Special Issue Information

Dear Colleagues,

Forest ecosystem degradation resulting from climatic variations and irrational human activities is currently one of the most important environmental problems hindering the improvement of the environment and socio-economic status of developing countries and regions. The major outcomes of land degradation in forest ecosystems are soil erosion, soil organic carbon depletion, soil nutrient loss, and biodiversity loss. In addition to the on-site adverse effects, forest degradation also has off-site adverse impacts on soil, water, and air resources. In the context of sustainable management and resource use in forests, many kinds of restoration practices have been utilized worldwide that are expected to succeed. This Special Issue plans to give an overview of the most recent advances in the field of soil formation and carbon accumulation during forest ecosystem restoration. The aim of this Special Issue is to collect high-quality research addressing research from different regions concerning soil formation, carbon accumulation, and soil quality improvement during forest ecosystem restoration.

Potential topics include, but are not limited to:

  • Monitoring of forest degradation, restoration, and rehabilitation;
  • Monitoring C stocks and their fractions in forest ecosystems;
  • Changes in carbon stability during forest restoration;
  • Processes and mechanisms of forest carbon sequestration during restoration;
  • Changes in soil physical, chemical, and biological properties;
  • Assessing soil quality in different forest ecosystems;
  • Sustainable management and resource use of forests in specific regions.

The stoichiometric characteristics of plant nitrogen (N) and phosphorus (P) and their correlations with soil properties are regarded as key for exploring plant physiological and ecological processes and predicting ecosystem functions. However, quantitative studies on the relative contributions of water–salt gradients and nutrient gradients to plant stoichiometry are limited. In addition, previous studies have been conducted at the plant species and individual levels, meaning that how community-scale stoichiometry responds to soil properties is still unclear. Therefore, we selected typical sample strips from 13 sampling sites in arid regions to assess the leaf N and P levels of 23 species of desert plants and measure the corresponding soil water content, total salt content, total nitrogen content, and total phosphorus content. The aim was to elucidate the main soil properties that influence the stoichiometric characteristics of desert plants and compare the individual and community responses to those soil properties. Our results indicated that the growth of desert plants is mainly limited by nitrogen, with individual plant leaf nitrogen and phosphorus concentrations ranging from 4.08 to 31.39 mg g−1 and 0.48 to 3.78 mg g−1, respectively. Community stoichiometry was significantly lower than that of individual plants. A significant correlation was observed between the mean N concentration, P concentration, and N:P ratio of plant leaves. At the individual plant scale, aridity significantly reduced leaf N and P concentrations, while high salt content significantly increased leaf N concentrations. At the community scale, aridity had no significant effects on leaf nitrogen or phosphorus stoichiometry, while high salinity significantly increased the leaf N:P ratio and there were no significant interactions between the aridity and salinity conditions. No significant effects of soil nutrient gradients were observed on plant N and P stoichiometric characteristics at the individual or community levels. These results suggest that individual desert plants have lower leaf N and P concentrations to adapt to extreme drought and only adapt to salt stress through higher leaf N concentrations. The N and P stoichiometric characteristics of desert plant communities are not sensitive to variations in aridity and salinity in this extreme habitat. The results of this study could enhance our perceptions of plant adaptation mechanisms to extreme habitats within terrestrial ecosystems. Full article
