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 Austin biologist. view more (2006-11-15)
New Explanation for a Puzzling Biological Divide Along the Malay Peninsula
Ecologists at the University of California, San Diego, offer a new explanation for an apparently abrupt switch in the kinds in of mammals found along the Malay Peninsula in southeast Asia - from mainland species to island species - in the absence of any geographical barrier. view more (2009-03-06)
CMU researcher publishes anole lizard findings
Hundreds of species of anoles roam the Caribbean Islands and parts of North and South America, a highly diverse and colorful small lizard that scientists have studied in hopes of unlocking the secrets of evolution. view more (2007-03-07)
Bee species outnumber mammals and birds combined
Scientists have discovered that there are more bee species than previously thought. In the first global accounting of bee species in over a hundred years, John S. Ascher, a research scientist in the Division of Invertebrate Zoology at the American Museum of Natural History, compiled online species pages and distribution maps for more than 19,200... view more...

New dinosaur species possible in Northwestern Alberta
The discovery of a gruesome feeding frenzy that played out 73 million years ago in northwestern Alberta may also lead to the discovery of new dinosaur species in northwestern Alberta. view more (2009-05-13)
Opening a can of worms: Serendipitous discovery reveals earthworms more diverse than first thought
Scientists have found that the UK's common or garden earthworms are far more diverse than previously thought, a discovery with important consequences for agriculture. view more (2008-10-10)
2006 is banner year for discoveries of new species in Borneo's rainforests
Scientists have discovered at least 52 new species of animals and plants this past year on the island of Borneo. The discoveries, described in a new WWF report, include 30 unique fish species, two tree frog species, 16 ginger species, three tree species and one large-leafed plant species. view more (2006-12-19)
Keeping It In The Family
Blood really can be thicker than water in the insect world, a team of biologists at The University of Nottingham say in the journal Nature this week. The researchers, studying the unusual life-cycle of a parasitic wasp, found its larvae refused to attack close relatives even under extreme starvation conditions. Led by Dr Ian Hardy in the School... view more... (2004-08-02)
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)
Bird flu claims critically endangered mammal
A far wider range of wildlife species could be at risk from bird flu, warns a biologist from the University of East Anglia. view more (2005-08-30)
Soil fungi affect parasitism of foliage-feeding insects
Recent studies have shown the importance of links between soil organisms and those feeding above-ground. However, to date these have involved two or three trophic levels, because it has been assumed that the effects weaken as one progresses up or down a food chain. In a forthcoming paper in Ecology Letters, Gange, Brown & Aplin show that... view more... (2003-11-24)
How to share a bat
New research shows how different species of plants evolve unique floral adaptations in order to transfer pollen on different regions of bats' bodies, thus allowing multiple plant species to share bats as pollinators. view more (2007-08-23)
For some species, an upside to inbreeding
Although breeding between close kin is thought to be generally unfavorable from an evolutionary standpoint, in part because harmful mutations are more easily propagated through populations in this way, theory predicts that under some circumstances, the benefits of inbreeding may outweigh the costs. view more (2007-02-06)
Genetics reveals big fish that almost got away
Researchers from the University of Hawaii, the Wildlife Conservation Society, Smithsonian Tropical Research Institute, National Marine Fisheries Service and Projecto Meros do Brazil discovered a new species of fish-a grouper that reaches more than six feet in length and can weigh nearly 1,000 pounds. This newly discovered species can be found... view more... (2008-08-22)
Climate change predicted to drive trees northward
The most extensive and detailed study to date of 130 North American tree species concludes that expected climate change this century could shift their ranges northward by hundreds of kilometers and shrink the ranges by more than half. view more (2007-12-03)
Priority regions for threatened frog and toad conservation in Latin America
Nearly 35% of all amphibians are now threatened of extinction raising them to the position of the most endangered group of animals in the world. view more (2008-05-07)
Mysterious mountain dino may be a new species
A partial dinosaur skeleton unearthed in 1971 from a remote British Columbia site is the first ever found in Canadian mountains and may represent a new species, according to a recent examination by a University of Alberta researcher. view more (2008-06-13)
War and the humanitarian response
Psychology could be the key to healing the emotional impact of war on civilians throughout the world. However, psychologists should ensure that their methods do not conflict with traditional beliefs and methods of coping. view more (2002-02-27)
Cellular organelle evolved repeatedly
NWO researchers have discovered that in the course of evolution hydrogenosomes repeatedly evolved from mitochondria. Hydrogenosomes, or 'hydrogen-forming organelles', are cell organelles that produce hydrogen and energy. They serve as an alternative energy supply in organisms that live without oxygen, such as anaerobic fungi and protozoa. The... view more... (2001-07-26)
Seeing the wood for the trees: research reveals the survival secrets of forest trees
Species extinction or `biodiversity loss` has accelerated at an alarming rate over the past century. Although much of the blame has been laid at the door of human activity, biologists are looking at the factors that influence how species-particularly similar species-co-exist, in their efforts to better understand how the balance of species can be... view more...
