Gradients and ecotones
Did you know?
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 ... Webfrom observed gradients, from which Whittaker noted that no natural (i.e., based on patterns in the data) types could be discerned. Within this subsection he discussed zonation and ecotones, thenatureandmeaningofclimax,andtheinter-pretation of a phenomenological hierarchy relating the interdependence of organisms, spe-
WebMay 24, 2011 · Gradients in the composition and diversity (e.g. number of species) of faunal assemblages are common at ecotones between juxtaposed habitats. Patterns in the number of species, however, can be confounded by patterns in abundance of individuals, because more species tend to be found wherever there are more individuals. We tested …

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.
