Size comparisons

Now, a comparison of an Amur tiger and a Kodiak bear would be interesting to see...
@GBrotherbear:
The average Ussuri bear's weight would have decreased by 70 kilos since the seventies ? That's a lot ! I would have believed that bears, being omnivorous, could be more able (than tigers for example) to adapt to the human pressure and so on.

The reintroduction of wolves in Yellowstone proved to be more beneficial than harmful to the local grizzly bears. Less meat would likely produce smaller bears ( imo ). The charts have the Amur tiger, the American grizzly, and the Ussuri brown bear all at roughly the same weight ( 2011-2013 ) ... 193 kg = 425.5 pounds.
Competition with natural predators encourages the animals to be greater and stronger (the struggle for life implying the elimination of the weakest). In the contrary human pressure, the hunt of trophies, by eliminating the biggest males, the males having the biggest horns, the biggest tusks and so on, favours the least remarkable males, animals. Good demonstration by the example ! Sad for the Amour tiger and the Ussuri bear...
Basically, wherever humans go, natural selection seems to matter less and less, resulting in physically weaker species of animals.
This removal of natural selection is definitely apparent in our society. Weaker, most often richer, people have more access to healthcare and can often spread their weak genes around as a result. This is one reason why most of the human population has a extremely mutative allele of their genes, unlike any other animal, including the animals that inbreed. We constantly get exposed with hazardous chemicals and products, they've really ruined the human species.
Tigerluver; Your post on four of the biggest bears ever ( post #53 ) is really outstanding. I'd love to see a modern polar bear, Florida cave bear, European cave bear, and Agriotherium africanus... if possible. Thank you.
Please make home made size comparisons as well if you wish.

@Kingtheropod, here's the size comparison thread we have going for a while. I merged your last thread into here to keep it all as one for now.
On post #68, it appears that several could compete for the title of "Biggest Pachyderm Ever" considering that fossil finds are likely limited. Some of them dwarf our big modern elephants. Nice.

I found this random video of a White Rhino with Bison.
I'd assume thats a young male white Rhino judging from it's behavior but cool to see the large Bovine and Rhino Together.  (05-06-2016, 03:36 PM)brotherbear Wrote: Now, a comparison of an Amur tiger and a Kodiak bear would be interesting to see... Hello @

It is my understanding that a shoulder height of four and a half feet ( 1.37 m ) is pretty much average for a mature male. I will edit and add about 1.47 m for a massive individual.

EXPEDITION KODIAK Grizzly Bears on Kodiak Island, Alaska * For the last 10 thousand years, since the end of the last ice age, Kodiak Island has been isolated from the mainland by the 40-kilometre wide Shelikof Strait. * The brown bears on Kodiak Island evolved into their own unique subspecies. * Kodiak brown bears are the biggest bears on earth. * Kodiak Island is home to nearly thirty-five hundred bears. * Kodiak Island has the densest concentration of brown bears anywhere in the world, with just under one bear for every 2.6 square kilometres. * Bears in Yellowstone National Park can stand about 100 centimetres at the shoulder when on all fours and weigh about 275 kilograms. * Coastal brown bears can stand 112 centimetres tall at the shoulder when on all fours and weigh 410 kilograms or more. * A Kodiak bear can stand more than 140 centimetres tall at the shoulder when on all fours and weigh more than 630 kilos. |
