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.
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 ]
An example may be in a beach dune system where the impact of the human race has caused footpath erosion to occur, affecting the vegetation so that feet trampling on the dune plants eventually destroys them. The uplands of Northern England were once covered by deciduous woodland. Some heather would have been present, but in relatively small amounts.
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 .
Ecological succession is the process by which a community changes over time, especially following a disturbance. In many instances, an ecosystem will change from a simple level of organization with a few dominant pioneer species to an increasingly complex community with many interdependent species.
White spruce (Picea glauca) is an example of a climax species in the northern forests of North America due to its ability to adapt to resource scarce, stable conditions, it dominates Northern forest ecosystem in the absence of a disturbance. [10] Other examples of climax species in old-growth forests: Canadian hemlock; Pacific silver fir; White fir
Stand dynamics stages during succession. An abstract diagram showing forest succession over time. Increase in biomass, biodiversity and soil thickness are also shown, as well as the fluctuation of different plant communities over the process of succession. Forest succession is the process by which species recover and regenerate after a ...
