Question

You hear rumors about an unusual series of four islands in the Tierra del Fuego archipelago of Chile. On these islands, the typical laws of island biogeography theory are reversed such that species colonization rates are influenced by island size, not isolation, and small islands have higher colonization rates than larger islands. In addition, islands close to the mainland have higher extinction rates than islands far from the mainland. Of the four islands in this archipelago, a _____ island _____ the mainland would have the SECOND LOWEST equilibrium number of species.

Answer 1

Of the four islands in this archipelago, a SMALL island CLOSE TO the mainland would have the SECOND LOWEST equilibrium number of species. Biogeography studies species distribution.

Biogeography refers to the discipline that examines the range of distribution of species and taxonomic groups in a given geographical area over geological time.

The theory of island biogeography is a scientific theory that posits the idea that larger islands exhibit a greater amount of species (i.e., higher biodiversity) than smaller islands.

According to this theory (island biogeography), each island represents a particular unique ecosystem, which is different from other surrounding ecosystems.
