WebEcotones can be either gradients or discontinuities (i.e., gradual or sharp) controlled by environmental conditions, habitat availability, disturbance or biotic interactions. The identity of ecotones (i.e., the type and extent of commu-nity composition shifts) can vary spatially and temporally (Danz et al. 2013). Ecotones and their properties ... WebDue to high edge-to-surface ratios in small forest patches, a large proportion of forests is affected by edge influences involving steep microclimatic gradients. Although forest edges are important ecotones and account for 20% of the global forested area, it remains unclear how biotic and abiotic drivers affect forest edge microclimates at the ...

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: WebEcotones often occur along ecological gradients. Such gradients are created as a result of spatial shifts in elevation, climate, soil, and many other environmental factors.
