Gradients and ecotones
An ecotone is often associated with an ecocline: a "physical transition zone" between two systems. The ecotone and ecocline concepts are sometimes confused: an ecocline can signal an ecotone chemically (ex: pH or salinity gradient), or microclimatically (hydrothermal gradient) between two ecosystems. In contrast: Web9 Ecotones and Ecological Gradients 149. ecological framework for the study of ecotones was given by Odum in 1953. Odum discussed the ecotone effect, which he characterized …
