Logic

The Argentine ant (Linepithema humile) is a common invasive species worldwide in regions with mediterranean or subtropical climates like much of California [1].

Can Argentine ants be meaningfully called both common worldwide and invasive? If it has already become common and well-established, what is it invading? Is it appropriate to assert that the species exists worldwide and then back off to specify Mediterranean or subtropical climates? Such enthusiastic but confused advocacy is endemic to invasion biology, but contributes nothing (at best) to the research findings.

Of course a species can be both common worldwide and invasive.
Invasiveness implies a certain type of behavior/strategy which can be viewed at multiple scales.
