Article Synopsis
  • The study examines the relationship between mycorrhizal types, specifically arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) plants, and their differences in drought tolerance.
  • A global dataset of 1457 woody species was analyzed, revealing that evolutionary history and biogeography affect hydraulic traits in these plants.
  • Findings indicate that AM angiosperms are less drought-tolerant than EcM angiosperms in wetter areas, while AM gymnosperms outperform EcM gymnosperms in dry conditions; overall, AM species show greater variation in hydraulic traits compared to EcM species.

Global soil nitrogen (N) cycling remains poorly understood due to its complex driving mechanisms. Here, we present a comprehensive analysis of global soil δN, a stable isotopic signature indicative of the N input-output balance, using a machine-learning approach on 10,676 observations from 2670 sites. Our findings reveal prevalent joint effects of climatic conditions, plant N-use strategies, soil properties, and other natural and anthropogenic forcings on global soil δN.

Urban greenspaces continue to grow with global urbanization. The global distribution and stock of soil organic carbon (SOC) in urban greenspaces remain largely undescribed and missing in global carbon (C) budgets. Here, we synthesize data of 420 observations from 257 cities in 52 countries to evaluate the global pattern of surface SOC density (0-20 cm depth) in urban greenspaces.

Article Synopsis
  • Crossing certain aridity thresholds in drylands can lead to significant declines in plant productivity and can contribute to land degradation and desertification.
  • Our research found that adding nitrogen (N) to these ecosystems can boost plant biomass and shift the aridity threshold higher, potentially reducing the negative impacts of increased dryness.
  • We predict that under high-emission scenarios, the impact of nitrogen could help mitigate the adverse effects of climate change on vegetation in drylands compared to scenarios without considering nitrogen.

Anthropogenic nitrogen (N) loading alters soil ammonia-oxidizing archaea (AOA) and bacteria (AOB) abundances, likely leading to substantial changes in soil nitrification. However, the factors and mechanisms determining the responses of soil AOA:AOB and nitrification to N loading are still unclear, making it difficult to predict future changes in soil nitrification. Herein, we synthesize 68 field studies around the world to evaluate the impacts of N loading on soil ammonia oxidizers and nitrification.
