““Invasive species are often thought of as species that take over wherever they get in,” says Jake Vander Zanden, a UW limnology professor who directed the research. “But, in our experience studying lakes and rivers, in most places they weren’t all that abundant. It was only in a few places where they got out of hand.” If that pattern held true, the researchers realized, then invasives were acting a lot like their native counterparts.”
A species place of origin does not determine whether if it is inherently nefarious in a new area.
