Shrub invasion affects plant growth and soil physicochemical properties, resulting in microbiota metabolic pathway changes. However, little is known about the shrub expansion intensity of microbial processes. In this study, we used metagenome sequencing technology to investigate changes C N pathways community structures, along with different intensities, Sanjiang Plain wetlands. Different intensities significantly affected composition (β diversity), no significant effect on α diversity compared CK. AN, pH, TP were major factors influencing community’s structures. Compared CK, did not affect fixation central metabolism but reduced methanogenesis, which involves CO2-to-methane transition that occurs methane metabolism, denitrification, nitrite nitric oxide (nirK or nirS) metabolism. This study provides an in-depth understanding biogeochemical cycles wetland ecosystems cold northern regions undergoing invasion.

Alpine tundra, covering 3% of the Earth's land surface, harbors approximately 4% higher plant species. Changes in this vegetation significantly impact biodiversity and ecosystem services. Recent studies have primarily focused on large-scale long-term changes polar high-latitude regions. However, study short-term their primary drivers has received insufficient attention alpine tundra. This aimed to investigate dominant tundra Changbai Mountains-located at southern edge distribution Eastern Eurasia-over a short period by re-surveying permanent plots 2019 comparing them with data from 2014.

Understanding the physiological adaptations of non-treeline trees to environmental stress is important understand future shifts in species composition and distribution current treeline ecotone. The aim present study was elucidate mechanisms formation upper elevation limit tree species, Picea jezoensis, carbon allocation strategies on Changbai Mountain. We employed 13C situ pulse labeling technique trace photosynthetically assimilated jezoensis at different elevational positions (tree its (TSAUE, 1700 m a.s.l.) under ecotone; a lower position (TSALE, 1400 a.s.l.). analyzed non-structural carbohydrate (NSC) concentrations various tissues following labeling. Our findings revealed significant shift TSAUE compared TSALE. There pronounced increase δ13C belowground components (roots, soil, soil respiration) Furthermore, C flow rate within plant-soil-atmosphere system faster, residence time plant shorter TSAUE. trends indicate enhanced sink activity TSAUE, with newly being preferentially directed there, suggesting more conservative strategy by P. higher elevations harsher environments. Such strategy, prioritizing storage roots, likely aids withstanding winter cold expense aboveground growth during growing season, leading reduced results shed light adaptive governing limits trees, enhances our understanding how might respond ongoing climate change.

Elevation is one of the most influential factors affecting soil characteristics and microbial communities in forest ecosystems. Nevertheless, there no consensus on how characteristics, microbials, their relationships response to elevation mountain ecosystem. We investigated physicochemical activity enzymes, community at elevational sites from 600 2400 m above sea level (asl) western slopes Fanjing Mountain ecosystem, China. The were determined by high throughput 16S rRNA ITS amplicon sequencing. results demonstrated that total nitrogen (TN) showed a slight decrease, whereas phosphorus (TP) potassium (TK) gradually tended increase with increasing elevation. large macroaggregates (>2 mm) accounted for largest proportion aggregate fraction (66.23%–76.13%) 0–10 cm layer average values electrical conductivity (EC), organic carbon (SOC), cation exchange capacity (CEC) concentration 0–60 undulated elevation, highest observed 1500–1800 asl 1800–2100 asl, respectively. activities urease, sucrase, acid phosphatase, catalase clearly differed (p < 0.05) minimum found 2100–2400 asl.
