Ice Age flora extinction reveals fresh plant biodiversity clues

Sunanda Creagh, The Conversation dan Jan Wisniewski, The Conversation

Ice Ages caused a mass extinction of plants in south-eastern Australia around a million years ago, according to a new study that presents a fresh take on how extinction shapes biodiversity. Scientists…
We’re happy to kill individual creatures in large numbers - what’s stopping us wiping out the biosphere? Darren Harmon

There are roughly 5 million species on earth. Most are insects. Roger Smith

We can name all of Earth’s species, but we may have to hurry

Conservationists should take heart that Australia is finally waking up to the biodiversity crisis in Australia’s north. It is an urgent problem: right now, a diverse assortment of our small mammals – bandicoots…
A high level of coral cover doesn’t always mean a high level of species diversity; and diversity is important. Maria Beger

A lot of coral doesn’t always mean high biodiversity

Zoe Richards, Western Australian Museum

The health and productivity of coral reefs is rapidly declining. Hard corals are the principal builders of coral reef ecosystems; however they are struggling to survive due to pollution, catchment clearing…
