[Coral-List] fish and corals smell reefs

Great articles.... and very innovative. However, at face value the studies
seem to show that coral larvae have a means to identify places where
settlement would be futile. The subtitle "the scent of a healthy
rejuvenate degraded coral reefs*" infers, at least to me, that we might
somehow synthesize the scent of a "healthy reef" to encourage recruitment
as a means to "fix" the reef. In this scenario, wouldn't it be more akin to
telling people "pay no attention to those flames, this is a great
neighborhood to buy real estate in"?
It seems to me that, if a system is "healthy", it will sent off the
appropriate smells on it's own.... and we needn't do anything.
Alternatively, if it isn't, then all we'd be doing is encouraging
settlement in a high risk area.... and we shouldn't do anything? Thus, the
study provides insight into how corals know how to make wise real-estate
decisions, but a management strategy that tries to create such cues to
encourage recruitment on marginal reefs would be unwise.... yes?
