Identifying priority areas for conservation to promote connectivity and mitigate the impacts of anthropogenic disturbance

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract As nations seek to expand protected area (PA) networks to cover 30% of land and seas by 2030 (30×30), there is an urgent need for systematic conservation planning and spatial prioritization that considers the broad range of ecological and socioeconomic factors influencing the persistence of biodiversity.

Vulnerability of tropical fish communities across depth in the central Indian Ocean

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.
