Special Issue Information

Dear Colleagues,

Due to global climate change and human activities, ecosystems have degraded or are undergoing degradation. The degradation of ecosystems leads to the extinction of species and a decline in biodiversity across various ecosystems.  Consequently, research on the structure, function and ecological degradation of ecosystems has attracted widespread attention. Soil microorganisms, one of the most critical components of ecosystems, regulate biogeochemical cycles and vegetation succession processes. Their composition and diversity are sensitive biological indicators of ecosystem degradation. Ecosystem degradation causes drastic changes in vegetation composition and growth, as well as the physical and chemical properties of soil and soil aggregates. The composition and function of soil microorganisms are jointly determined by the aboveground vegetation and underground soil nutrient characteristics. Therefore, understanding the synergistic changes in the aboveground plants and soil microorganisms under the influence of global climate change and human activities is of significant importance.

This research theme aims to provide a forum for researchers to share the latest discoveries on the mechanisms of compositional and functional changes in aboveground plants and underground soil microorganisms during the degradation of terrestrial ecosystems such as forests (economic forest). High-quality original research and review articles in this field are encouraged.

Areas of research interest include, but are not limited to:

  1. Changes in the composition and diversity of soil microorganisms in ecosystems with varying vegetation compositions undergoing degradation;
  2. Alterations in the function and structure of soil microorganisms during the invasion of plants in degraded ecosystems;
  3. Variations in soil microbial composition and diversity following ecosystem vegetation succession and their impacts on biogeochemical cycles;
  4. The effects of changes in forest types on the structure and function of soil microorganisms;
  5. The impacts of global climate change and human activities on the changes in forests (economic forest) and soil microorganisms.

Arbuscular mycorrhizal (AM) fungi are one of the most widely distributed microorganisms in all terrestrial ecosystems, playing an important role in supplying nitrogen (N) and phosphorus (P) to plants and in nutrient cycling. The contribution discusses the responses of rises in temperature and atmospheric N deposition to stoichiometric features of plant–soil–litter–microorganism–soil hydrolases in forest ecosystems. It summarizes the role that AM fungi play in the context of global change in carbon (C), N, and P stoichiometric characteristics of forest plant–soil systems. In this study, under conditions of warming with N application, it said the AM fungi will strongly influence the stoichiometric characteristics of C, N, and P in forest ecosystems. In addition to that, the presence of AM fungi may weaken certain impacts of global change on nutrient limitations in plants, increasing their plant dependency on mycorrhizal symbionts. AM fungi also seem to control soil nutrient transformation but simultaneously enhance soil nutrient stability, accelerate litter decomposition, and shorten the cycling time of litter C, N, and P.

Plant leaves harbor a rich diversity of bacteria and fungi that, through their interactions with host plants, assume an influential role in plant physiological and metabolic processes. The unique phyllosphere environment of different plant species may shape and select distinct phyllosphere microbial communities. While most academic research has focused on the phyllosphere microorganisms within the same plant variety, there is relatively limited research on the phyllosphere microbial communities between different varieties. Populus L. is a typical tree species in temperate monsoon climates, widely distributed in northern China, and it constitutes a crucial component of China’s forestry resources. For the purpose of this study, we investigated the community structure and diversity of phyllosphere fungi and bacteria in different poplar varieties under identical growth conditions to elucidate the main factors contributing to differences in phyllosphere microbial communities among these varieties. Our findings revealed variations in nitrogen, phosphorus, starch, and soluble sugar contents among the three poplar species studied. Additionally, there were considerable disparities in both abundance and α diversity index of phyllosphere fungal and bacterial communities among these species. At the phylum level, Ascomycota and Basidiomycota have been identified as the dominant fungal communities; while Proteobacteria and Actinomycetes were dominant bacterial communities. The correlation analysis pointed out that chemical traits in the leaves, in particular the total phosphorus and the quantity of soluble sugar, had a significant correlation with the structure and diversity of the microbial community residing in the phyllosphere. Overall, our results demonstrate that even under identical site conditions, each poplar species harbors its own unique phyllosphere microbial community composition as well as distinct leaf characteristics—highlighting host plant diversity as a crucial factor driving differences in phyllosphere microbial composition.
