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)

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)

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)

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

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)

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)

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)

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)

All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon... view more (2003-05-22)

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)

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)

Scientists warn that species extinction could reduce productivity of plants on Earth by half
An international team of scientists has published a new analysis showing that as plant species around the world go extinct, natural habitats become less productive and contain fewer total plants -- a situation that could ultimately compromise important benefits that humans get from nature.   view more (2007-11-06)

NOAA proposes federal regulations to protect black abalone
NOAA Fisheries Service published with the Federal Register today a proposed rule to list black abalone, a marine mollusk coveted by fishermen and gourmets alike, as endangered under the Endangered Species Act (ESA).   view more (2008-01-14)

Extinction most likely for rare trees in the Amazon rainforest
Common tree species in the Amazon will survive even grim scenarios of deforestation and road-building, but rare trees could suffer extinction rates of up to 50 percent, predict Smithsonian scientists and colleagues in the Aug. 12 issue of the journal Proceedings of the National Academy of Science.    view more (2008-08-14)

Avian Persistence in Fragmented Rainforest
Loss and deterioraton of indigenous habitat increasingly affect natural populations worldwide. As a result of these processes, new selection pressures are imposed upon organisms, increasing local extinction rates. Simultaneously, reduced movement among remnant patches lowers colonisation rates and... view more (2002-11-08)

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)

Current mass extinction spurs major study of which plants to save
The Earth is in the midst of the sixth mass extinction of both plants and animals, with nearly 50 percent of all species disappearing, scientists say.   view more (2008-10-21)

Priority regions for threatened frog and toad conservation in Latin America
Nearly 35% of all amphibians are now threatened of extinction raising them to the position of the most endangered group of animals in the world.   view more (2008-05-07)

Reproductive speed protects large animals from being hunted to extinction
The slower their reproductive cycle, the higher the risk of extinction for large grazing animals such as deer and antelope that are hunted by humans.   view more (2007-05-16)

Extinction
Two teams of British scientists have produced the best evidence yet that our planet is experiencing a mass extinction. Two separate papers, published in Science 19 March and funded largely by the Natural Environment Research Council (NERC) highlight the serious concerns that have been growing among... view more (2004-03-18)

Climate change isolates Rocky Mountain butterflies
Expanding forests in the Canadian Rocky Mountains are slowly isolating groups of alpine butterflies from each other, which may lead to the extinction of the colourful insects in some areas, says a new study from the University of Alberta.   view more (2007-08-14)

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)
