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. Identify the independent variable in the experiment. Succession is a structural change in a community and its nonliving environment over time. It is an index of the climate of the area.
