Tomorrow's endangered species: Act now to protect species not yet under threat
Conservationists should be acting now to protect mammals such as North American reindeer which risk extinction in the future as the human population grows, according to research published today.   view more (2006-03-07)

Earliest embryos ever discovered provide clues to dinosaur evolution, parenting
The embryos of a long-necked, herbivorous dinosaur are the earliest ever recorded for any terrestrial vertebrate and point to how primitive dinosaurs evolved into the largest animals ever to walk on earth.   view more (2005-07-29)

Duck-billed dinosaurs outgrew predators to survive
With long limbs and a soft body, the duck-billed hadrosaur had few defenses against predators such as tyrannosaurs. But new research on the bones of this plant-eating dinosaur suggests that it had at least one advantage: It grew to adulthood much faster than its predators, giving it superiority in... view more (2008-08-06)

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)

Meat-eating dinosaur from Argentina had bird-like breathing system
The remains of a 30-foot-long predatory dinosaur discovered along the banks of Argentina's Rio Colorado is helping to unravel how birds evolved their unusual breathing system.   view more (2008-09-30)

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)

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)

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)

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)

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)

Birds going extinct faster due to human activities
Human activities have caused some 500 bird species worldwide to go extinct over the past five millennia, and 21st-century extinction rates likely will accelerate to approximately 10 additional species per year unless societies take action to reverse the trend, according to a new report.   view more (2006-07-06)

Reproductive speed protects large animals from being hunted to extinction
The slower their reproductive cycle, the higher the risk of extinction for large grazing animals such as deer and antelope that are hunted by humans.   view more (2007-05-16)

NOAA proposes federal regulations to protect black abalone
NOAA Fisheries Service published with the Federal Register today a proposed rule to list black abalone, a marine mollusk coveted by fishermen and gourmets alike, as endangered under the Endangered Species Act (ESA).   view more (2008-01-14)

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)

New evidence on the role of climate in Neanderthal extinction
The mystery of what killed the Neanderthals has moved a step closer to resolution after an international study led by the University of Leeds has ruled out one of the competing theories - catastrophic climate change - as the most likely cause.   view more (2007-09-13)

Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today.   view more (2007-03-29)

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)

Climate change isolates Rocky Mountain butterflies
Expanding forests in the Canadian Rocky Mountains are slowly isolating groups of alpine butterflies from each other, which may lead to the extinction of the colourful insects in some areas, says a new study from the University of Alberta.   view more (2007-08-14)

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)

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... view more (2006-11-27)

Brain structure associated with fear inhibition also may influence personality

Pre-Amir Dinosaur Is A Newcomer From America
Remains of a dinosaur new to Russia have been found in the town of Blagoveshchensk and described by a Russian paleontologist. Previously, remains of the nearest relations of this pangolin - Kerberosaur - were found only in North America.   view more (2004-10-22)

Luck gave dinosaurs their edge
T. rex and Triceratops: In the popular imagination, dinosaurs are extraordinary reptiles that ruled the world for over 160 million years. But Steve Brusatte, a doctoral student at Columbia University who is an affiliate of the American Museum of Natural History, and colleagues are challenging this... view more (2008-09-12)
