A. auteur aut IRD Parravicini V. auteur aut IRD text journalArticle eng text/pdf reformatted digital access Ecosystems face both local hazards, such as over-exploitation, and global hazards, such as climate change. Since the impact of local hazards attenuates with distance from humans, local extinction risk should decrease with remoteness, making faraway areas safe havens for biodiversity. However, isolation and reduced anthropogenic disturbance may increase ecological specialization in remote communities, and hence their vulnerability to secondary effects of diversity loss propagating through networks of interacting species. We show this to be true for reef fish communities across the globe. An increase in fish-coral dependency with the distance of coral reefs from human settlements, paired with the far-reaching impacts of global hazards, increases the risk of fish species loss, counteracting the benefits of remoteness. Hotspots of fish risk from fish-coral dependency are distinct from those caused by direct human impacts, increasing the number of risk hotspots by similar to 30% globally. These findings might apply to other ecosystems on Earth and depict a world where no place, no matter how remote, is safe for biodiversity, calling for a reconsideration of global conservation priorities. specialized MONDE 034 036 021 12 1 7282 [10 ] 2021 https://www.documentation.ird.fr/hor/fdi:010083872 10.1038/s41467-021-27440-z [F B010083872] https://www.documentation.ird.fr/hor/fdi:010083872 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2022-01/010083872.pdf IRD - Base Horizon / Pleins textes 2022-01-12 2025-02-24 fdi:010083872 fre
