Lecture 10 Effects on Terrestrial Topography Dispersal and Barriers Data on land and water continuity enables tests of dispersal Data on land and water barriers enables tests of vicariance Mountain Building and biogeography Mountain uplift creates barriers for lowland fauna and flora. High elevations form low latitude habitats for high latitude.
Mountains enable new kinds of habitats and terrestrial islands and habitat zonation.
