Summer bleaching of corals has been prevalent in the coastal waters of India in recent years before the onset of monsoon. Repeated bleaching of shallow water corals has changed the benthic dynamics of reef ecosystems. In the present study two locations, Wandoor and Burmanullah in South Andaman, were identified where such changes have occurred. After 3 years of study, the shift from coral domination to macroalgae and sponge is evident. In Wandoor, fleshy macroalgae (28.80%) have become a dominated benthic substrate and in Burmanullah, sponges (19.50%) have taken over much of reef space. Observation of multispecies domination of macroalgae in Wandoor and single species domination of sponges in Burmanullah has been established through this study of shallow reefs.

近年来，在季风爆发之前的印度沿海水域，夏季珊瑚的漂白非常普遍。浅水珊瑚的反复漂白改变了珊瑚礁生态系统的底栖动力。在本研究中，确定了安达曼南部的两个地方Wandoor和Burmanullah。经过3年的研究，从珊瑚统治到大型藻类和海绵的转变是显而易见的。在旺道（Wandoor），多肉的大型藻类（28.80％）已成为主要的底栖基质，而在布尔曼努拉（Burmanullah），海绵（19.50％）占据了礁石的大部分空间。通过对浅礁的研究，已经确定了在万德河中大型藻类的多物种控制和在布尔曼努拉的海绵中单一物种的控制。
