The principle of faunal succession is based on the four assumptions of (1) the validity of the principle of superposition; (2) the sequence of fossils are the same everywhere (3) rock layers of different ages will contain different types of fossils; and (4) the validity of the principle of original horizontality. î î î.
This non-native species causes extensive ecological damage to native habitats. Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires.Secondary succession is usually much quicker than primary succession for the following reasons: There is already an existing seed bank of suitable plants in the soil.his non-native species causes extensive ecological damage to native habitats.
