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)
Coral reef fish harbor an unexpectedly high biodiversity of parasites
IRD researchers showed that Epinephilus maculates, a fairly abundant species of grouper off New Caledonia, was parasitized by 12 species of microscopic monogenean worms. view more (2007-09-06)
New population of highly threatened greater bamboo lemur found in Madagascar
Researchers in Madagascar have confirmed the existence of a population of greater bamboo lemurs more than 400 kilometers (240 miles) from the only other place where the Critically Endangered species is known to live, raising hopes for its survival. view more (2008-07-22)
Why does species diversity vary so much?
The diversity of life varies predictably with climate and is greatest where it is warm and wet (the humid tropics). But the question "why" has puzzled biologists for over a century. In the December issue of Ecology Letters, Currie and colleagues examine three hypotheses about the origin of climatic gradients of diversity. The... view more... (2005-01-11)
Manipulating biotope space can enhance beneficial biodiversity effects
Using diverse plant mixtures instead of monocultures can increase yield and other ecosystem goods and services on which humans depend. Recent studies showed that such beneficial effects of biodiversity depend on complementarity between species in resource use, as is the case if species root in different soil depths. This knowledge led to the... view more... (2004-06-10)
Looking beyond biodiversity to explain community invasibility
Most existing experimental and theoretical studies suggest that diversity is an effective barrier to plant invasion. However, these studies may be limited in their generality, because they involve relatively small numbers of species or examine only short time periods. To evaluate how invasions are controlled in more realistic situations, Meiners,... view more... (2004-02-05)
Common garden plant threatened by climate change
Cyclamen, a common, pretty garden flower, is at risk of extinction because of climate change. In a study published today in the open access journal BMC Evolutionary Biology (http://www.biomedcentral.com/bmcevolbiol/), researchers show, using mathematical modelling, that the ideal climate for Cyclamen will become increasingly rare and might have... view more...

Canada's pristine freshwater fisheries at risk
If you want to catch a trophy northern pike, walleye or brook trout in the northern Canadian wilderness, better plan your trip soon. That's because according to a report released today by the Wildlife Conservation Society, looming development, including forestry, mining and dam construction, threatens this pristine region of untouched forests,... view more...

Deft diving turtle tactics
How do turtles survive long trips across the ocean? At the Society for Experimental Biology conference on Friday 12 April Ms Corinne Martin (University of Wales Swansea) will present evidence of energy-saving diving patterns adopted by green turtles to survive long ocean trips. The turtles breed at Ascension Island, undertaking long-distance... view more... (2002-04-04)
Climate change threatens a million species with extinction
Climate change may drive a quarter of land animals and plants extinct, according to a major new study published in the journal Nature - unless greenhouse gas emissions are drastically reduced. The largest collaboration of scientists ever to apply themselves to this problem studied six biodiversity-rich regions around the world representing 20% of... view more... (2004-01-07)
World interest in Australian fishery impact test
An Australian method for assessing the environmental impact of marine fisheries has caught the eye of fishery management agencies worldwide. view more (2009-10-28)
How butterflies got their spots: A 'supergene' controls wing pattern diversity
Butterflies are known to employ some interesting convergent evolutionary tactics to survive-some nonpoisonous species have similar wing patterns to those of noxious species that predators avoid. view more (2006-09-26)
Human activity destroys species that the Ice Age could not
Forest clearance and animal overgrazing in the last 5,000 years have destroyed important tree species that had survived even the Ice Age. Dr Mick Frogley, Lecturer in Physical Geography at the University of Sussex, is one of a British research team exploring a site near Lake Ioannina in the Pindus Mountains of northwestern Greece. "Given the... view more... (2002-09-20)
Genetic study finds treasure trove of new lizards
University of Adelaide research has discovered that there are many more species of Australian lizards than previously thought, raising new questions about conservation and management of Australia's native reptiles. view more (2009-03-04)
Microchip saves rare turtle from soup-pot
An extremely rare "royal" turtle narrowly escaped a trip to a Chinese soup-pot, thanks to a tiny microchip implanted in its skin, according to experts from the New York-based Wildlife Conservation Society (WCS), who rediscovered the species four years ago in Cambodia. view more (2005-07-19)
Biodiversity promotes evolutionary change
Evolutionary biologists at the University of East Anglia have discovered a new link between biodiversity and the evolution of new species. view more (2005-04-18)
New host species for avian influenza identified
In a new study published online in the open-access journal PLoS Pathogens, Dr. Vincent J. Munster, of Erasmus Medical Center, Rotterdam, and colleagues identify new host species for avian influenza A virus (H5N1) and provide important information on the distinctions between the ecology and epidemiology of various global strains of the virus. view more (2007-05-11)
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)
Leading Scientists Design New Framework for Biodiversity Conservation
A new study published in the August issue of Ecology Letters shows that elaborate modeling efforts used to guide land conservation result in plans that are rarely achievable in the real world and may actually be counter-productive to achieving long term protection of plants and animals. Author Sandy Andelman says "Conservation agencies are... view more... (2004-08-19)
Beautiful plumage: Feather color and sex start the species revolution
Faculty of 1000, the leading scientific evaluation service, has highlighted research providing evidence for the evolution of a new species. view more (2009-08-06)
