    Abstract In early spring, because the tree and shrub layers are still dormant, the absorption of nutrients by herbs is the key factor to maintain nutrients in temperate forest ecosystems, but it is not clear whether climate change will change the nutrient uptake strategy of herbs. Therefore, we measured the biomass, fine root morphology, and stoichiometry of five dominant herbs in response to environmental changes in early spring in a temperate forest in northeastern China. The results showed that (1) Fine root morphology had strong plasticity. Under nitrogen addition treatment, the herbs tended to change the fine root length to absorb soil nutrients and water. (2) Under drought treatment, the herbs distributed more biomass to the belowground. Maintaining a higher root-shoot ratio might increase the relative supply of water to the herbs. (3) Nitrogen addition significantly decreased the belowground biomass allocation, but increased the ratio of belowground nitrogen to phosphorus (N:P) and the root metabolic activity. (4) Ephemeral herbaceous fine root morphology was more sensitive to water and nitrogen than other herbaceous plants. Collectively, in the context of climate change, early spring herbs may respond to environmental pressure through self-regulation and change growth strategies in temperate forest ecosystems.

    Abstract In order to study the response of fine root production (FRP), mortality (FRM) and turnover (FRT) to nitrogen (N) addition, we have conducted 12 years of continuous N addition experiments in the natural secondary forest in Northeast China. According to the local N deposition, three N treatments were set up. The response of FRP, FRM and FRT to N addition during the growing season was studied. The results showed that N addition would lead to phosphorus (P) limitation, and fine roots could increase the absorption of N and P by increasing their diameter. The increase in the diameter of fine roots led to a decrease in the FRT, and the soil layer also affected the FRT. Nitrogen addition increased the FRP and FRM in all soil layers. Nitrogen addition did not change the seasonal variation of FRP and FRM. The highest value of FRP occurred in May, and the lowest value of FRM occurred in August. Nitrogen addition increased the total number (TNLR) and surface area (TSALR) of live fine root in all soil layers. The TNLR and TSALR decreased with the deepening of soil layer. Collectively, fine roots may respond to environmental stress through self-regulation and changing growth strategies.

    Abstract Secondary forest succession after clear‐cutting is one of the foremost ecosystem restoration strategies, while soil microbes play essential roles in the processes by modulating nutrient cycling. However, the assembly processes and driving factors of soil microbial communities across secondary forest succession remain unclear. Here, we studied the assembly processes of soil microbial communities and examined shifts in soil microbial community‐associated functional dynamics across secondary forest succession. Our results showed that the stochastic process was more important in shaping bacterial community assembly throughout the successional process [modified stochasticity ratio (MST) > 50%], while the fungal community assembly was initially governed by deterministic processes (MST < 50%), but there was a progressive increase in stochastic selection as succession proceeded. Soil organic carbon and pH were principal factors for the explanation of changes in the bacterial community structure (total explained 43% change), and tree richness and productivity were principal factors for the explanation of shifts in the fungal community structure (total explained 17% change). The relative abundance of nitrogen transformation and saprotroph functional groups increased gradually with succession, whereas ectomycorrhizal fungi significantly declined. The results suggested that microbial community succession might accelerate the soil carbon and nitrogen turnover rates. Used together, the mechanisms shaping fungal and bacterial community structure are different in secondary forest succession and highlight that those fungi and bacteria are primarily controlled by plant traits and soil properties, respectively. Variations in microbial functional groups provide new insight into the mechanisms underlying the soil microbe‐driven soil nutrient cycles during secondary forest succession.

    Abstract BACKGROUND: Natural abundance of carbon (C) and nitrogen (N) stable isotope ratios (δ¹³C and δ¹⁵N) has been used to indicate the state and cycle of ecosystem C and N. However, it is still unclear how C and N cycle of boreal forests respond to the N deposition. RESULTS: We conducted an 8-year continuous N addition field experiment in a Larix gmelinii forest in Greater Khingan Mountains, Northeast China. Four N treatments (0, 25, 50, 75 kg N ha⁻¹ year⁻¹) were built. The effects of N addition on the δ¹³C and δ¹⁵N of needle, branch, bark, and fine root of Larix gmelinii and soil were studied. The result of the balance between the N input and output flux showed that N addition significantly increased the δ¹⁵N in each organ of Larix gmelinii, but did not change the δ¹⁵N of soil. We also found that the N absorption by needles of Larix gmelinii could increase the needle photosynthesis rate and δ¹³C by increasing carboxylation, but N addition had no significant effect on the δ¹³C of soil and other organs. In addition, both the soil δ¹⁵N and δ¹³C increased with the soil depth. CONCLUSIONS: Long-term N addition may lead to more open C and N cycles and further affect plant nutrient acquisition strategies in boreal forest ecosystems.

