Facilitation Model. Based on the assumption that only particular species with qualities ideal for "early succession" can colonize the newly exposed landforms after an ecological disturbance. These "colonizing" qualities include: highly effective methods of dispersal, the ability to remain dormant for long periods of time, and a rapid growth rate.
Ecological facilitation or probiosis describes species interactions that benefit at least one of the participants and cause harm to neither. [1] Facilitations can be categorized as mutualisms , in which both species benefit, or commensalisms , in which one species benefits and the other is unaffected.
Facilitation cascades differ from the facilitation model of succession [8] because species accumulate in the ecosystem due to the direct and indirect effects of the primary and secondary facilitator, whereas in the succession, early species that play a facilitative role are, over time, replaced by later-stage species.
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]
In this model, early invaders have major impacts on the invasion success of species that arrive later. Other modelling studies suggested that priority effects may be especially important when invasion frequency is low enough to allow species to become established before replacement, [ 15 ] or when other factors that could drive assembly (e.g ...
[1] [2] [3] Presently, there is more of a consensus that the mechanisms of facilitation, tolerance, and inhibition all contribute to autogenic succession. [4] The concept of succession is most often associated with communities of vegetation and forests, though it is applicable to a broader range of ecosystems.

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 ...
