Deep freeze dealt death knell to bison (Ice Age)
CBC News Online ^ | 11/25/2004

Posted on 11/25/2004 7:25:47 PM PST by Fatalis

WASHINGTON - Hunters may not be to blame for the decline in bison populations, according to a new study that points the finger at climate change.

Scientists had thought bison were hunted to the brink of extinction when people first crossed an ice-free bridge between what's now Alaska and Siberia.

Two subspecies of bison now live in North America.

Now researchers say bison DNA shows their genetic diversity began to decline more than 20,000 years before humans reached eastern Beringia in what is now North America, according to archeological evidence.

Scientists at Oxford University analysed DNA samples from 442 fossils from bison that lived in what's now Alaska, Canada, China and Siberia.

The team of 27 scientists said the decline in bison diversity coincided with a deep freeze that may have done in many of the animals about 32,000 to 42,000 years ago.

The results suggest the two subspecies of bison ranging across North America today, the plains and the wood bison, are likely descendents of one population that migrated south before the deep freeze.

Cold "and arid conditions increasingly dominated, and some component of these ecological changes may have been sufficient to stress bison populations across Beringia," the study's authors wrote in Friday's issue of the journal Science.

Brown bears and a type of horse went extinct in Alaska at about the same time.

The researchers say their results point to climate as the main cause of decline for bison, rather than the final blow they faced.

And, to think, all this time I thought it was the fault of Republicans.

If this had not happened would Buffalo be the choice of Thanksgiving dinners instead of that smelly bird we consumed today...

Thanks for the ping. I never thought it was due to humans...there weren't enough. I have toyed with the idea that it could have been a virus/germ brought in by the humans though.

"If this had not happened would Buffalo be the choice of Thanksgiving dinners instead of that smelly bird we consumed today..."

The bird...turkey. Was one of the two animals domesticated in South America by the Natives...also, Guinna(sp) pigs.

The Spanish took the domesticated turkey back to Europe in the 1500's and the original Pilgrims to the new world brought it back to North America when they came. These domesticated turkeys brought by the Pilgrims eventually mixed with all the wild turkeys in North America. The turkey you ate today had genes brought here by the Pilgrims.

The story of the Indians introducing the turkey to the Pilgrims is just BS!

"the brown bear extinction referred to may be (probably) the short-faced bear, which (if it were around) would make the grizzly run for its mommy. :') "

I think so.

At the end of the last Ice Age (just yesterday in geological time), camels, bisons, mammoths, lions, saber-toothed cats, and packs of wolves roamed the Los Angeles Basin. Had we lived here then, we also would have shared territory with the short-faced bear, Arctodus simus, perhaps the largest and most powerful predator in North America at the time. When fully grown, the male of this snub-nosed, long-legged carnivore was immense, as much as 2 feet taller at the shoulder than the largest grizzly or polar bear and-- at 1,500 to 1,800 pounds-at least 500 pounds heavier than the modern species.

There were absolutely no emission controls on the cars, back then.

Ive read stories about the "God bears of Kamchatka" and somewhere along the line I saw a show in search of them. The "jist" of it is that some believe that a rare Arctodus simus still exists here and there generally unnoticed amongst the other brown bears of Kamchatka.

80 million Buffalo have disappeared since the "White" man came to North America. 100 million Beef Cattle have taken their place. Why? Beef taste better!

It was because all those mean-spirited human hunters were Republicans - and never bothered to go see the "Day After Yesterday", down at the CaveCity Performance Art Theatre.

I read that the Great Plains was once forested but the Indians burned it so often chasing game that it couldn't re-grow.

Do you have any idea how hard it would be to deep fry a buffalo?

BTW - The difference between a buffalo and a bison is that you can't wash your face in a buffalo.

Of course the cost would be offset by the gallons and gallons of Bio Fuel converted from the cooking oil for your Monster Truck. Also the Bison excrement could be used to keep your wig-warm...

I really hate the title of this article..

One would think the Bison is extinct, and somehow, it was the fault of the Ice Age..

Quite to the contrary, the Bison was doing quite well when european colonists reached american shores..
In fact, early americans documented complaints of bison as far east as New York, and having their buildings knocked down by bison that were attempting to "get rid of an itch"..
The bison is (was) not just a plains critter..
They also populated forested areas, and were wide-spread across the continent.. ( although they probably didn't do too well in desert areas of the southwest, they were also there, in smaller numbers.. )

The position that the Ice Age created a "decline" in the population is basically true, but hardly monumental news..
A great deal of the animal's grazing range was covered in ice.. the resultant reduction in grazing further resulted in a reduction in population..

The article is interesting in that it uses DNA testing to document "which" bison strains survived to the present, but actually, IMHO, really doesn't advance science by reaching conclusions as stated in the title..

Maybe this brief description of two short-faced bear species would be of interest.

They still do, plus some variants of hippos, RINO's DemoncRATs, and of course the Glutenous Michaelis Mooreass.

I beg to differ. Buffalo meat is, on the whole, better tasting and healthier than cattle beef.

The reason we keep cattle is because they've been bred for docility for millenia. Buffalo are more much more aggresive and prone to violence.
