Is Biology Fieldwork In Schools Following The Dodo?
Biology fieldwork could be heading for extinction according to a report to be published on Friday 18 October by the Field Studies Council and the British Ecological Society. This loss of opportunity would rob young people of the rich personal benefits of out of school experiences as well as the educational value of such trips. Professor John Grace... view more...

Oxygen increase caused mammals to triumph, researchers say
The first, high resolution continuous record of oxygen concentration in the earth's atmosphere shows that a sharp rise in oxygen about 50 million years ago gave mammals the evolutionary boost they needed to dominate the planet. view more (2005-09-30)
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)
Study of islands reveals surprising extinction results
It's no secret that humans are having a huge impact on the life cycles of plants and animals. UC Santa Barbara's Steven D. Gaines and fellow researcher Dov Sax decided to test that theory by studying the world's far-flung islands. view more (2008-08-27)
Extinction threats grow as sea governance rules ignored
Those who rule the ocean waves are being named and shamed today for their role in failing to prevent the near extinction of the albatross. view more (2005-03-03)
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)
Was male domination deadly for dinosaurs?
Dinosaurs suddenly died out because they gave birth to too many males as a result of climate change. This is the theory put forward by David Miller of medicine and Jonathen Summers of mechanical engineering at the University of Leeds. They believe that dinosaur populations died out because the sex of their offspring was determined by temperature.... view more... (2004-05-10)
History and timing of human impact on Lake Victoria, East Africa
Lake Victoria, the world's largest tropical lake, suffers from severe eutrophication and the probable extinction of up to half its 500+ species of endemic cichlid fishes. New sediment-core data show that increased algal production developed from the 1930s onwards, paralleling human population growth and agricultural activity in the surrounding... view more...

Ancient diets of Australian birds point to big ecosystem changes
A shifting diet of two flightless birds inhabiting Australia tens of thousands of years ago is the best evidence yet that early humans may have altered the continent's interior with fire, changing it from a mosaic of trees, shrubs and grasses to the desert scrub evident today, according to a University of Colorado at Boulder-led team. view more (2005-07-07)
Pre-clinical study suggests how steroid can reverse post-traumatic stress
Researchers at UT Southwestern Medical Center, working with mice, have shown how the body's own natural stress hormone can help lastingly decrease the fearful response associated with reliving a traumatic memory. view more (2006-09-13)
Humans lend a hand to critically endangered waterbird
Human impact on one of the world's most threatened bird species can be beneficial rather than destructive - and could even save it from extinction - according to counterintuitive new findings by the University of East Anglia (UEA). view more (2009-07-27)
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)
Female Antarctic seals give cold shoulder to local males
Female Antarctic fur seals will travel across a colony to actively seek males which are genetically diverse and unrelated, rather than mate with local dominant males. view more (2007-02-08)
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)
Coexistence of identical competitors: an old doctrine challenged
An illustrious principle in ecology states that no two identical species may coexist: sooner or later all but one will drift to extinction. Researchers from the Beijing Normal University and the University of Helsinki have modeled recent data on fig-pollinating wasps that appear to contradict the old theory. The model, which is reported in a... view more... (2004-02-24)
Plant fossils give first real picture of earliest Neotropical rainforests
A team of researchers including a University of Florida paleontologist has used a rich cache of plant fossils discovered in Colombia to provide the first reliable evidence of how Neotropical rainforests looked 58 million years ago. view more (2009-10-16)
Varied diet of early hominid casts doubt on extinction theory, says Colorado U study
An upright hominid that lived side by side with direct ancestors of modern humans more than a million years ago had a far more diverse diet than once believed, clouding the notion that it was driven to extinction by its picky eating habits as the African continent dried, says a new University of Colorado at Boulder study. view more (2006-11-10)
Large size crucial for Amazon forest reserves
An international research team has discovered that the size of Amazon forest reserves is yet more important than previously thought. view more (2007-01-12)
U of M study identifies medication that helps people with obsessive-compulsive disorder
Researchers at the University of Minnesota have found that a drug originally developed to fight tuberculosis may help people with obsessive-compulsive disorder make more progress in therapy sessions. view more (2007-07-20)
Sudden collapse in ancient biodiversity: Was global warming the culprit?
Scientists have unearthed striking evidence for a sudden ancient collapse in plant biodiversity. A trove of 200 million-year-old fossil leaves collected in East Greenland tells the story, carrying its message across time to us today. view more (2009-06-19)
