Relationships between biodiversity and multiple ecosystem functions (that is, multifunctionality) are context-dependent. Both plant soil microbial diversity have been reported to regulate multifunctionality, but how their relative importance varies along environmental gradients remains poorly understood. Here, we relate multifunctionality across 130 dryland sites a 4,000 km aridity gradient in northern China. Our results show strong positive association species richness less arid regions, whereas diversity, particular of fungi, is positively associated with more regions. This shift the relationships or occur at an level ∼0.8, boundary semiarid climates, which predicted advance geographically ∼28% by end current century. study highlights that loss plants microorganisms may especially consequences under low high conditions, respectively, calls for climate-specific conservation strategies mitigate effects aridification.

It is elemental: soil nutrient stoichiometry drives bacterial diversity

Environmental Microbiology, Год журнала: 2016, Номер 19(3), С. 1176 - 1188

It is well established that resource quantity and elemental stoichiometry play major roles in shaping below aboveground plant biodiversity, but their importance for microbial diversity soil remains unclear. Here, we used statistical modeling on a regional database covering 179 locations six ecosystem types across Scotland to evaluate the of total carbon (C), nitrogen (N) phosphorus (P) availabilities ratios, together with land use, climate biotic abiotic factors, determining scale patterns bacterial diversity. We found composition were primarily driven by variation (total C:N:P ratios), itself linked different uses, secondarily other important biodiversity drivers such as climate, spatial heterogeneity, pH, root influence (plant-soil microbe interactions) biomass (soil microbe-microbe interactions). In aggregate, these findings provide evidence nutrient strong predictor at scale.

Plant–microbiome interactions under a changing world: responses, consequences and perspectives

New Phytologist, Год журнала: 2022, Номер 234(6), С. 1951 - 1959

Summary Climate change is increasing global temperatures and the frequency severity of droughts in many regions. These anthropogenic stresses pose a significant threat to plant performance crop production. The plant‐associated microbiome modulates impacts biotic abiotic on fitness. However, climate change‐induced alteration composition activities microbiomes can affect host functions. Here, we highlight recent advancements our understanding impact (warming drought) plant–microbiome interactions their ecological functions from genome ecosystem scales. We identify knowledge gaps, propose new concepts make recommendations for future research directions. It proposed that short term (years decades), adaptation plants mainly driven by microbiome, whereas long (century millennia), will be equally eco‐evolutionary between its host. A better response ways which mitigate negative inform predictions primary productivity aid developing management policy tools improve resilience systems.

Drought consistently alters the composition of soil fungal and bacterial communities in grasslands from two continents

Global Change Biology, Год журнала: 2018, Номер 24(7), С. 2818 - 2827

The effects of short-term drought on soil microbial communities remain largely unexplored, particularly at large scales and under field conditions. We used seven experimental sites from two continents (North America Australia) to evaluate the impacts imposed extreme abundance, community composition, richness, function bacterial fungal communities. encompassed different grassland ecosystems spanning a wide range climatic properties. Drought significantly altered composition bacteria and, lesser extent, fungi in grasslands continents. magnitude change was directly proportional precipitation gradient. This greater sensitivity more mesic contrasts with generally observed pattern plant arid grasslands, suggesting that may respond differently along gradients. Actinobateria, Chloroflexi, phyla typically dominant dry environments, increased their relative abundance response drought, whereas Glomeromycetes, class regarded as widely symbiotic, decreased abundance. Chlamydiae Tenericutes, mostly pathogenic species, gradient, respectively. Soil enzyme activity consistently attributed drought-induced changes structure rather than diversity. Our results provide evidence has widespread effect assembly communities, one major drivers terrestrial ecosystems. Such responses have important implications for provision key ecosystem services, including nutrient cycling, result weakening plant-microbial interactions incidence certain soil-borne diseases.
