Saber-tooth Cats In The Late Pleistocene May Not Have Starved
2012-12-27 06:30:23

April Flowers for redOrbit.com - Your Universe Online A new study, led by Vanderbilt University, reveals that American lions and saber-toothed cats that roamed the North American continent in the last Pleistocene were living well off the fat of the land. The results of this study, published in PLOS ONE, were gathered from microscopic wear patterns on the teeth of these great cats recovered from the La Brea Tar Pits in southern California. The study, contrary to prior analysis, did not...

Birds In New Zealand Face Extinction
2012-08-05 19:50:05

redOrbit Staff & Wire Reports - Your Universe Online Keys to survival today differ from those of the past. This is revealed in a new study of nearly 300 species of New Zealand birds – from pre-human times to the present. Lead author Lindell Bromham of Australian National University said, "Taking into consideration the growing number of studies that try to predict which species could be lost in the future based on what kinds of species are considered most threatened today the...

Climate Change Linked To Woolly Mammoth Decline
2012-06-14 08:29:59

Brett Smith for redOrbit.com New evidence points to a dual conspiracy of climate change factors and hunting activities by early man that to drove the woolly mammoth to extinction between 4,000 and 10,000 years ago. The gradual decline of the sub-Arctic giant was likely caused in part by global warming induced changes in habitat, according to a new report published by an American-led research team in Nature Communications this week. These changes included a decline in the mammoths' food...

Although humans and woolly mammoths co-existed for millennia, the shaggy giants disappeared from the globe between 4,000 and 10,000 years ago, and scientists couldn't explain until recently exactly how the Flinstonian behemoths went extinct. In a paper published June 12 in the journal Nature Communications, UCLA researchers and colleagues reveal that not long after the last ice age, the last woolly mammoths succumbed to a lethal combination of climate warming, encroaching humans and...

Mammal Diversity Aided In Survival Over Deep Time
2012-04-24 12:24:49

Lawrence LeBlond for RedOrbit.com In a first of its kind study, researchers from Vanderbilt University found that mammals´ best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes. Larisa R. G. DeSantis, Assistant Professor of Earth and Environmental Sciences at Vanderbilt, led researchers in studying how North American mammals adapted to climate change over a 56-million-year...

Caltech researchers say habitat loss and tropical cooling were to blame for mass extinction The second-largest mass extinction in Earth's history coincided with a short but intense ice age during which enormous glaciers grew and sea levels dropped. Although it has long been agreed that the so-called Late Ordovician mass extinction–which occurred about 450 million years ago–was related to climate change, exactly how the climate change produced the extinction has not been known....

Demise Of Larger Prehistoric Animals Blamed On Climate Change, Humankind
2012-03-06 09:05:44

The death and extinction of many large, prehistoric animals may be due largely in part to man´s actions as well as climate change. The University of Cambridge has conducted new research to determine if humankind played a significant role in the destruction of these prehistoric megafauna. The findings were posted on March 5, 2012 in the journal PNAS. The research team examined extinctions during the late Quaternary period (700,000 years ago to present day) but focused much of their...

Study Finds Culprits To Ice Age Mammal Extinctions
2011-11-02 13:30:15

A research team involving over 40 academic institutions around the world is trying to tackle the question of what caused extinctions in the Ice Age. The study found that the extinction of mammals like the woolly rhinoceros and woolly mammoth was not due to humans or climate change.  The team found using ancient megafauna DNA, climate data and the archeological record that humans played no part in the extinction of the wooly rhino or the musk ox in Eurasia.  The researchers...

An international team of scientists have discovered that climate change played a major role in causing mass extinction of mammals in the late quaternary era, 50,000 years ago. Their study, published in Evolution, takes a new approach to this hotly debated topic by using global data modeling to build continental "Ëœclimate footprints.' "Between 50,000 and 3,000 years before present (BP) 65% of mammal species weighing over 44kg went extinct, together with a lower proportion of small...

Did a change in climate or an extraterrestrial impact bring an end to the beasts and people that roamed the Southwest shortly after the last ice age? A team of researchers from the University of Arizona has revisited evidence pointing to a cataclysmic event thought by many scientists to have wiped out the North American megafauna "“ such as mammoths, saber tooth cats, giant ground sloths and Dire wolves "“ along with the Clovis hunter-gatherer culture some 13,000 years ago. The...

Panthera leo spelaea
2012-11-16 15:34:04

Commonly known as the Eurasian cave lion or the European cave lion, Panthera leo spelaea is an extinct subspecies of lion. It is thought to have lived during the Pleistocene epoch, and may have lived in the Balkans in southeastern Europe until 2,000 years ago. The range of this cave lion would have included northwestern North America, Asia, and areas of Europe and would have extended from Germany, Spain, and Great Britain to the Yukon Territory. Its range also extended from Turkistan to...
