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.
Rhino resurrection is tempting, but if humans cannot save a species in nature, what future for animals that we manufacture?
The last Carolina parakeet died in a zoo a century ago. A scientist tries to unravel some of this bird's lasting mysteries.
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.
A drying climate caused a mass extinction among plants, but paved the way for the ancestors of modern reptiles, mammals, and birds.
Australian government environmental funding has decreased by a third since 2013. At the same time, Australia is experiencing massive species loss as funding for the sector dries up.
The new Tasmanian tiger genome reveals some fascinating facts about this extinct marsupial, including why they were so similar to dogs, and how they were growing more vulnerable to genetic disease.
Computer models have produced some very worrying results.
The failed attempt to reinstate land clearing regulations in Queensland has prompted 'panic clearing', pushing Australia into the global top-ten deforesters.
