Geographic Ecology

Chapter Objectives


On islands and habitat fragments on continents, species richness increases with area and decreases with isolation.

Species richness on islands can be modeled as a dynamic balance between immigration and extinction of species.

Species richness generally increases from middle and high latitudes to the equator.

Long-term historical and regional processes significantly influence the structure of biotas and ecosystems.
