    Biota Behaving Badly

    Members of an established ecosystem develop a sense of balance, usually permitting at least limited biodiversity and a stable structure. When interlopers arrive that aren’t responsive to the same environmental checks and balances, they can overrun the ecosystem, eliminating some members and quickly dominating others.
