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 ]
Ecological micro-succession and the competition-colonization trade-off in a bacterial meta-community on-chip.(A) sketch of a micron-scale structured bacterial environment based on microfluidics technology; (B) Fluorescent microscopy image of Escherichia coli (magenta) and Pseudomonas aeruginosa (green) inhabiting a device of the type depicted in A and which has been wettened with growth media ...
Chronosequences are often used to study the changes in plant communities during succession. [4] A classic example of using chronosequences to study ecological succession is in the study of plant and microbial succession in recently deglaciated zones. For example, a study from 2005 used the distance from the nose of a glacier as a proxy for site ...
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 ...
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 .
Early ecological succession theory maintained that the directional shifts from one stage of succession to the next were induced by the plants themselves. [1] In this sense, succession theory implicitly recognized priority effects; the prior arrival of certain species had important impacts on future community composition.
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 .
