Dear Coral-listers,
I work for the Seychelles Islands Foundation, my colleagues and I are investigating the barriers to effective management of island ecosystems, from a practitioner's perspective. Could you help us out by completing this online survey?
https://oxford.onlinesurveys.ac.uk/barriers-to-effective-island-ecosystem-management
Are you working, or have you worked in conservation and management of island ecosystems in the past three years?
rangers/wardens/fieldworkers/science-officers/managers/ceos/academics/consultants ?
If so, we need your help to better understand the day-to-day challenges you are facing in your goal to meet management objectives and achieve effective conservation of island ecosystems.
We would be super grateful if you could share with your contacts and networks so we can hear from those at the frontline of island ecosystem management.
Very best wishes to you all,
April J Burt

Thanks David:
Going back to a thread from a couple years back, this is the reason that
extensive citing of the literature (and not just the most recent and "hot"
articles) is so important.

Doug - Their interpretation for the Maldives is that the carbonate sequence
was all produced in shallow water, over the subsiding volcanic plateau.
Deposition rates varied across the plateau, some areas remaining shallow
and other areas drowning. The areas that remained shallow developed into
flat-topped sea-level banks during a long period of relatively stable sea
level just over 3 million years ago. Atoll morphology subsequently
developed over the flat-topped banks, and is therefore independent of the
deeply buried volcanic substrate. I think it is a good model, with some
solid supporting evidence from the Maldives. But the article would be so
much better if it exercised more restraint and balance; e.g. by conceding
that there may be multiple paths to atoll morphology, by acknowledging that
Darwin had already suggested some atolls develop from submerged banks, and
by citing previous work apparently contradictory to their conclusions.
By the way, Darwin's tentative explanation of the Maldives was to slowly
submerge a large elongate island surrounded by a barrier reef, like New
Caledonia. The reef "*...after repeated subsidences, would become during
its upward growth separated into distinct portions; and these portions
would tend to assume an atoll-like structure, from the coral growing with
vigour round their entire circumferences, when freely exposed to an open
sea." *Referring to these sub-atolls, he later says* "...these again,
during long periods of subsidence, would sometimes become dissevered into
smaller atolls.*" I know it is just logic, but sure seems like magic!
