The sequences of succession are thus entirely dependent on life-history characteristics such as the specific amount of energy a species allocates to growth. [ 3 ] The climax community is composed of the most "tolerant" species that can co-exist with other species in a more densely populated area.
Forest succession is the process by which species recover and regenerate after a disturbance. The type of disturbance, the climate and weather conditions, the presence of colonizing species, and the interactions among species all influence the path that succession will take. Species diversity and composition fluctuate throughout succession.
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 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 ]
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 .
Despite the species loss that occurs with primary forest removal, secondary forests can still be beneficial to ecological and anthropogenic communities. They protect the watershed from further erosion and provide habitat; secondary forests may also buffer edge effects around mature forest fragments and increase connectivity between them. [6]
Xerosere is a plant succession that is limited by water availability. It includes the different stages in a xerarch succession.Xerarch succession of ecological communities originated in extremely dry situation such as sand deserts, sand dunes, salt deserts, rock deserts etc.
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.
