Vulnerability of mineral-associated soil organic carbon to climate across globa...
Díaz-Martínez, Paloma; Maestre, Fernando T.; Moreno-Jiménez, Eduardo; Delgado-Baquerizo, Manuel; Eldridge, David J.; Saiz, Hugo; Gross, NicolasMineral-associated organic carbon (MAOC) constitutes a major fraction of global soil carbon and is assumed less sensitive to climate than particulate organic carbon (POC) due to protection by minerals. Despite its importance for long-term carbon storage, the response of MAOC to changing climates in drylands, which cover more than 40% of the global land area, remains unexplored. Here we assess topsoil organic ca...
Unforeseen plant phenotypic diversity in a dry and grazed world
Gross, Nicolas; Maestre, Fernando T.; Liancourt, Pierre; Berdugo, Miguel; Martin, Raphaël; Gozalo, Beatriz; Ochoa, Victoria; Delgado-Baquerizo, ManuelEarth harbours an extraordinary plant phenotypic diversity1 that is at risk from ongoing global changes2,3. However, it remains unknown how increasing aridity and livestock grazing pressure—two major drivers of global change4,5,6—shape the trait covariation that underlies plant phenotypic diversity1,7. Here we assessed how covariation among 20 chemical and morphological traits responds to aridity and grazing pr...
Hotspots of biogeochemical activity linked to aridity and plant traits across g...
Eldridge, David J.; Ding, Jingyi; Dorrough, Josh; Delgado-Baquerizo, Manuel; Sala, Osvaldo; Gross, Nicolas; Le Bagousse-Pinguet, YoannPerennial plants create productive and biodiverse hotspots, known as fertile islands, beneath their canopies. These hotspots largely determine the structure and functioning of drylands worldwide. Despite their ubiquity, the factors controlling fertile islands under conditions of contrasting grazing by livestock, the most prevalent land use in drylands, remain virtually unknown. Here we evaluated the relative im...
Drivers of woody dominance across global drylands
Biancari, Lucio; Aguiar, Martín R.; Eldridge, David J.; Oñatibia, Gastón R.; Le Bagousse-Pinguet, Yoann; Saiz, Hugo; Gross, Nicolas; Austin, Amy T.Increases in the abundance of woody species have been reported to affect the provisioning of ecosystem services in drylands worldwide. However, it is virtually unknown how multiple biotic and abiotic drivers, such as climate, grazing, and fire, interact to determine woody dominance across global drylands. We conducted a standardized field survey in 304 plots across 25 countries to assess how climatic features, ...
Grazing and ecosystem service delivery in global drylands
Maestre, Fernando T.; Le Bagousse-Pinguet, Yoann; Delgado-Baquerizo, Manuel; Eldridge, David J.; Saiz, Hugo; Berdugo, Miguel; Gozalo, BeatrizGrazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may occur but have never been addressed simultaneously. Using a standardized survey at 98 sites across six continents, we show that interactions between grazing pressure, climate, soil, and biodiver...
