Koalas spend a large part of the day sleeping - while their digestive enzymes get to work.
The koala genome, published today, gives us new and valuable information to aid conservation of this marsupial. It identifies special genes that evolved to adapt the koala to its unique lifestyle.
Wollemi pines once covered prehistoric Australia.
Wollemi pines have survived for hundreds of millions of years. Once covering Australia, they now survive in a few isolated spots – but they're coming back in a big way.
For decades, state and federal governments have shed environmental budgets and staff. Now it's up to volunteers to fill the gap.
Male sage grouse at the Seedskadee National Wildlife Refuge, Wyoming.
The Trump administration is reopening a plan negotiated under President Obama to protect Western sage grouse. This could signal to states not to bother working together to protect other endangered species.
Wild bumble bees provide natural pollination for blueberries in North America.
Honeybees receive a lot of attention, but the first North American bee to be listed as an endangered species is a wild bumble bee. Wild bees are vital pollinators, and some are declining rapidly.
Panamanian golden frogs (
Atelopus zeteki) are listed as critically endangered, and may be extinct in the wild.
Chytrid fungus has caused a global "amphibian apocalypse," killing frogs worldwide. Now some appear to be evolving resistance – but a closely related fungus threatens newts and salamanders.

A US$1.6 billion dollar dam in Sumatra threatens the recently discovered and desperately imperilled Tapanuli Orangutan.
Long-eared Myotis bat (
Myotis septentrionalis), photographed in Arizona.
Scientists often use animals and plants as indicators to assess whether ecosystems are polluted. Tracking bats, which cover wide areas and need clean water, could become a way to find potable water.
A Kemp’s ridley hatchling makes its way to the water on Padre Island, Texas.
During sea turtle nesting season, scientists collect data and assess how turtles are doing. But they know less about how plastic pollution, fishing and warming oceans are affecting turtle numbers.
Whoosa vicious helpful predator? You are! Yes you are!
Dingoes increase cattle yields, mountain lions reduce car crashes and vultures eat organic waste: like them or not, predators help humans.
Rocks being removed to make way for farming.
Across large ares of Australia, rocky outcrops are being obliterated to open up more land for farming. But many of these "bush rocks" are refuges for fragile ecosystems.
The last male Northern white rhino died in February. Two females remain, but extinction seems likely.
We can't save all endangered species, but we could save some. Zoo populations will be the last hope for many threatened species.
The thorny devil, one of Australia’s many remarkable and unique animals.
Most of Australia's plants and animals are found nowhere else on Earth. This remarkable biodiversity requires a bolder, brighter conservation vision.
The rising influence of the gun lobby in Australia may have extended the prospects of duck season continuing for the foreseeable future.
Despite its unpopularity with the public and ongoing reports of endangered and non-game birds being killed - duck shooting season commences this month in Victoria, Tasmania and SA.
Most Australian kangaroo species, such as the bettong, are largely out of sight and out of mind.
A new documentary makes some controversial claims about the health of kangaroo populations. But the real threat is not to Australia's iconic kangaroos -- it's to dozens of other, obscure species.
Flowers above, traps below.
Venus flytrap plants have 'traps' that snap shut on insect prey. But they also rely on insects for pollination. New research suggests how the plant avoids eating its allies.
The CSIRO has provided new estimates of population sizes for White Sharks in Australian waters.
How many shark encounters have there been at your local beach? Explore our interactive map to see 20 years of incidents between humans and sharks in coastal waters around Australia.
Biofluorescence makes researching cryptic species such as this Lizardfish easier and less harmful.

Much of the world's ocean is teeming with 'cryptic' fish species, which are small and hard to spot. But a new technique shines a light on these fish, which may in turn help to keep our seas healthy.

On his bush block in the WA wheatbelt, poet John Kinsella attempts habitat restoration and reflects on the responsibilities of the writer as a witness to species loss.
Utah prairie dog, Bryce Canyon National Park.
Congress is moving to cut back the Endangered Species Act and give more power to states. But a recent study shows that state laws are weaker and states have few resources to protect species at risk.
