Abstract Global changes such as seawater intrusion and freshwater resource salinization increase environmental stress imposed on the aquatic microbiome. A strong predictive understanding of responses microbiome to will help in coping with “gray rhino” events environment, thereby contributing an ecologically sustainable future. Considering that microbial ecological networks are tied stability ecosystem functioning abundant rare biospheres different biogeographic patterns important drivers functioning, roles maintaining need be clarified. Here we showed that, increasing salinity induced by freshwater‐to‐seawater transition, diversity reduced significantly taxonomic structure experienced a succession. The complexity were diminished stress. composition microorganisms supporting underwent sharp turnovers during biosphere behaving more robustly than biosphere. Notably, played much role stabilizing under low‐stress environments, but difference between their relative importance narrowed stress, suggesting weakened “Matthew effect” world. With in‐depth insights into ecology our findings highlight adjusting conservation strategies for maintain functions services response rising

ABSTRACT Unraveling how agricultural management practices affect soil biota network complexity and stability these changes relate to processes functions is critical for the development of sustainable agriculture. However, our understanding knowledge still remains unclear. Here, we explored effects intensity on complexity, stability, multifunctionality, as well relationships among factors. Four typical land use types representing a gradient disturbance were selected in calcareous red soils southwest China. The four with increasing included pasture, sugarcane farmland, rice paddy fields, maize cropland. cohesion, topological features (e.g., average degree, clustering coefficient, path length, diameter, graph density, modularity), variation degree used evaluate strength interactions between species, respectively. results showed that intensive increased species competition but decreased stability.

Distinct mechanisms shape soil bacterial and fungal co-occurrence networks in a mountain ecosystem

FEMS Microbiology Ecology, Journal Year: 2020, Volume and Issue: 96(4)

Published: Feb. 27, 2020

ABSTRACT Understanding microbial network assembly is a promising way to predict potential impacts of environmental changes on ecosystem functions. Yet, soil in mountain ecosystems and its underlying mechanisms remain elusive. Here, we characterized co-occurrence networks across 12 altitudinal sites Mountain Gongga. Despite differences habitats, bacterial separated into two different clusters by altitude, namely the lower higher altitudes, while fungi did not show such pattern. Bacterial encompassed more complex closer relationships at had which could be attributed niche differentiation caused high variations environments plant communities. Both abiotic biotic factors (e.g. pH community composition) shaped networks. However, played important roles than measured for fungal assembly. Further analyses suggest that multiple including overlap/differentiation, cross-feeding competition between microorganisms play shaping This study reveals response ecological factors, provides insights our comprehensive understanding their functional potentials ecosystems.

Leaf and Root Endospheres Harbor Lower Fungal Diversity and Less Complex Fungal Co-occurrence Patterns Than Rhizosphere

Frontiers in Microbiology, Journal Year: 2019, Volume and Issue: 10

Published: May 8, 2019

Plant-associated microbiomes are key determinants of host-plant fitness, productivity, and function. However, compared to bacterial community, we still lack fundamental knowledge concerning the variation in fungal microbiome at plant niche level. In this study, quantified communities rhizosphere soil, as well leaf root endosphere compartments a subtropical island shrub, Mussaenda kwangtungensis, using high-throughput DNA sequencing. We found that varied significantly across different compartments. Rhizosphere soil exhibited highest level diversity, whereas lowest was endosphere. Further, inhabiting shared greater proportion operational taxonomic units (OTUs) with than endophyte communities, despite significant separation community structure between two belowground The co-occurrence networks three M. kwangtungensis showed scale-free features non-random patterns matched topological properties small-world evidently modular structure. Additionally, network more complex higher centrality connectedness networks. Overall, our findings provide comprehensive insights into structural variability, differentiation, associated microbiome.
