Some threatened species hit hard by the bushfires this summer have populations in and around urban areas, which are now crucial refuges. Here are some tips to help improve their odds of survival.
The current state of our climate shouldn't be dismissed as a 'new normal'. The hard truth is many of our ecosystems will not recover from the damage.
There are 60,000 abandoned mines in Australia. How do we restore them so that animals return? A researcher's epic fieldwork project in WA's Mid West could help provide the answers.
Humans are probably causing what ice ages and asteroids caused before them.
The Earth has experienced five periods of mass extinction. Scientists can't quite be certain yet, but they're fairly sure we're now well into the sixth.

Aside from their intrinsic value, common bird species might be one of the only ways we connect with nature in our everyday lives. But these opportunities are under threat.
Koalas are among the threatened native species worst affected by habitat loss.
A staggering 7.7 million hectares of critical habitat has been destroyed since environment laws were enacted - and 93% was not referred to the federal government for assessment.
Doug Ford’s government is weakening environmental laws in Ontario — leaving wildlife and environments with no protections.
Doug Ford's government is undercutting the environment by giving business and development the upper hand.

Just one out of a possible 775 development approvals was refused on the basis that it would harm the southern black-throated finch, despite this endangered species being protected by federal law.
Woolly monkeys are hard to miss in Colombia’s jungles. Now, they face extinction.
Colombian researchers hope to revive an endangered species by rehabilitating monkeys confiscated from smugglers. The captive animals' struggles show that survival is not guaranteed.
A kangaroo finds refuge in a small patch of vegetation surrounded by a new housing estate.
Expanding cities and farmland have created many small, often isolated patches of vegetation. Long seen as having limited ecological value, a new study shows these are vital for endangered species.
The burrowing owl was once a common sight on the prairies. Now Saskatchewan and Alberta have fewer than 1,000 breeding pairs.
Carving up ecosystems or opening them to development puts the survival of species at risk.
Like many migratory songbirds, tree swallows are experiencing population declines in parts of their breeding range.
Effective conservation of migratory songbirds requires an understanding of how populations are connected between seasons. The challenge is being able to track individuals throughout the entire year.
Eyes in the sky: drone footage is becoming a vital tool for monitoring ecosystems.

Ecology is in the midst of a technological revolution. From tiny sensors that can be fitted to animals, to swarms of remotely-piloted drones, researchers have a host of new ways to study the natural world.
Masses of snow geese take to the sky at Bosque del Apache National Wildlife Refuge in New Mexico.
The Interior Department is narrowing protection for migratory birds to cover only deliberate harm such as hunting, but not threats like development or pollution that kill millions of birds yearly.
Sudden droughts are bad news for political stability worldwide.
A new international report makes for bleak reading on the state of the world's soils. It predicts that land degradation will displace up to 700 million people worldwide by mid-century.
