Based on two measures—phylogenetic diversity and phylogenetic species variability—we highlight regions with the largest losses of evolutionary diversity and hence of potential conservation interest.
Notably, the projected loss of evolutionary diversity is relatively low in the most species-rich areas such as the Coral Triangle, while many regions with fewer species stand to lose much larger shares of their diversity.
We also suggest that for complex ecosystems like coral reefs it is important to consider changes in phylogenetic species variability; areas with disproportionate declines in this measure should be of concern even if phylogenetic diversity is not as impacted. These findings underscore the importance of integrating evolutionary history into conservation planning for safeguarding the future diversity of coral reefs. Introduction The ongoing extinction crisis driven by anthropogenic impacts can potentially reach mass extinction levels in the future unless proper conservation measures are taken [ 1 ].
Species richness has traditionally been the primary metric for quantifying biodiversity and setting conservation priorities [ 2 ], but it is increasingly apparent that given the limited resources available for conservation, not every species can be saved.
This realization has prompted efforts to develop strategies for minimizing the loss of evolutionary diversity ED despite species loss [ 3 — 5 ]. Preserving ED is now seen by some as a goal in itself [ 6 — 10 ], and by others as a proxy for preserving functional diversity and ecosystem function [ 11 — 15 ].
A number of different ED metrics are currently available [ 1617 ], each highlighting somewhat different aspects of the evolutionary process, but empirical analyses of how the loss of a given set of species affects different metrics remain scarce [ 18 ]. This hampers our ability to understand the behaviour of these metrics in real-world situations and also impedes the development of guidelines for their use in risk assessment [ 19 ].
Here we explore this issue using two different measures of ED in conjunction with geographical distributions of all living reef-building coral species to predict regional diversity changes resulting from projected species loss according to the International Union for Conservation of Nature IUCN Red List of Threatened Species [ 20 ]. Our goal is to compare the erosion of regional ED due to anthropogenic extinctions using the two measures, and to use the results to identify coral reef ecoregions whose ED may be most at risk in the future.
Coral reefs are among the most threatened ecosystems of the world [ 21 — 25 ]. One-third of all reef corals Scleractinia are facing heightened extinction risk from climate change and other impacts [ 20 ]. The year-old Veron is a veteran "chucker-outtera": He gets his clothes from Vinnies "the best shop in the world"doesn't own a pair of formal shoes and has successfully purged his home of coral specimens, which remind him of work.

Wolter Peeters Shifting his library, on the other hand, could be trickier. Rivendell is stuffed with books, thousands of titles on everything from Giuseppe Verdi to Lawrence of Arabia. But most of his collection concerns marine biology and coral, a topic Veron knows more about than anybody on the planet. Dubbed the "Godfather of Coral", Veron has, over his year career, redefined our understanding of reefs, the way they grow and reproduce, the way they evolve, and now, most poignantly, the way they are dying.
He has identified more than 20 per cent of the world's coral species, and has been likened by David Attenborough to a modern-day Charles Darwin. He provided that baseline to put everything in context.
If ever there was a moment for Australians to listen up and act on what he's learnt, it's now. He has of late become the go-to guy for anyone seeking a frank opinion about coral bleaching on the Great Barrier Reef.

It won't be here in 15 years. The mine's proponent, the Indian multinational conglomerate Adani, projects there will be more than 4. Veron has variously referred to Carmichael as "evil", "beyond logic" and "appallingly stupid". The larger problem is not the mine, as bad as that is.

It's Australia, it's the world; it's our complacency, our distrust of science and, of course, it's our politicians. Former federal environment minister Greg Hunt is "the most stupid man you could ever hope to meet". Tony Abbott is a "moron"; Queensland Premier Annastacia Palaszczuk, who has also backed the mine, "just awful". Prime Minister Malcolm Turnbull, he says, is the worst of the lot. Then he turns around and does nothing. To me, that is truly criminal. Penguin Random House Australia Scientists are, by nature, cautious.
Instead of opinions, they have facts. Instead of randomness and speculation, they have reason and protocol. Veron is largely the opposite. He abhors protocol and is falling over himself with opinions, many of which have found their way into his new book, A Life Underwater.
Equal parts memoir, coral reef primer and requiem to a planet, Veron's book charts a career that could scarcely be imagined today, a love affair with science birthed from childhood wonderment, free-range academia and happy accidents. Born and raised in Sydney's north, Veron was an awkward child: He spent most of his time roaming nearby bushland or poring for hours over rock pools at Long Reef beach. Veron whose real first name is John had a habit of bringing his discoveries into class — sea worms, funnel web spiders — prompting his teacher to dub him Mr Darwin, or Charlie.
He attended Barker College, a private school, where he failed miserably in everything except biology. In his final year, however, he took part in a one-off government experiment to test whether IQ results could predict university performance better than school leaving exams.
To Veron's amazement, he topped them all, and was offered a Commonwealth scholarship to the university of his choosing.
The future of evolutionary diversity in reef corals
Charlie Veron Veron studied herpetology and entomology. He was about to move to Canada to study locusts when Kirsty came upon an advertisement for postdoc work on corals, based at James Cook University in Townsville. Veron knew virtually nothing about corals but, remembering his time at Long Reef, applied for the position. Little did he know, his was the sole application.Coral Reef Centerpiece DIY for Under the Sea/Mermaid Party!
Thus he set two unlikely records: Veron is slight and wiry; he has a deeply guttered face, grey hair and piercing blue eyes. He is mesmerically articulate, given to long, discursive tutorials on everything from the endurance of coral larvae to the carbon cycle.
He can also be petulant — "No one ever listens to me, I'm just a marine scientist" — and prone to the odd, discordant analogy.
