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)
Camera-shy deer caught for first time
A little-known species of deer called a large-antlered muntjac has been photographed for the first time in the wild, according to a survey team from the Nam Theun 2 Watershed Management and Protection Authority (WMPA) and the Wildlife Conservation Society view more (2007-07-25)
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)
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)
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)
Zoologists: Sea snakes seek out freshwater to slake thirst
Sea snakes may slither in saltwater, but they sip the sweet stuff. So concludes a University of Florida zoologist in a paper appearing this month in the online edition of the November/December issue of the journal Physiological and Biochemical Zoology. view more (2008-11-07)
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...

Silent Streams? Escalating Endangerment for North American Freshwater Fish: Nearly 40 Percent Now At-Risk
Nearly 40 percent of fish species in North American streams, rivers and lakes are now in jeopardy, according to the most detailed evaluation of the conservation status of freshwater fishes in the last 20 years. view more (2008-09-10)
LSU professor discovers new species
Chris Austin, assistant curator of herpetology at LSU's Museum of Natural Science, or LSUMNS, and adjunct professor in biological sciences, recently discovered a new species of lizard while conducting field research in Borneo. view more (2006-12-12)
Great legs - rainforest birds` essential survival kit
Finely shaped legs are not just objects of beauty - some contain an important message. The legs of rainforest birds tell a story of environmental degradation. These bird's legs grow while they are in the nest being fed by their parents. When they leave the nest, they are fully grown. But the legs of some rainforest species show a curious pattern -... view more... (2002-11-12)
Why do some queen bees eat their worker bee's eggs?
Worker bees, wasps, and ants are often considered neuter. But in many species they are females with ovaries, who although unable to mate, can lay unfertilized eggs which turn into males if reared. view more (2006-12-05)
Climate change could trigger 'boom and bust' population cycles leading to extinction
Climate change could trigger "boom and bust" population cycles that make animal species more vulnerable to extinction. , according to Christopher C. Wilmers, an assistant professor of environmental studies at the University of California, Santa Cruz. view more (2007-04-17)
Urgent action on international coral reef crisis
Coral reef scientists and policy makers from the world's most prominent coral reef nations are meeting in Australia this week to develop urgent action plans to rescue the world's richest centre of marine biodiversity from gradual decline. view more (2008-11-10)
Report Warns about Carbon Dioxide Threats to Marine Life
Worldwide emissions of carbon dioxide from fossil fuel burning are dramatically altering ocean chemistry and threatening marine organisms, including corals, that secrete skeletal structures and support oceanic biodiversity. view more (2006-07-06)
Major initiative proposed to address amphibian crisis
Fifty of the leading amphibian researchers in the world have called for a new Amphibian Survival Alliance, a $400 million initiative to help reduce and prevent amphibian declines and extinctions, an ecological crisis of growing proportion that is continuing to get worse. view more (2006-07-07)
Toad tadpoles and the 'Laurel and Hardy' effect
Research at the University of Kent has revealed a remarkable phenomenon among tadpoles of the Mallorcan midwife toad, one of Europe's most threatened species. The researchers, from the University's Durrell Institute for Conservation and Ecology, (DICE) have discovered that the toad tadpoles can change shape when they smell snakes swimming nearby.... view more...

Students discover new species of spider
As film buffs queue to watch the new Spider-man movie, geography students from the University of Sussex have gone one better by discovering a new species of spider in the wild. The second year undergraduates were taking part in a field course to the Seychelles, one of the most biologically diverse places on the planet. As part of this trip the... view more... (2002-07-04)
