Island biodiversity: Stable but vulnerable

Press/Media: ResearchAcademic

Description

The biodiversity on islands is the result of an equilibrium between the immigration of new species and the extinction of established ones. This idea was proposed exactly 50 years ago by the founders of Island Biogeography Theory, Robert H. MacArthur and Edward O. Wilson. But it had never been proven – until now that is. Ecologists from the Museum für Naturkunde in Berlin (Germany), Stony Brook University (USA) and the University of Groningen have discovered that the bat species on the Greater Antilles islands were in a state of equilibrium before humans arrived some 4000 years ago. Then extinctions became prevalent. The researchers calculated that it will take nature eight million years to restore the original diversity. The results were published in Nature Ecology & Evolution on 9 January.

    DescriptionMore than half of mammal species went extinct after human colonization in the Caribbean alone. Can nature restore the numbers of species on islands to levels that existed before human arrival—and, if so—how long would it take for nature to regain this lost mammal diversity?

    DescriptionFifty years ago MacArthur and Wilson predicted species diversity on islands would approach a dynamic equilibrium balancing colonization, and some speciation, against extinction. The long-term species diversity of Greater Antillean New World leaf-nosed bats and close relatives shows such an equilibrium, as well as how Holocene extinctions have dragged diversity far from it.
