2021-06-20 09:26:44 Ecological Succession

When the course of succession is largely driven or determined by internal coactions then such type of succession is known as Autogenic Succession i.e. the change in both the environment and the community is brought about by the activities of organisms themselves. Change in the environment for example is brought about by plant shade or litter input to the soil which in turn will result in a change in structure and properties of soil leading to change in species composition with time.

When the course of succession is controlled by some external driving forces, i.e. the forces beyond the control of the indigenous organisms or the changes in the environment are caused by some external factor unaffected by the organism (e.g. storms, fire, etc.), such type of succession is known as allogenic succession.

Autogenic succession is largely mediated by direct or indirect competition for niche space, coupled with changes in the environment resulting from the colonization. Greater is the number of species, greater is the competition for the niche space Open / Comment
