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)

Ancient DNA traces the woolly mammoth's disappearance
Some ancient-DNA evidence has offered new clues to a very cold case: the disappearance of the last woolly mammoths, one of the most iconic of all Ice Age giants, according to a June 7th report published online in Current Biology, a publication of Cell Press.   view more (2007-06-08)

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)

Global warming may not have ended Ice-Age, says research
Scientists at the University of Sheffield have used fossilised leaves to determine the effect of greenhouse gases on the end of the Ice Age 300m years ago, according to an article published in PNAS. The study, led by Professor David Beerling, examined fossilised leaves to determine how much carbon... view more (2002-09-12)

Ice Ages and rivers may have affected gorilla diversification
Geography and historical climate change may have both played a major role in gorilla evolutionary diversification, according to a new genetic study by Cardiff University and the University of New Orleans.   view more (2007-12-11)

In the Cornucopia of the European Project of Ice Coring in Antarctica: the oldest Antarctic ice core
On Tuesday 21th of December 2004 a European team involved in Epica (European Project for Ice Coring in Antarctica) reached the drilling depth of 3270.2, which is five meters above the bedrock at Dome C, on the central plateau of the east Antarctic ice sheet. The ice is melting at the bedrock and it... view more (2005-01-13)

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)

Remnants of ice age linger in gravity
Researchers have uncovered a large area of low but increasing gravity over North America - the lingering effect of the last ice age when sheets of ice sometimes three kilometres thick covered nearly all of Canada and the northeastern U.S.   view more (2007-05-11)

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... view more (2002-09-20)

Predetermined winners and losers in the Ice Age extinction game
The Quaternary ice ages caused severe decimation of the European tree flora. Of the diverse pre-Ice Age tree flora only a minority of the genera are still widespread in Europe. Most of the remainder have been lost altogether from the European flora and now only occurs in Asia and/or North America,... view more (2003-07-02)

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)

Where Does the North Pole Ice Come From? The Origin of the Northern Hemisphere Ice Age
Large areas of the Northern Hemisphere are currently covered with ice. This has, however, not always been the case. In the current issue of the science magazine "Nature", scientists from the GeoForschungsZentrum Potsdam (GFZ) and the Potsdam Institute for Climate Impact Research (PIK) present a... view more (2005-02-23)

Radar opens new window into the ice for Antarctic scientists
Scientists are getting their first glimpse into the inner secrets of an ice shelf, thanks to the innovative application of a new radar technique developed by British Antarctic Survey (BAS).   view more (2006-10-17)

How chilly was the last ice age?
Polar oceans permanently covered with ice, temperatures ten to twelve degrees Celsius lower than today in the North Atlantic region, tropical oceans on the other hand only two degrees Celsius below modern values: Until quite recently these were the general ideas climate researchers had about the... view more (1999-05-03)

Soviet plans implemented by Nature 90,000 years ago
One of the more controversial environmental issues, which emerged in the final years of the Soviet era, was the plan to dam and reverse the flow of north-flowing rivers in order to irrigate the dry southern steppes. This scheme was roundly criticised by scientists and environmentalists at the time... view more (2002-01-22)

Ice age imprint found on cod DNA
An international team of researchers, led by the University of Sheffield, has demonstrated how Atlantic cod responded to past natural climate extremes. The new research could help in determining cods vulnerability to future global warming.   view more (2007-11-14)

Ice sheets drive atmospheric carbon dioxide levels, inverting previous ice-age theory
In the early 20th century, Milutin Milankovitch, a leading astronomer and climatologist of the time, proposed that the Earth's ice-age cycles could be predicted because they correspond directly with routine changes in the Earth's orbit and its tilt over cycles of tens of thousands of years.   view more (2006-07-25)

Ancient engravings found in Somerset cave
Two members of the University of Bristol Spelaeological Society have discovered an engraving in a cave in the Mendip Hills, Somerset, which may be at least 10,000 years old.   view more (2005-02-07)

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)

UK Princess sees oldest ice on earth
Princess Anne, currently visiting Antarctica, was today given a gift of ice that is 50000 years old. It came from an ice core - a cylinder of ice drilled from the Antarctic ice sheet - drilled by the European Project for Ice Coring in Antarctica (EPICA). EPICA, a consortium of 10 European nations,... view more (2002-02-08)

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)

Climate Research: Oldest Ice in Process
Scientists at the Alfred Wegener Institute for Polar and Marine Research (AWI) are handling the oldest ice that has ever been unearthed: The ice cores, which were drilled during last winter in the Antarctic research station Dome C, are up to 900.000 years old. They come from a depth of 3200 metres... view more (2003-11-14)

Seafloor creatures destroyed by ice action during ice ages
The ice ages made massive changes to the Earth's landscape. But what was happening below the ice in the oceans?   view more (2005-10-18)

Giant project to test Antarctic ice stability
If rising global temperatures cause the ice streams of Western Antarctica to break up, major cities and agricultural heartlands the world over would be submerged. Researchers from the University of Leeds' School of Geography are set to embark on a £1m, three-year project to find out exactly... view more (2004-05-10)
