A new study has confirmed that sharks follow established patterns when it comes to body size, and this finding could change ...

Shell-rich rocks trace a mostly upward climb in ocean life, with each mass extinction slashing both diversity and biomass ...

Conservation efforts alone may not be enough to prevent a looming bird extinction crisis. Specific rescue strategies are ...

Fusulines thrived in cold seas but vanished twice when warming from volcanoes rapidly spiked ocean carbon levels.

Stanford study shows ocean biomass has risen over 540 million years, linking biodiversity to long-term ecosystem health.

If we take that figure and assume 100 E/MSY over 500 years — subtracting the 3,850 animals that would be expected to naturally go extinct over 500 years with a 1 E/MSY background extinction rate ...

But because these animals cross national borders and frequently congregate at predictable way stops, they are uniquely vulnerable to human predation, pollution and habitat loss. As a result, one in ...

At least five times, a catastrophe has killed off the vast majority of Earth’s species. As scientists say we’re in a sixth mass extinction, what can we learn from the past?

How the Current Mass Extinction of Animals Threatens ... now that we're living through the sixth massive extinction. The fifth one was 65 million ... at a similar rate. And ...

If so, it may be the fastest one ever with a rate of 1,000 to 10,000 times the baseline extinction rate of one to five species per year. Humans are largely responsible for the striking trend.
