What is the difference between ecological succession and evolution?
What is ecological succession if there was no vegetation prior?
Succession describes the sequential appearance and disappearance of species in a community over time. In primary succession, newly exposed or newly formed land is colonized by living things; in secondary succession, part of an ecosystem is disturbed and remnants of the previous community remain.
Succession refers to a directional, predictable change in community structure over time (Grime 1979, Huston & Smith 1987). This change is due to shifts in the presence and relative abundance of...
- Ecological Succession. Communities with a stable structure are said to be at equilibrium. Following a disturbance, the community may or may not return to the equilibrium state.
- Primary Succession and Pioneer Species. Primary succession occurs when new substrate is formed or rock is exposed: for example, following the eruption of volcanoes, such as those on the Big Island of Hawaii.
- Secondary succession. A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire (Figure \\(\\PageIndex{3}\\)). Wildfires will burn most vegetation and kill those animals unable to flee the area.
- Climax Communities? Ecological succession is a foundational concept in ecology, which as a field examines the structure and dynamics of biological communities.

Ecological succession where there was no vegetation prior is called primary succession. We can observe primary succession on bulldozed sites, after an intense fire, or following a volcanic eruption, for example. The first plant species to show up have the ability to very quickly colonize and grow in these bare areas. Depending on the region, these ...
The last stage of succession is the climax community. In a forest, climax species are those that can grow in the shade of taller trees – hence the name shade-tolerant species. The composition of climax communities varies geographically. In parts of the eastern United States, a climax forest will be made of sugar maples, eastern hemlock, and America...
The dark shade and tall canopies of climax forests provide shelter for a number of specialized birds, mammals, and other organisms. The cerulean warbler, wood thrush, and red-cockaded woodpecker are dwellers of old forests. The threatened spotted owl and Humboldt fisher both require large stands of late successional redwood and Douglas-fir forests....
There is also considerable value in early successional habitat. These shrubland and young forests rely on recurring disturbances that set succession back. Unfortunately, in many places, these disturbances often turn forests into housing developments and other land uses that short-cut the ecological succession process. As a result, shrublands and yo...

Ecological succession, a dynamic process involving gradual changes in biological communities over time, encompasses two main types: primary succession, where life gradually colonizes a new habitat, and secondary succession, triggered by a disaster that disrupts an existing community, instigating shifts in species composition. Created by Sal Khan.
Types of Succession. The successional process has been categorized into two types, based on the properties of the habitat on which it occurs. Primary succession, the colonization of habitats...
