Well, when continental species get introduced to islands, it's sayonara
locals 9 times out of 10, and sometimes very quickly. Earth has an
enormous biosphere and bacteria at least swap genes with avidity.
I doubt Europa can match that, assuming it has any life at all, simply
as there's far less usable energy there.
