Ecocline: A gradation from one ecosystem to another when there is no sharp boundary between the two. It is a gradual, continuous change in the species composition between two ecosystems or communities of organisms across an environmental gradient
Ecotone: An ecotone is a transition area between two biomes. It is 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.

An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces.
