There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

My guess would be bison (bigger than moose) though I suppose its possible a brown bear some time somewhere has killed a large marine mammal in the same way polar bears do beluga whales.

Do you think a Polar Bear could survive on an almost entirely herbivorous diet like Brown Bears?

I doubt it

I remember I read somewhere that Polar Bears and Brown Bears are extremely closely related. As far as I remember, they produce healthy and fertile offspring unlike all the big cat hybrids who have so many health problems and usually are infertile.

If they are still so closely related, it could make sense that Polar Bears still have a similar digestive tract like Brown Bears and so it may allow Polar Bears to live on a purely herbivorous diet just like Brown Bears live.

Competitive exclusion principle dictates they cant occupy the same niche as brown bears without one being extirpated, and with brown bears being more suited to gaining nutrients from vegetation (and needing less to survive) my guess would be polar bears lose out. They would have to still supplement much of their diet with meat, and inland this would be carrion as hunting prey like caribou seems unlikely. It could happen, and polar bears have survived warm periods before, but I would not expect them to become totally brown bear like in their ecology.
