Abstract Below‐ground resource partitioning is among the most prominent hypotheses for driving positive biodiversity–ecosystem function relationship. However, experimental tests of this hypothesis in biodiversity experiments are scarce, and available evidence not consistent.

Abstract The importance of microbial communities (MCs) cannot be overstated. MCs underpin the biogeochemical cycles earth’s soil, oceans and atmosphere, perform ecosystem functions that impact plants, animals humans. Yet our ability to predict manage function these highly complex, dynamically changing is limited. Building predictive models link MC composition a key emerging challenge in ecology. Here, we argue addressing this requires close coordination experimental data collection method development with mathematical model building. We discuss specific examples where model–experiment integration has already resulted important insights into structure. also highlight research questions still demand better experiments models. such needed achieve significant progress understanding dynamics function, make practical suggestions as how could achieved.

Microorganisms drive several processes needed for robust plant growth and health. Harnessing microbial functions is thus key to productive sustainable food production. Molecular methods have led a greater understanding of the soil microbiome composition. However, translating species or gene composition into functionality remains challenge. Community ecology concepts such as biodiversity–ecosystem functioning framework may help predict assembly function plant-associated microbiomes. Higher diversity can increase number resilience plant-beneficial that be coexpressed unlock expression traits are hard obtain from any in isolation. We combine well-established community with molecular microbiology workable enable us enhance promote global change context.

Many microbial communities live in highly competitive surroundings, which the fight for resources determines their survival and genetic persistence. Humans a close relationship with communities, includes health- disease-determining interactions our microbiome. Accordingly, understanding of activities are essential at physiological pathophysiological levels. Here we provide brief overview on competition discuss some its roles consequences that directly affect humans.

Microorganisms are the primary engines of biogeochemical processes and foundational to provisioning ecosystem services human society. Free-living microbial communities (microbiomes) their functioning now known be highly sensitive environmental change. Given microorganisms' capacity for rapid evolution, evolutionary could play a role in this response. Currently, however, few models explicitly consider how evolution will affect responses Here, we propose conceptual framework integrating into microbiome-functioning relationships. We microbiomes respond simultaneously change via four interrelated that overall microbiome (physiological acclimation, demography, dispersal evolution). Recent evidence both laboratory field suggests ecological dynamics occur within microbiomes; implications biogeochemistry under depend on timescales over which these contribute microbiome's Over long term, may an increasingly important microbially driven change, particularly conditions without recent historical precedent.

The bacterial community from estuarine sediment undertakes the bioremediation and energy transformation of anthropogenic pollutants especially polycyclic aromatic hydrocarbons (PAHs). However, information studies on synergism related metabolic profiles under stress PAHs are limited. In this study, sediments were collected co-incubated with a classical PAH, pyrene. results showed that Alpha- Gammaproteobacteria became abundant at late domesticating phase dominant genus ZD0117, uncultivated bacteria affiliated into Gammaproteobacteria. Functional gene analysis based metagenomic sequencing quantitatively changes genes directly to degradation hydrocarbon coordinated involved various pathways such as acylglycerol degradation, nitrogen fixation, sulfate transport system, Arnon-Buchanan cycle, Calvin cycle (P < 0.01 |ρ| > 0.8).

Microbial interaction is an integral component of microbial ecology studies, yet the role, extent, and relevance in community functioning remains unclear, particularly context global biogeochemical cycles. While many studies have shed light on physico-chemical cues affecting specific processes, (micro)biotic controls interactions potentially steering communities leading to altered are less known. Yet, recent accumulating evidence suggests that concerted actions a can be significantly different from combined effects individual microorganisms, giving rise emergent properties. Here, we exemplify importance for ecosystem processes by analysis reasonably well-understood guild, namely, aerobic methane-oxidizing bacteria (MOB). We reviewed literature which provided compelling modulating methane oxidation.

Putative positive between active MOB other microbes were assessed correlation network-based with datasets covering diverse environments where closely interacting members consortium alter oxidation activity.
