  • Green Deserts

    When a habitat looks lush but is actually devoid of much of its native wildlife, it is sometimes called a green desert. A green desert might refer to a field planted with a single crop (called “monoculture”) or a forest planted with just one or several tree species.

  • Seed Dispersers

    Plants can’t move on their own, so they usually need a little help to spread their seeds far and wide. Animals that scatter these seeds — often by eating the fruit and pooping out the remains — are known as seed dispersers.

  • Hawaiian Honeycreepers

    Hawaiian honeycreepers are a group of songbirds endemic to the Hawaiian islands, all descended from a single species that arrived from the mainland six to seven million years ago. They are considered a dramatic example of adaptive radiation, a phenomenon in which a single species rapidly diversifies into many different ones. At one point, there…

  • Avian Malaria

    One of the major threats to Hawaiian honeycreepers is a deadly, mosquito-borne disease called avian malaria. Similar to malaria that infects humans, the disease is caused by parasites that enter honeycreepers’ bloodstreams when they are bitten by a disease-carrying mosquito.

  • Endemic Species

    When a species has a native range that is confined to an isolated patch of land or body of water, it is known as an endemic species.

  • Adaptive Radiation

    When a single ancestor species rapidly evolves into many different, specialized species, this is known as adaptive radiation.
