|
a region of transition between two ecological communities
|
|
|
an abrupt spatial change in landscape typology that may inhibit movement across the landscape
|
|
|
a gradual, continuous change in species composition or physiochemical characteristics between two ecosystems or communities of organisms across an environmental gradient
|
|
|
the smallest ecologically distinct landscape features in a landscape mapping and classification system, representing relatively homogeneous, spatially explicit landscape functional units that are useful for stratifying landscapes into ecologically distinct features for the measurement and mapping of landscape structure, function and change

an aggregation of patches that supports a metapopulation of a particular species

Detailed explanation-1: -ecocline (plural ecoclines) A gradation from one ecosystem to another when there is no sharp boundary between the two. It is the joint expression of associated community (coenocline) and complex environmental gradients.
Detailed explanation-2: -Ecocline is a terminology used in ecology. This concept is defined as the physiochemical gradient of a characteristic or a trait of a species across a specific geographical range. It deals with traits such as pH variation, salinity variation, water density variation and chemical variation.
Detailed explanation-3: -An ecotone is a transition area between two biological communities, where two communities meet and integrate. It may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems).
Detailed explanation-4: -Physicochemical properties between two ecosystems are described by an ecocline, a recognised new zone formed by combining two homogeneous ecosystems. An ecotone is a specified new zone formed by combining two homogeneous ecosystems.
