Extinctions of Australian mammals have long been blamed on foxes and cats – but where’s the evidence?

Dozens of Australian mammal species have declined and gone extinct since European colonisation – and introduced predators are often blamed. But evidence is lacking.

Horses, camels and deer get a bad rap for razing plants – but our new research shows they’re no worse than native animals

Introduced water buffalo and camels trash native plants – don’t they? Our research shows megafauna herbivores have the same impact wherever they are.

Understanding how animals think, learn and interact with one another can inform the science of ecology, as predator and prey shape their world.

Feral desert donkeys are digging wells, giving water to parched wildlife

Incredibly, once the wells dried up some became nurseries for the germination and establishment of wetland trees.

Australia is home to many new species, including wild camels found nowhere else on Earth.

Species counts drive conservation science and policy, yet a major component of biodiversity is excluded from the data: non-native species.

From feral camels to ‘cocaine hippos’, large animals are rewilding the world

Much of the Earth’s megafauna are now found outside their native ranges. Thanks to introduced populations, megafauna richness on each continent is higher today than during the past ~10,000 years.
