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.
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.
An example of such "whole-community" facilitation is substrate stabilization of cobble beach plant communities in Rhode Island, US, by smooth cordgrass (Spartina alterniflora). [6] Large beds of cordgrass buffer wave action, thus allowing the establishment and persistence of a community of less disturbance-tolerant annual and perennial plants ...
Autogenic succession can be viewed as a secondary succession because of pre-existing plant life. [6] A 2000 case study in the journal Oecologia tested the hypothesis that areas with high plant diversity could suppress weed growth more effectively than those with lower plant diversity.
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 ...
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
Example: sustainable agro-ecosystems, multispecies aquaculture, and introducing agroforestry plots into residential property to generate primary production at multiple vertical levels. Mitsch and Jorgensen [3] identified 19 Design Principles for ecological engineering, yet not all are expected to contribute to any single design:
An ideal examples of r-selected groups are algae. Based on the contradictory characteristics of both of these examples, areas of occasional disturbance allow both r and K species to benefit by residing in the same area. The ecological effect on species relationships is therefore supported by the intermediate disturbance hypothesis.
