Insect predation sheds light on food web recovery after the dinosaur extinction
The recovery of biodiversity after the end-Cretaceous mass extinction was much more chaotic than previously thought, according to paleontologists. view more (2006-08-25)
Madagascar`s lost wilderness @ the London `Catastrophes` conference
In the last 2000 years Madagascar has lost its entire endemic megafauna. This includes giant lemurs, pygmy hippos, elephant birds, and giant tortoises. This loss is the planet`s most recent prehistoric extinction event affecting a region with continental-scale diversity. view more (2002-08-17)
Scientists warn that species extinction could reduce productivity of plants on Earth by half
An international team of scientists has published a new analysis showing that as plant species around the world go extinct, natural habitats become less productive and contain fewer total plants -- a situation that could ultimately compromise important benefits that humans get from nature. view more (2007-11-06)
New evidence implicates humans in prehistoric animal extinctions
Research led by UK and Australian scientists sheds new light on the role that our ancestors played in the extinction of Australia's prehistoric animals. The study, published this week in the journal Proceedings of the National Academy of Sciences of the USA, provides the first evidence that Tasmania's giant kangaroos and marsupial 'rhinos' and... view more...

Mammals that hibernate or burrow less likely to go extinct
The best way to survive the ill-effects of climate change and pollution may be to simply sleep through it. view more (2009-01-29)
A new day dawned fast
In 1980, Luis Alvarez and his collaborators stunned the world with their discovery that an asteroid impact 65 million years ago probably killed off the dinosaurs and much of the the world's living organisms. But ever since, there has been an ongoing debate about how long it took for life to return to the devastated planet and for ecosystems to... view more... (2009-10-05)
Recovering from a mass extinction
The full recovery of ecological systems, following the most devastating extinction event of all time, took at least 30 million years, according to new research from the University of Bristol. view more (2008-01-21)
Size matters: Preventing large mammal extinction
Saving large mammals such as elephants and rhino from extinction could be made more effective by focusing efforts on individual species as well as their habitats. view more (2005-07-25)
Extinction
Two teams of British scientists have produced the best evidence yet that our planet is experiencing a mass extinction. Two separate papers, published in Science 19 March and funded largely by the Natural Environment Research Council (NERC) highlight the serious concerns that have been growing among the world's scientists for over ten years. John... view more... (2004-03-18)
MIT IDs mechanism behind fear
Researchers from MIT's Picower Institute for Learning and Memory have uncovered a molecular mechanism that governs the formation of fears stemming from traumatic events. view more (2007-07-16)
Researchers Find That Well-Timed Timeout Is More Effective In Wiping Out Memory Response to Fear Stimulus
Banishing a fear-inducing memory might be a matter of the right timing, according to new research. view more (2009-04-03)
First global bird map provides new clues to future extinctions
The first global survey of bird diversity could play a key role in identifying species most vulnerable to extinction, researchers report today in the journal PLoS Biology. view more (2006-06-20)
Seismic images show dinosaur-killing meteor made bigger splash
The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago. view more (2008-01-24)
Butterfly fish 'may face extinction'
A beautiful black, white and yellow butterflyfish, much admired by eco-tourists, divers and aquarium keepers alike, may be at risk of extinction, scientists have warned. view more (2008-02-25)
New theory on largest known mass extinction in the history of the earth
Did volatile halogenated gases from giant salt lakes at the end of the Permian Age lead to a mass extinction of species? view more (2009-03-31)
Princeton geoscientist offers new evidence that meteorite did not wipe out dinosaurs
A Princeton University geoscientist who has stirred controversy with her studies challenging a popular theory that an asteroid wiped out the dinosaurs has compiled powerful new evidence asserting her position. view more (2009-05-05)
Yale biologists 'trick' viruses into extinction
While human changes to the environment cause conservation biologists to worry about species extinction, Yale biologists are reversing the logic by trying to trap viruses in habitats that force their extinction, according to a report in Ecology Letters. view more (2007-02-13)
No need to thank dinosaur-killing asteroid for mammalian success
It is a natural history tale that every third grader knows: The dinosaurs ruled the Earth for hundreds of millions of years, until an asteroid struck the Yucatan Peninsula and triggered a mass extinction that allowed the ancestors of today's mammals to thrive. view more (2007-03-29)
Extinction most likely for rare trees in the Amazon rainforest
Common tree species in the Amazon will survive even grim scenarios of deforestation and road-building, but rare trees could suffer extinction rates of up to 50 percent, predict Smithsonian scientists and colleagues in the Aug. 12 issue of the journal Proceedings of the National Academy of Science. view more (2008-08-14)
Ancient DNA traces the woolly mammoth's disappearance
Some ancient-DNA evidence has offered new clues to a very cold case: the disappearance of the last woolly mammoths, one of the most iconic of all Ice Age giants, according to a June 7th report published online in Current Biology, a publication of Cell Press. view more (2007-06-08)
