Succession – learning outcomes You should all be able to: • Define succession • Identify the two types of succession and the difference between them Most of you should be able to: • Distinguish between zonation and succession Some of you might be able to: • Describe the change in specific species through the process of succession within a named habitat.
Succession – the orderly process or change over time in the composition of a community. Time
Two types of succession • Primary – the colonization of newly created land by organisms
Two types of succession • Secondary – This occurs in places where the previous communities have been destroyed e.g. forest fire.
Watch the simulation and make notes about what happens at the different stages. • http://www.mrphome.net/mrp/succession.swf
Zonation. The arrangement or patterning of plant communities or ecosystems into bands in response to change in some environmental factor over distance. What environmental factors cause changes to the vegetation? Can you think of any real-world examples where this might happen? http://www.diercke.com/kartenansicht.xtp?artId=978-3-14-100790-9&stichwort=Andes&fs=1 http://razottoli.wordpress.com/introduction/rocky-intertidal-zonation-patterns/
Primary succession - stages • On your handout match the correct description to each stage of primary succession
Case study – sand dunes (primary succession) • Read the case study and answer the questions. • Make sure you are taking notes of the different organisms found at each stage – this will be your named habitat.
On a sheet of paper… • Define the term succession. • Define primary and secondary succession and the difference between them. • What are the main differences between succession and zonation?
