Cultures of coral symbionts exposed to thermal stress show systematic changes in the distribution of membrane and energy storage lipids, consistent with known thermal tolerance of different clades (Kneeland, Ph.D. thesis, 2011; Kneeland et al., 2013). Similar results are seen in cultured coral fragments exposed to stress from elevated temperatures as well as bacterial pathogens (Cervino et al., 2008). An on-going investigation of lipid changes in cultured coral symbionts is yielding insights into the cellular mechanisms of symbiont stress, including occurrence of apoptosis during coral thermal bleaching (Becker et al., in prep).
