A well-known example of a broad vicariant pattern of distribution is found in the plant genus Nothofagus (Nothofagaceae) in the Southern Hemisphere, with species distributed in South America, New Guinea, Australia, New Caledonia, and New Zealand and fossils known from Antarctica.
What is an example of vicariance?
An example of vicariance is the separation of marine creatures on either side of Central America when the Isthmus of Panama closed about 3 million years ago, creating a land bridge between North and South America.
What is vicariance and dispersal?
Biologists group allopatric processes into two categories: dispersal and vicariance. Dispersal occurs when a few members of a species move to a new geographical area, while vicariance occurs when a natural situation arises to physically divide organisms.
