Changes in tree growth synchrony and resilience in Siberian Pinus sylvestris forests are modulated by fire dynamics and ecohydrological conditions

•Growth synchrony patterns of Siberian Scots pine populations are driven by climate.•Growth synchrony in sites with mineral soil has increased but decreased in peats.•High fire occurrence reduced synchrony in frequently burned sites since mid-1980s.•Growth suppressions allow reconstructing past fire occurrence.•Post-fire legacies last from 1-5 years depending on soil type, fire and tree features.
