Abstract The inter-specific resilience among mangrove species to sea level rise (SLR) is a key to design conservation strategies for this economically important ecosystem that is among the most vulnerable to SLR. Tectonic processes can cause sudden increases or drops in sea level due to subsidence or uplift of the land surface, which can also provide insights for the mangrove community responses to rapid sea level change. This study aimed to investigate the responses of mangrove species to rapid SLR caused by land subsidence of 1.1 m during the 2004 Sumatra-Andaman earthquake at Car Nicobar Island. The Rhizophora spp. showed remarkable resilience to this rapid SLR, while the landward mangrove vegetation comprising Bruguiera spp., Lumnitzera spp., Sonneratia spp. etc., were unable to survive. Also, Rhizophora spp. establishment in the previous landward mangrove zones was more rapid than the landward mangrove species establishment in the previous terrestrial zones. The observed resilience of Rhizophora spp. may be due to the local specific geological legacy and species-specific ecological processes. However, further studies focusing on microcosm experiments to understand the Rhizophora spp. resilience to rapid SLR at the study site is required to strengthen these observations.

红树林社区对沉降造成印度尼科巴岛海平面变化的反应

摘要 红树林物种对海平面上升 (SLR) 的种间复原力是为这个具有重要经济意义的生态系统设计保护策略的关键，该生态系统是最容易受到 SLR 影响的生态系统。由于地表下沉或抬升，构造过程可能导致海平面突然升高或下降，这也可以为红树林群落对海平面快速变化的反应提供见解。本研究旨在调查红树林物种对 2004 年 Car Nicobar 岛苏门答腊-安达曼地震期间 1.1 m 的地面沉降引起的快速 SLR 的响应。Rhizophora spp。对这种快速 SLR 表现出显着的恢复力，而陆上红树林植被包括 Bruguiera spp.、Lumnitzera spp.、Sonneratia spp. 等，无法生存。此外，Rhizophora spp。在以前的陆地红树林区的建立速度比以前的陆地区的陆地红树林物种建立速度更快。观察到的 Rhizophora spp 的恢复力。可能是由于当地特定的地质遗产和特定物种的生态过程。然而，进一步的研究侧重于微观实验以了解 Rhizophora spp。为了加强这些观察，需要研究地点对快速 SLR 的适应能力。
