Our paper on the die-off of the vermetid gastropod, C. maximum, is available online at Coral Reefs. In this paper, we document the sudden and complete extirpation of C. maximum on Mo’orea. We provide preliminary evidence that the die-off was likely even more widespread that just Mo’orea — our recent (July 2016) surveys show that this snail also incurred a complete die-off on many other (but not all) islands throughout French Polynesia (see earlier posts).
