In an effort to save the Snow Leopard, several wild and zoo examples are released in Antarctica. Does this work?
No, they wouln't survive. Antarctica is a lot more hostile than the Eurasian homeland of the snow leopard. You can't just take an animal and ship it out to a foreign environment and expect it to survive, even if they both have snow. I would guess that snow leopards would be able to easily eat penguins while the penguins are stuck in their rookeries but that would be about the only food source the snow leopards will have. They are not aquatic so they won't be able to predate most of the Antarctic wildlife which is marine based. What do the snow leopards live on when the penguins are off fishing, which is a significant part of the year when they are not forming breeding colonies?
Hopefully not, because the only way that they could survive is by wreaking havoc on the native animals of the Antarctic; just imagine the impact of leopards locating an emperor penguin colony just prior to the commencement of winter.Does this work?
Don't forget the Amur Leopard, it's more threatened than both of them, and Amur Leopards and Siberian Tigers are used to live in the same places, and used to rivalry with each other and with wolves and bears over prey.Instead of Antarctica, why not transplant Siberian tigers and snow leopards in the Alaskan/Canadian Arctic, say around the Yukon?
The flora and fauna wouldn't be as much of a shock, there'd be richer biomes to work with as Antarctica's basically a frozen desert.
