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 hope for the red squirrel
A number of red squirrels are immune to squirrelpox viral disease, which many believed would lead to the extinction of the species, scientists have discovered.   view more (2008-10-17)

UAF geologist studies Chicxulub impact crater
About 65 million years ago, a massive disruption led to worldwide extinction of dinosaurs. The impact of a giant asteroid created massive tsunamis and spewed forth a global cloud of carbon gases that altered Earth's atmosphere and blocked the light for weeks, possibly years. In recent years, that... view more (2007-01-19)

Oceans may soon be more corrosive than when the dinosaurs died
Increased carbon dioxide emissions are rapidly making the world's oceans more acidic and, if unabated, could cause a mass extinction of marine life similar to one that occurred 65 million years ago when the dinosaurs disappeared.   view more (2006-02-21)

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... view more (2008-08-12)

Climate change threatens a million species with extinction
Climate change may drive a quarter of land animals and plants extinct, according to a major new study published in the journal Nature - unless greenhouse gas emissions are drastically reduced. The largest collaboration of scientists ever to apply themselves to this problem studied six... view more (2004-01-07)

The species that propagate slowly, become extinct sooner
The animals and plants of our planet are becoming extinct under the pressure of civilization. The scientists have counted that one species vanishes from Earth every hour. The mammoth, passenger pigeon, gare-fowl, Steller`s sea cow - these are the most well-known of extinct species, but hundreds of... view more (2002-10-18)

Twenty of World's 162 Grouper Species Threatened With Extinction
The first comprehensive assessment of the world's 162 species of grouper, a culinary favorite and important commercial fish, found that 20 are threatened with extinction unless proper management or conservation measures are introduced.   view more (2007-03-22)

Cold is hot in evolution — UBC researchers debunk belief species evolve faster in tropics
University of British Columbia researchers have discovered that contrary to common belief, species do not evolve faster in warmer climates.   view more (2007-03-16)

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)

Climate change drives widespread amphibian extinctions
Results of a new study provide the first clear proof that global warming is causing outbreaks of an infectious disease that is wiping out entire frog populations and driving many species to extinction.   view more (2006-01-12)

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)

Good times ahead for dinosaur hunters, according to U of Penn scientist's dinosaur census
The golden age of dinosaur discovery is yet upon us, according to Peter Dodson at the University of Pennsylvania.   view more (2006-09-05)

Why are lions not as big as elephants?
Carnivores are some of the widest ranging terrestrial mammals for their size, and this affects their energy intake and needs.   view more (2007-01-16)

Global warming threatens Australia's iconic kangaroos
As concerns about the effects of global warming continue to mount, a new study published in the December issue of Physiological and Biochemical Zoology finds that an increase in average temperature of only two degrees Celsius could have a devastating effect on populations of Australia's iconic... view more (2008-10-16)

Race to halt global amphibian crisis boosted by rediscovery of endangered Colombian frogs
The rediscovery of two frog species feared extinct has made a new Colombian protected area the focal point for efforts to save amphibians from a deadly fungus decimating their populations in Central and South America.   view more (2006-06-07)

Tiny pikas seem to be on march toward extinction in Great Basin
The tiny rabbit-like American pika, an animal species considered to be one of the best canaries in a coal mine for detecting global warming in the western United States, appears to be veering toward the brink of extinction in the Great Basin.   view more (2005-12-29)

What we can learn from the biggest extinction in the history of Earth
Approximately 250 million years ago, vast numbers of species disappeared from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences.   view more (2007-08-10)

Smithsonian study concludes Caribbean extinctions occurred 2M years after apparent cause
Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth. The researchers summarized the environmental, ecological and evolutionary consequences for Caribbean shallow-water marine communities when... view more (2007-03-13)

The future of tropical forests
Deforestation and habitat loss are expected to lead to an extinction crisis among tropical forest species. Humans in rural settings contribute most to deforestation of extant tropical forests.   view more (2006-04-07)

Biodiversity loss linked to economic inequality worldwide
An interdisciplinary team of McGill researchers has uncovered a connection between growing economic inequality and an increase in the number of plant and animal species that are threatened with extinction.   view more (2007-05-16)

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)

Hot spots for cool birds
Global research highlighting the most important areas for albatross migration and breeding may yet help save these magical birds from extinction.   view more (2004-11-08)

Risk of extinction accelerated due to interacting human threats
The simultaneous effect of habitat fragmentation, overexploitation, and climate warming could accelerate the decline of populations and substantially increase their risk of extinction, a study published in the Proceedings of the Royal Society B has warned.   view more (2007-02-08)
