Describing areas where two different ecosystems meet and interact, often leading to unique environmental conditions and species.
The ecotonal region between the forest and the grassland is rich in biodiversity.
Ecotonal is formed from "eco-" (from Greek "oikos", meaning house or environment) and "tonal" (from Latin "tonalis", meaning relating to tone). The word describes areas where different ecological communities meet, reflecting the 'tone' or character of both environments.
Think of 'eco-' as relating to the environment or 'house' and 'tonal' as relating to the character or 'tone' of that environment. This helps you remember that 'ecotonal' refers to the meeting point of different ecological areas.
