Well, it is a bit like this:
If all the people in your street moved out and left the houses empty, some homeless people, or squatters might see those homes and take the opportunity to move in. They would be ‘an invasive species moving into a new open niche’, although I mean no offence to squatters or homeless people. The homeless people would be quite hardy and would probably adapt quite quickly to their new home, having not had one before, whereas other people who have a home already might think long and hard before they might move in to the empty homes, if ever. These would be less invasive, not so hardy species.
I hope you get the picture with this analogy. I am not sure that it is 100% correct, but it is sort of the idea. Some things in science are explained in a very odd way, when in fact, they can be just common sense if explained a different way.
