Humans risk causing a mass extinction of large sea creatures on a scale never before seen because of overfishing, scientists warned this week.
For more than 20 million years, the ups and downs of diversity in terrestrial large mammals were determined by primary production, i.e. net production of plant biomass. This pattern changed with the onset of the ice ages. ...
In the Earth's oceans these days, the bigger a species is, the more prone it is to die off. That's unheard of in the long history of mass extinctions, a new study finds.
Extreme global warming caused a severe mass extinction of life on Earth 252 million years ago. It took life up to 9 million years to recover. New study finds clues in the Arctic as to why this recovery took so long.
Scientists have shed light on why life on Earth took millions of years to recover from the greatest mass extinction of all time.
A new study of fossil fishes from Middle Triassic sediments on the shores of Lake Lugano provides new insights into the recovery of biodiversity following the great mass extinction event at the Permo-Triassic boundary 240 ...
A new study of nearly 22,000 fossils finds that ancient plankton communities began changing in important ways as much as 400,000 years before massive die-offs ensued during the first of Earth's five great extinctions.
There have been several mass extinctions in the history of the earth with adverse consequences for the environment. Researchers from the University of Zurich have now uncovered another disaster that took place around 250 ...
Scientists have discovered the cause of a mass extinction of sea-floor marine organisms 800,000 years ago—which also provides insight into how climate change can impact on deep ocean biota.
In 100 years, many of the world's 7,000 languages could be extinct. Hundreds of years of oral storytelling will disappear in the space of a couple of generations.
