Soils underpin terrestrial ecosystem functions, but they face numerous anthropogenic pressures. Despite their crucial ecological role, we know little about how soils react to more than two environmental factors at a time. Here, show experimentally that increasing the number of simultaneous global change (up 10) caused directional changes in soil properties, processes, and microbial communities, though there was greater uncertainty predicting magnitude change. Our study provides blueprint for...
Abstract DNA metabarcoding refers to the DNA‐based identification of multiple species from a single complex and degraded environmental sample. We developed new sampling extraction protocols suitable for analyses targeting soil extracellular DNA. The proposed protocol has been designed reduce, as much possible, influence local heterogeneity by processing large amount resulting mixing many different cores. is based on use saturated phosphate buffer. were validated first analysing plant set 12...
Abstract Biodiversity is crucial for the provision of ecosystem functions. However, ecosystems are now exposed to a rapidly growing number anthropogenic pressures, and it remains unknown whether biodiversity can still promote functions under multifaceted pressures. Here we investigated effects soil microbial diversity on properties when faced with an increasing simultaneous global change factors in experimental microcosms. Higher had positive effect no or few (i.e., 1–4) were applied, but...
Soil structure, the complex arrangement of soil into aggregates and pore spaces, is a key feature soils biota. Among them, filamentous saprobic fungi have well-documented effects on aggregation. However, it unclear what properties, or traits, determine overall positive effect To achieve progress, would be helpful to systematically investigate broad suite fungal species for their trait expression relation these traits Here, we apply trait-based approach set 15 measured under standardized...

Summary Root traits respond to drought in a species‐specific manner, but little is known about how soil fungal communities and root concert. In glasshouse experiment, we determined the response of pathogens, saprotrophs, mutualistic all fungi associated with roots 24 plant species subjected drought. At harvest, were characterized by sequencing. Data on extracted from previously published work. Differences beta diversity between control specific. For some species, saprotrophic increased...
Abstract The stability of plant biomass production in the face environmental change is fundamental for maintaining terrestrial ecosystem functioning, as ultimate source energy nearly all life forms. However, most studies have focused on stabilising effect diversity, neglecting soil biodiversity, largest reservoir biodiversity Earth. Here we investigated effects and temporal under varying simulated precipitation grassland microcosms. Soil loss reduced by suppressing asynchronous responses...
Abstract Trait-based frameworks are promising tools to understand the functional consequences of community shifts in response environmental change. The applicability these soil microbes is limited by a lack trait data and focus on categorical traits. To address this gap for an important group microorganisms, we identify trade-offs underlying fungal economics spectrum based large collection 28 saprobic isolates, derived from common grassland grown culture plates. In dataset, ecologically...
Tree growth limitation at treeline has mainly been studied in terms of carbon while effects and mechanisms potential nitrogen (N) are barely known, especially the southern hemisphere. We investigated how soil abiotic properties microbial community structure composition change from lower to upper sites within three vegetation belts ( Nothofagus betuloides N. pumilio forests, alpine vegetation) across an elevation gradient (from 0 650 m a.s.l.) Cordillera Darwin, Patagonia. Increasing was...
Plants affect the spatial distribution of soil microorganisms, but influence local abiotic context is poorly documented. We investigated effect a single plant species, cushion Silene acaulis, on habitat conditions and microbial community. collected from inside (In) outside (Out) cushions calcareous siliceous cliffs in French Alps along an elevation gradient (2,000-3,000 m.a.s.l.). The composition communities was assessed by Capillary-Electrophoresis Single Strand Conformation Polymorphism...
Global environmental change poses threats to plant and soil biodiversity. Yet, whether biodiversity loss can further influence community's response global is still poorly understood. We created a gradient of using the dilution-to-extinction approach, investigated effects on communities during following manipulations simulating disturbances in experimental grassland microcosms. Grass herb biomass was decreased by drought promoted nitrogen deposition, fast recovery observed disturbances,...
Summary Anthropogenic atmospheric deposition can increase nutrient supply in the most remote ecosystems, potentially affecting soil biodiversity. Arbuscular mycorrhizal fungal (AMF) communities rapidly respond to simulated eutrophication tropical forests. Yet limited spatio‐temporal extent of such manipulations, together with often unrealistically high fertilization rates employed, impedes generalization responses. We sequenced mixed root AMF within a seven year‐long fully factorial nitrogen...

Arbuscular mycorrhizal (AM) fungi provide a range of functions in natural and managed ecosystems. However, the trajectory AM fungal diversity after land degradation is poorly known. We studied succession along an agricultural recultivation chronosequence open-cast mining near Cologne, Germany. used high-throughput sequencing large-subunit ribosomal RNA genes to characterize soil communities 10 fields spanning 52 years recultivation. During three years, soils are recultivated with legume,...
Abstract The fungal mycelium represents the essence of lifestyle, and understanding how a is constructed fundamental importance in biology ecology. Previous studies have examined initial developmental patterns or focused on few strains, often mutants model species, frequently grown under non-harmonized growth conditions; these factors currently collectively hamper systematic insights into rules architecture. To address this, we here use broader suite fungi (31 species including members...
The phylogenetic depth at which arbuscular mycorrhizal (AM) fungi harbor a coherent ecological niche is unknown, has consequences for operational taxonomic unit (OTU) delineation from sequence data and the study of their biogeography. We tested how changes in AM community composition across habitats (beta diversity) vary with OTU resolution. inferred exact variants (ESVs) to resolve phylotypes resolutions finer than provided by traditional clustering analyzed beta diversity profiles up...
Summary A recent study by Sugiura and coworkers reported the non‐symbiotic growth spore production of an arbuscular mycorrhizal (AM) fungus, Rhizophagus irregularis , when fungus received external supply certain fatty acids, myristates (C:14). This discovery follows insight that AM fungi receive acids from their hosts in symbiosis. If this result holds up can be repeated under nonsterile conditions with a broader range fungi, it has numerous consequences for our understanding fungal ecology,...
The microbial communities inhabiting urban soils determine the functioning of these soils, in regards to their ability cycle nutrients and support plant communities. In an increasingly urbanized world properties are utmost importance, responsible worthy exploration. We used 53 grassland sites spread across Berlin describe explain impacts urbanity other environmental parameters upon diversity community composition four groups. These groups were (i) Fungi, with a separate dataset for (ii)...
Abstract Foundation plants shape the composition of local biotic communities and abiotic environments, but impact a plant's intraspecific variations on these processes is poorly understood. We examined links in alpine cushion moss campion ( Silene acaulis ) two neighboring mountain ranges French Alps. Genotyping revealed genetic clusters matching known subspecies. The exscapa subspecies was found both limestone granite, while longiscapa one only limestone. Even similar bedrock, soils from S....
Abstract Aim Deterministic and neutral processes shape the biogeography of fungi. Arbuscular mycorrhizal fungi (AMF), an important group plant root symbionts, remains poorly studied in Neotropics. Here, we provided first molecular survey AMF diversity tested whether environment or space shapes along a 12° latitudinal transect Brazilian Caatinga, unique tropical dry forest ecoregion. Location Brazil. Taxon (Glomeromycotina). Methods Soil samples were collected across 1500 km within Caatinga....
Abstract Open-cast mining leads to the loss of naturally developed soils and their ecosystem functions services. Soil restoration after aims restore agricultural productivity in which fungal community play a crucial role. Whether fungi reach comparable functional state as soil before within half century recultivation is still unanswered. Here, we characterised using ITS amplicon Illumina sequencing across 52-year chronosequence open-cast northern Europe. Both taxonomic composition showed...
