I was speaking from a contemporary perspective, Manuel. From a very long
term perspective perhaps we can say that a species that somehow translocated
into another ecosystem may have initially disrupted that ecosystem but after
a few thousand generations the species and the ecosystem evolved

I would argue that Mr. Cruzan misses a big point that WT points to. Species do
expand their ranges, yes. BUT, they will only do so into conditions that favor
them. Sure, speciation will create others. But,

What is NATURAL?
In environmental science no one talks about NATURAL.
You have impaired, unimpaired, and degrees of impairment because that
has a meaning.
Natural is too nebulous and subjective.
