Observations of plant and animal phenological records, remote sensing observations and the timing of snow and ice cover from all continents and several oceans show that many physical and biological natural systems are changing their seasonal timing, particularly due to increases in temperature.

We invite contributions with cross-disciplinary perspectives that present seasonality changes based on recent plant and animal phenological observations, historical documentary sources, or seasonality measurements using climate data, remote sensing, flux measurements or modelling studies. We seek contributions across all spatial and temporal scales that compare and integrate seasonality changes, emphasize applications, discuss species interactions and decoupling and that advance our understanding of seasonality response to long-term climate change and single extreme events.
