Mass extinction's cause: 'Sick Earth'
What really caused the largest mass extinction in Earth's history? view more (2006-10-23)
Improved estimates of population extinction risk (Harding and McNamara)
An important application of theoretical ecology is in estimation of species extinction risk. Extinction models guide the selection of management regimes for endangered species. Two vital parameters in these models are the mean population growth rate and its variance. However, empirical data on population growth are rarely perfect, but are... view more... (2003-12-10)
Extinction by asteroid a rarity
In geology as in cancer research, the silver bullet theory always gets the headlines and nearly always turns out to be wrong. view more (2008-10-07)
Ancient volcanic eruptions caused global mass extinction
A previously unknown giant volcanic eruption that led to global mass extinction 260million years ago has been uncovered by scientists at the University of Leeds. view more (2009-05-29)
More than a meteor likely killed dinosaurs 65 million years ago
Growing evidence shows that the dinosaurs and their contemporaries were not wiped out by the famed Chicxulub meteor impact alone, according to a paleontologist who says multiple meteor impacts, massive volcanism in India and climate changes culminated in the end of the Cretaceous Period. view more (2006-10-27)
New blow for dinosaur-killing asteroid theory
The enduringly popular theory that the Chicxulub crater holds the clue to the demise of the dinosaurs, along with some 65 percent of all species 65 million years ago, is challenged in a paper to be published in the Journal of the Geological Society on April 27, 2009. view more (2009-04-27)
New theory for mass extinctions
A new theory on just what causes Earth's worst mass extinctions may help settle the endless scientific dust-up on the matter. view more (2006-10-25)
Picky eating potentially perilous for bats
Working in the Department of Ecology and Organismal Biology, Justin Boyles and Jonathan Storm examined the possibility of a link between dietary specialization and the risk of extinction for bats in Australia, Europe and North America. view more (2007-07-25)
Canada's shores saved animals from devastating climate change
The shorelines of ancient Alberta, British Columbia and the Canadian Arctic were an important refuge for some of the world's earliest animals, most of which were wiped out by a mysterious global extinction event some 252 million years ago. view more (2008-10-01)
Dinosaur Deaths Outsourced to India?
A series of monumental volcanic eruptions in India may have killed the dinosaurs 65 million years ago, not a meteor impact in the Gulf of Mexico. view more (2007-10-31)
Ebb and flow of the sea drives world's big extinction events
If you are curious about Earth's periodic mass extinction events such as the sudden demise of the dinosaurs 65 million years ago, you might consider crashing asteroids and sky-darkening super volcanoes as culprits. view more (2008-06-16)
The Mystery of Mass Extinctions Is No Longer Murky
If you are curious about Earth's periodic mass extinction events such as the sudden demise of the dinosaurs 65 million years ago, you might consider crashing asteroids and sky-darkening super volcanoes as culprits. view more (2008-06-18)
Meteor no longer prime suspect in great extinction
The greatest mass extinction in Earth's history also may have been one of the slowest, according to a study that casts further doubt on the extinction-by-meteor theory. view more (2007-10-25)
No safe ground for life to stand on during world's largest mass extinction
The world's largest mass extinction was probably caused by poisonous volcanic gas, according to research published today. view more (2005-12-02)
Study unravels why certain fishes went extinct 65 million years ago
Large size and a fast bite spelled doom for bony fishes during the last mass extinction 65 million years ago, according to a new study to be published March 31, 2009, in the Proceedings of the National Academy of Sciences. view more (2009-03-27)
Dying frogs sign of a biodiversity crisis
Devastating declines of amphibian species around the world are a sign of a biodiversity disaster larger than just frogs, salamanders and their ilk, according to researchers from the University of California, Berkeley. view more (2008-08-13)
Getting on 'the GABA receptor shuttle' to treat anxiety disorders
There are increasingly precise molecular insights into ways that stress exposure leads to fear and through which fear extinction resolves these fear states. view more (2009-10-22)
Dramatic shift from simple to complex marine ecosystems occurred 250M years ago at mass extinction
The earth experienced its biggest mass extinction about 250 million years ago, an event that wiped out an estimated 95% of marine species and 70% of land species. New research shows that this mass extinction did more than eliminate species: it fundamentally changed the basic ecology of the world's oceans. view more (2006-11-27)
UCSB researcher leads worldwide study on marine fossil diversity
It took a decade of painstaking study, the cooperation of hundreds of researchers, and a database of more than 200,000 fossil records, but John Alroy thinks he's disproved much of the conventional wisdom about the diversity of marine fossils and extinction rates. view more (2008-07-11)
Fossil record supports evidence of impending mass extinction
Global temperatures predicted for the coming centuries may trigger a new 'mass extinction event', where over 50 per cent of animal and plant species would be wiped out, warn scientists at the Universities of York and Leeds. view more (2007-10-24)
