“…The type of tree species has a profound effect on SOC stock changes since tree litterfall and roots are the main sources of SOC inputs. Both the quantity and quality of litter and living roots are related to tree traits (Gill and Jackson 2000;Cornwell et al 2008;Kooch et al 2019;Olsson et al 2019;Cao et al 2020). The rate of SOC stock change of deciduous broadleaved trees is significantly higher than that of sempervirent broadleaved and conifer trees in the 0-20 cm soil depth (Fig.…”

“…Tree types play an important role in SOC stock changes after afforestation, because forest litter (aboveground and belowground) is a major component of soil organic matter input (Gill and Jackson 2000;Cornwell et al 2008;Olsson et al 2019). Different tree types not only have different litter production, but their litter decomposition rates also differ (Cao et al 2020) and both contribute to SOC stock change dynamics.…”

“…Broadleaved litter is faster decomposable than coniferous litter because the former contains less lignin (Lukac and Godbold 2011). The litter decomposition rate is also related to the form and structure of the foliage (Olsson et al 2019). Litterfall of sempervirent trees generally decompose more slowly than that of deciduous trees (Cornwell et al 2008).…”

& Key message Different tree species have dissimilar capacities to sequester soil organic carbon (SOC). Deciduous broadleaved trees show the most stable increase in SOC stock after afforestation than other tree species, while sempervirent conifer trees show the lowest rate of SOC stock change. Sempervirent broadleaved trees show the greatest increase in SOC stock 20 years after afforestation. & Context The rate at which soil organic carbon (SOC) stock changes after afforestation varies considerably with the tree species. A better understanding of the role of tree species in SOC change dynamic is needed to evaluate the SOC sequestration potential of afforestation programs. & Aims The aim of this paper is to identify the dissimilar rates at which different tree species sequester SOC, following afforestation. & Methods We complete a meta-analysis with 544 data points from 261 sites in 90 papers. We group tree species into decidious broadleved, sempervirent broadleaved and sempervirent conifer. We use standardization and/or extrapolation methods to standardize soil depths. Statistical analysis test the main effects of tree species and their interactions with previous land use and plantation age on SOC stock change after afforestation. & Results Deciduous broadleaved trees show a stable increase in SOC stock, and are especially suited for afforestation of grassland or soils with high initial SOC. Sempervirent broadleaved afforestation results in loss of SOC stock in young stands, but greater SOC stock in mature stands. Sempervirent conifer trees show the lowest rate of SOC stock change, but are suitable for nutrient-poor soil. & Conclusion The results emphasize the importance of considering tree species when estimating SOC stock change, in particular when carbon sequestration is an objective of afforestation programs.

“…The present study mainly focused on assessing the growth, photosynthesis and micropropagation of three species (E. cloeziana, E. umbellata and E. benthamii). [15][16][17][18] To the best of our knowledge, the biological activity of Eucalyptus EOs has not been reported, based on our continuous interest [19,20] in Eucalyptus oil, we report the repellent, insecticidal and antimicrobial activity of three Eucalyptus EOs.…”

Developing effective and eco‐friendly antimicrobials and pesticides has become a highly important issue. The repellent, insecticidal and antimicrobial activity of essential oils (EOs) isolated by hydrodistillation from dried leaves of the three Eucalyptus species (E. cloeziana, E. umbellata and E. benthamii) were investigated. During GC/MS analysis, α‐pinene (47.36 %), 1,8‐cineol (38.53 %) and α‐pinene (35.31 %) were identified as major components of E. cloeziana, E. umbellata and E. benthamii, respectively. The EOs from E. cloeziana exhibited the longest effective protection time (465 min, at 50.0 % w/w) for humans among the EOs studied. The effective protection time was 30 min and 300 min at concentrations of 12.5 % (w/w) and 25.0 % (w/w), respectively. Fumigating insecticidal activity of EOs from three Eucalyptus species was tested by airtight fumigation in conical flask, which indicated that essential oils had a highly and rapidly insecticidal activity on Culex pipiens quinquefasciatus. The antimicrobial activity of EOs was evaluated by using disc diffusion and agar dilution methods. There was no significant difference in the antibacterial activity of EOs from E. cloeziana and E. umbellate and they had the same MICs (20 mL/L) on Staphylococcus aureus, Salmonella typhi, Bacillus subtilis and Escherichia coli. E. benthamii had the worst microbial inhibitory effect among the three Eucalyptus essential oils and the MIC value for the test species is 40 mL/L except for Rhodotorula Harrison (10 mL/L).

“…Scholars have carried out a large number of studies on the ecological functions of forest litter in China and in other countries, mainly focusing on the litter storage (Ge et (Innangi et al 2018). With the deepening of research on litter ecology, an increasing number of experts and scholars in the elds of ecology, forestry, geochemistry, and environmental science have focused on litter function (Xiao and Guan, 2018;Quadros et al 2019;Olsson et al 2019;Faust et al2019). At present, research on the hydrological functions of litter in China has mainly focused on the effects of different vegetation types Tu et al 2019), site conditions (Zhao et al 2018;Zhang et al 2019), and disturbance and intensity (Liu.…”

Taking the litter layer of three typical plant communities (broad-leaved forest, coniferous forest, and shrubs) as the research object, this study analyzed the hydrological function characteristics of the litter layers of different typical plant communities using the indoor immersion method in order to reveal the effects of the traits of the litter layer on the hydrological functions of typical plant communities in the core area. The results showed that: (1) the litter reserve change trend decreased in order as follows: broad-leaved forest (13.31 ± 1.54 t/hm2) > shrubs (12.62 ± 2.34 t/hm2) > coniferous forest (11.36 ± 1.43 t/hm2). The coniferous forest and shrub litter reserves increased significantly with the increase of decomposition degree (F = 19.36, P < 0.01; and F = 9.19, P < 0.01, respectively), while the broad-leaved forest litter reserves decreased first and then increased significantly with the increase of decomposition degree (F = 25.70, P < 0.01); (2) the litter natural moisture content change trends were as follows: shrubs (34.09 ± 4.31 t/hm2) > broad-leaved forest (31.32 ± 1.76 t/hm2) > coniferous forest (29.48 ± 7.02 t/hm2). The change trends of the maximum water-holding capacity, maximum interception amount, maximum interception rate, effective interception amount, and effective interception rate were in descending order as follows: broad-leaved forest > shrubs > coniferous forest. The maximum water-holding capacity, maximum interception amount, and effective interception amount of litter rose with the increase of decomposition degree. The broad-leaved forest community litter layer had the strongest rainfall interception function and the best hydrological service functions. The interception function was stronger with the increase of the decomposition degree of the litter layer; (3) the water-holding and water-releasing capacity variation of the litter layers manifested as reversed “J” features for the three typical plant communities. The water-holding capacity of different plant community litter layers (Qct) was significantly positively correlated with time (t) (P < 0.01), and the equation was Qct = b + alnt, whereas the water-releasing capacity of different plant community litter layers (Qst) was significantly positively correlated with time (t) (P < 0.01), and the equation was Qst = a t b; and (4) the water absorption and release rates of the litter layers had four periods. The water absorption rate (v) was significantly negatively correlated with time (t) (P < 0.01), and the equation was v = a t− b, while the water release rate was the same. The water absorption and release rates differed by one order of magnitude in the first 5 min, exhibiting the greatest regulation and storage function, while the rate differed by only 2.1–4.5 times during the last three periods. This shows that the litter layer has the strongest rainfall regulation and storage function for only a short period of time before declining.
