As ecologists, we’ve seen first-hand how Australia’s nature laws have permitted environmental degradation and destruction to the point of extinction.
Humanity is destroying Earth’s ability to support complex life. But coming to grips with the magnitude of the problem is hard, even for experts.
Not all frogs ‘ribbit’ — some sound like a motorbike changing gears or a tennis ball being hit. This summer, keep your eyes and ears out for these Aussie frogs.
Historical photographs of bison extermination are a window into a history of relationships between humans, bison and the environment.
Evolution towards flightlessness has been much more common through history than scientists once thought.
Driven by a desire to eliminate pain, some people have shockingly advocated taking the rest of nature with us.
For 200 years, a small number of countries have exploited the marine wildlife of Antarctica, often with devastating impact on their populations.
Paleontologists have discovered fossil remains belonging to an enormous ‘toothed’ bird that lived for a period of about 60 million years after dinosaurs.
By unlocking the full potential of rhino ovaries, we hope to produce enough eggs to revive the northern white rhino in the wild.
Several theories have suggested either humans, climate change or both drove megafauna extinctions in Southeast Asia. Our newest work suggests otherwise.
The world missed all 20 targets for stemming the tide of biodiversity loss. But there has been some progress over the last decade.
Microfossils offer up an array of information to scientists, like the time periods in which they lived and how environments have changed.
A conservation scientist interviewed on the programme says Sir David tells it like it is.
Museums around the world have been grappling with the issue of diorama removal.
The “Tasmanian tiger” was hunted to extinction based on its perceived size as a predator big enough to take sheep. But it seems this was just a tall tale, and the thylacine weighed just 16.7kg.
Twenty of these freshwater fish species have a 50% or greater probability of extinction within the next 20 years.
Recent reports of dramatic declines in insect populations have sparked concern about an ‘insect apocalypse.’ But a new analysis of data from sites across North America suggests the case isn’t proven.
When the dinosaurs went extinct, some species took over the world. Adaptability, not survivability, explains why.
The teeth and limb bones we studied help to understand the role and lifestyle of these species in extinct ecosystems.
