Abstract The increasing atmospheric CO 2 concentration in the last few decades has resulted a decrease oceanic pH. In this study, we assessed natural variability of pH coastal waters off Goa, eastern Arabian Sea. T showed large (7.6–8.1) with low conditions during south‐west monsoon (SWM), and is found to be associated upwelling rather than freshwater runoff. Considering that marine biota inhabiting dynamic Goa are exposed such wide range fluctuations pH, an acidification experiment was carried out. We studied impact on local population sea urchin Stomopneustes variolaris (Lamarck, 1816). Sea urchins were for 210 days three treatments : 7.96, 7.76 7.46. Our results S. at 7.96 not affected, whereas ones 7.46 adverse effects after 120 50% mortality by days. However, even exposure days, organisms survived. Under (pH 7.46), elemental composition spines exhibited deposition excess Sr 2+ as compared Mg ions. conclude although would affected future high waters, present they risk when reside shelf.

Abstract Coral reefs worldwide are at risk due to climate change. bleaching is becoming increasingly common and corals that survive events can suffer from temporary reproductive failure for several years. While water temperature a key driver in causing coral bleaching, other environmental factors involved, such as solar radiation. We investigated the individual combined effects of temperature, photosynthetically active radiation (PAR), ultraviolet (UVR) on spawning patterns physiology Hawaiian mushroom Lobactis scutaria , using long-term experiments aquaria. examined timing, fertilisation success, gamete physiology. Both warmer temperatures filtering UVR altered timing spawning. Warmer caused drop success. higher PAR both negatively affected sperm egg These results concerning L. similar data urgently needed predict future trends species. Nonetheless, thermal stress global change will need be adequately addressed ensure survival reef-building their natural environment throughout next century beyond. Until then, reproduction likely impaired growing number
