20.500.12556/DiRROS-23967 Bottom trawling and environmental variables drive the biodiversity of mediterranean demersal assemblages Marine ecosystems are healthy with a high degree of biodiversity. Assessing how factors affect spatial and temporal patterns of biodiversity is an essential task for the Ecosystem Based Management approach. In this work, we investigated the effect of fisheries disturbance and ocean variables in determining α- and β-diversity of Mediterranean demersal assemblages. Generalized additive mixed models were used to explain the spatio-temporal variability of diversity indices from 2014 to 2020 in three Mediterranean subregions as a function of covariates. An in-depth analysis also made it possible to decouple the effects of bottom trawling from the other covariates. The results show that several fishing activities and environmental variables influence biodiversity, but the direction of change depends on the subregion considered. Bottom trawling instead has a quasi-linear erosion effect on α- and β-diversity in all areas. Valuable commercial species and threatened rays and sharks importantly characterized the sites with low fishing impact. Results are a step towards the development of conservation and management strategies, particularly in the context of the Marine Strategy. biodiversity fishing Mediterranean sea marine strategy biološka raznovrstnost ribištvo Sredozemsko morje morska strategija true false true Angleški jezik Slovenski jezik Neznano 2025-10-28 12:32:18 2025-10-28 12:32:18 2025-10-29 03:55:29 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Soavtorji: Ivano Vascotto, Diego Panzeri, Igor Celić, Cosimo Solidoro, Tomaso Fortibuoni, Saša Raicevich, Simone Libralato; Opis vira z dne 28. 10. 2025; Str. 1-16 [art. no.] ǂ27188 Vol. 15 Jul. 2025 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 2025-05-05 2025-07-16 2025-07-26 574 2045-2322 10.1038/s41598-025-12258-2 255061507 https://doi.org/10.1038/s41598-025-12258-2 1 c511915b-b3f1-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35597 RAZ_Agnetta_Davide_2025.pdf RAZ_Agnetta_Davide_2025.pdf 1 8B18176E62671B90C7BBBCCDF0156993 493f312d0c654cd0d8f4ffe4bfad0bce7808f1ff43026a2ea0befa16734c03df efdee567-b3f1-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35598 Nacionalni inštitut za biologijo 0 0 0
