Precipitation change strongly influences soil microbial communities, and precipitation patterns have become a key factor affecting carbon nitrogen cycling processes in wetland ecosystems. The cbbL gene is the fixation of dioxide during Calvin cycle. However, response cbbL-carrier carbon-fixing microorganisms lakeshore to remains unclear. To this end, we established 25% 50% increased decreased treatments, along with natural control, used high-throughput sequencing investigate community...
Global climate change has accelerated the reduction of permafrost regions across different altitude gradients, shortening duration freezing period to varying extents. However, response soil microorganisms frozen soils along gradients remains unclear. In this study, we employed 16S rRNA sequencing and LC-MS metabolomics investigate microbial communities metabolites vertical stratification in Qinghai Lake region. The results indicated that Proteobacteria, Firmicutes, Actinobacteria were key...
Global warming has intensified the changes in wetland carbon cycling processes, and cbbL gene, which plays a key role fixation, is significantly affected by warming. Therefore, we set up open-top chamber natural controls used amplicon sequencing to investigate response of carbon-fixing microbial community alpine lakeshore We found that after treatment, relative abundances Actinobacteria Chlorophyta increased, while abundance Cyanobacteria decreased (p < 0.05). Soil temperature moisture...
Qinghai Lake, the largest inland saline lake in China, plays a vital role wetland carbon cycling. However, structure and function of soil bacterial communities its estuarine nearshore wetlands remain unclear. This study examined effects type depth on diversity, community composition, functional potential Shaliu, Heima, Daotang River using high-throughput sequencing. The results showed that significantly influenced communities. Nearshore exhibited lower diversity 0–10 cm layer, while deeper...
Carbon-sequestering microorganisms play an important role in the carbon cycle of wetland ecosystems. However, response mechanism carbon-sequestering microbial communities to type changes and their relationship with soil remain unclear. To explore these differences identify main influencing factors, this study selected marsh wetlands, river wetlands lakeside around Qinghai Lake as research subjects. High-throughput sequencing was employed analyze functional gene cbbM microorganisms. The...
The nitrogen cycling process in alpine wetlands is profoundly affected by precipitation changes, yet the dynamic response mechanism of denitrifiers to long-term shifts wetland Qinghai-Tibet Plateau remains enigmatic. Utilizing high-throughput sequencing analysis nirS-type functional genes, this study delved into changes Qinghai Lake. findings revealed that Lake were primarily Proteobacteria, and Alpha diversity exhibited a negative correlation with gradient, deterministic processes...
Global climate warming has led to the deepening of active layer permafrost on Tibetan Plateau, further triggering thermal subsidence phenomena, which have profound effects carbon cycle regional ecosystems. This study conducted (W) and (RR) control experiments using an Open-Top Chamber (OTC) device in river source wetlands Qinghai Lake basin. The aim was assess impacts soil temperature, volumetric water content, biomass, microbial diversity, respiration (both autotrophic heterotrophic...
The dramatic changes in precipitation patterns on the Tibetan Plateau affected carbon-sequestering microbial communities within wetland ecosystems, which were closely related to responses and adaptation mechanisms of alpine ecosystems climate change. This study focused soils subjected different gradient treatments employed high-throughput sequencing technology analyze soil cbbM communities. results indicated that Proteobacteria dominant community responsible for carbon sequestration Wayan...
