The increase in climate-related extreme events and ecosystem degradation demands consistent and sustainable climate mitigation efforts. Seagrass playing a key role in nature-based carbon sequestration mitigation strategy. Here, we investigated the role of coral reef connectivity in blue carbon dynamics with seagrass meadows with coral reef connectivity (SC areas) and without coral reef connectivity (SG areas) in Palk Bay, India. The high sediment organic carbon was recorded in SC areas (90.26 ± 25.68 Mg org.C/ha) and lower in SG areas (66.96 ± 12.6 Mg org.C/ha). The maximum above-ground biomass (AGB) was recorded in Syringodium isoetifolium (35.43 ± 8.50) in SC areas and the minimum in Halophila ovalis (7.59 ± 0.90) in SG areas, with a similar trend observed in below-ground biomass (BGB). Our findings highlight the importance of coral reefs in enhancing the blue carbon potential of seagrass ecosystems and underscore the need for integrated conservation and restoration strategies for coral reefs and seagrasses.

印度帕尔克湾海草生态系统有机碳储量改善中珊瑚礁连通性的评估


与气候相关的极端事件和生态系统退化的增加需要持续和可持续的气候缓解努力。海草在基于自然的碳封存缓解策略中发挥着关键作用。在这里，我们研究了印度帕尔克湾具有珊瑚礁连通性（SC 区域）和不具有珊瑚礁连通性（SG 区域）的海草草甸的珊瑚礁连通性在蓝碳动态中的作用。 SC 地区沉积物有机碳含量较高（90.26 ± 25.68 Mg org.C/ha），SG 地区沉积物有机碳含量较低（66.96 ± 12.6 Mg org.C/ha）。 SC 地区地上生物量 (AGB) 最大的是 Syringodium isoetifolium (35.43 ± 8.50)，SG 地区 Halophila ovalis 最小 (7.59 ± 0.90)，地下生物量 (BGB) 也有类似的趋势。我们的研究结果强调了珊瑚礁在增强海草生态系统蓝碳潜力方面的重要性，并强调需要对珊瑚礁和海草采取综合保护和恢复战略。
