-07-24 09:22:03 2024-07-25 04:14:44 0000-00-00 00:00:00 2019 0 0 Nasl. z nasl. zaslona; Opis vira z dne 14. 10. 2019; str. 1-11 Vol. 9 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2019-09-16 574.5 2045-2322 10.1038/s41598-019-49808-4 5191247 https://www.nature.com/articles/s41598-019-49808-4 1 5a1919d5-462b-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27042 RAZ_Cabanellas-Reboredo_Miguel_2019.pdf RAZ_Cabanellas-Reboredo_Miguel_2019.pdf 1 6B9BCCDB862F8F2798B05241C12EBB99 c1cff1affdb6b6c28c53b664ea92d1c75d248774fd68c6eff6674c23b2df8b84 716454d1-497e-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27252 Nacionalni inštitut za biologijo 0 0 0
