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)
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)
Volcanic eruptions, ancient global warming linked
A team of scientists announced today confirmation of a link between massive volcanic eruptions along the east coast of Greenland and in the western British Isles about 55 million years ago and a period of global warming that raised sea surface temperatures by five degrees (Celsius) in the tropics and more than six degrees in the Arctic. view more (2007-04-27)
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)
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 capable of sparking mass species extinctions
The Earth could see massive waves of species extinctions around the world if global warming continues unabated, according to a new study published in the scientific journal Conservation Biology. view more (2006-04-12)
Global warming increases species extinctions worldwide
Global warming has already caused extinctions in the most sensitive habitats and will continue to cause more species to go extinct over the next 50 to 100 years, confirms the most comprehensive study since 2003 on the effects of climate change on wild species worldwide by a University of Texas at Austin biologist. view more (2006-11-15)
Big bang in Antarctica — killer crater found under ice
Planetary scientists have found evidence of a meteor impact much larger and earlier than the one that killed the dinosaurs — an impact that they believe caused the biggest mass extinction in Earth's history. view more (2006-06-02)
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)
Mass extinction's cause: 'Sick Earth'
What really caused the largest mass extinction in Earth's history? view more (2006-10-23)
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)
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)
Hermaphroditic plants have genetic advantage in areas where extinctions are frequent
In one of the first studies to empirically compare the reproductive success of hermaphrodites and male and female populations, biologists from the University of Oxford make use of the rare and extreme sexual diversity displayed in a species of European weed to test the hypothesis that hermaphrodites have been selected in regions with frequent... view more...

Common garden plant threatened by climate change
Cyclamen, a common, pretty garden flower, is at risk of extinction because of climate change. In a study published today in the open access journal BMC Evolutionary Biology (http://www.biomedcentral.com/bmcevolbiol/), researchers show, using mathematical modelling, that the ideal climate for Cyclamen will become increasingly rare and might have... view more...

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)
Brain structure associated with fear inhibition also may influence personality
The relationship between the size of a brain structure and the ability to recover from traumatic experiences also may influence overall personality type. view more (2005-11-28)
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)
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 kangaroos. view more (2008-10-16)
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)
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)
