Biotic Province

생물구

Definition

A geographic region defined by a characteristic assemblage of species with shared evolutionary history.

Detailed Explanation

Biotic provinces reflect the imprint of evolutionary history on species distributions — organisms from the same province share ancestors that radiated within that area. The concept was developed by Dice (1943) and refined by Hagmeier and Stults for North American mammals. Province boundaries often correspond to major geographic barriers. They are used in conservation planning to ensure protected area networks represent distinct evolutionary assemblages.
