Uncertain role of conservation areas to protect soil biodiversity and functioning
Zeiss, Romy; Delgado-Baquerizo, Manuel; Singavarapu, Bala; Eisenhauer, Nico; Cano-Díaz, Concha; Calderón-Sanou, Irene; Carvalho, Rui P.; Costa, Sofia R.Soil biodiversity and functioning are the foundation of ecosystem sustainability, but we do not know whether current nature conservation areas are efficiently protecting soils. Here, we investigated the contribution of terrestrial nature conservation areas to protect soil biodiversity and functioning across scales. We found no general positive effect on diversity of bacteria, fungi, protists, invertebrates, and...
Forb diversity globally is harmed by nutrient enrichment but can be rescued by ...
Nelson, Rebecca; Sullivan, Lauren; Hersch-Green, Erika; Seabloom, Eric; Borer, Elizabeth; Tognetti, Pedro; Adler, Peter; Biederman, LoriABSTRACT: Forbs (“wildflowers”) are important contributors to grassland biodiversity but are vulnerable to environmental changes. In a factorial experiment at 94 sites on 6 continents, we test the global generality of several broad predictions: (1) Forb cover and richness decline under nutrient enrichment, particularly nitrogen enrichment. (2) Forb cover and richness increase under herbivory by large mammals. (...
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...
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...
The soil microbiome governs the response of microbial respiration to warming ac...
Sáez-Sandino, Tadeo; García-Palacios, Pablo; Maestre, Fernando T.; Plaza, César; Guirado, Emilio; Singh, Brajesh K.; Wang, Juntao; Cano-Díaz, ConchaThe sensitivity of soil microbial respiration to warming (Q10) remains a major source of uncertainty surrounding the projections of soil carbon emissions to the atmosphere as the factors driving Q10 patterns across ecosystems have been assessed in isolation from each other. Here we report the results of a warming experiment using soils from 332 sites across all continents and major biomes to simultaneously eval...
Global hotspots for soil nature conservation
Guerra, Carlos A; Berdugo, Miguel; Eldridge, David J.; Eisenhauer, Nico; Singh, Brajesh K; Cui, Haiying; Abades, Sebastian; Alfaro, Fernando DSoils are the foundation of all terrestrial ecosystems1. However, unlike for plants and animals, a global assessment of hotspots for soil nature conservation is still lacking2. This hampers our ability to establish nature conservation priorities for the multiple dimensions that support the soil system: from soil biodiversity to ecosystem services. Here, to identify global hotspots for soil nature conservation, ...
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...
Global data on earthworm abundance, biomass, diversity and corresponding enviro...
Phillips, Helen R. P.; Bach, Elizabeth M; Bartz, M. L. C.; Bennett, Joanne M.; Beugnon, Rémy; Briones, Maria J. I.; Brown, George G.; Ferlian, OlgaEarthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site l...
