Question:
When a new species is introduced into an ecosystem and it competes for food with the natives species, causing problems, what is this called?

Replies:
I'm not sure there is a technical term, most naturalists and land managers refer to such introduced species as "invasives."

J. Elliott

The term most used is "nonindigenous invasive species" when referring to species that have invaded an ecosystem.
