Gradients and ecotones

WebJan 1, 2015 · The environmental gradients occurring in estuaries can be either classified as ecotones, represented by the transition community between the freshwater and marine species, or ecoclines comprised of a … 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:
