Improved estimates of population extinction risk (Harding and McNamara)
An important application of theoretical ecology is in estimation of species extinction risk. Extinction models guide the selection of management regimes for endangered species. Two vital parameters in these models are the mean population growth rate and its variance. However, empirical data on... view more (2003-12-10)

Picky eating potentially perilous for bats
Working in the Department of Ecology and Organismal Biology, Justin Boyles and Jonathan Storm examined the possibility of a link between dietary specialization and the risk of extinction for bats in Australia, Europe and North America.   view more (2007-07-25)

Hermaphroditic plants have genetic advantage in areas where extinctions are frequent
In one of the first studies to empirically compare the reproductive success of hermaphrodites and male and female populations, biologists from the University of Oxford make use of the rare and extreme sexual diversity displayed in a species of European weed to test the hypothesis that... view more (2006-02-22)

Mass extinction's cause: 'Sick Earth'
What really caused the largest mass extinction in Earth's history?   view more (2006-10-23)

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)

Improved predictions of warming-induced extinctions sought
In the March 2007 issue of BioScience, an international team of 19 researchers calls for better forecasting of the effects of global warming on extinction rates.   view more (2007-03-01)

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... view more (2006-09-20)

Extinction by asteroid a rarity
In geology as in cancer research, the silver bullet theory always gets the headlines and nearly always turns out to be wrong.   view more (2008-10-07)

Carnivore extinction risk determined more by biology than human population density, says study
Carnivores around the world are more at risk of extinction due to their own intrinsic biological attributes than from an increasing human population with whom they share their space, say scientists in a study published this week. Researchers looking at all 280 carnivore species around the world... view more (2004-07-15)

Media invitation - Environmental change in Antarctic lakes and seas: the chances for survival or extinction? BA Festival of Science, Univ of Leicester
The effects of the warming of the Earth`s climate on Antarctic lakes and seas is a matter of life or death for many plants and animals at the frozen continent. Professor Lloyd Peck, biologist with British Antarctic Survey (BAS) discusses the prospects for survival or extinction of Antarctic marine... view more (2002-09-05)

Newly discovered monkey is threatened with extinction
Just three years after it was discovered, a new species of monkey is threatened with extinction according to the Wildlife Conservation Society, which recently published the first-ever census of the endangered primate. Known as the "kipunji," the large, forest-dwelling primate hovers at... view more (2008-07-29)

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)

Madagascar`s lost wilderness @ the London `Catastrophes` conference
In the last 2000 years Madagascar has lost its entire endemic megafauna. This includes giant lemurs, pygmy hippos, elephant birds, and giant tortoises. This loss is the planet`s most recent prehistoric extinction event affecting a region with continental-scale diversity.   view more (2002-08-17)

Canada's shores saved animals from devastating climate change
The shorelines of ancient Alberta, British Columbia and the Canadian Arctic were an important refuge for some of the world's earliest animals, most of which were wiped out by a mysterious global extinction event some 252 million years ago.   view more (2008-10-01)

More than a meteor likely killed dinosaurs 65 million years ago
Growing evidence shows that the dinosaurs and their contemporaries were not wiped out by the famed Chicxulub meteor impact alone, according to a paleontologist who says multiple meteor impacts, massive volcanism in India and climate changes culminated in the end of the Cretaceous Period.   view more (2006-10-27)

Meteor no longer prime suspect in great extinction
The greatest mass extinction in Earth's history also may have been one of the slowest, according to a study that casts further doubt on the extinction-by-meteor theory.   view more (2007-10-25)

Recovering from a mass extinction
The full recovery of ecological systems, following the most devastating extinction event of all time, took at least 30 million years, according to new research from the University of Bristol.   view more (2008-01-21)

New theory for mass extinctions
A new theory on just what causes Earth's worst mass extinctions may help settle the endless scientific dust-up on the matter.   view more (2006-10-25)

Size matters: Preventing large mammal extinction
Saving large mammals such as elephants and rhino from extinction could be made more effective by focusing efforts on individual species as well as their habitats.   view more (2005-07-25)

Tomorrow's endangered species: Act now to protect species not yet under threat
Conservationists should be acting now to protect mammals such as North American reindeer which risk extinction in the future as the human population grows, according to research published today.   view more (2006-03-07)

First global bird map provides new clues to future extinctions
The first global survey of bird diversity could play a key role in identifying species most vulnerable to extinction, researchers report today in the journal PLoS Biology.   view more (2006-06-20)

Dinosaur Deaths Outsourced to India?
A series of monumental volcanic eruptions in India may have killed the dinosaurs 65 million years ago, not a meteor impact in the Gulf of Mexico.   view more (2007-10-31)

No safe ground for life to stand on during world's largest mass extinction
The world's largest mass extinction was probably caused by poisonous volcanic gas, according to research published today.   view more (2005-12-02)

Yale biologists 'trick' viruses into extinction
While human changes to the environment cause conservation biologists to worry about species extinction, Yale biologists are reversing the logic by trying to trap viruses in habitats that force their extinction, according to a report in Ecology Letters.   view more (2007-02-13)

Ebb and flow of the sea drives world's big extinction events
If you are curious about Earth's periodic mass extinction events such as the sudden demise of the dinosaurs 65 million years ago, you might consider crashing asteroids and sky-darkening super volcanoes as culprits.   view more (2008-06-16)
