Changes in communities with time
Primary succession
Xeric succession (see the figure below)
e.g., volcanic succession
Mesic succession
Representative of primary, xeric succession (Whittaker 1975). Vegetation becomes tall with increasing time. - Succession on Mount Usu after the 1977-78 eruptions

A rolling stone gathers no moss
No moss stage in the succession (Tsuyuzaki 1987) -
You can't squeeze blood out of stone
No annual plant stage in the succession (Tsuyuzaki 1994) - Unsung heroes in the plant community
Perennial plants derived from vegetative reproduction were dominated soon after the eruption (Tsuyuzaki 1989) - Fable of the hare and the tortoise (Tsuyuzaki 2009)

Quiz
- Give some examples of arrested succession and discuss the mechanisms.
- A city lot is undergoing succession. Your goal is to reestablish a forest community. Under each of the following (example) conditions, what would you do? a) succession has been arrested by strong dominance of an exotic shrub such as Scot's bloom; b) there are serious barriers to immigration; c) soils have become compacted over the years; d) all of the above. Assess the nature of the succession if left alone, then determine if you will be accelerating, deflecting, or correcting the succession tract. Give brief examples of your tactics.
- Name some stochastic events and give examples about how they might alter succession.
- Contrast facilitation with inhibition as succession mechanisms. What does each predict concerning the order and structure of succession? Are these concepts mutually exclusive?
- List five major factors or processes that would produce a plant association distinct from the climatic climax type in an region where you like.
