An example of pioneer species, in forests of northeastern North America are Betula papyrifera (White birch) and Prunus serotina (Black cherry), that are particularly well-adapted to exploit large gaps in forest canopies, but are intolerant of shade and are eventually replaced by other shade-tolerant species in the absence of disturbances that create such gaps. Each transitional community that is formed and replaced during succession is called a stage in succession or a seral community. On newly created volcanic islands, for example, after the rock cools, seeds blown by the wind may lodge in crevices, germinate, and take root. Ecological succession is the process through which the organization of a biological community changes over time. (ii) Describe the role of pioneer species in early succession.
