Novel Hawaiian communities operate similarly to native ecosystems

Red-billed Leiothrix, Leiothrix lutea, sometimes known to aviculturists as the Pekin Robin or as the Pekin Nightingale, is one of many non-native species that can be found on the Hawaiian Isles. Native to lowland forests of India, Bhutan, Nepal, Burma and parts of Tibet, it was introduced to Hawai'i in 1918, and subsequently spread throughout all the islands except Lanai.

In Hawaii's novel seed dispersal networks, introduced birds primarily disperse introduced plants. In a new study published in Science, research shows these novel networks operate very similarly to native communities worldwide.
