The extracellular enzymes secreted by soil microorganisms play a pivotal role in the decomposition of organic matter and global cycles carbon (C), phosphorus (P), nitrogen (N), also serving as indicators health fertility. Current research is extensively analyzing these microbial populations enzyme activities diverse ecosystems climatic regions, such forests, grasslands, tropics, arctic regions deserts. Climate change, warming, intensive agriculture are altering activities. Yet, few reviews have thoroughly explored key required for fertility effects abiotic factors on their functionality. A comprehensive review thus essential to better understand C, P, N cycles, response climate changes, ecosystems, farming, fertilization. Studies indicate that temperature, moisture, water content, pH, substrate availability, average annual temperature precipitation significantly impact Additionally, change has shown ambiguous activities, causing both reductions enhancements catalytic functions.

Soil fungal community and co-occurrence network patterns at different successional stages of black locust coppice stands

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 16

Black locust (Robinia pseudoacacia L.) plantations transition from seedling to multi-generation coppice systems, leading declines in productivity and biodiversity. However, the structural functional reorganization of soil fungal communities during this remains poorly understood. This study aimed characterize community dynamics across successional stages black stands assess their implications for health ecosystem resilience. Soil three (first-generation forest, first- second-generation forests) were analyzed over one year using ITS high-throughput sequencing. We evaluated diversity, guild composition, co-occurrence networks, integrating statistical analyses (PERMANOVA, ANOSIM, FUNGuild) network theory seasonal shifts.

Published: May 14, 2025

ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also case for soils, but no study to date provided an overall synthesis of current state knowledge. Here we fill this gap with a first global analysis published research on cryptogams, microorganisms, and fauna soils above treeline, structured Based corpus almost 1400 publications expertise 37 soil scientists worldwide, summarise what known about distribution patterns each these organismal groups, specifically along elevation, provide overview available knowledge drivers explaining their changes. In particular, document elevation‐dependent decrease faunal while cryptogams there initial increase followed by towards nival belt. Thus, our data confirm key role that elevation plays shaping biodiversity organisms soils. The response prokaryote turn, was more diverse, whereas fungal appeared be substantially influenced plants.

Soil fungi play an integral and essential role in maintaining soil ecosystem functions. The understanding of altitude variations their drivers fungal community composition diversity remains relatively unclear. Mountains provide open, natural platform for studying how the responds to climatic variability at a short distance.

Soil microbial community composition and extracellular enzyme activity are two main drivers of biogeochemical cycling. Knowledge about their elevational patterns is great importance for predicting ecosystem functioning in response to climate change. Nevertheless, there no consensus on how soil vary with elevation, little known variations the eastern Qinghai-Tibetan Plateau, a region sensitive global We therefore investigated using phospholipid fatty acids (PLFAs) analysis, activities at 2,820 m (coniferous broadleaved mixed forest), 3,160 (dark coniferous 3,420 (alpine dwarf 4,280 shrubland) above sea level. Our results showed that changed significantly along gradient. Biomass total microbes, bacteria, arbuscular mycorrhizal fungi highest elevation were lowest among four elevations. In contrast, involved carbon (C)-, nitrogen (N)-, phosphorus (P)- acquiring exhibited maximum values elevation.
