Assessment of the protection of coastal reef-fish habitat across an isolated oceanic archipelago using spatial distribution models
Effective marine protected area (MPA) networks demand precise knowledge of habitat distribution, a challenge in remote archipelagos where comprehensive surveys are often impractical. This study assesses coastal reef-fish habitat protection across the Azores archipelago using species distribution models (SDMs), integrating visual census data with seabed and oceanographic variables. Our random forest approach predicts habitat suitability, revealing that while current MPAs generally align with high-suitability areas, protection remains limited.
Evaluating the effectiveness of marine ecological red lines: an integrated assessment of ecological outcomes and governance performance
Marine Ecological Red Lines (MERLs) represent a significant spatial conservation policy, particularly in China, yet their effectiveness requires rigorous, quantitative evaluation. This study introduces an indicator-based assessment framework, grounded in the PSR model, to evaluate MERL performance by integrating anthropogenic pressures, ecosystem conditions, and management responses. Initial findings from Hainan Province demonstrate reduced pressures and improved ecological conditions within MERLs compared to adjacent areas.
Mapping offshore wind potential and spatial trade-offs for marine planning in Caribbean Small Island Developing States
Offshore wind presents a vital pathway to decarbonization and energy security for Caribbean Small Island Developing States (SIDS). Addressing data fragmentation, this study establishes a reproducible spatial framework to assess wind potential while considering environmental constraints across 12 Caribbean EEZs. Mapping wind speeds and integrating foundation technologies, we identified 10.03% of the maritime domain as ‘Opportunity’ zones, with only 0.36% designated as ‘Trade-off’ areas. For further exploration of marine ecosystems, see our article, "Coral Reefs.
Functional connectivity in China’s coastal MPAs: modeling critical corridors and restoration zones for economic fish under climate change
Climate change is fundamentally reshaping marine ecosystems, disrupting functional connectivity within protected area networks. A recent study utilized ensemble species distribution models to assess these shifts across 193 coastal Marine Protected Areas (MPAs) in China, projecting habitat suitability for eight economically important fish species under various climate scenarios. Results reveal diverging responses among species, highlighting a critical misalignment between static MPA networks and dynamic connectivity needs.
From spatial expansion to institutional coherence: governance pathways of marine protected areas in island blue economies
Island nations face the dual challenge of advancing marine conservation and developing blue economies amidst intensifying climate pressures. This study comparatively examines marine protected area (MPA) governance in Fiji, Palau, and Taiwan, revealing that institutional coherence—horizontal and vertical coordination—is paramount to effectiveness, exceeding the importance of mere spatial extent. Three governance models emerged, highlighting the need for integrated approaches. Findings emphasize sequencing expansion with robust enforcement and adaptive policy cycles, offering transferable insights for climate-resilient ocean development.
