Keeping an eye on how scientific information embargoes affect news coverage

PNAS lifts embargo early on study of extinctions, after author’s university jumps the gun

The Proceedings of the National Academy of Sciences (PNAS) lifted an embargo early yesterday, after a university broke it with a press release.

From an email sent to reporters yesterday about an hour before the embargo was scheduled to lift:

PNAS is lifting the embargo on the following manuscript. All other manuscripts are under the scheduled embargo of Monday, Sep. 18, 3 pm US ET.

*   Vulnerability of vertebrates

An analysis of 27,647 vertebrate species finds an association between body size and extinction risk, and indicates that the lightest and heaviest vertebrate species experience the highest risks of extinction, and that the heaviest vertebrates are most at risk of direct killing by humans, whereas the lightest vertebrates are most at risk of habitat degradation, suggesting that anthropogenic activities could reduce the size distribution of the world’s vertebrates.

PNAS tells Embargo Watch:

A press release from the corresponding author’s institution was published ahead of the scheduled embargo. We are investigating the circumstances.

Here’s the release.
