摘要

The theory of island biogeography of MacArthur and Wilson (1967) represents a first attempt at developing a unifying concept for bio- diversity research across islands and fragmented biomes. It uses two physical parameters, distance (or isolation) and size of area to de- fine species equilibria. This contribution expands on the theory by adding a third phyical parameter, elevation (or topography), to fo- cus on biodiversity relationships. This third parameter allows island ecosystems to be connected horizontally across Pacific-wide biomes.
