“…Consistent with these findings, no differences in microbial community composition were found according to temperature treatments in these samples over the first five years of whole ecosystem warming, although warming exponentially increased CH4 emissions and enhanced CH4 production rates throughout the entire soil profile [65]. These results are also consistent with prior studies that have shown that soil microbial community responses to similar temperature increases can take multiple years to manifest [79][80][81]. For example, significant differences in soil microbial community composition were found in Harvard Forest after 20 years of soil warming at 5 °C above ambient temperatures [79], after seven years in Austrian forest soils warmed 4 °C above ambient temperatures [80], and after five years of warming the soil only 1.5 °C above ambient temperatures in a Castanopsis hystrix plantation (planted forest) [81].…”

Warming has been shown to substantially alter the community composition, diversity, and N2 fixation activity of peat moss microbiomes [66], and in microcosms of surface peat collected from the SPRUCE site, microbial diversity was negatively correlated with temperature, suggesting that prolonged exposure of the peatland ecosystem to elevated temperatures will lead to a loss in microbial diversity [82].…”

Background: Peatlands are expected to experience sustained yet fluctuating higher temperatures due to climate change, leading to increased microbial activity and greenhouse gas emissions. Despite mounting evidence for viral contributions to these processes in peatlands underlain with permafrost, little is known about viruses in other peatlands. More generally, soil viral biogeography and its potential drivers are poorly understood at both local and global scales. Here, 87 metagenomes and five viral size-fraction metagenomes (viromes) from a boreal peatland in northern Minnesota (the SPRUCE whole-ecosystem warming experiment and surrounding bog) were analyzed for dsDNA viral community ecological patterns, and the recovered viral populations (vOTUs) were compared to our curated PIGEON database of 266,805 vOTUs from diverse ecosystems. Results: Within the SPRUCE experiment, viral community composition was significantly correlated with peat depth, water content, and carbon chemistry, including CH4 and CO2 concentrations, but not with temperature during the first two years of warming treatments. Peat vOTUs with aquatic-like signatures (shared predicted protein content with marine and/or freshwater vOTUs) were significantly enriched in more waterlogged surface peat depths. Predicted host ranges for SPRUCE vOTUs were relatively narrow, generally within a single bacterial genus. Of the 4,326 SPRUCE vOTUs, 164 were previously detected in other soils, mostly peatlands. None of the previously identified 202,372 marine and freshwater vOTUs in our PIGEON database were detected in SPRUCE peat, but 1.9% of 78,203 genus-level viral clusters (VCs) were shared between soil and aquatic environments. On a per-sample basis, vOTU recovery was 32 times higher from viromes compared to total metagenomes. Conclusions: Results suggest strong viral "species" boundaries between terrestrial and aquatic ecosystems and to some extent between peat and other soils, with differences less pronounced at the "genus" level. The significant enrichment of aquatic-like vOTUs in more waterlogged peat suggests that viruses may also exhibit niche partitioning on more local scales. These patterns are presumably driven in part by host ecology, consistent with the predicted narrow host ranges. Although more samples and increased sequencing depth improved vOTU recovery from total metagenomes, the substantially higher per-sample vOTU recovery after viral particle enrichment highlights the utility of soil viromics.

“…Warming treatment can effectively increase soil temperatures (Wang et al, 2019; Li et al, 2018) and thereby decrease soil water levels (Wang et al, 2014; Chen et al, 2018). In our experiment, warming treatment resulted in higher soil temperatures than those observed in the control treatment (Figs.…”

“…Therefore, warming effects on R S and Q 10 are affected by the above factors. Warming treatment can change substrate supplies and microbial activities or communities (Wang et al, 2019; Li et al, 2018). Therefore, soil aggregate protection and microbial communities can also affect the Q 10 values (Qin et al, 2019).…”

Background Soil respiration (RS) plays an important role in the concentration of atmospheric CO2 and thus in global climate patterns. Due to the feedback between RS and climate, it is important to investigate RS responses to climate warming. Methods A soil warming experiment was conducted to explore RS responses and temperature sensitivity (Q10) to climate warming in subtropical forests in Southwestern China, and infrared radiators were used to simulate climate warming. Results Warming treatment increased the soil temperature and RS value by 1.4 °C and 7.3%, respectively, and decreased the soil water level by 4.2% (%/%). Both one- and two-factor regressions showed that warming increased the Q10 values by 89.1% and 67.4%, respectively. The effects of water on Q10show a parabolic relationship to the soil water sensitivity coefficient. Both RS and Q10 show no acclimation to climate warming, suggesting that global warming will accelerate soil carbon release.

Understanding the dynamic relationships between soil organic carbon (SOC) and stand age are essential to quantify and predict the terrestrial carbon sequestration potential. However, the spatial patterns in the response of rubber plantation SOC to stand age and their driving factors remain unclear. Based on SOC and its components measurement at different soil depths (0–40 cm) in rubber plantations under five different age classes (0–5, 5–10, 10–20, 20–30, and >30 years) in three major rubber cultivation regions in China, distribution pattern and controlling factors of SOC were investigated. We found that SOC and its components showed significant spatial variability vertically with soil depth and laterally across sampling sites. SOC contents in three major rubber cultivation regions range from 4.48 to 20.13 g kg−1 at a depth of 0–40 cm. Among the sampling sites, Jinghong had the highest SOC content at a depth of 0–10 cm (20.13 g kg−1). On a large‐scale, the relationship between SOC and stand age in rubber plantations did not show a consistent pattern among different sampling sites. Additionally, annual rainfall, soil moisture content, and soil pH had a stronger impact on SOC in rubber plantations compared to stand age. The results indicated that the spatial variability of SOC in rubber plantations with stand age could be influenced by specific soil properties and climate‐related variables at each sampling site. This study emphasized the significance of conducting multi‐site, multi‐scale studies to enhance our understanding of SOC dynamics and its influencing factors, and help to more accurately predict the dynamic changes of soil carbon storage in rubber plantations.
