Why “ecotone” is a great word
A region of transition where two distinct ecological communities meet and integrate. From eco- (a combining form representing ecology, from Greek oikos, "house" or "habitat") + -tone (from Greek tonos, "tension" or "stretching"), first attested in the early 20th century (1900–1905). Unlike a "biome," which names a vast, stable dominion like a taiga or a desert, or a "habitat," which describes the settled address of a particular species, an ecotone is the contested margin itself. It is the rippling gradient from forest to field where sunlight dapples the tall grass, the brackish estuary where freshwater currents braid with the salt tide, and the creeping treeline on a mountainside where hardy shrubs yield to alpine tundra—a living seam where difference generates a richer, more precarious vitality.
