Boundary zone between two unique community types.

transition zone between two or more ecosystems.

In ecology, a zone of transition from one major plant community to another. For example, the forest–tundra ecotone in high northern latitudes is a zone of patchy and often stunted tree growth intermix [..]

the transitial zone between adjacent biotic communities, often with unique nutrients and ecological relationships.

the transition zone between very diverse ecosystems e.g. from tropical rainforest to savanna.

The edge of a habitat; quite often the edge between two different habitats The number of species is generally pretty high along an edge.

(Gk: oikos= house; teino= to stretch; ) a landscape boundary which exists between two or more adjacent communities or habitats, also known as edge.

a transitional zone between two adjacent communities containing species characteristic of both as well as other species occurr ing only within the zone.

Transition area between adjacent ecological communities (e.g., between forests and grasslands).

A transition between two or more different habitats; e.g. between forest and grassland.

Habitat created by juxtaposition of different habitats that merge together (may be used by "edge" species like cowbirds.)

The transition zone between two biotic communities, such as between the Ponderosa pine forest type and the mixed conifer forest, which is found at higher elevations than the pine.

A habitat created by the juxtaposition of distinctly different habitats; an edge habitat; or an ecological zone or boundary where two or more ecosystems meet.

A habitat created by the juxtaposition of distinctly different habitats; an edge habitat; or an ecological zone or boundary where two or more ecosystems meet.

a transition zone between two distinctly different ecosystems or communities.

  transitional zone or area between ecological communities.

The transition zone between communities, such as between uplands and wetlands. These transitional areas can be unusually rich in flora and fauna, with elements from both of the adjoining communities.
