What is the oldest stage of succession apes. forest Pioneer species are important in ecological succession. The formation of organic material in these areas typically occurswith the accumulation ofwind-carried soil erosion, nutrients deposited by flowing bodies of water, and erosion of bedrock. Clements explicitly analogized the successional development of ecological communities with ontogenetic development of individual organisms, and his model is often referred to as the pseudo-organismic theory of community ecology.

[21] There are "opportunistic" or "pioneer" species that produce great quantities of seed that are disseminated by the wind, and therefore can colonize big empty extensions. In general, communities in early succession will be dominated by fast-growing, well-dispersed species (opportunist, fugitive, or r-selected life-histories). Evolution is any change in the proportions of different genotpyes in a population from one generation to the next. Two quotes illustrate the contrasting views of Clements and Gleason. It is self-perpetuating and in equilibrium with the physical habitat. Please be advised that you will be liable for damages (including costs and attorneys fees) if you materially Omissions? [12], The trajectory of successional change can be influenced by site conditions, by the character of the events initiating succession (perturbations), by the interactions of the species present, and by more stochastic factors such as availability of colonists or seeds or weather conditions at the time of disturbance. Their quick reproduction and growth also categorizes them as R-selected species.

This is different from primary succession - primary succession occurs when there is no prior vegetation on the landscape and there is no seedbank. From about 1900 to 1960, however, understanding of succession was dominated by the theories of Frederic Clements, a contemporary of Cowles, who held that seres were highly predictable and deterministic and converged on a climatically determined stable climax community regardless of starting conditions.
