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... view more (2004-02-24)

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... 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)

New Breakthroughs in Geological Dating Imminent
A breakthrough in geological dating can be expected within the next few years, combining existing methods to yield higher accuracy over longer time scales closer to the earth's origin.   view more (2007-08-23)

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)

Soft tissue taken from Tyrannosaurus rex fossil yields original protein
What happens when a 68 million-year-old Tyrannosaurus Rex meets 21st century medical science? A North Carolina State University researcher and her colleagues at Harvard Medical School and Beth Israel Deaconess Medical Center found out when they confirmed the existence of protein in soft tissue... view more (2007-04-13)

Old bones unearth new date for giant deer's last stand
A new investigation into extinctions caused by climate change has revealed that the giant deer, previously thought to have been wiped out by a cold spell 10,500 years ago, instead survived well into the modern era.   view more (2004-10-04)

Size of brain structure could signal vulnerability to anxiety disorders
The size of a particular structure in the brain may be associated with the ability to recover emotionally from traumatic events. A new study by researchers from Massachusetts General Hospital (MGH) finds that an area called the ventromedial prefrontal cortex is thicker in volunteers who appear... view more (2005-07-12)

Global task force to save the albatross wins backing of The Prince of Wales
The Prince of Wales and record-breaking sailor, Ellen MacArthur, are together to trumpet global efforts to save one of the world's most endangered yet iconic birds.   view more (2005-04-26)

New global bird map suggests 'hotspots' not a simple key to conservation
The first full map of where the world's birds live reveals their diversity 'hotspots' and will help to focus conservation efforts, according to research published in Nature today (18 August).   view more (2005-08-18)

All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon... view more (2003-05-22)

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... view more (2006-11-15)

New modeling study forecasts disappearance of existing climate zones
A new climate modeling study forecasts the complete disappearance of several existing climates in tropical highlands and regions near the poles, while large swaths of the tropics and subtropics may develop new climates unlike any seen today.   view more (2007-03-28)

Why does species diversity vary so much?
The diversity of life varies predictably with climate and is greatest where it is warm and wet (the humid tropics). But the question "why" has puzzled biologists for over a century. In the December issue of Ecology Letters, Currie and colleagues examine three hypotheses about the origin... view more (2005-01-11)

New 150 Million-Year-Old Crab Species Discovered
Researchers from Kent State University and the University of Bucharest, Romania, have discovered a new primitive crab species Cycloprosopon dobrogea in eastern Romania. Previously unexamined, these ancient crabs from the Prosopidae family existed more than 150 million years ago during the Jurassic... view more (2007-10-18)

Brown tree snake could mean Guam will lose more than its birds
In the last 60 years, brown tree snakes have become the embodiment of the bad things that can happen when invasive species are introduced in places where they have few predators. Unchecked for many years, the snakes caused the extinction of nearly every native bird species on the Pacific island of... view more (2008-08-11)

The spread of our species
In a major new development in human evolutionary studies, researchers from the University of Cambridge argue that the dispersal of modern humans from Africa to South Asia may have occurred as recently as 70,000 years ago.   view more (2005-11-07)

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)

Study shows big game hunters, not climate change, killed off sloths
Prehistoric big game hunters and not the last ice age are the likely culprits in the extinction of giant ground sloths and other North American great mammals such as mammoths, mastodons and saber-toothed tigers, says a University of Florida researcher.   view more (2005-08-04)

Why an Allosaurus's butt is worse than its bite
At up to 12 metres long and weighing as much as two tonnes, the Allosaurus is recognised as having been one of the fiercest dinosaurs of the late Jurassic age. But its slender teeth and sometimes narrow jaw bone have left scientists puzzled as to how the Allosaurus managed to hunt prey... view more (2001-02-19)

FSU scientist warns North Atlantic right whale facing extinction
The North Atlantic right whale's future looks grim if the current mortality rates continue, according to Florida State University assistant professor of oceanography Douglas Nowacek and a group of fellow scientists from across the nation.   view more (2005-07-25)

New study explores patterns in species diversity and genetic diversity
As scientists, conservationists, and policy-makers wrestle with how to balance development with maintaining biodiversity, it's important to understand what controls patterns of biodiversity and how the biodiversity of a system will respond to different environmental scenarios.   view more (2005-07-27)

Duck-billed dinosaur crests not linked to sense of smell
After decades of debate, a U of T researcher has finally determined that duck-billed dinosaurs' massive but hollow crests had nothing to do with what many scientists suspected - the sense of smell.   view more (2006-01-25)

Gene expression in alligators suggests birds have 'thumbs'
The latest breakthrough in a 120 year-old debate on the evolution of the bird wing was published in the open-access journal PLoS ONE.   view more (2008-10-06)
