There’s not much left to show megafauna were hunted, but that doesn’t prove they weren’t. Peter Murray

Hunting or climate change? Megafauna extinction debate narrows

What is the oldest debate in Australian science? Probably, the argument over what caused extinction of our Pleistocene megafauna – the diprotodons, giant kangaroos, marsupial tapirs, über-echidnas and…

Really Laos, you shouldn’t have: giving elephants to Japan is a bad idea

Silent declines: recognising unlisted ‘endangered’ species

If an entire forest falls and its occupants approach extinction, does anybody hear it? Since for the vast majority of species, the answer is most likely no, we decided to be proactive and recently published…
When you buy imported products, are you buying dead endangered species as well? Mark Hudson

Globalisation’s dark side: how shoppers consume threatened species

The tide of globalisation drives development, providing jobs and much needed dollars. But development and trade consumes local biodiversity, much of it in the iconic biodiversity hotspots of tropical countries…

Is another mass extinction event on the way?

Why have mass extinctions of species occurred since the late Proterozoic (from 580 million years ago) and repeatedly through the Phanerozoic? Integral to these extinctions were abrupt changes in the physical…
