Mathematics predicts a sixth mass extinction

2017-09-20 06:00:00| LifeSciencesWorld

[NEWS] In the past 540 million years, the Earth has endured five mass extinction events, each involving processes that upended the normal cycling of carbon through the atmosphere and oceans. These globally fatal perturbations in carbon each unfolded over thousands to millions of years, and are coincident with the widespread extermination of marine species around the world. The question for many scientists is whether the carbon cycle is now experiencing a significant jolt that could …

When it comes to the threat of extinction, size matters

2017-09-18 06:00:00| LifeSciencesWorld

[NEWS] CORVALLIS, Ore. — Animals in the Goldilocks zone — neither too big, nor too small, but just the right size — face a lower risk of extinction than do those on both ends of the scale, according to an extensive global analysis. Reporting today in the Proceedings of the National Academy of Sciences, researchers who determined body masses for thousands of vertebrate animal species showed that the largest and smallest species face a greater risk of extinction than do m…

Geologist offers new clues to cause of world's greatest extinction

2017-07-31 06:00:00| LifeSciencesWorld

[NEWS] A study by a researcher in the Syracuse University College of Arts and Sciences offers new clues to what may have triggered the world's most catastrophic extinction, nearly 252 million years ago. James Muirhead, a research associate in the Department of Earth Sciences, is the co-author of an article in Nature Communications (Macmillan Publishers Limited, 2017) titled “Initial Pulse of Siberian Traps Sills as the Trigger of the End-Permian Mass Extinction.&quo…

Conserve intact forest landscapes to maximize biodiversity, reduce extinction risk

2017-07-19 06:00:00| LifeSciencesWorld

[NEWS] CORVALLIS, Ore. — A new global analysis of forest habitat loss and wildlife extinction risk published July 19 in the journal Nature shows that species most at risk live in areas just beginning to see the impacts of human activities such as hunting, mining, logging and ranching. The researchers argue that these intact areas deserve higher priority for limited conservation dollars than areas already impacted heavily by human activity even though species are also threat…
