Question

Quizplus · Accepted Answer

Vicariance and dispersal are the two primary mechanisms that influence biogeographic patterns. Vicariance involves the splitting of a once continuous distribution range due to geological or climatic changes, while dispersal involves the movement of species from one region to another, either by crossing barriers or through long-distance transport. Both vicariance and dispersal have shaped the distribution of species and contributed to the formation of biogeographic regions.
