Summary: Soil microbes and enzymes in permafrost peatland are sensitive to temperature changes, with long-term warming leading to increased microbial abundance, accelerated carbon cycling, and enhanced nitrogen availability. The study results provide new insights into the response of plant-soil-microbe interactions in permafrost peatlands to climate change.

Summary: In this study, the peatland-vegetation model (LPJ-GUESS) was used to simulate peatland carbon dynamics under different future climate conditions. It was found that under less pronounced warming, peatlands may enhance their carbon sink capacity and buffer the effects of climate change. However, in a warmer world, higher respiration rates will dominate the carbon dynamics and reduce the carbon sink capacity.

Summary: This study compares the response rate and degree of carbon and nitrogen in peat soil under permafrost degradation in different sample areas. The results show that soil organic carbon and nitrogen contents are highest in the top 10 cm soil layer and permafrost regions have surface aggregation. The carbon content decreases with depth in different types of frozen soil, and the distribution pattern of total nitrogen content varies among permafrost types. Soil carbon responds faster and accumulates to a higher degree than soil nitrogen in response to permafrost degradation. Understanding the influence of permafrost degradation on peatland soil carbon and nitrogen is crucial for climate change mitigation and permafrost conservation.

Summary: The rhizosphere microenvironment plays a crucial role in plant-soil physiological processes. Differences in microbial communities were observed among different types of rhizosphere and non-rhizosphere soils, and permafrost degradation was found to greatly alter the carbon and nitrogen cycling processes mediated by soil microorganisms.

Summary: Stordalen Mire is a peatland in arctic Sweden that exhibits a habitat gradient from permafrost palsa to thawed fen. The evaluation of carbon accumulation rates across this gradient using three independent approaches showed that recent carbon balance in this area is being offset by rising methane emissions, leading to net CO2-equivalent emissions. This indicates that the mire and similar permafrost ecosystems will exert a warming influence on future climate.

Summary: Long-term cultivation of sugar beet affects both the yield of sugar beet and the composition of rhizosphere soil bacteria. This study analyzed sugar beet growth and rhizosphere soil bacterial diversity in both long-term cultivation fields and initial planting fields. The results showed that sugar beet leaf disease was significantly aggravated and yield was reduced in long-term cultivation fields compared to initial planting fields. The content of available phosphorus in rhizosphere soil and the diversity of the bacterial community were also significantly decreased. Different bacterial species were found in the two types of fields, and certain metabolic functions related to nutrient cycling were decreased. The diversity of rhizosphere soil bacteria was negatively correlated with leaf disease and positively correlated with sugar yield.

Summary: The study found that temperature and sampling sites significantly influenced SOC mineralization in permafrost peatlands, with elevated temperatures increasing the rate of carbon mineralization. The mineralization of soil carbon was positively correlated with the concentrations of soil dissolved organic carbon, NH4+-N, NO3--N, as well as the abundances of bacteria, fungi, methanotrophs and nirK denitrifiers in the soil.

Summary: Soil microbial necromass plays a critical role in soil organic carbon (SOC) sequestration, with elevated CO2 increasing fungal-derived C and warming increasing bacterial-derived C in SOC. The combination of elevated CO2 and warming resulted in the highest total microbial necromass and SOC accumulation, with root biomass indirectly affecting total amino sugar concentration through increased microbial biomass. Further research involving multiple sampling times is needed to understand the temporal dynamics of these properties.

Summary: Northwestern Canada is warming at an alarming rate, causing permafrost thaw and changes in the ecosystem. A study conducted in the Mackenzie River valley found that peat and carbon accumulation rates have increased since the 1980s and 2000s in different permafrost zones. This highlights the importance of considering the recent growth of mosses and carbon uptake to assess carbon emissions following permafrost thaw.

Summary: Short-term warming did not significantly impact the alpha diversity of soil bacterial and fungal communities, but had a significant effect on the vertical structure of fungal community. Niche-based process drove the vertical assembly of bacterial community, while dispersal-based process regulated the vertical structure of fungal community.

Summary: This study assessed the impact of conservation agriculture on the biological soil health index in a rice-wheat system in the Indo-Gangetic Plains. The results showed that zero till direct seeded rice and crop residue incorporation could improve soil organic carbon, enzyme activities, and microbial population. Specifically, the inclusion of mungbean residues and sesbania brown manuring significantly increased the abundance of the nifH gene in the soil.

Summary: Integrating diverse cover crops into dryland crop-fallow rotations can enhance soil nutrient and water retention, suppress soil-borne pests, and improve soil health. The effects on soil nematode communities are modulated by the functional type and mixture composition of the cover crops. Selecting cover crops with appropriate traits can improve soil health through suppression of plant-parasitic nematodes, promotion of free-living nematodes, and enhancement of soil food web complexity.

Summary: In extreme desert environments, black septate endophytes (DSE) can benefit the relict plant Gymnocarpos przewalskii by assisting it to survive and maintain ecosystem stability. The colonization of DSE in the roots of G. przewalskii varies significantly with seasons and sites, with soil properties being a major factor affecting the composition of DSE. Additionally, the functional metabolite composition of DSE strains varies greatly with different drought levels and isolates, indicating the potential complementarity between different strains in helping hosts cope with drought stress.
