- Rare Marine Life
- Distinctive Mammals
Island ecosystems are particularly vulnerable and possess unique characteristics that make them critical to global biodiversity.
-
Endemic Plant Species: Endemic plant species refer to plants that grow naturally only in a specific geographical area, such as an island. Islands often host a variety of endemic flora, thanks to isolated evolutionary processes. For example, the Hawaiian Islands have over 1,000 species of native plants. According to the United States Geological Survey (USGS), about 90% of Hawaii’s native plant species are found nowhere else on Earth.
-
Unique Bird Species: Unique bird species are often found on islands due to habitat isolation. Islands act as breeding grounds for many bird species that evolve separately from mainland birds. The Flightless Kiwi of New Zealand is a prime example, representing unique adaptations to island life. The IUCN states that about 30% of the world’s birds are endemic to islands.
-
Rare Marine Life: Rare marine life refers to aquatic species that are highly localized, often found only in the waters spanning around islands. The Galápagos Islands are known for their extraordinary marine biodiversity, including the unique marine iguana. Research published in the Marine Biology journal highlights that the Galápagos marine reserve hosts numerous species, with many being endemic, showcasing the islands’ role in conservation.
-
Distinctive Mammals: Distinctive mammals include species that have uniquely adapted to island life, often due to lack of competition and predators. The Solenodon of Hispaniola is an example of a primitive mammal considered a living fossil. According to a study by the American Museum of Natural History, island mammals have evolved in isolation, leading to distinct traits.
In summary, islands support unique ecosystems characterized by endemic flora and fauna due to geographical isolation and specific environmental conditions.
