There are five variables to consider whenever thinking about the island biogeography theory. These include the immigration rates of new species, the emigration rates, the extinction rates, the size of the island, and the distance the island is to another land mass. The land mass could be a mainland or another island.
The two divisions of biogeography reflect these two ways that animals come to occupy an area. Biogeography can be broken down into historical biogeography, which studies the past history and evolution of a species, and ecological biogeography, which studies the environment of a species. Biomes are regions of distinct climate and plant life.

ISLAND BIOGEOGRAPHY AND EVOLUTION: SOLVING A PHYLOGENETIC PUZZLE WITH MOLECULAR GENETICS INTRODUCTION Ever since Charles Darwin formulated his hypothesis on how the finches of the Galapagos Islands evolved into 13 species, islands have been a prime target for the study of evolution. By their very nature, islands are isolated and are essentially ...
The surprise is that stehlini on Gran Canaria appears to have the oldest ancestor although atlantica is actually closer to Africa. It would be interesting to know more about the actual ocean currents affecting this island group. It could provide an answer to this unexpected surprise. Island Biogeography and Evolution:

Students will study the concept of speciation and predict an island habitat"s biodiversity based on the island's size and distance from the mainland.
Biogeography Definition. Biogeography refers to the distribution of various species and ecosystems geographically and throughout geological time and space. Biogeography is often studied in the context of ecological and historical factors which have shaped the geographical distribution of organisms over time.
