“…For example, considerable differences and debate exist in start of growing season (SOS) trends on the Qinghai-Tibet Plateau in the early twentieth century, where permafrost was extensive (Shen et al, 2011(Shen et al, , 2013(Shen et al, , 2014(Shen et al, , 2022(Shen et al, , 2022(Shen et al, , 2022Piao et al, 2011;Wang et al, 2017;Yu et al, 2010;Zhang et al, 2013). Less attention has focused on the end of the growing season (EOS), even though it also plays a crucial role in carbon and nutrient cycling in terrestrial ecosystems (Park et al, 2019) and, compared to SOS, the physiological process of plant senescence is more complex (Li & Ren, 2023). EOS phenology is more difficult to accurately portray, the extent to which EOS change is already underway remains unclear (Liu et al, 2016;Wu et al, 2017).…”
