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)

Species Have Come and Gone at Different Rates than Previously Believed
Diversity among the ancestors of such marine creatures as clams, sand dollars and lobsters showed only a modest rise beginning 144 million years ago with no clear trend afterwards, according to an international team of researchers. This contradicts previous work showing dramatic increases beginning... view more (2008-07-07)

Looming tropical disaster needs urgent action
A major review by University of Adelaide researchers shows that the world is losing the battle over tropical habitat loss with potentially disastrous implications for biodiversity and human well-being.   view more (2008-06-25)

Britain's last Neanderthals were more sophisticated than we thought
An archaeological excavation at a site near Pulborough, West Sussex, has thrown remarkable new light on the life of northern Europe's last Neanderthals. It provides a snapshot of a thriving, developing population - rather than communities on the verge of extinction.   view more (2008-06-24)

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)

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)

Woolly-Mammoth Gene Study Changes Extinction Theory
A large genetic study of the extinct woolly mammoth has revealed that the species was not one large homogenous group, as scientists previously had assumed, and that it did not have much genetic diversity.   view more (2008-06-12)

New study reveals large scale conservation essential
Scientists were surprised with findings of a recent study that reveals many animal species believed to persist in small contained areas actually need broad, landscape level conservation to survive.   view more (2008-06-10)

Engineering researcher seeks answers to asteroid deflection
An Asteroid Deflection Research Center (ADRC) has been established on the Iowa State campus to bring researchers from around the world to develop asteroid deflection technologies. The center was signed into effect in April by the Office of the Executive Vice President and Provost.   view more (2008-05-28)

A missing link settles debate over the origin of frogs and salamanders
The description of an ancient amphibian that millions of years ago swam in quiet pools and caught mayflies on the surrounding land in Texas has set to rest one of the greatest current controversies in vertebrate evolution. The discovery was made by a research team led by scientists at the... view more (2008-05-22)

Relocation of endangered Chinese turtle may save species
There are only four specimens of the Yangtze giant softshell turtle left on Earth-one in the wild and three in captivity.   view more (2008-05-22)

Priority regions for threatened frog and toad conservation in Latin America
Nearly 35% of all amphibians are now threatened of extinction raising them to the position of the most endangered group of animals in the world.   view more (2008-05-07)

65-million-year-old asteroid impact triggered a global hail of carbon beads
The asteroid presumed to have wiped out the dinosaurs struck the Earth with such force that carbon deep in the Earth's crust liquefied, rocketed skyward, and formed tiny airborne beads that blanketed the planet.   view more (2008-05-06)

Refining the date of the K/T boundary and the dinosaur extinction
Scientists at the University of California, Berkeley, and the Berkeley Geochronology Center have pinpointed the date of the dinosaurs' extinction more precisely than ever thanks to refinements to a common technique for dating rocks and fossils.   view more (2008-04-25)

Medical College researchers find dinosaur clues in fat
A team of researchers at New York Medical College has discovered why birds, unlike mammals, lack a tissue that is specialized to generate heat.   view more (2008-04-24)

Geologists Discover New Way of Estimating Size and Frequency of Meteorite Impacts
Scientists have developed a new way of determining the size and frequency of meteorites that have collided with Earth.   view more (2008-04-14)

New study changes conditions for Spanish brown bears
Brown bears from the Iberian Peninsula are not as genetically different from other brown bears in Europe as was previously thought.   view more (2008-03-19)

The song doesn't remain the same in fragmented bird populations
The song of passerine birds is a conspicuous and exaggerated display shaped by sexual selection in the context of male-male competition or mate attraction. At the level of the individual, song is considered an indicator of male 'quality'.   view more (2008-03-19)

Asia's odd-ball antelope faces migration crisis
Take a deer's body, attach a camel's head and add a Jimmy Durante nose, and you have a saiga - the odd-ball antelope with the enormous schnoz that lives on the isolated steppes of Central Asia.   view more (2008-03-18)

Clovis-age overkill didn't take out California's flightless sea duck
Clovis-age natives, often noted for overhunting during their brief dominance in a primitive North America, deserve clemency in the case of California's flightless sea duck. New evidence says it took thousands of years for the duck to die out.   view more (2008-03-18)

Destruction of Sumatra forests driving global climate change and species extinction
Turning just one Sumatran province's forests and peat swamps into pulpwood and palm oil plantations is generating more annual greenhouse gas emissions than the Netherlands and rapidly driving the province's elephants into extinction, a new study by WWF and partners has found.   view more (2008-02-27)

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)

Science, not romance, controls mating at Smithsonian's National Zoo
This Valentine's Day, Cupid won't be making a stop at the Smithsonian's National Zoo. Unlike the spontaneous attraction that most humans equate with love and romance, mating and dating at the National Zoo is planned, strategic and science-based-quite an unromantic encounter.   view more (2008-02-11)

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)

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)
