-Succession is a gradual change in communities over time. Each community changes the environment so that it becomes suitable for new species to live there. The final community is known as the climax community.
-In the early stages of succession, abiotic factors are most important in determining which species can survive. Pioneer species have adaptations that allow them to colonise these hostile environments. As succesion proceeds, biotic factors become more significant.
-species diversity tends to increase as succession proceeds
