	Free Essay Ecological Succession
		Succession is a result of these changes and is defined as a series of progressive changes in an area with one community replacing the other until a climax community is created.
		Primary succession is the colonisation of an area which has not supported an ecosystem before, eg sand dunes, volcanoes and new ponds.
		The sequence of communities during succession is known as a sere, the type of sere is determined by the environment being colonised, eg a hydrosere is a series of successions in an aquatic environment and a xerosere is a succession beginning in a dry area.

	Succession - Wikipedia, the free encyclopedia
		Succession begins with arrival of the pioneer species and leads eventually to establishment of a climax community.
		In primary successions pioneer species are typically hardy plants that survive under harsh conditions.
		Succession may be thought of as a more general term for any possible progression, as in chord progression or harmonic progression, though not all simultaneity successions are harmonic progressions.

		Primary succession was documented in a devastated landscape during a five-year period on the eastern flank of Mt. St.
		Key succession concepts: physical amelioration of the stressful environment and favorable microsites may be more important than autogenic processes during early primary succession; species sequences and the mechanisms of colonization during primary succession may differ from those common to secondary succession.
		Key succession concepts: avian influence on succession appears to be most pronounced at intermediate seral stages; birds may directly effect succession through seed dispersal and destruction; plant/animal relationships appear to be integral in successional processes.

	LJ's_notesII
		Primary succession is the colonization and succession that occurs on a new surface, or landscape (e.g., brought about by lava flow, volcanic eruption, glaciation).
		A better way to view the final stage of succession is as a mature community, in which the community represents the final stage of succession but is not in any kind of static equilibrium.
		Secondary succession has many similarities to primary succession in terms of the types of plants that occur on the landscape throughout the successional sequence.

		Ecological succession is a fundamental concept in ecology which states that there is a definable sequence of successional stages through which an ecosystem will pass.
		Primary succession by definition starts with a bare substrate and a pioneer community, whereas secondary succession occurs after an existing successional stage is disturbed (such as, for example, following a fire, a flood, volcanic eruptions, or deforestation).
		The very early stage of an ecological succession may be a bare rock sligthly covered by moss, or a mud flood slowly being colonized by a grass.

		Succession is a directional non-seasonal cumulative change in the types of plant species that occupy a given area through time.
		Succession stops when species composition changes no longer occur with time, and this community is said to be a climax community.
		Secondary succession - is the invasion of a habitat by plants on land that was previously vegetated.

		A primary forest is a forest that has never been logged and has developed following natural disturbances and under natural processes, regardless of its age.It is referred to "direct human disturbance" as the intentional clearing of forest by any means (including fire) to manage or alter them for human use.
		Also included as primary, are forests that are used inconsequentially by indigenous and local communities living traditional lifestyles relevant for the conservation and sustainable use of biological diversity.
		Old growth forest stands are stands in primary or secondary forests that have developed the structures and species normally associated with old primary forest of that type have sufficiently accumulated to act as a forest ecosystem distinct from any younger age class.

		Primary succession is the first stage of the succession of plant life from barren land to fully functioning plant ecosystems e.g.

	Plant Succession
		Another example of plant succession occurs as shallow ponds gradually fill in with soil washed in from the surrounding terrain and organic matter produced by underwater plants.
		In general, plant succession is a reflection of the increasing efficiency of the community at intercepting the energy of the sun and converting it into chemical energy.
		Studying succession in six different biomes, including tropical rain forest, temperate rain forests as well as taiga, it was found that — if nothing (hurricanes, fire) has disturbed the climax forest — eventually the soil becomes less fertile and the biomass of the forest declines.

		Ecological succession is the change in a community as a result of a disturbance.
		Primary succession is when a community forms in a previously lifeless habitat or one that had severe disturbance, such as in a cooled lave field, or in bare rock left behind by a retreating glacier.
		Volcanic eruption is another disturbance that occurs mostly on island chains, which causes primary succession when lava destroys the soil and organisms in the area, allowing new organisms move in.
