Effects Of Temperature Stress On Symbiodinium Spp. From Selected Scleractinians
Symbiodinium is described as a coccoid yellow-brown endo-symbiont, which inhabits coral tissues and provides photosynthetic products necessary for corals. However, under stressful conditions such as temperature change, the symbiotic relationship between Symbiodinium and corals may collapse and resul...
