In an ecotone, the species that become abundant are called **edge species** or **edge specialists**. Edge species thrive in the transition zone or boundary between two distinct habitats or ecosystems. Ecotones are areas of transition characterized by a mixture of species from adjacent ecosystems, resulting in unique ecological conditions and species compositions.

Edge species often exhibit adaptations that allow them to thrive in the dynamic environmental conditions found at the boundaries of ecosystems. These adaptations can include tolerance to fluctuating environmental factors (such as light, temperature, and moisture), as well as specialized behaviors or physiological traits that give them a competitive advantage in the ecotone.

Ecotones are important for biodiversity because they often support a greater variety of species than either of the adjacent ecosystems alone. Edge species contribute to the overall ecological diversity and resilience of the landscape by utilizing resources from both ecosystems and by facilitating interactions between species from different habitats.
