Losing Australia’s diggers is hurting our ecosystems

Despite once being described as common, mammals have been lost across the Australian landscape over the last 200 years. The impact has been particularly severe on Australia’s digging mammals, including…
Megafauna such as Glyptodon were muck-spreaders. Pavel Riha

Megafauna extinction affects ecosystems 12,000 years later

If Earth were like a human body, large animals might be its arteries, moving nutrients from where they’re abundant to where they’re needed. Currently the planet has large regions where life is limited…

What can history tell us about species coping with climate change?

In work we published in Science today we look at two conflicting ideas on whether species can adapt to climate change. Are our ideas about extinction too catastrophic, or do we actually need to do more…

Produce mammoth stem cells, says creator of Dolly the sheep

It is unlikely that a mammoth could be cloned in the way we created Dolly the sheep, as has been proposed following the discovery of mammoth bones in northern Siberia. However, the idea prompts us to consider…
The decline of this Indian vulture species has costed the economy $30 billion. Bharat Balasubramanian

Neither the charismatic nor the iconic: rethinking conservation

The rate of extinction of species today is many thousand times the natural rate. There are even examples that such loss can have serious impact on humans. So a critical question is: what is the role species…
Extinctions: happening since before we were around, but happening a lot more now. Andrew Milligan/PA

Our role in extinctions cannot be denied

The State of Nature report published this month showed that of more than 3,100 British species surveyed, 60% are in decline, and one in 10 of those species on the Red List are under threat of extinction…
Lonesome no more. George died on 24 June 2012. A.Davey

Stop singletons becoming endlings to save ecosystems

There can be few words as poignant as “endling”, the name given to the last surviving individual of a species. The picture (below) of Benjamin, the last Tasmanian tiger or thylacine, is heartbreaking…
The Christmas Island Shrew has been recorded four times since its discovery. Max Orchard

Australian endangered species: Christmas Island Shrew

It may be that there are no more shrews in Australia. There was only ever one representative, edging into the Australian political estate on the remote Christmas Island, closer to Java than any other part…
Giant creatures such as the marsupial ‘lion’ (Thylacoleo carnifex) didn’t die out from hunting. Peter Schouten

Climate change wiped out Australia’s megafauna

Throughout the Ice Age that characterised our planet for much of the last two million years or so mainland Australia, Tasmania and New Guinea formed a single landmass — Sahul. It was a strange and often…

Extinction: just how bad is it and why should we care?

“Dad, the world is missing amazing animals. I wish extinction wasn’t forever”. Despite my wife and I working as biologists, our five-year-old son came to make this statement independently. He is highlighting…

Another link between CO2 and mass extinctions of species

It’s long been known that massive increases in emission of CO2 from volcanoes, associated with the opening of the Atlantic Ocean in the end-Triassic Period, set off a shift in state of the climate which…
Dead as a … extinct species should stay extinct, and we should focus on saving the ones still living. Jebulon

De‑extinction is about as sensible as de‑death

On Friday, March 15 in Washington DC, National Geographic and TEDx are hosting a day-long conference on species-revival science and ethics. In other words, they will be debating whether we can, and should…

History mystery solved: the origins of the Falkland Islands wolf

A long-standing natural history mystery has been solved, as my colleagues and I explain today in the journal Nature Communications. The Falkland Islands wolf, or warrah, may have been the world’s loneliest…
