[Coral-List] Risk of coextinction in coral reefs

Dear coral-listers,

Coextinction in coral reefs is rarely mentioned.
In simple words, coextinction means that as a host species becomes extinct,
so does one or more species of parasites.
Although parasites are generally not considered charismatic animals, they
play a major role in the ecology and evolution of their hosts and are an
indispensable component of ecosystems, including, of course, coral reefs.

I am writing to bring your attention to a recent paper we have published. It
may be of interest to all who are interested in conservation of coral reefs.
Our main result is that if a fish disappears, at least 10 species of
parasites will also disappear. This is the first detailed evaluation of the
coextinction ratio in coral reefs.

This is an open access paper, already classified as “highly accessed” by the
publisher, BioMed Central.
