I am a teacher in Indiana and I have been reading the messages on the
coral reef listserve. I want to know what types of algae are within the
coral as (symbionts?). I was told that rice coral releases the algae
during spawning - do corals release their algae at other times too? Do
stressed coral release some of the zooxanthallae ?
I also wanted to know if there is any measure of UV exposure to the
corals that are bleaching? And if the temperature is as important as
the duration of the temperature? ie could coral withstand a rapid
increase in temperature if it were of real;atively short duration better
than prolonged temperature increases - even at lesser temperatures? I
would think that there might be a greater apoxia as a result of the
prolonged increases in temperature.
