Long-term changes in the impacts of global warming on leaf phenology of four temperate tree species (original) (raw)

2018, Global change biology

Contrary to the generally advanced spring leaf unfolding under global warming, the effects of the climate warming on autumn leaf senescence are highly variable with advanced, delayed, and unchanged patterns being all reported. Using one million records of leaf phenology from four dominant temperate species in Europe, we investigated the temperature sensitivities of spring leaf unfolding and autumn leaf senescence (S , advanced or delayed days per degree Celsius). The S of spring phenology in all of the four examined species showed an increase and decrease during 1951-1980 and 1981-2013, respectively. The decrease of the S during 1981-2013 appears to be caused by reduced accumulation of chilling units. As with spring phenology, the S of leaf senescence of early successional and exotic species started to decline since 1980. In contrast, for late successional species, the S of autumn senescence showed an increase for the entire study period from 1951 to 2013. The impacts of rising temp...
