>Bill Fitt and I are organizing a mini-symposium at the 9ICRS (Bali 23-27
>October) entitled "Global Climate Change and Coral Reefs, 2. Bleaching of
>Reef Corals and Other Symbioses. This mini-symposium addresses a >series
of questions that lie at the heart of one of the most >actively researched
and debated areas of coral reef biology.
Three major >questions lie at the heart of this mini-symposium:
>(1) What do we know about the mechanisms underlying coral bleaching
>(physiology of bleaching)?
>(2) What are the long-term ramifications of a change in the frequency and
>intensity of coral bleaching events (ecological ramifications of
>(3) Is mass coral bleaching a sign of climate change (implications of
climate change for coral >reefs)?
There are also many other potent and interesting questions that are allied
to this theme and which we also hope to deal with during this
>Ideally, we hope to be able to make a few joint statements that may be of
>use in the wider arena of the climate change debate.
>This will be a natural follow-on from mini-symposium E1 (Langdon and
>Kleypas) whom we will >be closely working with.
>IF YOU ARE INTERESTED:
>Please send an abstract to David Hopley (David.Hopley at ultranet.net.au) and
>to either myself (oveh at uq.edu.au) or Bill (fitt at sparrow.ecology.uga.edu).
>When contacting David Hopley, please indicate which mini-symposium (E2) you
>intend to present at. >Instructions for abstract submission can be found on
the conference home >page (http://www.nova.edu/ocean/9icrs/). The deadline
for abstract >submission is 30 APRIL 2000.
Looking forward to a great symposium and Bali conference.>See you

Convenors: * Dr. William Fitt, Univ. of Georgia, USA. Dr. Ove
>Hoegh-Guldberg, Univ. of Queensland, Australia.
>Bleaching of reef corals (loss of algal symbionts or their symbiotic
>capacity) has been linked to global warming and the demise of corals and
>other symbiotic invertebrates on tropical reefs. Following the worst and
>most widespread bleaching in record history in 1998, many coral reefs
>the world's tropical oceans appear to be damaged to the point where
>may take 30-100 years. The symposium feature talks on a wide array of
>associated with bleaching phenomena. It will aim to coordinate and
>discussion across important areas range from the molecular (mechanisms and
>bleaching) to the ecological processes (e.g. organismal impacts and
>community change) involved in bleaching. This symposium will also invite
>discussion on the important question of whether bleaching is a sign of
>global climate change and hence seek the participation of coral reef
>biologists interested in longer term patterns and time frames. Particular
>emphasis will be placed on resolving the question of whether coral
>is a threat to reef systems worldwide and whether coral bleaching is set to
>increase in intensity and frequency in the next century.
