Mammoths were one of the "megafauna" that went extinct during the Pleistocene extinction. According to the first study of mammal range and diversity in "deep time" from the Eocene to the Pleistocene, the mammoth family did not show any sign of being predisposed for extinction.

Scientists have uncovered a lot about the Earth's greatest extinction event that took place 250 million years ago when rapid climate change wiped out nearly all marine species and a majority of those on land. Now, they have discovered a new culprit likely involved in the annihilation: an influx of mercury into the eco-system.

Predictions of the loss of animal and plant diversity around the world are common under models of future climate change. But a new study shows that because these climate models don't account for species competition and movement, they could grossly underestimate future extinctions.

Both climate change and humans were responsible for the extinction of some large mammals, like the musk ox in this photo, according to research that is the first of its kind to use genetic, archeological, and climatic data together to infer the population history of large Ice-Age mammals. The large international team's research, which will be published in the journal Nature, is expected to shed light on the possible fates of living species of mammals as our planet continues its current warming cycle.

Up to 45 rare species of wallaby, bandicoot and other Australian animals could become extinct within 20 years unless urgent action is taken to control introduced predators and other threats, scientists warned Wednesday.

A study recently released by a team from Northwestern University and the University of Arizona shows that religion and religious affiliations may be on the verge of extinction in the nine countries studied. Utilizing a mathematical model of nonlinear dynamics, the team analyzed data from censuses taken in nine different countries dating as far back as a century.

For more than 40 years, the International Union for Conservation of Nature (IUCN) has published the Red List of Threatened Species describing the conservation status of various species of animals. They are now also including plants in their lists and the picture they present is dramatic. According to recent estimates, around 20 per cent of flowering plants are currently at risk of extinction - though the exact number is unknown since such a small proportion of plant species has even been measured.

Does climate change seriously threaten to wipe out the human species if left unchecked? Examining our evolutionary past suggests it might once have been the perfect catalyst for our extinction. But now?

Pollution and global warming are pushing the world's oceans to the brink of a mass extinction of marine life unseen for tens of millions of years, a consortium of scientists warned Monday.

Metazoan-dominated reefs only took 1.5 million years to recover after the largest species extinction 252 million years ago, an international research team including paleontologists from the University of Zurich has established based on fossils from the Southwestern USA.

Scientists studying the fossils of tiny ocean-dwelling plankton, called foraminifera, have uncovered another piece in the puzzle of why species evolve or become extinct.

One in 10 species could face extinction by the year 2100 if current climate change impacts continue. This is the result of University of Exeter research, examining studies on the effects of recent climate change on plant and animal species and comparing this with predictions of future declines.

panel of marine scientists who met earlier this year in Oxford, England, have concluded that the world's oceans are facing an unprecedented loss of species. As the London Independent reports today, "The seas are degenerating far faster than anyone has predicted, the report says, because of the cumulative impact of a number of severe individual stresses, ranging from climate warming and sea-water acidification, to widespread chemical pollution and gross overfishing." They concluded that the negative impacts are greater than predicted, and that mass extinctions could occur within one human generation.

When the Earth's carbon dioxide level increased at a rapid rate during the Triassic-Jurassic period 200 million years ago, nearly half the ocean's marine life became extinct. USC Dornsife geologists contributed to a recent paper that examines materials embedded in ancient rocks to provide clues about the possibility of similar future global events.

"Many species of fruit fly lack the ability to adapt effectively to predicted increases in global temperatures and may face extinction in the near future, according to new research."

As global temperatures rise and climatic zones move polewards, species will need to find different environments to prevent extinction. New research, published today in the journal Molecular Ecology, has revealed that climate change is causing certain species to move and adapt to a range of new habitats.

Past waves of extinctions which removed some of the world's largest animals were caused by both people and climate change, according to new research from the University of Cambridge. Their findings were reported today, 05 March, in the journal Proceedings of the National Academy of Sciences (PNAS).

Conservationists may need to change their approach to protecting animals and plants from extinction if they are to successfully shield key species and habitats from the effects of global climate change, according to a new review in the journal Science.

The "colour" of our environment is becoming "bluer", a change that could have important implications for animals' risk of becoming extinct, ecologists have found. In a major study involving thousands of data points and published this week in the British Ecological Society's Journal of Animal Ecology, researchers examined how quickly or slowly animal populations and their environment change over time, something ecologists describe using "spectral colour".

The old saying there's plenty more fish in the sea might soon no longer apply to the Mediterranean, says Swiss-based International Union for Conservation of Nature. A study it is releasing Tuesday, April 19, 2011 says more than 40 species of marine fish there could soon disappear - almost half the species of sharks and rays and at least 12 species of bony fish are threatened with extinction due to overfishing, pollution and loss of habitat.
