Photoperiodism in Animals
The animals who are living in the latitudes use photoperiodism to adjust themselves to some development strategies or seasonal behaviour. Photoperiodism in animals is a process in which some animals respond in a particular time of the year. It also affects the color of fur of some animals. For example – singing of birds, seasonal breeding occurs in many animals and so on.
Photoperiodism: Meaning, Process and Examples
Photoperiodism is a biological response of plants and animals to change in the proportion of dark and light. Garner and Allard first studied photoperiodism in plants in 1920. “Photo” means light and “period” means the length of time. Plants require light to bloom. The duration when the plant is required to bloom is known as critical photoperiod. Photoperiodism helps to determine the flowering season of different types of plants.
