Summary of identified climate drivers of phenological change in the southern hemisphere.

‘None identified’ refers to studies that explicitly examined relationships between the climate variables considered in that study and phenology but found no statistical significant relationships. Note some studies identified more than one climate driver. Total is the number of datasets that were considered to have at least one climate driver for phenological variability or change. No change indicates a trend was calculated but was not considered statistical significant (confidence level as reported in original papers, generally 5% level).
