From the reappearance of giant bees to sightings of clouded leopards – can we ever be certain that a species has died out?
It's often said you need to look to the past to learn about the future, and that's what the fossil record can tell about how the Tasmanian Devil survived in the past on mainland Australia.
Mathematic models are becoming more sophisticated and now they could actually predict how likely a species is to die out.
A recent report warned that insects 'could vanish by the end of the century'. Here's why that would cause a collapse of nature.
Ecosystems can collapse suddenly and totally. Frozen zoos are trying to create archives of genetic material to prevent total extinctions.
There are over 100 species of wild coffee, but only a few supply the world's morning caffeine kick. Sadly, climate change and disease could be about to change that.
Climate change threatens to cause mass extinctions – but how, exactly? New research suggests male fertility may be the weakest link.
The loss of the Siberian unicorn shows just how vulnerable some animals can be to environmental change that can impact on their food supply.
Carving up ecosystems or opening them to development puts the survival of species at risk.
Lee's research identified the cause of mysterious and devastating mass frog extinctions that spread across the world starting in the 1970s: it was a skin fungus.
It's quite hard to tell when a sea creature is extinct – there's always hope it will turn up somewhere.
Death is inevitable for individuals and also for species. With help from the fossil record, paleontologists are piecing together what might make one creature more vulnerable than another.
How can there be boom in new species discoveries while others are dying out at unprecedented rates?
A new analysis explores what making space for nature means for our global food production systems.
We know of about 900 valid dinosaur species that existed. 'Valid' means scientists know the dinosaur from enough of the skeleton bones to feel pretty sure that it differs from other known dinosaurs.
Shaded valleys and other cool habitats could help save threatened plants and animals from extinction.
What drives the emergence and disappearance of species? By modeling the fundamental processes of evolution and ecology on geographical scales, new research spotlights topography and climatic shifts.
The Earth is losing more and more biodiversity every day, and we should all be worried
Scientists have created embryos from the eggs of southern white rhino and sperm from their northern counterparts.
More than 160 thylacine specimens lie in museum collections in the UK. The sight of their bodies is a shocking reminder of loss.
