Item Global homogenization of the structure and function in the soil microbiome of urban greenspaces(Science Advances, 2021) Delgado-Baquerizo, Manuel; Eldridge, David J.; Liu, Yu-Rong; Sokoya, Blessing; Wang, Jun-Tao; Hu, Hang-Wei; He, Ji-Zheng; Bastida, Felipe; Moreno, José L.; Bamigboye, Adebola R.; Blanco-Pastor, José L.; Cano-Díaz, Concha; Illán, Javier G.; Makhalanyane, Thulani P.; Siebe, Christina; Trivedi, Pankaj; Zaady, Eli; Verma, Jay Prakash; Wang, Ling; Wang, Jianyong; Grebenc, Tine; Peñaloza-Bojacá, Gabriel F.; Nahberger, Tina U.; López Teixido, Alberto; Zhou, Xin-Quan; Berdugo, Miguel; Duran, Jorge; Rodríguez, Alexandra; Zhou, Xiaobing; Alfaro, Fernando; Abades, Sebastian; Plaza, César; Rey Muñoz, Ana Isabel; Singh, Brajesh K.; Tedersoo, Leho; Fierer, NoahThe structure and function of the soil microbiome of urban greenspaces remain largely undetermined. We conducted a global field survey in urban greenspaces and neighboring natural ecosystems across 56 cities from six continents, and found that urban soils are important hotspots for soil bacterial, protist and functional gene diversity, but support highly homogenized microbial communities worldwide. Urban greenspaces had a greater proportion of fast-growing bacteria, algae, amoebae, and fungal pathogens, but a lower proportion of ectomycorrhizal fungi than natural ecosystems. These urban ecosystems also showed higher proportions of genes associated with human pathogens, greenhouse gas emissions, faster nutrient cycling, and more intense abiotic stress than natural environments. City affluence, management practices, and climate were fundamental drivers of urban soil communities. Our work paves the way toward a more comprehensive global-scale perspective on urban greenspaces, which is integral to managing the health of these ecosystems and the well-being of human populations.Item Environmental filtering controls soil biodiversity in wet tropical ecosystems(Soil Biology and Biochemistry, 2022) Haiying Cui; Peter M. Vitousek; Sasha C. Reed; Wei Sun; Blessing Sokoya; Bamigboye, Adebola R.; Verma, Jay Prakash; Mukherjee, Arpan; Peñaloza-Bojacá, Gabriel F.; López Teixido, Alberto; Trivedi, Pankaj; He, Ji-Zheng; Hu, Hang-Wei; Png, Kenny; Delgado-Baquerizo, ManuelThe environmental factors controlling soil biodiversity along resource gradients remain poorly understood in wet tropical ecosystems. Aboveground biodiversity is expected to be driven by changes in nutrient availability in these ecosystems, however, much less is known about the importance of nutrient availability in driving soil biodiversity. Here, we combined a cross-continental soil survey across tropical regions with a three decades' field experiment adding nitrogen (N) and phosphorus (P) (100 kg N ha−1y−1 and 100 kg P ha−1y−1) to Hawai'ian tropical forests with contrasting substrate ages (300 and 4,100,000 years) to investigate the influence of nutrient availability to explain the biodiversity of soil bacteria, fungi, protists, invertebrates and key functional genes. We found that soil biodiversity was driven by soil acidification during long-term pedogenesis and across environmental gradients, rather than by nutrient limitations. In fact, our results showed that experimental N additions caused substantial acidification in soils from Hawai'i. These declines in pH were related to large decreases in soil biodiversity from tropical ecosystems in four continents. Moreover, the microbial activity did not change in response to long-term N and P additions. We concluded that environmental filtering drives the biodiversity of multiple soil organisms, and that the acidification effects associated with N additions can further create substantial undesired net negative effects on overall soil biodiversity in naturally tropical acid soils. This knowledge is integral for the understanding and management of soil biodiversity in tropical ecosystems globally.Item The global distribution and environmental drivers of the soil antibiotic resistome(Microbiome, 2022) Delgado-Baquerizo, Manuel; Hu, Hang-Wei; Maestre, Fernando T.; Guerra, Carlos A.; Eisenhauer, Nico; Eldridge, David J.; Zhu, Yong-Guan; Chen, Qing-Lin; Trivedi, Pankaj; Du, Shuai; Makhalanyane, Thulani P.; Verma, Jay Prakash; Gozalo, Beatriz; Ochoa, Victoria; Asensio, Sergio; Wang, Ling; Zaady, Eli; Illán, Javier G.; Siebe, Christina; Grebenc, Tine; Zhou, Xiaobing; Liu, Yu-Rong; Bamigboye, Adebola R.; Blanco-Pastor, José L.; Duran, Jorge; Rodríguez, Alexandra; Mamet, Steven; Alfaro, Fernando; Abades, Sebastian; López Teixido, Alberto; Peñaloza-Bojacá, Gabriel F.; Molina-Montenegro, Marco A.; Torres-Díaz, Cristian; Pérez, Cecilia; Gallardo, Antonio; García-Velázquez, Laura; Hayes, Patrick E.; Neuhauser, Sigrid; He, Ji-ZhengBackground Little is known about the global distribution and environmental drivers of key microbial functional traits such as antibiotic resistance genes (ARGs). Soils are one of Earth’s largest reservoirs of ARGs, which are integral for soil microbial competition, and have potential implications for plant and human health. Yet, their diversity and global patterns remain poorly described. Here, we analyzed 285 ARGs in soils from 1012 sites across all continents and created the first global atlas with the distributions of topsoil ARGs. Results We show that ARGs peaked in high latitude cold and boreal forests. Climatic seasonality and mobile genetic elements, associated with the transmission of antibiotic resistance, were also key drivers of their global distribution. Dominant ARGs were mainly related to multidrug resistance genes and efflux pump machineries. We further pinpointed the global hotspots of the diversity and proportions of soil ARGs. Conclusions Together, our work provides the foundation for a better understanding of the ecology and global distribution of the environmental soil antibiotic resistome.
