“…Supporting our hypothesis II, we found W + IP and W + DP affects plant phenology in synergistic and antagonistic ways, respectively (Figure 3). Warming helped to meet the accumulative temperature requirements earlier (Cooke et al, 2012; Lang, 1987), while increased precipitation not only supplied enough water required for onset of plant growth and reproductive phenophases but also prevented plants from experiencing a concurrent water deficiency induced by warming (Yan et al, 2021). In addition, low temperatures limit the water absorbed by roots (Alvarez‐Uria & Körner, 2007), and warming induces an earlier water uptake (Lupi et al, 2012) and smooth water transport by trunk sap flow (Repo et al, 2008), further stimulating the sequential mobilization of the transport of mineral nutrients (De Barba et al, 2016; Li et al, 2022) and hormones (Lyr, 1996).…”

Shifts in plant phenology influence ecosystem structures and functions, yet how multiple global change drivers interact to affect phenology remains elusive. We conducted a meta-analysis of 242 published articles to assess interactions between warming (W) and other global change drivers including nitrogen addition (N), increased precipitation (IP), decreased precipitation (DP) and elevated CO 2 (eCO 2 ) on multiple phenophases in experimental studies. We show that leaf out and first flowering were most strongly affected by warming, while warming and decreased precipitation were the most pronounced drivers for leaf colouring. Moreover, interactions between warming and other global change drivers were common and both synergistic and antagonistic interactions were observed: interactions W + IP and W + eCO 2 were frequently synergistic, whereas interactions W + N and W + DP were mostly antagonistic. These findings demonstrate that global change drivers often affect plant phenology interactively. Incorporating the multitude of interactions into models is crucial for accurately predicting plant responses to global changes.

“…Our results therefore did not support H2, and suggested that an advance in autumn senescence due to earlier spring phenology would not offset warming-induced delay. Warming could slow down the process of chlorophyll degradation and breakdown, thereby leading to the delay in autumn senescence Shi et al, 2014;Yan et al, 2021). The delay of autumn senescence (i.e.…”

The Tibetan Plateau holds the world's largest alpine permafrost and is undergoing an acceleration of warming. Phenological shifts over alpine permafrost in a warmer world have been little studied and are greatly underrepresented in current syntheses. Here, we conducted seasonal and gradient temperature‐controlled experiments in a permafrost‐affected meadow to evaluate how warming drives shifts in spring and autumn phenology, and associated growing‐season length at both community and species levels. We found that there is no sign of slowdown in spring advance with warming under a higher year‐around warming treatment, aligning with a future medium warming scenario. Although spring advance led to an advance in autumn senescence according to spring‐only warming experiments, the advance could not offset the delay due to concurrent warming. As a result, year‐around warming significantly delayed autumn senescence, although there was a deceleration in delay with warming under high temperature treatment than under the low one. This finding can be attributed to the possibility that winter warming is insufficient to reduce chilling accumulation, which would not delay spring phenology and then lead to a non‐slowdown in spring phenological advancement. Taken together, there is no slowdown in an extension of growing season length with warming under a higher year‐around warming treatment, with an increase of length by 9 and 21 days at the end of this century under a CO2 stabilization and medium warming scenarios, respectively. Synthesis. Our results suggest that a continued growing season extension at least under the medium warming scenario would help permafrost‐affected meadow ecosystems to mitigate permafrost carbon release on the Tibetan Plateau.

“…Plant phenology is an annual pattern of plant developmental stages that is sensitive to environmental changes (CaraDonna et al, 2014; Cleland et al, 2006; Sherry et al, 2007). Given that nitrogen (N) and water are two critical factors for plant growth and survival (Yan et al, 2021; Yang et al, 2011), widespread N enrichment (Wang & Tang, 2019; Xia & Wan, 2013) and changing precipitation patterns (Shen et al, 2015, 2022) by anthropogenic activities (IPCC, 2014) could alter plant phenology. The Tibetan Plateau is considered to be a major driver and amplifier of local and global climate change (Chen et al, 2013; Ma, Collins, et al, 2020), and it has experienced widespread N enrichment (Mao et al, 2020) and altered precipitation patterns (Lin et al, 2022; Ma, Lu, et al, 2020) during the second half of the 20th century, which will continue to change in the future (Li et al, 2020).…”

Different responses of functional groups to N addition increased synchrony and shortened community reproductive duration in an alpine meadow

Flowering and fruiting phenology of plants is sensitive to environmental cues, and changes in reproductive phenology of individual plant species under climate change have been widely reported. However, how species‐level phenological responses scale up to affect community‐level reproductive phenology patterns (synchrony and reproductive duration) are still unclear. An experiment on the effects of nitrogen (N) addition and precipitation changes on reproductive phenological traits of 52 species was conducted in an alpine meadow on the eastern Tibetan Plateau to determine the influence of the phenological response in different functional groups on community‐level reproductive phenology. N addition significantly delayed the onset date of reproductive phenology of sedges (early‐flowering species) and advanced the end date of reproduction of forbs (late‐flowering species). Meanwhile, N addition reduced the number of individuals involved in reproduction of sedges and forbs, but it increased that of grasses (late‐flowering species). Furthermore, N addition increased reproductive synchrony, delayed the onset and shortened the duration of reproductive phenology at the community level. However, precipitation changes and their interaction with N addition had no significant effect on reproductive phenology of the alpine plant community. Synthesis. These results suggested that differences in the direction and magnitude of response of different species to N enrichment lead to compression of reproductive duration at the community level, increasing the degree of overlap between reproductive events, which could change future species diversity, trophic interactions and productivity accumulation in alpine meadows on the Tibetan Plateau. Overall, knowledge of phenological responses from plant functional groups to the community level contributes to robust prediction and mechanistic understanding of community structure and function in response to future climate change.

Divergent responses of phenology and growth to summer and autumnal warming

Abstract: The surface air temperature over land during 2006-2015 has increased by 1.53°C since the period 1850-1900 and is predicted to increase further (IPCC, 2019). Global warming has greatly influenced ecosystem processes (
