For example, species diversity almost necessarily increases during early succession as new species arrive, but may decline in later succession as competition eliminates opportunistic species and leads to dominance by locally superior competitors. Climax succession is not a term used to describe species succession over time, rather, a climax community is one that, over time, has reached a steady state. True . Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the communitys ecological structure to an earlier stage.

Mycorrhizal fungi have a mutualistic relationship with various species of plants and increase the plant growth and survival. The annual production and use of energy is balanced in such a community. Gleason argued that species distributions responded individualistically to environmental factors, and communities were best regarded as artifacts of the juxtaposition of species distributions. For example, when larger species like trees mature, they produce shade on to the developing forest floor that tends to exclude light-requiring species.

Seedlings establishing themselves in a heavily logged area where the seed-tree cutting method was employed, Lichen and grass communities establishing themselves on a recently-formed island, resulting from an uplift in the ocean bedrock, Coral reef and aquatic wildlife communities that have re-established themselves in regions of the South Pacific that were evacuated following the nuclear tests conducted by the U.S. military, Lichens re-establish themselves on rocks and shallow soil beds following a tundra fire, Native grass communities forming after a wildfire burned through a meadow/woodland ecosystem. An example of pioneer species, in forests of northeastern North America are Betula papyrifera (White birch) and Prunus serotina (Black cherry), that are particularly well-adapted to exploit large gaps in forest canopies, but are intolerant of shade and are eventually replaced by other shade-tolerant species in the absence of disturbances that create such gaps.
