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 ...
Particularly common types of secondary succession include responses to natural disturbances such as fire, flood, and severe winds, and to human-caused disturbances such as logging and agriculture. In secondary succession, the soils and organisms need to be left unharmed so there is a way for the new material to rebuild. [9]
Success and succession happen in tandem in boreal forests. Primary succession, while part of the original landscape formation, is not vital like secondary succession. [10] Secondary succession consists of varied events: wildfires, flooding, mudslides and even excessive insect foraging act in this progression and cycle of boreal forests. [10]
Secondary habitat formers are typically attached to, [3] [12] [13] [14] entangled around, [15] [16] or embedded within [17] [18] the primary habitat former. Habitat cascades are strongest when the secondary habitat former is more effective than the primary habitat former at allowing focal organisms to avoid stress and enemies, and find ...
The remainder is consumed by animals while still alive and enters the plant-based trophic system. After plants and animals die, the organic matter contained in them enters the detritus-based trophic system. [15] Ecosystem respiration is the sum of respiration by all living organisms (plants, animals, and decomposers) in the ecosystem. [16]
In scientific ecology, climax community or climatic climax community is a historic term for a community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state. This equilibrium was thought to occur because the climax community is ...
For gap dynamics to occur in naturally disturbed areas, either primary or secondary succession must occur. Ecological secondary succession is much more common and pertains to the process of vegetation replacement after a natural disturbance. Secondary succession results in second-growth or secondary forest, which currently covers more of the ...
The primary and secondary foundation species that make up a facilitation cascade can occur in one of two spatial configurations. [40] First are nested configurations in which the two foundation species are found intermixed or with one facilitator living on another, as in a mangrove pneumatophore providing a surface for oyster colonization.
