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 ...
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.
For example, we can examine succession in the Loess Plateau in China. In the graph on page 995 of the paper "Plant Traits and Soil Chemical Variables During a Secondary Vegetation Succession in Abandoned Fields on the Loess Plateau" by Wang (2002), we can see the initial dominance of the Artemisia scoparia, the pioneer species.
Pioneer species play an important role in creating soil in primary succession, and stabilizing soil and nutrients in secondary succession. [2] For humans, because pioneer species quickly occupy disrupted spaces they are sometimes treated as weeds or nuisance wildlife, such as the common dandelion or stinging nettle.

Primary succession may happen after a lava flow or the emergence of a new island from the ocean. 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 ...
