Forb species benefit more than grasses from a diverse arbuscular mycorrhizal fungal community in semi-arid grasslands

Yelyzaveta Shpilkina, Martti Vasar, Sergio Asensio, Victoria Ochoa et autres

In exchange for the carbon assimilated by plants, mycorrhizal fungi increase plant nutrient supply, protect them against pathogens and drought, and influence soil formation and aggregation, among other benefits. These processes, in turn, affect the diversity of vegetation and various ecosystem functions, …

Functional restructuring of the global soil microbiome under multiple stressors

Ruirui Chen, Shuhong Luo, Youzhi Feng, Fernando T. Maestre et autres

Microbes, as the planet’s most abundant and diverse organisms, drive soil functions globally and are vulnerable to environmental stressors triggered by global change. Yet, knowledge regarding the impacts of multiple environmental stressors on their functional profiles as well as the consequences for …

Persistence and turnover of soil organic carbon in global drylands

Hui Wang, Fernando T. Maestre, Nan Lü, Guang Zhao et autres

Abstract Reliable predictions of dryland carbon fluxes require understanding the persistence and turnover of soil organic carbon (SOC). We measure radiocarbon to quantify the age of SOC and CO 2 released from soil respiration at 97 dryland sites across six continents. Here …

Limited imprint of modern C sources on soil inorganic C

Hui Wang, Jianbei Huang, Fernando T. Maestre, Nan Lu et autres

Drylands contain most of the global soil inorganic carbon (SIC), yet its sources and vulnerability are poorly constrained. We measured SIC content and its radiocarbon (14C) at 55 dryland sites across Asia and Europe to investigate the origins of SIC and its …

What shapes nitrifiers in drylands? Global drivers of AOA and AOB abundance across microsites

Norah Alghamdi, Mario Corrochano‐Monsalve, Fernando T. Maestre

Nitrifying microbes play a central role in soil N cycling by controlling N transformations and the potential for N losses (including the greenhouse gas N2O). Yet, the drivers of nitrifier communities remain poorly resolved across global drylands, which cover more than 40% …

Climate Shapes the Ratio Between Aboveground Plant Biovolume and Topsoil Macronutrients Worldwide

Tadeo Sáez-Sandino, Emilio Guirado, Fernando T. Maestre, César Terrer et autres

ABSTRACT Soil nutrients are a major limiting factor for plant biomass, yet paradoxically, some of the most productive ecosystems thrive in nutrient‐poor soils. Here, we conducted a global field survey in 421 sites across all major biomes to investigate the environmental factors …

Reviving the desert: Pastoral transitions and rangeland management in the Arabian Peninsula

David John Eldridge, J. Clarence Davies, Victor R. Squires, Fernando T. Maestre

Abstract The grazing of livestock on arid and hyper-arid rangelands is the dominant land use across much of the Arabian Peninsula, and is a human activity of large historical, cultural, and economical importance. In this perspective, we outline the historical trajectory of …

Rainfall-induced microbial resuscitation reveals functional decoupling across biocrust succession

Raúl Román, Fernando T. Maestre, Estelle Couradeau

Dryland ecosystems rely on infrequent rainfall pulses to activate soil microbial communities, yet the fraction and identity of microbes resuscitating after hydration remain unclear. We applied bioorthogonal non-canonical amino acid tagging coupled with fluorescence-activated cell sorting (BONCAT-FACS) and 16S rRNA gene sequencing …

Diverse crop rotations offset yield-scaled nitrogen losses via denitrification

Aurélien Saghaï, Monique E. Smith, Giulia Vico, Samiran Banerjee et autres

Denitrification, a major source of gaseous nitrogen emissions from agricultural soils, is influenced by management. Practices promoting belowground diversity are suggested to support sustainable agriculture, but how they modulate nitrogen losses via denitrification remains inconclusive. Here we sampled 106 cereal fields spanning …
