Special Issue Information

Dear Colleagues,

In terrestrial ecosystems, forests cover an estimated 4.1 billion hectares and store up to 56% of both above- and below-ground terrestrial carbon; thus, they have come to play an important role in maintaining ecosystem structure and driving ecosystem function. The circulation of soil mineral nutrients, which is primarily driven by soil microorganisms, supports the growth, regeneration and productivity of forests. In recent years, the scientific community has learned about the turnover of key mineral nutrients between plants and soil and its microbe-driven mechanisms. However, there are still some gaps in our understanding of how soil nutrients and microbial communities affect processes and functions in global forest ecosystems. For example, the roles of stoichiometric properties, the biotic link between above-ground plants and below-ground microbes, and the interactions between macro- and micro-nutrients in growth and carbon sequestration call for more study, especially against a background of global climate and human disturbance. We encourage researchers to submit studies on soil nutrient cycling and related microbial mechanisms in forest ecosystems, including case studies, meta-analysis studies, and model studies, to this Special Issue to promote knowledge and management strategies of forest ecosystems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

Phyllostachys edulis (P. edulis) expansion threatens the structure and function of subtropical forests. Yet, how it impacts soil microbial diversity and network topology has not been fully explored. Herein, a typical transect of P. edulis expansion into Machilus thunbergii (M. thunbergii) forests was selected. Soil samples (0–10 cm) were collected along the transect from three typical vegetation types: P. edulis forest (BF), mixed P. edulis and M. thunbergii forest (BBLF), and M. thunbergii forest (BLF). Subsequently, soil physicochemical properties and microbial diversity were analyzed to elucidate the mechanisms by which P. edulis encroachment affects soil microbial diversity and its network topological characteristics. Results showed that P. edulis expansion increased soil pH and total phosphorus (TP), yet decreased soil water content (SWC), total carbon (TC), and total nitrogen (TN). Additionally, P. edulis expansion enhanced the Shannon and Simpson diversity indices of soil bacteria, while fungal diversity showed a V-shaped pattern, with the lowest in BBLF. Moreover, microbial community composition shifted significantly, with the relative abundances of Proteobacteria, Actinobacteria, Chloroflexi, Basidiomycota, and Mortierellomycota increasing, whereas those of Acidobacteria, Firmicutes, Verrucomicrobia, and Ascomycota were decreasing. Network analysis revealed that P. edulis expansion shifted bacterial networks from cooperative-dominated interactions to a balance of competition and cooperation, while fungal networks formed core-taxa-dominated structures. Overall, our findings clarify that P. edulis expansion reshapes soil nutrient conditions to regulate microbial diversity, composition, and interaction networks, providing critical insights into the belowground ecological effects of P. edulis invasion into subtropical forests.
