California's Ancient Kelp Forest
The kelp forests off southern California are considered to be some of the most diverse and productive ecosystems on the planet, yet a new study indicates that today's kelp beds are less extensive and lush than those in the recent past. view more (2009-11-12)
Amphibians as environmental omen disputed
Amphibians, for years considered a leading indicator of environmental degradation, are not uniquely susceptible to pollution, according to a meta-analysis to be published in Ecology Letters. view more (2009-11-12)
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)
Eutrophication affects diversity of algae
Eutrophication of the seas may have an impact on genetic variation in algae, research at the University of Gothenburg shows. view more (2009-10-20)
Herbivory discovered in a spider
There are approximately 40,000 species of spiders in the world, all of which have been thought to be strict predators that feed on insects or other animals. Now, scientists have found that a small Central American jumping spider has a uniquely different diet: the species Bagheera kiplingi feeds predominantly on plant food. view more (2009-10-13)
Sheep that shed light on personality differences
The team led by Denis Reale, a professor in the Department of Biological Sciences at UQAM and Canada Research Chair in Behavioural Ecology, recently completed a study showing the link between personality, survival and reproductive success in male bighorn sheep. view more (2009-09-16)
Small rodents encourage the formation of scrubland in Spain
After two years of research over five degraded landscapes in the National Park of Sierra Nevada (Granada), scientists have established for the first time that field mice base their diet on holm oak and pine seeds, causing a deterioration of the habitats and an extension of scrubland in the forests. view more (2009-08-28)
Do the media lead entrepreneurs astray?
If you're looking for reliable information, then you won't necessarily find it in the newspaper. According to Dr. Susan Glover from the University of California in the US, public information from both informal and written sources, like newspapers, leads entrepreneurs astray. view more (2009-08-27)
Scientists demonstrate importance of niche differences in biodiversity
Scientists at UC Santa Barbara have found strong evidence that niche differences are critical to biodiversity. Their findings are published online in this week's issue of the journal Nature. view more (2009-08-13)
The Value of Variation: Ecologists Consider the Causes and Consequences
Consider the case of the three-spine stickleback. These tiny fish that thrive in oceans and in fresh water might appear to be the same, yet ecologists are finding that they are actually a diverse collection of very specialized individuals. view more (2009-07-23)
AIDS discovered in wild chimpanzees
Although the AIDS virus (HIV-1) entered the human population through chimpanzees, scientists have long believed that chimpanzees don't develop AIDS. view more (2009-07-23)
Was SIDS the cause of infant deaths even 150 years ago?
19th century infant deaths attributed to smothering and overlaying, by either a co-sleeper or bedding, were in all likelihood crib deaths, or Sudden Infant Death Syndrome (SIDS). view more (2009-07-15)
Climate change may spell demise of key salt marsh constituent
Global warming may exact a toll on salt marshes in New England, but new research shows that one key constituent of marshes may be especially endangered. view more (2009-07-13)
Male seahorses like big mates
Male seahorses have a clear agenda when it comes to selecting a mating partner: to increase their reproductive success. view more (2009-07-08)
Plants' internal clock can improve climate-change models
The ability of plants to tell the time, a mechanism common to all living beings, enables them to survive, grow and reproduce. view more (2009-07-06)
A thirst for blood sparks toxic algal blooms
The blooming of toxic algae that occurs during the summer conceal a fight for life and death. Scientists at the University of Gothenburg propose in an article published in the journal PNAS that algal blooms are created when aggressive algae kill and injure their competitors in order to absorb the nutrients they contain. view more (2009-06-30)
Mate selection: How does she know he'll take care of the kids?
Throughout the animal kingdom brilliant colors or elaborate behavioral displays serve as "advertisements" for attracting mates. view more (2009-06-18)
Moms, have you done drugs? Tell your kids
Moms who have used drugs may be doing their teens a favour by admitting to it, University of Alberta research shows. view more (2009-06-10)
Scientists find formula to uncover our planet's past and help predict its future
Studies of climate evolution and the ecology of past-times are often hampered by lost information - lost variables needed to complete the picture have been long thought untraceable but scientists have created a formula which will fill in the gaps of our knowledge and will help predict the future. view more (2009-05-27)
U of Minnesota research reveals critical role of evolutionary processes in species coexistence
A team of researchers, led by the University of Minnesota, addressing long-standing conflicts in ecology and evolutionary science, has provided key directions for the future of community ecology. view more (2009-05-22)
