Those of you who work with corals know that their systematics is 
often a challenge regardless of whether one is working at the level 
of species or higher taxonomic levels.  Hence the following 
mini-symposium for the upcoming Okinawa meetings.

1-1	Coral Taxonomy and Phylogeny: Integrating Molecular and 
Morphological Approaches (Nancy Knowlton, Ann F. Budd, and Hironobu 
At present, most coral scientists depend on classical morphological 
taxonomy to identify the coral species and define higher groups. 
However, recent studies using molecular techniques do not always 
support conventional morphological assignments. Molecular results may 
prompt reinterpretation of morphological characters, and molecular 
results also need to be considered in light of morphological 
characters and the fossil record of corals. Here we propose a 
symposium whose goal is to further the integration of molecular and 
morphological approaches, which is crucial because only morphology is 
available for fossil material. We hope to bring together scientists 
from a diverse array of disciplines (paleontology, systematics, 
reproductive biology, molecular genetics) in order to define areas of 
conflict in data sets and avenues of future collaborations.

We have made a good start on our program (summarized below), but 
would like to persuade a few more of you to participate.  Please let 
us know if you would be interested in doing so, and send in your 
abstract!!  If you want to suggest someone that we should contact 
directly please do so as well.  The more diverse the participants, 
the more we can learn about how to tackle this challenging but 
central problem.

Many many thanks,
Nancy Budd, Nancy Knowlton and Hiro Fukami
