High Arctic plant phenology is determined by snowmelt patterns but duration of phenological periods is fixed: an example of periodicity
The duration of specific periods within a plant’s life cycle are critical for plant growth and performance. In the High Arctic, the start of many of these phenological periods is determined by snowmelt date, which may change in a changing climate. It has been suggested that the end of these periods...

The duration of specific periods within a plant’s life cycle are critical for plant growth and performance.
