[Coral-List] Bleaching "shuffling" is a catastroph

Dear Jason,

I just read your article in BMC Evol Biol, 2012, 12, 217 on genetic basis of thermal tolerance of clade D. Interresting that you suggest that "clades" are like Family or Order. Very important the evidence of the role of thylakoid membrane stability (I will come latter on this point).

BUT you seem ENTHOUSIASTIC with the possibility of corals to "shuffle" to resistant clade D in front of mass bleaching and Climate Change (i.e. the "Adaptative Bleaching Hypothesis"). NO, for me, it is an horror. Clade D is also very less productive (Little et al., 2004, Cantin et al., 2009, LaJeunesse et al., 2009). Even if "coral species" survive, this means we are losing every days the "good" sensitive symbionts at profit of poor resistant ones (as expected from simple logic). As the process goes on for this century(ies), we will lose the pretty productive reefs, and recovery needs 10 millions years, as seen from previous mass extinctions.

Sorry, the future is very gloomy,
