As we travel away from a community or ecosystem, the quantity and population density of the species in that community or ecosystem usually diminishes.
It has circumstances that are transitional between the neighbouring ecosystems.This suggests that there is a fragile zone where plants and wildlife coexist. Most ecosystems do not have distinct boundaries.Ecotones are difficult environments for inner organisms, but they are rich in opportunities for edge organisms.Ecotones indicate a physical transition from one ecosystem to another, as well as a change in living conditions, including habitats and niches.The coexistence of different species and living forms is influenced by environmental changes, both within ecosystems and at their edges, where ecotones may arise.Ecotones pique the interest of biologists for a variety of reasons.Ecotones are formed when environmental conditions change abruptly.Ecotones are locations where two or more biological communities, ecosystems, or biotic regions meet.Study the Basics of the Environment Here. The most common example of this condition can be seen on Mont Ventoux in France, which serves as a barrier between the vegetation and wildlife of northern and southern France.A terrain serves as an obstructing boundary that serves as a species boundary.Mountain ranges are primarily responsible for the establishment of such ecotones because they exhibit a wide diversity of climatic conditions on their slope ranges.When there is a change in the physical environment, it might result in abrupt boundaries, as seen at the interface between sections of forest and cleared land.) Mountain ranges can also create ecotones due to changes in climatic conditions on the slopes. The section of the bank where these two ecosystems meet is one of nature’s most important ecotones.Īdditionally examples of ecotones include marshlands (between dry and wet ecosystems), mangrove forests (between terrestrial and marine ecosystems), grasslands (between desert and forest) and estuaries (between saltwater and freshwater). The forest will abruptly give way to the vast spaces of a grassland.Īnother example is a floodplain, which represents a transition from a terrestrial to aquatic ecology. The tree composition of the forest tends to shift slowly as temperature and rainfall conditions change. The transition from a forest to a grassland habitat is a famous example of an ecotone. The term “biome” was suggested by an ecologist Frederick Edward Clements in 1916, which refers to the term biological community.The world comprises a large variety of environmental types that are divided and grouped into different types of biomes and based primarily on adaptation, range of temperatures, weather and climatic conditions.A biome can be defined as a large biological community or an ecosystem where a wide variety of organisms, including plants, animals, birds, insects, and humans, are used to living in a certain type of climate.Ecotones have significant biotic and microenvironmental change gradients their locations are often dynamic and they are among the first areas to respond to new environmental stresses like climate change, increased grazing intensity, or pollution.They span from mountain treelines to the boundaries of vast biomes and ecoregions (eg, Mediterranean and arid).Ecotones exist at a variety of spatial dimensions, ranging from natural ecotones across ecosystems and biomes to man-made borders.Ecotones are locations where ecological communities, ecosystems, or ecological regions abruptly transition along a gradient of environmental change.This zone can traverse lengthy portions of two ecosystems and is a site where both ecosystems’ traits can be seen.
An ecotone is a zone when an ecosystem (or community) abruptly transitions from one to another.

Ecotone(Environment Topic For UPSC Exam): Download PDF Here! What are Ecotones? Nowadays, the ecotone is regarded as one of the most important subjects in UPSC Exams, as it is regarded as the most sensitive section of the affected ecosystems to the surrounding environment. A vegetative transition zone between two plant communities, such as forest and grassland, is known as an ecotone.
