Home Range – A home range is an area in which an animal lives and moves on a daily or periodic basis (a little bigger than habitat – home → office → home).This thesis aims to study the relationship between architecture and its environment.

Habitat – surroundings in which an organism lives (home).

Ecotone – zone of transition between two ecosystems.

Which one of the following terms describes not only the physical space occupied by an organism but also its functional role in the community of organisms?

For example, a large number of different species of insects may be pests of the same plant, but they can co-exist as they feed on different parts of the same plant.

This is because of the competition with one another until one is displaced.

No two species in a habitat can have the same niche.

A niche is unique for a species while many species share the habitat.

activities and responses specific to the species). where it lives) whereas niche can be thought of as its “profession” (i.e.

The habitat of a species is like its ‘address’ (i.e.

If we have to conserve species in its native habitat, we should have knowledge about the niche requirements of the species.

Niche plays an important role in the conservation of organisms.

physical & chemical niche – temperature, land shape, land slope, humidity & another requirement.

reproductive niche – how and when it reproduces,.

habitat niche – where it lives, food niche – what is eats or decomposes & what species it competes with,.

In nature, many species occupy the same habitat, but they perform different functions:.The functional characteristics of a species in its habitat is referred to as “niche” in that common habitat.Niche refers to the unique functional role and position of a species in its habitat or ecosystem.For example, the density of birds is greater in the ecotone between the forest and the desert.In the terrestrial ecosystems edge effect is especially applicable to birds.The organisms which occur primarily or most abundantly in this zone are known as edge species.Sometimes the number of species and the population density of some of the species in the ecotone is much greater than either community.Edge effect refers to the changes in population or community structures that occur at the boundary of two habitats (ecotone).

Ecocline occurs across the environmental gradient (gradual change in abiotic factors such as altitude, temperature (thermocline), salinity (halocline), depth, etc.).Ecocline is a zone of gradual but continuous change from one ecosystem to another when there is no sharp boundary between the two in terms of species composition.A well-developed ecotone contains some organisms which are entirely different from that of the adjoining communities.Usually, the number and the population density of the species of an outgoing community decreases as we move away from the community or ecosystem.It has conditions intermediate to the adjacent ecosystems.It may be narrow (between grassland and forest) or wide (between forest and desert).Picture Credits Characteristics of Ecotone Other examples are grassland(between forest and desert), estuary(between fresh water and salt water) and riverbank or marshland (between dry and wet).the mangrove forests represent an ecotone between marine and terrestrial ecosystem. Ecotone is the zone where two communities meet and integrate.An ecotone is a zone of junction or a transition area between two biomes (diverse ecosystems).