    Abstract: A long-term field litterbag manipulation experiment was conducted to examine the effects of reduced precipitation (−30% of through-fall), nitrogen (N) addition (50 kg N·ha⁻¹·yr⁻¹), and their combination (−30% of through-fall and 50 kg N·ha⁻¹·yr⁻¹) on the ...

    Abstract A long-term field litterbag manipulation experiment was conducted to examine the effects of reduced precipitation (−30% of through-fall), nitrogen (N) addition (50 kg N·ha⁻¹·yr⁻¹), and their combination (−30% of through-fall and 50 kg N·ha⁻¹·yr⁻¹) on the release and immobilization of N and phosphorus (P) in four litter types (Pinus koraiensis (PK), Tilia amurensis (TA), Quercus mongolica (QM), and their mixture (MIX)). The results showed that N addition did not significantly stimulate litter decomposition, whereas precipitation reduction and the interaction significantly inhibited litter decomposition. N immobilization was significantly enhanced by N addition and reduced precipitation in the PK, QM, and MIX litters but was significantly inhibited in the TA litter. N addition, reduced precipitation, and their combination significantly increased the final P concentration of the litter in each sampling period. Furthermore, interestingly, there was a significant exponential correlation between the remaining N and final P concentration in the PK litter and a significant linear correlation for the QM and MIX litters, but no significant correlation for the TA litter, indicating that the dynamic relationship between the remaining N and final P concentration in the litter depended on the litter type. These results suggest that the forest litter layer may alleviate the effects of N deposition by increasing litter N immobilization and aggravating soil P limitation by inhibiting litter P release following N deposition. Reduced precipitation may further affect biogeochemical cycles by inhibiting the release of litter N and P.

    Abstract Fine roots (< 2 mm in diameter) are the main organ for obtaining resources from the belowground part of forest and also act as a hub linking the ecological processes of plant and soil. However, in the context of global climate change, it remains unclear how fine root dynamics and morphology in temperate forests respond to increased nitrogen deposition and reduced precipitation in growing season on a year-round time scale. In this study, the minirhizotrons were used to observe the response of fine root dynamics (production, mortality, turnover and life span) and morphology (diameter, single root surface area, single root length) to long-term nitrogen addition (N, 50 kg N ha⁻¹ yr⁻¹), precipitation reduction (W, −200 mm yr⁻¹) and their interactive treatments (NW) in a broad-leaved Korean pine forest in Changbai Mountains over a two-year period. The results showed that N significantly increased the average diameter of fine roots. Compared to the control treatment, all treatments significantly reduced the average monthly number and surface area of live root. However, the morphological traits of the individual root in each treatment differed between the growing and non-growing seasons. All three treatments (N, W, NW) reduced annual production of fine root over the two observation periods, while the effect on annual mortality varied between years. N, W and the interaction of NW did not significantly change the annual turnover of fine root in the first observation period but increased significantly in the second. The median life span of fine root born in both non-growing seasons was significantly lower than that of fine root born in the growing season. Our results show that changes in the growth strategy of fine root depend on the complex interrelationship between their own morphology, soil layer and seasonal climatic conditions.

