Extinction domino effect linked to climate change

Environmental changes increase the risk of an ‘extinction domino effect’ that could annihilate all life on Earth, according to new research. Researchers, including CABAH Chief Investigator Professor Corey Bradshaw, simulated 2,000 ‘virtual Earths’ linking animal and plant species. Using sophisticated modelling, they subjected the virtual Earths to catastrophic environmental changes, including runaway […]

Using drones to study extensive Aboriginal stone-walled fishtraps in the Gulf of Carpentaria

CABAH researchers have used high-resolution close-range Unmanned Aerial Vehicle (UAV) photogrammetry and a suite of spatial information analytical techniques to investigate Kaiadilt Aboriginal stone-walled intertidal fishtraps on Sweers Island in the southern Gulf of Carpentaria, Australia. Stone-walled intertidal fishtraps were built to control the movements of marine animals. They are […]

How Antarctic ice melt can be a tipping point for the whole planet’s climate

Melting of Antarctica’s ice can trigger rapid warming on the other side of the planet, according to our new research which details how just such an abrupt climate event happened 30,000 years ago, in which the North Atlantic region warmed dramatically. This idea of “tipping points” in Earth’s system has had something […]

Rewriting History: Australia’s oldest known campsite

Archaeologists, working together with Mirrar Aboriginal people, are unlocking some extraordinary secrets from Australia’s oldest known campsite. Latest dating techniques have established a new minimum age for arrival of the first Australians at least 65,000 years ago. This suggests Aboriginal people and megafauna co-existed for 20,000 years or more. Perhaps […]
