“…In addition, CWM_Ht was found positively controlled by SWC, and it further improved the EMF (Figure 5A). Plant height is generally related to light resource acquisition, and so a higher CWM_Ht can increase the accumulation of aboveground biomass, and accordingly soil carbon and nitrogen storage (De Deyn et al, 2008;Zuo et al, 2016;Wang et al, 2021). The positive effect of CWM indices on multifunctionality supports the mass ratio hypothesis, which posits that ecosystem functions are mainly determined by the most abundant species in a given community (Grime, 1998).…”

The relationship between biodiversity and ecosystem multifunctionality (EMF) is crucial for understanding the processes of ecological restoration in semi-arid regions. However, partitioning the relative influence of various biodiversity attributes, namely taxonomic, functional, and phylogenetic diversity, on EMF during secondary succession is still unclear. This study aimed to bridge the gap by employing field measurements and the chronosequence approach at 21 plots with different stand ages and precipitation conditions on the Loess Plateau of China. For diversity indices, we calculated the Shannon–Wiener diversity index, Simpson’s dominance index, Pielou evenness index, community weighted mean (CWM), functional variance (FDvar), and Faith’s phylogenetic diversity (PD) based on the empirically measured composition and traits of plant species. The EMF was expressed as the averaged value of eight function variables (including aboveground biomass, root biomass, soil total carbon, total nitrogen, and total phosphorus content, soil organic carbon, available nitrogen and available phosphorus content). The results showed that species evenness and CWM of leaf dry matter content (LDMC) significantly increased yet the CWM of specific leaf area (SLA) decreased with stand age, indicating the resource-use strategy of the plants became more conservative through succession into its later stages. The EMF increased with both stand age and mean annual precipitation. The structural equation model revealed that stand age, soil water content (SWC), and the multiple diversity indices altogether accounted for 56.0% of the variation in the EMF. PD and the CWMs of plant height and LDMC had positive effects on the EMF, and the FDvar of leaf nitrogen had negative effects on EMF. However, the Shannon Wiener diversity had no significant effect on the EMF. Our results suggest that functional and phylogenetic diversity are more important than taxonomic diversity in predicting EMF, and that multidimensional biodiversity indices should be jointly considered to better predict EMF during the succession of semiarid grasslands.

“…Alterations in water and N availabilities associated with global change (e.g., changing precipitation regime and atmospheric N deposition) may accelerate or slow down the successional processes in plant communities directly through impacting recovery of plant growth and productivity after disturbance and indirectly by affecting species competition (Anderson‐Teixeira et al, 2013; Clark et al, 2019; Poorter et al, 2016; Seabloom et al, 2020). Increased precipitation can stimulate plant growth and the accumulation rate of aboveground biomass by enhancing soil water availability (Anderson‐Teixeira et al, 2013; Poorter et al, 2016; Wang et al, 2021). The enhanced plant productivity could provide more C substrate supply for root growth and soil microbial activity (Wan et al, 2007), and consequently increase soil respiration during secondary succession.…”

“…Secondary succession, a directional and predictable process of ecological community development following natural or anthropogenic perturbations (Odum, 1969), is primarily driven by disturbance legacy and inherent soil and vegetation characteristics (Estrada‐Villegas et al, 2020; Meiners et al, 2015). During natural succession, plant community composition and structure change over time (Clark et al, 2019; Isbell et al, 2019), which could influence primary productivity (Isbell et al, 2019) and litter quantity and quality (Yahdjian et al, 2017), with subsequent effects on soil carbon (C) processes (Wang et al, 2021; Yahdjian et al, 2017; Yang et al, 2019; Zhang et al, 2016). Soil respiration, consisting of autotrophic (from plant roots) and heterotrophic (from soil microbes and fauna) components, is the primary pathway of C emission from soil to the atmosphere and can largely determine terrestrial C balance (Schlesinger & Andrews, 2000; Song et al, 2019a).…”

“…Given the close relationships of soil C processes with plant growth and community dynamics (De Deyn et al, 2008; Yahdjian et al, 2017; Yang et al, 2019; Zhang et al, 2016), it is reasonable to expect that soil respiration may show temporal variations during secondary succession of plant communities. However, the majority of previous studies have only explored the dynamics of aboveground processes (e.g., recovery of plant community composition and aboveground biomass after disturbance; Isbell et al, 2019; Poorter et al, 2016; Wang et al, 2021), little attention has been paid to the temporal changes of soil C release in successional plant communities (Chen et al, 2021; Powers & Marín‐Spiotta, 2017).…”

Ecological succession after disturbance plays a vital role in influencing ecosystem structure and functioning. However, how global change factors regulate ecosystem carbon (C) cycling in successional plant communities remains largely elusive. As part of an 8‐year (2012–2019) manipulative experiment, this study was designed to examine the responses of soil respiration and its heterotrophic component to simulated increases in precipitation and atmospheric nitrogen (N) deposition in an old‐field grassland undergoing secondary succession. Over the 8‐year experimental period, increased precipitation stimulated soil respiration by 11.6%, but did not affect soil heterotrophic respiration. Nitrogen addition increased both soil respiration (5.1%) and heterotrophic respiration (6.2%). Soil respiration and heterotrophic respiration linearly increased with time in the control plots, resulting from changes in soil moisture and shifts of plant community composition from grass–forb codominance to grass dominance in this old‐field grassland. Compared to the control, increased precipitation significantly strengthened the temporal increase in soil respiration through stimulating belowground net primary productivity. By contrast, N addition accelerated temporal increases in both soil respiration and its heterotrophic component by driving plant community shifts and thus stimulating soil organic C. Our findings indicate that increases in water and N availabilities may accelerate soil C release during old‐field grassland succession and reduce their potential positive impacts on soil C accumulation under future climate change scenarios.
