“…The surface litter layer served as a source of monoterpenes, with emissions (109.09 ± 41.75 ng g −1 h −1 ; Figure 3A) around one-tenth of the emission factor (1.02 ± 0.65 μg g −1 h −1 ; Zeng et al, 2022a) of E. urophylla reported in subtropical China. This contrasts with previous results from tropical and subtropical soils, where the presence of surface litter did not affect soil monoterpene exchanges (Huang et al, 2021;Llusià et al, 2022), although the emitted monoterpenes may hardly escape from the litter-soil layer due to higher soil uptakes of monoterpenes in this study. However, upward fluxes may occur when a large amount of litter (especially leaf litter, see below) covers the soil surface, leading to monoterpene production in the surface litter layer that exceeds soil uptakes of monoterpenes.…”

“…This contrasts with the decrease in the observed rate of isoprene uptake from temperate forest soils at high temperature (>30°C, Cleveland and Yavitt, 1998). The significant negative linear correlation between monoterpene fluxes and soil temperature was consistent with results found in subtropical pine and broad-leaved forest soils (Huang et al, 2021) and temperate forest soils (Trowbridge et al, 2020). However, significant correlations of soil temperature with monoterpenes and sesquiterpenes contrast with the finding that neither terpene group correlated with soil temperature in tropical forest soils (Llusià et al, 2022).…”

“…The isoprenoid fluxes were generally not correlated with soil moisture in this study (Figures 4,5), and the lack of association for soil monoterpene fluxes was also found in previous studies conducted in subtropical forests (Huang et al, 2021). Similarly, Llusià et al (2022) reported weak associations between the exchanges of monoterpenes (r = 0.45, p < 0.01) and sesquiterpenes (r = −0.38, p < 0.01) and soil moisture in tropical forest soils.…”

“…Previous studies focused on temperate and boreal regions (Asensio et al, 2007b,c;Mäki et al, 2019a,b), with limited research in tropical and subtropical forests. Soil BVOC fluxes in these regions remain inconsistent, requiring more data to improve modeling and ecosystem understanding (Bourtsoukidis et al, 2018;Huang et al, 2021;Llusià et al, 2022). Subtropical China, characterized by ideal tree growth conditions, has plantation forests lacking BVOC flux information.…”

The exchange of isoprenoids, which includes isoprene, monoterpenes, and sesquiterpenes, between ecosystem soils and the atmosphere plays a significant role in soil ecology and atmospheric chemistry. However, research on flux exchange rates in subtropical ecosystems has been limited, as previous studies have mainly focused on temperate and boreal environments. In this study, we aimed to quantify the exchange of isoprenoids between the soil (with or without surface litter) and the atmosphere in a subtropical Eucalyptus urophylla plantation forest during the daytime in the wet season of subtropical China. Additionally, we investigated the influence of soil and litter variables on the fluxes of isoprenoids. Our results unveiled the exchange of isoprene and 17 terpenoid compounds, comprising 11 monoterpenes and 6 sesquiterpenes, between the studied soils and the atmosphere. Interestingly, regardless of the presence of surface litter, the studied soils acted as net sinks for isoprenoids, with isoprene being the most absorbed compound (−71.84 ± 8.26 μg m−2 h−1). The removal of surface litter had a significant impact on the exchange rates of two monoterpenes (α-pinene and β-pinene), resulting in decreased fluxes. Furthermore, the exchange rates of isoprene were positively correlated with litter dry weight and negatively correlated with soil temperature. The higher exchange rates of monoterpenes and sesquiterpenes were associated with increased levels of soil respiration and the abundance of leaf litter. These findings suggest that, in the context of projected global warming scenarios, the capacity of subtropical soils to act as sinks for isoprenoids is expected to increase in subtropical China. These changes in sink capacity may have implications for regional-scale atmospheric chemistry and ecosystem functioning.

“…Across major terrestrial ecosystems worldwide, high N inputs may lead to variation in soil nutrient availability and soil acidification, which then can drive changes in plant species diversity and community composition (Bobbink et al, 2010; Payne et al, 2017). In China, high N deposition rates to forest ecosystems have resulted in soil acidification (Liu et al, 2011), plant biodiversity loss (Liu et al, 2013), carbon storage changes (Gu et al, 2015), changes in fluxes of greenhouse gases and increased susceptibility to environmental stresses (Huang et al, 2021; Liu et al, 2011). In contrast, the effects of N deposition on soil fauna have been less explored, especially ground‐dwelling fauna (Gan et al, 2014).…”

1. While it is clear that nitrogen (N) deposition impacts the plant diversity of major terrestrial ecosystems, how ground-dwelling fauna respond to N deposition is less understood.2. Here, we use a novel experimental methodology of canopy addition of N (CAN) to simulate realistic N deposition and contrast this method to standard understory addition of N (UAN) in a temperate forest and a subtropical forest. We investigated the shifts in community composition and trophic position for ground-dwelling spiders under different N deposition treatments.3. We found that the CAN deposition treatment increased the diversity of sit-andwait spiders and the abundance of actively hunting spiders at the subtropical forest, but N treatments had no effect on spider abundance or diversity at the temperate forest. In contrast, UAN treatments had no significant impact on spider communities compared to control treatment. Furthermore, N treatments had significant effects on spider assemblage at subtropical forest. Overall, spiders in the CAN treatment had a higher trophic position as indicated by δ 15 N isotopic signatures at both forest types. 4. In conclusion, our study suggests that the effects of N deposition on grounddwelling spider assemblages depend on N addition approaches. Furthermore, our results suggest that CAN is a more realistic method for understanding the effects of atmospheric N deposition on soil arthropods in forest ecosystems.
