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 population growth are rarely perfect, but are... 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)
Getting on 'the GABA receptor shuttle' to treat anxiety disorders
There are increasingly precise molecular insights into ways that stress exposure leads to fear and through which fear extinction resolves these fear states. view more (2009-10-22)
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 hermaphrodites have been selected in regions with frequent... view more...

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)
MU Researchers Use Computational Models to Study Fear
The brain is a complex system made of billions of neurons and thousands of connections that relate to every human feeling, including one of the strongest emotions, fear. view more (2009-10-01)
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 Cyclamen will become increasingly rare and might have... view more...

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 estimated the risk of their extinction by 2030 based... 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 and lake life today (9 Sept) at a special seminar... view more...

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 1,117 individuals, according to a study released in... view more... (2008-07-29)
Study unravels why certain fishes went extinct 65 million years ago
Large size and a fast bite spelled doom for bony fishes during the last mass extinction 65 million years ago, according to a new study to be published March 31, 2009, in the Proceedings of the National Academy of Sciences. view more (2009-03-27)
Conservation targets too small to stop extinction
Conservation biologists are setting their minimum population size targets too low to prevent extinction. view more (2009-10-14)
Evidence of the 'Lost World' -- did dinosaurs survive the end Cretaceous extinctions?
The Lost World, Sir Arthur Conan Doyle's account of an isolated community of dinosaurs that survived the catastrophic extinction event 65 million years ago, has no less appeal now than it did when it was written a century ago. view more (2009-04-28)
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)
Mammals that hibernate or burrow less likely to go extinct
The best way to survive the ill-effects of climate change and pollution may be to simply sleep through it. view more (2009-01-29)
