Ecological Succession

Terms and concepts related to ecological succession

ecological succession

the process by which ecosystems change and develop over time, involving a series of progressive changes in species composition and community structure.

primary succession

the series of community changes that occurs on an entirely new habitat that has never been colonized before, such as lava flows or newly formed sand dunes.

secondary succession

the process of ecological change that occurs in an area where a disturbance has destroyed a community but left the soil intact, such as after a forest fire or flood.

pioneer species

the first species to colonize previously disturbed or undeveloped land, playing a crucial role in establishing a new ecosystem.

climax community

the final, stable stage of ecological succession, where a diverse array of species is balanced with the environment.

intermediate community

a stage in ecological succession characterized by a mix of species, typically occurring after pioneer species and before a climax community.

pioneer community

the initial stage of ecological succession where pioneer species establish themselves, paving the way for later, more complex communities.

intermediate disturbance hypothesis

a theory suggesting that ecosystems experiencing occasional disturbances can maintain higher levels of biodiversity compared to those with frequent or rare disturbances.

mosses and lichens

are examples of pioneer species that colonize barren environments, facilitating soil formation and enabling subsequent plant growth.

substrate

the underlying surface or material on which an ecosystem develops, providing the necessary conditions for plant and animal life.
