New NOAA report offers in-depth look at Northwestern Hawaiian islands marine life, ecosystems
A new NOAA report on the Northwestern Hawaiian Islands (NWHI), protected by the Papahānaumokuākea Marine National Monument, provides the sharpest picture yet of the region's marine life and ecosystems. view more (2009-05-22)
Brown Scientist Finds Coastal Dead Zones May Benefit Some Species
Coastal dead zones, an increasing concern to ecologists, the fishing industry and the public, may not be as devoid of life after all. A Brown scientist has found that dead zones do indeed support marine life, and that at least one commercially valuable clam actually benefits from oxygen-depleted waters. view more (2008-10-15)
Study shows that parasites form the thread of food webs
Scientists have discovered that parasites are suprisingly important in food webs and their findings appear in a report published this week in the Early Edition of the on-line version of the Proceedings of the National Academy of Sciences. view more (2006-07-13)
From the egg, baby crocodiles call to each other and to mom
For the first time, researchers have shown that the pre-hatching calls of baby Nile crocodiles actually mean something to their siblings and to their mothers. view more (2008-06-24)
Parasites Outweigh Predators in Pacific Coast Estuaries
In a study of parasites living in three estuaries on the Pacific coast of California and Baja California, researchers have determined that biomass of these parasites exceeds that of top predators, in some cases by more than 20 times. view more (2008-07-24)
Are wolves the pronghorn's best friend?
As western states debate removing the gray wolf from protection under the Endangered Species Act, a new study by the Wildlife Conservation Society cautions that doing so may result in an unintended decline in another species: the pronghorn, a uniquely North American animal that resembles an African antelope. view more (2008-03-04)
Wolves, moose and biodiversity: An unexpected connection
Moose eat plants; wolves kill moose. What difference does this classic predator-prey interaction make to biodiversity? view more (2009-11-02)
Mussels evolve quickly to defend against invasive crabs
Scientists at the University of New Hampshire (UNH) have found that invasive crab species may precipitate evolutionary change in blue mussels in as little as 15 years. view more (2006-08-11)
Biologists expose hidden costs of firefly flashes
A new study by biologists at Tufts University has discovered a dark side lurking behind the magical light shows put on by fireflies each summer. Using both laboratory and field experiments to explore the potential costs of firefly courtship displays, the biologists have uncovered some surprising answers. view more (2007-09-20)
Alarm pheromone causes aphids to sprout wings
Chemical communication within insect species is often much more sophisticated than expected. When aphids are attacked by predators such as ladybird beetles, they release an alarm pheromone, (E)-ß-farnesene, that has long been known to cause other aphids to walk around or drop from the plant. view more (2005-05-18)
Chimpanzee cooperators
In the animal kingdom cooperation is crucial for survival. Predators hunt in prides and prey band together to protect themselves. Yet no other creature cooperates as successfully as we do. view more (2006-03-03)
Ambient light influences the evolution of colour signals
In light-contrasted ecosystems, ambient light and background colours influence the evolution of animal coloration. Because maximal conspicuousness is achieved for signals which are rich in the colours of ambient light but poorly reflected by background, different signals will be cryptic or conspicuous at different heights in tropical rainforest.... view more...

Researchers to study rebirth of an island after volcanic eruption
When Alaska's Kasatochi Volcano erupted on Aug. 7, 2008, it virtually sterilized Kasatochi Island, covering the small Aleutian island with a layer of ash and other volcanic material several meters thick. view more (2009-08-07)
Primates harvest bee nests in Ugandan reserve
In the first study of native African honeybees and honey-making stingless bees in the same habitat, humans and chimpanzees are the primary bee nest predators. view more (2006-02-28)
Presence of wolves allows aspen recovery in Yellowstone
The wolves are back, and for the first time in more than 50 years, young aspen trees are growing again in the northern range of Yellowstone National Park. view more (2007-07-27)
Tropical crab invades Georgia oyster reefs -- but the long-term impact can't be predicted
A dime-sized tropical crab that has invaded coastal waters in the Southeast United States is having both positive and negative effects on oyster reefs, leaving researchers unable to predict what the creature's long-term impact will be. view more (2007-09-05)
UAB Research Team Working to Keep Terrapin Turtle Off Endangered Species List
University of Alabama at Birmingham (UAB) researchers exploring strategies for conserving the Diamondback Terrapin along Alabama's Dauphin Island coastline are working to keep the once-celebrated turtle off the endangered species list. view more (2009-09-23)
Chasing high flying insects with radar
New developments to vertical looking radar (VLR) mean that scientists at Rothamsted, Harpenden are now tracking insects to find out where they go and how they behave when they take to the skies. "The sheer abundance of insects is amazing," says Dr Alan Smith of Rothamsted Radar Entomology Unit. "The actual biomass of insects above us on a... view more... (2002-06-26)
Wolves lose their predatory edge in mid-life, new U of Minnesota study shows
Although most wolves in Yellowstone National Park live to be nearly six years old, their ability to kill prey peaks when they are two to three, according to a study led by Dan MacNulty and recently published online by Ecology Letters. view more (2009-10-27)
Counting sheep in climate change predictions
Climate change can have devastating effects on endangered species, but new mathematical models may be able to aid conservation of a population of bighorn sheep. view more (2009-06-01)
