“…Our results showed forest secondary succession altered the diversity of soil bacterial and fungal communities. This finding is in agreement with those of previous studies in temperate and subtropical forests [31,49]. In this study, the diversity of the soil bacterial community increased from the early to middle and late stages, while fungal community diversity was highest in the middle successional stage.…”

“…A previous study indicated that plant attributes (such as plant cover and functional traits) were also important factors affecting soil microbial communities [57]. In fact, the vegetation of middle successional stages contains more plant species because it includes both early and late successional stages [31]. With more plant species, more fungal species can coexist, which increases soil fungal community diversity.…”

“…The alpha diversity of soil bacterial and fungal communities in the three succession stages was compared using one-way ANOVA, including the number of OTUs (richness) and the Chao1 and Shannon indexes [43,44]. Additionally, nonmetric multidimensional scaling (NMDS), based on the Bray-Curtis dissimilarity matrices of OTUs of bacterial and fungal communities (Hellinger transformed), was used to test for differences in beta diversity using the "vegan" packages [31,43]. The NMDS analysis had certain reliability when Stress < 0.2.…”

“…However, there is accumulating evidence that soil abiotic properties and plant community characteristics are simultaneously important in regulating soil microbial communities [2,28,29]. The composition and diversity of tree species can directly affect the functions of soil microbial communities by altering the quantity and quality of resources [23,30,31]. It is thus necessary to find out the relations between the composition and diversity of soil bacterial and fungal communities, and plant diversity and soil properties, in order to predict the changes in soil microbial community structures during ecosystem development [8].…”

Soil microbial communities play an important role in maintaining the ecosystem during forest secondary succession. However, the underlying mechanisms that drive change in soil microbial community structures during secondary succession remain poorly defined in species-rich subtropical coniferous forests. In this study, Illumina high-throughput sequencing was used to analyze the variations in soil microbial community structures during forest secondary succession in subtropical coniferous forests in China. The role of soil properties and plant diversity in affecting soil bacterial and fungal communities was determined using random forest and structural equation models. Highly variable soil microbial diversity was observed in different stages of secondary succession. Bacterial community diversity rose from early to middle and late successional stages, whereas fungal community diversity increased from early to middle successional stages and then declined in the late stage. The relative abundance of Acidobacteria, Gemmatimonadetes, Eremiobacterota(WPS-2), Rokubacteria, and Mortierellomycota increased during succession, whereas the relative abundance of Ascomycota and Mucoromycota decreased. The community composition and diversity of the soil microbial community were remarkably influenced by plant diversity and soil properties. Notably, tree species richness (TSR) displayed a significant and direct correlation to the composition and diversity of both bacterial and fungal communities. The carbon-to-nitrogen (C:N) ratio had a direct impact on the bacterial community composition and diversity, and pH had a marked impact on the fungal community composition and diversity. Furthermore, succession stage and plant diversity indirectly impacted the composition and diversity of soil bacterial and fungal communities via soil properties. Overall, it can be concluded that soil intrinsic properties and plant diversity might jointly drive the changes in soil microbial community composition and diversity during secondary succession of subtropical coniferous forests.

“…The natural pastures of the studied area are actively used for haymaking. Over twenty years, in the absence of grazing livestock, the phytocoenosis of natural pastures has changed significantly, having gone through several stages [10], and began to play a key role in the formation of the soil fungal community. Even in the absence of grazing in the meadow, over time, there is a complete degeneration of good forage grasses, which are replaced by low-value and even fodder-harmful vegetation.…”

The paper presents data on the indicators of livestock production, the number of farm animals and poultry in the Tyumen region. The characteristics and significance of near-village forage lands are given. The studied forage lands are assigned to the forest-steppe lowland latitudinal-zonal area of the Kurgan province and contain valuable species of herbs: Calamagrostis epigejos, Bromopsis inermis, Festuca pratensis, Vicia villosa Roth, Trifolium rubens L., Medicago falcata. The territory of pastures is used for mowing and grazing animals of the individual sector, which prevents sodding and degeneration and has a significant impact on the consistent regular change of the biological community (phytocoenosis, microbial community, etc.). The hay yield is 14.7 c/ha, which corresponds to natural meadows without cultivation. To improve the quality of hay and yield, the authors suggest carrying out agrotechnical measures: compliance with the terms of mowing the grass - a week before flowering or at the beginning of flowering of meadow grasses; introduction of potash fertilizers, which will increase the content of grasses in the herbage and will reduce the specific weight of forbs; application of nitrogen fertilizer in a mixture with potash and complete mineral fertilization, which will reduce the level of forbs by almost half; undersowing of leguminous grasses.

Trophic facilitation in forest restoration: Can Nothofagus trees use ectomycorrhizal fungi of the pioneer shrub Leptospermum?

The benefits of plant‐to‐plant facilitation in ecological restoration are well recognized, yet the potential for indirect trophic facilitation remains understudied. Nothofagus (southern beech; Nothofagaceae) is an iconic southern hemisphere tree genus that is frequently the focus of ecological restoration efforts. One aspect of Nothofagus ecology that may limit restoration success is the availability of appropriate ectomycorrhizal fungi. It has been suggested that pioneer dual‐mycorrhizal hosts such as Leptospermum species (Myrtaceae) could facilitate Nothofagus establishment by providing fungal inoculum, but the capacity for Nothofagus to use Leptospermum ectomycorrhizal fungi is unknown. To investigate potential indirect facilitation, we conducted a common garden pot trial to determine if Nothofagus cliffortioides (mountain beech) can use symbionts from Leptospermum scoparium (mānuka) ectomycorrhizal communities. Nothofagus and Leptospermum seedlings were grown in monoculture and mixed pairs with reciprocal “home” and “away” soil fungal inoculum. ITS2 metabarcoding of eDNA from hyphal ingrowth bags revealed that Nothofagus and Leptospermum inoculum contained different ectomycorrhizal fungal communities, but that half of the common ectomycorrhizal taxa identified were found in both soil types, suggesting generalist fungi exist. Nothofagus was able to form associations with some fungal species originating from Leptospermum inoculum, however, probable spore contamination meant that the proportion of root colonization associated with those species was ambiguous. Root ectomycorrhizal colonization rates were positively associated with seedling biomass, and there was some evidence of a home soil inoculum advantage in Nothofagus, but these effects were minor. Additionally, we found evidence that home inoculum provides a protective advantage against drought stress for Leptospermum seedlings. Our results indicate the potential for using Leptospermum to promote Nothofagus establishment in restoration plantings and highlight the possible benefits of considering fungal mutualists in ecological restoration projects.
