ecological succession
Ecological succession is the process of how species compositions change in an Community (ecology), ecological community over time.
The two main categories of ecological succession are primary succession and secondary succession. Primary successi ...

climax community
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, hav ...
. In many cases more than one seral stage evolves until climax conditions are attained. A prisere is a collection of seres making up the development of an area from non-vegetated surfaces to a climax community.
A seral community is the name given to each group of plants within the succession. A
primary succession
Primary succession is the beginning step of ecological succession where species known as pioneer species colonize an uninhabited site, which usually occurs in an environment devoid of vegetation and other organisms.
In contrast, secondary su ...
describes those plant communities that occupy a site that has not previously been vegetated. These can also be described as the
pioneer community.
Computer modeling
Computer simulation is the running of a mathematical model on a computer, the model being designed to represent the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determin ...
is sometimes used to evaluate likely succession stages in a seral community.
Depending on the substratum and climate, a seral community can be one of the following:
;
Hydrosere: Community in water
;
Lithosere: Community on rock
;
Psammosere
A psammosere is the sequence of plant succession that has been initiated on sand.
A psammosere is an intermediate stage in ecological succession, known as a seral community, that begins life on newly exposed coastal sand. The most common psammo ...

secondary succession
Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an a ...
