Summary: The addition of nitrogen (N) and phosphorus (P) to alpine meadow ecosystems on the Qinghai-Tibetan Plateau has negative effects on soil bacterial community richness and diversity. N addition directly affects soil NH4+-N and decreases plant diversity. Both N and P additions decrease soil bacterial community diversity, which is independent of plant diversity. The composition of soil bacterial community is influenced by nutrient additions and correlated with soil properties.

Summary: Soils in alpine areas of the Tibetan Plateau harbor diverse microbial and macroinvertebrate communities, which play key roles in ecosystem functioning. In this study, we examined the effects of disturbance by plateau zokor rodents on the functional diversity of soil microbial and macroinvertebrate communities. We found that zokor disturbance led to decreased plant biomass and soil organic carbon, but increased the functional diversity of soil microbes and macroinvertebrates. The environmental factors that most influenced functional diversity were soil moisture, temperature, compaction, plant species richness, and belowground biomass of forb. Our findings suggest that environmental changes have a stronger influence on microbial functional diversity compared to macroinvertebrates.

Summary: It was found that the surface soil organic carbon of alpine meadows gradually decreased with land degradation, and changes in plant communities led to alterations in soil organic carbon quality, affecting the loss of soil carbon. Overall, the study suggests that changes in heterotrophic respiration moderated by soil carbon quality alteration due to plant community shifting could be one mechanism for soil carbon loss before moderate degradation, but not the main pathway for soil organic carbon loss at severe and very severe degradation levels.

Summary: Glacial melting can cause alpine gravelization, which in turn leads to degradation of downstream vegetation. This study examines the effects of gravel cover on alpine meadow ecosystem, focusing on community characteristics, soil moisture, and temperature. Results show that gravel cover decreases soil/gravel ratio, topsoil moisture, and various ecological parameters such as above-ground biomass, species richness, community density, and species composition. These findings provide new insights into the impact of alpine gravelization on soil water environment and alpine meadow degradation.

Summary: In alpine systems, cushion plants play a crucial role in modifying local environmental conditions. Different phenotypes of alpine cushion species have varying effects on understory plant species, either promoting or inhibiting their growth. Moreover, dependent species within each community type exhibit divergent responses to different cushion phenotypes, which can be categorized into specific response groups. However, only a limited number of studies have investigated the responses of dependent communities at the species-group level, particularly for both above-ground and below-ground communities.

Summary: The study demonstrated that drought in the late growing season weakens the ecosystem carbon sink in semi-arid grasslands, while a decrease in precipitation during the early growing season did not significantly reduce the overall rate of ecosystem carbon exchange. Therefore, management practices to increase water availability during the late growing season should be prioritized for enhancing carbon sequestration.

Summary: Global nitrogen deposition has had significant impacts on the production and morphology of fine roots in forests, affecting the distribution of carbon. The study found that the N treatment approach and sampling time significantly influenced fine root biomass and morphology. Canopy N addition increased fine root biomass, while understory N addition may decrease it, with fine root biomass being most affected by NH4-N and NO3-N in July. Different N treatment approaches led to varying results, with the effects of understory N addition on fine root biomass potentially being overestimated compared to canopy N addition.

Summary: Aboveground, large and higher trophic-level organisms often respond more strongly to environmental changes than small and lower trophic-level organisms. However, whether this trophic or size-dependent sensitivity also applies to the most abundant animals, microscopic soil-borne nematodes, remains largely unknown. Here, we sampled an altitudinal transect across the Tibetan Plateau and applied a community-weighted mean (CWM) approach to test how differences in climatic and edaphic properties affect nematode CWM biomass at the level of community, trophic group and taxon mean biomass within trophic groups. We found that climatic and edaphic properties, particularly soil water-related properties, positively affected nematode CWM biomass, with no overall impact of altitude on nematode CWM biomass. Higher trophic-level omnivorous and predatory nematodes responded more strongly to climatic and edaphic properties, particularly to temperature, soil pH, and soil water content than lower trophic-level bacterivorous and fungivorous nematodes. However, these differences were likely not (only) driven by size, as we did not observe significant interactions between climatic and edaphic properties and mean biomasses within trophic groups. Together, our research implies a stronger, size-independent trophic sensitivity of higher trophic-level nematodes compared with lower trophic-level ones. Therefore, our findings provide new insights into the mechanisms underlying nematode body size structure in alpine grasslands and highlight that traits independent of size need to be found to explain increased sensitivity of higher trophic-level nematodes to climatic and edaphic properties, which might affect soil functioning.

Summary: The study shows that plant resource inputs have significant impacts on nematode energy flux and community composition in forests at different latitudes. Specifically, litter reduction decreased energy flux of bacterial-feeding nematodes, while root removal reduced energy flux of plant-feeding nematodes. These findings suggest that plant-soil interactions are influenced by climate and plant resource type.
