“…According to the “stress gradient hypothesis,” biotic communities tend to be simplified and homogenized for adapting to high levels of environmental stress, which greatly reduces the interspecific competition and niche differentiation (Bertness & Callaway, 1994; Hernandez et al, 2021; Maestre et al, 2009). For instance, diversified plant communities are likely converted to be simplified and homogenized communities dominated by a few dominant species along the increasing aridity gradient, such as Stipa purpurea or S. glareosa (Wu et al, 2014; Zhao et al, 2018). Even if the diversity of plant community continues to decline, the dominant species can partly maintain AGB and BGB under drought stress through a series of drought‐tolerant traits, such as increasing leaf rolling and the proportion of thick roots, accumulating compatible solutes and the abundance of antioxidant enzymes (Li et al, 2016; Zhang, Schellenberg, et al, 2018; Zhang, Wang, et al, 2019).…”

“…It is quite perplexing that 1.0×10 4 km 2 of S. bungeana grassland in the Tibetan Plateau disappeared entirely in just the past 50 a (Zhao et al, 2018). Besides those areas occupied by reclamation and building land, 80% of this grassland was displaced by a shrub-grassland continuum dominated by A. wellbyi and T. bromoides.…”

“…However, this classification was mainly based on expert opinion, community distribution ranges and ecological context but not on a plot data-based numerical analysis. Only a few studies have investigated the community characteristics of a small number of Stipa steppe alliances and conducted an association classification based on dominant species (Yang et al 2014;Qiao et al 2017aQiao et al , b, 2020Zhao et al 2018;Zhu et al 2018;Lu et al 2020). Moreover, some Stipa species are very similar and hard to distinguish.…”
