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)
Birds going extinct faster due to human activities
Human activities have caused some 500 bird species worldwide to go extinct over the past five millennia, and 21st-century extinction rates likely will accelerate to approximately 10 additional species per year unless societies take action to reverse the trend, according to a new report. view more (2006-07-06)
Reproductive speed protects large animals from being hunted to extinction
The slower their reproductive cycle, the higher the risk of extinction for large grazing animals such as deer and antelope that are hunted by humans. view more (2007-05-16)
NOAA proposes federal regulations to protect black abalone
NOAA Fisheries Service published with the Federal Register today a proposed rule to list black abalone, a marine mollusk coveted by fishermen and gourmets alike, as endangered under the Endangered Species Act (ESA). view more (2008-01-14)
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)
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)
Volcanoes, asteroids and mass extinctions
Neither massive volcanic eruptions nor extraterrestrial impacts are sufficiently powerful on their own to cause mass extinctions of life on Earth, research by University of Leicester geologists suggests. Instead, both events coincidentally occurring together may be required to cause the worst mass extinctions. In the last 300 million years, life... view more... (2004-05-17)
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)
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)
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)
Mass flowering crops enhance pollinator densities at a landscape scale
The EU response to recent declines in pollinators and consequent loss of pollination services has been the inclusion of pollinator-friendly management in agri-environment schemes. These comprise the promotion of semi-natural habitats, such as set-aside and field margin strips. Yet, mass flowering crops, such as oilseed rape, are assumed to be of... view more... (2003-10-08)
Breast Feeding May Not Protect Against Obesity
Breast feeding does not protect against overweight and obesity, according to two studies in this week's BMJ. The first study followed 2,250 male Brazilians for 18 years, for whom detailed breast feeding information was collected in early childhood. The results were mostly negative. Duration of breast feeding showed no association with several... view more... (2003-10-15)
Ethnic background may be associated with diabetes risk
Fat and muscle mass, as potentially determined by a person's ethnic background, may contribute to diabetes risk, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). view more (2009-10-06)
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)
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)
Researchers determine why wolves not dispersing as fast as expected in Yellowstone
In 1995, 14 wolves were transferred to Yellowstone National Park in the U.S. from the Canadian Rocky Mountains, with 17 more joining them the following year. view more (2006-11-02)
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)
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)
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)
