Biochar-based fertilizer amendment can improve soil properties partly due to stimulated microbial activities and growths. The karst ecosystem is prone degradation accounts for a large proportion of southwest China. Understanding the response community structure biochar-based application great significance in restoration. A field experiment located China was conducted typical soil, high-throughput sequencing approach used investigate effect on soil. Field trials were set up 24 months using following treatments: control (CK), compost plus NPK (MF), biochar (B), less (half quantity B) (B1MF), (BMF), more (double (B4MF). results elucidated that BMF B4MF treatments had higher contents carbon nutrients N, P, K than other treatments. Soil abundance diversity significantly increased by amendments (BMF B4MF), compared CK (P < 0.05). relative dominant microorganisms, difference composition indicator microbes between each treated group indicated altered structure. There strong correlation (soil C-, N-, P-fractions) Furthermore, network analysis revealed addition scale complexity co-occurrence network. To summarize, enabled keystone species participate resource management nutrient cycling, indicating beneficial restoration karst-degraded soils.

Archaeal and bacterial communities assembly and co-occurrence networks in subtropical mangrove sediments under Spartina alterniflora invasion

Environmental Microbiome, Journal Year: 2021, Volume and Issue: 16(1)

Published: May 3, 2021

Abstract Background Mangrove ecosystems are vulnerable due to the exotic Spartina alterniflora ( S. ) invasion in China. However, little is known about mangrove sediment microbial community assembly processes and interactions under invasion. Here, we investigated co-occurrence networks of archaeal bacterial communities along coastlines Fujian province, southeast Results Assembly overall was driven predominantly by stochastic processes, relative role stochasticity stronger for bacteria than archaea. Co-occurrence network analyses showed that structure more complex The keystone taxa often had low abundances (conditionally rare taxa), suggesting abundance may significantly contribute stability. Moreover, increased drift process (part processes), improved complexity stability, but decreased stability bacteria. This could be attributed influenced diversity dispersal ability, as well soil environmental conditions. Conclusions study fills a gap patterns both archaea ecosystem Thereby provides new insights plant on biogeographic distribution patterns.

Alterations in soil pH emerge as a key driver of the impact of global change on soil microbial nitrogen cycling: Evidence from a global meta‐analysis

Global Ecology and Biogeography, Journal Year: 2022, Volume and Issue: 32(1), P. 145 - 165

Abstract Aim Soil nitrogen (N) cycling is critical to the productivity of terrestrial ecosystems. However, impact global change factors (GCFs) on microbial mediators N pathways has yet be synthesized, and it also remains unclear whether response abundance N‐cycling genes can predict changes in their corresponding processes. Location Global. Time period 2000–2021. Major taxa studied Archaea, bacteria. Methods We synthesized 8322 paired observations soil microorganisms related from field experiments which GCFs (climate nutrient addition) were manipulated. Results found that microbes most resistant elevated CO 2 , experimental warming water addition/reduction; however, addition combination with other significantly increased ammonia oxidizer bacteria ( amoA‐AOB ). The results indicated steady‐state (natural) conditions, main driving bacteria, archaea varied terms contributions climatic edaphic factors. upon manipulation GCFs, induced pH was essential factor associated genes. Notably, ammonia‐oxidizing amoA‐AOA ) genes, involved denitrification nirS nirK ), correlated rates processes, but GCF‐induced shifts potential nitrification rate (PNR) explained well by gene under GCFs. Main conclusions Our study highlights how ongoing might have a profound cycling. field‐based provide new insights into drivers
