Native groups to oceanic islands
On page 104, Coyne has a chart of native groups in oceanic islands and groups that are usually missing. Plants, birds, and insects are in the native group and land mammals, reptiles, amphibians and freshwater fish are in the missing category. Coyne explains that this is because the native species can colonize the oceanic island trhough long-distance dispersal. What are some examples of species that have been found on oceanic islands that would fit into the missing group? How did they get there? How are they able to sustain their population?
