The Ecotone Effect refers to the phenomenon where biodiversity is higher in transition zones (ecotones) between two ecosystems. Ecotones contain species from both adjacent ecosystems and may also support specialized species that are adapted to the unique conditions of the boundary area. This effect is called the Edge Effect, as seen in areas like mangroves (between land and sea) or estuaries (between freshwater and saltwater ecosystems).