    Abstract Elevated nitrogen (N) deposition is changing soil communities around the world and will have unknown consequences for terrestrial ecosystem functions. In this study, we investigated a field experiment that lasted for 13 years to explore the effect of simulated N deposition and seasonal variations on the soil faunal community structure in a temperate natural secondary forest. The experimental design included a control group (0 kg N ha⁻¹ yr⁻¹, CK), low N addition (25 kg N ha⁻¹ yr⁻¹, LN), and high N addition (50 kg N ha⁻¹ yr⁻¹, HN). The results showed that long-term high N addition reduced the soil pH, C/N ratio, and microbial biomass carbon (MBC) and increased the total phosphorus. The soil faunal community structure after high N addition was significantly different from those after the CK and low N addition treatments. The overall trend was that abundance and richness increased under low N addition and decreased under high N addition. Further analysis showed that the abundance of omnivores and detritivores was lowest after high N addition, significantly less than the CK and low N addition. The interaction of N addition and seasonal dynamics had a significant impact on herbivores. We found that these changes were driven by differences in ecological strategies such as food and environmental preferences. Furthermore, temperature, moisture, nutrients, and pH in the soil environment were the key factors driving ecological strategies and environmental factors. Seasonal variations significantly affected the soil faunal community structure, showing the highest abundance, richness, diversity, and functional group abundance and richness of the soil faunal community in September. Nitrogen addition and seasonal dynamics significantly affected the abundance and richness of soil fauna by changing soil nutrient concentrations, MBC, and plant diversity. Our study showed that long-term high N addition reduced the abundance and functional group abundance of the soil fauna in natural secondary forests, while low N addition had a positive effect on soil faunal community structure. Collectively, the results suggest that the seasonal balance of soil fauna is affected after long-term N addition, which increases the seasonal sensitivity of soil fauna.

    Abstract The continuous increase in global atmospheric nitrogen deposition may change the stoichiometric balance of temperate forest plants and affect the nutrient absorption of plants and the carbon and nitrogen cycle of forests. Leaf, fine root and other ephemeral tissues are very sensitive to nutrient changes. However, it has been not clear whether nitrogen addition will affect the nutrient uptake strategies of plant leaves and fine roots. In order to explore the effects of long-term nitrogen addition on nutrient absorption and distribution of main dominant tree species in temperate secondary forests and to cope with the sustainable development of forests under the background of increasing atmospheric nitrogen deposition in the future, we conducted a 12-year continuous nitrogen addition experiment in the natural secondary forest in Changbai Mountains of Northeast China. Responses of fine root morphology, leaf nutrient resorption, fine root exudates and stoichiometry of Populus davidiana and Betula platyphylla to nitrogen addition were studied. Our study found that (1) nitrogen addition could lead to phosphorus limitation, and high nitrogen addition treatment significantly reduced the nitrogen resorption efficiency of B. platyphylla and P. davidiana and then increased the phosphorus resorption efficiency. (2) Nitrogen addition promoted the metabolism and activity of B. platyphylla fine root, which was more inclined to transport and store, while P. davidiana fine root was more inclined to capture and absorb nutrients. (3) Nitrogen addition increased the secretion rate of fine root exudates carbon and decreased that of fine root exudates nitrogen. The release of root exudates from roots to soil may stimulate soil microbial activity and nutrient availability. These different results indicate that both P. davidiana and B. platyphylla are attempting to improve resource acquisition under nitrogen deposition change, which will effectively change the soil carbon and nitrogen cycle of temperate forests.

    Abstract As a microbial-derived carbon (C) compound, the glomalin-related soil protein (GRSP) is not only a considerable amount of soil active organic C, but also an effective aggregate binder. At present, due to various global change factors, the forest ecosystem C stock and soil stability are facing unprecedented challenges. As the two of important global change factors, the effects of increased nitrogen (N) deposition, precipitation pattern change and their interaction on the soil organic C (SOC) stock, aggregate stability and GRSP and their correlations are not clear. Based on this, we conducted a long-term field experiment in a temperate forest to simulate N addition and precipitation reduction (n = 3). The experimental design included a control, decreased precipitation (DP), N addition (+N) and their interaction (+N×DP). Compared with the control, the negative effect of N addition on the total GRSP (T-GRSP) was not significant, but it significantly reduced the easily extractable GRSP (EE-GRSP) and mean weight diameter (MWD) (P < 0.05). The T-GRSP, EE-GRSP and MWD all showed significant negative responses to the DP treatment (P < 0.05). Compared with the single treatment, the +N×DP treatment further strengthened the negative effects on the EE-GRSP and MWD (P < 0.05). In addition, we found that the MWD was mainly controlled by large aggregates (>2 mm), and the DP and +N×DP treatments destroyed the seasonal stability of aggregate. The correlation analysis showed that the T-GRSP had a strong correlation with the SOC, while the EE-GRSP had a more significant correlation with the MWD (P < 0.001). Through this study, we emphasized the profound impact of global change factors on temperate forest, clarified the ecological functions of the T-GRSP and EE-GRSP, and confirmed the reciprocal mechanism of the GRSP, SOC and MWD. Collectively, our results will be helpful to evaluate the impact of climate change on forest ecosystems from the perspective of microbial derivatives.
