Hippos going native in South America filling the ecological niche left by extinct native animals.

TIL that there was once such a thing as a 3-ton wombat.

The Google search results are pretty terrifying.

There's a Tim Flannery book about the ecological history of Australia (the title of which I can't remember off the top of my head) and I know it suggested bringing Komodo dragons into the top end of Aus as a replacement for the mega-lizards that used to live in the area. One thing I never considered was the importance of the poo. He made quite a compelling case (at least when I was reading it) that the loss of dung and associated dung beetles and other dung-using animals incorporating it into the top soil was at least partly responsible for its degradation and subsequent loss.

It seems to be a common understanding that the extinction of the South American Megatherium (and other giant ground sloths) was disastrous to the propagation of the Avocado, as it was the only animal that was able to distribute the Avocado seed, nothing else having a gut large enough to swallow the seed and pass it whole.
Had it not been for humans it would have been very sensitive to extinction by environment loss.

See Ben the Dung Beetle
from the series "Maya the Bee", episode "In Search of Lost Dung".

Plenty more on the 'net.
