The term pioneer species is also used to refer to the first species, usually plants, to return to an area after disturbance as part of the process of secondary succession. Disturbances may include floods, tornadoes, forest fires, deforestation, or clearing by other means. [18] Pioneer species tend to be fast-growing, shade-intolerant, and tend ...
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 pioneer organism, also called a disaster taxon, is an organism that colonizes a previously empty area first, or one that repopulates vacant niches after a natural disaster, mass extinction or any other catastrophic event that wipes out most life of the prior biome. [1]
An example of pioneer species, in forests of northeastern North America are Betula papyrifera (White birch) and Prunus serotina (Black cherry), that are particularly well-adapted to exploit large gaps in forest canopies, but are intolerant of shade and are eventually replaced by other shade-tolerant species in the absence of disturbances that ...
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.
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 ...
A seral community of shrubs and grasses on an abandoned field. A seral community is an intermediate stage found in ecological succession in an ecosystem advancing towards its climax community.
A ruderal species is a plant species that is first to colonize disturbed lands. The disturbance may be natural – for example, wildfires or avalanches – or the consequences of human activities, such as construction ( of roads , of buildings , mining , etc.) or agriculture (abandoned fields, irrigation , etc.).
