Photosynthetic Capabilities And Responses Of Hard Corals To Turbidity Influence And Thermal Stress

It was hypothesized that different species and colonies of corals have different photo-physiological responses to exposure time and elevated temperature. This thesis investigates the effect of 2 hours and 24 hours exposure and elevated seawater temperature on the photo-physiology of hard corals coll...

This thesis investigates the effect of 2 hours and 24 hours exposure and elevated seawater temperature on the photo-physiology of hard corals collected from Pulau Kendi, Penang and Pulau Songsong, Kedah. Pulau Kendi and Pulau Songsong are located at the northern region of Peninsular Malaysia, both are known as highly sedimented areas with low-light condition with photosynthetically active radiation (PAR) values of 24.707 ± 1.329 μmol m-2 s-1and 54.267 ± 1.739 μmol m-2 s-1 respectively (measured at 12pm).
