Fungi are highly diverse organisms, which provide multiple ecosystem services. However, compared with charismatic animals and plants, the distribution patterns conservation needs of fungi have been little explored. Here, we examined endemicity patterns, global change vulnerability priority areas for functional groups soil based on six surveys using a high-resolution, long-read metabarcoding approach. We found that all most peaks in tropical habitats, including Amazonia, Yucatan, West-Central...
How the multiple facets of soil fungal diversity vary worldwide remains virtually unknown, hindering management this essential species-rich group. By sequencing high-resolution DNA markers in over 4000 topsoil samples from natural and human-altered ecosystems across all continents, we illustrate distributions drivers different levels taxonomic phylogenetic fungi their ecological groups. We show impact precipitation temperature interactions on local species richness (alpha diversity)...
Abstract Lichen symbioses are thought to be stabilized by the transfer of fixed carbon from a photosynthesizing symbiont fungus. In other fungal symbioses, carbohydrate subsidies correlate with reductions in plant cell wall-degrading enzymes, but whether this is true lichen symbionts (LFSs) unknown. Here, we predict genes encoding carbohydrate-active enzymes (CAZymes) and sugar transporters 46 genomes Lecanoromycetes , largest extant clade LFSs. All LFSs possess robust CAZyme arsenal...
Microplastics (MPs) are emerging contaminants in agricultural soil, whereas their effects on the rhizosphere microbial ecosystems and biogeochemical nitrogen cycles during plant growth remain unknown. Here, a 70-day greenhouse experiment was carried out with black fluvo-aquic soil to evaluate influence of polyamide (PA), polyethylene (PE), polyester (PES), polyvinyl chloride (PVC) MPs bacterial communities functions soybean rhizosphere. The PA treatment consistently affected rhizobacterial...
Abstract Natural systems are under increasing pressure by a range of anthropogenic global change factors. Pesticides represent nearly ubiquitously occurring factor and have the potential to affect soil functions. Currently use synthetic pesticides is at an all-time high with over 400 active ingredients being utilized in EU alone, dozens these concurrently soil. However, we presently do not understand impacts interaction multiple when applied simultaneously. Using collected from local...
Forests and woodlands in the West African Guineo-Sudanian transition zone contain many tree species that form symbiotic interactions with ectomycorrhizal (ECM) fungi. These fungi facilitate plant growth by increasing nutrient water uptake include fruiting body-forming fungi, including some edible mushrooms. Despite their importance for ecosystem functioning anthropogenic use, diversity distribution of ECM is severely under-documented Africa. We conducted a broad regional sampling across five...
Summary Fungi play pivotal roles in ecosystem functioning, but little is known about their global patterns of diversity, endemicity, vulnerability to change drivers and conservation priority areas. We applied the high-resolution PacBio sequencing technique identify fungi based on a long DNA marker that revealed high proportion hitherto unknown fungal taxa. used Global Soil Mycobiome consortium dataset test relative performance various depth standardization methods (calculation residuals,...
In this study, we focused on the fact that soil storage conditions in laboratory have never been considered as a key factor potentially leading to high variation when measuring effects of microplastics microbial activity. We stored field-collected soils under four different [room-temperature storage, low-temperature (LS), air drying (AD), and heat drying] prior experiment. Each was treated with tire wear particles (TWPs), activities water aggregate stability were investigated after...
Abstract The impacts of warming on communities and ecosystems are predicted to be significant in mountain because physiological processes, including rates carbon (C) cycling, often more temperature‐sensitive colder environments. Plant biodiversity can also influence C exchange, yet few studies integrate how biotic abiotic factors may directly or interactively impact ecosystem flux. Here, we examine the link between simultaneous changes multiple dimensions plant diversity peak growing season...
Arbuscular mycorrhizal fungi (AMF) form symbioses with many agricultural crops and can improve plant biomass health. The performance of the AM symbiosis is context dependent, for example, usually inoculation AMF Rhizophagus irregularis benefits biomass, but be suppressed by high soil fertility levels. Nevertheless, importance other management practices on AMF, such as fungicides application, poorly understood. Also, pesticide regulations neglect a comprehensive safety testing lawmakers...
Abstract Macaronesia is characterized by a high degree of endemism and represents noteworthy system to study the evolutionary history populations species. Here, we compare population-genetic structure in three lichen-forming fungi, widespread Lobaria pulmonaria two Macaronesian endemics, L. immixta macaronesica, based on microsatellites. We utilize population genetic approaches explore subdivision these taxa Canary Islands, Madeira, Azores, western Iberian Peninsula. A common feature all...
Urbanization is a growing phenomenon affecting soils worldwide. Urban centers have been highlighted as hotspots for global change factors due to heightened anthropogenic activity. However, few studies investigated the multifaceted impacts of (GCFs) acting in concert with urban soils. Thus, objective this study was add GCFs different combinations (0, 1, 2, 5, and 8 simultaneously) three high-urbanity low-urbanity Berlin evaluate their effects on soil parameters functions. We hypothesized four...
