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 oceans. view more (2006-11-27)
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)
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 idea with new fossil data and math. view more (2008-09-12)
Extinction
Two teams of British scientists have produced the best evidence yet that our planet is experiencing a mass extinction. Two separate papers, published in Science 19 March and funded largely by the Natural Environment Research Council (NERC) highlight the serious concerns that have been growing among the world's scientists for over ten years. John... view more... (2004-03-18)
MIT IDs mechanism behind fear
Researchers from MIT's Picower Institute for Learning and Memory have uncovered a molecular mechanism that governs the formation of fears stemming from traumatic events. view more (2007-07-16)
Experts develop global action plan to save amphibians facing extinction
A summit of leading scientists have agreed to an action plan intended to save hundreds of frogs, salamanders and other amphibians facing extinction from familiar threats such as pollution and habitat destruction, as well as a little-known fungus wiping out their populations. view more (2005-09-21)
Far more than a meteor killed dinos
There's growing evidence that the dinosaurs and most their contemporaries were not wiped out by the famed Chicxulub meteor impact, 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 (2006-10-24)
Fossil record supports evidence of impending mass extinction
Global temperatures predicted for the coming centuries may trigger a new 'mass extinction event', where over 50 per cent of animal and plant species would be wiped out, warn scientists at the Universities of York and Leeds. view more (2007-10-24)
Death by hyperdisease
It took less than a decade for native rats to become extinct on the Indian Ocean's previously uninhabited Christmas Island once Eurasian black rats jumped ship onto the island at the turn of the 20th century. view more (2008-11-05)
Mangrove-dependent animals globally threatened
More than 40 percent of a sample of amphibians, reptiles, mammals, and birds that are restricted to mangrove ecosystems are globally threatened with extinction, according to an assessment published in the July/August issue of BioScience. view more (2009-07-01)
Current mass extinction spurs major study of which plants to save
The Earth is in the midst of the sixth mass extinction of both plants and animals, with nearly 50 percent of all species disappearing, scientists say. view more (2008-10-21)
New study pinpoints epicenters of Earth's imminent extinctions
Safeguarding 595 sites around the world would help stave off an imminent global extinction crisis, according to new research published today in the Proceedings of the National Academy of Sciences. view more (2005-12-13)
Surviving mass extinction by leading a double life
Drifting across the world's oceans are a group of unicellular marine microorganisms that are not only a crucial source of food for other marine life - but their fossils, which are found in abundance, provide scientists with an extraordinary record of climatic change and other major events in the history of the earth. view more (2009-07-15)
Avian Persistence in Fragmented Rainforest
Loss and deterioraton of indigenous habitat increasingly affect natural populations worldwide. As a result of these processes, new selection pressures are imposed upon organisms, increasing local extinction rates. Simultaneously, reduced movement among remnant patches lowers colonisation rates and affects demographic and genetic population... view more... (2002-11-08)
