Evolution of new species slows down as number of competitors increases
The rate at which new species are formed in a group of closely related animals decreases as the total number of different species in that group goes up, according to new research published in PLoS Biology.   view more (2008-03-25)

Bacteria show promise in fending off global amphibian killer
First in a petri dish and now on live salamanders, probiotic bacteria seem to repel a deadly fungus being blamed for worldwide amphibian deaths and even extinctions.   view more (2007-05-23)

Biodiversity controls ecological 'services,' report scientists in comprehenisive analysis
Accelerating rates of species extinction pose problems for humanity, according to a comprehensive study headed by a biologist at the University of California, Santa Barbara and published in the journal Nature this week.   view more (2006-10-26)

What Makes The Scorpion`S Sting Deadly Poisonous?
Even the scorpion`s exterior warns that this is a dangerous animal. And it proves to be true, as nothing good comes out when small animals and even human beings meet with this arthropod species: its sting causes a sharp pain, some tropical scorpion`s sting is often fatal for the victim. The... view more (2002-03-15)

Smithsonian study concludes Caribbean extinctions occurred 2M years after apparent cause
Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth. The researchers summarized the environmental, ecological and evolutionary consequences for Caribbean shallow-water marine communities when... view more (2007-03-13)

Captive breeding introduced infectious disease to Mallorcan amphibians
A potentially deadly fungus that can kill frogs and toads was inadvertently introduced into Mallorca by a captive breeding programme that was reintroducing a rare species of toad into the wild, according to a new study published today in the journal Current Biology.    view more (2008-09-22)

Biodiversity conservation - no guarantee for shortcuts
New research from scientists at the University of Sheffield published in the November issue of Ecology Letters has cast doubts on the widely held `rule of thumb` that the conservation of a country`s biodiversity can be guaranteed by focusing on protecting its threatened and endemic species. In a... view more (2002-10-30)

Limited climate tracking in European trees despite 10,000 years of postglacial warmth
The relative roles of environment and history as controls of large-scale species distributions is a crucial issue in biogeography and macroecology. In the forthcoming issue of Ecology Letters Svenning & Skov use bioclimatic modelling to show that among 55 native European tree species, 36 occupy... view more (2004-06-10)

Competition between species curbs selfishness?
Animals are in constant competition over procreative resources. The interests of the individual and the population are not necessarily one and the same; aggressive insects may fare well in the mating competition, but eventually the proliferation of aggressive genes will weaken the procreative... view more (2004-12-20)

Extraterrestrial Impact Likely Source of Sudden Ice Age Extinctions
At the end of the Pleistocene era, wooly mammoths roamed North America along with a cast of fantastic creatures - giant sloths, saber-toothed cats, camels, lions, tapirs and the incredible teratorn, a condor with a 16-foot wingspan.   view more (2007-09-25)

Man may have caused pre-historic extinctions
New research shows that pre-historic horses in Alaska may have been hunted into extinction by man, rather than by climate change as previously thought.   view more (2006-05-05)

Dying frogs sign of a biodiversity crisis
Devastating declines of amphibian species around the world are a sign of a biodiversity disaster larger than just frogs, salamanders and their ilk, according to researchers from the University of California, Berkeley.   view more (2008-08-13)

More species in the tropics because species have been there longer
Why are there more species in the tropics than in the temperate regions of the globe? Many of the world's species live in the tropics (perhaps more than half), but the reason has been debated for more than 100 years.   view more (2006-11-02)

Dramatic shift from simple to complex marine ecosystems occurred 250M years ago at mass extinction
The earth experienced its biggest mass extinction about 250 million years ago, an event that wiped out an estimated 95% of marine species and 70% of land species. New research shows that this mass extinction did more than eliminate species: it fundamentally changed the basic ecology of the world's... view more (2006-11-27)

Meteor impacts: Life's jump starter?
Meteor impacts are generally regarded as monstrous killers and one of the causes of mass extinctions throughout the history of life.   view more (2005-08-09)

Cold is hot in evolution — UBC researchers debunk belief species evolve faster in tropics
University of British Columbia researchers have discovered that contrary to common belief, species do not evolve faster in warmer climates.   view more (2007-03-16)

New bacteria contaminate hairspray
Scientists in Japan have discovered a new species of bacteria that can live in hairspray, according to the results of a study published in the March issue of the International Journal of Systematic and Evolutionary Microbiology.   view more (2008-03-10)

Biodiversity and resilience of coral reefs
With over 3000 fish species, Indo-Pacific coral reefs represent one of the most diverse ecosystems on the globe. It is easy to assume that the loss of one or two species from these systems would have little impact. However, in an article in the April issue of Ecology Letters, Bellwood and... view more (2003-04-08)

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)

More Evidence Chicxulub Was Too Early
A new study of melted rock ejected far from the Yucatan's Chicxulub impact crater bolsters the idea that the famed impact was too early to have caused the mass extinction that killed the dinosaurs 65 million years ago.   view more (2006-03-30)

Study shows big game hunters, not climate change, killed off sloths
Prehistoric big game hunters and not the last ice age are the likely culprits in the extinction of giant ground sloths and other North American great mammals such as mammoths, mastodons and saber-toothed tigers, says a University of Florida researcher.   view more (2005-08-04)

New evidence implicates humans in prehistoric animal extinctions
Research led by UK and Australian scientists sheds new light on the role that our ancestors played in the extinction of Australia's prehistoric animals. The study, published this week in the journal Proceedings of the National Academy of Sciences of the USA, provides the first evidence that... view more (2008-08-12)

Butterfly fish 'may face extinction'
A beautiful black, white and yellow butterflyfish, much admired by eco-tourists, divers and aquarium keepers alike, may be at risk of extinction, scientists have warned.   view more (2008-02-25)

Lemurs' fur color may not define species
Different coat colour might not correspond to different species for nocturnal lemurs. In a study published today in the open access journal BMC Evolutionary Biology, researchers find that lemurs that appeared to belong to different species because they have strikingly different coat colours, are in... view more (2006-11-16)

Parasites a key to the decline of red colobus monkeys in forest fragments
Forest fragmentation threatens biodiversity, often causing declines or local extinctions in a majority of species while enhancing the prospects of a few.   view more (2007-10-25)
