Seasonal variations of environmental factors generally result in considerable changes microbiomes, yet we still lack a clear understanding how microbial communities maintain their ecological stability. Here, analyze long-term (nine years) high-throughput sequencing dataset by network analysis to illustrate the stability varies among seasons lake ecosystems. The results showed that networks were distinctly different seasons, and most complex autumn exhibited highest We found strong connecting structures microbes (large modules) significantly (P < 0.05) correlated with water temperature pH, which would negatively affect keystone taxa destabilize communities. more stable removal unstable networks. Moreover, specific due filtering relevant interspecific interactions. These suggested seasonal could influence community via regulation taxa. Thus, be used as indicators reflect findings improve our co-occurrence patterns reveal mechanism aquatic

From diversity to complexity: Microbial networks in soils

Soil Biology and Biochemistry, Год журнала: 2022, Номер 169, С. 108604 - 108604

Network analysis has been used for many years in ecological research to analyze organismal associations, example food webs, plant-plant or plant-animal interactions. Although network is widely applied microbial ecology, only recently it entered the realms of soil shown by a rapid rise studies applying co-occurrence communities. While this application offers great potential deeper insights into structure ecosystems, also brings new challenges related specific characteristics datasets and type questions that can be addressed. In Perspectives Paper we assess ecology due small-scale heterogeneity environment nature datasets. We review different approaches construction are commonly discuss their features limitations. Using test dataset communities from two depths forest soil, demonstrate how experimental designs constructing algorithms affect resulting networks, turn may influence conclusions. will reveal assumptions method, methods preparing dataset, definitions thresholds structure. Finally, particular approached analyzing interpreting properties. Targeting these properties meaningful way allow technique not merely descriptive, but hypothesis-driven research.

Microbial Biostimulants as Response to Modern Agriculture Needs: Composition, Role and Application of These Innovative Products

Plants, Год журнала: 2021, Номер 10(8), С. 1533 - 1533

Опубликована: Июль 27, 2021

An increasing need for a more sustainable agriculturally-productive system is required in order to preserve soil fertility and reduce biodiversity loss. Microbial biostimulants are innovative technologies able ensure agricultural yield with high nutritional values, overcoming the negative effects derived from environmental changes. The aim of this review was provide an overview on research related plant growth promoting microorganisms (PGPMs) used alone, consortium, or combination organic matrices such as (PBs). Moreover, effectiveness role microbial biological tool improve fruit quality limit degradation discussed. Finally, increased use these products requires achievement accurate selection beneficial consortia, ability prepare future agriculture challenges. Hence, implementation microorganism positive list provided by EU (2019/1009), desirable.

Destabilized microbial networks with distinct performances of abundant and rare biospheres in maintaining networks under increasing salinity stress

iMeta, Год журнала: 2023, Номер 2(1)

Опубликована: Янв. 9, 2023

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

Grassland degradation-induced declines in soil fungal complexity reduce fungal community stability and ecosystem multifunctionality

Soil Biology and Biochemistry, Год журнала: 2022, Номер 176, С. 108865 - 108865

Опубликована: Окт. 29, 2022

Soil microorganisms are major regulators of ecosystem functioning and under threat from human-induced disturbances. Among these threats is grassland degradation, which estimated to affect 49% the area worldwide, threatening biodiversity functioning. Yet, we currently lack an understanding how degradation influences belowground microbial communities, their stability, functioning, effective restoration efforts for recovery important properties. Here, assessed soil fungal network complexity a suite functions along well-characterised gradient on Qinghai-Tibetan Plateau, conducted accompanying microcosm experiment designed test effects stability in communities. We found that with increasing levels communities became less complex were compositionally stable when confronted drought laboratory conditions. Moreover, this degradation-induced reduction community was associated lower multifunctionality. However, multifunctionality failed recover even after ten years restoration. Our results indicate simplification can potentially impair multifunctionality, thereby highlighting need protect restore healthy grasslands • Grassland resulted drought. Degradation-induced Fungal

Afforestation can lower microbial diversity and functionality in deep soil layers in a semiarid region

Global Change Biology, Год журнала: 2022, Номер 28(20), С. 6086 - 6101

Опубликована: Июль 9, 2022

Afforestation is an effective approach to rehabilitate degraded ecosystems, but often depletes deep soil moisture. Presently, it not known how afforestation-induced decrease in moisture affects microbial community and functionality, hindering our ability understand the sustainability of rehabilitated ecosystems. To address this issue, we examined impacts 20 years afforestation on bacterial community, co-occurrence pattern, functionalities along vertical profile (0-500 cm depth) a semiarid region China's Loess Plateau. We showed that effects with deep-rooted legume tree cropland were greater than top layers, resulting decreased beta diversity, more responsive taxa functional groups, increased homogeneous selection, network robustness soils (120-500 cm). Organic carbon nitrogen decomposition rates multifunctionality also significantly by afforestation, limitation soils. Moreover, changes functionality layer was largely related Such negative should be fully considered for assessing afforestation's eco-environment ecosystems because have important influence forest arid climates.
