“…The global decline in biodiversity has driven calls for ambitious targets for biodiversity conservation and protected areas coverage (Peng et al, 2021). Thus, our findings could have a big impact on the conservation of biodiversity in drylands as the climate warms and causes more drought (Zhu et al, 2020;Jiao et al, 2021).…”

“…The drylands of China account for about 10.8% of the world's drylands, and China is the most drought-affected country in Asia (Huang et al, 2015). The dramatic increase in climate warming-driven drought is considered a potential threat to worldwide biodiversity (Dai, 2010;Jiao et al, 2021). Climate change may aggravate dryland degradation through the alteration of spatial and temporal patterns in temperature, rainfall, solar radiation, and winds, leading to vegetation degradation and ecosystem service loss in the drylands (Macheroum et al, 2021;Gul et al, 2022).…”

Environmental filtering (EF) and dispersal filtering (DF) are widely known to shape plant community assembly. Particularly in arid and semi-arid mountainous regions, however, it remains unclear whether EF or DF dominate in the community assembly of different life forms or how they interact along elevational gradients. This research aims to reveal how different ecological processes influence herbaceous and woody community assembly and how they respond to various environmental drivers and elevational gradients. Here we integrated taxonomic diversity (TD), phylogenetic diversity (PD), and ecological drivers across an elevational gradient of 1,420 m in the Helan Mountain Nature Reserve, in typical arid and semi-arid areas of China. This study showed that the TD and PD of herbaceous communities significantly increase linearly with changing elevation gradients, while woody ‘TD’ showed a unimodal pattern, and there was little relationship between woody ‘PD’ and elevation. Herbaceous species exhibited significant phylogenetic clustering at low elevations, where they were influenced by climate, aspect, and tree cover. However, woody species exhibited random patterns across elevations. Herbaceous and woody species’ taxonomic and phylogenetic beta diversity is governed primarily by spatial turnover rather than nestedness. Spatial turnover is caused primarily by EF and DF’s combined influence, but their relative importance differs between herbaceous and woody communities. Therefore, we conclude that the responses of herbaceous and woody plants along elevation gradients in the Helan Mountains are decoupled due to their different adaptation strategies to climate factors in the drylands. These findings are important for understanding the assembly mechanisms driving plant communities in dryland under the context of dramatic increases in drought driven by climate warming.

“…Moisture is a primary limiting factor for the radial growth of both B. platyphylla and B. costata. B. platyphylla, in particular, is affected by moisture conditions before the growing season (May to November), indicating moisture conditions have a hysteresis effect on ring width growth, leading to the influence being significant in the following year (Yu et al 2016;Jiao et al 2022;Li et al 2022). This agrees with a study on B. platyphylla from the Hanshan region of Inner Mongolia, China (Jia 2019), which found that moisture conditions of the previous year affected the growth of the birch in the current year.…”

Betula platyphylla and Betula costata are important species in mixed broadleaved-Korean pine (Pinus koraiensis) forests. However, the specific ways in which their growth is affected by warm temperatures and drought remain unclear. To address this issue, 60 and 62 tree-ring cores of B. platyphylla and B. costata were collected in Yichun, China. Using dendrochronological methods, the response and adaptation of these species to climate change were examined. A “hysteresis effect” was found in the rings of both species, linked to May–September moisture conditions of the previous year. Radial growth of B. costata was positively correlated with the standardized precipitation-evapotranspiration index (SPEI), the precipitation from September to October of the previous year, and the relative humidity in October of the previous year. Growth of B. costata is primarily restricted by moisture conditions from September to October. In contrast, B. platyphylla growth is mainly limited by minimum temperatures in May–June of both the previous and current years. After droughts, B. platyphylla had a faster recovery rate compared to B. costata. In the context of rising temperatures since 1980, the correlation between B. platyphylla growth and monthly SPEI became positive and strengthened over time, while the growth of B. costata showed no conspicuous change. Our findings suggest that the growth of B. platyphylla is already affected by warming temperatures, whereas B. costata may become limited if warming continues or intensifies. Climate change could disrupt the succession of these species, possibly accelerating the succession of pioneer species. The results of this research are of great significance for understanding how the growth changes of birch species under warming and drying conditions, and contribute to understanding the structural adaptation of mixed broadleaved-Korean pine (Pinus koraiensis) forests under climate change.
