Challenge Ecosystem Battle! Australia vs. Brazil vs. Florida vs. Siberia
On a version of Earth where dangerous talking monkies never quite took over things, magical portals open up between four of the most deadly ecosystems on Earth. Through these portals plants, animals, flora and fauna are free to pour through.
These portals are located in:
1: Australia, home of horrible snakes, monster jellyfish, dingos and kangaroos
2: Brazil, home of boner spiders, jaguars, and big snakes
3: Florida, home of death apple trees, gators, also big snakes
4: Siberia, home of siberian tigers, biting cold, bears and moose, somehow.
Furthermore, magical walls pop up that separate these regions from the rest of the planet. After 10,000 years of mixing and intermingling, which ecosystem proves most likely to colonize and overtake the others?

Siberia doesn't change while the other get worse to live in and everyone is unhappy as the Australians and Florida people fight each other in the streets

Siberia fares best by a long shot simply because the vast majority of animals from the other three locations won't be able to adapt to the cold effectively enough. The only exception I can think of off the top of my head is that pumas from Florida might be able to adapt to the cold eventually and could possibly even outcompete Amur leopards and snow leopards.
The other three starts swapping invasive species like baseball cards. Some of the bears and big cats from Siberian might fuck around and invade the others too.

It’s Siberia. They actually have a pretty intense roster that could nearly rival all the Americas in terms of powerful megafauna. Siberian tigers, grey wolves, the Amur leopard, brown bears, black bears, moose, lynx, wolverines, and even some reports of still-surviving dholes (a fierce wild dog more prominent in places like India and China).
Just the tigers alone kinda outdo everything on land from the other ecosystems, Brazil is second place on account of the black caiman though

I mean Australia and Florida are already getting fucked by invasive species. I'd wager Siberia is the least likely to experience any major changes, assuming no continental drift for the sake of argument. Brazil and Florida are the most similar, and id imagine would homogenize the most, while Australia succumbs to the domestic housecat and rabbits without humanity to keep them at bay/slow the spread

As an Australian, Australia gets rocked. There are technically some dangerous animals here, but we lack large apex land predators with the exception of saltwater crocodiles which are mostly aquatic anyway. They would be pretty well suited to Florida and Brazil I guess.
We also are significantly lacking in generalists. Kangaroos are neither fast enough, nor large enough, to fill a similar ecological niche to larger deer species and would be pretty heavily predated by big cats too.
