As the area of sampling A increases in an ecologically uniform area, the number of plant and animal species s increases in an approximately logarithmic manner, or s e bA", (1) where k < 1, as shown most recently in in the detailed analysis of Preston (1962). The same relationship holds for islands, where, as one of us has noted (Wilson, 1961), the parametersb and k vary among taxa. Thus, in the ponerine ants of Mela- nesia and the Moluccas, k (which might be called the faunal coefficient) is ap- proximately 0.5 where area is measured in square miles; in the Carabidae and her- petofauna of the Greater Antilles and as- sociated islands, 0.3; in the land and freshwater birds of Indonesia, 0.4; and in the islands of the Sahul Shelf (New Guinea and environs), 0.5. |
