I have a question......it may sound stupid..but i
need to know..
Is there any common single parameter that can be
used as indicator of physiological change across
all coral species..say from healthy to
If not is there any combination of parameters...
I ask this becasue , I am having trouble in
coming to terms with say zooxanthellae
abundance.....of course there is change in
zooxanthellae abundance from healthy to bleached
coral..but it is not in the same range in all
corals...to my disappointment..even in the same
so if two people cunduct stress experiments in
two different corner of the earth..there is no
chance that we can say about the physiological
changes in the corals by looking at the
zooxanthellae abundance since healthy
zooxanthellae number for my coral sample may be
stressed zooxanthellae number for the other
persons coral sample....
this does not stop only with zooxanthellae
abundance, say chlorophyll or HSPs or any other
parameter for that matter...
hmm....how do i know about the physiological
condition of a coral sample..if there is so much
variation...and not even a single parameter holds
good to analyse the physiology?
I think these basic problems in coral research
gives us researchers and policy makers and
everyone involved in coral research leverage to
make each of our own point or thoughts hold
