It is worth pointing out that the same parrotfishes remain in surprising abundance even today (see Gene Shinn's comments), even though KLDR has been reduced to little more than a pile of limestone rubble shaped like a reef, with what appears to be well over 90% CTB cover.

See our "Conclusions" at end of paper for more on this.

Subject: Re: [Coral-List] New Paper Announcement

I just scanned the interesting paper suggested by Bill Alevizon. I will go through it more carefully later on, but one thing struck me as interesting relative to recent conversations on this listserve. As I recollect the discussion about the recent GCRMN report, some argued that it all about "saving the parrotfish" while others characterize it as a more measured document that that someone other than the authors have translated it into a "save the parrotfish" campaign.

I won't weigh in on this distinctionas I haven't had time to digest the report and don't want to mis-characterize it.  I note that in  the Alevison paper, coral cover at Grecian Rocks dropped from 57.2% in 1974 to 14.3%, while macroalgae rose from 1.7% to 15.6 percent and CTB (apparently an acronym from another paper - apparently some combination of corallines, turf and bare substrate) increased from 38.3% to 68.8%. However one wants to parse these data, they pretty much follow the trends we see in most of the journals.... corals down; dead stuff and algae up. However, in their table 2, the abundance of parrotfish has remained constant. While arguably there are no urchin data..... and "size does matter" in parrotfish grazing, this would seem to point out that "saving reefs" may not be as simple as "saving parrotfish".
