Surtsey, a volcanic island off the southern coast of Iceland, is an important example of a place where primary succession has been observed. [2] [3] On the other hand, secondary succession happens after disturbance of a community, such as from a fire, severe windthrow, or logging. Succession was among the first theories advanced in ecology.
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 ...
Eventually, early species, typically dominated by r-selected species, which prioritize fast rates of reproduction, are out-competed by K-selected species (species that become more dominant when there is competition for limited resources). [10] For example, we can examine succession in the Loess Plateau in China.
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 .

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
Ecological succession, a fundamental concept in ecology, refers to more-or-less predictable and orderly changes in the composition or structure of an ecological community Wikimedia Commons has media related to Ecological succession .
A seral community is an intermediate stage found in ecological succession in an ecosystem advancing towards its climax community. In many cases more than one seral stage evolves until climax conditions are attained. [1] A prisere is a collection of seres making up the development of an area from non-vegetated surfaces to a climax community.
