ERT-2.E—Describe the role of island biogeography in evolution

Describe the role of island biogeography in evolution.

• Many island species have evolved to be specialists versus generalists because of the limited resources, such as food and territory, on most islands. The long-term survival of specialists may be jeopardized if and when invasive species, typically generalists, are introduced and outcompete the specialists.
• Enduring understanding ERT-2: Ecosystems have structure and diversity that change over time.
