populations to move among landscapes between habitat «
islands» such as mountain tops, forest fragments and
isolated wetlands) and corridor ecology.

island populations that were roughly equivalent to that between
island and mainland localities, suggesting that
island populations have been
isolated from each other for about as long as they have been
isolated from the mainland.
