    Although he was conscious of the stability being replaced by resistance against invaders and the concept of the ecological niche, I believe his argument loses its influence by not centralizing on how we can make invasive species become less harmful in an ecosystem with no diversity rather then completely accepting the concept that invasion decreases when biodiversity increases. He claims that niches are empty when there’s fewer species and filled when there’s more species causing ecosystems with…

    result in two species sharing different parts of a niche”(pg.249).
