The most obvious change associated with the termination of an ice age is the increase in temperature. Between 15,000 BP and 10,000 BP, a 6 °C increase in global mean annual temperatures occurred. This was generally thought to be the cause of the extinctions.
This is a list of Ice Age species preserved as permafrost mummies. It includes all known species that have had their tissues partially preserved within the permafrost layer of the Arctic and Subarctic. Most went extinct during the Late Pleistocene extinctions while some are still extant today. They have been listed to the most specific known ...
At the close of the Ice Age, with the loss of cold and dry conditions and the extinction of much of its prey, the Beringian wolf became extinct. The extinction of its prey has been attributed to the impact of climate change , competition with other species, including humans, or a combination of both factors.
The Ice Age reached its peak during the Last Glacial Maximum, when ice sheets commenced advancing from 33,000 years BP and reached their maximum positions 26,500 years BP. Deglaciation commenced in the Northern Hemisphere approximately 19,000 years BP, and in Antarctica approximately 14,500 years BC, which is consistent with evidence that this ...
Arctodus is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.5 Mya until 12,800 years ago). There are two recognized species: the lesser short-faced bear (Arctodus pristinus) and the giant short-faced bear (Arctodus simus).
Other possible prey species were giant deer, red deer, muskox, aurochs, wisent, steppe bison, and young woolly rhinoceros. It likely competed for prey with the European leopards , cave hyenas, brown bears and grey wolves in Eurasia, [ 62 ] along with short-faced bears , Homotherium , and Beringian wolves in Beringia .
Estimates of Wilson's Phalarope numbers are several thousand, and the birds can be seen in areas of water both large and small. You might get dizzy just watching!" These birds create whirlpools by ...
The predominant prey were water birds, mostly snatched directly from surface of the water and largely weighing 400 to 800 g (0.88 to 1.76 lb), i.e. buffleheads (at 24% by number and 17.4% by biomass of foods) and horned grebes (Podiceps auritus) (at 34.9% by number and 24.6% by biomass), followed by variously other water birds, often the ...
