Why do different areas have different climax communities?
Climax is determined by the regional climate. The processes of succession and modification of environment overcome the effects of differences in topography, parent material of the soil, biotic factor and other factor. The whole area would be covered with uniform plant community.
Are climax communities common?
Still, the notion of a climax community remains a common, often useful way to understand how ecosystems develop and change, and how their species interact.
What factors determine a climax community?
These will be climaxes, controlled by soil moisture, soil nutrients, activity of animals and other factors. According to this theory, climate is only one of the several factors, any of which may have a controlling influence on the structure and stability of the climax.
What are the treats to climax community?
It is clear that stable climax communities in most areas can coexist with human pressures on the ecosystem, such as deforestation, grazing, and urbanization.
How does the structure of a climax community change?
Climax communities undergo changes in structure as a result of birth, death and growth processes in the community. 1. Mono-climax Theory: According to the mono-climax theory of succession (Clements, 1936), every region has one climax community toward which all communities are developing.
How is the climax community in a successional series?
It is the final or stable community in a successional series. It is self-perpetuating and in equilibrium with the physical and biotic environment. Climax communities undergo changes in structure as a result of birth, death and growth processes in the community. 1. Mono-climax Theory:
Which is the best theory of the climax?
According to this theory, climate is only one of the several factors, any of which may have a controlling influence on the structure and stability of the climax. This allows many climaxes in a climate region and is, therefore, called the poly-climax theory.
What’s the difference between poly climax and mono climax?
Whereas the mono-climax theory allows for only one climatic climax in a region and the poly-climax theory allows several climaxes, the climax-pattern hypothesis allows a continuity of climax types varying gradually along environmental gradients and not clearly separable into discrete climax types. 4. Climax as Vegetation:
