More plants and animals arrive (the latter rafting over on flotsam or flying from nearby islands or the mainland), and some become established on the island. Additions to available species pools through range expansions and introductions can also continually reshape communities. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. Examples are the changes that occur after volcanos erupt and forest fires. Identify the oldest stage of succession shown in the figure above.
