Ecological succession is the process of change in the species that make up an ecological community over time. The process of succession occurs either after the initial colonization of a newly created habitat, or after a disturbance substantially alters a pre-existing habitat. [1]
One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...

[2] [3] [4] Second, interspecific competition results in one species driving a competitor to extinction and becoming dominant in the ecosystem. [2] [3] [4] Third, moderate ecological scale disturbances prevent interspecific competition. [2] [3] [4] The hypothesis is ambiguous with its definitions of the terms "intermediate" and "disturbance".
Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting ...
Cyclic succession is a pattern of vegetation change in which in a small number of species tend to replace each other over time in the absence of large-scale disturbance. Observations of cyclic replacement have provided evidence against traditional Clementsian views of an end-state climax community with stable species compositions .
[1] [2] [3] Presently, there is more of a consensus that the mechanisms of facilitation, tolerance, and inhibition all contribute to autogenic succession. [4] The concept of succession is most often associated with communities of vegetation and forests, though it is applicable to a broader range of ecosystems. In contrast, allogenic succession ...
In ecology, allogenic succession is succession driven by the abiotic components of an ecosystem. [1] In contrast, autogenic succession is driven by the biotic components of the ecosystem. [1] An allogenic succession can be initiated in a number of ways which can include: Volcanic eruptions; Meteor or comet strike; Flooding; Drought; Earthquakes
