Under seasonal dimorphism ( season , see season + di (two) + morphism , shape, see morphology ) refers to the seasonal occurrence of two distinctly different manifestations at a kind . Light and temperature are particularly important for this effect . Seasonal dimorphism can be caused by the occurrence of at least two generations of a species within a year. These differ significantly in their appearance (e.g. body size, color) within the seasons. An example of this is the country map .
Seasonal dimorphism can also occur in single individuals. Typical habitat for dwarf shrubs of the Phrygana is the formation of seasonally different leaf shapes.
